on Chiller 2 to
8 (Slaves)
RECOMMENDED ACTIONS
E-55
Overload on
fan start
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Connection between board and
fan. Voltage on components
Replace the component(s) if required.
E-56
Error on Hall
Eff ect sensor
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Hall sensor hall connection
on motor board.
Replace the component(s) if required.
E-57
Error in the
fan board
It only turns off the indicated unit.
Check/correct:
Fan supply voltage. Connection
on the board.
Replace the component(s) if required.
E-58
Error in DC
bus voltage on
fan board
It only turns off the indicated unit,
resetting automatically after the voltage
returns to normal parameters.
Check/correct:
Board supply voltage. Connection
between board and fan.
Voltage on components -
reactor and capacitor.
Replace the component(s) if required.
E-59
High temperature
on module of
fan board
Shuts off only the faulty unit, resetting
it automatically after 1 min.
Check/correct:
Board supply voltage.
Replace the component(s) if required.
E-60
Error on processor
It only turns off the indicated unit.
De-energize the unit and re-energize it
If the problem persists, replace
the component(s).
E-65
Pressure
diff erential error
between the
inlet and outlet
water. Required
for systems with
more than 3
modules (> 45TR)
Turns off the system.
The system does not reset automatically if
the error repeats 3x in less than two hours.
Check/correct:
Water fl ow in the system.
If the pressure switch (DPS)
is on in the master unit.
DPS contact is opening and
closing - operational?
If the system has three units or less
and DPS is not used, make sure that
the setting is OFF in control.
E-66
Room temperature
error <5 ° C and
crankcase resistor
Turns off the compressors.
The unit must not operate at temperatures
below 5 ° C. If the temperature is above
5 ° C, check the electrical connection
and physical connection of the room
E-67
Unit water low
outlet temperature
(ULWT). Freezing
protection
on cooler
It only turns off the inverter compressor.
The system does not reset automatically if
the error repeats 3x in less than two hours.
Check/correct:
Outlet water temperature sensor
Water fl ow below the minimum
limit for Dirt in Y fi lter.
