6.0 Troubleshooting

6.1 Troubleshooting Chart

This section is intended to be a guide to correcting problems, which may arise in the field.
General Monitors should be contacted for assistance if the corrective action listed does not
eliminate the problem. Defective units should be returned to General Monitors for repair with a
complete written description of the problem.

NOTE:

If the equipment is under warranty, any repairs performed by persons other than
General Monitors’ authorized personnel may void the warranty. Please read the
warranty statement carefully.

CAUTION

: Be sure to inhibit or disconnect external alarm wiring before making any check that

might send the unit into alarm.

Table 36: Troubleshooting Chart

PROBLEM

POSSIBLE CAUSE

CORRECTIVE ACTION

Analog output signal = 0 mA
and green LED in window is
off

No DC power to the Unit

Be sure that the +24 VDC is applied
with the correct polarity

Analog output signal = 0 mA
(3.5 or 1.25 mA with HART)
and green LED in window is
rapidly blinking

Low voltage FAULT (voltage at
unit is approxi18.5 VDC)

Be sure that the unit is powered with
at least +24 VDC under load

Analog output signal = 0 mA
(3.5 or 1.25 mA with HART)
and green LED in window is
rapidly blinking, +24 VDC
verified

Flash Checksum Not OK

Re-cycle power to the unit

Analog output signal = 0 mA
(3.5 or 1.25 mA with HART)
and green LED in window is
rapidly blinking, +24 VDC
verified OK, power was re-
cycled

Flash Checksum Still Not OK

Call GM customer support

Analog output signal = 2 mA
(3.5 mA with HART and small
current disabled) and green
LED in window is slowly
blinking

COPM FAULT, dirty or obscured
optical path (detector window)

Clean the window and reflector

Dipswitch settings do not
match those observed in the
operation of the detector

Device settings may have
been changed by either HART or
Modbus and no longer
correspond to those on the
dipswitch

Recycle power to the unit while
connecting the test IO terminal to
ground (refer to Section 3.9 ). After
startup, adjust settings via dipswitch
as described in Sec. 3.7 (Switch
Selectable Options)
