Matched Relays Mean Optimum Control
Regardless of what type of point-of-operation, or perimeter guarding system you’re using, the potential for electrical/mechanical failure is always present. That’s why many designers equip their systems with safety controllers. These devices detect faults that can compromise safety-system operation, insuring system reliability. Example: weld/stuck contacts, open/short circuits, open/misaligned guards, insufficient operating voltage & system component failures are just some of the detectable faults. SCHMERSAL also offers devices that help pinpoint fault location with defined flashing LED patterns to minimize equipment downtime.
In addition to sensing the actuation of an E-stop, machine guard interlock, light curtain/beam or pressure mat; modules (depending ono your model) can detect the following types of potential safety circuit faults:
- Welded interlock or E-stop switch contact
- Misaligned guard
- Open circuits and short circuits
- Faults in the module's monitoring circuits
- Welded/stuck contacts in the controlled output motor contactor/control relay
- Inadequate supply voltage to module
- Capacitive/inductive interference or module's inputs
