Overview Page
The "Overview" page lists the status of environmental monitoring devices associated with the Network Management Card With Modbus Monitoring.
| 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
Click the name of a sensor for detailed alarm status or to configure the values:
Identification And Alarm Status
| 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.
| 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 hysteresis is 2° C (35.60° F). The temperature drops below 12° C (53.60° F), violating the threshold and causing an alarm. The temperature then wavers up to 13° C (55.40° F) and then down to 11° C (51.80° F) repeatedly, but - because of the 2° C (35.60° F) hysteresis value - no clearing event and therefore no new violation or alarm occurs. For the existing violation to clear, the temperature would have to rise above 14° C (57.20° F) (more than 2° C (35.60° F) above the threshold).
Example of rising but wavering humidity - The maximum humidity threshold is 65 percent, and the humidity hysteresis is 10 percent. The humidity rises above 65 percent, violating the threshold. The humidity then wavers down to 60 percent and up to 70 percent repeatedly, but no clearing event and therefore no new violation occur. For the existing violation to clear, the humidity would have to drop below 55 percent (10 percent past the threshold).
Input Contacts Page
Brief Status
Click "Input Contacts" on the left navigation menu to display the name, alarm status, and state (open or closed) of each input contact.
Detailed Status And Configuration
Click the name of an input contact for detailed status or to configure the values:
| Parameter | Description |
|---|---|
| Input Contact | Enable or disable this input contact. When disabled, the contact generates no alarm even when the contact is in the abnormal position. |
| Name | A name for this input contact. Maximum: 20 characters. |
| Location | The location of this input contact. Maximum: 20 characters. |
| Alarm Status | "Normal" if this input contact is not reporting an alarm, or the severity of the alarm, if this input contact is reporting an alarm. |
| State | The current state of this input contact: "Closed" or "Open". |
| Normal State | The normal (non-alarm) state of this input contact: "Closed" or "Open". |
| Severity | The severity of the alarm that the abnormal state of this input contact generates: "Warning" or "Critical". |
Output Relay Page
This option is only available for devices with installed Dry Contact I/O Accessories. Select the "Environment" tab, then "Universal I/O" from the top menu bar. Click "Output Relay" to display the status of the output relay and configure the relays values.
| Parameter | Description |
|---|---|
| Name | A name for this output relay. Maximum: 20 characters. |
| Location | The location of this output relay. Maximum: 20 characters. |
| Alarm Status | "Normal" if this output relay is not reporting an alarm, or the severity of the alarm if this output relay is reporting an alarm. |
| State | The current state of this output relay: "Closed" or "Open". |
| Normal State | The normal (non-alarm) state of this output relay: "Closed" or "Open". |
| Control | To change the current state of this output relay, check-mark the setting. |
| Delay | The number of seconds a selected alarm condition must exist before the output relay is activated. Use this setting to avoid activating an alarm for brief transient conditions. NOTE: Even if additional mapped alarms occur after the delay begins, the delay does not restart but continues until the output relay is activated. |
| Hold | The minimum number of seconds the output relay remains activated after the alarm occurs. Even if the activating alarm condition is corrected, the output relay remains activated until this time period expires. |
About Page
Click "About" on the left navigation menu of the top menu bar option "Environment" to display what environmental monitoring devices are in use with this UPS and the device firmware versions.
Configuring the Control Policy
For a 375-3562 NMC with up to two connected Dry Contact I/O Accessories, you can configure the accessories outputs to respond to events. You can also configure the UPS and outputs to respond to input alarms.
Configuring An Output To Respond To An Event
- Select the "UPS" tab, "Control Policy" in the top menu bar, and by event under "Event Actions" on the left navigation menu.
- Click a category name to view all of the events in the category, or click a subcategory name to view the events in that subcategory.
- In the list of events, review the marked columns to see whether the required event is already configured to change the state of the output relay.
- To change the current configuration, click the event name, select the output relay that will change state when this event is detected, and click "Apply".
Configuring The UPS Or Output To Respond To An Input Alarm
- Select the "UPS" tab, "Control Policy" in the top menu bar, and by event under "Event Actions" on the left navigation menu.
- Click "I/O Contact", then click the name of the event to configure.
- The Management Card supports up to four inputs. Specify the input that will be associated with this event.
- In the "Port" drop-down list, select the Universal Sensor Port number (1 or 2) to which the Dry Contact I/O Accessory is installed.
- In the "Zone" drop-down list, select the zone letter (A or B) of the contact to which the input is installed.
- Define the action the UPS will perform when the input changes state, and select the output that will change state when this event is detected.
- Click "Display" to review your changes, then click "Apply".
Note: The action you configure occurs once. If you restore the input to the inputs normal state before the alarm condition clears, the output will not change state unless the alarm condition clears and then reoccurs.
