RD-64X Operators Manual

1. Introduction

1.1 Description

The RD-64X remote display is a multi-channel gas detection system designed to serve as a read only monitor for a gas detection controller. It is configurable for up to 64 channels and interfaces with Modbus™ RS-485 control systems. The RD-64X remote display utilizes a non-intrusive magnetic interface and displays real time channel information on a backlit LCD. Display information includes the channel number, gas concentration, device tag (gas type) and alarm/fault status. Each channel provides three alarm levels (Alarm 1, Alarm 2 and Alarm 3) and fault for which the present status can be shown via the front panel LED indicators. Additional features include Alarm Reset, Alarm Silence (Acknowledge) and two banks of four local alarm outputs each. External alarm relays can also be added using Detcon’s RL-4 relay modules, up to two each per bank.

The RD-64X is available in a choice of two enclosures. The first enclosure type is the Model RD-64XN4X which is housed in a NEMA 4X water proof enclosure and has a built in power supply that takes in 110/220VAC and outputs 24VDC. External DC power (11.5-30VDC) can also be provided by the customer to power the remote display if AC power is not available or desired. This unit provides a DIN rail which is used to mount the power supply and terminal blocks. If external alarm relays are used, Detcon’s RL-4 relay modules are required and will need to be mounted in a separate enclosure.

The second enclosure type is the Model RD-64X-N7 which is housed in a NEMA 7 explosion proof enclosure. Due to this enclosure type, the unit’s internal space is limited and cannot support a built in power supply or DIN rail. The unit will need to be powered externally by 11.5-30VDC. AC power (90264VAC) can also be used to power the remote display by using Detcon’s optional AC/DC converter module. If external alarm relays are used, Detcon’s RL-4 relay modules are required and will need to be mounted in a separate enclosure.

1.2 System Operation

The heart of the RD-64X is the non-intrusive magnetic interface with backlit LCD display. The display receives real time data from gas detection controllers using RS-485 Modbus™ RTU protocol. The RD64X includes a primary Modbus™ interface (COMM1 Master) used to receive concentration and status directly from the Modbus™ capable controller (Slave) being monitored. A secondary Modbus™ interface (COMM2 Slave) is also available which is used for communication with another remote display where the RD-64X is seen as a slave device.

Alarm values and fault conditions can be configured to cause an assigned relay output to fire, thus triggering external alarm devices. As gas alarm or fault conditions clear, the assigned relay outputs return to their normal states. Relays can be set-up as Energized/De-Energized, Latching/Non-Latching and Silenceable/Non-Silenceable. The RD-64X remote display also allows for wiring of an external manual switch to act as an Acknowledge/Reset switch.

NOTE: The set-up configuration is fully field-configurable and can be executed by the user in the field. Refer to section 7 System Operation and Configuration. Modifications to the set-up configuration are expected to take place at the customer’s site due to requirement changes and/or system expansions.

2.2 Power and Modbus Connections

The RD-64X-N4X remote display can be powered by either 110/220VAC or 11.5-30VDC. An internal power supply is available for the RD-64X-N4X that converts 110/220VAC to 24VDC (up to .75 Amps) and can power up to four RL-4 relay output modules. Optionally, the RD-64X-N4X remote display can be powered by an external DC power source that meets the input requirements of the unit.

The RD-64X-N4X remote display also includes a primary Modbus™ interface (COMM1 Master) used to receive concentration and status directly from a Modbus™ capable controller (Slave) as well as a secondary Modbus™ interface (COMM2 Slave) which is used for communication with another remote display where the RD-64X-N4X is seen as a slave device.

2.2.1 AC Power

Connect 110/220VAC input wiring to the terminals of the DIN rail mounted terminal block labeled “VAC (L1)”, “NEU (L2)”, and “GROUND” (See Figure 2). The power supply for the RD-64X-N4X is capable of handling AC inputs from 100-240VAC, 45-65Hz without degradation and can power up to four RL-4 relay output modules.

NOTE: The input voltage range must be between 100-240VAC. The power supply used for the RD-64X-N4X remote display should have a common ground with the power supply used for the controller.

2.2.2 DC Power

For optional external DC power input, connect 11.5-30VDC to the terminals of the DIN rail mounted terminal block labeled “24VDC” and “DC Comm” (See Figure 2). This input can be used for primary power or back-up power in the event of an AC power failure. The DC input voltage source should be capable of delivering at least .75 Amps of current to the load (18 Watts @ 24VDC) which will power up to four RL-4 relay output modules.

NOTE: The supply of power should be from an isolated source with over-current protection. The input voltage range must be between 11.5-30VDC. The power supply used for the RD-

64X-N4X remote display should have a common ground with the power supply used for the controller.

2.2.3 Modbus Connections

The serial RS-485 (Modbus™) connection from the controller (Slave) being monitored to the RD-64XN4X remote display (COMM1 Master) is provided to the terminals of the DIN rail mounted terminal block labeled “RS-485 MASTER” (See Figure 3). The serial RS-485 connection labeled “RS-485 SLAVE” is used to connect to another remote display where the RD-64X-N4X will be seen as a slave device in that specific Modbus™ loop. RS-485 connections require 24 AWG, two conductor, shielded, twisted pair cable. Belden P/N 9841 is recommended for a single cable providing serial communication only.

