Micro-Master Touch User Guide

1 Introduction

The Micro-Master Touch Irrigation Controller is the latest in a long line of reliable Australian designed and built controllers brought to you by Toro. It uses the latest in microprocessor technology, including a full colour, touch screen LCD display. Each controller consists of a Master Unit, and up to 4 Remote Units.

The Master Unit is supplied with one 8 Station Module, and can be expanded with 8 Station Modules up to a total of 32 Stations.

Remote Units are supplied with one 8 Station Module, and can be expanded with 8 Station Modules up to a total of 32 Stations.

It is not necessary to expand each unit before another Remote Unit is added to the controller. Since each Remote Unit has it's own power supply and is physically separate from the Master Unit, Remote Units can be placed in different locations to the Master Unit. For example, the Master Unit could be located in the main office, and an Expansion Unit could be located in the pump shed, and used to control the pumps, filters and chemical injection system.

1.1

Controller Capabilites

The Micro-Master Touch controller supports various expansion and communication cards. Expansion Modules include 8 station modules, digital input modules, and analogue input modules. Communication cards include RS232 modules, Analogue/GSM/GPRS Modem interface modules,

RS485 modules, USB modules, and Ethernet interface cards. Each Micro-Master Touch controller can be expanded out to 160 stations using additional Remote

controller units (up to 4 units). Communication between units is achieved by RS485 communication modules or through the addition of the Radio-Master for Touch range of wireless modules.

The Touch Controller supports 32 individual irrigation programs. Each program operates independently and can be in sequential or grouping mode. Irrigation Programs can be independently Enabled, (Rain Switched). There are two levels of globally enabling irrigation programs. A global enable and rain switch stops all idle programs from starting but allows currently active programs to complete. Individual programs can be set to ignore the rain switch control.

Programs have the following capabilities:

· Irrigation Units can be seconds, minutes or volumetric,

· Chemical Injection Units can be set independently of the main program. Each chemical has it's

own units and may be seconds, minutes, or volumetric.

· 14 day daytable. Each day can have different number of cycles, and include or exclude chemical injection,

· Up to 8 start times,

· 4 chemicals per group or station,

· Up to 48 groups with up to 40 Stations per group,

· Water budget percentage, 0 to 250%,

· Individual external inputs for starting, stopping, holding and skipping groups/stations,

· Individual Flow Meters for each program, pump, and chemical,

· Staggered programs, where the completion of one program can start another,

· Filter bank support,

· Pump set support.

The chemical system supports up to eight chemicals. Each chemical has individual prewet/mixing times and can be assigned to any station outputs in the

Micro-Master Touch User Guide

controller. Any four of the eight chemicals can be associated with each program. The Filter Bank system supports up to eight separate banks of filters. Each filter bank may contain up to eight filters, and each filter can be assigned to any station output

in the controller. The Pump Set system supports up to eight separate sets of pumps. Each pump set may contain up to four pumps, and each pump can be assigned to any station output

in the controller. Each pump set supports runtime levelling, priority, and can support a VFD as pump 1.

1.2

Do's & Dont's

The Micro-Master Touch controller will give you many years of faithful service, as do all Micro-Master products, but there are certain requirements that should be observed when using the controller, as with all electrical equipment.

· Don't leave the door open when you have finished with the controller. Water entering into the controller via an open door is not covered by your warranty. A burst pipe in a pump shed, for example, can do a lot of damage.

· Do ensure that all wiring holes in the case are sealed. Ants, mice and slugs can also destroy the unit if they are allowed entry and will not be covered by your warranty.

· Don't use metal objects to select icons on the LCD screen. You can destroy the touch pad. A finger, eraser tipped pencil or wand is all that is needed.

· Don't mount the unit where it is exposed to full sun during the day. Temperatures within the unit may become excessive causing it to fail. Always supply some shade from the elements.

· Do install a backup battery. This will support the unit during any minor power outages.

· Don't use any chemical products to clean the LCD display. A slightly moist clean cloth is all that is

required to lightly wipe away any marks.

· Do use an earthed power source as this will supply greater protection for the unit.

· Don't open up the 240v AC side of the controller. These voltages can be lethal, particularly

if water has entered the case. Always use a licensed support person or return the unit for repair.

· In areas with known voltage fluctuations, or frequent 'brownouts', we recommend that the controller be connected to a UPS and surge protection device.

2 About This Manual

Digital interactive copies of this manual in various formats are available for download from http:// www.tdssoftware.com.au/manuals/

This manual (in digital form) has been designed to be context sensitive, and includes many topic links and image hotspots.

Clicking a button in an image will, where possible, cause a jump to the same screen as if the button were clicked on the physical Touch controller.

Where not possible or appropriate, the hotspot links to a paragraph explaining the purpose of the button.

Where appropriate, examples in this manual have been drawn from a real world example. In this example, a treelot is irrigated using recycled water from a storage tank. There are two zones

in the treelot, allocated to Stations 1 and 2, and a flushing valve (station 4) is connected to both zones to drain solids from the line after irrigation. The treelot irrigation program operates in grouping mode. The storage tank is circulated with a five minute on, five minute off cycle repeating 6 times each shift, running four times every day. Two master valves are connected to the irrigation (station

5) and circulation (station 6) mainlines A pump is connected to station 7, an ozone generator is

connected to station 11, and two filters in a single bank are connected to stations 9 and 10. Chemical injection is performed each treelot irrigation. Three level sensors detect when the tank is empty, almost full, and full. The empty and full sensors control the treelot irrigation, and the almost full sensor stops the ozone generator, and stops the circulation program.

A diagram of the real world example is shown below.

3 Controller Part Numbers

The Micro-Master Touch controller is a modular design. The Master Unit is supplied as a minimum, with one 8 Station Module, and can be expanded with 8

Station Modules up to a total of 32 Stations. Remote Units are supplied as a minimum, with one 8 Station Module, and can be expanded with 8

Station Modules up to a total of 32 Stations. It is not necessary to expand each unit before another Remote Unit is added to the controller. Since

each Remote Unit has it's own power supply and is physically separate from the Master Unit, Remote Units can be placed in different locations to the Master Unit. For example, the Master Unit could be located in the main office with one 8 Station Module, and an Expansion Unit could be located in the pump shed, and used to control the pumps, filters and chemical injection system with multiple 8 Station Modules.

4 Installation Instructions

4.1 Wall Mount Installation

On the back of the controller is a “keyhole” shaped mounting slot as well as 2 mounting holes along the bottom edge. These mounting holes are shown circled red in the next picture. Access to the 2 mounting holes is from the front behind the bottom cover plate.

Figure 4 - Back of Micro-Master Touch Controller

When attaching to wall studs use a No. 10 self tapping screw and leave approx. 6mm of the head exposed to slip into the “keyhole” slot. To secure and stabilise the controller, drive additional screws through the bottom mounting holes.

NOTE: When mounting the controller to a sheet metal wall, it is essential to mount timber mounts to the wall first and then mount the controller to the timber. This prevents high temperatures being conducted to the controller.

4.2

Module Installation

The Touch controller uses various modules installed into "slots" on both the motherboard and processor boards to increase its versatility or capacity.

A wide range of modules are available for both the communication slots on the processor board and expansion slots on the motherboard. Both employ a similar method of mounting and are easy to install or remove.

