GASKET 4L7890 - Caterpillar

Note: If you install a Dry Contact I/O Accessory at your UPS Network Management Card (NMC), the "Environment" tab displays two top menu bar options, "Universal I/O" and "Environment". Except where noted, the settings described in this chapter are available for both options.Overview Page
The "Overview" page lists the status of environmental monitoring devices associated with the Network Management Card With Modbus Monitoring.
Table 1
Heading     Displayed Information    
Temperature and Humidity     Lists all sensors and, for each sensor, the alarm status, temperature currently recorded, and humidity (if supported) currently recorded. For detailed status or to reconfigure a parameter for a sensor, click the name of the sensor.    
Recent Environmental Events     The "Recent Environmental Events" field lists, in reverse chronological order, the most recent environmental events. To view the entire event log, click "More Events" at the lower right.    Temperature and Humidity Page
Brief Status
Click "Temp & Humidity" on the left navigation menu to display the name, alarm status, temperature, and humidity (if supported) for each sensor.Detailed Status And Configuration

Table 2
Parameter    Description    
Name     A name for this sensor. Maximum: 20 characters.    
Location     This physical location of the sensor. Maximum: 20 characters.    
Alarm Status     One of the following is displayed:
"Normal" if this sensor is not reporting an alarm condition.
If this sensor is in an alarm state, the text of the alarm, indicating which threshold is violated, and the severity of the alarm, indicated by color (red for critical, orange for warning).    
Thresholds     See the next two sections for descriptions of the configurable thresholds and "Hysteresis" values.    Thresholds
For each sensor, you set the same types of thresholds for temperature and (if supported) humidity measured at the sensor.
Table 3
Threshold    Description    
Maximum     If the threshold for maximum temperature or for maximum humidity for the sensor is exceeded, an alarm occurs.    
High     If the threshold for high temperature or for high humidity for the sensor is exceeded, an alarm occurs.    
Low     If the temperature or humidity drops below the low threshold for the sensor, an alarm occurs.    
Minimum     If the temperature or humidity drops below the minimum threshold for the sensor, an alarm occurs.    Hysteresis
This value specifies how far past a threshold the temperature or humidity must return to clear a threshold violation
For Maximum and High threshold violations, the clearing point is the threshold minus the hysteresis.
For Minimum and Low threshold violations, the clearing point is the threshold plus the hysteresis.Increase the value for Temperature Hysteresis or Humidity Hysteresis to avoid multiple alarms if temperature or humidity that has caused a violation then wavers slightly up and down. If the hysteresis value is too low, such wavering can cause and clear a threshold violation repeatedly.Example of falling but wavering temperature - The minimum temperature threshold is 12° C (53.60° F), and the temperature
