Vansco Electronic Monitor Technical Specifications
Fan RPM Fan RPM is displayed when the selector switch is set to FAN.
The RPM range is 0-9990 RPM with a resolution of 10 RPM.
The fan RPM is continuously monitored for alarm purposes.
The alarm trips when the fan speed falls below the user variable low alarm set point or goes above
the user variable high alarm set point
The factory programmed low alarm point is 3000 RPM. The user adjustable range is between 0 and
the high set point. Low alarm point should be set at 2000 RPM.
The factory programmed high alarm point is 6500 RPM. The user adjustable range is between 0 and
9900 RPM. Reset the high alarm point at 5000 RPM.
The factory programmed pulses per revolution is 1. Reset pulses per revolution to 3.
Response time to an alarm condition is 1 second maximum.
Shaft RPM Two shaft speeds, Front and Rear are monitored. Shaft speeds are displayed when the rotary switch is set
to the appropriate position.
The operator may disable unwanted shaft inputs.
The input signal is from a reed switch.
All shaft speeds are continuously monitored for alarm purposes.
An alarm will be generated whenever there is more than 15 seconds between reed switch hits.
Shaft alarm generation will be delayed by 30 seconds if ground speed is below 2 MPH. This delay is
intended to reduce nuisance alarms when turning on headlands.
The monitors are factory programmed with the bins and shafts disabled.
Set both shafts for 2 pulses per revolution.
Bin Level Indication Two bin levels are monitored; Front and Rear
The bins are pressurized to 20" - 30" H
