About the Zenith 140

The Zenith 140 is a state-of-the-art pump, and level controller, that provides advanced operating routines suitable for an extremely wide variety of applications. The system combines premium specification with high performance even in the most arduous applications where high turbulence and foam or froth is present.

Functional Description

The Zenith 140 level and pump controller is a highly developed ultrasonic level measurement system which provides non-contacting sophisticated pump and level control routines suitable for an extremely wide variety of applications.
Easy calibration and maintenance free “fit and forget” performance mean that you can install the Zenith 140 pump controller rapidly and with confidence. Six user-definable relays with adjustable, individual on and off points, seven user-definable digital inputs, isolated mA output, RS 232 and intelligent performance logging software features provide the user with a superior pump management system and comprehensive level measurement information.
The Zenith 140 operates on the principle of timing the echo received from a measured pulse of sound transmitted in air and utilises the unique DATEM software (Digital Adaptive Tracking of Echo Movement). This is an entirely new digital mapping technique developed especially for the Pulsar Ultra range.
Page 11
11
It gives the system the edge when identifying the “true target level” in the face of competing echoes from pipes, pumps or other obstructions. When coupled with the powerful, long range abilities of a dB transducer and radar range, the Zenith 140 level and pump controller has no equal.
The Zenith 140 can measure from 0 to 131 feet (40m) from the face of the transducer to the surface being monitored, dependent on the transducer used.
The Zenith 140 can show level, space, distance, on the display. The relays can be programmed to activate alarms, pump starters, or other control equipment. In addition, the digital inputs can be used to modify pump and control regimes to optimise performance. There is an isolated 4-20 mA output that can be connected to a chart recorder or PLC, to monitor level, space or distance, independently from that shown on the display. There is an RS232 port, so that the Zenith 140 can be operated remotely by a PC or other equipment.
The Zenith 140 is programmed by the built-in keypad or by PC via the RS 232 Serial Interface (optional). All the parameters are stored in non-volatile memory, so are retained in the event of power interruption. A second backup copy of all parameters can also be retained in the Zenith 140, in case a previous set of parameters needs to be restored.

CHAPTER 2 ZENITH 140 INSTALLATION

Unpacking

Power Supply Requirements

The Zenith 140 can operate from AC supply or from a DC battery and is designed for use in temperatures between -4ºF to +140ºF (-20ºC to +50ºC). The AC is 115V +5% / -10% 50/60Hz. The DC is 18-30V. In all cases the Zenith 140 will typically consume 6W of power, with a maximum of 10W. If Zenith has both an AC and DC supply available then the AC supply source will be automatically sensed and used, should the AC supply be removed for any reason then the DC supply will take over.
The AC and DC wiring should be completed using either 16 – 14AWG (1.5–
2.5mm2) stranded or 16 – 14AWG (1.5–4mm2) solid wire, with all terminals being tightened to 4.5in. lbs. (0.5Nm).
An external supply isolator/circuit breaker (AC or DC) must be fitted near to the unit and labelled to identify the instrument to which it refers.
Important Information
All shipping cartons should be opened carefully. When using a box cutter, do not plunge the blade deeply into the box, as it could potentially cut or scratch equipment components. Carefully remove equipment from each carton, checking it against the packing list before discarding any packing material. If there is any shortage or obvious shipping damage to the equipment, report it immediately to Pulsar Process Measurement Limited.

When using 2 core screened extension cable, the Black and Green wires of the transducer should be connected to the screen of the extension cable, which in turn should be connected to the relevant 0 volts terminal (Terminal 30 or 33).
When installing a transducer in a hazardous area use an approved transducer suitable for the proposed application as detailed below:
FM
For EEx m (Zone 1) applications a transducer certified to FM Class I Div 1 Group A, B, C & D, ClassII Div 1 Group E, F & G, Class III is used, and must
be supplied via a 1500A breaking fuse, which is fitted as standard to the Zenith 140.
Restrictions do not use in the presence of these groups of Chemicals, Aliphatic Hydrocarbons, Ketones or Esters
For EEx ia (I.S.) a transducer certified to FM Class I Div 1 Group A, B, C & D, ClassII Div 1 Group E, F & G is used, which must be connected to the Zenith 140 via an external Zener barrier.

ATEX

For EEx m (Zone 1) applications a transducer certified to Sira 02ATEX5104X is used, and must be supplied via a 4000A breaking fuse,
which is fitted as standard to the Zenith 140. For EEx ia (Zone 0) a transducer certified to Sira 02ATEX2103X is used,
which must be connected to the Zenith 140 via an external Zener barrier.
See transducer label for certification details.
Page 23
23
Single Transducer mode is used to measure space, level, distance or volume and the transducer should be connected to Transducer 1 input terminals.
Dual Transducer mode is used to measure Differential and Average. For Differential, the upstream transducer should be connected to Transducer 1 input terminal and the downstream transducer to Transducer 2 input
terminal. In cases where the Zenith is required to measure Average, then transducers can be connected to either one.

