Configuration of the APM
Relay Output Configuration
There are two (2) discrete relay outputs located on the rear of the APM (see Appendix B). These outputs
can be configured to react to either the purge button on the front panel or from an internal alarm
indication.
Selection 1
: To configure the outputs choose the
RELAY OUTPUTS
selection on the configuration menu
[SCREEN 1D]
. Both relay outputs are identical as far as configuration, thus only relay 1 will be
demonstrated.
Selection 2
: Select Relay Output to Configure
[SCREEN 2D]
.
First, select either
RELAY OUTPUT 1
or
RELAY OUTPUT 2
to configure. For this exercise, press the
RELAY OUTPUT 1
button.
Selection 3
: Alarm or Purge Selection
[SCREEN 3D].
Press the
ALARM
button to configure relay output 1 to respond to an internal alarm indication from the
APM. With this selection, relay output 1 will change states when an alarm is indicated on the APM.
Press the
PURGE
selection to configure relay output 1 to respond to the front
PURGE
button. With this
selection, relay output 1 will change states whenever the front
PURGE
button is pressed.
Selection 4
: Selecting Contact States
[SCREENS 4D & 5D]
After selecting either the purge or alarm selections, the APM will ask for information on the status of the
relay output contacts.
For the alarm function
[SCREEN 4D]
, select
NORMALLY OPEN CLOSE ON ALARM
if a normally open
switch contact is required to indicate no alarm, thus a closed contact between the two
RELAY 1
terminals
on the rear of the APM will occur whenever the APM goes into alarm. By selecting
NORMALLY CLOSED
OPEN ON ALARM
the contacts act in reverse; no alarm results in closed contacts between the two
RELAY
1
terminals on the rear of the APM, and an alarm indication on the APM causes the relay 1 contacts to
open.
For the purge function
[SCREEN 5D]
, select
NORMALLY OPEN CLOSE ON PURGE
if a normally open
switch contact is required to indicate the purge button has been pressed on the front of the APM. Thus a
closed contact between the two
RELAY 1
terminals on the rear of the APM will occur whenever the APM
goes into “purge” state. By selecting
NORMALLY CLOSED OPEN ON PURGE
the contacts act in
reverse; no purge results in closed contacts between the two
RELAY 1
terminals on the rear of the APM.
Thus a purge indication on the APM causes the relay 1 contacts to open.
Selection 5
: Exiting
[SCREEN 2D]
Simply press the
EXIT
button to return to the
CONFIGURATION MENU
selection.
Analog Output Configuration (OPTIONAL)
If the APM was ordered with an analog output, there will be a selection available in the
CONFIGURATION
MENU
to configure it, see
[SCREEN 1L]
. The analog output is a 0 to 10Vdc output that is fully configurable
to any flow desired. The calibration of the analog output is very easy, here’s how it’s done:
Selection 1
: Select Voltage Range
[SCREEN 2L]
.
After pressing the
ANALOG OUTPUT
selection on the main menu, press the
VOLTAGE RANGE
button
[SCREEN 2L]
to configure the voltage output.
Selection 2
: Configure Low Voltage Output Level
[SCREEN 3L]
The first item to configure is the required low voltage output from the APM. This is the lowest voltage the
APM will provide indicating a low face velocity. For example, if the desired voltage output is 1 to 5Vdc,
indicating 50 to 200FPM the value of 1Vdc would be entered using the plus and minus buttons [
and
].
Press the
ACCEPT
button when the required minimum output voltage is correctly displayed.
