Sum = 5.120 (inches of stroke)
Repeat the procedure for position 2, and compare the inches of stroke measured to the inches of stroke
observed. A change in reading between 2 points on the stroke is a general indication of proper system
operation.
NOTES:
* It is common practice to apply earth ground to power supply terminals near power supply.
** Jumpers W 20 and W 22 make P1 Pin 24 inhibit and P1 Pin 3 latch pulse
Jumpers W 21 and W 23 make P1 Pin 24 latch pulse and P1 Pin 3 inhibit.