Relay Outputs

The six relays can be programmed for a variety of alarms, pump control, or other process functions. The relay contacts are all rated at 5A at 115V AC.
Wiring should be completed by using suitable cable, to meet the specified 115V AC 5A contact rating, up to maximum size of 14AWG.
All connections should be such that the short circuit capacity of the circuits to which they are connected, is limited by fuses rated so that they do not exceed the relay rating.

Current Output

This is an isolated (floating) mA output (to 150 V), of 4 - 20mA or 0 - 20mA, and the load should not exceed 500 .
Important Information
Please note that if the output of the ultrasonic transducers used with the Zenith 140 are capable of emitting sound pressure levels more than 85dBA (above a
reference sound pressure level of 20µPA), then the Zenith 140 must be located remote from the transducer such that a sound pressure level of 85dBA is not exceeded when standing at the Zenith 140 in the operator’s position.

Important Information
If the equipment is installed or used in a manner not specified in this manual, then the protection provided by the equipment may be impaired.
Important Information
The rear metal case of the fascia unit must be connected to earth via the earthing stud located on the rear of the unit, see drawing above, using wiring to meet local requirements.
Before applying AC power (mains), make sure the supply is 115V AC. Never operate the Zenith 140 with terminal access exposed. An external switch or circuit breaker should be installed near to the Zenith
to allow the supply to be removed during installation and maintenance. In addition, the relay contacts should also have a means of isolating them from the Zenith.
Interconnecting cables must be adequately insulated in accordance with local regulations. Strip back 30 mm of the outer insulation of the cable. Strip 5 mm of insulation from the end of each conductor. Twist all exposed strands of the conductor together. Insert the stripped conductor into the terminal block as far as it will go and tighten the terminal block screw. Ensure that all strands are firmly clamped in the terminal block and that there is no excess bare conductor showing, and no stray strands.

Important Information
The unique DATEM software comes into operation as soon as power is applied and is designed to monitor a moving level or target with the transducer in a fixed position.
If, after any period of use, it should become necessary to move the transducer, for any reason, from its original operating position, switch off the Zenith, before proceeding, in order to prevent any undesirable updates to the DATEM trace. If after moving the transducer the reading is not as expected, please refer to Chapter 6 Troubleshooting.

CHAPTER 3 HOW TO USE YOUR ZENITH 140

Operating the Controls

Display

The display provides information on the current mode of operation, and status of the remote communication. Whilst in the Run Mode it will display the current level reading and its units of measure, along with status messages with regards to the Transducer, Echo reception and Fail-Safe Mode. Additionally, it can be programmed to provide status messages on alarms, pumps etc. When in the Program mode the display is used to read information on the Menu System, Parameter Number and parameter details and values, which can be entered. During Test Mode, the display is used to monitor the simulated level. A bar graph is also provided which will provide a visual reading of the level, in percentage of span.

at.
There are two main operating modes for your Zenith 140, Run Mode and Program Mode. There is also a Test Mode, used for checking the set-up. All modes are now described.

Run Mode

This mode is used once the Zenith 140 has been set up in program mode. It is also the default mode that the unit reverts to when it resumes operation after a power failure.
When the Zenith 140 is switched on for the first time, it will display, in metres, the distance from the transducer face to the target. All relays by default are switched off.
After programming is complete, any relays that are set will operate when the level reaches the relevant setpoint, and the LED’s will change colour (unless specifically switched off).
Page 31
31

Program Mode

This mode is used to set up the Zenith 140 or change information already set. You must use either the built-in keypad (standard) or, alternatively the unit can be set up with a PC via the RS232 Serial Interface.
Entering a value for each of the parameters that are relevant to your application provides all the programming information.

How to Access Program Mode

To enter program mode on the Zenith 140, you simply enter the passcode, via the keypad, followed by the ENTER key. The default passcode is 1997, so you would press the following:

There are two means of editing parameters, directly or using the menu system. Each is now described.

Using the Menu System

The menu system has been designed to make the changing of parameters very simple. There are two levels of menu: Main Menu and Sub Menu.
On the display, there is a line of text that displays the menu system. Pressing the arrow keys scrolls the display between the top-level menu items, (as the example shown below, starting at Quick Setup).
As you press the cursor keys to scroll left and right between these, you can press ENTER at any time, to select the desired menu heading, and take you to the sub-menu.
Each of these options, along with their sub-menus, are described later in this manual. When you move down into the sub-menu, you can scroll round using the arrow keys, press ENTER to go to the required section of parameters.
Once you have reached the relevant section, scroll through the parameters, and enter the necessary information. To enter the information, use the
numeric keys and then press ENTER, you will then see the message “Saved!”
If you press CANCEL, then the change you made will not be saved, and the message “Unchanged!!” will be displayed.
When you have finished, press CANCEL to go back to the previous level. When you have reached the top level, then the Zenith will ask for confirmation before allowing you to go back into run mode. This is done by pressing ENTER at the display prompt.

