1. Simply easy! TM XUSL2E/4E light curtains Pilot light ? How to provide a signal to a pilot light or to a PLC input

2. Telemecanique Sensors 2 - Technical support – April 17 th, 2015 XUSL2E/4E light curtains ●Alternative to supply a pilot light or a PLC signaling input ●No additional output integrated into the light curtain to provide such electrical signal ●External light or PLC input, how to energize it : ●Either by using directly the NC contact available in the FSD (final switch device) connected to the OSSD. ●Either by an external component, when a safety interface is used If it is associated to a safety relay, if possible use an optional output of this relay (or of the monitoring unit). Please check current compatibility of this output with the light or PLC input.
