Troubleshooting with Control System
The control system offers the following troubleshooting aids, described in the
manual Control System:
S Indication lamps and light tower
S Diagnosis program in the temperature section
S Automatic fault display in the temperature section
S Service display Error in the motor section
S LEDs on the modules and boards.
Indication Lamps and Light Tower
With the exception of the yellow light on the light tower, the indication lamps
and the light tower indicate the same modes as the control system:
S Red = Collective fault. The red lamp indicates that the control system has
recognized a fault.
S White = Switched ON. After switching on and during the heatup phase, at
first only the white indication lamp is lit (normal condition). A fault has only
occurred when the temperature does not increase (observe temperature
display) and when the green indication lamp is not lit after the heatup
phase has ended (1 hour and longer).
S Green = Ready for operation. The green indication lamp lights when all
channels have reached their setpoint temperatures.
S Yellow = Lower tank level, as set by customer.
