CHAPTER 10: METER WITH INTERNAL MODEM OPTION (COMM OPTION 2) DIAL-OUT FUNCTION
EPM 9450/9650 ADVANCED POWER QUALITY METERING SYSTEM – INSTRUCTION MANUAL 10–3
10.4 Dial-Out Function
The Dial-Out Function enabled by Comm Option 2 allows the meter to automatically report
certain conditions without direct user oversight. The modem normally polls the meter to
determine if any abnormal or reportable conditions exist, such as those in the following
list. If such conditions are found, the modem checks meter conditions and events, which
have been programmed through GE Communicator, to determine if a call should be
placed.
• Are any meter set-point limits exceeded?
• Has the status of the High-Speed Inputs changed?
• Has a waveform been recorded?
• Has a power quality event been recorded?
• Has a control output changed?
• 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 EPM 9450/9650 meter failed?
If any of the monitored events exist, the modem automatically initiates a call to a specified
location to make a report or perform some other function. For log full conditions, the meter
automatically downloads 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 is present, the modem plays the string to the host computer upon connection to
identify the meter to the host software. Refer to the GE Communicator Instruction Manual
for programming details.
