7.5 ADJUSTMENT WHEN THE SERVICE PANEL ASSY IS REPLACED

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
A
panel for service.
Note: Enter the values, using an RS-232C command or the Factory Menu.
(Rear of the Panel)
Using an RS-232C command
Enter a "PFY" command with Factory mode ON.
B
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 or the Factory Menu.
There are two types of hour meters. Do not take the MTB hour meter for the hour meter.
Using an RS-232C command
To acquire the accumulated power-on time of the product itself, use the "QS2" of RS-232C command.
1. To clear the data on the hour meter (for the Panel) : CHM
2. To clear the data on the pulse meter
3. To clear the data on the SD history
E
4. To clear the data on the PD history
Using the Factory Menu
See "7.1.6 HOW TO CLEAR HISTORY DATA."
