The next diagram shows loading an empty hopper.
Notes:
• SH = loader motor shutdown time
• DT = discharge time
• VCT = valve close time
• #1 refers to when the loader is full and the high level proximity
switch is On.
When the refill does not complete by the weight level, there is a
programmable <Discharge Timer> parameter. If the valve is open for
this time, it will close so the loader can start. After the loader is full and
the motor stops, it waits for a programmable <Motor Shutdown Time>.
After this time, it will reopen the valve. This cycle continues until the
refill is completed.
