Idem LSPS-R Series Operating Instructions

Application:
IDEM LSPS-R Limit Switches with Reset Button 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 blocks 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 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 it's over travel position. Always use a
30 degree tapered actuating cam.
4. The heads of the switch can be rotated to obtain the best switch orientation by removing the 4 head screws and rotating the head through 90 degrees. Always ensure the 4 head screws are
tightened to 1Nm to ensure switch robustness.
Incorrect
5. Always ensure that when fitting electrical conductors that they are routed correctly and do not interfere with the switch cover during fitting.
Maximum conductor size is 1.5 sq.mm, contact terminal tightening torque is 1Nm.
6. Tightening torque for the lid screw is and cable glands is1Nm to maintain IP rating.
7. Always use M4 mounting bolts and ensure 2Nm tightening torque for robust fitting.
8. The switches are reset by pulling out the blue pin after switch actuation.
9. The safety functions and mechanics must be tested regularly. For applications were infrequent guard access is foreseeable, the system must have a manual function test to detect a
possible accumulation of faults. 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 Week: Check the 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.
