LOW OIL TEMP
Bulk Oil
Temperature is
below Low
Alarm Setting
(10
°
F - -12
°
C)
1. Confirm ambient temperature is above Oil Temp Low Alarm Setting.
2. If minimum ambient temperatures in geographical location fall below 15
°
F/10
°
C,
IVT unit should be equipped with Air Pre-Heater option.
HIGH OIL TEMP
Bulk Oil
Temperature is
above High
Alarm Setting
(160

F – 71
°
C)
1. Confirm ambient temperature is below Oil Temp High Alarm Setting.
2. If maximum ambient temperature in geographical location exceeds 140
°
F/60
°
C,
IVT unit should be equipped with Air Cooling option.

Low Alarm
Setting
(100
°
F - 38
°
C)
1. Confirm that the operating air temperature is above Low Alarm Setting (100
°
F –
38
°
C), and that the Air Heater Set temperature (120
°
F - 49
°
C) is above low alarm
setting.
The operating air temperature is normally displayed on the controller readout
during operation. To check air heater set temperature press key
Set
, the rightmost
digit will display “1”
.
The displayed value is the set temperature for the air heater.
Normal operation of controller display will automatically resume after 10 seconds.
2. Check the regulated air pressure being supplied to the auxiliary unit mist head.
The minimum regulated air pressure is 10 PSI. Increase pressure above interlock
setting 10PSI - .69BAR.
The IVT Auxiliary Controller will not permit the air heater element to energized if
the regulated air pressure is below interlock setting 10PSI - .69BAR. A low air
pressure switch is utilized to provide the interlock contacts. The switch contacts
are arranged to close on increasing pressure. Verify that the pressure switch
operates at 10 PSI, and replace if it is malfunctioning.
3. Check the operation of the Air heater element H-2 and solid state relay BU-SSR-1.
Open the electrical enclosure to auxiliary unit. and observe the green LED located
on the BU-SSR-1 relay. The LED indicates the operating status of relay. When
LED is ON the air heater element is energized. Confirm that the LED is lit when air
temperature is below control set point (120
°
F - 49
°
C)
4. If relay LED is on and the air temperature is not increasing, replace the 10A fuse at
fuse block number #2. CFH-RS part no. is 77780155. If IVT is a 240VAC, the 10A
fuse at number #5 should also be replaced. If the Air temperature is below the
control air temperature setting, replace the SSR-1 relay if the green LED remains
OFF.
5. If the fuses and the solid state relay are functional, check and replace the heater
element if necessary.
Display reads
“EEEE”
Thermocouple
lead is loose or
disconnected
1. Confirm which thermocouple is generating “EEEE” reading. Check wiring into
controller. Reference electrical wiring diagram.
2. Replace suspected thermocouple if necessary. CFH-RS part number 77700941
