Entity EN0546 Instruction Manual

EN0546 is a device for the control of under and over voltage protection and for the visualization of the output voltage for alternators.
The ability to select the working voltage (230V three-phase, 230V single phase, 400V three-phase) EN0546 allows a wide range of applications.
The device has 3 LEDs and a button on the front, two trimmers and a switch on the back, and finally a trimmer positioned behind the front
panel.
The operation of the device in case of exceeding the maximum or minimum voltage limits must stop the supply voltage of the generator. This is
usually performed in two ways: by short-circuiting or interrupting the excitation of the alternator through a relay contact.
In the start-up phase, it is necessary to exclude the control dell'EN0546 pressing the button on the front panel to move from the stopped state of
the machine to a state of rotation.
The device notifies you via the 3-color LED's on the front if the output voltage of the generator is correct.
