3600 SERIES USER MANUAL

The following general safety precautions must be observed during all phases of operation, service, and repair of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. The Manufacturer assumes no liability for the customer’s failure to comply with these requirements.

Attention

I. Safety

1. Users should operate according to this manual.

2. There is high voltage inside the instrument, please avoid touching it directly.

3. Please read the user manual carefully before you use the instrument to assure your

safety.

4. Ground the Instrument

This product is provided with a protective earth terminal. To minisize shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. The instrument must be connected to the AC power supply mains through a three-conductor power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power outlet.

5.Keep Away From Live Circuits

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified service personnel. Do not split the components when power cable connected.

Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before touching components.

Do Not Substitute Parts or Modify Instrument

Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to a qualified dealer for service and repair to ensure that safety features are maintained.

II. Connecting the power line

1. Inspect the power selection switch on the back panel, to assure if the selected voltage is the same as environment power voltage. If not, please refer to the notice around the power plug.

2. Before connecting the power supply, please be sure that the switch on the front panel should be in the off position.

3600 SERIES USER MANUAL

For example, how to set up the output voltage at 24.3V

1. T o set up by using number keyboard

Step1. Press “V-set” button, Step2. Enter the password by using the number keypad (if the keypad is unlocked, please do step 4), Step3. Press Enter button (if the password is wrong, please do step2 for reentering), Step4. Press “2”, “4”, “.” and “3” button to enter the voltage value, Step5. Press “V/A” button to confirm the voltage value.

2. T o set up by using Rotary knob

(1) If the keypad is unlocked by password, directly rotate the “Rotary knob”, and the voltage will be continually changed from the previews value according the rotation. At the beginning, the cursor will be shown on the last number of the value which is indicated on the LCD, you can move the cursor to the first number, second number etc by using “ ”and “ ” buttons, and then rotate to change each number, and let it stay at 24.3 V, then confirm the value by pressing “V/A” button.

(2) If the keypad is locked by password Step1. Press “V-set” button, Step2. Enter the password by using the number keypad, Step3. Press Enter button (if the password is wrong, please do step2 for reentering), Step4. Rotate the Rotary knob button to change the value, the operation is as same as item(1) Step5.

3600 SERIES USER MANUAL

2.3.2 Set up current

3600 Series power supply can be set up for a constant current or a maximum current, please see

the following example.

Conditions: voltage=24V, load R=12Ohm, then V/R=2 A, it represents the power supply provide the load with 2A current. If the current value is set to 2.50A, the power supply works in CV mode, the actual current value should be displayed on the screen as 2.00A. If the load resistor becomes lower, the current will increase. When the current exceed 2.5A, the power supply will change to CC mode, and the output voltage will drop down to maintain the actual current value to 2.5A.

Set up current procedure as follows:

Procedure Operation details LCD display Step 1 Press “I-set” ENTER PASSWORD

Step 2 Enter the password ( Or jump to step 4 if the ENTER PASSWORD keypad is unlocked) Step 3 Press “Enter” button ( it will return to step 2 if your ENTER PASSWORD password is wrong for reentering) **** Step 4 Press “I-set” . Set up a constant current or a maximum SET CURR=0mA current by using number key or the rotary knob. NEW=3 Step 5 Press “V/A” or “mV/mA” to confirm the set. SET CURR=0mA It will return to step 4 for reentering if the current NEW= 15.0 value exceeds the maximum output current. It will exit the setting up current operation at any procedure by press ESC button

2.3.3 Enable/disable the output

By default, the power supply is disabled after power on, users can change the output status by using ON/OFF button. The button is a turnover button. When the original output is ON, press

3600 Series Programmable Power Supply VERSION 2.0 2004.6

it then the output will be changed to OFF status, vice versa.

2.3.4 Store parameters

If you often use a voltage and current as 24V and 2A or 12V and 2.3A and etc, you just need to set up the data at the first time and then store the data in the power supply. When you need it, recall it. 3600 series power supply can store up to 10 sets of parameters.

The parameters include 1) Voltage value; 2) Current value; 3) Maximum voltage; 4) Locked/ unlocked keypad; 5) Maximum power ; 6)Baud rate; 7) Communication address.

The store operation always be done after setting up V-set, I-set etc, the operation is as follows:

Procedure The operation Methods LCD display Step 1 Press “Store” button ENTER P ASSWORD

3600 SERIES USER MANUAL

Step 2 Enter the password ( Or jump to step 4 if the keypad ENTER PASSWORD

is unlocked)

And click the “OK” button and the page key “ADDRESS” are out of work. And vice versa. (And users must be in the identity of the “Manager” otherwise the “ADDRESS” cannot be used.

Fig 4-4 COM Port Failure Opening frame

Set Default POWER Address: The system will automatically be in the networking state after the start according to the default COM port and the default POWER. It is just needed to enter the address in the “Default POWER” bar.

Set POWER Address: Login in the identity of the “Manager” and select the existing COM port. Then the “ADDRESS” page key will be available.

In Fig. 4-5, enter the default address (245) of the power supply and then click “READ”. If testing successfully, the “NEW ADDRESS” and “WRITE” functions will be available. If testing failure, then the new address of the power cannot be set and the prompting diagram as shown in Fig. 4-6 will be displayed. This time the communication cable must be checked.

Fig 4-6 Communication Failure

Explanation: For the first installation each POWER must be deployed with but one address in order to communicate correctly. Set the parameter and select “OK” and it will enter into the common communication. The default COM port is COM1 and the default POWER address is 0.

4.3 Start the Communication

After the COM port and ADDRESS set, select the button and the system will start the communication. If the communication is normal, the prompt information as shown in Fig. 4-7 will be displayed. And if the communication is failure, the prompt information as shown in Fig. 4-8 will be displayed.
