Panel Set-up Information.
Master - Slave Conguration.
All panels are supplied congured as master panels.
In the event that more than one panel is being used to control
one engine then there is the choice of making one of them a
slave to the other (master) panel. Where there is one panel in
the wheelhouse and another on the ybridge then there is the
option of making the control functions on the ybridge panel
(slave) only operational when the wheelhouse panel (master)
is switched on.
The illustration below shows the removable link on the rear of
the panel. To convert a panel to slave remove the link from the
master (M) terminal and ret to the slave (S) terminal.
Note that one panel must always be a master and that no more
than two panels should be connected to one engine without
reference to Sabre Engines Ltd.
Tachometer Set-up Procedure.
All panels are supplied set to match their associated engine.
In the event that the tachometer needs re calibrating the
following procedure should be followed.
a) Ensure that the panel is connected to it’s interconnecting
lead leading back to the engine.
b) Insert a probe into the rear of the tachometer as shown in
the drawing below. Lightly press the set-up switch within the
hole and at the same time switch ON the panel.
c) Keeping the set-up switch held down observe the LCD
display on the front of the tachometer. When the word PULSE
is displayed release the set-up switch.
d) A number will now be visible and individual digits will start
to ash. The ashing digit can be adjusted by depressing the
operating set-up switch to index the number to the required
value. Repeat this for all digits as required.
e) When complete await for the display to revert back to
engine hours.
f) Switch panel to OFF.
Note to establish the correct setting for the tachourmeter the
following formula should be applied.
Diameter of Alternator Driven Pulley
X 6 = Number of Pulses.
