7005 STEPPER

CHECKING Q2

1. Unplug all connections.

2. Set voltmeter to audible continuity.

3. Probe across GND (CNT1) and the L2

terminal.

4. If it beeps the Q2 transistor is BAD.

5. Replace Drive board.

6. Also test as follows:

I. TRANSFORMER (AC)

1. Unplug Transformer from Rectifier Board.

2. Feed Red / red wires from safe 120 VAC source.

3. Set voltmeter to VAC.

4. Check voltages as follows:

Red / red = 117.7 VAC

Yellow / yellow = 10.46 VAC

White / white = 40.10 VAC

NOT

USE

CON 2

CON 1

II. RECTIFIER BOARD (DC)

1. Inspect 3amp fuse.

2. Plug in Transformer (CON1) and AC

(CON2) into Rectifier Board, unplug

everything else and turn ON unit.

3. Set Voltmeter to DC and check as follows:

White / Black = 13.98 VDC

Green / Black = 19.07 VDC

III. DRIVE BOARD (DC)

CNT4

CNT3

L2 L1

CNT1

1. Plug in Rectifier Board to Drive Board

only (CNT1). Leave CNT3, CNT4 and

L1/L2 unplugged.

2. Set voltmeter to VDC and check at

CNT1 as follows:

VCC / GND = 13.11 VDC

VBB / GND = 27.67 VDC

3. Plug in Ribbon Cable (CNT3) and check

as follows:

VCC / GND = 11.70 VDC

IV. SENSOR (DC)

1. Plug in sensor (CNT4) to Drive board.

2. There is no need for stepping to check the following:

Black / Green = 5VDC (voltage from Drive Bord to Sensor)

Red / Green = 4.3 VDC (voltage from Sensor to Drive Board)

V. MAGNET (DC)

1. Ohm out magnet (Unplug magnet wires)

2. Set voltmeter to Ohms and check across magnet wires:

Blue / Blue = 8.6 ohms

3. Plug in Magnet (L1/L2) to Drive Board

4. Set Volmeter to DCV

5. Stepping on unit and check resistance as following:

¾ Level 1 ( 25 step/min) = 13.98 VDC

¾ Level 2 ( 30 step/min ) = 12.8 VDC

¾ Level 3 (35 step/min) = 11.9 VDC

¾ Level 4 (40 step/min) = 10.9 VDC

•

¾ Level 28 (160 step/min) = mili volts
