4-16 Applied Operation PAD-L
4.4 CC mode by remote control
4.4.1 Output current control with external resistor
Connecting and setting procedure
1. Turn off the POWER switch.
2. As shown in Fig. 4-11, remove the shorting bar across the control
terminals 0 and 1.
3. Connect an external resistor (R3) across the control terminals 1 and 2 as
shown in Fig. 4-11.
WARNING
• Isolate the external resistor (R3) and the cable connected to it with
at least the isolation voltage of the unit. For details, see 2.6
"Grounding the output terminal."
• When using a shielded cable for the connection, protect the
uncovered part of the cable with an insulation tube of at least the
isolation voltage of the unit.
CAUTION
• If R3 is disconnected, excessive current may be applied to a load.
To assure a good connection, use crimped terminals.
• To use R3 which consists of a multiple number of fixed resistors
and a switch, and select one of them for control, use a short
circuit type or continuous type switch.

NOTE
• To reduce the effects of noise on output, use a 2-core shielded wire or a
twisted-pair wire to connect to terminals, making them as short as possible.
Longer wiring results in greater susceptibility to the effects of noise, and use of
cables with antinoise measures may not solve the problem, resulting in
improper operation.
When using a shielded wire, connect the shield to the + (pos.) output terminal.
• Approx. 1 mA of current always flows in R3. For R3, use a 1/2 W or larger
resistor with a good temperature coefficient and small aging effect such as
metal film or wire-wound type resistor.

4. Recheck that the connections.
WARNING
• After connections are complete, install the terminal cover.
