CPU Switch Settings 9820K Setup and Special Features
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 0 seconds for suction pumps.

Note: Settings that are too short will result in the leak detector tripping incorrectly and the
ones that are too long will result in a longer wait for the fuel to be pumped.
SW1-5
Not used.
SW1-6: Authorization
This switch allows activation of the 9820K from some types of fuel management systems.
When the switch is closed, a 115 VAC (230 VAC International) 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 9820K ignores the Control Feed
line (required setting for CFN, TopKAT electronic, or no fuel system).
