Code Message Information
Warning Fault Possible causes Remedy
W71 ––– Low conductivity If the cylinder has had reduced operating capacity and excessive high water sen-
sor activations before the break-in period of the cylinder has expired the system
will generate a low conductivity warning instead of a spent cylinder notication.
This will allow decrementation of the high water sensor counter for a period of
operating time before generating a spent cylinder code.
Wrong cylinder type installed Install steam cylinder for low conduc-
tivity.
Cylinder receptacle leaking. Check/seal/replace cylinder recep-
tacle.
Supply water has too low water con-
ductivity.
Connect water supply with water
conductivity in admissible range.
––– E84 Driver fault No communication between the controller and the driver board
Driver board defective. Let have the driver board be replaced
by an electrician.
Driver board ID wrong. Check rotary switch SW1 on the driver
board and set correctly (0 for cylinder
A, 1 for cylinder B).
Communication cable between the
driver board and the control board
not connected properly
Make sure the RS485 cable is con-
nected to RS4851 on the driver board
and J12 on the control board.
Wrong version of driver board. Contact your Condair representative.
W125 ––– Capacity Timer The capacity limitation is currently controlled via Capacity Timer function.
The Capacity Timer is active and has
over ridden the normal operation.
No action is required.
W126 ––– Setpoint Timer The setpoint is currently controlled via the Setpoint Timer function.
The Setpoint Timer is active and has
over ridden the normal operation.
No action is required.
––– E128 Current Sensor Current sensor not able to be calibrated on system start-up.
Current sensor not able to be calibrated
on system start-up
Contact your Condair representative.
––– E130 Current Circuit Current monitoring circuit has detected that current has exceeded maximum
allowable current.
Current coils disconnected or not func-
tioning.
Check wiring between current coils and
driver board.
One of the phases is disconnected. Check fuses, wiring to humidier, and
supply voltage is present on all phases.
Electrode plugs on cylinder not con-
nected.
Check that all Electrode plugs are
properly connected and that wiring is
secure to contactor.
Inlet valve stuck open. Check that the inlet valve is closed,
after full output is reached. If not,
check/Replace inlet valve if neces-
sary.
Drain pump is blocked preventing drain
to dilute cylinder water.
Check that water drains correctly
from cylinder when manual drain is
activated. If not, check/Replace drain
pump if necessary.
––– E131 Missing Coil One of the current coils used for monitoring the humidiers current is not detected.
Current coil is not connected. Check/connect wires between current
coils and driver board.
