Code Message Information
Warning Fault Possible causes Remedy
––– E95 No Heating voltage Heating voltage missing although a demand is present.
Note: As soon as the heating voltage is present again, the Condair RS continu-
ous normal operation.
Main contactor defective. Let have the main contactor be checked/
replaced by an electrician
Phase failure heating voltage supply. Check/switch on electrical isolator in the
mains supply line. Let have fuses in the
mains supply line be checked/replaced
by an electrician.
––– E97 ** Ext. 24V Supply External 24 V supply faulty. Voltage too high or too low.
Fuse "F2" on the driver board defec-
tive.
Replace fuse "F2" on the driver board.
Short circuit on external connection. Remedy short circuit.
Overload on external connection. Disconnect load on terminal X16.
––– E98 ** Ext. 10V Supply External 10 V supply faulty. Voltage too high or too low.
Fuse "F2" on the driver board defec-
tive.
Replace fuse "F2" on the driver board.
Short circuit on external connection. Remedy short circuit.
Overload on external connection. Disconnect load on terminal X16.
––– E100 ** IO Inlet 1 Fault on inlet valve 1.
Valve electrically not connected or coil
defective.
Correctly connect valve or replace coil .
––– E101 ** IO Inlet 2 Fault on inlet valve 2 (only on units with increased control accuracy).
Valve electrically not connected or coil
defective.
Correctly connect valve or replace coil .
––– E111 ** IO Drain 1 Fault on the optional drain water cooling valve.
Valve electrically not connected or coil
defective.
Correctly connect valve or replace coil .
––– E112 ** IO Drain 2 Fault on the optional drain valve of the scale collector tank.
Valve electrically not connected or coil
defective.
Correctly connect valve or replace coil .
W120 E120 ** Fill time min. If the minmum ll time is underrun the Condair RS carries out a level test. This
procedure is repeated three times if minmum ll time is underrun again, then a
fault message is triggered and humidication is stopped!
Level unit is scaled. Clean level unit.
Hose connections from the level unit
to the steam cylinder are clogged.
Check hose connections from the
level unit to the steam cylinder and
clean if necessary.
W121 E121 **
Max.vaporization
time
If the maximum vaporization time is exceeded the Condair RS carries out a level
test. This procedure is repeated three times if maximum vaporization time is
exceeded again, then a fault message is triggered and humidication is stopped!
Individual heating elements faulty. Replace faulty heating elements.
Fuses on the power board defective. Let have fuses on the power board be
replaced by an electrician.
Mains voltage too low or failure of a
phase (L1, L2 or L3).
Let have the mains voltage and con-
nections be checked by an electrician.
Steam lead too long or not insulated. Maintain maximum steam line lengths
(max. 4 m), Insulate steam line.
This error may also occur upon a cold
start
Enable Soft start function.
E124, E200,
E201, E210
––– See malfunction list in the Condair RO-A installation and operation manual.
––– E300 Blower security
contact open
Enable contact of the blower pack open.
No voltage supply to blower pack pre-
sent.
Check/correctly connect cabling to
blower pack.
Operation without blower pack: jumper
wire "J1" not connected to terminal block
"X12" on driver board.
Connect jumper wire "J1" to terminal
block "X12" on driver board.
** These fault messages must be reset by switching the Condair RS off and on again (see chapter 7.5)