Directly Editing Parameters

If you already know the number of the parameter, that you wish to look at or edit, simply type the number in at any time while you are in the menu system. Thus, if you are in either the menu or sub-menu level by pressing a numeric key, you can enter the parameter number directly and jump straight there. You cannot type a parameter number whilst at parameter level, only at one of the two menu levels.
When you are at a parameter, the text line rotates automatically displaying the parameter name, number, the applicable units, and the maximum and minimum figure you can enter. The top line shows the value you are setting.
Once you have accessed a parameter, you can either just look at it, or change it.
Once a parameter has been changed, press ‘ENTER’ and you will see the
message “Saved!”. If you press ‘CANCEL’, then the change you made will not be saved, and the message “Unchanged!!” will be displayed.
You can jump straight to the last parameter you edited, by pressing ‘+/-’ when you first enter program mode.
Important Information
You can tell which part of the menu system you are in, as the up/down level indicators, (arrows) next to the bar graph will indicate as follows:
• Top level menu: Down arrow on, to indicate you can move down.
• Sub-menu: Up and Down arrows on, to indicate you can move up to the top
level, and down to parameter level.
• Parameter Level: Up arrow on, to indicate you can move up to sub-menu
level.
• Parameter Editing: No arrows on.

Test Mode

Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard
simulation) or not (soft simulation), but the LED’s will always change colour
as programmed, and the mA output will change in accordance to the chosen mode of operation. If you wish to test the logic of the system that the relays
are connected to then select hard simulation, but if you do not wish to change the relay state, then select a soft simulation.
There are two simulation modes, automatic and manual. Automatic simulation will move the level up and down between empty level or the pre­determined Start Level (P983) and Pump/Control relay switch points, if you wish to change the direction of the level movement e.g. to go beyond relay setpoints, this can be done by using the arrow keys. In manual simulation, using the arrow keys will allow you to move the level up and down as required.
To enter simulation, first go to program mode. Using the menu system, select menu item ‘Test’, then sub-menu item ‘Simulation’. Simply change the value of the parameter P980 to one of the following:
1= Manual soft simulation 2= Automatic soft simulation 3= Manual hard simulation 4= Automatic hard simulation
To return to program mode, press ‘CANCEL’ and test mode will end. When in manual simulation, by default test mode will move the level by
0.328 feet steps. Altering the increment (P981) will change this value. In automatic mode, the rate at which the level moves up and down is set by
the increment (P981 in feet, and the rate (P982) in minutes, which can be changed to make the level move up and down faster. E.g., if increment (P981) is set for 0.328 feet and rate (P982) is set to 1 min then the level will increase or decrease at a rate of 0.328 ft/min. To make the simulated level move slower, decrease the value in increment (P981) or increase the value in rate (P982). To make the simulated level move faster, increase the value in increment (P981) or decrease the value in rate (P982).
Page 37
37

Using the Serial Interface

The RS232 serial interface is used to communicate between the Zenith and a PC using the optional Ultra PC and other associated Pulsar software packages, to obtain information such as data logging and view echo traces upload, download and save parameter files. In addition, it can also be used to control or obtain information using a standard PC or other computer base equipment. To do so, the settings for control are as follows: baud rate 19,200, 8 data bits, no parity, 1 stop bit.
The device should be connected as shown in Chapter 2 Zenith
140 Installation.
To use the device remotely, you need to log on to start, and log off when finished. When logged on, the Zenith will show ‘Remote ON’ on the display, and “Communicator OFF” when logged off.
All commands should be followed by a carriage return. When logged on, the unit will respond either OK (or a value) if the command is accepted, or NO if it is not.
To log on, send the command /ACCESS:pppp where pppp is the passcode (P922). To log off, send the command /ACCESS:OFF To read a parameter value, send the command /Pxxx where xxx is the parameter you wish to read, and the Zenith 140 will
respond with the parameter value. To set a parameter, send the command /Pxxx:yy where xxx is the parameter number, and yy is the value you wish to
set it to.
Page 38
ZENITH 140 UL INSTRUCTION MANUAL

Other commands you can use are:
/DISTANCE (shows current distance)
/LEVEL (shows current level)
/SPACE (shows current space)
/RATE (shows current rate)
/VOLUME (shows current volume)
/TEMP (shows current temperature)
/CURRENTOUT1 (show the mA output 1 value)
/CURRENTOUT2 (show the mA output 2 value)
/BACKUP1 (take backup of parameters to area 1)
/BACKUP2 (take backup of parameters to area 2)
/RESTORE1 (restore parameters from area 1)
/RESTORE2 (restore parameters from area 2)
Please consult Pulsar Measurement or contact your local Pulsar representative for further details and a full list of available commands.

