5.6 Controlling the Output On/Off
This section explains the method used to control the on/off of the output by
connecting an external contact.
Possible electric shock.
•
The insulation of the external contact (S) and the connected cable
should be greater than the isolation voltage of the PAT. For the
isolation voltage of each model, see Chapter 9, “Specifications.”
• When using shielded wires for the connection, protect the uncovered
section of the shielded wire by using insulation tubes with a
withstand voltage greater than the isolation voltage of the PAT.
To minimize the influence of noise on the output, use a two-core shielded wire or a
twisted-pair wire to connect the control terminals and the external contact. Make the
wires as short as possible. Susceptibility to the effects of noise increases as the wires
get longer. When wires are long, proper operation may be hindered even if a cable
with anti-noise measures is used.
When using a shielded cable, connect the shield to the - (neg.) output terminal.

To control the output on/off using external contact, select the external control logic
setting of output on/off in the CONFIG settings from the following two modes.
• Turn the output on with a high signal (default) (CF22: H)
The output turns on when pin 14 of the J1 connector is set high (TTL level) or
opened.
• Turn the output on with a low signal (CF22: L)
The output turns on when pin 14 of the J1 connector is set low (TTL level).
If the output is set to off using an external contact, the OUTPUT switch on the front
panel is invalid. If you are not controlling the output using an external contact, turn
the output on by setting the external control logic setting of output on/off in the
CONFIG settings to high (CF22: H).
