MTEK6000 SERIES USER'S MANUAL
January 2002 3 -3
For transport or interruptible customers, this
parameter can be used to alarm when an
account has exceeded a predetermined daily
volume allocation.
Faulty Counter Alarm (EFC)
This alarm is only valid for EFC units with a
Form C switch. If any of the dual-reed
switches in the index assembly fail, pulses
to the unit would automatically switch to a
working counter input. When this happens,
the unit generates a Faulty Counter alarm
(see the section on Pulse Input to the
MTEK6000 in chapter 2 for more details).
First Time Power Alarm
First Time Power alarm is defined as the re-
application of power after interruption of the
power source. For example, whenever the
battery is disconnected and then
subsequently reconnected, the unit records
the First Time Power event.
High Flow Rate Alarm (EFC & EFM)
If the flow rate should exceed the High Flow
Rate Alarm Setpoint, a High Flow Rate
alarm will be initiated. The alarm will
remain active until the flow rate falls below
the High Flow Rate Reset parameter value.
The setpoints are user configurable with
default values of 100000 and 99990
respectively (see Appendix A for parameter
addressing for your device).
High Differential Pressure Alarm (EFM)
If the differential pressure should exceed the
High Differential Pressure Alarm Setpoint, a
High Differential Pressure alarm will be
initiated. The alarm will remain active until
the differential pressure falls below the High
Differential Pressure Reset parameter value.
The setpoints are user configurable with
default values of 1500 and 1480 respectively
(see Appendix A for parameter addressing
for your device).
High Pressure Alarm
If the gas pressure should exceed the High
Pressure Alarm Setpoint, a High Pressure
alarm will be initiated. The alarm will
remain active until the pressure falls below
the High Pressure Reset parameter value.
The setpoints are user configurable with
default values of 1500 and 1480 respectively
(see Appendix A for parameter addressing
for your device).
High Temperature Alarm
If the gas flow temperature should exceed
the High Temperature Alarm Setpoint, a
High Temperature alarm will be initiated.
The alarm will remain active until the
temperature falls below the High
Temperature Reset parameter value. The
setpoints are user configurable with default
values of 200 and 180 respectively (see
Appendix A for parameter addressing for
your device).
Low Differential Pressure Alarm (EFM)
If the differential pressure should fall below
the Low Differential Pressure Alarm
Setpoint, a Low Differential Pressure
alarm will be initiated. The alarm will
remain active until the differential pressure
rises above the Low Differential Pressure
Reset parameter value. The setpoints are
user configurable with default values of -
100 and -80 respectively (see Appendix A
for parameter addressing for your device).
Low Flow Rate Alarm (EFC & EFM)
If the flow rate should fall below the Low
Flow Rate Alarm Setpoint, a Low Flow
Rate alarm will be initiated. The alarm will
remain active until the flow rate rises above
the Low Flow Rate Reset parameter value.
The setpoints are user configurable with
default values of -100 and -80 respectively
(see Appendix A for parameter addressing
for your device).
