(*2) 15 minutes at device start-up, 60 seconds during normal operation
(*3) 15 minutes at device start-up, 600 seconds during normal operation
(*4) 0 seconds at device start-up, 2 seconds during normal operation
Cause
Transducers BHP and BLP, low
differential pressure between
values HP and LP
Transducer BLP, the evaporating
pressure of the refrigerant fluid is
too high.
Transducer BHP, the condensing
pressure of the refrigerant fluid is
too low.
Relay RPP, power phases L1, L2,
L3 are connected to the device
with the uncorrect phase
sequence.
Missing power phase.
The internal heat protection of
cooling fan has triggered.
The circuit breaker QV1 has
triggered.
Communication broken between
User Interface and Electronic
Control Unit

Action
Refer to section "16.2 Specific
malfunctions" on page 114,
"Transducers BHP and BLP, low
differential pressure between
values HP and LP".
Refer to section "16.2 Specific
malfunctions" on page 114,
"Transducer BLP, evaporating
pressure of refrigerant fluid too
high".
Refer to section "16.2 Specific
malfunctions" on page 114,
"Transducer BHP, condensing
pressure of refrigerant fluid too
low".
Restore the correct phase
sequence
Connect the missing phase
Wait 30 minutes to cool down
the motor then check carefully
the operation of cooling fan.
Restore the circuit breaker QV1
then check carefully the
operation of cooling fan, models
RA 2400 / 3000
Check the integrity of HMI