2.3 Local Alarm Outputs

The RD-64X-N4X remote display provides local alarm outputs for up to four alarms (Alarm 1, Alarm 2, Alarm 3 and Fault) for each of its two defined relay banks (See Figure 4). These local alarm outputs can drive relays on custom terminal boards provided by Detcon and are controlled by the remote display based on the configuration and current alarm state of the whole network. They are not intended to drive alarm devices directly, but rather to drive relay coils (interposing relays) which in turn will drive a higher current output. The local alarm outputs are open collector and rated for up to 600mA at 40V.

The local alarm outputs are configured for two separate relay banks (Bank1 and Bank2) and each bank can support up to four alarm outputs. These local alarm outputs will be triggered whenever a corresponding alarm is fired that is configured for the outputs specific bank. For example, if alarm 3 of a particular alarm station configured to Bank2 is triggered, then the local alarm 3 output in Bank2 (A3B2) will also be triggered. The local alarm outputs do not need to be addressed as they are not part of the Modbus™ network. The banks must, however, be assigned to specific channels via the Set Channel RL4/Alarm Station Banks menu in section 7.3.8.

When using interposing relays, the customer must protect the RD-64X-N4X local alarm outputs against the voltage spike that can be over 1000V when the relay is de-energized. This voltage spike will damage the alarm output since it is well over the rated maximum voltage of 40V and will cause the output to fail. A transient protection diode (1N4001 or equivalent) can be placed across the relay coil to mitigate the voltage spike (See Figure 5).

NOTE: External relays used with this circuit must not exceed voltage/current requirements and must have transient protection to minimize the voltage spike when the coil is de-energized.

3.2.1 DC Power

The RD-64X-N7 remote display is generally powered by a DC voltage source which is typically provided by the controller it is interfaced with but can also be provided externally by the customer through another voltage source. The remote display requires 11.5-30VDC to the PWR and GND terminals of connector J7. A transient protection module is provided inside a condulet/J-Box (See Figure 7) to protect the unit from power spikes or overloading. It is strongly recommended to use the transient protection module if no transient protection is provided by the controller or external voltage source. Refer to Figure 9 for wiring if the transient protection module is used. Only one RL-4 relay output module can be supported by the transient protection module. Additional RL-4s will need to be powered separately and have their own separate transient protection.

NOTE: The supply of power should be from an isolated source with over-current protection. The input voltage range must be between 11.5-30VDC. The power supply used for the RD64X-N7 remote display should have a common ground with the power supply used for the controller.

3.2.2 AC Power (Optional)

The RD-64X-N7 remote display can also be AC powered using Detcon’s optional AC/DC converter module which can be installed inside the condulet/J-Box in place of the transient protection module. This module takes an input voltage of 90-264VAC at 50-60Hz and outputs 24VDC. Refer to Figure 10 for wiring if the AC/DC converter module is used. This module is used to power the remote display only. Any RL-4s will need to be powered separately with their own separate transient protection. Only the Modbus™ interface can be shared with RL-4s in this configuration. Connections C and D are straight through connections to be used as needed.

3.2.3 Modbus Connections

The serial RS-485 (Modbus™) connection from the monitored controller (Slave) to the RD-64X-N7 remote display (COMM1 Master) is provided to the A1 and B1 terminals of connector J7. Refer to Figure 9 for wiring if using the provided transient protection module or Figure 10 if using the optional AC/DC converter module. The A2 and B2 terminals of connector J7 are used to connect to another remote display where the RD-64X-N7 will be seen as a slave device. RS-485 connections require 24 AWG, two conductor, shielded, twisted pair cable. Belden P/N 1502P is recommended for a single cable providing serial communication and power. Belden P/N 9841 is recommended for a single cable providing serial communication only.

NOTE: The RD-64X-N7 remote display and the controller should have a common ground.

4. RL-4 Alarm Outputs

4.1 RL4 Relay Outputs

The RD-64X remote display features the capability of adding RL-4 alarm relay modules to control (fire) annunciating devices near the remote display. There are four Form C, Single Pole Double Throw (SPDT), 5 Amp relay contacts in the RL-4 module. Each relay in the module is assigned specifically to one alarm. Relay 1 is assigned to Alarm 1, relay 2 is assign to Alarm 2, relay 3 is assigned to Alarm 3 and relay 4 is assigned to Fault. Connections to the relay contacts of the RL-4 module are shown in Figure 11 and are labeled C (Common), NO (Normally Open) and NC (Normally Closed). Note that the 5 Amp rating of the relay contact should not be exceeded.

Figure 11 Model RL-4 Relay Output Module

The RL-4 module provides contact outputs which are communicated by the remote display to the RL-4 module using RS-485 Modbus™ RTU protocol. Therefore, the RL-4 module must have a unique Modbus™ address. The module is serially addressed in hex using the two rotary switches on the module’s front panel labeled MSD (most significant digit) and LSD (least significant digit).

The RD-64X remote display has been configured to have two separate relay banks (Bank1 and Bank2). Each bank can support up to two RL-4 modules and are defined by addresses 80h-81h for Bank1 and 82h83h for Bank2. Anytime a specific alarm is fired for a module in a bank, all corresponding alarms for all modules in that particular bank are also triggered. For example, if alarm 3 of a particular module is triggered in Bank2, then all alarm 3’s for all the modules in Bank2 will also be fired. All RL-4 modules must be setup on the COMM1 (master) port of the remote display and their banks assigned to each active channel (See section 7.3.8). The RL-4 modules must be addressed according to Table 1 RL-4 Relay Modbus™ Addresses.

