The unit has a protection fuse located on the power supply
socket.
If this fuse must be replaced or changed because the power
supply is changed, use the time-lag fuse according to IEC 127/
2 with the values indicated on the table.
RESET: Display will show "0" when terminal E (RESET) is connected to terminal A (0 Vdc.) and will
remain
in "0" meanwhile terminals E and A remain connected.
CONTROL : This function is operative when terminal D (Channel 2) is connected to terminal A (0 Vdc.).
On model BDF-XX-T1, Channel 2 operates as INHIBIT control.
On model BDF-XX-T2, Channel 2 operates as UP/DOWN control.
0 Vdc.
The unit supplies the Excitation Voltage for sensors, through terminal B.
If the current required for the sensors or encoders installed is more than 100 mA then do not use this
