• If the tone did not cease, check the DC Voltage to the Proces-
sor by accessing the Diagnostic Menu
H0
. If the voltage is
adequate, replace the Processor.

B5-3.1 One Long - Two Short Tones
This tone indicates that the feedback signal, which represents
the position of the Servo 2 cross-bar, is out of expected range.
This tone will be accompanied by Error Code 66 or 67.
• If Error Code
66
is displayed, the signal received from the
feedback potentiometer is higher than expected. This is due
to one of the three following reasons:
1. The orange wire (ground) between the potentiometer
and plug are not making contact, or have a high resis-
tance contact.
2. The potentiometer is out of calibration.
3. The potentiometer is defective.
• If Error Code
67
is displayed, the signal received from the
feedback potentiometer is lower than expected. This is due to
one of the following reasons:
1. The green (signal) or orange (reference voltage) wires
between the potentiometer and plug are not making
contact or have a high resistance contact.
2. The potentiometer is out of calibration.
3. The potentiometer is defective.
4. The Control Circuit is defective.
The Servo 2 feedback signal can be viewed within the Diagnostic
Menu. The Value displayed depends on the direction and
amount of push-pull cable travel. As a general rule:
• When the Value displayed is
1023
or
0
, the problem is with
the wiring between the potentiometer and plug.
• If the displayed Value varies, the potentiometer is defective.
• When the Value is slightly too high or too low when fully
extended, the potentiometer requires calibration.
B5-3.2 One Long, Two Short - High Repetitive Rate Tones
This tone is also referred to as a Jam Tone. When sounded, Servo
2 is unable to reach the commanded position. In most cases
when a Jam Tone is encountered, it can be cleared by moving the
Control Head lever back to the point prior to where the tone was
first encountered.
The tone will be accompanied by Error Code 65 and is typically
caused by one of the following reasons:
• Stiff or frozen selector lever.
• Misadjusted push-pull cable.
