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.

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.

• Only use the designated mounting holes.

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

a fault condition.

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.
