5.4.4: Dial-O O ut Function
The Dial-Out Function (INP2) is intended to allow the meter to automatically report certain
conditions without user intervention. The modem is normally polling the meter to determine if any
abnormal or reportable conditions exist. The modem checks the following meter conditions and
programmed events (set in Communicator EXT) to determine if a call should be placed.
•
Are any meter set-point limits exceeded?
•
Has status of high-speed inputs changed?
•
Has waveform been recorded?
•
Has power quality event been recorded?
•
Has a control output changed?
•
Has meter experienced a loss of control power?
•
Is either history log approaching a full condition?
•
Is the event log approaching a full condition?
•
Is any other log approaching a full condition?
•
Has the modem password failed?
•
Has communication with the meter failed?
If any of the monitored events exist, the modem will automatically initiate a call to a specified
location to make a report or perform some other function. For log full conditions, the meter will
automatically download the log(s) that are nearing the full state. The modem can be programmed to
call two different numbers to make the required reports, Primary and Backup.
The modem can be programmed with an ASCII string for identification purposes. If this string in
present the modem will play the string to the host computer upon connection to identify the meter to
the host software. Refer to the Communicator EXT User Manual for programming details.
The modem includes a connection for an external 3V Lithium Battery (with custom leads and velcro
mounting) to power the modem if the meter loses control power. Using the battery, the modem will
be able to complete a reporting call even if power to the meter has been disconnected. This feature
allows the meter to report power outage conditions. Under normal conditions, the battery should
provide in excess of 10 years of service during storage conditions (disconnected from terminals) or
when properly installed in an energized meter. The battery should provide more than one year of
service during outage conditions (on battery backup). A LOW BATTERY indicator will appear on
the display screen (ONLY when there is a low battery). Call the factory for a replacement battery.
Replacement of the battery is simple. The battery is attached to a cable (if ordered) which
pigtails from the back of the meter with a connector (see NOTE below and Fig. 6.2 and Table 6.1).
Installation steps:
1. Remove the old battery by disconnecting it at the connector.
2. Install the new battery by snapping it into the connector.
3. Peel and stick the velcro adhesive somewhere outside the meter (or use the old adhesive to fasten
the battery in place).
NOTE: Custom leads and Velcro mounting are not included in some earlier versions of the Switchboard
Meter. Call the factory for installation/replacement part BATT4384.
