• Connect both ends of the shielded wire of the Dedicated
cable for CC-Link to ground (class D grounding) via SLD
and FG of each module.
• Securely connect the FG terminal of the module to ground.
• Securely ground the piping when running cables in piping.
Corrective Action
Wire an external power supply to the high-speed counter
module.
When using the external output (EQU1 to EQU2) terminals,
wire an 10.2VDC to 30VDC external power supply as it is
needed.
Even when not using external output terminals (EQU1 to
EQU2), wire the 12/24V terminal (pin number: 26) and the
COM terminal (pin number: 27) to an external power supply.
(Refer to Section 4.6.5)
The coincidence output function signal is not output.
(Fuse for external power supply which operates the internal
photocoupler when the EQU terminals are used)
The fuse cannot be changed by the user. Please consult your
local Mitsubishi representative.
