1. Setting change of Auto Power Save and Auto Shut-Off Mode at the time of shipment

Setting at the time of shipment in the above modes has been made not to permit operation but the setting values have been changed as follows.

Before Change After Change Auto energy saving (08-11) Auto shut-off (08-56)

Note) *The power switch automatically goes off when the [Auto shut-off] mode is operated.

Return to the READY condition can be made by turning the power switch ON.

* Operation time of [Auto energy saving] [Auto shut-off] can be extended to a maximum of

240 minutes.

*The power supply OFF in the [Auto shut-off] mode has priority over the Weekly Timer.

Therefore, when the power supply is turned off in the [Auto shut-off] mode, the power return function of the Weekly Timer cannot operated.

*If the setting value changes, refer to BSI/F98C249.

2. Change of power supply switch to one with an electromagnetic reset function In order to be able to reset the MAIN SW using software, change has been made to the power supply switch by giving it an electromagnetic reset function. This switch has a MAIN SW inside coil for resetting and the switch goes off when DC24V is added to the coil. The combination of the switch terminal and the harness connection has also been changed as shown below.

3. Change of logic circuit (PWA-LGC) In order to drive the power supply switch with the above magnetic reset function, the logic circuit has been changed. PWA-LGC has been changed to all regions.

(Details)

Connection of the 130 pin of IC31 (95CO63F) and the 14 pin of IC33 (62308F)l Connection of the 15 pin of IC33 (62308F) and the A9 pin of J8l To distinguish easily between the current and new logic PC boards, the color of the PC board l has been changed from white to yellow.

Note) The current logic PC board should never attached to machines complying with the

ENERGY STAR (Tier 2). If there is an excess current flow to the MAIN SW, it might possibly break.

4. Wiring Change (Harness added) In order to drive the switch with the power supply magnetic reset function, the wiring has been changed as shown below.

Between the connector J8 (A9, A10) of the PWA-LGC and the MAIN switch (+, - terminal) have been connected by two new harnesses. Also, the harness of the PWA-LGC side is not considered as a service part but is a part of the previous harness (WH-LGC-HVT).
