Operation
general
information
Figure O-GI-13. Operator-display connector on the Tracer AH540/541
Connecting the portable
operator display
The portable operator display is designed
for temporary connections to Tracer
AH541 controllers. It can be hot swapped.
CAUTION
Avoid Equipment Damage!
To clean the operator display, use a
cloth dampened with commercial
liquid glass cleaner. Spraying water or
cleansers directly on the screen may
result in equipment damage.
IMPORTANT: The portable operator
display is not used for time clock schedul-
ing. To provide scheduling, you must use a
permanently-connected door mounted
operator display, stand-alone operator
display, or Tracer Summit system.
To connect the portable operator display:
1. Open the Tracer AH541 enclosure
door.
2. Attach the operator-display cable to
the operator-display connector on the
circuit board (see Figure O-GI-13).
The operator display receives power
from the Tracer AH541 and turns on
automatically when it is connected to the
controller. The operator display is hot-
swappable, so there is no need to power
down the controller.
Setting up the operator display
The home screen is the starting point for
navigating through the screens of the
operator display. The home screen is
displayed when the unit is idle. The screen
contains the following information from
top to bottom:
• Time and date
• The controller location label: When no
location is specified and the controller
is a Tracer AH540, “Tracer AH540” is
displayed. When no location is specified
and the controller is a Tracer AH541,
“Warning: Unit Config Required” is
displayed.
• Operating parameters of the controller
• Push buttons: Touch one of the five
buttons — View, Alarm, Schedule,
Override, or Setup — to access the
desired set of screens.
Note: The schedule button does not
appear on the Home screen when a
portable operator display is connected to
the controller because the portable
operator display does not have a time
clock and therefore cannot be used to set
up schedules.