Parameter Defaults

When you first switch the Zenith 140 on, it will be reading the distance from the face of the transducer to the surface. It will be indicating in metres, as shown on the display. All relays are set OFF.
The date (P931) and time (P932) in the Zenith 140 were set at the factory, but may need checking, and amending if, for example the application is in a time zone other than GMT, see relevant parameter listing for full details.
In some applications, it is easier to empty the vessel, take a reading from the Zenith 140 for distance and then setup the empty level to this figure.
Once you are satisfied with the installation, and Zenith 140 is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with programming, for the intended application. It is sensible to program all the required parameters at the same time. The system will be then set-up.
Note: The span is automatically calculated from the empty level, so the empty level should be entered first.
Factory Defaults
When first installing the Zenith, or subsequently moving or using the unit on a new application, before proceeding to program the unit for its intended application it is recommended that you ensure that all parameters are at their default values by completing a Factory Default P930, as described in the relevant unit type parameter guide.

Choose Your Application

There are four categories of application, which are all described at the end of this chapter. They are level, pump down (sump control), pump up (reservoir control) or customised, all with the choice of alarms and a number of pumps, dependant on application.
If you want to set-up a basic level monitoring application, as described in the following example 1, then choose 1. You then need to decide the number of alarms required and their function and choose the appropriate options.
If you want to set-up a pump down (sump control) application, as described in the following example 2, then choose 2. You then need to decide the
number of pumps required the pump duty and any requirement for alarms and choose the appropriate options.
If you want to set-up a pump up (reservoir control) application, then choose
3. You then need to decide the number of pumps required the pump duty, and any requirement for alarms, and choose the appropriate options.
In certain cases, the Quick Setup Menu has been customised for customer specific applications, to choose one of these options press 4 and select the appropriate customised application and enter the details required as prompted.
Once you have chosen your application you will be asked a series of questions which are answered by choosing the appropriate option as detailed in the flow charts that follow. Once all the questions have been answered you will be prompted to provide further information, as detailed in the tables that follow, to complete the programming of the unit.

Example 1 Level Monitoring with Alarms

A vessel, containing liquid that has a variation in level that is to be monitored, with a high-level alarm set on Relay 1 and low-level alarm set on Relay 2.
In this example, when the level rises to 8.5 feet, relay 1 will come on until the level drops to 8 feet when it will turn off. If the level drops to 1 feet, then relay 2 will come on until it rises 1.5 feet when it will turn off.
The display will show the level in the tank.
The mA output will be representative of level where 4mA = empty level (0%) and 20mA = 10 feet (100%).

Example 2 Sump Control (pump down)

A sump is typically used to temporarily hold water or effluent, and when the level reaches a specific point, the sump is pumped down, with the fluid being transferred to another process.
In this example, there are two pumps, which will be set to alternate duty assist, so they come on alternately. Pump 1 is to be set to relay 1, pump 2 to relay 2, and the high-level alarm to relay 3.
This will operate as follows. During normal operation, pump 1 will come on at 3 feet and pump down to 2 feet. The setpoints are then shifted to pump 2, which will come on first next time. During peak periods, when pump 1 cannot cope, pump 1 will come on at 3 feet, pump 2 will come on at 5 feet, and pump down to 2 feet. The setpoints are then shifted to pump 2, which will come on first next time.
If neither pump can cope, and the level rises to 8.5 feet, then the alarm relay (relay 3) will come on and go off when the level falls to 8 feet. This will indicate insufficient capacity of the pumps. The display will show the level in

Example 2 Sump Control (pump up)

A reservoir is typically used to temporarily hold liquid, and when the level reaches a specific low point, the reservoir is pumped up.
In this example, there are two pumps, which will be set to alternate duty assist, so they come on alternately. Pump 1 is to be set to relay 1, pump 2 to relay 2, and the high-level alarm to relay 3.
This will operate as follows. During normal operation, pump 1 will come on at 3 feet and pump down to 2 feet. The setpoints are then shifted to pump 2, which will come on first next time. During peak periods, when pump 1 cannot cope, pump 1 will come on at 3 feet, pump 2 will come on at 5 feet, and pump down to 2 feet. The setpoints are then shifted to pump 2, which will come on first next time.
If neither pump can cope, and the level rises to 8.5 feet, then the alarm relay (relay 3) will come on and go off when the level falls to 8 feet. This will indicate insufficient capacity of the pumps. The display will show the level in the sump and the mA output will be representative of level where 4mA = empty level (0%) and 20mA = 10 feet (100%).

Dimensions

P104 Measurement Units

This parameter sets the units you want to use for programming and display.
OPTION
DESCRIPTION
1 = metres
All units of measurement are Metres
2 = cm
All units of measurement are Centimetres
3 = mm
All units of measurement are Millimetres
4 = feet (Default)
All units of measurement are Feet
5 = inches
All units of measurement are Inches

P105 Empty Level

This parameter is to be set to the maximum distance from the face of the transducer to the empty point, in P104 Measurement Units. Note this value affects span as well, (see the following important information notices), so should be set before span.