Micro-Master Touch User Guide

NOTE:

Before any installation or removal of a module occurs,

all power to the unit MUST

be removed

, including the backup battery. Never install or remove a module with power

applied. Damage to the module may occur and this is NOT covered by your warranty.

NOTE:

Two screws are used to provide power and to secure the Expansion Modules.

All

screws must be installed

for the Expansion Module to operate correctly.

The motherboard, which is at the bottom of the case, holds all of the field wiring modules, along with a power supply module and Radio-Master for Touch RMT200 module, if fitted.

The Power module (already fitted) and Expansion Slots number 5, 6 & 7 use screws to hold the module in place and are connected to the controller via 8 pins.

Expansion slots 1 to 4 are for the Station(Valve) relay modules, Analogue Input and Digital Input modules. Each of these modules is connected to the controller by a 20 way edge connector and held in place by 2 screws. The screw connection points supply 24V AC and GND to the modules, for the field wiring. Installing a module in slots 1 to 4 is achieved by inserting the tongue of the expansion module into the edge connector until the 2 screw holes align and then fitting the screws.

The tongue of the module is the slightly smaller end that has stripes down the edge, on both the top and bottom sides.

Expansion modules 5 & 6 are fitted on edge. Ensure that all the gold pins enter the header connector on the module and the screw mount aligns with the bracket, then insert the screw. Typically, this is where the RS485 modules would reside, when other remote units are connected using wire.

Expansion module 7 requires the pins to come through the board into the header and 4 screws to hold the module in place.

Remember, no power should be present when installing or removing modules. You may also find a magnetic screw driver of help when trying to install or remove screws.

The processor (or logic) board is the top board in the controller with the LCD screen attached. This board has 2 slots on the right hand side for various types of communication modules to be installed. These modules are shorter than the motherboard expansion modules and should never be interchanged. The connection of the module is achieved by an edge connector and a single screw to hold the module in place. Once again, slide the tongue of the module into the edge connector until the screw hole aligns and then insert the screw.

When you restart the controller, navigate to the Expansion Module Configuration page and initiate a scan by clicking the scan button.

The controller will perform a scan to determine what modules are fitted to the unit and update its configuration.

An example of a motherboard is shown in Figure 5. This motherboard has been populated with 2 8 Station Relay Modules (MMTOUCH-STN) in Expansion Module numbers 1 and 2, an RS485 Remote Expansion Module (MMTOUCH-485E) in Expansion Module number 6 and a Radio-Master for Touch

Micro-Master Touch User Guide

Radio Expansion Module (RMT200) in Expansion Module number 7.

Figure 5 - Touch Motherboard with 2 MMTOUCH-STN,

RMT200 and MMTOUCH-485E modules

4.3

Master/Remote selection

The Micro-Master Touch controller can support up to a total of 160 station outputs. This is dependant on the number of remote units connected and the expansion modules fitted. One Micro-Master Touch Master Unit can support up to four Touch Remote Units, each fitted with a variety of expansion modules.

Configuration of a Touch Unit as either a Master Unit or Remote Unit is performed via a four switch block, numbered 1 to 4, on the motherboard, next to the ribbon cable connector and above Expansion Module number 1.

When configuring units, all power to the unit MUST be removed, including the backup

battery.

To designate a unit as the Master, all switches on the block should be in the OFF position. For Remote Unit number 1, the number 1 switch should be ON, all others OFF. For Remote Unit number 2, the number 2 switch should be ON, all others OFF. For Remote Unit number 3, the number 3 switch should be ON, all others OFF.

Micro-Master Touch User Guide

For Remote Unit number 4, the number 4 switch should be ON, all others OFF. There can only be one Master controller and one of each of the remotes connected as a group. In the example below, a unit has been configured as Remote Unit number 1.

Figure 6 - Master / Remote Selection Switch

4.4

Connecting Valve Wire

1. Remove bottom cover.

2. Route 1 wire from each valve though one of the three holes in the bottom of the controller case. Insert each lead into the appropriate terminal on the connector.

For ease of wiring the connector heads can be removed if required.

3. The common wire for each valve should be attached to a single “Common” wire. Connect this Common wire to one of the terminals labeled COMMON.

4. When all valve wires have been connected, ensure that all holes and spaces between valve wires are sealed with a silicone sealant or similar. This ensures that insects, ants and vermin cannot enter the controller.

Micro-Master Touch User Guide

An example of correctly terminated valve wiring is shown below.

Figure 7 - Wiring Terminal Blocks

4.5

Earth Stake

The Micro-Master Touch controllers have a high level of field surge protection (4500 amp 20usec). For this to work effectively, a good low resistance earth path must be provided to shunt the surges. A resistance value <10 ohms is acceptable. A resistance value between 10-30 ohms is marginal. A resistancevalue higher than 30 ohms is not acceptable. In severe lightning areas a 2 metre earth stake connected to one of the GND terminals can be used ( Use multi-strand 4-6mm wire ).

Ensure soil around the earth stake is kept moist to create a good earth.

4.6

Standby Battery

The Standby Battery is a 9V alkaline MN1604 miniature Battery. This will give several hours of standby time. The alkaline battery is essential in high temperature conditions as they have a shelf life of approximately 5 years at 40 degrees Celsius. In the long term, an alkaline battery will be more reliable and cheaper than an equivalent NiCad battery. They are replaced every 1 to 2 years depending on the number of power failures in the area.

Note: For extreme conditions with many power failures, a battery holder with (6 AA alkaline cells) will give an increased Standby time.

NI-Cad (Nickel Cadmium ) batteries should not be used for 2 reasons.

1. For a Ni-cad to be efficient, the operating cycle should be fully charged, then fully discharged. This is not the case for a Standby battery in an irrigation controller.

2. Poor operation in a high temperature environment. The capacity is only 20% of an alkaline cell and this is further reduced in high temperature environment.

The 216 standard carbon zinc battery should not be used because of very poor high temperature performance and low capacity.

4.7

12 Volt DC Operation

The Touch Series controllers can be easily changed to operate on 12VDC. It should only be used with caution as valves must be fitted locally as wires carrying DC current should not be installed under ground because of electrolysis. Ideal installation when hydraulic valves are used.

Micro-Master Touch User Guide

1. Remove the 4 way connector from the motherboard.

2. Plug in the 12VDC adaptor plug supplied with the controller.

3. Connect the RED lead to +12VDC.

4. Connect the BLACK lead 0VDC.

5. Connect Earth stake as described in the Earth Stake installation instructions.

The Micro-Master Touch contains a large number of setup and configuration options. The various options are described below.

System Setup

The controller setup supports multiple controller ID's within the one installation. To prevent confusion each controller must be assigned a unique controller identification number. Numbers do not need to be sequential.

A system wide date/time subsystem keeps track of day and time. The day and time is used to tag events within the controller.

The controller serial number is a unique factory assigned number. The controller version displays the current revision of the firmware. The firmware number is in the

form xx,yy,zz. Major revisions ( denoted by xx ) may not be compatible with earlier versions of the software or hardware. Minor revision numbers ( denoted by yy ) and indicate updated or added functionality in the firmware. All minor revisions are compatible within a major revision. For example, minor revision 1.4.z is compatible with revisions 1.0.z through 1.3.z. Minor changes to controller firmware are denoted by zz.

