Dwell Timer
A dwell timer is used to control a process at a fixed temperature for a defined period. At
the end of the time period the controller will switch off the output power to the
elements.
Press scroll
until the display shows TM.CFG <TIMER CONFIGURATION>. Using the up
down
select Dwell.
When Dwell parameter is selected, the Timer resolution (TM.RES), Time duration
(DWELL) and Timer Threshold (THRES) functions become available.
Press scroll
until the display shows TM.RES < Time resolution >. Use the up
down
to select the timer units in Min or Hours.
Press scroll
until the display shows DWELL < SET TIME DURATION >. Use the up
down
to enter the time duration required.
Press scroll
until the display shows THres < TIMER THRESHOLD >. Use the up
down
to select the temperature threshold that you require the timer to start at.
The threshold value is ±n around the setpoint (n=threshold value).
Example: If the setpoint is set to 800 °C and the timer threshold is set to 2, after the
timer is activated it will not start until the process value reaches 798 °C if ramping up or
802 °C if it is cooling.
Note: If the threshold is set to OFF, the timer will either; start to count down as soon
as it is activated with the mode keys or if a ramp rate has been set (see section 3.5.1
), the timer will start as soon as the ramp reaches the setpoint. (see section 3.7.1)
3.6.3
