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.
3) After replacement, install the fuse box back to original position, as
shown below.
2.7 Output Verification
Output verification verify that the power supply outputs the correct voltage and
current levels and properly responds to entries from the front panel.
Voltage Output Check
The following steps verify basic voltage functions without load.
1. Turn on the power supply.
2. Enable the outputs.
Press [On/Off] key to turn off the OFF annunciator and turn on the CV
annunciator.
Notice: if the voltage value flash, then the power supply is in Set mode,
‘‘Set mode’’ means that the VFD display shows the setting output voltage
and current. Or the power supply is in Meter mode, ‘Meter mode” means
that the VFD display shows the actual output voltage and current and the
“Meter” annunciator is lit.
3. Check that the front-panel voltmeter properly responds to numeric keys.
Set some different voltage values, then wait till the Meter mode to check if
the VFD displayed voltage value is the same as the set voltage value, and
to check if the VFD displayed current value is nearly zero.
4. Ensure that the voltage can be adjusted from zero to the full rated value.
