7. FEEDER BOWL/HOPPER
INTERLOCK OUTPUT
The Feeder Bowl/Hopper Interlock feature (TB2-1 & 2)
can be connected to a Rodix FC-40
(TB2-11 & 12) control or another FC-90
(TB2-7 & 8) control when control of a bulk material
hopper is needed. The bowl/hopper interlock will
prevent the hopper from operating anytime the bowl is
turned OFF or in "STAND BY" mode. The Auxiliary
Interlock output can also be used to drive a solid state
relay or a low wattage 12VDC air valve. A solid state
relay can operate any auxiliary equipment such as a
light stand or an air valve. To monitor the Auxiliary
Output with a PLC see the details in the Advanced FC-
Plus
90 Application Note. The Auxiliary output is
capable of switching 70 mA if an external power
source is used. The logic of the Aux. output can be
changed through the settings of S1 (see S1 Prog.
Chart). Some other features for the Aux output are:
Aux invert; bowl out of parts with alarm; and an air jet
sequence for starting air before feeding and stopping
the air after feeding.
8. SETTING THE TIME DELAYS
The sensor time delays can be set for independent
OFF delay and ON delay periods. The time delay
trimpots can be adjusted to provide the best individual
response for the feeder (0 to 12 seconds). By rotating
the adjustment clockwise, the delay will become
longer.
9. SETTING THE SOFT-START
The start-up of the control's 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,
hammering when the control turns ON.
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.
10. POWER SUPPLY
At the rated line voltage, the line isolated power supply
is capable of providing a combined total current of 100
mA at 12 VDC (40mA with a low line voltage of
100VAC or 200VAC). The total current includes the
parts sensor and any auxiliary output accessories that
are connected to the Bowl/Hopper Interlock output
terminals.
11. REMOTE SPEED CONTROL
Remote control
accomplished by the following methods:
Plus
A. 4-20mA signal from a PLC can be used to remotely
Series
Plus vary the output of the control instead of the Main
Series
Control Dial. Set S1 to the 4-20 position. The 4-
20mA input is automatically in control whenever a 4-
20mA signal is applied to the control (terminals TB2-
11 & 12). 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.
See "S1 Programming Chart" for 0-20mA.
B. 0-5VDC Analog input signal may be applied in place
of the Main Control Dial. The 0-5VDC signal is
transformer isolated from the power line. Control
cable P/N 123-145 is sold separately.
C. A Constant Feed Rate (CFR) sensor can be added
for closed loop feeder amplitude regulation. Switch
S1 needs to be set to CFR.
12. LINE VOLTAGE COMPENSATION
Fluctuations in the line voltage can cause a feeder
bowl to vary its feed rate.
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
LVC (S1) right to disable compensation.
13. INSTALLING THE CFR SENSOR
Note: Failure to adequately prepare the feeder's
surface properly may result in a Constant Feed Rate
(CFR) sensor that will not bond to the feeder. The
sensor will not be mounted until step C-6.

in the same direction as the vibration of the feeder.

direction as the vibration (see figure 2). The sensor
must be oriented correctly for proper operation.
B. CHOOSE A LOCATION for mounting the sensor
on the feeder that is smooth and that will allow the
adhesive on the sensor to bond. Avoid mounting the
sensor over ridges and bumps which can reduce the
ability of the adhesive to stick to the feeder. The
correct location will also have enough space for the
sensor's cable to hang straight down without touching
anything else.
Fig. 2 The arrow shows the direction of vibration
which is at a right angle to the spring pack.
C. SURFACE PREPARATION of the feeder is crucial
for proper bonding between the sensor and the feeder.
Please follow these steps completely.
1) The feeder should be kept between 70-100F
(21-38°C) for ideal tape application.
2) Clean a 3.5" (10cm) circular area with a solvent
like isopropyl alcohol that will not leave a residue.
As a rule of thumb, the area can be considered
clean when after cleaning the area with a solvent-
saturated, white paper-towel, the towel is as clean
as it was before wiping.
3) Using a good amount of pressure, polish the
cleaned, circular area of the feeder using a
scratch pad or steel wool. Repeat step 2, and
then go to step 4.
4) Wipe the cleaned surface with an alcohol wipe or
with a 50/50 isopropyl alcohol/water combination.
5) Dry the surface thoroughly using a low lint cloth
or a clean paper towel.
