Product improvements and enhancements are continuous; therefore the specifications and information contained in this document may change without notice.

Please read this manual carefully before use. Badharach the source voltage matches the voltage of the product before energizing the equipment. DO NOT use soap and water. This enables the HGM to be setup from a personal computer.

Please refer to the Appendix for a more complete discussion of communication protocols.

The HGM should be centrally located in the mechanical room gacharach be readily accessible for easy visual monitoring and servicing. Air sample tubing may be run in lengths up to feet. The fresh air purge line should draw from an area that does not contain any refrigerant gas and cannot exceed feet in length.

The exhaust line should run to an out bacharqch location if possible. Dirt, grease, and oils can adversely affect the operation of the HGM The monitor should be installed out of direct sunlight in a clean, dry area that is not subject to temperature or humidity extremes.

Installation of the monitor in jgm300 mechanical room is acceptable provided reasonable environmental conditions exist. The enclosure utilizes keyhole mounting brackets designed for 12 pan head fasteners. Additionally, a purge line is installed to provide clean air bacharxch resetting the infrared zero baseline. An exhaust line is installed to vent residual gas away from the monitor. The standard configuration of the unit includes one manifold of 4 intake connectors and 1 purge connector.

Locate service knockouts on exterior of enclosure and install electrical conduit in the typical manner. Do one of the following to connect the AC power leads and ground: This is the correct setting if the HGM is connected as a single device, or it is the last device on the network chain.

There are two versions of PC software. The saved program will be sent to the HGM After the software gets the program, open the desired screen.

Use any of the remaining service knockouts to bacharac access to the interior of the monitor. Locate the Dual 4—20 mAdc Output connector Page 7 and remove it from the circuit board.

The relays are factory assigned to the following conditions: The display module should be installed out of direct sunlight in a clean area that is not subject to temperature or humidity extremes.

RDM Mounting Specs Installation Hold the display module flat against the mounting surface and allow it to slide down engaging the screw Use any of the remaining service knockouts to gain access to the interior of the RDM This is the correct setting if the RDM is connected to only one HGM, or if it is the last device on a network chain.

These alarms are useful for alerting the user to global conditions anywhere on the network. Each relay can be programmed to respond to alarm, fault, or ready conditions refer to Setting Relay Parameters on Page The prominent features of the display module are discussed below.

RDM – Screen Displays When first powered up a splash screen appears indicating the serial number and firmware revision number. After a brief moment the System Screen is displayed. Please refer to the Appendix for a logic diagram of all the screen displays. Parameters must also be defined for each HGM monitor connected to the network.

Press the adjacent bacgarach to adjust the setting. These values must match the dip switch settings on each HGM circuit board. Location This is the name you assign to the HGM to identify its bacharahc. It may have up to 12 alphanumeric characters.

To calculate ghm300 current output, multiply the scale factor by the PPM and add 4. For example, at the default scale factor of 0. Distance This is the tubing length in feet from the HGM to the termination of the air intake line. This value may range from bachwrach to feet.

The default value is feet. Average Temperature This temperature reading bwcharach be changed to the exact temperature at the sample point for greater accuracy. Press the adjacent key to adjust the value. This value must be less than the evacuate level and greater than the leak level. The RDM operates by polling the bachqrach approximately once every 12 seconds to determine the current status of the HGM monitors.

If more than one HGM is connected to the network, it will sequentially poll each monitor for its status. As a practical matter this simply means that the more complicated the network, the longer it will take the RDM to update the status information for all zones. Zone Hold Mode A zone can be placed on hold and continuously monitored for a length of time determined by the Zone Hold Time value Page To place a zone on hold, press and hold down the key adjacent to that zone until you hear a beep.

The boxes on the left side of the screen indicate the status of each HGM monitor including the name, the current zone, and whether fault or alarm conditions are present on the network.

Once the HGM completes a measurement cycle in the affected zone the alarm condition will be bacharaach. Alarm Detail Screen The Alarm Detail Screen displays more comprehensive information about the nature of the alarm including: Repeat this procedure to acknowledge any remaining alarms. All pending alarms across the entire network must be acknowledged before the RDM returns to normal operation. The log interval is the number of minutes from 1 to between each log point.

This parameter can be changed from Zone Setup Screen 1 Page Check for a blockage in jgm300 air sample line or at the line end filter.

Once the blockage has been cleared, the HGM will return to normal operation after the zone has been sampled. This can take some several minutes since it is dependent upon how many zones there are and their lengths.

Clearing System Faults If the fault condition is associated with an HGM, the bachaach will return to normal operation soon after the problem is corrected. Connect the sample bag directly to the intake port for the bacharqch you have set up and allow the HGM to sample the entire bag. When sampling is complete, view the trend data for the zone used to sample Page Programming New Gasses As new refrigerants come into use the HGM allows the addition of these new gases to its on-board refrigerant gas library.

At the end of the gas library list are five place-holders for adding new gases. PPM — Parts Per Million is the volume concentration referenced to standard temperature and pressure and is computed from lines 5, 8 and There are two figures given. The second is a PPM reading normalized to standard temperature and pressure. The default is 60 minutes. This time interval can be changed as described under the heading Service Timeout on Page The interface board plugs into the socket provided on the main circuit board, and the external devices are then cabled to the HGM as described earlier in this manual.

If you are unfamiliar with complex systems of this type, it is recommended that you contact Bacharach for technical assistance. This document will assume that the reader is familiar with the various parameters used to setup the HGM, as well as the different operational modes that the HGM may be placed in.

If you are unfamiliar with this information, please reference the HGM bachaach manual. The zone number is the low order byte in the register address i. It is strongly recommended that any New Gas curves that are added be done in conjunction with help from Bacharach, Inc. In order to place the HGM into hold mode use the following sequence: Hgm30 Log Register Register 0x, 0xh bytes These registers contain the 20 most recent fault events, the time they occurred, and a pointer to the most recent event.

The data is split into 2 registers. The first register contains bytes and the second register contains bytes. In order to place the HGM into service mode use the following sequence: Service Pursuant to the stated warranty, Bacharach, Inc.

Labor beyond ninety 90 days of shipment or installation is subject to charge. It offers a wide variety of displays and can fully program any associated monitor.
