Overspeed Interrupt, when enabled, allows for a two-stage process to prevent sweeping at excessive speeds by warning the operator at a set PIN-code protected configurable speed and then by activating ASI at a set configurable speed. From 5-20 mph the operator will receive a warning and at 8-25 mph the Auto Sweep Interrupt will engage depending on ranges set.
Reverse Trigger Bypass, when enabled, will prevent ASI from activating when the transmission is placed in reverse. This allows ASI to be activated using other triggers such as engaging the ASI RESET switch for one button start/stop sweeping.
RPM Return, when enabled, will allow ASI to return the blower RPM to the previous setting before ASI was activated.
Dump Switch In-cab is located on the control panel to activate dump operation from inside cab.
