Installation Instructions for the
GKN Series Multi-Entry Key Operated Safety Interlock Switch
WARNING
IMPROPER INSTALLATION
- Consult with local safety agencies and their requirements when designing a machine-control link, interface, and all control elements that affect safety.
- Strictly adhere to all installation instructions. Failure to comply with these instructions could result in death or serious injury.
MOUNT, WIRE, SEAL, AND TEST SWITCH
WARNING
IMPROPER OPERATION
- Ensure key travels to the given minimum insertion distance to ensure switch contact transfer.
- Ensure key travels to maximum extraction distance to ensure the correct operation of the positive brake mechanism.
- Do not exceed 50 N [11.2 lb] actuation force.
- Do not use the key as a stop for the door.
Failure to comply with these instructions could result in death or serious injury.
- Refer to:
- Page 6 for specifications.
- Page 7 for switch mounting.
2. Ensure proper clearance for the switch and key at the mounting location.
3. Align the switch and key together before mounting.
4. Mount switch and key:
- Torque switch to the mounting surface: 1,0 N m-1,4 N m [9 in lb-12 in lb] using M5 screws
- Torque key to the mounting surface: 1,0 N m-1,4 N m [9 in lb-12 in lb] using M4 or M5 screws
- Care should be taken to ensure that all mounted hardware cannot become detached during the operational lifetime in the intended application
5. Refer to the circuit diagram on switch housing. Diagram depicts a safety switch when the key is inserted.
6. Remove screws on the cover plate.
7. The three conduit openings have been molded using knockout. Break out the
conduit opening required for use.
8. Connect stranded wire (0,75 mm 2 to 2,5 mm 2, 18 AWG- 14 AWG) or solid
wire (0,75 mm 2 – 1,5 mm 2 , 18 AWG16 AWG) to connector terminals (Use copper
wire only, minimum 75 °C rated):
- Torque switch terminal screws: 0,8 Nm to 1,0 N m [7 in lb-9 in lb] M3
- Torque connector to secure the cable to switch enclosure (if required): 1,8 Nm to 2,2 N m [16 in lb-19 in lb]
9. Seal conduit opening according to instructions in PK 80112.
10. Reassemble cover plate with cover screw. Torque to
0,40 Nm to 0,50 Nm [3.5 in-lb to 4.5 in-lb].
11. Perform functional tests:
- Open and close protective guard several times to confirm key slides easily into switch head
- Open and close protective guard several times to confirm switch contacts transfer (change state) in each state
- Confirm the normally closed contacts open when the protective guard is open
- Confirm hazardous motion does not start when the protective guard is open
