“FactoryCal.Data Lost”.
If the system setting data in EEPROM is lost,the VFD will display
“MainframeInitializeLost”.
Exception handling
If the power supply can not start normally, please check and take measures by reference to
steps below.
1. Check whether the power cord is correctly connected and confirm whether the power
supply is powered.
Correct wiring of power cord = > 2
Incorrect wiring of power cord = > Re-connect the power cord and check whether the
exception is removed.
2. Check whether the power in On. Power key is under “ ” On status.
Yes = > 3
No = > Please check the Power key to start power and check whether the exception is
removed.
3. Check whether the fuse of power supply is burned out.
If yes, change fuse. Detailed steps:
1. Use a screwdriver to push and turn the fuse box on the rear board of the power
supply, refer to the below picture. After the fuse box is opened, you can see the
fuse in it. Please replace with a fuse of the same specification.
2. If the fuse is fused, please change fuse of same specification based on machine
model. See the table blow for matching information of fuse and machine model.

Set different voltage and check whether the VFD display voltage is approximate to the
setting voltage.
6. Ensure the output voltage can be adjusted from 0V to full rated value
Output current checkout
The following steps check basic current functions with a short across the power supply’s
output
1. Turn on the power supply.
2. Disable the output
Press key to ensure that the output is disabled.
3. Connect a short across (+) and (-) output terminals with an insulated test lead.
Use a wire size sufficient to handle the maximum current.
4. Enable the output and open the Meter function button
To ensure the CC indicator lamp is lit
5. Adjust the current
Set different current values and check whether the voltage display is approximate to
0V,the display current value is approximate to the setting value
6. Ensure that the current can be adjusted from zero to the full rated value.
7. Turn off the power supply and remove the short wire from the output terminals.

3.1 Local/Remote
You can switch from remote mode to local mode by press + buttons.
When you turn on the unit,it will default in local mode and all buttons are available.That’s
to say,in remote mode,the front board buttons can not be used.The two operating mode can
be switched through PC.When the operating mode is changed,all the output parameters
will not be effected.
3.2 Setting voltage
The constant voltage range is from 0V to the maximum voltage value. It is very easy for
you to set the constant voltage output. You have 3 solutions to set the constant voltage
value.And when you press ,this button will be lit.
directly input through number keys
Input the value you want to set and then please press or button to
confirm.
