10-1 Connecting Via Two Force-Guided Relays
OMRON model G7SA relays provides force-guided relay outputs for machine control. See Figure 10-1 for the
preferred connection method using two force-guided relays.

WARNING
This product is designed for use on a 24 VDC, negative ground (protective earth) electrical system only.
Never connect the F3SL system to a positive ground (protective earth) system. With a positive ground (pro-
tective earth) wiring scheme, certain simultaneous shorts of both safety outputs may not be detected and the
guarded machine may not stop resulting is severe operator injury.
Never use only a single safety output to control the machine. Should this single output fail, the machine may
not stop, resulting in severe operator injury. The machine must be connected using both safety outputs.

Note 1: In regards to MPCE1 and MPCE2, which perform final control of the machine, use safety relays equipped
with a force-guide function (e.g. OMRON model G7SA).
Note 2: If the MPCE monitor function is not used, short circuit the MPCE monitor line (pink) to 0V power supply.
Note 3: When the load is not connected to control outputs 1 and 2, this system will enter error state and not
operate properly. For testing during installation, connect the 10 KW resistor (included in documentation kit)
to the MPCE1 and MPCE2 position.
Note 4: When using this system in automatic start mode, short circuit the start line (gray) to 0V power supply.
Note 5: When wiring, be sure to connect the proper color cords. Note that colors of the power supply lines are
white for +24 VDC; brown for 0V,differing from those of ordinary sensors.
Note 6: Connect the attached surge-killer in parallel to MPCE1 and MPCE2.
