System Malfunctions
Malfunctions occur if CAN bus components have been mounted, wired or configured incorrectly or
if electronic component parts are defective, or in the event of excessive heat in the equipment or
electrical interference in the supply system.
There are four types of malfunctions that might occur in the controller and the measuring sensor.
n Max. admissible temperature in electrode terminal box exceeded
n No or faulty communication between controller and measuring sensor
n Malfunction in CAN bus
n Failure of 24 V power supply unit built in controller or external PSU.