If installing RL-4 modules for the RD-64X, they will need to be mounted in a separate enclosure. For the N4X enclosure, wire the power and Modbus™ from the first RL-4 module to the DIN rail mounted terminal block in the RD-64X-N4X labeled “RS-485 MASTER” and “VDC Out” (See Figure 3). For the N7 enclosure, wire the power and Modbus™ from the RL-4 module to the OUT connector of the transient protection module per Figure 9. If using the AC/DC converter option, wire only the Modbus™ from the first RL-4 module to the J1 connector per Figure 10. The RL-4 modules will need to be powered separately using this configuration. An RL-4 module connected properly to the remote display will have a flashing DATA COMM LED to indicate a valid communication status and will provide a relay output. If an RL4 module is connected, it must be set up accordingly (See section 7.3).

NOTE: RL-4 modules must be connected accordingly to the remote display, they must be addressed correctly and only those RL-4’s associated with a channel will be available.

After identifying the correct address for the RL-4 module, the alarms to be used need to be defined and configured via the operator interface in section 7 System Operation and Configuration. A properly addressed RL-4 that is correctly connected and configured to the remote display will respond to channel activation with an alarm output related to the alarm set points of the associated channel. If the remote display does not detect an RL-4 module, the blue LED (Fault) will start flashing. Go to the FLASHING BLUE LED CODES menu to identify the problem (See section 7.3.10).

Each relay within the bank can be set as Energized/De-Energized, Silenceable/Non-Silenceable, and Latching/Non-Latching (See section 7.3.9).

4.1.1 Energized or De-Energized

All alarms relays - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate in either energized or de-energized mode. In de-energized mode, the normally open contact is open if the alarm level has not been reached (alarm relays) or the sensor is not in fault (fault relay). In energized mode, the normally open contact is closed if the alarm level has not been reached (alarm relays) or the sensor is not in fault (fault relay). Energized mode provides for fail-safe operation since a loss of power or cable failure will cause the contact to be open.

4.1.2 Silenceable or Non-Silenceable

All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate as silenceable, or nonsilenceable. If an alarm or fault is configured as non-silenceable, the corresponding alarm LED and relay, once activated, will stay activated until the cause of the alarm or fault has cleared. If an alarm or fault is configured as silenceable, the corresponding alarm LED and relay, once activated, can be deactivated by acknowledging the Alarm Silence function on the front panel of the X40 controller or by activating the external acknowledge switch if one has been installed (See section 7.1.4 ENTER and RESET/ACK Switch).

relay) condition is cleared. In latching mode, the relay remains active even after the alarm or fault condition has cleared. Once activated, the relay can only be deactivated by acknowledging the Alarm Reset function on the front panel of the X40 controller or by activating the external reset switch if one has been installed (See section 7.1.4 ENTER and RESET/ACK Switch).

4.2 General Wiring Notes

 Follow generally accepted guidelines for RS-485 serial networks. Do not wire devices in long-distance

‘T-Tap’ configurations. Instead, use a “daisy-chain” wiring scheme.

 Use Detcon recommended cabling whenever possible.

• Belden P/N 1502P cable is recommended for a single cable providing serial communications

and power.

• Belden P/N 9841 cable is recommended for a single cable providing serial communications

only.

 Ground the cable shielding at one end only. Other points of grounding may cause a ground loop, and

induce unwanted noise on the RS-485 line, which in turn may disrupt communications.

5. Initial Start-up

The RD-64X remote display will power up as soon as DC power is applied. There is no external power switch to the unit.

NOTE: Before applying power, check to make sure that all the wiring connections and external devices are installed correctly. Applying power with devices hooked up incorrectly may cause damage to the equipment.

When power is applied to the unit, the unit will boot up and display the company name, model, firmware version and COMM ports available. For this unit, that information should be:

DETCON INC COMM1 MODBUS MASTER RD-64X COMM2 MODBUS SLAVE Version #.##X

It will proceed to poll Modbus™ addresses from the attached controller. The display will show up to 8 channels at one time. The LCD will then refresh and display the next 8 channels and so on until the LCD cycles back to the first 8 channels and repeats the process. This is considered normal operation.

If a previous configuration does not exist, the user will need to configure the network from the userinterface. After the unit has been configured, the unit will begin normal operation. If the unit has been configured properly, the unit will display the current status of the devices that it is configured for.

6. Secure Digital Card

The RD-64X remote display has a feature that allows data logging when a secure digital (SD) memory card is installed. The SD card must be installed in the SD slot (J9) on the back of the remote display’s PCA before the remote display is powered up. The remote display will notify the user if a successful installation of the card was achieved upon power up. If successful, the remote display will automatically format the card and create the necessary files for data logging. See section 7.3.17 for more information regarding the data logging feature.

Model RD-64X Operators Manual Rev. 0.1 Page 11 of 30

RD-64X Operators Manual

7. System Operation and Configuration

The setup of the RD-64X remote display is critical for proper operation. Modbus™ addresses must be correct on all the devices connected to the controller before the controller will acknowledge them. The number of channels being monitored from the controller must be entered into the remote display to allow it to communicate with them. These same Modbus™ addresses and number of channels monitored need to be configured and entered on the RD-64X remote display so that the information matches the controller. This also applies to the configuration of alarms and relays from the remote display which need to match the controller. Three basic areas need to be configured:

¾ The number of channels being monitored must be determined before setup begins. ¾ Channel information should be configured to match the controller. ¾ Relay outputs must be configured to match the controller.

