To add an operator display to a Tracer MP581 or
Tracer AH541 controller or a BMTX model building
control unit (BCU), remove the enclosure door, then
install the new door with the operator display. Keep
this document at or near the controller for access to
calibration and cleaning instructions for the
operator display.
Removing the door
To remove the enclosure door:
1. Open the door to a 90° angle from the enclosure
as shown in Figure 1 on page 2.
2. Lift the door to pull the hinge pegs from the
hinge holes.
Installing the door
To install the enclosure door:
1. Unpack the door and check for missing or dam-
aged parts. Check to make sure that the touch
screen and magnetic latches are installed. Check
for cracks in the plastic.
2. Hold the door at a 90° angle from the enclosure
as shown in Figure 1 on page 2.
3. Align the hinge pegs on the door with the hinge
holes on the enclosure.
4. Gently lower the door until it rests securely in
the hinge holes.
5. Verify that the door swings freely on the hinges
and that the magnetic latches hold the door
securely when it is closed.
6. Connect the operator-display cable to the opera-
tor display and the main board (Figure 1 on
page 2).
Note: The operator-display cable passes beneath
the termination board on enclosures with
factory-installed operator displays.
7. Secure the operator-display cable to the enclo-
sure with a wire tie.
Setting up the operator display
This section shows how to calibrate the operator-
display touch screen and how to adjust the

display screens and security, see the Tracer MP580/
581 Programmable Controller Programming guide
(CNT-SVP01B-EN), the Tracer AH540/541
Configurable Air-Handler Controller Setup and
Operations guide (CNT-SVX05B-EN), or the Tracer
Summit System Programming guide (BMTX-
SVP01A-EN).
