1. 05 Damping Factor 5x Samples Setup Menu The oxygen measurement can be damped by averaging successive readings from the probe This can be used to smooth out fluctuations in the process gas level and should improve stability of the readings of the system The larger the number selected here the more successive readings are averaged and the smoother the measurement will be The damping factor is not applied to the Probe EMF and Probe Temperature values used to calculate oxygen but to the oxygen value itself The pre damped oxygen value is not displayed or retransmitted via digital or analog outputs when damping is enabled the damped oxygen value is shown on the local display as well as being retransmitted via digital or analog outputs 5 3 5 Process Alarms POWER ALTES Options Enabled Disabled 06 Process Alarms Default Disabled Disabled Setup Menu This function allows the operator to Disable process alarms Configuration of the process alarms is not covered in this manual please refer to the 1732 Technical Manual for details 1732 Oxygen Transmitter A CONTROLS mws 17 This page has been intentionally left blank Operators Manual 18 NEW tech CONTROLS m 119 February 2015 1732 Oxygen Transmitter 6 ALARMS The 1732 Oxygen Transmitter has 4 alarm relays a built in alarm annunciator and an alarm log When an alarm occurs the Alarm Light will flash To find out what the alarm is2. 6 1 Checking and Accepting an Alarm Alarm Description Time title Time Activated P POWER OXYGEN TRANSMITTE Probe 2 TC Open Ct Time Activated Time Accepted Time Cleared 08 Mar 2006 03 45 29 Status Active Time of the event Alarm Status Active Accepted Self Cleared When a new alarm occurs either a process alarm or an alarm that will appear in the common alarm list the Alarm Light will flash quickly The more new alarms there are the faster the light will flash To check the cause of the alarm 1 wm 5 6 Press the ALARM A button This will put the transmitter into the current alarm mode The Setup Light will flash The alarm screen will appear displaying the cause of the alarm on the top line Press the ALARM ACCEPT button to accept the alarm Press the OPTION A button to see the next active alarm or the OPTION V button to see the previous active alarm When all the new alarms have been ACCEPTED the Alarm Light will stop flashing Accept each alarm and then press the SETUP RUN button to return to the Run Mode 6 1 1 Current Alarms To view the alarms that are still current press the ALARM A button from the Run Mode and then use the ALARM A and ALARM V buttons to view all alarms Use the DISPLAY A and DISPLAY V buttons to view the Time Activated and the Time Accepted of each alarm Operators Manual Etech February 2015 20 CONTROLS miia 1732 Oxygen Transmitter 6 1 2 Alarm Log