Changing the firmware is possible by loading a compatible firmware on to a USB flash storage device and installing the USB device in the front panel USB connector. Selecting the revision in the System Setup window and clicking the Edit icon will request confirmation. If approved, the controller will reboot and attempt to update the firmware from the file on the USB device. If a compatible file is not found, the controller will abort the firmware upgrade and restart.

Global Setup

The controller supports several functions for upgrading, or controller maintenance. The Global Setup screen supports backup of all controller configuration and totals to a connected USB storage device. This file can be used to restore the controller to a known state in the event that the front panel needs to be replaced, or the controller is inadvertently reset.

Options exist to clear the controller totals and logs only, or clear the entire controller configuration to the factory defaults.

For maintenance purposes the controller has two levels of program control. A Global Enable prevents all programs from starting. A rain switch enable prevents programs from starting, unless the program has the Ignore Rain Switch option ticked. By default, all programs obey the rain switch.

It is recommended that after the controller has been installed and configured, a backup of the controller be performed and the USB backup file stored in a safe location.

Unit Configuration

Each Unit can be assigned a name and individually be enabled or disabled. Each Remote Unit can be accessed using RS485 or RMT200 expansion modules. Selecting the Comms item and selecting edit will display a list of available Radio-Master for Touch radio addresses or RS485 addresses. Selecting the scan option on the radio address screen will search the controller network for all Radio-Master for Touch or RS485 based modules.

Micro-Master Touch User Guide

Expansion Module Configuration

Each expansion module in the Master Unit (except expansion module 1) or a Remote Unit can be replaced in the field by a Radio-Master for Touch Field Module. The Expansion Module configuration screen allows selection of the expansion module. Selecting edit will display a list of available Radio-Master for Touch addresses. Selecting the scan option on the address screen will search the controller network for all Radio-Master for Touch Field Modules.

Selecting a radio designates the selected field module as a replacement for the expansion module. If an expansion module has been replaced by a field module, the expansion module in the master or remote unit becomes inoperable. If an Expansion Module in position 1 is replaced by a field module, no communication with a Remote Unit will be possible. Hence it is possible to have up to four radio expansion modules forming a virtual remote unit, without the need for a physical Remote Unit. When Radio-Master for Touch Field Modules are added to a controller, it is recommended that field modules remain separate from Remote Units. For example, if an installation has a Master Unit and 1 Remote Unit (Unit 1), then Field Modules should be added as Unit 2/Module 1 etc.

Access PIN Numbers

The controller supports two options for restricting access to levels of functionality in the controller. Once entered, a valid PIN is active for a user configurable time period. The default time period is 60

minutes. If a PIN is required, the user is directed to the PIN Entry screen. Limited access allows users to view the status of the various subsystems in the controller, and to

control single station and programs. Full access allows users access to all areas of the controller. Only users with full access can change

the PIN numbers. If a PIN number is forgotten, please contact Toro Technical Services for assistance.

Communication Options

The controller supports a number of communication options for connection to outside computing resources. These options are USB, RS232, RS485, Ethernet, WiFi, and GPRS/GSM/Analogue Modems.

Depending on the communication module option installed will determine the parameters available for configuration.

The Ethernet and WiFi communication modules support DHCP address resolution. The WiFi module supports WPA, WEP, and WPA2 encryption.

Diagnostics

The Micro-Master Touch controller contains a variety of diagnostic tools, for isolating faults in the front panel. The ability to produce a log file on an attached USB flash storage device can provide important information regarding the current operation of the controller.

RMT Field Module Installation

Figure 12 - RMT800 Panel with connector positions

Aerial Installation

Figure 13 - Aerial mounted on Solar Panel

Note: Depending on the particular installation environment it may be easier to install the antenna prior to mounting the Solar Panel assembly onto the mast. Remember, the higher the antenna, the better the coverage.

Loosen the nut on the base of the antenna and slide the antenna into the slot located on the top edge of the Solar Panel Mounting Plate.

Retighten the nut on the base of the antenna.

Solar Panel Mounting Bracket Installation

The Solar Panel Mounting Plate has been designed to maximise the average available solar power whilst reducing wind resistance and providing ease of assembly. The angle of the Solar Panel has

Micro-Master Touch User Guide

been optimised for locations near the latitude of Sydney, Adelaide, and Perth, but will provide good operation over most of Australia.

The Solar Panel Mounting Plate kit is supplied with 4 saddle clamps. Both 2” (50mm) and 1” (25mm) water pipe saddle clamps are supplied to allow several mounting options. Only two saddle clamps are required to mount the Solar Panel Mounting Plate.

Attach the Solar Panel Mounting plate to the mast using two saddle clamps and 3/16” bolts and nuts. Orientate the Solar Panel Mounting Plate so that the dark face of the Solar Panel is facing the

direction of the midday sun. This is approximately North and maximises the Solar Panel output. Tighten the 3/16” nuts. Route the Solar Panel power cable and antenna cable to the RMT Field Module. Secure the cables

using cable ties or other appropriate means.

RMT Field Module Installation

NOTE: It is important for the correct and continued reliable operation of the RMT Field Modules that cables and wires are not subjected to deformation or damage during installation or normal use. During installation, ensure that cables and wires are not positioned or routed such that deformation of cables or wires could occur. Routing of the antenna cable should not result in a bend radius of less than 75mm.

Using appropriate fasteners, attach the RM106 Module Mounting Plate in the desired position using the two ¼” holes located at the top and bottom of the Module Mounting Plate. Using the 3/16” bolts and nuts attach the RMT Field Module to the Module Mounting Plate and tighten.

Remove the front cover of the Radio-Master for Touch Field Module. Connect the antenna cable by passing the gold coloured cable connector through the left hand cable

gland on the bottom of the RMT Field Module. Route the antenna cable such that a Rain drip loop is formed. The apex of the loop should hang below the bottom edge of the RMT Field Module case. Take the antenna cable connector and gently screw it onto the gold antenna connection protruding from under the keyboard panel. Ensuring that the cable is not under stress tighten the gland to exclude water and pests. Damage caused by water and pests (ants, slugs, mice, etc.) is not covered under your warranty.

Connecting the Solar Panel Cable

Loosen the right hand cable gland nut and insert the Solar Panel power wires. Strip 5mm of insulation from the Solar Panel wires. Connect the red Solar Panel wire to the Connector Block Pwr position labelled”+” and connect the

blue or black Solar Panel wire to the Connector Block Pwr position labelled “-“. Tighten the cable gland nut.

Connecting the Battery Cable

The battery connector which was unplugged for shipment should now be connected to the Batt position on the right hand side of the RMT Field Module board, next to the Pwr connector. This must be done in order for the unit to function correctly.

Powering the RMT Field Module from a RM101 Plug Pack

Ensure the RM101 Plug Pack is not plugged into the 240V mains wall socket. Remove the connector from the cable by cutting the 2.1mm plug from the RM101 Plug Pack cable.

Micro-Master Touch User Guide

Loosen the right hand cable gland nut and insert the plug pack wires. Separate the plug pack wire into the two conductors and strip 5mm of insulation from each wire. Connect the wire with the white stripe to the Connector Block Pwr position labelled ”+” and connect

the other wire to the Connector Block Pwr position labelled “-“. Plug the RM01 Plug Pack into a 240V mains wall socket and switch on. Using a voltmeter on at least

a 20V DC range, confirm that a nominal 12Vdc is present across the Connector Block Pwr position. Tighten the cable gland nut.