P106 Span

This parameter should be set to the maximum distance from the Empty Level (P105) to the maximum material level. It is automatically set to be
equal to the Empty Level (P105) less the Near Blanking distance (P107) when you set the empty level.
Important Notice
When changing the Empty Distance (P105) you can also recalculate the values for the Span so that it equals the empty distance (P105) minus Near Blanking (P107) and the Relay Setpoints, so that they remain at the same percentage values of the empty distance as they were before you changed the empty distance (P105). You will be asked the question
“Recalculate Span?” if you choose yes (enter 1), then the span will be
recalculated. Any other answer will leave the span at its original value.
You will then be asked if you want to “Recalculate Setpoints?”, if you
choose yes (enter 1), then all Relay Setpoints will be recalculated as a percentage of the new empty distance. Any other answer will leave the setpoints at their original values.
Important Notice

When using the dB Mach 3 the empty distance is measured from the end of the horn to the empty point in P104 Measurement Units.

*The signal emanates from the curved face of the radar, but for the purposes of measurement it is taken from the drip shield.

P108 Far Blanking Distance

This is the distance (as a percentage of the empty level P105) beyond the empty point that the unit will be able to measure, and by default is pre-set to 20% of the empty level.
If the surface being monitored can be extended beyond the empty level (P105) then the far blanking distance can be increased to a max. of 100% of the empty level, provided it does not exceed the max range of the transducer being used. This parameter is always entered as a % of the empty level.

mA Input

The 4-20 mA (Auxiliary) input is available as an option (Consult Pulsar for details of availability), and can be used to replace the transducer for applications where an ultrasonic transducer cannot be used.

P119 mA Status

If P101 (Xducer) = 1 (Auxiliary)
This indicates the status of the Auxiliary input if selected
OPTION
DESCRIPTION
1 = mA OK (Default)
mA Input present and functioning correctly
1 = mA Open
No input (device) is being detected
2 = mA Short
Input is indicating a fault condition

P120 Low mA in

This parameter sets the current input figure that is used to represent empty when using the optional current input, instead of an ultrasonic transducer.
Default = 4ma

P121 High mA in

This parameter sets the current input figure that is used to represent span when using the optional current input, instead of an ultrasonic transducer.
Default= 20mA

P122 Low Level in.

This parameter sets the distance to empty point when using the optional current input, (Aux. input) instead of an ultrasonic transducer.
Default = 0.00 feet

P123 High Level in

This parameter sets the distance that is full (span) when using the optional current input, (Aux. input) instead of an ultrasonic transducer.
Default = 19.685 feet

P124 Low mA Trim

This parameter allows you to “calibrate” the Zenith to the Low mA Input from the device being used. If the expected low value, from the device connected to the mA Input, is not displayed, then you can trim it using this parameter.

P125 High mA Trim

This parameter allows you to “calibrate” the Zenith to the High mA Input from the device being used. If the expected high value, from the device connected to the mA Input, is not displayed, then you can trim it using this parameter.
Important Notice
When using the auxiliary input, all settings relating to measurement should be entered in relation to level i.e., zero (empty) to 100% (full) and not distance. This also means that the device you are connecting should provide an input that will change with level.

Pumps

P210, 220, 230, 240, 250, 260= 2 (Pump)
When a relay is being used for a pump function, the second parameter determines the pump duty that will be used to determine the operating cycle.

