PSEN op 2/4 Series
- Application with two optoelectronic sensors:

PSEN
d2
d : Distance required for the muting activation to be accepted; the
2
approach speed of the package is the key factor for this
distance:
d [cm]= v[m/s] * 0.5[s] * 100
2max.
d Should be arranged so that both the muting sensors cross
2min.
within the monitored area.
•
In each case, the muting sensors must be positioned so that a
muting function cannot be activated as the result of an operator
unintentionally passing by.
• Muting can be activated in 2 ways:
- Activation of both muting inputs simultaneously
- Activation of Muting 1 first and then Muting 2, or vice-versa.
•
Both activations should occur in a precise time sequence, in which
no more than 0.5 s is allowed to elapse between the first and
second activation, otherwise muting will not be activated.
•
Muting cannot be activated when the ESPE is in "BREAK" mode
(red LED is lit, protected field is interrupted).
•
The maximum muting period is restricted to 10 minutes. Even if the
muting sensors are still activated when this time has elapsed, the
muting function will be cancelled and the safety device will return to
its normal operating status. The muting function can only be
reactivated by repeating the muting activation process described
above.
