TLSZR/L-GD2 Guard Locking Switch
Installation must be in accordance with the following steps and stated
specifications and conducted by competent personnel. The unit is not
to be used as a mechanical stop. Guard stops and guides must be fitted.
Adherence to the recommended maintenance instructions forms part of
the warranty.
This device is intended to be part of the safety-related control system of
a machine. Perform a risk assessment before installation to determine
whether the specifications of this device are suitable for all operational
and environmental characteristics of the machine. See
Technical
Specifications
for certification information and ratings.
Use nonremovable screws, bolts, or nuts to mount the switch and
actuators. Do not over torque the mounting hardware.
For use with flexible actuator only, 440G-A27143.
TLS-Z guard locking switches are classified according to ISO 14119 as
Type 4 switching devices.The RFID targets are classified as having a
high level of coding.
Measures are to be taken to minimize the need to defeat and to manage
the use and availability of spare RFID targets.
Technical Specifications
The device can be used under normal service conditions. Maximum
altitude up to 2000 m (6561.66 ft).
Voltage drop 2V maximum
ATTENTION:
Guard locking switches that are activated by the
Power to Lock principle, 440G-TZS21UPLH, must only be used after
a risk assessment has shown that the use of a Power to Release
principle, 440G-TZS21UPRH, is inappropriate, since the guard can
be immediately opened after a loss of the power supply or upon
activation of the unlocking signal.
