CPU SWITCH SETTINGS
The 9820A can be configured for
various operating conditions using the
switches located on the CPU PCB.
Check these switches and change
their settings if necessary. Switch
settings should be changed with the
power switch OFF. The new settings
are read by the CPU PCB when the
power is turned ON again.
SW1
SW1-1 Baud Rate
This switch is set to reflect the communication rate
of the GASBOY RS-485 pump loop; open for 9600
baud or closed for 1200 baud. The GASBOY CFN
system and TopKAT communicate at 9600 baud.
SW1-2 Mode
If the 9820 is controlled by a GASBOY
CFN or TopKAT electronic fuel
management system, the switch should
be open (on-line mode). If the 9820 is
controlled by a GASBOY Series 1000 or
TopKAT mechanical system, or
controlled by any non-GASBOY system,
or not controlled by any fuel
management system at all, the switch
should be closed (standalone mode).
NOTE: The 9820 is shipped in standalone mode.
SW1-3, SW1-4 Delay Time
These two switches set the delay time used by leak detectors in
submersible pump applications. The delay time is the period
between activation of the submersible pump and activation of the
slow flow valve. This time should be set according to the type of
leak detector installed on the submersible pump to allow a normal
leak test for each transaction. The delay time should be set to
zero seconds for suction pumps.
SW1-5
Not used.
