Configuration of the APM
Digital Input Configuration
There are two (2) discrete digital inputs located on the rear of the APM (see Appendix B for more details).
These inputs are designed to be activated with a dry contact closure between the digital input and the
common terminal. The digital inputs are configurable to provide either an external alarm message on the
APM display, or to set the APM into unoccupied
or “night setback” mode.
Appendix H gives a list of all available messages that can be displayed on the APM as a result of a
closed or open contact (configurable) on either digital input.
Selection 1
: Under the configuration menu, select
DIGITAL INPUTS
see
[SCREEN1C]
.
Selection 2
: Select Digital Input to Configure
[SCREEN 2C]
.
Both digital inputs are configured in the same way, with the same options available for each. To keep
things simple, digital input 1 will be demonstrated, with the same steps being available for digital input 2.
Press
DIGITAL INPUT 1
to select it for configuration.
Selection 3
: External Input or Unoccupied Input Selection
[SCREEN 3C].
To configure the digital input to accept an external switch contact to indicate an external alarm situation,
press the
EXTERNAL ALARM INPUT
button. By pressing the
UNOCCUPIED INPUT
selection, the APM
will interpret a switch contact to indicate unoccupied mode and thus cause the APM to change its internal
settings for unoccupied mode.
Note: if the
UNOCCUPIED INPUT
is being used, please skip to
selection 5
.
Selection 3a
: After selecting external alarm input, the APM will ask for information on the status of the
digital input and what to associate it with
[SCREEN 4C]
. Select
OPEN=NORMAL CLOSE=ALARM
if a
normally open switch contact will be used to drive the input; thus a closed contact between digital input 1
and common will cause the APM to display an external alarm message and go into alarm mode. Select
CLOSE=NORMAL OPEN=ALARM
if a normally closed switch contact will be used to drive the input (an
open contact between digital input 1 and common will cause the APM to display an external alarm
message and go into alarm mode.
Selection 3b
: Displaying an External Alarm Message
[SCREEN 7C]
The APM offers fourteen different messages that can be displayed on the APM during an alarm condition.
Appendix H lists all available messages; however, if a message is not necessary, simply pressing the
disable button will disable this function. The APM
simply displays “WARNING” if disabled is chosen.
Selection 3c
: External Alarm Delay
[SCREEN 8C]
If an external alarm message is selected from the list, the next screen displayed on the APM is the delay
time entry screen. By using the plus and minus buttons [
or
] the time delay, in seconds, can be
increased or decreased as desired. Press
ACCEPT
when completed. Note: a value of 0 turns off the
delay completely.
Selection 4
: Exiting the External Alarm Configuration Menu
When complete, press the
EXIT
button to go back to the
DIGITAL INPUTS
configuration options screen.
Press the
EXIT
button once again to go back to the
CONFIGURATION MENU
screen.
Selection 5
: Unoccupied Input State
By choosing the unoccupied mode for the digital input, the APM will prompt for the proper digital input
states for the unoccupied mode
[SCREEN 5C]
. Select
OPEN=OCCUPIED CLOSE=UNOCCUPIED
if a
normally open switch contact will be used to drive the input; thus a closed contact between digital input 1
and common will cause the APM to reset the set points to the unoccupied values. The APM will also
display a message informing the operator the APM is in unoccupied mode. Select
CLOSE=OCCUPIED
OPEN=UNOCCUPIED
if a normally closed switch contact will be used to drive the input (an open contact
between digital input 1 and common will cause the APM to reset the set points to the unoccupied values.