Connecting Valve Wire, All Radio-Master for Touch Modules

The RMT Field Module is designed for 2 wire solenoid operation; 12V is momentarily applied across the connector block positions labelled “L” and “U” for each valve when commanded on or off by a Micro-Master Touch controller.

Loosen an appropriate cable gland nut and insert the solenoid wires. Strip 5mm of insulation from the solenoid wires. Connect the solenoid latch wire to the Connector Block positions marked “L” for the appropriate valve

number. For a Bermad S985 solenoid the Latch Wire is White. For a Baccara 2 wire latching solenoid the Latch wire is Green.

Connect the solenoid unlatch wire to the Connector Block positions marked “U” for the appropriate valve number as shown in the previous picture. For a Bermad S985 solenoid the Unlatch Wire is Red. The Black wire is unused. For a Baccara 2 wire latching solenoid the Unlatch wire is Black.

Tighten the cable gland nut. To prevent insect infestation, any gaps should be eliminated, by tightening the cable glands securely,

or filling the gaps with a suitable all weather sealant.

Connecting Digital Sensors, RMT440D Field Modules

The RMT440D is designed to accept four digital pulse sensors. The RMT440D inputs accept voltage free contact closures. The sensor wiring positions are on the left hand side connectors and marked 1 to 4 with + and – positions. The – position goes to ground, and the + position to the sensor output as shown in Figure 14.

Interfacing the RMT Field Module module with a Micro-Master Touch Master

The Valve outputs of each RMT Field Module are numbered 1 to 8. Each RMT Field Module module will replace 1 Expansion Module from slot 2 to 4 in the Master unit, or, any or all Expansion Modules in a Remote Unit. This means that you can have a mix of a Master, Remotes and RMT Field Module’ s, or a Master and all RMT Field Module’s. This allows maximum flexibility when designing and using the system. The only condition is that slot 1 in the Master must always be a Station Module.

The radio system in the Touch controllers allows use on up to 8 separate channels. By default, the radio channel is set to channel 1. If multiple Touch systems have been installed in the surrounding area it may be necessary to select another channel. The channel of the Master Unit dictates the channel to be used in the RMT Field Modules. If the channel is set to 2 in the Master, then the channel must be set to 2 in all Remote Units and RMT Field Modules that you wish to use with that Master Unit. This only needs to be done if you are not going to use the default settings.

Once setup and turned on, the RMT Field Module will automatically announce and configure itself in to the Touch Master Unit.

Resetting the Module back to Factory settings

Resetting the module back to the factory settings can be achieved easily. Ensure that the unit is turned off. Press and hold the SET key then turn the unit on. This will reset the module to Channel = 1, PosiSense = off, Unit = 0, Module = 0. All LEDs will flash 3 times.

Setting the Channel Number

By default, the channel number is set to 1. Figure 12 shows the front panel of the RMT Field Module. It can be seen that many of the keys have multiple functions.

To set a new channel number, ensure that the unit is turned on, then, in order, one button at a time, press SET, CHANNEL and the number of the new channel to use (1 to 8). You will have 5 seconds

Micro-Master Touch User Guide

between each key press. If you take longer than 5 seconds between each key the command sequence will abort and no change will be effected. Once entered correctly the module will flash the ON LED 3 times.

Setting the Unit Number and Expansion Module Slot Number

The RMT Field Module is capable of being a member of the Master Unit (Expansion Modules 2-4) or any Remote Unit ( Expansion Modules 1 to 4). Use the guide below to set the relevant unit and module ID.

To join the Master Unit press, SET, UNIT, SET. ie. press SET followed by UNIT(1) followed by SET. The ON LED will flash 3 times.

To be part of Remote Unit 1 press, SET, UNIT, 1. To be part of Remote Unit 2 press, SET, UNIT, 2. To be part of Remote Unit 3 press, SET, UNIT, 3. To be part of Remote Unit 4 press, SET, UNIT, 4. Then select the Expansion Module position this module is to occupy by pressing, SET, MODULE,

followed by 1, 2, 3, or 4. The ON LED will flash 3 times. Remember only 2 to 4 is valid for the Master Unit and ensure the module position is vacant, as a

RMT Field Module will take priority over an installed expansion module.

Setting PosiSense

The RMT Field Module is capable of supporting non-PosiSense and PosiSense solenoids in any mix across the valve positions. Setting PosiSense is achieved in a similar manner as described above. The ON LED will flash 3 times on a successful command.

For example, pressing SET, PosiSense, BERMAD, 2 will set output 2 as a Bermad solenoid. Pressing SET, PosiSense, BACCARA, 7 will set output 7 as a Baccara solenoid. Pressing SET, PosiSense, OFF, 1 will turn off PosiSense on output 1. PosiSense should be turned

off if an RM401 Pump Start Relay is connected to the output. Any option selected without an output number at the end will have the effect of a blanket change on

all outputs. For example, pressing SET, PosiSense, BERMAD (with no number keyed for 5 seconds), will set all

outputs for a Bermad solenoid. Pressing SET, PosiSense, OFF (with no number keyed for 5 seconds) wil turn PosiSense OFF for all

outputs.

LED Indicators

The RMT Field Module has 5 LED lights across the right hand top of the keyboard panel. These are marked as ON, OFF, PWR, RX & TX and behave as follows:

ON – flashes when a valve is turned on by pressing a valve key on the keyboard. It is also used to show the valid entry of a setup command via the keyboard. OFF – flashes when a valve is turned off by pressing a valve key on the keyboard. PWR – Shows power to the module and the state of the radio connection. A solid ON or OFF

indicates a power issue, or a radio issue with the radio being unable to join the radio network. A

Micro-Master Touch User Guide

double flash approximately every 5 seconds indicates a successful network connection. RX – flashes when data is received by the module. TX – flashes when data is transmitted by the module.

Turning Valves On & OFF manually

To turn a valve ON & OFF press the relevant button numbered 1 to 8 on the keyboard. When the key is pressed the ON LED will flash to show the valve is turning on, or, the OFF LED will flash is the valve is being turned off. Repeated pressing of the selected valve will turn the valve on and off.

6 Micro-Master Touch Screen Introduction

Each screen in the Micro-Master Touch controller has been designed to follow a common layout whenever possible. This serves to simplify the familiarity process and greatly ease the operation of the controller.

Generally, from the Home Screen, each major function area shows a list of eight function entries, eg a list of programs, list of pumps etc. If there are more than eight entries in the function area, a row of four navigation buttons along the bottom of the screen allows access to the next list of eight entries. When necessary, the labels of the four buttons changes to allow access to further entries.

The right hand side of the screen contains action buttons. Depending on the function area, these buttons will initiate commands on the selected entry, or allow access to the editing functions for the selected entry.

On the edit screens, buttons in the navigation area allow the user to accept, or cancel any changes to the function parameters, or navigate to the next entry in the function. A home button returns the user directly to the main menu, without saving any changes to the function. A help button shows information relating to the function.

On the right hand of the edit screen, a number of action buttons allow further modification of the functions parameters. As far as possible, these buttons will have similar affects on each screen they are displayed.

For example, consider the Pump Set Edit Screen as shown in Figure 20, where the Action, Navigation, and Function Parameter areas are shown.

Figure 20 - Touch Screen Layout

In the Action Area, icons represent various actions that will be applicable for the currently displayed function. Not all icons will be displayed for all functions.

The advanced parameter edit button will display more advanced parameters, including parameters that are unlikely to change frequently, and status and totaliser data for the function.

