If the fan function is switched ON, the external fan starts to operate when
the set value P06/pressure line temperature TS3 is exceeded, and it remains
2....10
2 K
in operation till the value is below the hysteresis level (P07).
If the cooling system is switched OFF or if faults occur, the external fan
0....10

remains in operation until the expiration of the programmed delay time, in
order to cool the vaporizer.

If the differential temperature pressure value TS3 – ambient temperature - is

in operation.

If the temperature at the suction line TS2 falls below this parameter value,
alarm A04 is released and the compressor is switched off. However, the
-5....+10

error evaluation starts only 3 minutes after the start of the cooling system. If
the parameter value is exceeded by 5K, normal conditions are sensed.
If an alarm occurs, the assigned relays are switched off with delay. However,

the display and perhaps the disconnection of the compressor are effected
immediately.

If the difference between the internal cabinet temperature TS1 and the
temperature suction line TS2 is below this limiting value, alarm A06 is

released. The cooling system remains in operation. The error evaluation
however, is only effected 3 minutes after the start of the cooling system.
The temperature of the suction line TS2 is shown for 50 sec. on the display.
The temperature of the pressure line TS3 is shown for 50 sec. on the display.
The ambient temperature TS4 is shown for 50 sec. on the display.
