6.12 Blast chilling/deep freezing intensity
The device can manage the phase cut speed regulator for EVDFAN1 single phase fans (to be ordered separately); see
paragraph 15.1 “phase cut speed regulator for EVDFAN1 single phase fans”.
The regulator can be used to manage evaporator fan activities with a single analogue control, i.e. via the PWM
analogue output of the device and the regulator phase cut output (the digital output K3 is however activated).
Parameter F0 must be set at 3.
Parameters F18... F22 establish speed 1... 5 of the evaporator speed (intended as a percentage of the maximum
speed), parameter F23 establishes the speed at which the evaporator fan is switched on during post blast chilling
storage and parameter F24 establishes the speed at which the evaporator fan is switched on during post deep freezing
storage (the latter intended as one of the speeds 1... 5).
The following table illustrates the speeds at which the evaporator fan is switched on during the operating cycles.
A different speed can be selected using the procedure given in 6.12.1 (intended as one of the speeds 1.. 5) in
temporary mode (i.e. if a power cut occurs, on restore of the same the speeds illustrated in the following table will be
offered), except if the selection is made before starting a blast chilling and storage cycle or before starting a hard blast
chilling and storage cycle or before starting a soft deep freezing and storage cycle (in this case the speeds are
memorised instead).
