APPENDIX C:
PARAMETER DESCRIPTION
The parameters relative to the operation and
configuration of the MTEK6000 are listed
below (See Appendix A for the addresses of
these parameters).
Alarm Pulse Output Enable/Disable
The EFC can generate a generic pulse output
on any alarm condition. This parameter
enables the pulse output through Relay #2.
Enter 35.7 to enable or 0.0 to disable. The
Default value is 0.
Alarm Pulse Time (ms)
This parameter sets the output band width in
milliseconds (ms) for pulse outputs generated
by an alarm condition. The user should take
care in assigning a value for this parameter.
The value should always be less than the
Wakeup Interval Parameter; else the unit will
stay awake for the duration of the pulse.
Range 0 to 32,000 ms. The Default value is
70.
Analog Sampling Rate (seconds)
This parameter sets the rate at which the unit
will sample its dynamic analog input variable
channels. When enabled, the unit samples
pressure, flow temperature, case temperature
and the external analog transmitters values
once for each selected interval.
The sample’s minimum and maximum values
are then checked against their corresponding
High and Low Setpoints. If the unit
determines that these conditions were
exceeded, it “wakes up” and finds the average
of all samples accumulated since the last
process execution, displays this analog mean,
and applies it to any necessary subsequent
calculation.
To enable analog sampling, set this parameter
to 1-99 seconds. Set to 0 to disable analog
sampling.
Atmospheric Pressure
If the station is configured for ABSOLUTE
pressure, enter 0. Enter the actual
atmospheric pressure for GAUGE pressure.
The default value is 14.4 PSI for gauge and 0
for absolute.
Audit Trail Logging Enable
This parameter enables Audit Trail logging in
the MTEK6000. Examples of audit trail
events include editing any item at the device,
and logging the time it enters calibration
mode. After the maximum number of events
(250) has been logged, no more parameters
can be changed in the unit until the audit trail
is uploaded and reset by the software. This
parameter is disabled at the factory. The user
may enable Audit Trail logging by entering
250. Default value is 0 for disable.
NOTE
Once the audit trail is enabled, the user cannot
disable it without reloading the database.
Base Pressure
The Base Pressure parameter appears as a
factor in the Corrected Volume calculation. It
is one of the factors used to correct the
flowing volume, as registered by the meter
itself, to the base volume used for calculating
“Standard Volume”. The normal pressure
ranges for this parameter are 11.000 to 16.000
PSI.
The standard value for this parameter is
14.730 PSIA, 101.560 kPa, or 1.114 kg/cm
2 ,
depending upon the system of units chosen
for the particular device. Default value is
14.73.
