LOW SUPPLY
PRESSURE
Supply Air
Pressure to IVT
is below Low
Alarm Setting
(25PSI –
1.7BAR) 1. Check supply air pressure at the source, compare to IVT supply pressure
reading. To obtain the Supply Air Pressure reading at the IVT, press Sup Air
Pres key.
2. If the IVT supply air pressure reading is lower than the pressure reading at the air
source, check for any shut-off valves installed within the supply airline to the IVT.
Confirm these valves are in the full open position.
3. Check air filter element F-1. A dirty or clogged filter element will result in a
difference in pressure readings from the air source to the IVT. Change filter
element if necessary. CFH-RS part no. 77780124.
4. Increase supply air pressure at the source above Low Alarm Setting (25PSI –
1.7BAR).
HIGH SUPPLY
PRESSURE
Supply Air
Pressure to IVT
is above High
Alarm Setting
(150PSI –
10.3BAR) 1. Check supply air pressure at the source, compare to IVT supply pressure
reading. To obtain the Supply Air Pressure reading at the IVT, press Sup Air
Pres key.
2. Reduce supply air pressure at the source below High Alarm Setting (150PSI –
10.3BAR).
HIGH AIR
CUTOFF AIR
TEMPERATURE
Heated Air
Temperature is
above High
Cutoff Alarm
Setting
(150
°
F - 65
°
C)
Note: High Air
Cutoff alarm is
designed to act
as a failsafe
feature for the
Air Heater
Element. The
temperature
sensor that
controls the high
air cutoff alarm
is separate from
the sensor used
to control air
temperature.
1. Confirm that the Air Heater Set temperature (120
°
F - 49
°
C) is below high air
cutoff alarm setting (150
°
F - 65
°
C). See the IVT Operating Instructions for
instructions on how to program user specified alarm and control set point values.
Note whether customer assigned values have been programmed to the replace
the factory values. To check air heater high cutoff temperature press key
combination
Set , Air Temp. Press the Enter key three times to view high cutoff
alarm setting. Press Clear key to return to normal operating mode.
2. Press Air Temp key. If temperature measurement is low (90
°
F - 100
°
F), the
sensor TE-2 that controls air temperature is failing and should be replaced. CFH-
RS part number 77700941.
3. Check the operation of the Air heater solid state relay SSR-1. Open AC electrical
enclosure, and observe the LED located on the SSR-1. The LED indicates the
operating status of relay. When LED is ON the air heater element is energized.
When LED is OFF the air heater element is de-energized. Confirm LED is OFF
when air temperature at or above control set point.
If the air temperature is above the control set point and the relay SSR-1 is ON,
replace the relay. CFH-RS part number 77780152.
4. If repair is not possible, switch mist generation to Auxiliary. See procedure
located on interior of IVT cabinet door.
