No control sensors

Fatal 

Alarm

Description

Supply Air Sensor 1, Supply Air Sensor 2, Return Air Sensor and Evaporator 

Sensor are all malfunctioning. 

Cause

Alarm indicates that all control-relevant sensors are defective or unreliable. See 

also 

Temperature control

 and 

Expansion valve control

 p.18

Trouble 

shooting

Possible causes:

• 

Supply Air Sensor 1, Supply Air Sensor 2, Return Air Sensor and 

Evaporator Sensor are all malfunctioning.

• 

X1 cable is defect.

• 

Controller PCB defective.

Accompanied alarms:

• 

AL 100 to AL 108.

Trouble shooting:
1)  Verify all other sensor alarms AL 100 to AL 3XX and try to remove these 

alarms.

2)  If this alarm remains active, replace main controller.

Elimination

When one of the control sensor values enters into the valid area, it is again possible to 

control container temperature. For reliability reasons at least one of the control sensor 

values must be valid for 30 sec. before sensor may be used as control reference again.
