Sensing and Control
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 AND SEAL SWITCH
IMPROPER OPERATION
•
Ensure switch actuator achieves sufficient travel
for positive opening of normally closed (NC)
contacts to occur.
•
Do not use the device as a stop for the door.
Failure to comply with these instructions could
result in death or serious injury.
APPLIED POWER
•
During installation and functional testing, ensure
power is not applied to the machine.
Failure to comply with these instructions could
result in death or serious injury.
1.
Refer to:
•
Pages 2 and 3 for EN 50047 wiring
configurations, specific travel distances for
each switch code (Ag=silver contacts,
Au=gold-plated contacts) and switch mounting
dimensions.
•
Page 4 for specifications.
2. Rotate switch head to desired position (90°
increments). Use the TORX

tamper-resistant
bit (included). Torque screws to 0,5 N m
(4.4 in lb).
3. Mount switch:
•
Ensure the operating lever pivot point and the
protective guard pivot points are as close to
each other as possible. Ensure the pin (not
included) fastened to the protective guard that
actuates the lever cannot become
disconnected from the lever.
•
Mount switch with lever using two M5 or #10
tamper-proof screws (not included). Torque
screws to mounting surface to
4,9 N m - 5,9 N m (43 in lb - 52 in lb).
4. Refer to circuit diagram on switch housing.
Diagram depicts safety switch in the “free
position” (protective guard closed). NC contacts
must be used for the safety circuit(s).
5. Remove tamper-proof screws on cover plate.
6. Connect stranded wire (0,75 mm
2
- 2,5 mm
2
,
18 AWG - 14 AWG) or solid wire (0,75 mm
2
-
1,5 mm
2
, 18 AWG - 16 AWG) to connector
terminals (use 90
°
C wire when ambient
temperature is over 75
°
C.):
•
Torque switch terminal screws to
0,8 N m - 1,0 N m (7 in lb - 9 in lb).
•
Torque ground screw to 0,8 N m - 1,0 N m
(7 in lb - 9 in lb) (GSC and GSE versions).
•
Torque connector to secure cable to switch
enclosure (if required) to 1,8 N m - 2,2 N m
(16 in lb - 19 in lb).
7. GSE version only: Plug unused conduit entry(s)
(plugs included). Seal conduit opening according
to instructions in PK 80112.
8. Perform functional tests:
•
Open and close the protective guard several
times to ensure proper travel of the operating
lever.
•
Open the protective guard to ensure that the
NC contacts open.
9. Reassemble cover plate. Torque cover screws
0,5 N m (4.4 in lb).
