Specification Wiring Specifications for Input unit Branch wiring For wiring method, refer to subsection "Wiring" ( page 9 ) of section "EX500" in this Item Specification manual. To input devices such as sensor, the power is supplied through the branch Connected block wiring ( branch cable with M12 connector ).
Option Wiring (continued ) Correspondence between input number and input block Cable with Remote I/O communication connector For details, refer to subsection "Wiring" ( page 9 ) in section "EX500" in this manual. Up to 8 Input blocks can be connected ( 16 points ). Input numbers are 0 - 15 from Input unit side.
Troubleshooting Option (continued ) Overall system Waterproof cap Mounted on unused ports of GW unit, input block, power block and output block. Item Solution/Corrective action The proper use of this waterproof cap can achieve IP65 Enclosure. ( The waterproof caps Solenoid valve Check the power for solenoid valves/output ( DC24V are delivered together with each input block as accessories.
Troubleshooting (continued ) Remote I/O compatible communication Item Solution/Corrective action RUN LED is not lit. Check the power for input and control ( DC24V ) is supplied. COM LED is not lit. Check the signal line from PLC is ERR LED is lit. connected correctly.
