CB212-1S, Handheld unit.
The functions of the handheld unit, CB212-1S, is controlled by electronic circuits at the printed circuit board
inside the housing. The handheld unit has two push buttons, one black and one red. The black is the deadmans
button, which can be operated by the lever or the directly to push the button.
The red button is the STOP button, intended for emergency stop of the fuelling process from a remote position.
The electronic has a failsafe design, telling that the system will stop if something goes wrong. That is
for instance if the cable short-circuits. This will immediately shut down the fuelling.
The wired deadman is normally delivered with a timer. When the handheld unit is operated, the fuelling process
is allowed to continue. But only for 2 minutes. Within this time, the operator has to release and re-operate the
handle quick, to make the fuelling continue.
If the handle is not reactivated, the fuelling will stop after the 2 minutes.
The last 30 seconds of the 2 minutes period, two output signals in the control unit can be used to warn the
operator, and tell him that he has to re-operate the handle in order to avoid stopping the fuelling process.
