Ê How To View the Software Version
As MILNOR
®
makes improvements to the software which controls these machines, the software version num-
ber changes. This information is often very helpful in troubleshooting errors and malfunctions.
Ë Viewing Software Version During Power Up
—When power is first applied to the machine, the dis-
play will appear similar to FIGURE 1. This number is the software version; it will remain on the display for 80
seconds, then the normal operating display will appear.
Ë Viewing Software Version After Power Up
—The software version can also be viewed after the
power up sequence has finished provided the machine is not running a wash cycle.
1. Set the Attendant keyswitch to
“Attendant.”
2. Set the Run/Test keyswitch to
“Test.”
The software version will
remain on the display until the Test
button is pressed.
Ë How To Interpret the
Software Version
—The first
digit in the Deposit Coins display
represents the machine class. In the
case of 30015C4A and 30020C4A
models, this number is “2.” The
second digit in the Deposit Coins display is ignored for these models. The two digits in the Time Remaining display,
along with the single digit in the Machine Status display, make up the revision of the software.
NOTE: If the first digit in the Time Remaining display is an alphabetic character (A-Z), the software is
non-standard; therefore, the wash cycle may not be the same as that described in “OPERATION OF C4A
ELECTRONIC COIN WASHER-EXTRACTOR” (see Table of Contents).
Ê How To Exit the Testing Procedure
The machine may be returned to Automatic mode at any time during testing by switching the Run/Test and
Attendant keyswitches to “Run.”
