MTEK6000 SERIES USER'S MANUAL

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.

January 2002

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/cm2, depending upon the system of units chosen for the particular device. Default value is 14.73.
