no. Relay name Description if START/STOP is pressed.
R 1
Main contactor K1 The relay energizes via X9.2 the main contactor K1. If the
Start/stop button is pressed the relay is switched off! (Normally
on)
R 2
Fan on/off or D0
signal for frequency
controller Electric version (Contactor controlled fan):
The relay energizes via X9.3 the fan motor. Between is relay K4
(Entry X9.7, responsible for the direction). The fan runs in left
direction.
Gas version (Frequency inverter controlled fan):
The signal D0 (120-230V) from X9.3 goes into the entry D0 of
the controller. The fan runs in left direction.
R 4
Fan left /right This is a potential free relay which switched the fan contactor K4
via X9.6 (n.o.) alternatively via X9.5 (min.). The supply power
comes from relay 2. The fan does not run!
(No power from relay 2).
R 8
Air flap (option) The relay energizes via X10.4 the lift magnet in the fresh air pipe.
The valve (flap) opens if activated.
r10
DynaSteam Activation of the DynaSteam steaming unit, via X8 (24V) . This
is a short cut proof, on board solid state relay. The relay works
together with relay 11 and in this procedure every second the
relay is activated for on second to produce a water flow. In two
chamber units (20.x) two DynaSteam units are connected parallel.
R11
DynaSteam See above
r12
Drain solenoid The relay energizes via X9.8 the drain solenoid valve.
R13
Buzzer
The relay energizes via X10.2 the buzzer H13.
r14
Gas on 1
(Only gas version)
Ignition controller N10 via X4.4 The glow plug R10 is activated.
