Handle Switch To Fleet System Signal - Bennett 3000 Series Service Manual

Handle Switch Signal - The handle signal to
the Fleet System comes from terminal strip
TS2. The handle signal is wired from the
Fleet System to this terminal strip. The pulse
output board provides a dry contact normally
open relay for both side 1 and side 2 handle
signals. These dry contact relays close when
it receives a signal from the CPU that the
fueling point handle is activated. When this
relay closes, it signals the Fleet System that
the fueling point is "in use".
signal can be an A.C. or D.C. voltage. This
voltage is provided by the Fleet System.
LED's - There is an LED above each relay on the
board. They are labeled D4 and D7. That LED is lit
when the Pulse Output board closes the normally
open relay. If you see that LED lit, that relay should
be closed.
There are 2 wires for each handle switch channel
and they are marked "side 1" and "side 2" (see
drawing). These wires connect to the Fleet system
handle input channel. Normally, the Fleet System
provides a D.C. voltage on these two wires (+12
volts is common). So, you should see this voltage
present at the channel on the Pulse Output board
when the handle is not activated.
Note - If a voltage is required by the Fleet System
for the handle signal, IT MUST BE PROVIDED BY
THE FLEET SYSTEM.
When the handle is lifted this relay closes, routing
this power through the relay back to the Fleet
System which indicates that the fueling point is "in
use".
Testing the Handle Switch Relay - To test the handle
switch relay, follow the procedure on the next page.
