Installation and Wiring
General Considerations
The 440G-LZ guard locking switch is designed for use on guards that are
engineered to be rigid without sag. A separately mounted latch (e.g.
magnetic or mechanical) and mechanical stop are required.
It can be used on Full Body Access guards that do not require escape
release, emergency release or remote release guards, and in any situation
where the alignment tolerance falls within the stated specification.
Installation must be in accordance with the present manual and must be
carried out by qualified personnel exclusively. The 440G-LZ guard locking
switch is intended to be part of the safety-related control system of a
machine. Before installation, a thorough risk assessment must be
performed to determine whether the specifications of this device are
suitable for all foreseeable operational and environmental characteristics
of the application.
Refer to the Specifications section of this manual. Use appropriate screws,
bolts, or nuts fitted by tools to mount the switch and actuators to avoid
tampering.
Do not over-torque the mounting hardware.
Pair Proximity
During installation, make sure you observe the following restriction: you
must maintain a minimum distance between each pair of switches you
mount. Make sure to maintain a minimum distance of 120 mm (4.72 in.)
between any two switches and actuators, as indicated in the following
illustrations.
ATTENTION:
F
or the switch, actuator and actuator mounting bracket:
• Only use the designated mounting holes.
• Never drill or use to support other structures such as a conduit, cable
ways, or other hardware.
