5. Switch the machine disconnect to ON position, and latch the electrical control box door
security switch. Use extra caution when working inside the panel with the machine power
on.
6. Check if green lights (L4, L5, and L6) on the card are all on. This indicates that the voltages
to and from the card are correct.
7. Using a voltage meter, perform the following tests once the card is installed.
7.1.
Inspect the “Film Force” speed potentiometer:
7.1.1. Check the resistance between wire #51 and #53 on the “Film Force” speed
potentiometer connection the on back side of the main operator panel. The
resistance should be 5K
Ω
.
7.1.2. Check the resistance between wire #51 and #52 and turn the “Film Force”
dial. The resistance should increase as the dial is turned clockwise, and
decrease as it is turned counter-clockwise.
7.1.3. Check the resistance between wire #51 and #53 on connector P3. The
resistance should be 5K
Ω
.
7.1.4. Check the resistance between wire #51 and #52 and turn the “Film Force”
potentiometer dial. The resistance should increase as the dial is turned
clockwise, and decrease as it is turned counter-clockwise.
7.2.
Inspect the dancer bar speed potentiometer dial:
7.2.1. Locate the dancer bar speed potentiometer on top of the carriage. Check the
resistance between wire #67 and #69 on the potentiometer connection. The
resistance should be 5K
Ω
.
7.2.2. Check the resistance between wire #67 and #68 on the dancer bar
potentiometer connection. The resistance should be about 1.1K
Ω
with the
dancer bar at home position and increase as the dancer bar is extended.
7.2.3. Check the resistance between wire #67 and #69 on connector P3. The
resistance should be 5K
Ω
.
7.2.4. Check the resistance between wire #67 and #68 on connector P3. The
resistance should be about 1.1K
Ω
with the dancer bar at home position and
increase as the dancer bar is extended.
7.3.
Check the voltage between wire #AC0V and wire #AC12V on connector P2. It
should read around 12 VAC.
7.4.
Check for continuity between wire #72 and (-) on connector P1.
7.5.
Run the turntable in Manual mode, and check for continuity between wire #72 and
#54.
7.6.
Run the turntable in Manual mode, and check the voltage between wire (A) and #72
on connector P1. It should read around 9 VDC with the turntable at full speed and
approach 0 VDC as the turntable is slowed down.
