Change of bridge
A change of bridge can be carried out in two different modes:
− Range comparison
− Position comparison

If the accelerator of the passive command initiator is in the incorrect range (reverse at
passive bridge if forward or neutral is set at active bridge, or forward at passive bridge if
reverse or neutral is set at active bridge) the buzzer beeps slowly and the command
lamps flash slowly. If the accelerator of the passive bridge is in the correct range (forward
or neutral at passive bridge if forward is set at active bridge, or reverse or neutral at
passive bridge if reverse is set at active bridge) the buzzer beeps quickly and the com-
mand lamps flash quickly. Command is assumed if the button is pressed again.
Position comparison mode
In the position comparison mode the accelerator position of the active command initiator
must not diverge by more than 30 % from that of the active command initiator. In addition
the range too (forward, neutral, reverse) must be the same before a change of bridge
can be effected. The button does not have to be pressed a second time. The change is
made directly as soon as the accelerator position is correct.
This gives the operator the possibility of moving the accelerator once he has pressed the
button until he has found the right range and the change of bridge proceeds automati-
cally. If the correct range is not found within 30 seconds the change of bridge is aborted.
Danger:
Classification regulations state that the current drive command must not be al-
tered by a change of bridge. For this reason choose the position comparison
mode in the case of ships with a class.
Note on twin engines: In the case of a command initiator with 2 accelerators both accel-
erators must be in the correct position before a change of bridge can be effected. The
function of the command lamp is allocated to the relevant accelerator. The buzzer does
not start to beep quickly until both accelerator positions are correct.
