KLTM-RFID

KLT-SS-RFID

The KLTM-RFID and KLT-SS-RFID Safety Interlock switches are designed to fit to the leading edge of machine guard doors to provide robust
guard locking and provide a double tamper resistant interlock mechanism.
They are designed to provide robust position interlock detection for moving guards and will remain locked until the solenoid voltage is applied
to the switch. They can be used in conjunction with delay timers to provide the solenoid energise signal only after a pre-determined the time
has run down.

Operation:

The switch is rigidly mounted to the fixed 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 mechanical tongue actuator profile is designed to match a cam mechanism within the switch head
and provides a not easily defeatable mechanical interlock. There is also an RFID coded actuator which aligns with a programmed receiver
inside the switch housing during closing of the guard. Only when both actuators are correctly aligned and the RFID coding is verified correctly
can the safety contacts close and allow the machine start circuit to be enabled. When the solenoid is energised the safety contacts are

Record any RFID codes as required by factory rules or with reference to any risk assessment for the particular application.
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.
The safety functions and mechanics must be tested regularly. For application where 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 Cat 3/4 or once per year for PLd Cat 3 (ISO13849-1). Where possible it is recommended that the control system of the machine
demands and monitors these tests, and stop or prevents the machine from starting if the test is not done.(see ISO14119). It is the responsibility of the user to ensure the correct overall
functionality of its systems and machines. IDEM, its subsidiaries and affiliates, are not in a position to guarantee all of the characteristics of a given system or product not designed by IDEM.

Installation:

1. Installation of all IDEM interlock switches must be in accordance with a risk assessment for the individual application.

If fitted, ensure access to at least one of the auxiliary release points. The switch can be positioned / shielded to prevent unintended actuation of the auxiliary release.
The release function is achieved by use of a tool and is to be used in exceptional circumstances. If used the release can be protected by use of a tamper coating to protect
against unintended operation. If operated this tamper protection must be restored.
Always fit the aperture plug to the unused entry aperture to prevent debris entering the switch mechanism.

4. The RFID code is factory set. For instances where replacement of the RFID actuator is required please contact IDEM via e-mail: [e-mail].

5. The switch is supplied with removable conductor links fitted 41/42 and 31/32. If required by the control circuit these may be removed to offer independent monitoring of the
solenoid locking function or the actuator position.

6. After installation check operation of all control circuits and the locking function.

Every month: Check correct operation of all circuits and the Lock function. If the actuator shows signs of bending or the
switch head housing displays mechanical damage then remove and replace. IDEM will not accept responsibility for
failure of the switch functions if the installation and maintenance requirements shown in this sheet are not implemented.
Every 6 months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture

Installation must only be carried out by competent personnel and in accordance with these instructions.

2. M5 (or appropriate) mounting bolts must be used to fix the switch and actuator mounting plates. The tightening torque to ensure reliable fixing is 4.0 Nm.
Tightening torque for the lid screws and cable glands must be 1.5 Nm to ensure the IP seal. The actuator entry position (Front or End) can be selected by using the internal
slide switch inside the switch cover (See Fig.1 on page 2). Do not mount adjacent switches or actuators closer than 100mm.

3. Always fit a mechanical stop to the guard to prevent damage to the front of the switch.
Always ensure correct alignment of actuator and handle with front apertures of the switch and guide. Use alignment guides to ensure that the actuator enters the switch
without interfering with the sides of the aperture.

For applications with a run down time after removing power, ensure that the correct timing allowance has been made before the solenoid is energised.

In the event that a Fault condition requires reset, follow the reset instructions:

1) Turn off all power to the switch and open the guard.

2) Remove the switch cover.

3) Using a 2mm terminal screwdriver hold down the RESET button inside the switch housing and turn on the switch
power (see Fig.2).

4) Release the RESET button, the yellow LED will flash, close the guard and the yellow LED will turn steady yellow.
(If yellow LED continues to flash check for mechanical fault (e.g. damaged actuator or switch head)).

5) Turn power off and then on, the green LED will illuminate.

6) Re-fit the switch cover.

7) Open and close the guard ensuring all safety functions are correct –refer to any risk assessment for the particular
guard application.