The log button displays a graphical log of parameters appropriate to the function. In most cases, this will be a graph of the associated flow meter.

Micro-Master Touch User Guide

The copy button prompts the user for a number using the number edit screen, and if accepted, copies the current function parameters into the new function subsystem. This allows users to copy

complete function setups from one function to another. An example of this includes a number of programs that are identical except for different water budgets or prestart delays.

The delete/erase button erases the selected function parameters to factory defined default values. If this button is clicked when the name parameter is selected, the user is prompted to confirm

the reset of all function parameters to factory defined default values.

The edit button edits the selected function set or parameter depending on the type of page displayed. The screen displayed depends on the type of parameter to be changed.

In the Navigation Area, icons represent actions to move between function sets, or between pages of information for the current function set.

The accept button accepts changes to the function set and returns the screen to the function set list. This button must be pressed to save any changes the function configuration. If the screen

timeout occurs before the accept button is pressed, all current modifications will be lost.

The cancel button cancels all changes, including changes in the advanced edit screens, and returns the screen to the function set list.

The home button cancels any changes to the function set and displays the Home Screen.

The help button shows the help screen, containing appropriate help information for the currently displayed screen.

Clicking a page selection button will display the eight function sets listed under the button. This

type of button is used when lists of function sets are displayed. If there are more than 32 function sets for the function, clicking the first or last page selection button will change the function sets listed under the buttons.

The and buttons are used when editing a function set. Clicking one of the buttons will accept any changes to the function set and displays the previous or next function set. In the

advanced parameters edit screens, clicking these buttons show the previous and next advanced parameters edit screens.

The and buttons displays more information for the current function set. For example, when editing a program, clicking this button will display the previous or next 4 groups. The display

wraps at the start and end of the groups, hence if the first 4 groups are displayed, clicking this button will display the last 4 groups.

9 Multi Station Programs

9.1 Overview and Operation

The Micro-Master Touch controller supports 32 independent multi-station programs. All programs operate independently of each other, hence programs can operate concurrently or overlapped if required. Overlapping programs allows programs to control different areas or to perform different functionality without affecting other programs. For example, one program can be used for irrigation, whilst another program might be controlling security lights.

Irrigation Programs can be set up in two different modes

1. Sequential Irrigation

2. Group Irrigation.

Program Operation

When the Micro-Master Touch controller is powered on, all enabled programs are in the Idle state. When a program is due to start according to the Day Table and Start Times, or the Start Control Input is closed, the program will decide whether to execute a Prestart Delay or continue to Starting. If a PreStart Delay has been set, the program starts the Pump Set, then counts down the set PreStart Delay. At the conclusion of the delay, the program starts the first group in the program. If an InterStation Delay has been set, the delay is inserted between each station in the group. The program then moves to the Active state.

In the Active state, the program counts down the runtime, while monitoring the Control Sensor Inputs. If a Control Sensor input becomes valid, the appropriate action is executed. When the group runtime expires, the program determines the next valid group and moves to the Change Group state. The program attempts to maintain a consistent number of active stations while changing groups. If there are no delays, stations on the same Expansion Unit are turned on and off at the same time. If there is an InterStation Delay, but no Group Delay, the controller will turn off one station in the current group and turn on one station in the next group, before delaying for the InterStation Delay time. If there is a Group Delay time set, then all of the stations in the current group are turned off (with an InterStation Delay, if set), the program delays for the Group Delay time and the stations in the next group are turned on (with an InterStation Delay if set).

For example. A program has stations 1, 2, 3 in group 1, and stations 3, 4, 5 in group 2, and has an InterStation Delay, and no Group Delay. When group 1 completes, the controller will turn off station 1 and turn on station 4 at the same time. The controller will then delay for the InterStation Delay time. Then the controller will turn off station 2 and turn on station 5 at the same time. Station 3 continues to operate through the group change.

When all programmed groups have run, the program stops the pump set, and filter bank. If a Cycle Delay is set, and more than one cycle is programmed, the program enters the Cycle Delay state. At the expiration of the Cycle Delay, the program will restart the irrigation, using a PreStart Delay if one is set.

After all cycles have completed, the program stops the pump set and filter bank, starts the next program is one has been set, and enters the Idle state, ready to run the process again when required.

The Irrigation Program operation is shown in Figure 23.

Sequential Programs

Sequential Programs have a runtime allocated to each individual station output. Irrigation will begin at station 1 and end at the last station programmed. This is a simple way of programming if only one station at a time is being irrigated. Stations with a runtime of zero are skipped.

Grouping Programs

A Grouping Program can have up to 48 groups of up to 40 stations. Due to electrical limitations only eight valves per master/remote unit are allowed. Each group has an individual group runtime. Each group can have up to four chemicals assigned. The same four chemicals are used in all groups of a program, however the runtime for each chemical in each group can be different.

Any station can be in one or any number of groups. A group may contain no stations. i.e. As a program delay.

If several pumps are used during a program, the pumps can simply be loaded into the groups with the stations. When the group of stations is switched on, the pump will be switched on at the same time.

Use Program 1 Config

Each program, by default, shares some configuration parameters with Program 1. These parameters include modes and units, delays, control sensors, pump sets, filter banks and flow meters. These parameters are shown with a '*' next to the name on the display during edit functions. Changing a shared parameter will change the parameter for all programs that have 'Use Program 1 Config' enabled. When 'Use Program 1 Config' is disabled for a particular program, the shared parameters are copied from Program 1 to the particular program and then are specific to that program.

In this way the majority of situations will only have to set basic irrigation parameters once. Complicated and specialised programs can then be individually programmed.

Water Budget

Each program has a water budget. Water budgets can be set from 0% to 250% in increments of 1%.

Enabled Programs and Rain Switch

Each program can be enabled or disabled. In conjunction with program enabling, a global rain switch is available. A program must be enabled and the global rain switch must be off for the program to run. An option to force the program to ignore the global rain switch is available in the Advanced Parameters pages.

Irrigation Units

Group or station runtimes are entered as a number of units. The available units are hours:minutes, minutes:seconds, or volumetric. If the selected Irrigation Unit is volumetric, the units used for irrigation are the same as the units of the allocated flow meter.

For example, if flow meter 1 has been set with units of kilolitres, and program 1 irrigation unit is volumetric and uses flow meter 1, then the values entered for each group of station in program 1 will be kilolitres.

Injection Units

Units for chemical injection can be either hours:minutes, minutes:seconds, or volumetric. If the selected Injection Unit is volumetric, the actual units used are the same as the units for the flow meter allocated to the chemical.

Micro-Master Touch User Guide

Next Program

Each program has an option to start another program when the program completes. This option allows staggered programs without manually adjusting start times when runtimes are modified. An example where this feature could be used is a situation where, in order to prevent nozzle blockage or the formation of algal booms, a cleansing flush of clean water is sent through the lines after dirty or recycled water has been used.

Day Table and Cycles

Each program has its own day table and cycle counts. Irrigation is based around a 14 day cycle. For each day, three options can be selected.

1. No Irrigation

2. Irrigation Only

3. Irrigation with Chemical Injection

For each day, the required number of cycles can be set to between 1 and 99 cycles. Eight starts times are available. If a program is started manually (ie without a start time), the program will use the day table and cycle

counts to determine the required irrigation. If Irrigation Only, or Irrigation with Chemical Injection are selected for the current day, then that mode will be used. If No Irrigation is selected for the current day, the program will run irrigation only. If a number of cycles more than 0 is entered, the program will run the entered number of cycles. If the number of cycles entered is zero, the program will run once.