P211, 221, 231, 241, 251, 261 – Relay Function

This parameter defines which pump duty the relay should respond to as follows:
PUMP DUTY
DESCRIPTION
0 = Off (Default)
Relay is always de-energised
1 = Fixed duty assist
All pumps are used to assist each other (run at the same time) and each pump has its own setpoints. (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264).
2 = Fixed duty backup
If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped, and another pump shall take over. Each pump has its own setpoints. (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264).
3 = Alternate duty assist
All pumps are used to assist each other (run at the same time) and each pump has its own setpoints, (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264). but each time all pumps have stopped, then the setpoints are sequentially rotated between the pumps to ensure equal pump use.
4 = Alternate duty backup
If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped, and another pump shall take over. Each pump has its own setpoints, (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264). but each time all pumps have stopped, then the setpoints are sequentially rotated between the pumps to ensure equal pump use.
Page 85
85
PUMP DUTY
DESCRIPTION
5 = Duty backup and assist
First pump comes on, if it cannot cope, it goes off and next pump comes on (duty backup). This continues until the last pump comes on and if it cannot cope the first pump comes back on to assist the last pump (duty assist) if the level continues to rise all other pumps will come on (assist) in turn until the level decreases to the pump off points. Each pump has its own setpoints, (P213, 223, 233, 243, 253 & P214, 224, 234, 244, 254, 264).
6 = Service ratio duty assist
All pumps are used to assist each other (run at the same time) and each pump has its own setpoints (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264). And a service ratio setting. The third setpoint (P215, 225, 235, 245, 255, 265) is used to set the service ratio. Each time a pump is required to start then the pump with the least running hours (with respect to the service ratio) is started (i.e. the setpoints are re­assigned accordingly). For example, if two pumps A and B have the service ratio set to 2 and 1 respectively, then pump A will operate for twice as many hours as pump B.
Page 86
ZENITH 140 UL INSTRUCTION MANUAL
86
PUMP DUTY
DESCRIPTION
7 = Service ratio duty backup
The first pump switched on is the first pump to be switched off, regardless of the set points, so the setpoints are dynamically changed to enable this. If a pump fails to meet the demand (due to malfunction, intake blockage and so on), then it is stopped, and another pump shall take over. Each time a pump is required to start then the pump with the least running hours (with respect to the service ratio) is started (i.e. the setpoints are re-assigned accordingly). Each pump has its own setpoints (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264). The third setpoint (P215, 225, 235, 245, 255, 265) is used to set the service ratio. E.g., if two pumps A and B have the service ratio set to 2 and 1 respectively, then pump A will operate for twice as many hours as pump B.
8 = First On First Off Alternate duty assist
The first pump switched on is the first pump to be switched off, etc. regardless of the set points, so the setpoints are dynamically changed to enable this.
9 = Service Ratio Standby
When a service ratio duty is being used, on all other pumps in use, the standby pump can be started on a ratio basis only, when it will assume the setpoints of the next pump to start. The third setpoint (P215, 225, 235, 245, 255, 265) is used to set the service ratio.
10 = Two Pump Sets
There are four pumps. Two rotate their start-up sequence with each other. If the two pumps cannot keep up, the level rise to the setpoints of the other two pumps which take over and rotate their sequence with each other.
Important Notice
The pumps are started and stopped at the “ON” and “OFF” setpoints. To pump down (reduce level) then set “ON” higher than “OFF”. To pump up (increase level) then set “ON” lower than “OFF”.
Page 87
87
The third parameter for each relay determines the pump group. You can have two groups of pumps, and all similar duties within that group will operate together.

P212, 222, 232, 242, 252, 262 – Relay Pump Group

By default, all pump groups are set to 1, but if you want to have another group, then set this parameter to 2, for each pump relay that should operate together as part of a second group.
The fourth parameter and the fifth parameter for each relay set the pump “ON” and “OFF” points, which are entered in Measurement units P104. For
pump down the “ON” is set higher than “OFF”. For pump up then “ON” is
set lower than “OFF”. See the appropriate pump duty, function table (P212, 222, 232, 242, 252, 262) for further information.

P213, 223, 233, 243, 253, 263 – Relay Setpoint 1

This parameter determines the ‘ON’ point of the pump.

P214, 224, 234, 244, 254, 264 – Relay Setpoint 2

This parameter determines the ‘OFF’ point of the pump.
The sixth parameter will determine the service ratio that will be used to switch the pump, when pump duty selected is a Service Ratio duty.
P210, 220, 230, 240, 250 = 6, 7 or 9 (Service ratio)

P215, 225, 235, 245, 255, 265 – Relay Setpoint 3

This parameter determines the Service Ratio in values of %. See the appropriate pump duty function, table (P211, 221, 231, 241, 251, 261), for further information.

P219, 229, 239, 249, 259, 269 – Relay Max Rate

This parameter will allow a pump to be switched at a pre-determined Rate of change of Level, irrespective of the “ON” level setpoint P213, 223, 233,
243, 253, 263. Once a pump relay has been switched “ON” by the pre­determined Rate of Change, it will remain energised until the level reaches the “OFF” level setpoint P214, 224, 234, 244, 254, 264.
Max. Rate is entered in Measurement Units (P104) per minute and can be entered as either positive (increasing level) or negative (decreasing level) values.

Control

P210, 220, 230, 240, 250, 260 = 3 (Control)
When a relay is being set as a control relay, the second parameter that will be displayed in the menu determines its function.
P211, P221, P231, 241, 251, 261 - Relay Function,
This function allows the relay to be assigned to specific control functions and mainly work in relation to time.
OPTIONS
DESCRIPTION
0 = Off (Default)
Relay is always de-energised
1 = Time
Relay will energise “ON” after the Cycle time that is set in Relay Setpoint 2 (P214, 224, 234). And turns “OFF”, de-
energises, after the On-Time Period that is set in Relay Setpoint 1 (P213, 223, 233, 243, 253)
2 = Storm
Relay will energise “ON” when storm conditions are in effect and, de-energise “OFF” when storm conditions cease. Two setpoints are required, Upper Storm “ON”, (P213, 223, 233, 243, 253, 263) and Lower Storm, “OFF” (P214, 224, 234, 244, 254, 264). This allows the relay to be used to activate a device as a result of high levels such as a storm condition e.g. opening a gate valve to divert storm overflow into a holding vessel.
3 = Aeration
Relay will energise “ON” after each Cycle time as set in Relay Setpoint 2 (P214, 224, 234, 244, 254, 264). And turns “OFF”, de-energises, after the set On Time Period as set in Relay Setpoint 1 (P213, 223, 233, 243,253, 263). This can be used to activate a device based upon elapsed time since All Pumps have been “OFF”, such as the introduction of fresh air to reduce gas concentration.

