You can observe the bus voltage with a voltmeter connected to the POSITIVE BUS and NEGATIVE

BUS terminals on the Capacitor Board. This board is located on the right sidewall of the drive behind the

front panels (see page 26). The Bus terminals are near the top of the drive. BE CAREFUL. THESE

TERMINALS MAY HAVE POTENTIALS UP TO 800VDC!!

There are LED indicators on the Current Controller board (see the layout on page 28). The action of

some of these LED's is indicated in the graph above and on subsequent pages.

The POWER LED (it is GREEN in color) comes on as soon as the main power is turned on. This

LED operates from the +24VDC raw power supply. If this LED does not come on, you should check the

incoming power, main fuses and power transformer fuse.

While the bus is charging, the BUS LED lights up RED in color. When the bus reaches a level of

approximately 35VDC below the nominal bus level, a contactor energizes to bypass the charging resistor.

The BUS light then changes to GREEN in color. If the light does not change to GREEN within 30 seconds,

turn off the input power and attach a meter to the bus terminals to monitor the bus voltage. See the

troubleshooting section for assistance.

On the Current Controller board, there are three LED's labeled HS1, HS2, and HS3. These are the

encoder position indicators. One or two of these indicators should be on. If none are on or if all three are

on, there is a problem. Refer to the troubleshooting section. The TAC LED may be off or RED or GREEN.

It is not important at this time.

The ENABLE LED should be off.

Once the bus has charged up and the BUS LED is GREEN, you may proceed to the next section.

A GREEN LED on the Bus Loader should be ON, but the RED LED on the bus loader must be OFF.
