Test input option

This fail-safe equipment is based upon a permanent self-checking principle which means that
its integrity does not rely upon the use of the test option. However, the test input may be used
to interface the equipment with the machine circuitry to check the correct operation of the Final
Switching Devices K1 and K2 when the equipment is not often triggered by frequent beam
occultations :
A test cycle can be triggered when closing an external NO test contact or when opening an
external NC test contact. The configuration of the type of external test contact (NO or NC
contact) is be done by setting a jumper located behind the emitter side cover. In order to
change the jumper setting, open the emitter by unscrewing the side covers and follow the
following indications :
