7 Troubleshooting

7.1 Diagnostics

Trouble Reason

Solution

Power not applied

Measure power on terminal block X1
terminal H / N for 120 VAC (24

Fuse failure

Check miniature fuses 1F1, 1F2 or F1 on
motherboard

Interruption in the cable
connection between motherboard
and displayboard

Check cable connections for tight fit

No indication of power
(opional with display),

and/or

test button does not
function

Failure on displayboard

Replace displayboard

Mode operating switch S1 on
displayboard, position 3 = OFF

Set switch in position:
1 = low trip/setpoint
2 = high trip/setpoint
4 = sensed value

Interruption in the cable
connection between motherboard
and displayboard

Check cable connections for tight fit

No indication value at
digital display

Failure on displayboard

Replace displayboard

Interruption in the cable
connection between motherboard
and displayboard

Check cable connections for tight fit

Sensor sensitivity too low

Replace sensor

Cannot calibrate
sensorboard

Failure on sensorboard

Replace sensorboard

Trip/setpoint values are set too
high

Adjust trip/setpoint values again
(see section 5.1 to 5.3)

Cannot set trip/setpoints

Failure on motherboard

Replace motherboard

Interruption of sensor cable or
sensor sensitivity too low

Check cable connection, or if necessary
replace and calibrate sensor

Fail-safe alarm

Control span voltage lower then
200mV

Recalibrate the sensor, or if necessary
replace sensor element
