Commission the Safety Switch
The 440G-MZ safety switch is available with standard coded actuators or
unique coded actuators.
• Switches with standard coded actuators are ready for use and do not
require commissioning.
• Switches with unique coded actuators must be commissioned before
use. The actuator teach process is not performed at the factory and
must be performed when the switch is first put into use. After the first-
time learn, this process can be repeated up to seven more times with
unique coded replacement actuators.
Setup
The 440G-MZ safety switch can be set up in OSSD mode or GuardLink® mode.
During commissioning, connect the switch as shown in Figure 11
.

IMPORTANT When the switch learns a new actuator, it no longer recognizes previously
learned actuators.
IMPORTANT If the 440G-MZ safety switch is connected in a GuardLink system, verify that the
GuardLink is powered ON and the switch is unlocked to insert the actuator and
initiate the teach process.
