Specification E (Kensho K45)

Constant Pressure system
The Spec E control system is designed to automatically start & stop the engine by closure of a volt free contact. Once the engine has started & warmed up the control system will automatically adjust the engine speed to maintain a constant pump discharge pressure. The rate of speed change & dead band parameters are adjustable to reduce the effects of water hammer & pressure surges in the irrigation system. The control system incorporates low oil pressure, high engine temperature, low coolant level & pump discharge high & low pressure protection. The pump pressure sender is supplied loose with the control system.
