CODE
TYPE OF ERROR
CONSEQUENCE
of ERROR only on
Chiller 1 (Master)
CONSEQUENCE
of ERROR only
on Chiller 2
to 8 (Slaves)
RECOMMENDED ACTIONS
E-48
Error in the DC
bus voltage.
Models 380/440V:
Shuts off the Inverter
compressor
NA
Check/correct:
Board supply voltage. Connection
between board and compressor.
Voltage on components - reactor and capacitor.
Reference range: 350VDC to 650VDC.
Replace the board if required.
Error in the
compressor board
(Communication
between
processors)
Models 220V: It only
turns off the inverter
compressor.
NA
Check/correct:
Board supply voltage. Connection on the board.
Ground conditions.
Replace the board if required.
E-49
High temperature
in the compressor
board heatsink.
Models 380/440V:
Inverter compressor
won’t start
If the compressor is
running, it will shut
down, returning
after the heatsink
temperature has
been reduced.
NA
Check/correct:
Heatsink temperature (maximum 80°C).
Obstruction of airfl ow in the sink (dirt).
Fan speed
If the problem is in the sensor,
replace the board.
Error in
communication
between the
compressor board
and main board.
Models 220V:
Inverter compressor
won’t start
If the compressor is
working, it will shut off .
NA
Check/correct:
Communication between boards.
Reference value: 0VDC to 5VDC.
Replace the board if required.
E-50
High fan
current
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Fan supply voltage. Damage to the propeller.
Replace the board if required.
E-51
High current on
fan board module
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Fan supply voltage. Replace
the board if required.
E-52
Motor locked out
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct: Damaged motor.
Replace the component(s) if required.
E-53
No phase on
fan motor.
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Connection between board and fan.
Voltage on components - reactor and capacitor.
Replace the board if required.
E-54
Low fan motor
speed
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Hall sensor hall connection on
motor board. Supply voltage
Check whether the condenser middle
sensor is correctly connected.
Disconnect and measure the sensor
ohmic resistance (250C - 10kΩ).
Replace the component(s) if required.
