11) Connect the “COM“ side of the tester to the “N” terminal
of driver and the “V
” side of the tester to “T/RB” of
driver, measure the diode voltage.
Voltage should be “OL” (Over Load).
Replacing driver - (

GC 60 DCI
Remove all the terminals of the driver before checking.
If items 1) to 8)
are performed and the results are satisfactory, driver is normal.
Use a digital multi meter in diode checking function
1)
Connect the “COM“ side of the tester to the “CAPA-”
terminal of driver and the “V
” side of the tester to “LIVE”
and “NEUTRAL” of driver, measure the diode voltage.
Voltage should be “OL” (Over Load).
2)
Connect the “V
” side of the tester to the “CAPA-”
terminal of driver and the “COM” side of the tester to
“LIVE” and “NEUTRAL” of driver, measure the diode
voltage.
Voltage should be 0.4~0.8VDC.
3)
Connect the “COM“ side of the tester to the “CAPA+”
terminal of driver and the “V
” side of the tester to “LIVE”
and "NEUTRAL" of driver, measure the diode voltage.
Voltage should be 0.4~0.8VDC.
4)
Connect the “V
” side of the tester to the “CAPA+”
terminal of driver and the “COM” side of the tester to
“LIVE” and "NEUTRAL" of driver, measure the diode
voltage.
Voltage should be “OL” (Over Load).
