5.2 ALARM STATUS MENU PAGE

Alarm Status Menu Page

STATUS NORMAL indicates normal operation. The display will indicate STATUS ALARM when

any one of the 5 alarms listed below is present.

Volume (Flow) Scale Overrun – This alarm is present whenever the volume ow rate causes the

incremental volume total to accumulate at a rate that is too fast.

To clear this alarm message, rst conrm that the ow rate data and pipe diameter data on the tag

attached to the meter corresponds with the actual ow rate and actual pipe diameter. Any

mismatch between the calibrated and actual ow rates or the calibrated and actual pipe diameter

will cause this alarm message to appear. Contact ONICON for assistance in correcting this

condition.

Heat (Energy) Scale Overrun – This alarm is present whenever the energy ow rate causes the

incremental energy total to accumulate at a rate that is too fast.

To clear this alarm, rst conrm that the actual temperature sensor readings and the actual ow

reading are within expected norms and match the calibration data provided for the System-10

BTU Meter. Either an excessively high delta temperature or an unexpectedly high ow rate can

cause this alarm message to appear. Contact ONICON for assistance in correcting this condition.

Pulse Overrun – This alarm is present whenever the incremental energy total is accumulating at a

rate that exceeds the time interval required for the 50% duty cycle of the pulse.

This alarm will normally coincide with either the volume scale or heat scale alarms. That

message must be cleared before this message can be cleared. Contact ONICON for assistance in

correcting this condition.

Top Turbine – This alarm will occur whenever zero pulses are accumulated from the top turbine

while simultaneously pulses are accumulating from the bottom turbine. To clear this alarm, the

ow meter should be physically inspected to determine why the top turbine is not rotating.

Bottom Turbine – This alarm will occur whenever zero pulses are accumulated from the bottom

turbine while simultaneously pulses are accumulating from the top turbine. To clear this alarm,

the ow meter should be physically inspected to determine why the bottom turbine is not

rotating.

System Reset Count – The last 3 digits on the display indicate the total number of system resets

that have occurred since the current version of the rmware was loaded.

Volume (Flow) Scale Overrun: OK=0; Alarm=1

Heat (Energy) Scale Overrun OK=0; Alarm=1

Pulse Overrun: OK=0; Alarm=1

Top Turbine: OK=0; Alarm=1

Bottom Turbine: OK=0; Alarm=2

System Reset Count: Number of system resets=0-255
