IDEM Safety Limit Switches - Operation, Installation and Maintenance

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 correct mounting bolts (M4 or M5 depending on the switch model) and ensure 2Nm tightening torque for secure fitting.6. Ensure 1Nm tightening torque for conduit plugs and cable glands to achieve IP rating.7. The safety functions and mechanics must be tested regularly. For applications where infrequent guard access is foreseeable, the

system must have a manual function test to detect a possible accumulation of faults. Do this at least once per month for PLe Cat3/4 or once per year for PLd Cat3 (ISO13849-1). Where possible, it is recommended that the control system of the machine demands and monitors these tests, and stops or prevents the machine from starting if the test is not done. (See ISO14119).

Maintenance:Every Month: Check switch actuator and body for signs of mechanical damage and wear. Replace any switch showing damage.Every 6 Months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture ingress. Never attempt to repair any switch.

Note: These guidelines apply to all IDEM Safety Limit Switches

Operation:Operation of the switches is achieved when a moving object causes 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 mounting of limit switches is critical to obtain optimum performance and ensure safety reliability.Installation of all switches must be in accordance with a risk 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 shock.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.
