Settable on screen Cae30 Automatic / manual (settable on screen
Cae30)
- Check correct compressor operation (presence of liquid, size, refrigerant charge,...)
- Check evaporator valve operation and status (blocked valves, incorrect confi guration,
wiring, etc.).
- Check MPXPRO / UC setting (probe operation and positioning, correct parameter
confi guration, comparison of probe reading with pressure gauge reading)
Settable on screen Cae41 Automatic / manual (default)
- Check correct reading of probes set for SH (probe p_suct and T_suct)
-Check compressor status (presence of frost on the outside)
-Check liquid return from evaporators (SH reading from MPXPRO and UC)
Not present Automatic
- Check inverter power supply
- Check phase connection between compressor and inverter (wiring and connections)
- STO
- Check inverter parameters confi guration (baud rate, parity, number of bits)
Dependent on polling
time of Fieldbus con-
nection
Automatic
- Check inverter operation and status
- Check inverter manual alarm list (explanation of alarms that may be present in the
inverter)
Not present Automatic
Check compressor connections to the inverter (reversed phases, incorrect wiring and
connections,...)
- Check correct operation of the compressor (liquid in the compressor, excessive charge
in the circuit,...)
- - Check evaporator valve status (valves blocked open)
- Check P_disch positioning, installation and correct operation (check positioning before
valve at compressor discharge, check correct reading of values )
- Check P_suct positioning, installation and correct operation
Settable on screen Cag51 After a certain number of attempts, the
alarm is no longer automatically reset.
Settable on screen Cag51
SERIOUS AND
BLOCKING
AFTER 5
ATTEMPTS
- Check P_disch positioning, installation and correct operation (check positioning before
valve at compressor discharge, check correct reading of values )
- Check P_suct positioning, installation and correct operation
- 8 working zones out of envelope
- Check correct compressor operation (amount of charge, size, presence of liquid,..)
Settable on screen Cag55 Automatic
- Check temperature probe installation and correct operation (wiring, electrical connec-
tions and comparison with a pressure gauge reading)
- Check compressor (liquid injection function enable if discharge temperature is too
high, connections with inverter)
- Check amount of charge inside the circuit (limited charge)
Not present Automatic
- Check correct compressor correct operation (amount of charge, size, presence of
liquid,...)
- Check P_disch positioning, installation and correct operation (check positioning before
valve at compressor discharge, check correct reading of values)
- Check P_suct positioning, installation and correct operation
- Metallic compressor noise due to lack of oil lubrication
Settable on screen Cag55 Automatic
- Check installed inverter model matching with the model required by the compressor
present in the installation on screen Cag12
Not present Automatic
- Check evaporator confi guration on screen Eab00 and following Hecu side (number of
evaporators, size, type of control installed,..)
- Check FBus connection (connections, wiring, polarity,...)
- MPXPRO / UC status (check control side confi guration, serial address H0 parameter, if
necessary re-confi gure fi rst)
Not present Automatic
