Part No. 920525 Rev A - Wayne 3/VISTA series Service Manual

The Maintenance Mode is used to access the functions and statistics in the 3/Vista computer.
Service technicians can access the Maintenance Mode by using the Infrared Remote (IR) remote
control or by running the Service Terminal Program (STP) from a laptop computer. Both of these
methods and the descriptions of the functions and statistics are discussed in detail in this section.
6.1 IR REMOTE CONTROL
The Infrared Remote (IR) Control communicates with the pump
computer by an infrared link to the sensor mounted on the dispenser's
sales display board behind the bezel.
The IR remote control has 16 buttons. When the remote control is held
close to the infrared eye (Figure 6-2.) on the display board, it can be
used to access dispenser functions and statistics (diagnostics). The
remote is used to set unit prices, fueling point numbers, serial or stand-
alone communications, blend ratios, read electronic totalizers and error
codes, and perform many other diagnostic and service related tasks via
the Maintenance Mode.
Four levels of entry to the Maintenance Mode are listed below. To
access the mode, hold the remote control within 12" of the display and
press the appropriate key as follows:
for Field Service entry using field engineer password press
for Station Manager entry using station manager password press
for Operator entry using operator password press
for Weights and Measures entry using W&M password press
The maintenance mode asks for a password twice before allowing access to the maintenance
mode functions and statistics. A 10 second time-out is built into the password entry code.
When the word PASS 1 appears on the sales display, enter password and press ENTER. You
have 10 seconds to start entering the password. The timer restarts after you press a key.
PASS 2 appears on the sales display, prompting you to enter the same password again and
press ENTER. The unit price display will show "F - - ", the money display shows the software
version number, and the volume display shows the date of the software version. At this point,
you can go to either Functions or to Statistics. To edit or view functions, enter the function
number and press ENTER. The function number will appear in the unit price display. To
enter the statistics viewing mode press either the UP or DOWN arrow when the unit price is
displaying "F - - ". When you enter the statistics viewing mode, the unit price display window
shows "S - - ", the money display window shows the current transaction count for side A, and
