IDEM SAFETY SWITCHES KLM-P2L User manual

Safety Interlock Switch with Guard Locking
Insta
llation:
1. Installation of all interlock 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.
2. M5 mounting bolts must be used to fix the switch and actuator, the tightening tor ue to ensure reliable fixing is 4.0 Nm.
To prevent loosening of the switch after installation, always fix the M5 ounting bolts with a thread-locking
co pound or secure using self locking nuts.
Tightening tor ue for the lid screws, conduit entry plugs and cable glands must be 1.5 Nm to ensure IP seal.
Only use the correct size gland for the conduit entry and cable outside diameter.
Tightening tor ue for the connection terminal screws is 0.7 Nm, max conductor size is 1.0 s .mm.
The switch head position can be selected by removing the actuator, loosening the 4 head bolts and then rota
ting
the head to the position re uired. Re-tighten the head bolts and then check actuator insertion and withdrawal.
Tightening tor ue for the head bolts is 1.5Nm.
3. Always fit a mechanical stop to the guard to prevent damage to the front of the switch.
Set the actuator gap to 3mm when the guard is closed and against the stop. (See Fig. A.)
Use alignment guides to ensure that the actuator enters the switch without interfering with the sides of the switch aperture.
Always fit the aperture plug to the unused entry aperture to prevent debris entering the switch mechanism.
4. After installation check operation of all control circuits and the locking function.
For applications with a run down time after removing power, ensure that the correct timing allowance has elapsed before energising the solenoid.
LED 1 GREEN will illuminate when power is applied to A1 and A2 (solenoid feed).
Hinged Guard Sliding Guard
Application and Operation:
The switch is rigidly mounted to the frame of the guard or machine. The actuator is fitted to the moving part (frame) of the guard and is aligned to the switch entry aperture. The actuator profile is
designed to match a cam mechanism within the switch head and provides a positively operated not easily defeatable interlock switch. When the actuator is inserted into the switch the safety
contacts will close only when power is applied to the solenoid. This will then allow the machine start circuit to be enabled. When the solenoid power is removed the safety contacts are opened
and the machine circuit is broken.
IMPORTANT: Any hazardous motion has to be controlled and a safe condition initiated in the event of power failure.
P2L versions (power to lock) may not be suitable for machines with a running down ti e.

IMPORTANT
The Risk Assessment for the particular application should include the risk of spare actuators. Spare actuators should not be readily available and must be securely controlled.
Application consideration must be given to the fixing of the actuator which has to be in a way that prevents disassembly by easy means.
Ensure that the switch holding force (Fzh) is sufficient to withstand the static forces applied during normal use and dynamic effects caused by bouncing of the guard shall not create an impact reaction
force which exceeds the holding force. If the expected impact reaction forces are higher than the specified holding force for the switch, then design measures must be applied to avoid the force.
The safety functions and mechanics must be tested regularly. For applications were infre uent 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 Month: Check the switch actuator and body for signs of mechanical damage and wear. Replace any switch showing damage.
Every 6 Months: Check for mechanical damage to switch body or actuator. Isolate power and remove cover.
Check screw terminal tightness and check for signs of moisture ingress.
Never attempt to repair any switch. Replace any switch displaying damage.
These require ents for part of the product warranty.
