Can you explain the settings on the RTU Configuration page?
To proceed with RTU Configuration, click on the RTU Config tab.
The following parameters applicable to the RTU are displayed above the horizontal line. Note: these parameters are informational only:
Watchdog Timer: This indicates how frequently the web site expects to receive periodic Template report transmissions from the RTU. If any such periodic report is missed, a Watchdog (missing scheduled report) alarm is created.
Account: This indicates whether the account is enabled at the RTU. Normally this should indicate Enabled. Channel
Suspension Timer: This indicates the period for which a channel is suspended before it is automatically re-enabled to send alarms. Suspension eliminates unwanted follow-on alarms due to dithering inputs, also describable as runaway alarms. If any given channel goes into alarm, then returns to normal, then goes into alarm again within the indicated Suspension Timer period, it will not be allowed to send additional alarms for the duration of the Suspension Timer period. This suspension time begins at the time of the initial alarm. If a channel becomes suspended due to a dithering input, a special suspension notification is sent to the same users who were eligible for notification for the alarm preceding the suspension, continuing until a notification is acknowledged. If you wish to clear the suspended status of an RTU channel before it would otherwise time out, temporarily disarm and then rearm the RTU, either from the web site or by visiting the RTU site.
Template Reports/Day: This indicates how frequently the RTU sends periodic scheduled Template Report transmissions. In some cases it relates to your Service Level.
Analog Reading Reports per Day: This indicates how many (if any) separate analog reading report transmissions will be sent by the RTU per day. All Application Templates provide alarms for exceeding high or low analog set points (assuming channel 9 or 10 are configured for analog).
- Application Templates 1 to 4 do not include actual analog readings in the Template (Pump) report. An optional separate Analog Reading Report provides analog readings (average, maximum, minimum and current reading as of time of report). This requires a corresponding Service Level.
- Application Templates 5 to7 provide limited versions of analog readings as part of their Template Reports. Therefore, in many cases with Application Templates 5 to 7, a separate Analog Reading Report is not required.

The following settable items appear below the horizontal line on the RTU Configuration page, and are changeable via RTU Command:
Armed state: This indicates whether the RTU was armed or disarmed as of the most recent transmission from the RTU. It also allows you to change the armed/disarmed state via an RTU Command. Note that when disarmed, the RTU will still send scheduled report transmissions. Only alarm transmissions are prevented.
Relay Output 1: This indicates the state of Relay Output 1 as of the most recent transmission from the RTU. It also allows you to change the state via an RTU Command (either momentary or maintained).
Relay Output 2: See Relay Output 1.
Relay Output Name: This allows you to enter a descriptive name for each Relay Output, so that in the future each output is identified in terms of its function. Channel alarm trip delay: This setting determines how long a channel input must continuously be in violation of its alarm criteria before the actual alarm is created. This same period applies to qualify for a Return to Normal.
Power failure trip delay: This setting determines how long primary power must be continuously off before a power failure alarm is created. RTU observes Daylight Savings Time: This setting determines whether the RTU automatically adjusts the time of its periodic scheduled reports to follow Daylight Savings Time. Note that this is distinct from the setting on the System Wide Settings page, which determines whether the times shown on the web site follow Daylight Savings Time.
Pump Performance alarm sensitivity: Occasionally a pump becomes partially or completely clogged or otherwise drops substantially in performance. When this occurs, the graphs on the Pump Report will make this apparent at a glance. However if such a drop in performance persists for several cycles as continuously analyzed by the RTU at all times, a special Pump Performance alarm will be created to notify users without waiting for the results to appear on the graphs. The sensitivity setting determines how severe and for how many cycles the performance drop must be in persist in order to generate such an alarm. Some pump stations will experience wide and rapid variations in inflow which can occasionally cause false alarms. In such cases the sensitivity setting should be adjusted accordingly.
Periodic report base time: This setting determines the time of day or night when the RTU sends its scheduled reports. If your service level provides for periodic reports two or four times per day, any new setting of the report base time will become the new starting point for such multiple reports per day.
