Problem Probable Cause
Humidifier will not produce
steam, or does not reach RH
setpoint value.
Safety loop is open.
– Check if the message “Safety Loop” is displayed in the operating status area of the Home
screen.
– Check if there is 24 VAC supply at low voltage terminal strip pin “2”.
– Check that all On/Off devices connected to low voltage terminal strip pins “1” and “2” are
wired properly, and their contacts are closed when they should be.
Output is limited by the high limit humidistat signal.
– Check if the high limit humidistat is installed too close to the steam distributor. The recom -
mendation is five times the absorption distance or minimum 3 m. Check the setpoint value
for the high limit – typically set at 80% RH.
No signal on Channel 1.
– Check voltage between low voltage terminal strip pins “3” and “4”. For a demand signal
configuration, the signal must be 27% of full scale signal for the humidifier to start. For a
transducer signal configuration, the signal must be lower than the setpoint value for the
humidifier to start.
No signal on Channel 2 (on units with Control Channels set to "Dual").
– Check voltage between low voltage terminal strip pins “3” and “5”. For a demand signal
configuration, the signal must be 27% of full scale signal for the humidifier to start. For a
transducer signal configuration, the signal must be lower than the setpoint value for the
humidifier to start.
Capacity has been manually limited.
– Check/adjust Manual Capacity , if necessary.
Humidifier displays warning
or fault message.
The control software has detected an abnormal condition.
– Refer to "Warning and Fault List" on page 60 .
7.4 Warning and Fault List
Table 14 shows the list of warning and fault messages triggered by the control software in the humidi -
fier, and the corrective actions. The warning code escalates to a fault code if the alarm condition is not
resolved within a certain period of time. After fixing a fault condition, reset the fault status as described
in "Resetting Fault Status" on page 66 .
