Safety Limit Switches
4. Always ensure that when running electrical conductors that they are routed correctly and no damage can occur to the cable insulation.
5. Always use M5 mounting bolts and ensure 2Nm tightening torque for robust fitting.
Maintenance:
Every Wee : Chec switch actuator and body for signs of mechanical damage and wear. Replace any switch showing damage.
Every 6 Months: Isolate power and remove cover. Chec screw terminal tightness and chec for signs of moisture ingress. Never attempt to repair any switch.

APPLICATION:
IDEM Limit switches are designed to be mounted for position sensing of moving applications e.g. guard doors, conveyors, machine beds, elevators etc.
They are available with linear plungers, rotary levers or roller plungers and either slow or snap action contacts. All contact bloc s are positively operated to satisfy IEC 60947-5-1.
Operation:
Operation of the switches is achieved by a sliding actuation of the moving object to cause deflection of the switch plungers or levers.
For Safety applications it is important that the moving object does not pass completely over the switch actuators so as to cause the actuator to return to its original position.
Installation Guide: Correct Mountin of Limit Switches is critical to obtain optimum performance and ensure safety reliability.
Installation of all switches must be in accordance with a ris assessment for the individual application.
Installation must only be carried out by competent personnel and in accordance with these instructions.
1. Never use the switch as a mechanical stop. Ensure that the actuator is protected from mechanical shoc .
2. For switches with Linear actuators the actuating direction and force from the moving object should be applied in line with the axis of the plunger.
3. For switches with Rotary actuators or rollers the operating cam from the moving object should be designed such that the switch is never operated beyond its over travel position.
Always use a 30 degree tapered actuating cam.
