Inputs at X9
Only use input X9.1 in exceptional cases. Please contact us for a detailed
description of how to use this input.
The internal power contactor can only be switched when this input is
closed (see ON contact).
Opening the OFF contact immediately switches the internal power
contactor off.
Note:
The power contactor has not been designed to switch always
under load, i. e. it is only appropriate for de-energization and
occasional E-stop. Use the "E-stop" function for emergency
switch-off (see DIAX03 Function Description for details).
When the ON contact is activated, the internal power contactor is
switched on, if
•
the OFF contact is closed and
•
a machine-internal ready state is being signaled (see Bb1 contact
also).
The internal power contactor is a self-holding contact.

If the internal main contactor K1 to increase safety is switched off directly,
in other words, not via the attached auxiliary relays, then the contactor coil
may also be directly isolated from the mains. This means that the bridge
between X10/L and X10/K must be removed and the contactor coil K
must be externally connected to L via a switch.
