9.1.2 Tolerance band
Timer modes 1,2 and 6 are provided with a freely adjustable tolerance band. The tolerance band around the set-point
can be adjusted via parameter
b.ti in the Conf menu (x = SP.2 _ b.ti )
(r page 53)
9.1.3 Timer start
Various procedures for starting the timer are possible:
g
When using the digital input as a switch (di.Fn = 0 / 1) or when using the Func switch-over function, the
timer is re-started automatically after elapsing. Switch-over, e.g. opening, will cancel the timer function.
g
Using the Func function as a switch for starting the timer is not recommendable, because the timer would
be re-started immediately after elapsing.
9.1.4 Signal end
If one of the relays shall switch after timer elapse, parameter TimE = 1 and inverse action O.Act = 1 must be
selected for the relevant output OUT.1 … OUT.3 in the ConF menu (r page 57, 58). If direct action is selected,
the relevant output signals the active timer.
9.2 Determining the timer run-time
The timer run-time can be determined via parameter t.SP in the PArA menu. The timer run-time must be specified
in minutes with one digit behind the decimal point (0,1 minutes = 6 seconds).
Alternatively, the timer run-time can be determined directly at extended operating level (r chapter 9.3).
