4. SETTING THE MINIMUM
OUTPUT LEVEL OF CONTROL
When the vibratory feeder is nearly empty, turn the
MAIN CONTROL DIAL
to “1” and adjust the
MIN
trimpot to just below the slowest speed that provides
the proper feed rate. The MIN trimpot also serves as
the “low speed” trimpot for 2-speed operation. See
“S1 Programming Chart” for feature selection details.
5. MAIN CONTROL DIAL
The output power is controlled by the
MAIN
CONTROL DIAL
. It is a logarithmic-tapered power
out curve (non-linear) that spreads the power broadly
across the
MAIN CONTROL DIAL
The logarithmic
taper power curve helps to give maximum "Fine
Control" over the output speed of the vibratory
feeder. When very precise adjustment of the
MAIN
CONTROL DIAL
is needed, increase the MIN
trimpot setting and/or decrease the MAX trimpot
setting. For precise scaling at low amplitudes, use
the linear POT taper or reduce the Max pot setting.
To select a linear pot taper for the Main Control Dial,
see the “S1 Programming Chart.”
6. SETTING THE SOFT-START
The start-up rate of the control output can be
adjusted to ramp up to the desired output level
instead of starting abruptly. Soft-start keeps parts
from falling off the tooling, reduces spring shock, and
hammering when the control turns ON. Turn the
SOFT
Start trimpot clockwise for the gentlest start
(about a 6 sec. ramp up to full output). Turn the
trimpot fully counter-clockwise for no soft start.
7. LINE VOLTAGE COMPENSATION
Fluctuations in the line voltage can cause a feeder
bowl to vary its feed rate. The line voltage
compensation feature adjusts the control's output to
help compensate for fluctuations in the supply
voltage. If it becomes necessary to disable this
feature, set “Disable LVC” from the S1 programming
chart
8. REMOTE SPEED CONTROL
Remote control of the power level can be
accomplished by the following methods:
A. 4-20mA signal from a PLC can be used to remotely
vary the output of the control instead of the Main
Control Dial. The 4-20mA input is automatically in
control whenever a 4-20mA signal is applied to the
control (terminals TB2-8 & 9). The Main Control
dial setting is ignored whenever there is a 4-
20mA signal. The 4-20mA input is transformer
isolated from the power line. In an environment
with high electrical noise, use a shielded cable
for the 4-20mA signal. The “S1 Programming
Chart” shows how change to 0-20mA speed
control instead of the default of 4-20mA.
B. A 0-5VDC Analog input signal may be applied
in place of the Main Control Dial at H1. The 0-
5VDC input is transformer isolated from the power
line.
9. SUPPLEMENTARY FEATURES
Special supplementary software features can be
enabled on the 24-210/24-211 circuit boards The
features include:
linear pot taper
,
0-20mA control
,
e
mpty bowl timer
,
low pulse rates,
and
two speed
pots
. See the S1 Switch Programming Chart.
Contact the manufacturer for more information.
10. STATUS LEDs
When any of the inputs are active, the associated
LED will turn ON. When the RUN input conditions
are met, the RUN LED will turn ON. See section 3
and the wiring diagram’s ON/OFF Control Guide
for more information on how to satisfy the RUN
conditions.
WARNING:
Fuses should be replaced with a Bussman
ABC or Littelfuse 3AB "Fast Acting" type or
equivalent of manufacturer's original value.
Mounting this control directly to a vibrating
device will void the warranty.
TROUBLESHOOTING
Basic Procedure – To ascertain whether the
problem lies in the controller, take the following
steps:
A. Check for good fuses. Disconnect the input
power and tighten the screw terminals.
B. For the control output to be on: Make sure that
the proper input power is present. The
MAIN
CONTROL DIAL
must be turned up or if the
4-20mA input is used, it must have over 5mA.
Either the DIRECT LED must be lit or both
the INTERLOCK and EXT VOLTS LEDs must
be lit. Anytime the output is turned on, the
RUN LED will be ON. To light the DIRECT
LED, a Run Jumper must be connected at
TB2-6 & TB2-7. To light the INTERLOCK
LED, a Run Jumper must connect TB2-5 to
TB2-6. To illuminate the EXT VOLTS LED, a
10-30 VDC signal has to be present at TB2-11
& 12. See the section titled “
Remote OFF/ON
control
” for more information.
C. Connect an AC voltmeter across the LOAD
terminals (with the LOAD connected) and vary
the
MAIN CONTROL DIAL
from minimum to
maximum. In 120 pulse mode, the output
should vary from approximately 30% to 98%
of the input voltage depending on the setting
of the
MIN
and
MAX
trimpots. In 60 pulse
mode the output should vary from 20% to
around 85% of the input voltage.
D. On new installations: If the Feeder only hums
but it doesn’t feed any parts, try changing the
60/120
DIP switch (S1) to the opposite
position.
When neither a humming sound nor any vibration
can be detected in the vibratory feeder, the
problem may be in the controller.
