8 Maintenance

The controller does not require any maintenance. It does not have any fuses so, if brief voltage spikes occur, the refrigeration system will not stop operating for a prolonged period. Once the disturbance has passed, the controller will automatically start up again.

Cleaning the housing: Only a dry anti-static cloth may be used to wipe clean all plastic parts. Do not use water or cleaning agents containing solvents!

9 Alarm messages

If an alarm occurs, the alarm output will be activated and on the display a code will alternate with the cold store temperature.

Display

Meaning

AL1

Program memory data loss.

 

The preset values will be used as an emergency program.

 

The setpoint value will be set to +4 or –18 °C,

 

depending on the selection of DIP switch 1.

AL2

Limit value (=setpoint value +E03) at sensor T1

 

exceeded and delay time E04 elapsed.

AL3

The sonsor temperature at sensor T1 is above

 

50 °C or below –55 °C.

AL4

The specified setpoint value is outside

 

the limits E12 and E13

AL5

Cold store temperature sensor T1 – short

 

circuit or break in wiring. Compressor switches

 

as a function of parameter E17.

AL6

Evaporator temperature sensor T2 – short

 

circuit or break in wiring.

 

Safety times are used, for the fan run-on function

 

the fan is controlled with the compressor by the

 

evaporator fan control E11 automatically

 

switching from 3 to 1.

 

After sensor T2 has been repaired,

 

E11 must be reset manually from 1 to 3.

AL7

For PCR-300RC only: Real-time clock faulty,

 

switching over to interval defrosting (interval = 4 hours)!
