Contact position if safety priority 2
Contact position if safety priority 3
The same programming options exist as those for parameter Contact position if safety priority 1.
Contact position when forced operation
and all safety priority x end
Options:
This parameter is only visible if the forced operation or a function Safety priority x (x = 1, 2 or 3) is activat-
ed.
The contact position of the relay at the end of the forced operation is defined here.
•
calculate present contact position: After forced operation has ended, the switch value is recalculated
and immediately initiated, i.e., the Energy Actuator output continues to operate normally in the back-
ground during forced operation, the output is not changed and only set after the end of safety priori-
ties.
•
unchanged: The contact position is retained during forced operation or safety priority. The contact po-
sition only changes when a new switch value is calculated.

Object "Forced operation" on
bus voltage recovery and ETS reset
This parameter is only visible if forced operation is activated.
Depending on whether the Forced operation communication object is a 1 bit or 2 bit communication
object, there are two different parameterization possibilities available:
With selection 1 bit object:
Options: inactive
active
•
inactive: Forced operation is switched off, and the output behaves in the same way as with pa-
rameter Behaviour at end of safety.
•
active: Forced operation is active again after bus voltage recovery or ETS reset. The switch
position of the output is determined by the parameterization of Contact position if forced opera-
tion.
With selection 2 bit object:
Options: 0 = inactive
2 = OFF
3 = ON
•
0 = inactive: Forced operation is switched off, and the output behaves in the same way as with
parameter Behaviour at end of safety.
•
2 = OFF: The communication object Forced Positioning is written with the value 2, and the out-
put is switched off.
•
3 = ON: The communication object Forced Positioning is written with the value 3, and the out-
put is switched on.
