CONTROL AND MONITORING SYSTEM
Type microprocessor controlled electronics
Baler controls
• Plunger load to control bale density, alarm volume,
displays, reset field bale counts and bale weight
average, manual hydraulic pressure control
Accumulator controls
• Bale shift arm automatic and manual Balers with
late production electronics also have a lockout
setting
Baler functions monitored
• Plunger load, bale chamber tension pressure,
bale counts – field (two on balers with late
production electronics) and total, flakes/bale,
driving meter, stuffer cycles, knotter and needle
performance, feeder performance, stuffer shear
bolt, gearbox over heating, automatic electronic
system performance checks Balers with late
production electronics also have a low voltage
check
Accumulator functions monitored
• Bales loaded, direction of next bale, operator alert
– manual mode, bale to be unloaded, and bale shift
bar malfunctions
Baler functions monitored
Bale weight (optional)
