Selection inputs
Only for "Multi"!
S1
S2
S3
The input signal (static) of +24 VDC relative to "Com" terminal must be
stable during 50 ms min. before "Teach" or "Start".
• "Teach mode"
S1, S2, S3 for function "Multi Learn":
3 selection inputs = 8 coded scanning positions
A maximum of eight positions can be binary coded via
the three selection inputs.
• "Switch mode"
S1 for dividing "Monitoring function":
S1=0: Object monitoring
S1=1: Free space monitoring
S2/S3 without features
Inputs which are not used, remain open.
Default: S1=0, S2=0, S3=0
Relay outputs
K.O.
These two terminals are used to indicate a fault message (K.O.).
O.K.
These two terminals are used to indicate a no fault message,
i.e. a good cycle (O.K.).
The terminals have been designed as dry relay contacts. By switch selection, they may be
configured as either normally open or normally closed.
The contacts have been designed for 250 VAC and, by additional internal circuits, protected
against inductive switch-off peaks of up to 19 W (2 ms).
Note:
Relay as normally closed contact: active = open
inactive = closed
Relay as normally open contact: active = closed
inactive = open
When there is no power to the unit, the contacts always will be open.
Even when using relay as normally closed, they are open (like the active status) when the
power supply is not connected.
