Compaq MTEK6000 Faulty Counter Alarm EFC, First Time Power Alarm, High Flow Rate Alarm EFC & EFM

MTEK6000 SERIES USER'S MANUAL

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).