OPTIONS
DESCRIPTION
4 = Flush Valve
Relay will energise “ON” when Flush condition is in effect and goes off when Flush condition is cleared. A relay being used for Flush Valve/Pump must be assigned to one of the main pumps in use. Flush relay Alarm ID (P212, 222, 232, 242, 252, 262) is used to enter the relay number, to which the assigned pump is connected. Flush Valve/Pump relay requires three setpoints. The first set point (P213, 223, 233, 243, 253, 263) determines the Flush Interval, which is the number of main pump cycles that should occur before the Flush Valve/Pump operates. The second setpoint (P214, 224, 234, 244, 254, 264), sets the number of Flush cycles the Flush Valve/Pump will operate for. This means that the Flush Valve will be operated for several main pump starts (Flush Cycles) after which the Flush Valve activity will cease until the Flush Interval comes around again. Setpoint three of the Flush Valve/Pump relay sets the Flush Duration, (P215, 225, 235, 245, 235, 236) this is the duration for Flush
5 = Step Time
Step Time Control allows relays to be used to control a device, such as a motorised valve or gate, in order to maintain the level within two predetermined points. Relays will energise “ON” when Step Time condition is in effect and
de-energises “OFF” when Step Time goes off. One relay will be required to control an increase in level, (‘open’ the device)
and a second relay is required to control a decrease in level, (‘close’ the device). Alarm ID (P212, 222, 232, 242, 252, 262) is used to assign the relay to control either the open or close condition. Step Time Control relay requires three setpoints. The first set point (P213, 223, 233, 243, 253, 263) determines the level, at which the relay is to be activated, (N.B. level setpoint for open relay, increase the level, must be lower than the setpoint for the close relay, decrease the level). The relay will energise “ON” after the Limit time that is set in Relay Setpoint 3 (P215, 225, 235, 245, 255, 265). And turns “OFF”, de-energises, after the Drive Period that is set in Relay Setpoint 2 (P214, 224, 234, 244, 254, 264).

DESCRIPTION
6 = Differential Control
Relay will energise “ON” when a differential condition is in effect and, de-energise “OFF” when the differential conditions cease. Two setpoints are required, Differential
control “ON”, (P213, 223, 233, 243, 253, 263) and Differential control, “OFF” (P214, 224, 234, 244, 254, 264).
This allows the relay to be used to activate a device because of a differential level, between two points e.g. operate a rake on a screen.
The third parameter for each relay determines the assignment or condition of the relay, where required.

Miscellaneous

P210, 220, 230, 240, 250 = 4 (Miscellaneous)
When a relay is set to be a miscellaneous relay, the second parameter determines its function.

P211, 221, 231, 241, 251, 261 – Relay Function

This function allows the relay to work in relation to a clock or a specific event and will be set to activate in relation to Real Time.
OPTIONS
DESCRIPTION
0 = Off (Default)
Relay is always de-energised
1 = Clock
Relay will energise ON at a specified time each day as set in Relay Setpoint 1 (P213, 223, 233, 243, 253, 263). And turns OFF, de-energises, after the specified “On Time” period as set in Relay Setpoint 2 (P214, 224, 234, 244, 254, 264)
2 = Totaliser
Relay will energise ON momentarily each time the specified flow has passed as set in Relay setpoint 1 (P213, 223, 233, 243, 253, 263), this parameter sets the multiplication factor which will be applied to the on­board totaliser (P820) to determine the switch point of the relay. E.g., if the totaliser is set to totalise in cubic metres and the relay is required to provide a closure every 10,000 litres Relay setpoint 1 would be set to 10. Relay setpoint 2 (P214, 224, 234, 244, 254, 264) can be used to select the time the relay will remain closed in seconds.
Important Notice
When using a Relay to control a device at a specified time of day ensure that the Time P932 is set correctly. And if required, enable Daylight Saving for the appropriate time difference P970 – P979.

P214, 224, 234, 244, 254, 264 – Relay Setpoint 2

Relay Setpoints are entered in seconds to set the Time Period that the relay will remain ‘ON’. Default = 0.00 secs.