Program Delays

The Micro-Master Touch controller has 4 different delays.

PreStart Delay

If set, a PreStart Delay begins at the set start time, or when start is pressed, or the Start Sensor input is valid. If allocated, the program's Pump Set is started during the PreStart Delay. A PreStart Delay is designed to allow systems which require pressurisation, or some other delay before the main irrigation starts. An example would be a tank filling phase at the beginning of irrigation.

Station Delay

If set, a Station Delay is inserted between each station in a sequential program. In a grouping program, the station delay is inserted between each station in the group. The Micro-MasterTouch Controller attempts to maintain flow during a group change. If a Station Delay is set, the controller will turn off 1 station from the current group, and turn on 1 station from the next group at the same time. For example, if group 3 contains stations 1, 2, 3, and group 4 contains stations 7, 8, 9 and the station delay is 5 seconds, at the conclusion of the runtime for group 3, the controller will turn off 1, turn on 7, then delay 5 seconds, then turn off 2, turn on 8, delay another 5 seconds, and finally turn off 3, turn on 9.

Group Delay

If a Group Delay is set, a delay is inserted between each group in the program.

Cycle Delay

If a Cycle Delay is set, and the irrigation requires more than 1 cycle, a delay is inserted between the conclusion of the last station group and the commencement of the first station group in the next

Micro-Master Touch User Guide

cycle. If the PreStart Delay is set, the PreSet Delay is executed for each cycle.

Control Inputs

The Micro-Master Touch controller includes a large array of control sensor inputs to control irrigation. The available inputs include switch inputs, analogue 4-20mA sensors, flow meters (analogue, pulse, or aggregate), and rules.

Switch inputs are considered valid when closed. Analogue Sensors are considered valid when the measured value exceeds the set alarm value for

the sensor. Analogue, Pulse, and Aggregate Flow Meters are considered valid when the measured flow exceeds

the set alarm value for the flow meter. Rules are considered valid when all of the input conditions for the rule are met.

Start Sensor

The Start Sensor will start irrigation when valid.

Stop Sensor

The Stop Sensor stops the current irrigation when valid.

Hold Sensor

The Hold Sensor will hold (pause) the current irrigation for the time the hold sensor is valid.

Skip Sensor

If the Skip Sensor becomes valid, the current program will stop the current group or station and progress (skip) to the next group or station. The program will continue to skip while the Skip Sensor is valid. If the number of skips exceeds the Skip Count, the irrigation is stopped.

Pump Set

Each program can have it's own Pump Set. Pumps Sets can be either a Pump Set from the Pump system, a single station program, or an output on the front panel.

Filter Bank

Each program can have it's own Filter Bank.

Flow Meter

Each program can have it's own Flow Meter.

10 Single Station Programs

10.1 Overview and Operation

Each Station in the Micro-Master Touch controller can have it's own independent program. Each Station program can be enabled or disabled. Station programs can be time or volumetric based. Stations can be assigned Pump Sets, Filter Banks, and Control Inputs, and has it's own Day Table. If desired, a Station Program can use the same parameters as Station 1.

Station Operation

When a Station program starts, the assigned pump set is also started. If a PreStart Delay has been set, the Station is not started until the PreStart Delay has expired. When the PreStart Delay completes, the Station is started for the specified runtime. If the irrigation units are volumetric the volume units are the same as the allocated Flow Meter. When active, the Station program can be held by an allocated Hold Input, or held by a keyboard hold. Irrigation will recommence when neither a keyboard, of control input hold is active. When the runtime is complete, and more than 1 repeat cycle has been specified, the Station enters a Cycle Delay. When the Cycle Delay expires, the Station will begin the PreStart Delay (if set), or start the Station. When all repeat cycles have run, the Station stops.

The station operation is shown in Figure 34.

11 Pump Sets

11.1 Overview and Operation

The Micro-Master Touch controller supports up to eight pump sets. Each individual pump set can consist of up to four pumps. Each of the four pumps can allocated to any station output in the controller. Each pump set can be enabled or disabled. Additionally, each of the four pumps can be individually enabled or disabled, have a priority assigned, and a pump capacity. If installed, a pump set can be allocated a flow meter. Each program, or single station program can use one of the pump sets.

Pump Set Operation

When a program or single station program starts, the assigned pump set is also started. If a pump on delay is set, the pumps are delayed by the set time. Depending on the parameters for the pump set, one or more of the pumps will start.

If no flow meter is allocated, all allocated pumps will start at the same time, or with a delay set by the inter pump delay setting.

If a flow meter is allocated, further pumps will be started or stopped as required based on the flow rate from the flow meter.

If the VFD pump setting is ticked, pump 1 will always be the first pump started. If the runtime levelling setting is ticked, the next pump to be started will be pump with the lowest total run time. If the runtime levelling setting is not ticked, the next pump to start is determined by the pump priority. If any pump priorities are the same, the first pump in numerical order is started. The VFD setting has precedence over runtime levelling, which has precedence of the pump priority.

When the flow rate reduces sufficiently, pumps will be turned off in the reverse order in which they were turned on. When a program stops, and a pump off delay is set, the pump set will continue to run for the set time. At the end of the pump off delay, any running pumps are stopped. If an inter pump delay is set, the pumps are turned off using the inter pump delay.

The pump set operation is shown in Figure 42.

Each pump can be connected on any station output in the Touch controller units. Each allocated output can be a station on any Remote Unit, or it can be an output (OUT 1 to OUT 4) on the control panel. Allocated outputs do not have to be on the same Remote Unit or Expansion Module.

Priority

Pump priority can be used to change the running order of each of the pumps.

Capacity

If a Flow Meter is allocated to the pump set the capacity is used to determine which pumps should be started, based on the measured flow.

Pump On Delay

The Pump On Delay can be used to stop pumps starting for a set period of time after a program has started.

Inter Pump Delay

The Inter Pump Delay can be used to ramp up the pump set from idle to full pump operation. For example, where no Flow Meter is allocated, all enabled pumps would normally start together. A delay between pump starts may reduce the electrical power required at pump start, and prevent hydraulic shock to the system water pipes.

Pump Off Delay

The Pump Off Delay can be used to keep pumps running for a set period of time after a program has stopped. For example, this may be required to maintain pressure in the system until all valves have closed.

VFD Pumps

If a VFD pump is utilised, it must be entered as pump 1. If enabled, a VFD pump is always started first.

Runtime Levelling

Runtime Levelling allows multiple pumps to be cycled so that the total run time for each pump can be approximately the same. The pump with the lowest total run time is selected before others. Runtime levelling helps to maintain consistent wear between pumps and can assist in scheduling preventative maintenance for the pump set.

Pump Priority

Pump priority can be used to change the running order of each pump.

Allocated Flow Meter

If required, a pump set can automatically switch on and off pumps according to a measured flow. If no Flow Meter is allocated, all enabled pumps will operate according to the pump set parameters. The allocated Flow Meter can be either a Flow Meter or an Aggregate Flow Meter.

Micro-Master Touch User Guide

Flow Meter Delay

When a pump set is running it will periodically check an allocated Flow Meter. Depending on the hydraulics of the irrigation system and the pump set capabilities a delay may be required to allow the system to stabilise before automatically adjusting the pumps for the measured flow. This delay can be set in this setting.

