Indicates that the airflow sensor is open. Verify that the signal from the airflow sensor
AirFlow
is present at the controller's input on the PCB and verify wiring.
Indicates that the high limit item is open. Verify that the signal from the supply high
limit sensor is present at the controller's input on the PCB and verify wiring.
SupplyHighLimit If the high limit cutout has been activated due to a humidity reading that exceeds the
high limit setpoint, ensure that high limit humidistat is operating correctly and that the
distance between the sensor and the steam dispersion manifold is sufficient (4.6 m).
Indicates that the interlock and the cut-out circuitry are open. Verify that the signal
from the interlock sensor is present at the controller's input on the PCB and verify
Interlock
wiring.
Indicates that the thermal cutout sensor is open. Verify that the signal from the
thermal cutout sensor is present at the controller's input on the PCB and verify wiring.
ThermalCutout If that the high temperature switch has been activated due to an abnormal
temperature reading, ensure that the humidifier is not operating below standard water
level and verify the operation of the water level sensor.
Indicates that the capacitive water level sensor is defective or incorrectly wired. Check
WaterLevel
sensor and verify wiring.
Indicates that the resistive low water level sensor is defective or incorrectly wired.
WtrLvlLow
Check sensor and verify wiring.
Indicates that the resistive high water level sensor is defective or incorrectly wired.
WtrLvlHigh
Check sensor and verify wiring.
Indicates that the evaporation chamber water temperature sensor is defective or
WaterTemp
incorrectly wired. Check sensor and verify wiring.
Indicates that the foam cutout sensor is defective or incorrectly wired. Check sensor
FoamCutout
and verify wiring.
Indicates that the solid-state relay temperature sensor is defective or incorrectly wired.
SSRTemp
Check sensor and verify wiring.
Indicates that the printed circuit board fuse sensor is defective or incorrectly wired.
ContactorsFuse
Check sensor and verify wiring.
Indicates that there was an error during draining due to a pump failure. Verify that the
FailedPump
drain pump is operating correctly and that it is not being hindered or obstructed.
Indicates that the water level sensor has not reached the desired value within the
FillTimeout programmed delay. Verify and remove any obstructions in the water inlet line and
verify that the shut-off valve is not closed.
Indicates that there was an error during draining due to a blockage in the pipes. Verify
BlockedPiping and remove any obstructions in the piping and ensure that the drain outlet is not
clogged.
Indicates that the water temperature in the evaporation chamber has not reached the
HeatTimeout
boiling point within the programmed delay. Verify the temperature of the supply water.
Indicates that the evaporation chamber temperature sensor has detected a
Overheat temperature reading greater than or equal to 105°C. Verify the operation of the water
level sensor and ensure that the water supply piping is not obstructed.
Indicates that a water leak has been detected. Verify the water line for signs of leaks
WaterLeak and ensure that all piping and water connections have been properly installed and
secured.
Indicates that there is a problem with the SDU fan. Verify the signal and the operation
FanFault of the SDU fan.
(Only applicable for humidifiers having the SDU option.)
Indicates that the due date for servicing the evaporation chamber has arrived. See
ServiceDue
Service section on page 52 for details.
