{DUTY CYCLE}.
Internal DLC Synchronous motor has
achieved its duty cycle limit of 50% ON
time (based on a 10 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 - hence the motor runs all
the time).
Condition analog input signal.
Cycle Power.
Wait for 5 minute 'cool-down' period.
DLC-XP adjusts at
power-up.
Normal Zero Calibration. Display should
read {PLEASE WAIT / ZERO
CALIBRATE}.
Wait for DLC-XP to complete Zero Calibration.
