9.11 Integrated multifunction-time relay
The WTS-300 has an integrated time relay function by which external components
can be switched. There is no need of an additional time relay.
Setting as follows:
Select time relay function via parameter [A86] (selection 1..8).
Assign output function '22' to a free relay [A1..A20].
Determine the trigger signal:
- [A87] = 0:
Function '24' must be assigned to a free
digital input [A21..A33].
- [A87] = 1..x:
1..x: the trigger signal is provided by the corresponding
output function. '1..26' of the control - see [A1..A20]
Set the desired switching times in parameters T1 [A88] and T2 [A89].
Selection 1:
Delayed switch-on T1
When the trigger signal is given, a delay time T1 starts. After T1
has elapsed, the relay output is switched on (but only as long as
the trigger signal is present). If the trigger signal is shorter than T1,
the relay is not switched on.

Selection 2: Switch-off delay T2
When the trigger signal is given, the relay output is switched on at
the same time. If the trigger signal drops off, a time T2 starts. The
relay is only switched off after T2 has elapsed.

Selection 3:
Switch-on and switch-off delay T1 and T2
If the trigger signal is given, a delay time T1 starts. After T1 has
elapsed, the relay output is switched on (but only as long as the
trigger signal is present). If the trigger signal is shorter than T1, the
relay is not switched on.
If the trigger signal drops off, a time T2 starts. The relay is only
switched off after T2 has elapsed.

Selection 4: Switch-on pulse T2
If the trigger signal is given, a pulse of length T2 is given at the relay
output (but only as long as the trigger signal is present). If the trig-
ger signal drops off within the time T2, the relay also drops off, too.
