aLarm eNaBLe/dIsaBLe
The Enable Alarms checkbox activates the alarm processing functions for the
selected channel. When the input exceeds the the programmed low or high alarm
limits and exceeds the programmed recognition time the notification process
begins.
aLarm oN reTUrN-To-NormaL
The Cell682 has the capability to notify you when an input (that had previously
gone into alarm) has returned to normal, that is, returns to within the pro-
grammed alarm limits. When checked, Alarm on Return-to-Normal initiates this
notification.
seTTING THe aLarm LImITs
Each analog input has a programmable Low and High Alarm limit. When the
input value goes beyond the programmed alarm limits for the duration of the
recognition time, the Cell682 will go into alarm and initiate the alarm notification
process.
Programmable range

aLarm reCoGNITIoN TIme
The Recognition Time is the time required for a fault condition to qualify as an
alarm event. The sensor/channel must remain beyond the programmed limits con-
tinuously for this entire period of time in order to become an alarm. The range of
values is 0–32,767 seconds.
aLarm reseT TIme
The Reset Time is the time allowed for an acknowledged alarm’s fault condition to
be corrected before the Cell682 resets (reactivates) the alarm and begins the mes-
sage delivery process all over again. The minimum reset time is 30 minutes, the
maximum is 32,767 minutes.
poWer INpUT
Power monitoring is a built-in function. The unit will go into alarm when the
power level drops below 11.75V for the programmed recognition time. In this
state the Power LED will blink.
