BZ1-G - Speed relay

Application
Speed supervision of signets


Function
Via the output frequency of the generator, the BZ1 detects the speed of the genset to be supervised. The relay is provided with three independently
adjustable elements for ignition speed, under- and overspeed.
The rated frequency can be changed from 50 Hz (left stop) to 60 Hz (right stop) by means of potentiometer CAL. At CAL-A2 a current of 0 - 20 mA in prportion
to the speed is available for indication of speed.

The unit BZ1 is designed to be fastened onto a DIN-rail acc. to DIN EN 50022 same as all units of the BASIC LINE.
The front plate of the unit is protected with a sealable transparent cover (IP40).
Please remove the transparent cover with a screw driver to adjust the relay.


LEDs
The LED fZ lights up at ignition speed. The LED f< extinguishes at underspeed. During operation without fault LEDs fZ and f< light up.
The LED f> lights up at over-speed.


Auxiliary Voltage Supply

The unit BZ1 needs a separate auxiliary voltage supply.The supply voltage will be connected to terminals A1 - A2.


Connecting Terminals
The connection up to a maximum of 2 x 2.5 mm cross-section conductors is possible. For this procedure the transparent cover of the unit has be removed.

Setting Ranges

fZ      : 10 - 50 % fn
f<      : 60 - 100 % fn
f>      : 90 - 130 % fn
fn (CAL) : 50/60 Hz
