13 TROUBLE SHOOTING
The T-Max® Series has been designed for years of trouble free service. However, if a problem does arise, please follow the
following trouble shooting steps before calling technical support.
13.1 Trouble Shooting.
1) No Lights Illuminated on the T-Max® Mgr/Pro
Make sure that the transformer in plugged into the wall and into the power input on the T-Max® Mgr/Pro. Try plugging
the T-Max® Mgr/Pro into a different outlet. If you are using a surge suppresser or UPS backup system, try plugging the T-
Max® Mgr/Pro directly into the wall outlet. Check the circuit breaker in your building to make sure it’s on. Use a
voltmeter to measure the voltage on the transformer on the end which connects to the T-Max® Mgr/Pro.
2) The T-Max® Mgr/Pro does not show any beds, and the VFD display shows nothing.
This is an indication the program loaded in the T-Max® Mgr/Pro is lost or has been corrupted. From the C:\> prompt, type
the following: ADNET C1. Once the ADNET Utility program is on your computer screen, press L. Then press Y. After
you load the program back into the T-Max® Mgr/Pro, you may have to reset settings like the delay, max. beds number and
Auto Start. Refer to Section 6.5.11.
3) The T-Max® Mgr/Pro does not see any beds.
Go through the Quick installation setup in Section 2. Cycle power on the T-Max® Mgr/Pro. The T-Max® Mgr/Pro will
rescan the network. Make sure each T-Max® 3A has a unique address. Swap the modular cable between the T-Max®
Mgr/Pro and the T-Max® 3A is connected to.
4) When going through the Quick Installation set-up, when I press 888 then Enter on the T-Max® Mgr/Pro to set
the addresses, some or all of the T-Max® 3As do not go to 99 and buzz.
Check the cable between the T-Max® Mgr/Pro and the first T-Max® 3A. Swap the T-Max® 3A in the first room with the
last one.
5) When power is applied to the T-Max® Mgr/Pro, bed 1-5 show on the T-Max® Mgr/Pro, but the rest of my beds
do not show.
Go through the Quick Installation in Section 2. Make sure that power is applied and modular cables are connected to each
T-Max® 3A. Try a new modular cable between the last T-Max® 3A displayed and the first T-Max® 3A that does not
show on the T-Max® Mgr/Pro in the daisy chain. If you don’t
have a spare cable, swap the cable between the last T-Max®
3A that appears on the T-Max® Mgr/Pro and the first T-Max® 3A that does not appear on the T-Max® Mgr/Pro with a
modular cable that is connected between two T-Max® 3As that appear on the T-Max® Mgr/Pro display. If the problem
follows, the modular cable is either bad or wired incorrectly. Check the modular cable pinouts on the defective cable (refer
to Section 12.9, Figure I). If the problem does not follow, swap the first T-Max® 3A that does not appear on the T-Max®
Mgr/Pro in the daisy chain with one that does. If the problem follows, return the defective T-Max® 3A for repair. If the
problem does not follow, swap the last T-Max® 3A that appears on the T-Max® Mgr/Pro with one of the other T-Max®
3As that appears on the T-Max® Mgr/Pro.
5) When running ADNET, the computer beeps, the screen reads communication error.
This means that ADNET.EXE cannot locate the T-Max® Mgr/Pro. Make sure the serial cable is connected to the
computer and the T-Max® Mgr/Pro. Make sure there is power to the T-Max® Mgr/Pro. If it still does not work, determine
which serial port the T-Max® Mgr/Pro is connected to. This will be in the computer’s literature. If you cannot determine
which port you are connected to, type the following: ADNET C2 <Enter>, then ADNET C3 <Enter>, then ADNET C4.
<press the Enter key>. If you see the Screen shown in Section 6.1, the computer is communicating with the T-Max®
Mgr/Pro. If none of these command lines work, try another serial port cable. Try another serial port on the computer (most
computers come with two serial ports).
6) After running Rescan in ADNET, the screen does not show the beds added or subtracted.
Press V. A window will appear displaying the software versions. Press Enter and the window will disappear showing the
ADNET screen with the correct configuration.
