SG BODY REFLECTOR MUTING

(*) This is true for light curtains configured as T Muting. For light curtains configured as L Muting, override will terminate when muting
sensors are de-actuated AND t
he light curtain’s beams are free.
•
Keep the button pressed until the clearance of the protected area has been completed.
•
The maximum length of the Override function is 120 sec. After that time, the ESPE returns
to NORMAL OPERATION, even if the OVERRIDE button is pressed. Obviously, if the
button is released within the 120 seconds, the Override function stops immediately.
•
When override is de-actuated, the light curtain will return into the NORMAL OPERATION.
All possible fault conditions at runtime are shown below.
Fault Cause Action
Contacts out-of-sync: when
trying to actuate the override
function, the activation timer
expires.
A shortcut to VDC or GND may be present on
one of the override input lines or a contact may
be defective.
Override is not actuated: the fault is signalled by
the user interface (see Figure 43)
This is not a lockout condition: the override can
be run after fixing the fault.
