Warning Fault
W42 – RH High Warn -
ing
Sensed humidity is above the RH High value configured in the control software. The unit
will remain idle until the sensed RH value drops below the setpoint value.
Incorrect layout of the humidifier control system (sensor location too close to steam
distributor or other sources that affect measurement), or defective components.
– Check the humidifier control system.
Humidifier capacity too large for the space being humidified.
– Limit the output capacity of the humidifier – refer to Manual Capacity .
– Adjust the Proportional / Integral value of the controller.
The RH High value for the sensor signal may be set too low.
– Adjust the RH High value for the sensor signal.
W43 –
RH Low Warning Sensed humidity is below the minimum value configured in the control software. The unit
should continue operating unless it is in standby mode.
Incorrect layout of the humidifier control system (sensor location too close to steam
distributor or other sources that affect measurement), or defective components.
– Check the humidifier control system.
The RH Low value for the sensor signal may be set too high.
– Adjust the RH Low value for the sensor signal.
Unit may be in standby mode.
– Check the safety loop is closed, and that all burners are operational.
– E46
Drain Check The drain pump has been active for an extended period of time without the water level
changing in the float chamber. The unit needs to drain for optimal performance. Fix the
problem before restarting the unit.
Back pressure in the drain line may be causing slow drain.
– Remove any blockages in the drainage system.
Loose connection.
– Check the connections between the float board and the driver board, as well as the
drain pump.
Floats may be stuck.
– Visually check that the different LEDs on the float board light up as the water level in
the float chamber changes. If necessary, clean the float chamber – refer to "Cleaning the
Float Chamber" on page 53 .
Drain pump may be clogged.
– Clean the drain pump – refer to "Cleaning Hoses, Dual Fill Valves and Drain Pump" on page 54 .
W52 –
Float Inconsist -
ent
On unit startup the float levels do not rise logically from low water level L1 (red LED) to
high water level L5 (yellow LED).
Excess back pressure in the steam line.
– Check the steam line.
Float level sensor may be malfunctioning.
– Inspect all hoses and connections.
– Clean the float chamber – refer to "Cleaning the Float Chamber" on page 53 .
W57 – Startup Code Activation code required to use the humidifier.
Activation code missing.
– Contact your Condair representative.
– E84 Driver Board
Fault
No communication between the integrated control board and the driver board.
Dip switch settings are not correct.
– Verify dip switch settings.
Communication cable between the
driver board and the integrated control board
not connected properly.
– Make sure the RS485 cable is connected to J15 (RS4851) on the driver board, and
J12 on the integrated control board.
– With the unit powered up, check that LED1 and LED10 on the driver board are flash -
ing. Otherwise, contact your Condair representative.
Unspecified driver board fault.
– Check that the heartbeat LED10 on the driver board is blinking. Otherwise, contact
your Condair representative.
