5.8 Pump 2 Speed (Liquid Tank Only)
The 3500VRC has two RPM inputs. Both of these inputs can be set up as either a Fan rpm input
(see 5.2 Fan RPM) or in the case of liquid a pump rpm input. The pump alarm warns the operator
when the pump rpm is outside the low and high set points. Two fan alarms are available. Enabling
the fan alarm displays live fan rpm on the main screen.
Pump alarms must be enabled before setting the pump low and high alarm points.
Note
Unlike Fan RPM, Pump RPM will NOT disengage drives when the Pump RPM falls below the low
alarm point. At any one time, only one Fan and one Pump, or two fans only, or two pumps
only can be used. (NOTE: Pump 2 reads in increments of 10rpm)
