Maybe is 24V dc supply interrupted
to the display. There shall be 24V
dc at this connector.
Remove jumper in pin 11 and pin
12. In order to ensure that there
can be measured mA must pin 11
and pin 12 must be screwed.
Remember to set the measuring
instrument in dc mA and connect
test leads correctly in the
measuring instrument. Sensor is
alright when measuring a value
between 4 and 20 mA. Is the result
about 2 mA then there is an
internal sensor error, so the sensor
must be sent for repair. Is the
result 0 mA, tjek if the sensor get
24 Vdc power.
