Description
The DC 9 is HEINZMANN’s digital
control for small and middle-sized
engines.
The highly efficient speed
governor is based on a fast
16-bit microprocessor. The DC 9 control unit works with one inductive pickup.
Additionally a Hall-type pickup is possible via multifunctional port.
DC 9 provides speed governor functions as well as positioner abilities. It is able
to drive direct working actuators. Gear-type actuators require the extension
module CU-01. The set point can be transmitted as a current, voltage or PWM
signal to the control unit. For configuration DC 9 uses HEINZMANN’s serial
interface for connection with DcDesk 2000.
Several error recognition, indication and reporting functions are provided. For
major alarm a separate output is applicable. The firmware allows configuration of
input/output allocation as well as activation and parameterisation of functions.
DC 9 control allows any mode of operation as running at fixed or variable speed.
In combination with HEINZMANN’s small and medium range actuators DC 9
provides an excellent solution for diesel or gas engines.
