4.4 Error messages
The error numbers are not displayed for units with standard controllers: With the ECoolPLANT software error
numbers can be read on the computer.
 The blinking of the red LED light on the controller circuit board is not a fault indicator or error message. The red
LED light indicates that voltage is supplied to the cooling unit.

Unit activity Possible causes
• Door contact:
Blinking
• The door contact loop has
OFF
been interrupted.
OFF
OFF
Closed
• Pressostat tripped:
Blinking
• Excessively high pressure
OFF
has built up in the
ON
refrigerant circuit. The
cooling unit cannot
OFF
dissipate the heat from the
Open
refrigerant circuit.
• Phase sequence / phase
Blinking
OFF
loss:
• Failure of at least one phase
OFF
or phase sequence is
incorrect (only with
OFF
alternating current units
Open
with rotating piston
compressors).
• Sensor 1 (TS1) defective.

Corrective measures
▪ Close door.
▪ Connect door contact
switch.
▪ Bypass door contact.
▪ Check wiring.
▪ Allow the unit to cool
down.
▪ Clean the heat
exchanger fins
(internal/external).
▪ Check condenser fan
(external) for function.
▪ Check the field of
rotation - (clockwise
rotation is required).
▪ All phases must carry
rated voltage.
▪ Replace Sensor 1
(permanently soldered
on the controller circuit
board) or the overall
controller circuit diagram
according to the unit
type.
