Before you start testing your equipment…
The CT3 Vending Tester PRO is a highly sophisticated piece of equip-
ment. Before applying power to a unit for testing, check the following
point:
Test with an ohmmeter for potential short circuit. Even
though the CT3 has a built-in protection, repeated hook-up of short
changers may result in damages to the CT3. Also, make sure you do
not press on the 117-volt button when you are in fact testing a 24-volt
coin changer. Pressing the 117-volt button sends that voltage to all
sockets.
Firmware version 1.5 now has a protection against acciden-
tal handling on the 117-volt button. You now have to press and hold
the 117-volt button for at least two seconds before the CT3 actually
sends that voltage to the sockets.
Look for the identification label on the side of the coin changer and bill
validator for the proper voltage to apply. Some MDB coin changers
will mention 34 volts as their operating voltage. Using the 24-volt sup-
ply on the CT3 will be sufficient to power up any MDB devices ade-
quately.
You are now ready to test your equipment. In the following pages, you
will find different sections adapted for each type of equipment the CT3
can test.
Read them very carefully .
Remember that the CT3 will display all messages any given unit is nor-
mally sending to the Vending Machine Controller (a.k.a. VMC). Those
messages will be numerous in an MDB device while being inexistent in
a Single Price coin changer and pulse type bill validator.
