GASMAX II Operation & Maintenance Manual, Revision 7.0

REMOTE DIRECT TOXIC SENSOR WIRING (CH1)
GASMAX II monitors with remote-mount toxic sensors are shipped in two pieces and sensor wiring must
be installed by the end user. Remote toxic sensors connect to the Channel 1 Simple Sensor input on the
back of the Display Assembly
as shown in Figure 4-6.
Due to the small signal output from toxic sensors, remote direct input toxic sensors should be mounted
no more than 15 wire-feet
from the GASMAX II display. Further, the cable used should be
three-wire
stranded with foil shield
and should be
run inside metallic rigid conduit
. GDS Corp recommends Belden
B8771. The cable shield must be connected to an earth ground at ONE END ONLY.
NOTE: Poured seals and rigid conduit are required if the remote sensor is installed in a hazardous area.
IMPORTANT
: TOXIC SENSORS MAY FAIL TO OPERATE PROPERLY IF POWER IS NOT APPLIED WITHIN 6
MONTHS OF SHIPMENT. CONTACT GDS CORP FOR RECOMMENDATIONS IF THIS SITUATION MAY OCCUR.
