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.