12 Filter Banks

12.1 Overview and Operation

The Micro-Master Touch supports up to eight independently controlled filter banks. Each filter bank can be used to control back-washing for up to eight separate filters, each with individual runtimes. A filter bank can be activated in response to a pressure differential actuation or a regular time interval.

Each filter within the filter bank can be assigned to any station output located in any Remote Unit, or to any of the four outputs on the front panel.

Each filter bank can be named and can be enabled or disabled for maintenance.

Filter Bank Operation

When a program starts, the allocated filter bank enters an Initial PD Delay. During this delay any changes on the PD Input are ignored. This allows a period of time for the system to stabilise before filter washing may be initiated. Following the Initial PD Delay, the filter bank enters a PD Backup Delay. During this delay, a switch closure on the PD Input will start a filter back-wash cycle. If the PD switch fails, the delay ensures that filter cycle will occur at regular intervals. When a filter cycle is started, the filter bank will cycle through allocated filters, running each filter for the specified time. If an Inter Filter Delay is specified, a delay is inserted between each filter activation. When all allocated filters have been run, a filter cycle delay is started. During this delay, any switch closures on the PD Input are ignored. This delay ensures that filter back-washing does occur continuously in the event a short circuit develops in the PD Input wiring.

The filter bank operation is shown in Figure 48.

Filter Bank Parameters

Chemical Injection Pause

Each filter bank has an option to suspend chemical injection when a filter backwashing cycle is in progress. This can be useful to prevent the emission of chemicals in the filter waste water outlet.

Initial Pressure Differential Delay

Delay before the controller will look at the PD Sensor When an irrigation cycle commences, the Initial PD Delay is an adjustable time period before the

controller looks at the PD switch to see if a filter cycle is requested. This is to allow the system sufficient time to stabilize before a flushing cycle commences, as further initial de-stabilization may result from a premature filter cycle actuation immediately after pump start. The contacts from the PD switch must remain closed for the duration of Delay 1 Time specified in the switch sensor. This is to prevent false filter operation during irrigation when the pressure may vary during station change over.

Filter Cycle Delay

Minimum Time between Filter Flushing Cycles. This is the delay time between filter back-flush cycles. It acts in conjunction with the PD switch and

effectively delays a Pressure Differential induced flushing sequence for a period of time to allow system stabilization after the completion of a back-flush Cycle. A typical minimum delay might be 5 minutes when a PD switch is used.

P.D. Switch Backup Delay

Max. Time between Filter Flushing Cycles. A filter program cycle is started if an unusually long time has elapsed between Pressure Differential

initiated back-flush cycles. Each Filter Bank has a backup timer which will actuate in the event of PD switch failure. If a filter

backwash cycle is required on a regular time interval, then the time between the end of one filter cycle and the start of the next is given by the sum of the Filter Cycle Delay and the PD Switch Backup Delay.

Filter Inter-Station Delay

This is the time delay between a filter station switching off and the next filter station switching on. A time between 0 to 99 seconds may be entered. This allows time for the system to stabilize before back-flushing the next filter.

The interaction between the delays described above is shown in the next diagram.

13 Chemicals

13.1 Overview and Operation

The Micro-Master Touch supports up to eight independent chemicals. Each Chemical can be named and can be enabled or disabled. Each chemical can be assigned to one station output located in any Remote Unit, or to one of the

four outputs on the front panel. Each chemical may have its own flow meter or may use the same flow meter as the irrigation program. Chemicals may have different irrigation units, either hours and minutes, minutes and seconds or volumetric. If volumetric irrigation is selected, a flow meter must be assigned and the units will be the defined by the selected flow meter.

Chemicals may have pre-wet or mixing times, and can be selected to continue mixing during injection. The delay between program start and the commencement of injection is to allow sufficient time for agitation of dissolved chemicals and a degree of soil pre-wetting to aid in the dispersal and penetration of the chemical into the soil. The Pre-wet / Mixing time is always in minutes and seconds.

Chemical Injection Operation

When chemical injection is required by an irrigation program, the chemical injection begins the prewet/mixing time delay. If this delay is zero, chemical injection begins immediately. If a delay is set, and no station output is assigned to the preset/mixing station parameter, the delay time still activates. When the delay times out, the allocated station is activated for the time specified by the irrigation program. When the time completes or irrigation volume is reached, chemical injection is stopped and the chemical returns to idle.

If the irrigation program enters a hold condition during injection, the chemical is also held. If 'mix during injection' is enabled, the mixing station output will remain activated during hold. If the hold condition is activated during the prewet/mixing delay, the mixing station output will remain activated, but the delay will continue until completion, when the chemical will immediately be put on hold.

The chemical injection operation is shown in Figure 54.

14 Control Sensors

14.1 Overview and Operation

The Micro-Master Touch supports a variety of control sensors. These sensors include Rules, Aggregate Flow Meters, Flow Meters, Switch Inputs, Digital Sensors, Analogue Sensors, and Rain Bucket Sensor.

Rules allow a number of sensors to be combined to produce logical outputs to allow sophisticated control scenarios to be implemented.

Aggregate Flow Meters are an arithmetic combination of up to four flow meters. Flow Meters are independent flow meters, which may use one of the Switch Sensors on the main

screen panel, or one of the Digital or Analogue Sensors located in one of the Expansion Module positions.

Switch Sensors are the eight inputs located on the main screen panel. Digital Sensors can be located in one of the Expansion Module positions and can be used as general

purpose inputs for use as a parameter in rules, or as a pulse flow meter. Analogue Sensors can be located in one of the Expansion Module positions and can be used as

general purpose inputs for use as a parameter in rules or as an analogue flow meter.

Control Sensor Operation

Generally, each control sensor has similar action. With slight variations, a control sensor can either be Idle (or Open), Active (or Closed), or Triggered. For example, a switch input and digital input will be either open, or closed. Analogue Sensors, Aggregate Flow Meters and Flow Meters can be Idle (0 flow or value), Active when flow is detected, or triggered when a adjustable trigger point is reached.

Rules use a variety of inputs to produce an output that is either Idle, or Triggered. Inputs to rules can be any other sensor, program, station, or system parameter. When all of the input conditions are met, the rule is triggered. A triggered rule can be used as a control input start, reset, hold, or skip any program or station. Rules can also be used to control various system parameters.

14.3 Rules

14.3.1 Overview and Operation

The Micro-Master Touch supports up to thirty two independently controlled rules. Although each rule is independently controllable, rules can be used as inputs to other rules, allowing a sophisticated nested rule structure.

Each rule can have four inputs. Each input can be sourced from various sources. It could be the active status of a program, station, filter, chemical, or pump. It could be the state of any control sensor in the control sensor system, including the output from another rule. Obviously, care needs to be taken to ensure circular rules do not occur, where a change in state of one rule does not directly change the inputs to the same rule, causing the rule to continuously change the output of itself.

Rule Operation

When a rule is Enabled, the rule checks the condition of it's input control sensors every second. If all of the conditions for the input control sensors are met, the rule is considered to be triggered, or active. When any one of the input control sensor conditions are not met, the rule becomes idle, or untriggered.

The rule operation is shown in Figure 59.

