GKey – Safety Lock
Excerpts from the original instructions
General description
GKey safety lock incorporate an RFID interlock switch and is designed to fit to the leading edge of machine guard doors to provide robust
guard locking and double tamper resistant interlock mechanism. It is designed to provide position interlock detection for moving guards
and will keep the guard locked until a voltage is applied to the switch solenoid.
GKey safety lock will hold guards closed up to 3000 N. It can be used in conjunction with delay timers to provide the solenoid energize
signal only after a pre-determined time has run down. GKey housing can incorporate positions for mounting of standard 22 mm
pushbuttons, switches or lamps to facilitate machine request functions and diagnostics all in one housing. These pilot devices are ordered
separately.
Installation
Installation of all GKey safety locks must be in accordance with a risk assessment for the individual application.
Installation shall only be carried out by competent personnel and in accordance with these instructions.
Use 16-28 AWG copper conductors. Terminal torque 0.7 Nm.
Caution!
Make sure the Manual unlock function selector is in “Locked” position before putting the cover back on.
Mount the GKey rigidly to the fixed frame of the guard or machine. Fit the actuator to the moving part of the guard and align it to the
switch entry aperture.
1. 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.
Always fit the aperture plug to the unused entry aperture to prevent debris entering the switch mechanism.
2. Always fit a mechanical stop to the guard to prevent damage to the switch.
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.
Do not mount adjacent switches or actuators closer than 100 mm.
3. The manual unlock function is achieved by using a tool and is to be used in exceptional circumstances. The release can be protected by
use of a tamper coating to prevent unintended operation. If operated, this tamper protection is damaged and must be restored to
ensure protection.
4. When fitting a handle, ensure that M6 mounting bolts are used to fix the mounting plate. The tightening torque to ensure reliable fixing
is 4.0 Nm.
Warning!
When cutting the panel to allow the movement of the rear handle:
• Consider the opening when calculating the safety distance
• Make sure that there are no remaining sharp cutting edges
Check after installation
After installation operation of all control circuits, the locking function and rear escape release functions shall be checked.
For applications with a run-down time after removing power, ensure that the correct timing allowance has been made before the solenoid
is energized.

Maintenance
Every month: Check correct operation of all circuits and the Lock function. If any part of the GKey product displays mechanical damage,
then remove and replace.
Every six months: Isolate power and remove cover. Check screw terminal tightness and check for signs of moisture ingress. Re-check
according to the installation instructions in this manual.
