Typical Wiring Diagram
Multiple Switch Wiring Diagram
GuardSwitches ™ are shown with the actuators in position—guard is closed. One 300-BT Series GuardSwitch ™ is required for each safety gate. Up to 50 switches can be used with
INT-03. When using the BLT switch models, the voltage drop (30 ohms) must be taken into consideration.

Multiple DPST GuardSwitches – Shown with actuators in position, all guards closed.
The L.E.D of the BLT model will be on when the guard is open. If multiple guards
are open, L.E.D will be dimmer. The maximum number of GuardSwitches that can
be used is 50, although troubleshooting and line resistance must be considered.
(Do not exceed 30 Ohms of combined contact and line resistance. Each GuardSwitch
will have less than 0.5 Ohms of resistance.)
