MTEK6000 SERIES USER'S MANUAL

Chapter 3 : Operating Modes

The MTEK6000 operates in any of five modes:

•Sleep

•Display

•Alarm

•Configuration (requires Virtual keypad, Meter Reader 4.10 or later, or pcGas Host software, or the optional external keypad and display)

•Calibration (requires Virtual keypad, Meter Reader 4.10 or later, software or the optional external keypad and display)

SLEEP/WAKE-UP MODE

In normal operation, the MTEK6000 maintains a powered-down state (sleep mode) to conserve battery life. In this state, the display will show the first label and the most recent value prior to the next wake-up interval. The unit will be updated depending upon the user's programmed wake-up interval. The default wake-up interval is 10 minutes. See Appendix A for a list of common MTEK6000 items including this parameter. Shorter intervals result in more frequent data; longer intervals provide for longer battery life. The scheduled wake- ups result in immediate power-down after performing calculations.

In addition to the scheduled wake-ups, the MTEK6000 can be brought up from its sleep mode by any one of the following:

•Connecting a portable computer to the unit's serial communication port.

•Scrolling the external display with a magnet.

•Pressing any key on the optional keypad.

•Opening the enclosure door. (If tamper switch is installed)

•Change in state of the status inputs.

•Calling the unit via modem.

•Waking up on a specified number of pulses set by the Wake Up On Pulse parameter. See Appendix A for the

Wake Up On Pulse (event driven) parameter address and the Wake Up on Pulse (event driven) section later in this chapter for more details on this feature.

•Waking up on a limit violation set by analog minimum or maximum setpoints. This is only valid when analog sampling is enabled. See Analog Sampling later in this chapter for details.

See the section on Alarm Mode later in this chapter for information on viewing and clearing alarms.

Once the unit is awake, it will automatically power-down in one minute after the operator stops interacting with it.

NOTE

The MTEK6000 will not go to sleep if the RS-232C serial cable is connected and battery life will be affected drastically.

DISPLAY MODE

In this mode, the display normally shows a two-character label and a value. You can view the next displayed label without having to open the front door by touching the scroll switch with a magnet.

In display mode, only limited parameters with assigned labels can be viewed. See Appendix A for a list of display mode parameters for your device.