Rule Details

Rule setting follows a simple process. If an IF rule option is left blank it is ignored. The IS option can be True or False. The logic box must

be either

or OR. Mixing of True and False statements is allowed. Once AND or OR is selected

it applies to all statements in the rule. i.e. Condition 1

.........

Then

Do(

Start,Stop Hold,etc

) a

Target(

Program, Station, etc

) is a simple example.

Also remember that a Rule can also be used to trigger another rule. This allows multiple rules to be used to monitor complex requirements.

When creating rules always check if once a rule is in action, that the action will stop at some point in time. If not, create a rule to force a stop when a set limit is reached.

Case 1 example: A dam and tank both have float sensors that close when the dam or tank is empty. Program 1 is a

program that irrigates from the tank. Program 2 runs a transfer program to move water from the dam to the tank. When the tank is empty we want to hold Program 1, while the tank transfer program runs.

Therefore a rule that would encompass this scenario would be, "If Tank IS True (Empty) AND Dam IS False (not Empty), START Program 2 (Tank Transfer)". The Hold Sensor input for Program 1 (Irrigation) can be set to Program 2.

This rule would work in the following way. If the tank becomes empty, and the dam is not empty, the rule would become active and start the tank transfer program. As program 2 is now active, and it is the hold sensor input for the irrigation program, the irrigation program will hold for the duration of the tank transfer program. When the tank transfer program completes, it will become idle, and the irrigation program will resume operation.

Case Example 2, Nested Rules. Three sensors are connected to inputs on the front panel from weather monitoring instruments. Sensor 1 closes when temperature reaches a set point, Sensor 2 closes when the wind reaches a

certain velocity, and Sensor 3 closes when the soil moisture reaches a critically low threshold. We want to set up a set of rules to irrigate a heat program if the temperature is high, but it is not too

windy. However, if the soil moisture is critically low, we want to irrigate irrespective of the temperature or wind conditions.

In this scenario, Rule 1 would be "If Sensor 1 IS True AND Sensor 2 IS False". Rule 2 would be "If Rule 1 IS True OR Sensor 3 IS True, START Heat Program"

This will cause the Heat Program to start if it is hot and not windy, or the soil moisture is low.

Flow Meters

14.4.1 Overview and Operation

The Micro-Master Touch supports up to thirty two independent aggregate flow meters. Flow meters can use any one of the main screen panel switch inputs as the pulse input and supports flow meters that provide 1 or more pulses per litre, 10 litres, 100 litres or kilolitres.

Each flow meter can be named and can be enabled or disabled without modifying the inputs.

Micro-Master Touch User Guide

Flow Meter Operation

When a flow meter is enabled, it is always monitoring the allocated input to calculate the current flow rate. If the flow meter detects flow, the flow meter is active. If the detected flow exceeds the adjustable trigger value, the flow meter is triggered. When the current flow rate falls below the trigger value, the flow meter becomes active, or untriggered. When the current flow rate becomes zero, the flow meter is idle.

The flow meter uses an average, limits and time to calculate the current flow rate. When a pulse is received on the allocated input, the flow meter calculates the exact flow rate. If this flow rate is within the limits specified, the flow is averaged over the number of samples specified. This smoothes small changes in the period between pulses. If the exact flow rate is outside the limits specified, the current flow rate is set immediately to the new value. This may occur at a program's shift/group change, or when programs start. When the flow stops, no more pulses will be received. The flow meter calculates a decreasing current flow rate based on the time elapsed since the last pulse occurred. When the elapsed time increases to a value greater than 5 times the last pulse period, the current flow is set to zero. Using the average, limits and time to calculate the current flow rate produces a flow rate measurement that is responsive to large changes in flow, without excessive fluctuations in the displayed flow during flows of relative uniformity.

The flow meter operation is shown in Figure 63.

Idle Active

Current flow > 0

Current flow = 0

Triggered

Current flow > trigger value

Current flow < trigger value

Figure 63 - Flow Meter Operation Schematic

Flow Meter Parameters

Flow Meter Units

Flow units for a flow meter can be 'Litres', 'Litres x 10', 'Litres x 100', 'Kilolitres'.

Calibration

The calibration for a Flow Meter depends on the type of Flow Meter attached to the controller. For a pulse Flow Meter, the calibration is defined as the number of pulses for each unit of volume, and is specified by the Flow Meter manufacturer. For an 4-20mA Flow Meter the calibration is defined as the number of units of flow at 20mA. The number of pulses per unit flow can be set to any value up to 255. The total flow is updated every pulse by an amount calculated by units/calibration.

For example, if a pulse flow meter has a specified output of 1 pulse per kilolitre, the Flow Meter Units should be set to 'Kilolitres', and the Flow Meter Calibration should be set to 1.

Note that it is possible to mix calibration units between the flow meter and the controller. For example, if a pulse Flow Meter has a specified output of 1 pulse per 100 litres, the Flow Meter Units could be set to 'Kilolitres', and the Flow Meter Calibration could be set to 10. This may assist in setting runtime units for volumetric programs.

Micro-Master Touch User Guide

Average and Limit

Sudden changes in the flow rate and closely spaced pulses can cause wide variations in the calculated flow rate.

Averaging the flow over a number of samples reduces the large variations. Together with the average setting, the limit value affects the way the calculated flow rate is determined. If the flow just calculated is outside the limits specified, the current flow rate is updated immediately to the new value, without averaging.

Together, the flow meter uses the average, limit and time to calculate the current flow.

Trigger Value

The setting adjusts the flow rate (in l/m) at which the flow meter will become triggered.

Allocated Flow Meter

Any switch input on the main screen panel or digital input module in an Expansion Module position can be selected as the input for the flow meter.

Update Rate

This setting only affects flow meters using a digital sensor as an input. Flow Meters using a switch input on the main screen are updated every second and pulse. This setting adjusts the period of time between updates to the calculated flow rate.

Total Flow and Current Flow Rate

The total and current items show the real time total flow and current flow rate for the flow meter. They are updated every second for any change. These values are shown on the edit screen for quick reference and ease of operation.

Note that the total flow and current flow rate use the current saved values for the flow meter. For example, if the calibration value is changed, the change will not be reflected in the total flow or current flow rate until the accept button is pressed.

14.4.3 Flow Meter Edit

The Flow Meter Edit screen is displayed by pressing the icon on the Flow Meter List screen.

Figure 65 - Flow Meter Edit

In the example screen shown in Figure 65, the Treelot flow meter is showing 122 litres per minute, and has a total flow of 1410 litres. The calibration of the flow meter is 1 pulse per 10 litres, and the flow is averaged over three samples. The +/-20% limits define a variation that could be expected during normal operation. A measured flow more than 20% from the last flow value is assumed to be a changed flow and is set as the current flow. If the flow increases above 1700 litres per minute, the flow meter becomes triggered, and could be used as a trigger to stop irrigation.

Flow Meter Name

Each Flow Meter can be assigned a name. Names are limited to 20 characters. Selecting the name button and clicking Edit will display the Text Edit screen.

Flow Meter Units

Shows the flow units for the flow meter. Selecting the button and clicking Edit will cycle the units through 'Litres', 'Litresx10', 'Litresx100', 'Kilolitres'.

Calibration

Shows the calibration, or number of pulses per unit, for the flow meter. Selecting the calibration button and clicking Edit will display the Number Edit screen.

Average

This setting adjusts the number of samples over which the flow meter averages the current flow. Selecting the average button and clicking Edit will display the Number Edit screen.
