Table 1: Defines of interface

• Digital IO interface: PIN 1 to 3 is a dry contact output interface with complementary functions of normally open and normally closed. PIN2 is the common end of the dry contact. Dry contact output capacity: 1A/30VDC or  0.15A/220VAC; PIN 5 to 6 are dry contact input interfaces, which can be set for external control of the output, external fault feedback, or external control of the buzzer;
• Analog interface: Analog interface is optional, interface signals can be customized, two analog interface definition as shown in the table above
• RS485 interface: Serial communication interface(Female), software using standard Modbus-RTU protocol;
• CAN interface: CAN1 and CAN2 are two internal parallel CAN bus interfaces, which facilitate serial or parallel connection between devices. CAN communication also be used for communication between external devices;
  Note ：Analog interface is optional interface (customizable) , up to a maximum of four analog, two analog input and two analog output. Select 1-2 analog, interface see figure above; select 3-4 analog, interface is RJ45-CAN1, 1-8 pin  is defined as the positive and negative of analog input 1, the positive and negative of analog input 2, the positive and negative of analog output 1, the positive and negative of analog output 2. If you need analog function, please inform us of the specific requirements in advance。

1.2 Voltage compensation

To use the remote voltage compensation function, use twisted-pair cables with high insulation. Positive and negative cables can not be connected inversely, as shown in the figure above. When not in use, the compensation terminals (SENSE) PIN1 and PIN2, PIN3 and PIN4 need to be shorted with short cables.
1.3 Parallel connection The device identifies and controls the parallel output through CAN communication. The diagram above shows the parallel connection.
Note:120 ohm is the CAN bus terminal resistor.

2.1 Display area
The Home displays real-time operating status information of the device, including:

• Display area: Current real-time output information;

• Setting area: setting of voltage, current and power reference values, And
  voltage/current priority Settings;

• Status area: buzzer, lock key state, date and time information, working time, and dry
  contact and application mode state (gray);

• Mode area: Control mode and output mode;

• Series/parallel status area: when multiple machines are used in series/parallel, each
  device will display master/slave machine number and CAN data receiving and
  receiving status of the machine (gray);

Note:

1. Display elements of the status area can be hidden. When an application mode is enabled, the status of the application mode will be displayed, and when the dry contact is used, the corresponding status icon will be displayed.
2. Output mode is divided into common mode and application mode. 1. Common mode:
   CV(Constant voltage), CV(Constant current), CP(Constant power) or CV/CC/CP (Output is not open); 2. Application mode: such as CV Steps(Constant voltage steps), CC Steps(Constant current steps) and Hybrid steps in step mode.

2.1.1 Home

Three Homes, including:

• Home: displays the most comprehensive real-time working status information, detailed in the section of “Display Area”;
• Auxiliary Home: maximizes the real-time output information;
• Waveform Home: displays output real-time information in an intuitive waveform manner.

Note:

1. The Home is the only interface for setting voltage, current and power reference values.
2. Press “ENTER” to set the sampling rate of the waveform displayed on the waveform Home. Whether the voltage, current and power waveform are displayed can be controlled by pressing “VOLT”, “CURR” or “POWER” key.

Note:

1. Common mode data includes voltage, current and power reference values as well as parameters of function setting and protection setting in user Settings.
2. When the key triggers the setting of reference value, the preset area will be displayed above the corresponding operated element in the setting area. Enter a preset value through the number or knob key; When the knob triggers the  setting of reference value, the corresponding bit of the element to be operated in the setting area will flash.

HW Over-Volt P| The hardware over-voltage circuit detects an over-voltage error| Confirm start overshoot or steady overshoot (overshoot in working process), if it is start overshoot, can set “priority” to “current priority”, can also set “Rise Time Of Volt” parameter to a reasonable value(voltage priority); If it is a steady state overshoot and the voltage is not more than
1.3 times the rated voltage, you can turn off the hardware overvoltage protection function. If the voltage is more than 1.3 times   the   rated voltage,   install   an anti-reverse diode on the output side.
HW Over-Curr P| The hardware over-current circuit detects an over-current Error| Confirm start overshoot or steady overshoot (overshoot in working process), if it is start overshoot, can set “priority” to “voltage priority”, can also set “Rise Time Of Volt” parameter to a reasonable value(voltage priority); If steady-state overshoot occurs, disable hardware overcurrent Protection.
Over-Volt P| The software detects an over-voltage error| Confirm start overshoot or steady overshoot (overshoot in working process), if it is start overshoot, can set priority to “voltage priority”, can also set “Rise Time” parameter to a reasonable value; If the overshoot is steady state, the “over- current protection value” or “overcurrent duration” can be appropriately increased;
Over-Curr P| The software detects an over-current error| Confirm start overshoot or steady overshoot (overshoot in working process), if it is start overshoot, can set “priority” to “voltage priority”, can also set “Rise Time Of Curr” parameter to a reasonable value(current priority); In the case of steady overshoot, the “overcurrent protection value” or “overcurrent duration” can be appropriately raised.
