Algorithm of operation of the dryer components
When turning on and off the dryer, the actuators have delays and sequence in starting and
stopping
:
•
manual start of the dehumidifier by selecting the MAN or AUTO mode on the 3-position
switch
;
•
start of the regeneration air fan and the rotor motor-reducer
;
•
start of the working air fan (depends on the selected mode and the set air humidity level)
;
•
starting the regeneration air heater
;
•
operation of the dehumidifier in steady state
;
•
for the AUTO mode: when the set humidity is reached, the regeneration air heater and
the working air fan are automatically switched off (the regeneration air fan and the rotor
motor-reducer continue to work until the air temperature after the heater drops to 60°C),
then the process of automatic start of the components is repeated
;
•
manual shutdown of the dehumidifier by selecting the OFF mode (middle position)
on the 3-position switch
;
•
switching off the regeneration air heater and the working air fan (the regeneration air fan
continues to operate until the air temperature after the heater drops to
60°С);
•
shutdown of the regeneration air fan and rotor gear motor
.
Starting and turning off the heater during the operation of the dehumidifier can be monitored
by changes in the readings of the ammeter (for the AD-200 model) or the temperature
controller (for the AD-400 model
).

High humidity warning
(
default value is
85%)
The dehumidifier will give an alarm if the current
relative humidity reaches set value or higher.
Under normal operating condition, the dryer
should quickly reduce the level humidity. If the
relative humidity level cannot be quickly reduced
below the SdH value, the dryer is in trouble and
needs to be checked.
