PARAMETER
NAME
SET TO COMMENTS
OFF
0
Sets the controller to reverse action (hotter
temperatures = less heating; lower temperatures =
more heating) and turns off the heater should the
thermocouple input fail.
Input type
(Refer to
COMMENTS,
this row)
You may have one of three thermocouple Types; the
wire colors distinguish which one you have:
red & black (Type S): set to 6

to 40˚C
Upper input range
limit
1100
Sets the upper end of the controller full scale
bandwidth to 1100˚C
High Alarm Type
10
Sets the High alarm point to trigger when the process
value exceeds the high alarm set point only after the
process value rises above the lower limit for the first
time after power up
Low Alarm Type
10
Sets the Low alarm point to trigger when the process
value exceeds the high alarm set point only after the
process value rises above the lower limit for the first
time after power up
Alarm Hysteresis
3
Sets the hysteresis bandwidth for both alarm points to
3% of full scale.
Decimal Point