Pump by Time

When a relay is assigned to Pump by Time the pump will come on (energise) at its normal “ON” level setpoint, and de-energise at its OFF level setpoint or after a predetermined time period, whichever occurs first.
P210, 220, 230, 240, 250, 260 = 5 (Pump by Time) When a relay is being used for a pump by time function, the second
parameter determines the pump duty that will be used to determine the
operating cycle.
Page 95
95
P211, P221, P231, P241, P25, 2611 - Relay Function,
This parameter defines which pump duty the relay should respond to as follows.
PUMP DUTY
DESCRIPTION
0 = Off (Default)
Relay is always de-energised
1 = Fixed duty assist
All pumps are used to assist each other (run at the same time) and each pump has its own setpoints. (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264).
2 = Fixed duty backup
If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped, and another pump shall take over. Each pump has its own setpoints. (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264).
3 = Alternate duty assist
All pumps are used to assist each other (run at the same time) and each pump has its own setpoints, (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264). but each time all pumps have stopped, then the setpoints are sequentially rotated between the pumps to ensure equal pump use.
4= Alternate duty backup
If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped, and another pump shall take over. Each pump has its own setpoints, (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264) but each time all pumps have stopped, then the setpoints are sequentially rotated between the pumps to ensure equal pump use.

PUMP DUTY
DESCRIPTION
5= Duty backup and assist
First pump comes on, if it cannot cope, it goes off and next pump comes on (duty backup). This continues until the last pump comes on and if it cannot cope the first pump comes back on to assist the last pump (duty assist) if the level continues to rise all other pumps will come on (assist) in turn until the level decreases to the pump off points. Each pump has its own setpoints, (P213, 223, 233, 243, 253, 263 & P214, 224, 234, 244, 254, 264).
The third parameter for each relay determines the pump group. You can have two groups of pumps, and all similar duties within that group will operate together.
P212, P222, P232, P242, P252, 262 - Relay Pump Group
By default, all pump groups are set to 1, but if you want to have another group, then set this parameter to 2, for each pump relay that should operate together as part of a second group.
The fourth parameter, and the fifth parameter for each relay set the
pump “ON” and “OFF” points, which are entered in Measurement units P104. For pump down the “ON” is set higher than “OFF”. For pump up then “ON” is set lower than “OFF”. See the appropriate pump duty, function table (P212, 222, 232, 242, 252, 262) for further information.

P213, P223, P233, P243, P253, 263 - Relay Setpoint 1

This parameter determines the “ON” point of the pump.

P214, P224, P234, P244, P254, 264 - Relay Setpoint 2

This parameter determines the “OFF” point for the pump. When a relay is being used for a pump by time function, then the sixth
parameter will determine the maximum time the pump will be allowed to run before it is switched off and the next pump takes over.
Important Notice
The pumps are started and stopped at the “ON” and “OFF” setpoints. To pump down (reduce level) then set “ON” higher than “OFF”. To pump up (increase level) then set “ON” lower than “OFF”.
Page 97
97

P215, P225, P235, P245, P255, 265 - Relay Setpoint 3

This parameter determines the Maximum Time the pump will be allowed to run before being switched “OFF” and is entered in minutes.
The pump will switch off either at its “OFF” level Relay Setpoint 2 (P214, 224, 234, 244, 254) or its Maximum Run Time Relay Setpoint 3 (P215, 225, 235, 245, 255), whichever occurs first.

P219, P229, P239, P249, P259, 269 - Relay Max.Rate

This parameter will allow a pump or general control relay to be switched at a pre-determined Rate of change of Level, irrespective of the “ON” level setpoint P213, 223, 233, 243, 253, 263. Once a pump or general control relay
has been switched “ON” by the pre-determined Rate of Change, it will remain energised until the level reaches the “OFF” level setpoint P214, 224,
234, 244, 254, 264. Max. Rate is entered in Measurement Units (P104) per minute and can be
entered as either positive (increasing level) or negative (decreasing level) values.

Common Relay parameters

P216, 226, 236, 246, 256, 266 – Relay Allocation

This parameter determines which input the relay will act on. You can set it to the transducer (default), or the optional auxiliary (current) input, or an average of the two. In most cases, this will not need to be changed from the default.

P218, P228, P238, P248, P258, 268 - Relay Fail Safe

Your Zenith has a general fail-safe parameter P808. However, this can be overridden so that each individual relay has its own independent failsafe mode. This parameter determines what the relay will do in the event of the Failsafe Time (P809) expiring.
OPTIONS
DESCRIPTION
0 = Default
Relay assumes system default mode P808
1 = Hold
Relay remains in its current state
2 = De-energise

below their normal “OFF” point, to discharge any sediment that may have
settled at the bottom of the vessel.

P349 Prime Level

Sets the required level to ensure pumps are fully primed after a pump run
on has occurred. Following a pump run on, any pump, whose “ON” point is below the Prime Level will be held “OFF” until the Prime Level has been
exceeded.

P350 Run Interval

Set required time period, in hours, at which pump run on should occur.

P351 Run Duration

This parameter sets the length of time, in seconds, that pumps will run on for, it should be noted that only one run on is allowed per Run Interval.

Starting

This feature is used to reduce the effects of power surges, caused by switching of pumps, in the following instances, (P352) Power surge (mains or hydraulic) that is generated when multiple pumps are started simultaneously, (P353) Power resumption following a power failure.

P352 Start Delay

Set the required time period, in seconds, that should elapse between pumps starting. Default = 10 seconds.
