{DUTY
CYCLE}. Internal DLC Synchronous motor has
achieved its duty cycle limit of 50% ON
time (based on a 20 minute interval).
Rapidly cycling batches and wildly
swinging analog inputs will cause this
motor to run continuously. Eliminate batches that are cycling too rapidly
(e.g., changing stroke from 0 to 100% one
minute and 100 to 0% the next - the internal
drive motor runs all the time). Condition

BATCH OPERATION
Symptom Probable Cause Possible Solution
Activated batch
appears to be
running through
batches rapidly. Repeating Batch activated with Old Start
Date. For example, today is 1/22/01, You
have a repeating batch programmed to start
on 1/5/01). The display will show the 'run-
through' of all batches between the start
day and time and today. Change Batch start-time/date to current or
future date/time.
Repeating
Batch will not
start. Batch duration is set to 0 hours and 0
minutes. Duration must be greater than 0 minutes for
batch to activate.
