The safety lid latch circuit is designed to prolong the life of the solenoid and improve initial
pick-up force. This is accomplished by providing a ½ second burst of 24-volt DC power to
the coil, then cutting back to approximately 12 volts DC. The voltage reduction circuit can
be by-passed at any time by pushing the
STOP
push button.
Should the solenoid pin become stuck ‘down’ due to locking lever interference, move the
lever slightly to free the pin and press the
STOP
push button momentarily. To prevent this
problem,
do not jam the locking lever against the solenoid pin at any time! It is not
necessary to force the handle against the pin to verify latching! Smooth and gentle
works fine.
DUTY CYCLES
Barrett standard machine maximum duty cycles are as follows:

A note about load size
. Some sludges (for instance, cast iron) are denser than others. Metal
type and fine size can affect the weight of a load. Do not be tempted to exceed the load sizes
noted above. They will accommodate most sludge types. Remember: a pound of sludge will
effectively weigh hundreds of pounds under centrifugal force. Overloading may cause
machine failure and damage to the machine or injury to personnel.
Do not overload!
THE 1101-E AND 1101-SES PANS AND COVERS ARE MATCHED SETS AND
ARE NOT INTERCHANGEABLE! DO NOT ATTEMPT TO RUN THE INCORRECT
COVER WITH THE CHOSEN PAN OR MACHINE DAMAGE MAY RESULT!
1101E EXTRACTOR PAN & COVER
When operating this machine use care to load the pan evenly to insure a good running
balance. Make sure all guards and covers are in place.
l.Before operating the machine be sure that provisions have been made to capture extracted liquid
from the outlet at the rear of the machine.
2.Adjust the cycle timer 1TRE. Barrett recommends an initial setting of three minutes for the 1101E
(the SES will require a longer cycle time. Close and latch the control panel door. (Note: The
required cycle time will vary with the application and must be determined through
experimentation.)
3.Turn power on at main disconnect; push the "Blower Start" button located on control panel door.
The green "OPEN" light will light within 2-4 seconds.
