The potentiometer (right hand rotary dial) is used for
both manual and automatic operations of the control. The
minutes for the automatic side of the control are on the
outer labeling ring (5 minutes full clockwise, 30 minutes
full counterclockwise). On manual, the percent of speed is
from the very slowest (0% - full stop) full counterclockwise
to maximum speed (100%) full clockwise.
The on/off switch (circuit breaker included) is mounted in
the control left side panel.
A. Power Source-The control operates only on 110-120 volt
A.C. Plug the power cord into an appropriate grounded
outlet and connect the yellow twist-lock connector to
the connector on the extractor motor. The output of
this unit is 0 - 90 volts D.C. and must be used with 0 - 90
volt D.C. motors up to and including 1 H.P.
B. Power Switch-Turn the power switch “on” and note
that two lights are lit on the “visual display.” This power
switch incorporates a circuit breaker to protect the con-
trol from current overload. Should this circuit breaker
open, merely reset the power on switch to reset the
breaker. This switch should be shut off at the end of
each extracting day, and the start-stop switches may be
used between extractor loads.
C. Operator Control Center-The operator may select
manual or automatic operation. To make the selection,
press the switch for the operation desired. On automat
-
ic (auto start) the light on the left of the visual display
will flash. On manual, the light on the right of the visual
display lights and stays lit while running on manual.
1. Manual Operation-The reel speed on manual is con
-
trolled by the dial on the upper right of the control. For
Manual Operation, read the inside labeling. The 0-100
indicates percent of speed. 100% is approximately 280
rpm; therefore, 50% is approximately 140 rpm. To use
manual, merely set the speed desired and press manual
start. The extractor will advance to the set speed and
remain there. This speed may be varied at any time dur
-
ing manual operation by turning the dial.
2. Automatic Operation-Your cycle time may be varied
from 5-30 minutes. Automatic operation is obtained by
pressing auto start. The time of extractor operation is
selected by the operator. To use the automatic cycle, set
the complete extracting time desired using the rotary
dial. Read the outside scale (5 minutes full clockwise
to 30 minutes full counterclockwise) then press auto
start. The reel will begin rotating slowly and gradually
increase speed until full speed is reached. This occurs
at 75% of the set cycle time. The reel continues at full
speed for the remainder of the cycle and automatically
shuts off. The manual brake may then be used to stop
the reel.
An internal selector switch allows the owner to select a
variety of automatic cycles. The extractor can be precisely
controlled to allow for a variety of extracting conditions
(temperature—moisture level—type of honey—condition of
frames). Your control comes preset for “average’ operating
conditions for your size extractor and will be the proper set
-
ting for 80 - 95% of extracting conditions. (This switch should
be changed for special conditions only). However, for your
particular extracting job, a different operation characteristic
may be desired.
To select a different operating characteristic, remove the six
phillips head screws holding the cover in place. Be sure the
control is unplugged from its Power Source. Lift the bottom
edge of the cover up turning it completely upside down as if
using the top of the cover as a hinge. In the upper left of the
upside down cover, you’ll see a small selector switch with a
center arrow and screw driver slot. Around the outer edge,
the letters A-F and the numbers 0-9 appear. The arrow will
be pointing at one of these characters. By referring to the
charts below, you may select an operating characteristic just
right for your extracting conditions. For assistance, call your
local Dadant Branch Manager.
For “average” operation, the selector switch is set on “B” for
a 30-frame, on “E” for a 60-frame, and on “D” for a Honey
Master. (The larger the extractor, the slower the acceleration
and starting and ending speeds).
