AI gas concentration
Output value of the
separation stage is incorrect
Connection to the
separation stage is
interrupted, separation
stage defective, incorrectly
configured
Check the connection
to the separation
stage, check the output
signal of the separation
stage
591
AI coding resistor
Measured resistance is
incorrect
Resistor is loose or
defective or resistance
value is incorrect
Test the electrical
resistance
592
Coding changed
Coding error
The resistor has measured
different coding (number
of compressors) since the
last switching on
Coding resistor
defective, not
connected, check the
contact

DI emergency stop
Emergency shutdown has
tripped
External contact
Check the external
conditions
602
DI 3-phases
Phase monitoring has
tripped
Error in relation to phase
sequence, phase failure,
undervoltage and
asymmetry
Check feed

DI mpcb Pump 1
DI mpcb Pump 2
DI mpcb pump freec.
Motor protection switch has
tripped
Motor current above the
allowable range,
Motor is running in two
phases only, rotational
direction,
poor contact at terminal
connections,
interturn short-circuit,
earth fault, rotor blocked.
Check the motor power
consumption, check
the operating point,
check the electrical
connection of the
components

DI pump 1 error
DI Pump 2 error
Internal monitoring of the
pump tripped
Motor is running in two
phases only, rotational
direction,
poor contact at terminal
connections,
interturn short-circuit,
earth fault, rotor blocked.
Check the motor power
consumption, check
the electrical
connection of the
components, check for
mechanical blocking,

Pump 1 flow start
Pump 2 flow start
Flow switch did not switch
through after the pump
start-up phase
Flow too low
Check flow, check shut-
off valves, check pump,
check the setting of the
reed contact at the
flow monitor
