Override - Datasensing SH4 STANDARD MUTING Product Reference Manual

OVERRIDE

Override functions allows to force safety function deactivation whenever it's necessary
to restart the machine despite one or more ESPE beams being intercepted. The aim is
clearing protected area of any working materials blocked ahead of ESPE because of (i.e.)
a cycle anomaly.
Supposing that a pallet is intercepting one or more beams, the conveyor belt can't be
restarted because of ESPE detecting intercepted beams. With Override activation nor-
mal operation is restored.
NOTE: For the SH4-X-XXXX-SM-8-5 models, two separate redundant
inputs (pin 3-OVR1 and pin 8-OVR2) have to be connected through one nor-
mally open contact to 24Vdc and one normally open contact to 0V thus to
provide complementary inputs (see "SH4-X-XXXX-SM-8-5 models" on
page 54).
NOTE: For the SH4-X-XXXX-SM-8 models, a single override input (pin 1) is
provided for compatibility with SG-N and SE models but a specific signal
pattern must be read at the input for override activation (see "SH4-X-
XXXX-SM-8 models" on page 57).
