7.2.6.1
SETUP > ALARMS > SET ALARM PRIORITIES
This function enables you to assign one of three possible levels of importance to each type of system
alarm. The levels of importance, in ascending order of importance, are Information, Warning, and Critical.
Factory default settings are already assigned to each alarm message when you install the UPS. It may be,
however, that in your site a particular alarm condition is more or less important that the default value
assigned to the alarm. This function allows you to override the default value for a given alarm.
You can scroll through all of the possible alarm messages in the scroll box at the top of the window. The
assigned priority level for that alarm is highlighted. To modify the priority level, press the desired button.
It is also possible to instruct the system to ignore a specific alarm, by pressing the "Ignore" button near the
upper left corner of the screen.
7.2.6.2
SETUP > ALARMS > ALARM LIMITS
This function lets you set the threshold values for several important alarms.

VOLTAGE
LIMIT
Use this function to set the voltage levels at which the "AC VOLTAGE HIGH" and AC VOLTAGE LOW"
alarms will be activated.
You can also set a "hysteresis" value. This value damps the sensitivity of the alarms to prevent a situation
where, for example, a minor but frequent fluctuation of 1 Vac just above or below the threshold value
causes an ac voltage alarm to turn on and off many times, rapidly.
The hysteresis value is the number of volts that a measurement must change before an alarm senses that
the measurement has changed. So, in the example above, if you set a hysteresis value of 2, the alarm
state wouldn't change until the fluctuation grew to 2 Vac. This would reduce the number of alarms while still
ensuring that an alarm will be sounded when the voltage meets the threshold.

This function lets you set the temperature (in °C) at which the high-temperature alarm and low-temperature
alarm are generated. The temperature is read from an optional internal temperature sensor.
