ALARMS and TROUBLESHOOTING
NO METERING - ALARM CODE:48
This alarm indicates that no loss in weight has been detected during the last
several cycles. After clearing the alarm, metering will continue, however the
alarm will not re appear until after you have remedied the problem.
The following conditions are required to generate the NO METERING ALARM
a.
Before this alarm is checked, the system needed to have been running for at least 24
seconds.
b.
If the MGF is in continuous or extrusion follow mode, the target rate needs to be more
than 7.5 g/min.
c.
If the MGF is in cycle mode, the target rate needs to be more than 2 grams / cycle.
If the above conditions (a and (b or c)) are met, then the MGF will compare the current bin weight
with a captured value from 24 seconds ago.
d.
If the MGF is in continuous or extrusion following mode, the difference between the two
weights need to greater than 10 times the target rate.
e.
If the MGF is in cycle mode, the difference between the two weights needs to be
greater than 5 times the target rate.
If the above condition (d or e) fails, then a counter is incremented
If the above condition (d or e) passes, then the counter is reset to 0.
If the counter gets incremented past 3, then the NO METERING alarm is triggered.
In cycle mode, the NO METERING alarm is checked only at the start of every cycle.
In continuous or extrusion following mode, the NO METERING alarm is checked every RTU
update.
LOADING TOO SLOWLY - ALARM CODE:49
If the loading feature is enabled and it takes more than LAT (Loader Alarm Time)
seconds to fill the bin to LHF (Loader High Level) grams then this alarm is
triggered.
PRIME ALARM
-
ALARM CODE:50
This alarm indicates that the 60-second Prime cycle time has ended. The Prime
function is used to prime the feeder and is accessible from the main menu. It
operates by running the feeder auger for one minute to prime the feeder then
alarms to alert the operator that the prime cycle has ended.
LOW WEIGHT ALARM
-
ALARM CODE:51
If the bin weight falls below the LWA (Low Weight Alarm) setting (Default 400g)
then this alarm will be triggered. If the bin weight rises above the LWA
parameter, then the alarm will shut off.
