Functions
4. If a beam channel is blocked that is not set during the muting function, the
muting function will be deactivated and the control output (OSSD 1, OSSD 2)
is turned off.
5. The factory setting for the input operation is NONO (Normally Open,
Normally Open). You can set the input operation to NONC (Normally Open,
Normally Closed). Connect a sensor or switch with an output operation of NO
(Normally Open) to muting input 1 and a sensor or switch with an output
operation of NC (Normally Closed) to muting input 2. To activate the muting
function, the time between the muting input 1 turning ON from OFF (= open
state) and the muting input 2 turning OFF (= open state) from ON must be no
longer than 3 seconds. The output operation for NONC works as follows:
NO (Normally Open) type:
• ON when no light is
received (photoelectric
sensor, etc.)
• ON when object is
approaching (inductive
proximity sensor, etc.)
• ON when object has
contact (position switch,
etc.)
NC (Normally Closed) type:
• ON when light is received
(photoelectric sensor,
etc.)
• ON when no object is
approaching (inductive
proximity sensor, etc.)
• ON when no object has
contact (position switch,
etc.)
6. If the muting lamp diagnosis function is inactive, the muting function is
maintained even if a lamp blows or a lamp is not connected.
