1. FSH - Full Scale High
2. FSL - Full Scale Low
3. OFF- this will deactivate the alarm relay
TO ACKNOWLEDGE / RESET THE ALARM RELAY:
The alarm relay is FM approved and must be manually acknowledged. Once the process variable has
returned to a safe value and the alarm is acknowledged the relays will automatically reset. The alarm
can be acknowledged by pressing the PAGE button.
TO CHANGE ALARM SET POINTS:
NOTE:If set point is shown in the lower display just press the UP and DOWN arrows. If it is not shown

NOTE: Set Limit Controller Set Point at 20
° F over maximum operating temperature.
•Electric Drum Heating Cabinets: 300
° F + 20 ° F = 320 ° F.
•Steam Drum Heating Cabinets: 300
° F + 20 ° F = 320 ° F.
