Electronics Issues (Cont’d)
Analyzer not
communicating
with PC
Multiple reasons could be
causing the analyzer to not
communicate properly with the
PC.
Check that the analyzer is ON.
Check that the communication cable is
properly connected.
If the software application was open before
connecting the communication cable from
the analyzer to the computer, close the
software and re-open it. Try again and
enable communication.
Analyzer not
turning ON
Blown fuse Check fuse in the controller board. Replace
if required.
Controller board Malfunction Consult Envent Engineering Ltd for a
controller board replacement.
Not using the appropriate
voltage rating
Make sure to use the appropriate voltage to
power the analyzer. DC controller boards
can be powered with 12 - 24 VDC and AC
controller boards can be powered with 110
to 240 VAC. Keep in mind that if solenoids
are controlled by the controller board, the
voltage must match the solenoids voltage
rating.
Red LED on
Sensor Block
Sensor block fault Re-zero sensor block. Refer to "Re-zero
Sensor procedure" on page 29.
Check for green status led on sensor block
once procedure is done. If sensor LED
stays red, consult Envent Engineering Ltd
for a replacement.
Wiring not done properly Make sure the wiring is done correctly.
Analog Outputs
(4-20 mA) not
working
Not using an external power
supply
The analog outputs in the controller board
are loop powered and not self-powered
unless AO boards were installed as per
customer request. If AO boards were not
requested, an external power supply must
be used. Refer to "Analog Outputs" on page
16 to see different wiring options.
