EX Series Operating Manual
1-3. Inspecting the Unit.
When you receive your power supply, inspect it for any obvious damage that may have
occurred during shipment. If any damage is found, notify the carrier and the nearest ODA
Sales Office immediately. Warranty information is shown in the front of this manual. Keep
the original packing materials in case the power supply has to be returned to ODA
Technologies in the future. If you return the power supply for service, attach a tag
identifying the owner and model number. Also include a brief description of the problem.

Electrical Check
▌When turning on the power, check the alarm sound.
If the alarm sounds, the instrument has the error during self-testing itself.
Error checking, press the error key and conform error code.
More information about error code, refer to “7.Error Messages”.
About Self-test, refer to 『1-6. Check after Power On』.

EX Series Operating Manual
Power Cord Check
▌Your power supply is equipped with a 3-wire grounding type power cord; the third
conductor being the ground. The power supply is grounded only when the power-
line cord is plugged into an appropriate receptacle. Do not operate your power
supply without adequate cabinet ground connection.
Input AC Power Line Check
▌You can operate your power supply from a nominal 198~242 V single phase AC
power source at 47 to 63 Hz. AC100V, 110V, 115V, 230V input power is optional.
Refer to chapter "1-2. Accessories & Options"

The power-on test includes an automatic self-test that checks the internal microprocessors
and allows the user visually to check the display. You will observe the following sequence
on the display after pressing the front panel power switch to on. And also keep the
ex-remote and voltage value is zero and current value is max value.OVP & OCP level are

EX Series Operating Manual
1. POWER switch.
The power supply is turned on or off by this switch. It is adopted by following power supply's
capacity.
2. Ventilation slit.
Air flow flows from front ventilation slit to rear ventilation slit compulsorily.
3. 16Character, one line LCD Display.
Voltage/current and , all kinds menu/message displayed.
4. Error Lamp.
Error occurs, LED is lit. After checked all errors, LED is turned off.
5. Limit Display Lamp.
When the instrument is under the setting of Volt/Curr, LED is lit. If the device is output on state,
LED is turned off.
6. Key Lock Lamp.
If Key lock lamp is turned on, front panel keys are not working.
7. Remote Interface Lamp.
When received the remote control signal from PC, PLC and etc, it lights and automatically,
front panel keys are under "Key Lock" state.
8. CV Mode Lamp.
The power supply is in constant voltage mode.
9. CC Mode Lamp.
The power supply is in constant current mode.
10. Voltage Encoder Knob.
Adjusts the output voltage, the over-voltage protection level, the under-voltage limit
and numeric value changing of other menu.
11. Current Encoder Knob.
Adjusts the output current, the over-current protection level, the under-current limit
and numeric value changing of other menu.
12. Volt Cursor or Menu Change Key.
Move the under bar digit to the left about voltage. It also is used to move to next menu
hld d
when selected menu mode.
13. Curr Cursor or Menu Change Key.
Move the under bar digit to the right about current. It also is used to move to next menu
when selected menu mode.

Displays error codes generated during operation and self-test.
16. Protection Setting and Front-panel Lock Key
Enables or disables the OVP/OCP/UVL/OVL/UCL/OCL protection function, sets trip voltage
level, and clears the overvoltage condition. Also during 1 sec press this key, you can lock
pront panel operating with lighting LOCK lamp. One more press this key during 1 sec,
pp p g gg p p y g
clear the lock key.
17. Volt/Curr Setting Limit Display Key.
Shows voltage and current limit values on the display and allows knob adjustment for setting
limit values with lighting LMT lamp. One more press this key during 1 sec, return to previous
state. You only see the setting value not just real output value.
18. Store or Calibration Key.
Stores an operating state(voltage, current, OVP, OCP and other state) in location ‘‘1’’, ‘‘2’’,
‘‘3’’ or another number / enables calibration mode with pressing this key and put the AC power
on.
19. Recall or Factory Key.
Recalls an operating state(voltage, current, OVP, OCP and other state) in location ‘‘1’’, ‘‘2’’,
‘‘3’’ or another number / enables factory mode(Memory Initializing, ,Auto Cursor Move, Auto
Key Lock, OVP Disable, OCP Disable, ADC Sampling, Calibration Restore, Calibration
Backup, Calibration Factory Default Recover and etc) with pressing this key and put the AC
power on.
