Installation and Operation
Link WTS – Link 150 M3 MCU
Connect Power
1. Connect the power plug from the AC adapter to the jack labeled
PWR
on the
MCU.
Use only the provided Class II AC Adapter with output 24VDC, 1A.
For installations with more than one MCU, use an outlet strip with a
built-in power switch. This allows the MCUs to be turned on and off
together.
2. Plug the AC adapter into a 110VAC outlet or switch on the outlet strip to apply
power to the MCU.
Set Switch Interface Type
The following steps explain how to assign a switch interface type to the MCU. This
procedure must be done in on each MCU.
1. Power on the MCU with the mode switch in the
NORMAL
position.
Because the MCU does not have a switch type assigned, it will alarm (the
ERROR
LED will flash along with
STATUS
LEDs
1
,
2
,
3
,
4
, and
5
). This should take less
than 2 minutes.
2. Power off the MCU.
3. Move the mode switch to
ADMIN
and power on the MCU. Within 15 seconds,
STATUS
LEDs
2
and
4
will light.
4. Press the
STEP
button three times.
STATUS
LEDs
1
,
2
, and
4
must be lit.
LINE
LEDs
1
through
8
(indicating an
unconfigured MCU) should also be lit.
If any other combination of
LINE
LEDs is lit, then a switch type has already been
selected. Go to step 5 to pick the desired switch type.
5. Press the
DEL/ENTER
button to select the correct switch interface type. With each
press of the
DEL/ENTER
button, a different series of
LINE
LEDs will be lit.
Continue to press
DEL/ENTER
until the correct
LINE
LEDs are lit. Use the
following list to select the desired switch interface.