7.1 Operator Interface

The operator interface of the RD-64X remote display is accomplished via four internal magnetic switches located above its backlit LCD display. The four switches offer a non-intrusive interface and allow for complete configuration of the unit. These switches are labeled: PROG, “u” (Up Arrow), “v” (Down Arrow) and ENTER. The ENTER switch also doubles as a RESET/ACK switch when on the main page only (Not in Menu Mode). With reference to the Menu Flow Chart (See Figure 14), it is easy to learn how to navigate the menus and make changes.

The magnetic programming tool (See Figure 12) is used to operate the magnetic switches. Switch action is defined as a momentary contact (hold) on a switch marker (⊗). For momentary contact, the programming magnet is briefly held on the switch marker (⊗) and then removed. This action will be referred to as a “swipe” for the remainder of this manual.

Figure 12 Magnetic Programming Tool

7.1.1 PROG Switch

From the Main Display, the PROG switch enters into the Main Menu. Once inside the Main Menu, the PROG switch acts as an “Escape” switch that moves backwards in the menu flow chart.

NOTE: While in Menu Mode there are no updates to gas readings on the remote display and no alarms configured to the remote display will be triggered. Only gas readings on the controller will be updated and alarms configured to the controller can potentially be triggered.

7.1.2 “u” Up Arrow Switch

This switch moves the user up the Main Menu flow chart. It is also used to change selected entries within menu selections in the upward direction.

7.1.3 “v” Down Arrow Switch

This switch moves the user down the Main Menu flow chart. It is also used to change selected entries within menu selections in the downward direction.

Model RD-64X Operators Manual Rev. 0.1 Page 12 of 30

RD-64X Operators Manual

7.1.4 ENTER and RESET/ACK Switch

This switch has a multiple-use purpose. The ENTER function is used to accept selections within all menu screens. The Enter switch is also used to execute the Reset and Acknowledge functions. The Reset function releases all latched relays if they have cleared the alarm/fault condition. The Acknowledge function will disengage any silenceable relays that are in a currently active state. This is typically used to silence alarm annunciators, once the end-user has assessed the alarm condition. The RESET/ACKNOWLEDGE switch is only functional from the Main Display and not while in Menu Mode.

MODEL RD-64X-N4X

Remote Display

Figure 13 Front Panel User Interface

NOTE: The controller automatically times out of Main Menu mode and returns to the Main

Display after 15 seconds of inactivity.

NOTE: The RESET/ACKNOWLEDGE function is applicable from the Main Display only.

7.2 Main Display Functions

The Main Display is a 1¼” x 6” backlit LCD that has 4 lines by 40 characters. In normal operation, the configured channels will be displayed up to 8 channels at one time. The LCD screen then refreshes, displaying the next 8 channels and so on until the LCD cycles back to the first 8 channels and repeats the process. This is considered normal operation and each channel’s information will be shown as:

XX> YYY “Device Tag”

Where XX is the corresponding channel number followed by the gas concentration value YYY. If any channel is in any gas alarm condition, “XX> YYY IN ALARM#” will be displayed for that channel. If any gas channel is in fault, “XX> YYY IN FAULT” will be displayed for that channel. If any channel is not communicating with its appropriate device, then that channel will display “XX> 0 COMM ERR”. If

Model RD-64X Operators Manual Rev. 0.1 Page 13 of 30

RD-64X Operators Manual

any of these conditions (alarm, fault or communication error) occur, the LCD display will cycle through the channel screens at a faster rate than when in normal operation.

Four LED indicators on the front panel show alarm and fault alarm output status. The LED’s represent ALM 1 (yellow), ALM 2 (yellow), ALM 3 (red) and FAULT (blue) and are labeled respectively.

7.3 Menu Functions

RD-64X remote display setup is accomplished through the MAIN MENU. The MAIN MENU consists of 17 menu items:

1) AUTO CONFIGURE SYSTEM

2) SET # OF CHANNELS/RL4S/ALARM STATIONS

3) SET # OF RXT-320S

4) SET RF SILENCE AND RF SLEEP

The PROG switch is used to enter the menu mode of the unit by swiping a programming magnet over the corresponding marker “⊗”. Upon entering the MAIN MENU, the LCD will display:

MAIN MENU

AUTO CONFIGURE SYSTEM

Use the down arrow “v” switch to move to the next menu item or use the up arrow “u” switch to move to the previous menu item by swiping the programming magnet over the corresponding markers. Swiping the PROG switch again will return the unit to normal operation. When the appropriate Menu Item is found, the ENTER switch is used to enter that menu item by swiping the ENTER marker.

NOTE: The RD-64X remote display automatically times out of Main Menu mode and returns to the Main Display after 15 seconds of inactivity. While in Menu Mode, there are no updates to gas readings.

NOTE: The LCD has a backlight that will automatically turn off after a user-defined amount of inactivity. The LCD backlight will turn on automatically as soon as any magnetic switch is activated. This is a feature designed to save on power.

There are 17 Main Menu items and their functional descriptions are discussed in the following sections.

