Warnings
refill the coolant up to the MAX-mark (tank)
causes: leakage, evaporation, defective level switch
clean or change air filter
causes: defective (differential) pressure switch
insert air filter
causes: defective monitoring switch
check coolant circuit
causes: defective pump/valves/hoses, defective flow sensor, soiled filter (if present)
Misc. warning 1 (definition: see circuit diagram input
E03)
depending on the function
Misc. warning 2 (definition: see circuit diagram input
E04)
depending on the function

change DI cartridge
causes: no use of DI water, defective valve for conductance control
Automatic venting process
(Time delayed, automatic restart of the plant)
* signaling via alarm interlock
Valve setting not in air vent position
No action required: automatic restart after max. 300 seconds
Low temperature warning
* signalling via alarm interlock / MFO-Interlock
temperature is less than parameter A28
High temperature warning
* signalling via alarm interlock / MFO-Interlock
temperature is greater than parameter A29
Refrigeration Circuit | low pressure warning
*signalling via alarm interlock / MFO-Interlock
contact service hotline
causes: loss of refrigerant, defective refrigerant component
Refrigeration Circuit | high pressure warning
* signalling via alarm interlock / MFO-Interlock
Air cooled: Clean air filter and check air supply
Water cooled: Clean strainer
Contact service hotline if necessary
causes: defective fan, no flow in external water circuit, open housing
Refrigeration Circuit | Motor circuit breaker has
triggered
* signalling via alarm interlock / MFO-Interlock
open switch cabinet and reset motor circuit breaker
cause: defective live component
Defective conductance sensor
measured value out of range
check electrical connection
change conductance sensor
