Introduction

Features

• The Universal Display Module is a single or dual channel remote display module designed to achieve remote sensor separation for up to two gas detectors. It is designed to be universal across multiple brands of gas detection allowing the user to interact with the same interface but utilize the best technology for the application within those compatible brands. The UDM is provided in an epoxy painted explosion-proof enclosure with a viewing window.
• The UDM display allows the 4-20mA output signal to pass directly through from the attached gas detector on each channel and does not interrupt or re-create the 4-20mA signal.
• The UDM acts as a digital communication master to each attached gas detector and displays the concentration, plus is as an interface to access the gas detectors menu structure for calibration and various parameter configurations. Additional parameters may be found by accessing each detector directly depending on the make and model of the gas detector connected.

Compatible Gas Detectors
Below is a list of compatible gas detectors at the time of this manual release.

• Detcon 700 series including FP700, DM700 (except DM-700-O2), IR700, TP700
• Sensor Electronics Millenium Series
• Sensor Electronics SEC3000 Series

Safety Guidelines for Safe Use
If equipment is used in a manner not specified in the manual, the protection provided by the equipment may be impaired. It is mandatory to read and follow all the Safety Warnings and Cautions listed below and throughout the manual.

Warning

• When installed in a Class 1, Div 1 / Class 1, Zone 1 area, seals are required as per the certification label.
• When installed in a Class 1, Div 2 / Class 1, Zone 2 area, seals are NOT required as per the certification label.

Warning

• Explosion Hazard.
  Do not open the enclosure or make any disconnections while the circuit is live or unless the area is known to be free of ignitable concentrations.

Installation

Mounting
The UDM can be installed as a wall mount using the mounting tabs of the explosion-proof junction box. Once mounting of the housing is complete, the UDM PCBA can be oriented on the square pattern stand-off’s to ensure the OLED display is horizontal for viewing.
Figure 1: Mounting details

The UDM electronics package consists of one printed circuit assembly (PCA) and a top graphics plate with two captive thumb screws to allow for removal of the PCA assembly from the housing. To install the electronics package, ensure power is off, properly align the 4 holes in the PCA with the four stand-off’s in the housing, slide the electronics assembly down the standoff’s until the faceplate rests on the stand-off’s. Next, tighten the two captive screws onto the standoff’s, (hand tight only) and install the enclosure cover.

Field Wiring

• The field wiring connections are made to the bottom of the UDM PCA using removable terminal blocks. There are three 6-pin terminal block on the bottom of the PCA, Sensor #1, Sensor #2 (if applicable), and Power / Output connections as shown in Figure 2.
• If remote sensor separation is required, the UDM can be separated from the gas detector. Remote separation distances of up to 1000 feet are possible with the recommended cables.
• The recommended cable for remote sensor separation is Belden 8770 (18AWG shielded 3-wire cable) for connection of power and mA signal return and Belden 9841 (24AWG shielded twisted pair) for serial Modbus™ or digital communications.
• NOTE: It is highly recommended to install the interconnecting cabling inside rigid metal conduit to eliminate potential EMI and RFI interference.

Figure 2: UDM Wiring Diagram

Startup / Configuration

Startup
On power-up of the UDM, it will search for connected detectors. If it finds a detector connected it will upload the detector and parameters to the UDM and display the model connected along with the concentration and gas type (i.e. LEL, H2S, SO2). If no sensor is found during the search, the UDM will stop searching and display COMM FAULT on the display for that channel.

Important Notes

• To initiate a new search, a power recycle must be performed.
• Detcon 700 Series Gas Sensor’s must be set to Serial ID = 01 for proper communications with the UDM.
• The UDM does not interrupt or re-create the 4-20mA signal from the attached detector. Therefore, if there is a UDM failure, the attached detector will still send the 4-20mA signal back to the higher-level system and be operational. i.e. The 4-20mA signal output will not be affected and will be operating properly at the PLC but you will lose the ability to remotely access the detector via the UDM’s magnetic interface.
• If one channel on a dual channel UDM is in COMM FAULT, it has no effect on the other channel.

Operator Interface
The operator interface of the UDM is very similar to the Detcon Model 700 series detectors. It uses two magnetic programming switches per channel (PGM1/ZERO and PGM2/SPAN) and utilizes the same programming magnet. When activating the magnetic switches on the UDM, you are interfacing to the attached detector via various serial communication protocols depending on the make and model of the detector. The UDM interface is designed to mimic the Model 700 series Detcon detector interface even when other brands are connected to give the user consistency when operating the menu structure. However, only the functions deemed critical for normal remote sensor operation are available via the UDM. Other menu functions may be available via the detector itself depending on the make and model connected to the UDM.

Magnetic Programming Tool
The magnetic programming tool is used to operate the magnetic switches. To activate the magnetic switch, move the magnet over the circle near each PGM marking on the faceplate. You will see the arrow on the display indicating that the switch is activated.

Operational Menus

The menu structures are as follows:

• Normal Operation
  Current Reading and Fault Status

• Calibration Mode

  • AutoZero
  • Autospan

• Program Mode

  • View Sensor Status
  • Set Autospan Level (If applicable)
  • Display ON/OFF

Normal Operation

• In normal operation, the UDM display continuously shows the current sensor concentration and measurement unit for each channel (i.e. 0% LEL, or 0ppm H2S). With gas concentrations below 10% of the sensors range the status LED will be green for its respective channel.
• At 10% of the detectors range the status LED will flash red to indicate that gas is present.
• In normal operation, each 4-20mA current output displays the gas concentration and full-scale range of the corresponding channel.

Operation During a Fault Condition

• If a channel is actively experiencing any diagnostic faults, a fault message will be present on the display until the channel fault is resolved. When a fault is detected, the status LED will turn amber and flash.
• During a fault condition, the 4-20mA current output signal will be a low mA reading (dependant on the Make and Model of detector attached). See the appropriate detector manual for more details.

View Sensor Status Menu
The “View Sensor Status” menu displays some of the parameters from the connected detectors and will vary depending on the Make and Model of the detector attached.

Troubleshooting Guide

COMM Fault

• Is the channel being used? If no detector is connected to that channel, turn off the display for that channel only to avoid getting the COMM FAULT message.
•  If one channel on a dual channel UDM is in COMM FAULT, it has no effect on the other channel.
• Check that the terminal block is correctly connected and the wiring to the UDM module is correct for the compatible detector.
• For Detcon Model 700 Series Gas Sensors, ensure that the Serial ID is set to address “01” for proper communications with the UDM. The address for the Model 700 is set by accessing the Model 700 menu.
• Check wiring connections if all connections are good recycle power to restart detector searching.
