HGM 300 Communications Adapters

 

HGM-LON
The Bacharach HGM300-to-Lonworks Communications Adapter Model HGM-LON enables a Model HGM300 refrigerant monitor to communicate with a Lonworks FT-10 free Topology network. Zone ppm readings, flow status, refrigerant selections, and Model HGM300 internal status may be viewed over Lonworks. Each Model HGM300 zone supports three levels of alarming (leak, spill, evacuate), and each alarm threshold can be set over Lonworks. The Lonworks communications adapter can be used in conjunction with the Model RDM800 remote display, if desired.

The adapter is powered from the 120V auxiliary power connection on the Model HGM300 power supply board. The communications adapter board will be installed in the Model HGM300 at the factory. The adapter board mounts on the rear of the Model HGM300 door.

The only Model HGM300 parameters that are changeable through Lonworks are the alarm thresholds. The unit enables remote alarm acknowledgement. Configuring the Model HGM300 for refrigerant type and length of tubing for each zone (zero length to disable a zone) must be done with the Model RDM800 remote display or a laptop PC.

HGM-N2
The Bacharach HGM300-to-Johnson Metasys N2 Communications Adapter Model HGM-N2 enables a Model HGM300 refrigerant monitor to communicate with a Metasys building management system. Zone ppm readings, flow status, refrigerant selections, and Model HGM300 internal status may be viewed on Metasys operator stations. In addition, each Model HGM300 zone supports three levels of alarming (leak, spill, evacuate) through Metasys. The N2 communications adapter can be used in conjunction with the Model RDM800 remote display, if desired.

The adapter is powered from the 120V auxiliary power connection on the Model HGM300 power supply board. The communications adapter board is installed in the Model HGM300 at the factory. The adapter board mounts on the rear of the Model HGM300 door.

The "BAS BUS" (N2) RS-485 communications port on the adapter is electrically isolated from the Model HGM300 and from earth ground. This prevents problems with potential differences in "round" between physically separate locations.

The only Model HGM300 parameters that are changeable through Metasys are the alarm thresholds. The unit enables remote alarm acknowledgement. Configuring the Model HGM300 for refrigerant type and length of tubing for each zone (zero length to disable a zone) must be done with the Model RDM800 remote display or a laptop.
