7.5 Timer
Timer signal
A timer signal (tF1) is provided which can be transmitted via binary
outputs or used for internal links, e. g. to switch off the controller
(output value 0%) or to toggle the set point values.
Ö Chapter 7.6 „Outputs“ and Chapter 7.7 „Binary functions“
The timer signal is active either when the timer runs or during the timer
follow-up time (see below). The signal can be inverted via the „SiGn“
parameter.
Timer time
The timer runs for the set time t1.
Timer time, current timer running time and residual timer time can be
displayed in the operator or user level (the timer time can also be
changed here).
Starting the timer
The start behavior can be set and triggered via power ON, function key
or binary signal. Subsequently, the timer time t1 is counted to zero
either immediately or after the process value has reached a
programmable tolerance limit. The timer can be stopped (waiting time)
or cancelled.
How can I see that the timer is running?
The green timer LED above the clock symbol flashes while the timer
time counts down, and, if a timer value is displayed on the green
display, its middle decimal place (xx.xx) flashes.
Timer follow-up time
When the timer follow-up time t2 is activated, it starts after the timer
has elapsed. The timer follow-up time can be used, e. g. to control a
horn.
