ERROR DESCRIPTION WHAT TO DO
1. No Output and all lights off
• Check the power to the unit. The voltage
should be 24VDC at the power connector
with the positive and negative connected
as shown on the connector label.
• If the Power checks out, call Arjay
Service.
2. 4-20mA output does not track the gas
concentration.
• Make sure that DIP switch 7 is set to Off
(down) position.
• Make sure that the EC-Gold output mode
is set to Analog mode and not to Discrete
Voltage Output mode. See SETTING
CONFIGURATION section for details.
• Calibration may be required. See the
calibration section for details.
• Call Arjay/Enmet Service for Help if none
of the above fix 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 DIP switch 7 is set to the
On (up) position.
• Make sure that the EC-Gold output mode
is set to Discrete Voltage Output mode
and not to Analog.
4. When pressing the Calibration pushbutton
there is no calibration acknowledge (i.e. the
Status LED does not glow orange)
• Make sure the calibration pushbutton is
pressed for at least 2 seconds.
• Make sure that the DIP switches 1-6 are
not all On (Up). This will cause the
Setup mode to be entered when the
pushbutton is pressed. If the Status LED
is flashing green, first press the
calibration pushbutton to exit the Setup
mode, then set switch 6 to the Off (down)
position. Then proceed with the
calibration procedure.
