Testing Alarm Out Status
Alarm outputs that have been disabled will deactivate
the alarm output contact located on TB1, terminals #17
and #18,
refer to the Wiring Control Document on page
116 in Appendix D . You may test the alarm output in
general by choosing the Alarm SwitchTest option
below, figure 164-165, or you may choose to
Simulate specific alarms as illustrated in this section
as well.
Choose *Set in the main menu, figure 159.
Choose *Par – parameters in the Set Selection menu,
figure 160.
Choose *Flow or *Time in the Set Parameters menu,
figure 161.
Choose *Alarm from the Proportional-to-Time or Flow
menus, figure 162.
Choose *Test from the Alarm Out Status menu,
figure 163.
Choose *SW in the Switch / Simulation menu, figures 164.
To activate the Alarm Test Switch, figures 165, press
and release the Select key. The entered value will flash
when it is chosen. Use the Down Arrow or Up Arrow
keys to change the setting. ON / Relay Open indicates
the alarm relay is in the test mode. OFF / Relay Closed
indicates the relay is in the normal mode. Press the
Enter key to load the entry into memory. When the unit
is in the Alarm Test Mode, a bright red light will flash in
the alarm light indicator located just below the SELECT /
ENTER switch. The display will stop flashing when the
entered value is loaded into the memory. Press the Up
Arrow key to advance to return to the Switch / Simula-
tion menu.

an alarm is simulated or real, a bright red light will flash
in the alarm light indicator located just below the SE-
LECT / ENTER switch. Any time a Non-Alarm is simu-
lated or real, a bright green light will flash in the
indicator light indicator located just below the Down Arrow key.
