Brake confirmation
The brake confirmation function is optional. This function controls the operation of the
mechanical brake. If a pressure feedback is available from the mechanical brake then
this function can be used to detect the failure of the brake before starting the pump. If
the mechanical brake is defective, this function generates a fault and also forbids the
start command.
