FAIL/Memory End Wiring (/F1, Option)
WARNING
• To prevent electric shock, ensure the main power supply is turned OFF.
• If a voltage of more than 30 VAC or 60 VDC is to be applied to the FAIL/Memory
End output terminal, use ring-tongue crimp-on lugs with insulation sleeves on all
terminals to prevent the wires from slipping out when the screws become loose.
Furthermore, use double-insulated wires (dielectric strength of 2300 VAC or
more) for the signal wires on which a voltage of more than 30 VAC or 60 VDC is
to be applied. For all other wires, use basic insulated wires (dielectric strength
of 1350 VAC). To prevent electric shock, attach the terminal cover after wiring
and make sure not to touch the terminals.
Wiring Procedure
1.
Turn OFF the recorder and remove the cover for the option terminal.
2.
Connect the FAIL/Memory End output wires to the terminal.
The terminal arrangement for the FAIL/Memory End output option is as follows.
Terminal position
Option terminal
Terminal arrangement (only the position of the FAIL/Memory end output
terminals is indicated.)
When the relay is not energized, NC is closed and NO is open. C is the common
terminal.
3.
Replace the terminal cover and fasten it with screws.
Note
•
The option terminal block itself can be removed by loosening the two screws at the top left
and bottom right of the terminal block. This makes wiring work easier. To prevent bad
contacts, make sure to securely tighten the screws after wiring.
•
FAIL output is a de-energize relay, and the Memory End output is an energize relay.
