It could happen that the values of a current input present an anormal drift from other signals
Usually, it happens after a cabling mistake damaging a resistance inside the input module.
Product affected :
- Module CIM 4/20 :
- Product number : 9183-20C21-100
9183-20C21-101
9183-20C21-102
- Module AGM 4/20 :
- Product number : 9183-20C2D-102
Note : for the product number finishing with 103 and up, the impedance is 200 ohms and are not affected by this issue.
To validate if the drift is caused by a defective input module :
- Power off the ZPU
- Remove the connection of the sensor
- Measure the resistance between Signal + and Signal -. Normal value must be 100 Ω +/- 1 Ω
Note, it's possible to fix a defective module, contact us to initiate a RMA process to send back the module at the VibroSystM factory for repair.
