Application:
The UGB-KLT Gate Box (incorporating an RFID interlock switch) is 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 position interlock detection for moving guards and will keep the guard locked until a voltage is applied to the switch
solenoid. They will hold guards closed up to 4000N .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.
The UGB-KLT housings incorporate standard 22mm pushbuttons, switches or lamps to facilitate machine request functions and diagnostics all in one housing.
Operation:
The UGB-KLT 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 positively operated 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 in place 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 positively
opened and the machine control circuit is broken. Optional features are Sliding Handles, Rotary Handles and Rear Escape function

Operating Instructions
Important:
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).
Installation:
1.
Installation of all IDEM 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 mounting. 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). Always fit the aperture plug to the unused entry aperture to prevent debris entering the switch mechanism.
3.
If installing the UGB-KLT without using a Sliding or Rotary Handle then 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.
If fitted, the Manual override function is achieved by use of a tool and is to be used in exceptional circumstances.
The release can be protected by use of a tamper coating to protect against unintended operation. If operated this tamper protection must be restored.
4.
If fitting Sliding or Rotary Handles, ensure that M6 mounting bolts are used to fix the appropriate mounting plates. The tightening torque to ensure reliable fixing is 4.0 Nm.
5.
The Front and Rear Rotary Handles can be adjusted for desired position by loosening the locking bolt which fixes the handle to the switch body.
6.
The RFID code is factory set. For instances where replacement of the RFID actuator is required please contact IDEM via e-mail:
7.
The Interlock 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.
8.
Always check the electrical ratings of any 22mm devices fitted. Never exceed these ratings.
9.
After installation check operation of all control circuits, the locking function and rear escape functions.
For applications with a run down time after removing power, ensure that the correct timing allowance has been made before the solenoid is energised.
Maintenance:
Every month: Check correct operation of all circuits and the Lock function. If any part of the UGB-KLT 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 ingress. Re-check Installation conditions above.
Never attempt to repair any switch.
