The PAGE-10 lists Alarm and Control related parameters for Temperature. The Table 4.1 below describes each parameter.
Table 4.1
TEMPERATURE PARAMETERS
Parameter Description
Settings
(Default Value)
0 to 1000 Seconds
(Default : 100)
(Default : 5.0)
0.1 to 999.9°C
INTEGRAL TIME
Sets integral time constant in seconds for temperature control
loop. Setting the value to 0, cuts-off the integral action.
PROPORTIONAL BAND
Sets proportional gain (% power per unit error) for temperature
control loop. Defined in same units and resolution as that for PV.
(Default : 0.5)
0.3 to 25.0°C
(Default : 0.2)
0.2 to 10.0°C
ALARM-1 BAND
Sets symmetrical positive and negative deviation (offset) limits
from Temperature control setpoint for both High and Low Alarm-1
activation.
Example:
If Band = 0.5°C, then
High Alarm Limit = Se 0.5°C
Low Alarm Limit = Setpoint - 0.5°C
ALARM-1 HYSTERESIS
Sets differential (dead) band between ON and OFF states of
Alarm-1.
(Default : 25)
0 to 250 Seconds
(Default : 1.0)
0.5 to 25.0 Seconds
(in steps of 0.5 secs.)
CYCLE TIME
Sets the total ‘On + Off’ time in seconds for time proportional
power output for temperature control loop through Output-1.
DERIVATIVE TIME
Sets derivative time constant in seconds for temperature control
loop. Setting the value to 0, cuts-off the derivative action.
