9820K Setup and Special Features
Pulser Output Rate Switches
When the 9820K is connected to Gasboy Controllers using Pulse-Output mode or any
non-Gasboy fuel management system (standalone), the pulser signals are sent out via the
Pump I/F PCB. The pulse rate required by the monitoring equipment can be configured by
setting the switches as shown in the chart below. Pulse-out rate represents the pulses per unit
(gallon, liter, or imperial gallon). For domestic units, the pulse rate can be up to 500 PPG. For
international units, the pulse rate can be up to 100 PPL. This switch may need to be sealed by
a Weights and Measures paper seal if the 9820K is used for the resale of product.
Note: If a valid pulse-out rate is not selected, the CPU will not output pulses.
Leading zeros are always suppressed in the hundreds and tens positions to the left of the
decimal point. When in standalone mode, positions to the right of the decimal point are
displayed based on the pulse rate selected as shown in the chart below.
Timeout Switch (if JP2 is Installed)
When the 9820K is in standalone mode, it will turn off an active hose if it does not detect
pulses for 4 minutes, 15 seconds. This timeout feature can be disabled by setting switch
SW2-4 to Open.

9820K Dual Pulse Output Option
When the 9820K is using the Pump I/F PCB (M06587A001) to create output pulses to
monitoring equipment, it can be configured for one or two isolated pulse outputs. For example,
use two isolated outputs to send pulses to a fuel management system and tank monitoring
equipment. To set the pulse output for a single output, set jumpers JP1 and JP2 on the Pump I/
F PCB to position 1 and use the standard wiring shown in
on
or
. To set the pulse output for two isolated pulse outputs, set JP1 and JP2 to position 2
and use the wiring diagram shown in
. JP3 should remain open in both
cases.
