 Make sure JP1 is in place for DC
voltage
 If the Power checks out, call Arjay
Service.
2. 4-20mA output does not track the gas
concentration.
 Make sure that the EC-Gold Dual
output mode is set to Analog mode
and not to Discrete Voltage Output
mode. See Controller Settings Sheet
section for details.
 Make sure the maximum range of the
remote XMTR is the same as the 2

CO
 Calibration may be required. See the
calibration section for details.
 Call Arjay/Enmet Service for Help if
none of the above fixes the problem.
3. In Discrete Voltage Output mode, the
ISA-66RLU or Gas Alert connected to
the EC-Gold always shows Sensor Fault
 Make sure that the EC-Gold DUAL
