MTEK6000 SERIES USER'S MANUAL
3-2 January 2002
ALARM MODE
The MTEK6000 can be configured to
activate an alarm when certain conditions
are met or when user defined limits are
exceeded. You can display active alarm
messages on the optional external keypad
and display or alarm codes on the standard
display. The unit can also automatically call
a host computer running Metretek, Inc.
software programs to report alarms.
A history log is kept in the device on each
alarm condition consisting of:
• Current value
• Type of alarm (high, low etc.)
• Setpoint value (alarm limit)
• Time of alarm
• Date of alarm
• Time out of alarm
• Date out of alarm
• Extreme value alarm
Appendix A shows the standard alarms and
codes for your device.
In addition to the standard alarms, you can
program the MTEK6000 to monitor and
report on almost any condition, such as
meter tampering, liquid level, valve status,
heater status, etc.
NOTE
Additional hardware equipment and
configuration could be required for custom
alarm monitoring.
Viewing and clearing alarms using the
magnet
Alarms in the MTEK6000 can be
recognized by the flashing outer display.
This is an indication that one or more of the
standard alarms were initiated (see
Appendix A for a list of alarms and codes
for your device). To view and clear the
alarms using the magnet:
1. Apply the magnet to the scroll switch
until the outer display shows AL
XXXXXX. (See Appendix A for a list of
alarms and codes for your device). The
alarms are described later in this chapter.
2. To view another alarm, apply and
remove the magnet briefly. The unit
should advance to the next alarm code if
other alarms are active.
3. To clear an alarm, hold the magnet on
the scroll switch for approximately five
seconds until the display flashes
OK ,
indicating the alarm was cleared.
4. If more than one alarm is active, the
display will show the next alarm code.
Apply the magnet to the scroll switch for
approximately five seconds and clear the
alarm.
5. The user can now view the standard
display parameters in Appendix A.
NOTE
The ability to clear alarms with a magnet is
default in the MTEK6000. This function
can be disabled using Metretek, Inc.’s
software packages or the optional external
keypad and display. If disabled, the user
would not have access to clear alarms, only
to view parameters.
Current Day Flow Alarm (EFC & EFM)
If the current day's total volume should
exceed the Current Day High Volume Alarm
Setpoint, a Current Day Flow alarm will be
initiated. The alarm will remain active until
the value for the current day volume is reset
the next day at roll time. The setpoints are
user configurable with default values of
100000 and 99990 respectively (see
Appendix A for parameter addressing for
your device).
