Summary of Changes

Added required minimum distance between switches and detail for 5­pin quick-disconnect models.

Figure 1 - Assembly Overview

440G-LZ Guard Locking Safety Switch

For proper installation, a
minimum of two fasteners
must be used, at least one of
which must be fitted to the top
row of holes, closest to the
bend in the actuator mounting
bracket.

2 x M5/M6 CSK

3 x M5

The locking bolt must always enter
the actuator mounting bracket first.

This 440G-LZ Guard Locking switch is for use on guards that are
engineered to be rigid without sag. A separately mounted latch (for
example, magnetic, mechanical) and mechanical stop is required.

Installation must be in accordance with these instructions and must be
carried out by qualified personnel.

ATT EN TI ON : After installation, ensu re that there is no p ossibility
of lifting the ac tuator over the extended locki ng bolt. Adherence to
the recommended maintenance instructions forms part of the
warr anty.

This device is intended to be part of the safety-related control system of
a machine. Before installation, a risk assessment must be performed to
determine whether the specifications of this de vice are suitable for all
foresee able ope rational and environmental characteristi cs of the
application. See Specifications on page 5
and ratings.

Use appropriate screws, bolts, or nuts that are fitted by tools to mount
the switch and actuators to avoid the risk of tampering. Do not over
torque the mounting hardware.

Figure 4 - Orientation of Assembled S

Minimum Distance Between Switches

If a pair of 440G-LZ switches is mounted close to each other, the two
inductive fields interact causing crosstalk, which results in nuisance
faults and false operation.

An absolute minimum of 200 mm (8 in.) must be used to help achieve
correct operation.

The restriction applies if a 440G-LZ switch is mounted close to the
TLS-Z guard locking and the 440N-Z SensaGuard™ switches.

witch

ATT EN TI ON : For the switch, actuator and actuator mounting

bracket:

• Only use the designated mounting holes.

• Never drill or use to support other structures such as conduit,
cable wa ys, or other hardware.

IMPORTANT It might be easier to achieve actuator alignment by first

mounting just the actuator mounting bracket to the guard/
door and then fit the actuator to its mounting bracket.

It is not possible to mechanically extend the locking bolt
during installation, this can only be done electrically (see
Commissioning in the user manual).

ATT EN TIO N: After installation, be sure that there is no possibility
of lifting the actuator over the extended locking bolt.

After installation, be sure that there is no possibility of collision
when the actuator approaches the switch body.
