Power LED Lights on : Power for input and controlling GW is supplied.
Blinks : Under short circuit protection ( abnormal status ).
As the short circuit protective function is operating, the power
is not supplied.
To cancel blinking, turn off and return the power to GW unit.
Lights off : Power for input and controlling GW is not supplied.

Wiring
Branch wiring
For wiring method, refer to subsection "Wiring" ( page 15 ) of section "EX500" in this
manual. To input devices such as sensor, the power is supplied through the branch
wiring ( branch cable with M12 connector ). Therefore, there is no need to supply the
power to them individually.

Note : Internal wiring of M12 input block and key position for mounting sensor connector
No. 2 pins of M12 input block connectors are
wired to each other’s sensor signal input pins
( No. 4 pins ) internally.
This wiring enables direct input of signals from
two points combined into one cable through
concentric connector etc.
When connecting sensors, confirm the
specification of output signal carefully.
Otherwise malfunction can result.
The key position for mounting sensor
connector is as shown to the right. Consider
this key position when selecting sensor.
NOTE
Mount a waterproof cap on each unused connector of Input unit. The proper use of
waterproof cap can achieve IP65 Enclosure. The waterproof caps are delivered
together with each input block as accessories.
