ATTENTION!
THE APPLIANCE WON'T START IF THE „SCHALTER REG-HEIzUNG"
IS NOT INTO POSITION 1.

. This.running-on.is.terminated.automatically .
-..it.is.possible.to.restart.the.dryer.during.running.on .
-..the.dryer.should.only.be.switched.off.by.the.main.switch.installed.in. .

Function of the electric air heater
The.heater.consists.of.3.individual.stages . . This.results.in.an.increase.
in.the.temperature.of.the.regeneration.air.to.approx . . 120°C,.which.is.
necessary.for.the.regeneration.of.the.dryer . . Two.heating.stages.are.
always.switched.on.as.basic.load.stages .
If.the.full.regeneration.energy.is.not.required.for.the.drying.procedure,.
then.the.control.thermostat.(5B1).switches.the.control.stage.off.de-
pending.on.the.regeneration.exhaust.air.temperature . . The.regenerati-
on.temperature.is.then.reduced .
The.thermostats.are.marked.separately.and.are.accessible.by.opening.
the.service.doors .

06. Triggering of the safety devices and messages

Motor faults
If.the.motor.protection.breaker.for.the.regeneration.air.fan.trips.due.to.
an.overload,.then.the.dehumidifier.will.be.switched.off.automatically . . If.
the.motor.protection.breakers.for.the.process.air.fan.and.the.rotor.drive.
trip.due.to.an.overload,.then.the.dehumidifier.will.continue.in.running-on.
mode . . The.'Motor.fault'.indicator.lamp.lights.up . . Following.rectification.of.
the.fault,.the.black.reset.button.on.the.motor.protection.breaker.must.be.
pressed.again.and.the.fault.must.be.unlocked.with.the.reset.button.4S1 .
Thermostat faults
If.the.safety.or.maximum.thermostat.switches.off.due.to.over-tem-
perature,.then.the.'Thermostat.fault'.indicator.lamp.lights.up . . In.or-
der.to.restore.the.standby.condition.of.the.dehumidifier.after.cooling.
down,.proceed.as.follows:
-..Press.the.red.reset.button.on.the.maximum.temperature.limiter. .
. 4F2.and.on.the.safety.thermostat.4F1 . . Subsequently.acknowledge. .
. with.the.reset.button.4S2.on.the.control.cabinet .
Electric heater faults
The.individual.heating.stages.of.the.regeneration.air.heater.are.pro-
tected.by.over-current.trips . . In.the.event.of.a.short.circuit.or.over-
loading,.the.heating.stage.concerned.is.switched.off.and.the.'Heater.
fault'.lamp.lights.up . . After.rectifying.the.fault,.the.black.reset.button.
on.the.overcurrent.trip.must.be.pressed.again.(unlocking) .

Standby

The.electrical.power.is.connected.to.the.dehumidifier,.the.rotary.field.
of.the.mains.supply.is.correct.and.there.is.no.error . . The.dehumidifier.
can.be.switched.on.via.button.5S1 .
