Do PLe applications need two interlocks?

Published:  17 December, 2014

Rob Lewis, MD of FORTRESS INTERLOCKS has taken a look at interlock redundancy. There is a lot of interest in whether redundancy is required when it comes to interlock actuators. For PLe applications careful consideration must be given to the actuator.

If a normal pressed actuator is to be used then, in all but the lightest duty applications, a secondary interlock should be used. Alternatively an interlock which incorporates an actuator and a separate non-contact sensor could be used. The Fortress amGard Pro interlock, on the other hand, having an actuator that is stronger than the rest of the guarding, could provide the simplest solution to achieving a PLe rating.
