10.5.1.3 Steady Tone
The Steady Tone is an indication to the operator that something has gone wrong within the Control
System. The Steady Tone will typically be accompanied by an Error Message on the Processor’s
Display. If the tone is heard, the Processor’s Display must be referred to in order to further diagnosis the
problem.
The Transfer Button is shorted - Tone will cease when command is taken at another Station.
If the Transfer Button becomes shorted for 12 seconds or more during Normal Operation, a steady tone
will be produced at all Remote Stations as long as the Transfer Button remains shorted. Full System
control remains. Transferring to another Remote Station silences the Steady Tone. Command cannot
be regained at the Station until the problem is rectified.
10.5.1.4 Three Second Steady Tone
This tone could indicate one of three things.
• Transfer Button on the Control Head in command is stuck.
• If the Processor for this System includes the use of Back-up Mode, this tone would indicate
that there has been a switch closure requesting Back-up Mode.
• If the Processor for this System includes Integrated Solenoid Trolling Valve control, this tone
would indicate that there has been a Troll Solenoid error. Refer to the Error Code displayed.
10.5.1.5 Three Second Steady Tone, followed by a Slow Repetitive Tone
This tone indicates that there has been a shorted Transfer Button on power-up. Command can be
gained at any other Remote Station, which silences the Slow Repetitive Tone.
10.5.1.6 Five Seconds On, Five Seconds Off - High Repetitive Rate
Tone
Loss of communication with Station Expander (SE) or the Troll Actuator (p/n 9001). This tone cannot
be cleared unless all Error Codes (Active and In-Active) have been cleared.
10.5.1.7 Five Second Steady Tone
Loss of Serial Communication.
10.5.2 Servo 1 Control System Tones
10.5.2.1 One Long - One Short Tone
This tone indicates that the feedback signal, which represents the position of the Servo 1 cross-bar, is
out of the expected range.
This tone will be accompanied by Error Code 63 or 64.
• If Error Code 63 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 resistance contact.
2. The potentiometer is out of calibration.
3. The potentiometer is defective.
• If Error Code 64 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 1 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.
