PLZ-4WL
Superimposing Constant Current Mode (CC Mode)
You can superimpose current on the CC mode panel/remote settings by applying an external
voltage of -10 V to 10 V to the PLZ-4WL.
When the panel and remote control current setting is 0 A, an external voltage of 0 V results in
an input current of 0 A, and an external voltage of 10 V results in an input current of 100 % of
the specified range.
When the panel and remote control current setting is greater than 0 A and a positive external
voltage is applied, an input current proportional to the applied voltage is added to the input
current setting. On the other hand, if a negative external voltage is applied, an input current
proportional to the applied voltage is subtracted from the input current setting. Regardless of
whether the external voltage is positive or negative, the range of the input current is from 0 A
to 100 % of the specified range.
The precision of the PLZ-4WL cannot be guaranteed for voltages below -10 V or above 10 V.
Connected pins: J1-3 (signal), J1-4 (common)
To avoid noise interference, use a highly stable, low-noise external voltage source and
twisted signal wires.
1
Turn the POWER switch off.
2
Connect the external voltage across pins 3 and 4 of the J1 connector.
3
Turn the POWER switch on, and make sure that the load is off.
4
Set the operation mode and the current range.
If you also want to control the current range externally, be sure to set the range to H.
5
From the menu, select “2. Configuration” > “3. External” > “ADD CC” >
“ON.”
Doing so enables the modification of CC mode through external control.
6
Turn the power switch off and then on again.
The menu settings are applied.
CAUTION
To avoid damaging the PLZ-4WL, observe the following precautions.
• The maximum voltage that can be applied across pins 3 and 4 of the J1 connector is ±11 V.
Do not apply a voltage that exceeds this value.
• Pin 4 of the J1 connector is connected the negative load input terminal. Make sure that the
wire of pin 4 does not touch any of the other pins.
