4.2.5 Set the Pulse Output Resolution (Pulse output interface option only)
Always be sure to verify the unit is properly cabled for pulse output operation. Certain
models must be cabled either for standalone OR pulse output mode. If the unit is to be
used in pulse output mode, the cable connection(s) from the Pulse Output board (J3A or
J3B) to the Sales Display J5 must be in place. See Appendix F for additional information
and Appendix K for Pulse Output cabling information.
The pulse ratio is configurable in the dispenser configuration. The factory default setting
is 100 pulses per gallon (100:1). Other available pulse ratios are shown in Section
4.2.5.1.
Reference Section 4.2.5.1 to make sure that the desired pulse ratio is available for your
model. Verify that the desired pulse ratio, and its corresponding pulse width for your
model (see Section 4.2.5.2), are compatible with the fuel control or monitoring system.
Section 4.2.5.3 explains how to change the pulse ratio in the dispenser configuration.
4.2.5.1 Pulse Ratios
4.2.5.2 Pulse Width (seconds)
The pulse width time represents the “on” time for the pulse output. The total pulse cycle
time (on and off time) will typically be at least twice the “on” time shown.
*NOTE: Enhanced capacity models can be identified by a “0” in the second position after the
“7” in the model number (e.g. 3/G7107D). Super-high capacity modes have a “2” in this
position (e.g. 3/G7127D).
