Commissioning
The 440G-LZ 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 need to 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.
Set-up
During commissioning, connect the switch as shown in Figure 10:
• Connect brown wire (PWR) to 24V DC.
• Connect blue wire (GND) to 0V DC.
• Connect red wire (Safety A+) and yellow wire (Safety B+) to 24V DC.
• Connect green wire (Lock Command) to 24V DC.
• Safety A (gray) and Safety B (pink) — optional, no connection required
during commissioning
• Aux (white) — optional, no connection required during commissioning
IMPORTANT When the switch learns a new actuator, it no longer recognizes previously
learned actuators.
