PCXZ General Diagnostics
Due to the complex and hazardous nature of servicing dispensing control systems, you should
contact your POS dealer/distributer for technical support. They are responsible for first level of
support on their products.
Dispensers and other fuel handling equipment should always be installed and serviced by a
certified dispenser mechanic. This type of equipment is extremely hazardous if not handled
properly.
On the following pages are some typical oversights or problems which may prevent proper operation
with the PCXZ, regardless of the brand of dispenser/card reader. While dispensers vary drastically
from brand to brand and model to model, there are issues common to all dispensers. Before
proceeding to the troubleshooting steps for your particular brand of dispenser, go through this
checklist.

General Testing Procedures
T C HECK IT O UT !
T Are dispenser/reader IDs set properly? Most brand dispensers and their card readers must
have unique numbers — the dispenser/reader ID — set to identify each individual
dispenser/reader. A common problem occurs when the ID for a dispenser/reader is set the
same as for another dispenser/reader. Also, on new dispensers/readers, the manufacturer
usually sets IDs to a default value. If they are not changed, then all dispensers/readers will try
to answer at the same time, causing communications errors.
T Are cable connections secure? Check all cables from POS to dispensers/readers to ensure
that the connections are secure before applying power to any equipment. Crossed wiring for
both power and communications can cause erroneous operation as well as possible damage
to system components.
T Is the dispenser in manual override mode? Dispensers may be put in a manual override
mode to allow the dispenser to operate as if no control system is connected to it. The
dispenser in manual is capable of dispensing any time the handle is lifted off-hook. A
dispenser in manual mode will not operate correctly with a controller such as the PCXZ. For
operation with the PCXZ, be sure dispenser is in console control mode.