RD-64X Operators Manual

Swipe the ENTER marker to initiate the search. The RD-64X will perform an incremental search for available controllers/remote displays (X40s/RD-64Xs) starting with Modbus™ address 01h. The search will continue until Modbus™ address 7Fh is reached or until it is terminated by swiping the ENTER marker which will save the devices found up to that point and proceed to search for available RL4 modules/alarm stations at Modbus™ addresses 80h, 81h, 82h and 83h or until it is terminated by swiping the ENTER marker which will save the RL4 modules/alarm stations found up to that point and proceed to search for available RXT-320 transceivers starting with Modbus™ address 01h. The search will continue until Modbus™ address 8Fh is reached or until it is terminated by swiping the ENTER marker which will save the RXT-320 transceivers found up to that point. A swipe of the PROG marker at any time while in search mode will cancel the search and restore the default settings. Any devices found up to that point will not be saved.

7.3.2 Set # of Channels/RL4s/Alarm Stations

The SET # OF CHANNELS menu allows the user to set the number of active channels (1-64) to be monitored and to set the number of RL-4 modules/alarm stations (up to 2 each) for Bank1 and Bank2. The number of active channels should match the number of sensors connected to the controller being monitored. Upon entering this menu, the LCD will display:

SET # OF CHANNELS/RL4S/ALARM STATIONS:

CHANNELS: ##

RL4 MODULES/ALARM STATIONS

BANK1: # BANK2: #

These values can be changed by swiping the magnet over the markers of the up or down arrows to move the arrow prompt “→” to the desired location. A swipe over the ENTER marker will select the field indicated by the arrow prompt “→” and the value can be changed by swiping over the markers of the up or down arrows. Another swipe over the ENTER marker will save the selected value.

NOTE: The number of activated channels can be less than (but not greater than) the remote display’s maximum input capacity.

7.3.3 Set # of RXT-320s (Wireless Function Only)

The SET # OF RXT-320S menu is only applicable to RD-64X remote displays that have the wireless option installed. This menu is used to automatically search for all available RXT-320 transceivers in the network. Upon entering this menu, the LCD will display:

SETUP RXT-320S:

RXT 320S IN NETWORK: ##

[CONFIGURE]

Swipe the ENTER marker to initiate the search. The RD-64X remote display will perform an incremental search for available RXT-320’s starting with Modbus™ address 1 (decimal). The search will continue until Modbus™ address 143 is reached or until it is terminated by swiping the ENTER marker which will save the RXT-320’s found up to that point. A swipe of the PROG marker while in search mode will cancel the search and will not save any RXT-320’s found up to that point.

7.3.4 Set RF Silence and RF Sleep (Wireless Function Only)

The SET RF SILENCE AND RF SLEEP menu allows the user to initiate radio silence over the whole network. Radio silence terminates communication between all the RXT-320 transceivers in the network. This menu also allows the user to initiate RF sleep for a set amount of time. This sleep function lets the

Model RD-64X Operators Manual Rev. 0.1 Page 16 of 30

RD-64X Operators Manual

RD-64X remote display broadcast a sleep command to all the RXT-320 transceivers in the network and is used as a power saving feature. Upon entering this menu, the LCD will display:

RF SILENCE AND RF SLEEP:

RF SILENCE: | RF SLEEP:

| ##:##

XXX | SLEEP:XXX

Swipe the magnet over the markers of the up or down arrows to move the arrow prompt “→” to the desired location. A swipe over the ENTER marker for RF SILENCE and SLEEP will toggle the value between ON and OFF. A swipe over the ENTER marker for the RF SLEEP timer will select the field as indicated by the arrow prompt “→” and the value can be changed by swiping over the markers of the up or down arrows. Another swipe over the ENTER marker will save the selected value. The sleep timer has a range from 0 – 5 minutes and is set in minutes and seconds.

RF Silence is used to prevent the radios from possibly interfering with other RF devices on site (such as remote detonators). Once set to ON, it will stay on until the user turns it OFF. In RF silence, the sensors are not monitored and no alarms can be activated. When sleep is enabled, the sensors are each polled once, and then the wireless transceivers are turned off for the sleep period. Once the sleep period expires, the transceivers are turned back on and the sensors are polled once more. This cycle repeats indefinitely. The sensors are not updated and the alarms are not activated while the wireless network is asleep. The longer the sleep time, the longer the possible delay between alarm conditions occurring and the alarms being activated. However, a longer sleep period will increase the battery run time.

7.3.5 Set COMM Baud Rates

The SET COMM BAUD RATES menu displays the current baud rate settings for COMM1 (master) and COMM2 (slave). Upon entering this menu, the LCD will display:

SET COMM BAUD RATES:

COMM1 BAUD RATE:9600 COMM2 BAUD RATE:9600

NOTE: The value shown is pre-configured to 9600 bps (bits per second) and should not be altered unless directed to do so by Detcon Factory Personnel.

7.3.6 Set Modbus Timeouts

The SET MODBUS TIMEOUTS menu allows the user to set the response timeout and the inter-poll delay for Modbus™ communications. Upon entering this menu, the LCD will display:

SET MODBUS TIMEOUTS:

RESPONSE TIMEOUT:### INTERPOLL DELAY:###

Model RD-64X Operators Manual Rev. 0.1 Page 17 of 30

RD-64X Operators Manual

Response timeout is the amount of time in milliseconds the RD-64X remote display will wait for a slave device (controller) to respond to a poll request. Ten missed poll responses will result in the slave device being declared in COMM ERR. Inter-poll delay is the amount of time in milliseconds the RD-64X remote display will wait after sending a poll request to an address and before polling the next address. The range of values for the response timeout is 100-1000 milliseconds and 10-255 milliseconds for the inter-poll delay. The recommended value for the response timeout is 500 and 150 for the inter-poll delay.

