Control Units
GU3320/GU3321 is a generation on single generating set intelligent controller which is in
shape and structure. It has improved the performance of the controller so that the product can
meet the needs of the user and Generator assembly plants for the different types of Automatic switch
control generation and protection needed.
GU3320 is an Auto Start controller.
GU3321 is an Automatic Mains Failure Controller. When running in "AUTO" mode, it detects the
Mains. It starts the generator automatically on Mains voltage failure. The Gen is on load; when Mains
resumes to normal, it stops the generator after the delay, Mains is on load.
Characteristics:
l The voltage and current using true RMS measuring.
l Multi-Language menu.
l 128 x 64 graphic .
l 3 Analogue inputs configurable with a variety of preset sensors and can also customize your own sensor curves.
l 6 Configurable relay outputs.
l 5 Configurable D- inputs.
l Buttons on control panel are used for selecting control modes, starting and stopping the
operating procedure, displaying data and modifying the parameters. LED indicators are used for indicating the operation mode of controller and the running status of Genset, and displays each measuring parameter and status.
l Standard RS485, the other optional RS232 or USB communication port, remote control, or to communicate with the PC, fully realized telesignalling, telemetry, remote control functions.
l All connections of the controller are by secure and socket, for ease and convenience to connect, move, maintain and replace the device. When secured by the screw locks it prevents the plugs from falling out by vibration etc.
