Table 4–6: Service Aid 111 Switch Functions

Switch Function During Test

1 Causes supply motor to rotate clockwise (MAN SPLY test) or the take-up motor to rotate

counterclockwise (MAN TKUP).

2 Causes the take-up motor to rotate clockwise (MAN TKUP test) or the supply motor to

rotate counterclockwise (MAN SPLY) test.

3 Reverses motor direction.

4 Exits the service aid.

5 Exits any test and returns to the MODE ? prompt.

At the MODE? prompt, the oscillation test (Auto OSC), the supply motor test (MAN SPLY), or

the take-up motor test (MAN TKUP) may be selected by pressing switch 1, 2 or 3, respectively.

After selecting the test, switch 5 must be pressed to start the test.

The auto oscillation test (AUTO OSC) cycles the take-up and supply motors in alternate

directions. The supply motor test (MAN SPLY) and the take-up motor test (MAN TKUP)

operate their respective motors in either the clockwise or counterclockwise direction. The

initial motor speed is zero. By pressing continuously on either switch 1 or 2, the speed

increases to the maximum capability of the motor in the direction speciﬁed in Table 4–6.

Pressing continuously on the other switch (2 if 1 was pressed initially, or vice versa) decreases

the speed to zero, reverses direction, then increases the speed to maximum in the new

direction.