7.3.7 Setup Channel Data

The SETUP CHANNEL DATA menu allows configuration of parameters necessary for monitoring each device. The parameters set for each channel should match those of the device that the channel is monitoring. When a sensor or device is being added to the controller, its information will need to be added or modified in this menu. The information to be configured is the SLAVE ID, DEVICE TYPE, REGS TO READ, READING REG, DECIMAL POINT, RANGE and TYPE. Upon entering this menu, the LCD will display:

CHANNEL 1 DATA: READING REG:# SLAVE ID:## DECIMAL POINT:#

DEVICE TYPE:XXX RANGE:##### REGS TO READ:# TYPE:XXXXXXXXX

A flashing cursor will appear on SLAVE ID. Swiping the magnet over the markers of the up or down arrows will move the flashing cursor to the desired location. A swipe over the ENTER marker will select the field indicated by the flashing cursor and the value can be changed by swiping over the markers of the up or down arrows. Another swipe over the ENTER marker will save the selected value and return to the flashing cursor.

The SLAVE ID is the Modbus™ address in hex (01-7F) of the controller the RD-64X remote display is monitoring.

The DEVICE TYPE values available are 140, 240, 440, 840, 12B, 10B, 10C, 880A, 1600A, RD8X, RD32X, RD64X, MCX, X40 and FM. These values represent various control devices and remote displays. Choose the appropriate value for the controller type that is being monitored by the RD-64X.

The REGS TO READ value represents the registers to read and the value is dependent on the DEVICE TYPE selected. This value should not be altered unless directed to do so by Detcon personnel.

The READING REG value represents the reading register and the value is dependent on the DEVICE TYPE selected. This value should not be altered unless directed to do so by Detcon personnel.

The DECIMAL POINT value can be 0, 1 or 2. It corresponds to the number of digits displayed to the right of the decimal point of the gas concentration value displayed. Typically, if the sensor range is less than 10, this value will be ‘2’. If the sensor range is between 10 and 25, then this value will usually be ‘1’. The DECIMAL POINT value should be ‘0’ if the sensor range is greater than 25.

The RANGE value can be selected from 1-10,000 and corresponds to the gas range value of the sensor.

NOTE: If the range is changed, the alarm levels will have to be reset!

The TYPE value is an alphanumeric string of nine characters and corresponds to the tag that is displayed with the gas concentration value. This field is normally used to define the gas concentration units and the gas type. When changing this value, the first alphanumeric character to be modified will be indicated by an underscore and can be changed by swiping the magnet over the markers of the up or down arrows. A swipe

Model RD-64X Operators Manual Rev. 0.1 Page 18 of 30

RD-64X Operators Manual

over the ENTER marker will select the displayed value and the next character to be changed will be indicated by the underscore. Follow these same steps to input all nine characters. The last swipe over the ENTER marker will return to the flashing cursor.

7.3.8 Set Channel RL4/Alarm Station Banks

The SET CHANNEL RL4/ALARM STATION BANKS menu allows assignment of the RD-64X’s banks for each active channel. Upon entering this menu, the LCD will display:

RL4/ALM STATION BANK FOR CHANNELS #-# CHANNEL 01:ALL CHANNEL 04:ALL CHANNEL 02:ALL CHANNEL 05:ALL CHANNEL 03:ALL CHANNEL 06:ALL

where ‘#-#’ represents the range of the channels being displayed and will depend on the number of channels configured. Up to six channels can be displayed at a time.

The selectable values are 1, 2 or ALL and define the remote display’s bank that a channel is related to, whether it’s associated with Bank1, Bank2 or both.

To move to the next set of channels (if available), a swipe of the down arrow marker should be performed while the arrow prompt is on the last channel in the set which will scroll the display to the next set of channels allowing for their configuration. To return to the previous set of channels, a swipe of the up arrow marker should be performed while the arrow prompt is on the first channel in the set.

7.3.9 Set Relay Function

The SET RELAY FUNCTION menu allows for configuration of the RL4 relays connected to the RD-64X. The information to be configured is LATCHING, ENERGIZED and SILENCEABLE for the relays. Upon entering this menu, the LCD will display:

FAULT RELAY SETUP: BANK 1 & 2 LATCHING:X LATCHING:X ENERGIZED:X ENERGIZED:X SILENCEABLE:X SILENCEABLE:X

The first relay to be displayed will be the FAULT relay followed by ALARM1, then ALARM2 and finally ALARM3. A flashing cursor will appear on LATCHING. Swiping the magnet over the markers of the up or down arrows will move the flashing cursor to the desired location. A swipe over the ENTER marker will select the field indicated by the flashing cursor and the value can be changed by swiping over the markers of the up or down arrows. Another swipe over the ENTER marker will save the selected value and return to the flashing cursor. A swipe of the down arrow marker while the flashing cursor is on SILENCEABLE will scroll the display to the next relay allowing for its configuration. To return to the previous relay, a swipe of the up arrow marker should be performed while the flashing cursor is on LATCHING.

There are four relay outputs. Three relay outputs are used for ALM1, ALM2 and ALM3 and the fourth relay output is used for the FAULT condition. All four relays outputs must be set-up to account for the

Model RD-64X Operators Manual Rev. 0.1 Page 19 of 30

RD-64X Operators Manual

following three settings: Latching or Non-Latching, Energized or De-Energized and Silenceable or NonSilenceable. The values selected can be either Y (Yes) or N (No).

