NOTES: (See  Sample Wiring Sche-
matic) 

1.  When using the Western Electronics model 

500 pulser, be sure to connect the hot side of 
the pulser power (BLACK WIRE) to the Clear 
Signal (C1 or C2). This insures that the pulser 
will begin at exactly zero and not part way 
through the first pulse. 

2.  If a manual reset mechanism is employed, a 

reset mimic switch must be installed for each 
dispenser (See Figure 3). This switch must be 
housed in an explosion-proof cover and simply 
connects the R1/R2 terminal lug with the corre-
sponding C1/C2 terminal lug. This is required 
so that customers can terminate a transaction 
once they are done fueling. In most cases, a 
customer depends on this switch since a typi-
cal sale involves overestimating the amount of 
fuel required. 

IMPORTANT NOTE: ALL WIRING MUST BE 
DONE IN ACCORDANCE WITH FEDERAL, 
STATE AND LOCAL CODES. 

The information contained in this guide is provided 
solely for planning purposes and so that appropri-
ate professional personnel can gain familiarity with 
QT Technologies products. QT Technologies 
makes no guarantee or warranty that any of the 
recommendations or guidelines contained herein 
are accurate or correct regarding Fire and Electri-
cal Codes. Compliance with local, state and federal 
codes are the responsibility of the owner/operator 
of the fuel delivery system.
