  • Page 24: Alarm Setpoint Adjustments

    OPERATION Series FlexSwitch ® Alarm Setpoint Adjustments Numerical Adjustment Versus Adjustment by Observation An alarm setpoint is established using either numerical adjustment or adjustment by observation. The adjustment by observation requires the customer to establish normal process operation and adjust the alarm setpoint relative to this condition. The numerical approach requires mea- suring normal and alarm process conditions with a voltmeter and setting up the instrument in the calibrate mode based on these values.

    OPERATION Series FlexSwitch ® Disconnect the voltmeter from P1. Replace the enclosure cover. Note: The alarm can be set for a specific flow rate. Follow the Air/Gas Flow Applications procedure up to step 7 except establish the specific flow rate rather than the normal flow. The output signal will be the setpoint value. Determine whether the alarm should actuate with decreasing or increasing flow and skip to the appropriate step 4 in Detecting Decreasing Flow or Detect- ing Increasing Flow, respectively.

    Application: J20 or J18 (Flow/Level) for alarm No. 1 or No. 2, respectively. Heater Power: J32 (3 watts for FLT93S/FLT93B or 0.57 watts for FLT93F). Apply power to the instrument. Verify the yellow LED is on. Allow fifteen minutes for the instrument to warm-up.
  • Page 30 OPERATION Series FlexSwitch ® Note: The output signal at connector P1 varies inversely with changes in the process flow rate. The output signal level is also rela- tive to the type of process media being measured. See Figure 3-3. Establish the normal process flow condition and allow the signal to stabilize. Record the normal flow signal value.

  • Page 31: Adjustment By Observation

    Series FlexSwitch OPERATION ® For the appropriate alarm, determine whether the status LED is on or off (red for No. 1 or green for No. 2). If the LED is on, turn the setpoint adjustment potentiometer (R26 for Alarm No. 1 or R25 for Alarm No. 2) slowly counterclockwise just until the LED turns off.

  • Page 97: Appendix D Temperature Compensation

    Series FlexSwitch APPENDIX D - TEMP COMP ® APPENDIX D TEMPERATURE COMPENSATION Introduction Temperature compensation (Temp Comp) is an essential part of the FLT FlexSwitch circuitry. When the Temp Comp is set correctly, the instru- ment stays accurate over a process temperature range of 100 °F. The instrument is a thermal dispersion device. It relies on the temperature differential between the reference RTD, which is at the process media temperature, and the active RTD, which is heated to produce a tem- perature differential (TD).

  • Page 98: Balance Procedure

    APPENDIX D - TEMP COMP Series FlexSwitch ® Balance Procedure The following steps are the flow element balance procedure required to complete the Temp Comp restoration and must be used when install- ing remote units with more than 10 feet of cable. Connect the DMM to P1 with the positive lead connected to position 1 (Red) and the negative lead connected to position 2 (Blue).
  • Page 99 Series FlexSwitch APPENDIX D - TEMP COMP ® 10. Raise the temperature of the process media to the maximum expected temperature. The difference between the low and the high tem- perature is not to exceed 100 °F. 11. Set the flow rate to the same value used for the low temperature. Note: The flow rate must be the same at both the low and high temperature.
