aLarm oN reTUrN-To-NormaL
The Cell682 has the capability to notify you when an input (that had previously
gone into alarm) returns to normal. When checked, Alarm on Return-to-Normal
initiates this notification.
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 limits or in a fault con-
dition continuously 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.
analog inpUts
The 6 analog inputs can be programmed for 2.8K or 10K thermistor (temperature
in degrees Fahrenheit or Celsius) or 4–20mA transducer. The Cell682 will main-
tain the minimum and maximum values reached for each channel. When 4–20mA
is selected you can enter table low and high values to correlate the 4mA and 20mA
signals to actual values for your application. Click on the Analog Inputs Tab to dis-
play the main status screen.
Figure 3: Analog Inputs tab
This screen displays the current status of all 6 analog inputs. If any of the inputs
were in alarm the Alarm State column would display the word “Alarm.” If the
alarm was unacknowledged the Alarm State would say “Alarm Unack” and a but-
ton would appear at the bottom of the screen to acknowledge the alarm.
