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 27).


Signal end
If one of the relays activates after the timer has elapsed, 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 32). If direct action is selected, the relevant output signals the active
timer.
9.5.2 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 9.5.3).
