RPS Configuration

This menu option will allow the user to configure the 9120 for RPS functionality.

 

Alarm band (mV)

This is the millivolt difference that must be observed for the RPS to change probes.  For example, when the RPS is selecting the highest probe with probe 1 as 1055 mV and a band of 20 mV, and if probe 2 hits 1076 mV, the RPS will start counting down the Alarm Delay timer (below).  When the delay times out, probe 2 would be selected.  If probe 2 comes back in band (drops to 1075), the timers starts over again.  The range is 0 to 600.

 

Alarm delay (min)

This is the number of minutes that the RPS waits to switch probes when an out-of-band condition is detected.  Note - There is a 950 mV low limit for an alarm.  This condition is typically found during a burnoff, so the alarm will not be active when the input drops below 950 mV.

The range is 0 to 9999.

 

Selected Probe

Indicates which probe is selected.  Note – This field is only editable when the Probe select mode (below) is set to no auto switch.  The options are: Probe 1 or Probe 2.

 

Probe select mode

This determines how the specified probe is selected.  The options are: highest mV, lowest mV, or no auto switch (manual mode).

 

RPS PV Mode

This will allow the user to select the PV mode for the RPS.  The options are: %C (950 – 1300 mV), %O2 (0 – 600 mV), or mV (0 – 1300 mV).
