„Step“ will be flashing alternately
(light and dark).

(e.g.

Core sensor break, program is terminated only when nominal values are pre-programmed.
8.4.1 Enabling signal relays
This setting allows you to determine the time interval during which a signal relay may be switched
on. If an interval time (greater than ZERO) has been entered, the controller can only switch on the
signal relay during this time interval. In addition you can pre-program whether you want to be asked
about enabling the signal at the start of every program.
Factory setting:
Signal enable: "Yes"
Time from: 00:00 to 00:00
(means: Signal can always be activated)
Signal can be programmed before the start of a program (Prg.sig.start): "No".
Be aware
▪
If you select "No" for "Signal enable" the controller
will
not activate
the signal.
▪
If you select "Yes" for „ Progam signal before program start “ (Prg.sig.start), you can
activate (LED in the button will light up) or de-activate (LED in the button be off) the
signal before the start of a program (standby mode) by pressing the button
for 3 sec.
