Rapid-Air CABINET REEL: R50, R60 & R70 SERIES - Manual (Page 9)

4. Percent speed pot set too low.
a. Adjust percent speed pot to 100%.
5. Fuses blown.
a. Check fuses on DC drive board.
6. No AC voltage at DC drive board.
a. Check wiring.
7. Check Signal voltage between P2 to I2 on DC drive.
0-6 VDC—Ramm
0-9 VDC—Regen Drive
while moving dancer arm.
a. If there is a signal, check continuity between I1 & I2.
If continuity, replace 69100035 board or call factory.
If no continuity, replace D.C. drive or call factory.
8. Check line voltage input of 69100034 board, 120 VAC, TB-1
a. Check wiring. Call factory.
9. Check pico fuse 69100034 board (f1).
a. Replace fuse—call factory.
10. Check for 0—12 VDC between pin #1 (+V) and pin #2 (GND) of panduit connector TC3 on
board #69100034.
a. If no voltage present call factory.
11. Check for DC voltage between pin #6 (V0) and pin #2 GND of panduit connector TC#, on
board #69100034, while moving the dancer arm from minimum to maximum position.
a. If voltage is present, turn power off and check the ribbon cable connections between
panduit connector #TC3 of 69100034 board and panduit connector #TC3 of 69100035
board and panduit connector #PT3 of 69100053 board. This should be a continuity
check for tight connections. Call factory for assistance.
b. If voltage is not present move on to step 12.
12. Check voltage between pin #2 of TB-2 & pin #5 of TB-7 on 69100053 board while moving
the dancer arm from minimum to maximum position.
a. If voltage varies 2.5-4 volt from minimum to maximum position, the dancer arm pot
is OK, but the 69100034 board could be defective. Call factory.
b. If voltage does not vary when moving the dancer arm from minimum to maximum
position—call the factory for assistance.
