PARAMETER
NAME
SET TO COMMENTS
Proportional
Band
11
Sets the bandwidth of the proportional control function
to ± 11% of full scale
Integral time
10
Sets the reaction time for the proportional control
function to 10 seconds.
Derivative Time
7.7
Sets the reaction time for the derivative control
function (which reduces overshoot) to 7.7 seconds.
Low Alarm Limit
950
Sets the low alarm point to 950˚C
High Alarm Limit
1050
Sets the high alarm point to 1010˚C
Cycle Time
2

between On and Off) for 2 seconds.
EXAMPLE: for a duty cycle of 25% with a Cycle time of
2 seconds, the controller will turn the heater on for 0.5
seconds every 2 seconds
Hysteresis
3
Sets the bandwidth of the area around the set point
where the controller will not try to change the process
value (thereby inducing unnecessary fluctuations) to 3
% of full scale.
Autotune
0 (OFF)
Autotune is OFF
Parameter Lock
Can be either
0
