NH Bale Monitor problem
Posted 06 August 2012 - 08:03 PM
Is this just a sticky relay issue, if so, how can I test each relay?
Thanks for any assistance.

The Bale Monitor Beeps continuously until the bale is ready and THEN quits beeping - just the opposite of the way it used to work. Once the bale is ejected, it begins beeping again.
The system works like this. When the auto-wrap is not tripped the roller on the switch arm is in the notch of the cam preventing the circuit from completing. When you reach the point where the auto-wrap is tripped to tie, the cam rotates and pushes the arm and roller closer to the switch completing the circuit and the alarm sounds. As the cam continues to rotate the high side of the cam moves away from the roller and the arm moves away from the switch and the alarms stops. The cam continues to rotate and when the high side comes around again it pushes the roller and arm closer to the switch causing the circuit to complete momentarily and the alarm sounds to alert the operator the tying cycle is complete. The cam continues to rotate until the roller to falls in the notch at the completion of the tying cycle and silences the alarm.
Since the alarm stops beeping when it starts its tying cylcle indicates the switch is working and the wiring is good. Did you trip the auto-wrap to start the tying cylce and then shut the pto off once the high side of the cam was past the switch? When the cam is away from the switch you can manually move the arm with the roller on the swtich to check if the alarm sounds when the arm is closest to the switch and silent when it is away from the switch.
The switch is mounted in sloted holes and even if the roller is in the notch of the cam the adjustment may not be correct and the swtich is still completing the circuit.

Thanks very much for the detailed responses and I appreciate the info Mike on the way the autowrap works w/ the sensor - really helped me understand it!
