SWT Troubleshooting
Overview
This section provides troubleshooting for the SWT Metreau keypads (DAS-MET-6SRC and DAS-MET-NUM).
Power Connections
Tracking down problems that are power related are somewhat easy because the unit either powers up or it doesn’t. If it does not,
there are several things to check.
1.
Check to make sure you are attached to a functioning live electrical circuit. If the branch circuit is dead check the breaker or
there may be a light switch controlling the power to the outlet. If it’s on a switched circuit try to obtain power elsewhere.
2.
Ensure that both ends of each power cord are firmly seated in all of the source components.
3.
If you’re plugged into power strips, check them for operation as well. Be aware these often have mini-breakers on them and
you should check to ensure that power is functioning in EACH outlet.
It is not uncommon for the inexpensive power strips to fail at one plug-in but not the others.
4.
There is a power switch located at the rear of the Controller, check to see that it is in the ON or (1) position.
5.
There is a fuse beside the power switch at the back of the Controller. Remove the fuse and inspect it to see that it is intact. If
you have an ohm meter, test for continuity across the fuse (sometimes they look good, but they’re really broken near one of
the ends). If you are using a power bar they often have mini-breakers on them, and you should check to ensure that all is well.
The fuse in the rear of the Unit is a
T8AL250v
.
Zone Connection Problems
If there is wall power and both the source components and the Controller seem to be powering up OK, but one or more of the
zones are not working, there may be a problem at the individual zone or with the cabling connecting to the zone. Begin by checking
each zone keypad for functionality by pressing the desired source button. The LED should light red next to the source on the KP-4e
keypads or should “wake up” with a screen menu on the touch panel keypad.
Dead Zones
There is power and the source devices and the Tango Controller seem to be powering up OK, but one or more of the zones are not
working.
Check each zones keypad for functionality by pressing the desired source button. The LED should light Red next to the source.
LED Does Not light
You are not getting power and command connectivity to the zone. Check other zones and select each source to determine if this is
specific to the source or the room in general. If the problem is in a particular room then there may be an issue with cabling to your
speakers or it may be the keypad itself. If you get similar results for a particular source in multiple zones then there may be an issue
with the source equipment and you should check to see that the selected source is ‘playing’. If every other zone is ok, check to
make sure cables to the speakers are secure and that you have tried to increase the volume level in the zone.
