OR logic operation; Value of logic object after bus voltage recovery: 0;
Relay: make contact
The relay can only be opened via the “Switch object” once a
“0” telegram has been received via the “Logic object”.
OR logic operation; Value of logic object after bus voltage recovery: 1;
Relay: make contact
L L
The logic object is preassigned the value “1” after a
RESET. The actuator will immediately switch on the
output in the “make contact” mode. The OR logic
function is only reset by a “0” telegram at the logic
object.

OR logic operation
While the “Logic object” has the value “0”, switching can be
carried out as usual via the address of the “Switch object”.
Any set delay periods are still valid. The closing of the relay
is carried out immediately via a “1” telegram to the “Logic
object” (object with higher priority). A delay is no longer
carried out. If the value of the “Logic object” is then set to
“0” again, the actuator immediately switches to the re-
quired state.
Example:
An opening lock-out or central ON function (e.g. lighting
for cleaning buildings) can be implemented with an OR
logic operation. If the value of the “Switch object” is also set
locally to “1”, the relay remains closed when the opening
lock-out is removed (value of the logic object changes from
“1” to “0”).
