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.
MTEK6000 SERIES USER'S MANUAL Base Temperature The Base Temperature 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 default value of this parameter is 60.000 degrees F. Calibrate Mode Time-out The fractional portion of this parameter is the Calibrate Mode Time-out.
MTEK6000 SERIES USER'S MANUAL Cubic Unit/Pulse In or Meter Drive This parameter determines the volume unit represented by one input pulse, and is normally set to equal the drive (CF/Rev) of the meter. Standard indexes produce one pulse per revolution; therefore, the CF/Pulse will equal the drive rate of the meter. The Default value is 100.
MTEK6000 SERIES USER'S MANUAL Flow Units The flow units parameter reflects the time used to represent the flow rate. For example, if the flow rate represents cubic feet per hour, this parameter should be set to Hour. The Default value is 2. Minute Hour Day 1 2 3 Gas Day Roll Time HHMM (Hours, Minutes) This item is used in Daily and Monthly history modes to determine when the gas day ends. The time is entered in military time. For example, a standard roll time of 8:00AM is entered as 800.0.
MTEK6000 SERIES USER'S MANUAL Low Pressure Alarm Setpoint The setpoint at which the unit determines that there is a Low Pressure alarm condition. The Default value is -100. Low Supply Voltage Alarm Reset After a Low Supply Voltage alarm occurs, the setpoint at which the unit exits this condition is entered in this location. The Default is 8.0. Low Supply Voltage Alarm Setpoint The setpoint at which the unit determines that there is a Low Supply Voltage alarm condition. The Default is 8.5.
MTEK6000 SERIES USER'S MANUAL Supercompressibilty Calculated or Fixed This parameter is used to set the mode for supercompressibility calculations. If it is set to 0, then a new supercompressibility value will be calculated each time the process executes. If set to 1, the unit will use the value set in the Fixed Supercompressibility Value parameter for calculations. The Default value is 0.
MTEK6000 SERIES USER'S MANUAL It is disabled if set to 0. In this mode, the EFC should be configured to wake up on the number of pulses entered along with an hourly scheduled wake-up to record history data. Therefore, the wake up interval (seconds) parameter should be set to 3600. The Default value is 0. Units of Measure The MTEK6000 can be configured to calculate volume and flow with English or Metric units.
