[External signal output function]
An ON signal is output when one or more units are in operation, and an Error signal is output when one or more units are
in error.

Use relays Z1 and Z2 that meet the following
specifications.
Operation coil
Rated voltage: 12 or 24 VDC
Power consumption: Max. 0.9 W
Important
●
Be sure to use an external power supply (12 or 24 VDC)
to avoid malfunctions.
●
Connect the external power supply in the correct
polarity to avoid malfunctions.
●
Do not connect the external power supply without
relays being connected to the controller (no load).
Note
●
The relays, lamps, external power supply, diodes, and extension cables are not supplied.
●
The total length of the lead wire and extension cable should not exceed 10 m (32 ft). (Use an extension cable of 0.3 mm
2
or
thicker.)
●
Each element will turn on during operation and when an error occurs.

Select an external power supply suitable for the relays used. (12 or
24 VDC)
Connect the external power supply in the correct polarity to input
and output the signals.

Note
* When connecting the external input/output cables to connector CN5
on the controller, punch out the knockout hole.
