When the Panel Assy is replaced with one for service, the following adjustments are required:
Adjustments of Vofs voltage and Vyprst voltage
Enter the reference adjustment values for the Vofs voltage and Vyprst voltage that are written on the label attached to the
panel for service.
Note: Enter the values, using an RS-232C command.
(Rear of the Panel)
Enter to "module adjust mode on" of the panel control in the factory menu before beginning the adjustment.
( refer to "8. service factory menu" on SM)
Using an RS-232C command
Enter Module Adj. mode (Refer to " 8. MODULE ADJSTMENT MODE").
Enter a "PFY" command with Factory mode ON.
Convert the adjustment voltage values written on the label attached at the rear of the Panel to an input command, referring to
the conversion chart. (See the next page.)
• Reference adjustment of the Vofs voltage: Ex. "Vofs = 35" → (Check the conversion chart.) Enter "VOF112."
• Reference adjustment of the Vyprst voltage: Ex. "Vyprst = 270 V" → (Check the conversion chart.) Enter "VRP078."
Clearing data on various histories of the Panel, such as those on the hour meter
• It is necessary to clear the data on the hour meter, etc. to match them to the actual driving hours of the Panel.
• It is also necessary to clear the data on SD and PD, because the accumulated power-on time when a shutdown or power-
down occurred is recorded.
Note: Clear the values, using an RS-232C command.
