4.6 Error messages
On devices with the X-Series Premium Controller, error numbers are shown on the LCD display. With the
ECoolPLANT software it is possible to read the error numbers 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.

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 or the
controller circuit board
according to the unit
type.
▪ Replace controller circuit
board if the sensor is
soldered in place.
