SW1-6 Authorization
This switch allows activation of the 9820A from
some types of fuel management systems. When
the switch is closed, a 115 VAC (230 VAC Int’l)
signal must be present on the Control Feed line
for pump activation to occur (required setting for
Series 1000, TopKAT mechanical, and all non-
GASBOY systems ). When open, the 9800
ignores the Control Feed line (required setting for
CFN, TopKAT electronic, or no fuel system).
SW1-7 Totalizers
This switch should be set to open for normal operation. When closed,
this switch enables the reset of the electronic totalizers. See
View/Reset Totalizers later in this section for details.
SW1-8
Not used.
SW2
This four-position switch pack serves a dual purpose: as an address setting when communicating
on the GASBOY RS-485 loop or TopKAT, or as a pulser output rate selector when pulser data is
sent to a fuel management system other than a GASBOY CFN or TopKAT.
Address Switches
A unique address identifier must be set when the
9820A is connected to the GASBOY RS-485 pump
loop via the 9820A RS-485 I/F PCB. Because there
are 16 possible address combinations, up to 16 units
(single or twin) may be connected to the pump loop.
Addressing should start at 1 and continue
sequentially through 16. The physical wiring order
does not have to correspond with the address order;
that is the first unit on the RS-485 loop doesn't have
to be address 1. The chart at right gives the switch
settings and address selections.