Energized or De-Energized

Silenceable or Non-Silenceable

All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured to operate as silenceable, or nonsilenceable. If an alarm or fault is configured as non-silenceable, the corresponding relay, once activated, will stay activated until the cause of the alarm or fault has cleared. If an alarm or fault is configured as silenceable, the corresponding relay, once activated, can be deactivated by acknowledging the Alarm Silence function on the front panel of the RD-64X remote display or by activating the external acknowledge switch if one has been installed.

Latching or Non-Latching Relays

All alarms - Alarm 1, Alarm 2, Alarm 3, and Fault - can be configured as either latching or non-latching. In non-latching mode, the relay is deactivated as soon as the sensor alarm (alarm relays) or fault (fault relay) condition is cleared. In latching mode, the relay remains active even after the alarm or fault condition has cleared. Once activated, the relay can only be deactivated by acknowledging the Alarm Reset function on the front panel of the RD-64X remote display or by activating the external reset switch if one has been installed.

NOTE: It is generally recommended to set the FAULT relay as energized so that it will trip upon loss of power.

NOTE: The FAULT condition is assigned to the FAULT relay as a standard. It cannot be disengaged in the configuration of the controller. The Main Display will show IN FAULT for any channel that is in fault.

7.3.10 Flashing Blue LED Codes

The FLASHING BLUE LED CODES menu allows the user to interpret the fault status of the RD-64X remote display when the blue fault LED is illuminated. Upon entering this menu, the LCD will display any fault codes available. Perform a swipe of the down arrow marker to scroll the display to the next available code. Perform a swipe of the up arrow marker to scroll the display to the previous code. To exit this menu, a swipe over the PROG marker can be performed at anytime. If there are no fault codes, NO ERRORS FOUND will be displayed. There are 7 fault codes available:

1. Channel Comm Errors

2. Channel Faults

3. RL4 Comm Errors

4. RXT-320 Comm Errors

5. RXT-320 Battery Faults (The battery fault can be acknowledged by swiping the magnet over the

RESET/ACK marker)

6. RXT-320 Battery Alarms

7. Inhibit/Test Mode Status

7.3.11 Set Modbus Address

The SET MODBUS ADDRESS menu allows the user to set the serial address of the RD-64X remote display when it is to be polled by another master device via its RS-485 Modbus™ RTU slave port (COMM2). Upon entering this menu, the LCD will display:

MODBUS ADDRESS:

###

This value can be changed by performing a swipe over the ENTER marker and then swiping over the markers of the up or down arrows. Another swipe over the ENTER marker will save the selected value. The range of values for the Modbus™ address is 01-127 in decimal value.

7.3.12 Inhibit & Alarm Test Mode

The INHIBIT & ALARM TEST MODE menu allows the user to inhibit functionality of alarms in the network as well as simulate alarm conditions and verify relay contacts. Upon entering this menu, the LCD will display:

INHIBIT & ALARM TEST MODE

INHIBIT MODE: | ALARM TEST MODE:

#:## |

START | OFF

The INHIBIT MODE has a timer range from 0-60 minutes. Once the timer value has been entered in minutes and seconds, select START and all relay outputs on the network will be disabled until the timer reaches 0 or is manually stopped by the user.

When turned ON, the ALARM TEST MODE simulates alarm conditions by incrementing the gas readings from 0 at 5% full scale for all active gas channels. When full scale is reached, the readings will decrement back to 0 and the unit will exit the test mode. The test mode can also be terminated at any time during the test cycle by turning OFF the alarm test mode. As the readings cross their respective alarm set points, the relays will fire according to their configuration.

7.3.13 RF Link Quality and Battery Status (Wireless Function Only)

The RF LINK QUALITY AND BATTERY STATUS menu displays the network RF link quality between the RXT-320 transceiver of the RD-64X remote display and of the RXT-320 transceivers of the wireless sensors configured to the controller being monitored by the display. This menu also displays the battery life of the Smart Battery Packs powering the RXT-320’s of the wireless sensors. Upon entering this menu, the LCD will display:

F0> ------------------ BATTERY:DC POWER 01> RF LINK:##% BATTERY:##D ##H ##M

The first line corresponds to the information of the RD-64X remote display’s RXT-320 transceiver (indicated by the transceiver’s Modbus™ address ‘F0’) and will only show the BATTERY status since there is no link quality available. The other lines correspond to the RXT-320 transceiver information of the

Model RD-64X Operators Manual Rev. 0.1 Page 21 of 30

RD-64X Operators Manual

slave devices controlled by the controller on the network. Each transceiver available will be identified by its Modbus™ address followed by the RF LINK value and BATTERY status. The RF LINK value is a percentage representing the RF link quality between the remote display’s RXT-320 transceiver and the slave device’s RXT-320 transceiver. The BATTERY status will be either DC POWER or ##D ##H ##M where DC POWER indicates the transceiver is powered by a DC power supply other than a Smart Battery Pack. The ##D ##H ##M value corresponds to the days, hours and minutes of life remaining for the Smart Battery Pack connected to the slave device’s transceiver. The battery life is only displayed in D/H/M when the remaining life is less than 45 days. If it is more than 45 days, it is displayed as a percentage of battery life remaining.

NOTE: While in the RF LINK QUALITY AND BATTERY STATUS menu, the remote display performs a complete Modbus™ poll cycle and automatically times out of the menu and returns to Main Menu mode after 60 seconds of inactivity.

