Compaq MTEK6000 user manual Open Door Alarm optional, Software Error Alarm, Memory History Logging

MTEK6000 SERIES USER'S MANUAL

Open Door Alarm (optional)

The Open Door (tamper) alarm is initiated when the door of the MTEK6000 opens. When this occurs, a full wake-up is triggered and the MTEK6000 executes its processes. The alarm is inactive when the door is closed.

Software Error Alarm

If there is a fault in the software, the Software Error alarm will initiate.

MEMORY (HISTORY LOGGING)

The MTEK6000 has a total of 96K (Main 64K bank and Auxiliary 32K bank) of RAM for database, audit trail, and history logging. With the large memory capacity, over 81,000 bytes of non-volatile memory is reserved for storing historical meter data. The non-editable history file provides the user with time-related data logged in any variation of selectable intervals: minute, daily, weekly, and monthly. An event- driven history mode allows data logging when an event occurs (e.g., alarms). An experienced user with software can define the type of data and collection period. Since history data elements are stored in a memory block, the size has to be assigned at the time the history process is created in the device, typically when the database is downloaded at the factory.

NOTE

The size of the block CANNOT be changed once the history process has been created in the unit. A complete download would be required to reset the database and change the device's memory assignment.

The total number of records (entries) the device can log depends on the number of items you wish to log:

January 2002

# of Record =	81,000	.
	4 x (# of items to log +1)

NOTE

Since there are two individual data banks, you may not be able to access all of the memory. The configuration must be optimized to utilize most or all of the memory.

Data may be collected over the telephone lines via the modem, on-site through the enclosure side connector (RS-232C serial port), and/or optionally through the optical port (software required for collection). The collected data can then be used for:

1.Billing information

2.Measurement reports for utility and customer management.

3.System analysis using flow rate and pressure.

4.Support for estimating gas volume consumption in cases of meter or instrument malfunction.
