Additional information for escape release and manual release cover versions with separate or fitted key.
Escape release version of TLS-Z power to release —
440G-TZS21UERH
Intended to allow
access through the
guarding (escape) and
not an emergency stop
device.
Meets ISO 14119:2013
Clause 5.7.5.2.
Escape release push.
Mechanical life of 10,000
operations
Max speed of actuation
160 mm/s
Max force 50 N
Minimum distance to release 5 mm (0.2 in.)
When the escape release is operated with the switch in the locked condition and with power
applied the OSSD outputs will turn off and the switch will enter a non-recoverable fault
(4 Hz red flash) requiring a power cycle to reset.

access.
Meets ISO 14119:2013
Clause 5.7.5.3.
Ensure the switch is
mounted/protected so as
to prevent accidental
operation.
When the manual release is operated with the switch in the locked condition and with power
applied the OSSD outputs will turn off and the switch will enter a non-recoverable fault
(4 Hz red flash) requiring a power cycle to reset
Ensure the knob is fully rotated back to the locked position before resuming operation.
Fitted manual release cover and separate key —
440G-TZS21UARH
Intended to allow access through the guarding from the outside of the hazardous
area (exceptional situations) and not as an emergency stop device or for routine
manual access.