7.3.14 System Diagnostics

The SYSTEM DIAGNOSTICS menu performs function tests for the LCD display, the panel LED’s, the relays and Modbus™ interface. Upon entering this menu, the RD-64X remote display will automatically initiate a function test that displays every pixel of the 4 line, 40 character LCD display. The RD-64X remote display then performs a function test of the LED drivers by illuminating all four LED’s. It will then initiate the relay driver test and reset all the relays. Alarm1 relay will then be turned on. The user will be prompted to “press (swipe) any key (marker)” which will turn on the alarm2 relay. The user will be prompted again to “press any key” and the alarm3 relay will be turned on. The user will be prompted again to “press any key” and the fault relay will be turned on. The user will be prompted again to “press any key” and all relays will be reset once more and the RD-64X will initiate the Modbus™ driver test. The user will then be prompted to connect COMM1 A & B (master) to COMM2 A & B (slave) for a Modbus™ loop back test. The user will be prompted to “press any key” which initiates test 1 of 2 and performs a Modbus™ communication test at 4800 baud rate. The test will perform 127 iterations and indicate the number of errors received if any. The user has the option to abort the test at any time by “pressing any key”. Once the test 1 is complete or has been aborted by the user, test 2 of 2 will initiate automatically and perform 127 iterations of the Modbus™ communication test at 9600 baud rate. Both Modbus™ tests can be terminated at any time by the user. When these tests are completed the display will revert back to the SYSTEM DIAGNOSTICS menu.

NOTE: When performing the Modbus™ loop back test, the loop back cable should be installed between the COMM1 (Master) port and the COMM2 (Slave) port. Disconnect all other external Modbus™ interfaces from the loop and bypass any installed RL-4 modules.

7.3.15 Display Settings

The DISPLAY SETTINGS menu allows the user to customize the brightness, contrast and backlight duration of the display. Upon entering this menu, the LCD will display:

Once the desired values have been set, move the arrow prompt to “Change Date” and swipe the ENTER marker to update the date with the changes entered. A swipe of the PROG marker at any time while setting the time or date will escape out of the current menu with no changes saved.

7.3.17 View TWA & Peak

The VIEW TWA & PEAK menu allows the user to view the recorded time weighted average (TWA) and peak readings for each channel represented by its assigned gas sensor. To use this menu function, a secure digital (SD) memory card must be installed in the SD slot of the RD-64X remote display board (J9). The data is recorded on the SD card with the date, time, channel number, TWA and peak readings every time the controller polls a sensor. Upon entering this menu, the user can view the data recorded from the SD card and is displayed as:

<File Name>:

MM/DD/YY, HH:MM:SS, Channel #, TWA #, PEAK #

Example: TWA_P08.CSV: 05/17/11,23:00:09,17, 51, 100

The sensor readings are continuously logged to the SD card. This data can also be viewed by removing the SD card and inserting it in a laptop that has the Detcon Log File Viewer application installed. Refer to the Detcon Log File Viewer instruction manual for more information.

9. Wireless Option (RXT-320)

The Model RD-64X remote display offers a wireless option that is designed to take Modbus™ communication between devices to a wireless platform. This option takes local Modbus™ communication, and through the use of a wireless network of transceivers, broadcasts this information throughout a wireless network platform, creating a seamless network of Modbus™ devices that need not be physically connected in any way.

The wireless function of the RD-64X remote display is made possible by Detcon’s RXT-320 wireless transceiver. This transceiver transmits signal data such as analog 4-20mA DC or serial Modbus™ and can support up to 32 devices. It operates at 2.4GHz and conforms to non-licensed radio frequency appliance usage around the world. Wireless network integrity and security is accomplished using direct sequence

Model RD-64X Operators Manual Rev. 0.1 Page 26 of 30

RD-64X Operators Manual

spread spectrum wireless mesh technology. Wireless applications can be as simple as a single field device communicating with a host controller or any number of field devices forming a network of subscribers. Each device in the network is assigned a Network ID and a Modbus™ address. Processing power is based in a designated Modbus™ master while every slave device in the network is capable of functioning as a router and repeater for all other devices in the network. This means that subscribers can “hop” through neighboring devices to communicate with each other thereby widening network access points. This unique and innovative technology is designed to create a robust network that automatically routes around congestion and line-of-sight obstacles while improving throughput as subscriber device density increases. Refer to the RXT-320’s instruction manual for more detailed information.

The connection between the RD-64X and the controller can be made using a pair of RXT-320 transceivers. This is accomplished by connecting an RXT-320 to the Modbus slave port on the controller and a second RXT-320 to the Modbus master port on the RD-64X. The connection between the RXT-320 and the RD64X is made through a Transient Protection Module. This connection is shown in the lower half of Figure

16.

A secondary RD-64X can be connected to the primary RD-64X using a second pair of RXT-320 transceivers. This is accomplished by connecting an RXT-320 to the Modbus slave port on the primary RX64X and a second RXT-320 to the Modbus master port on the secondary RD-64X. The connection between the RXT-320 and the primary RD-64X is made through a Transient Protection Module. This connection is shown in the upper half of Figure 16.

NOTE: When both the master and slave ports of the RD-64X use RXT-320 transceivers, the master port RXT-320 must be on a different RF channel than the slave port RXT-320. Refer to the RXT Instruction Manual for more information on setting the RF channel.
