4、 Installation and wiring：

1Dimensions: (Length)*wide*Deep)160*80*130

Installation panel opening size:152*76

2、The wiring terminal is shown in the diagram：

3Connect to four typical control circuits using wiring diagrams (for reference only)

Instructions:1.ZK-3CNo phase sequence requirement for wiring;

2.When placing an order, please specify the form of the control circuit.

5、 Usage of instruments：

1TheZK-3CThe wiring phase sequence requirement is that there are three sets of wires in total. Please distinguish them clearly during use and strictly follow the wiring diagram,

Require all wires to be tightly connected to the thyristor and led out to the instrument.

2Check that all wiring terminals are connected correctly and the power can be turned on. At this point“%'The window is on, and the voltage adjustment indicator light is on

(Or the power adjustment indicator light is on)

3, will“Output regulation'Turn the dial left to the starting point.

4, Press“manual/automatic'Select the output mode button, press the manual output indicator light once, and press the automatic output indicator light again.

5Lightly press“pressure regulation/Adjusting skills'Select the button to trigger the thyristor working mode, which can change the thyristor working mode (at the factory)ZK-3CSet in Adjustment

Press trigger state or set working state according to user requirements.

6Adjust and correct“Output regulation'Dial and observe simultaneously“%'Display window, adjust to the output power you need, and the instrument will enter the trigger mode at the same time

Control the working status of silicon.

7The instrument is set in“pressure regulation'When triggering the thyristor working mode, the output is voltage regulation mode (phase-shifting type).

8Lightly press“close'Key, the instrument stops working.

9The instrument has a power-off automatic shutdown function.

10Built in instrument panel6Digital function switch:

The instrument movement and housing are designed with a plug-in method, and the switch is located behind the display panel. Users can extract the instrument movement according to on-site operating requirements and set it according to the function table.
