CAUTION
The 4-20mA analogue output signal will remain INHIBITED at 2mA (default setting) while the
XCD RFD remains in Conguration Mode. However, the ALARM and FAULT RELAYS remain
Active.
Changing the conguration of the Sensor Type or the Gas Star Rating for catalytic sensors
may result in temporary activation of the ALARM or FAULT RELAYS.
Should this occur, recalibrating the sensor will return the XCD RFD to normal condition and
reset the relays.
As a precaution, please take necessary action to manually inhibit any external actuator
or alarm devices that are connected to the XCD RFD Alarm/Fault Relays to prevent
unnecessary activation during commissioning or reconguration of the XCD RFD gas
detector.
For CSA Certied applications, use CB-6 calibrated only to Methane.
