Electrical Noise
Labeling
The air contains electromagnetic interference (EMI) fields and radio
frequency interference (RFI), also known as “electrical noise.”
Usually this noise is small enough in size (amplitude) to not be a
problem. If intense enough, however, it can cause problems for other
electrical equipment.
Streamfeeder has designed the feeder with noise immunity in mind.
Even the sensors provided with the machine have a certain amount of
noise immunity built-in. However, in extremely noisy environments,
these design considerations are not necessarily immune to electrical
noise and therefore, operational problems can occur. If you suspect
any such electrical noise problems, please report it to a qualified
technician.
Streamfeeder has affixed safety labels to those areas of the Reliant
3700 Universal Friction Feeder where potential operator hazards do
exist (such as moving belts or rollers). Shown below are label
examples, along with their respective locations.

Product Guide
Gate assembly and adjustment Mounted on a gate bracket assembly above the feed belts, this device
provides a curvature to help preshingle stacked material. When properly
adjusted, a clearance is created to help singulate and feed material.
(Note:
For multiple page material, a 1 to 1.5 maximum thickness is typical.)
Table top Used to support the back wedge.
Side guides (adjustable) Holds a stack of material to be fed and helps keep it straight for proper
entry through the gate assembly area. Single adjustment knob allows you
to move side guides together or apart for different size material. Can be
positioned equally or offset.
(Note: Dual-knob design also available.)
Back wedge and adjustment Lifts the material to keep it off the table top, reduces excessive contact
with the feed belts, and helps push the material against the curvature of
the gate assembly. To achieve proper lift, adjustment wing-nuts and
locking levers allow you to slide the wedge to various positions and
angles.
Photo sensor and flexible extension Also called a
sheet-detect photo sensor, it “looks” for the leading edge of
the material to stop the feeder. For optimum setting, a flexible extension
allows you to adjust for distance and perpendicular angle to material.
Feed belts and discharge belts
Feed belts: Provides the friction and motion necessary to pull individual
material from the bottom of the stack and through the gate assembly area.
Discharge belts: Combined with the top roller hold-down assembly,
provides the friction and motion necessary to pull material away from the
gate assembly area.
Top roller hold-down assy (adjustable) A block of small rollers mounted on a movable shaft. Used to gently force
the material down on the discharge belts so that it can be controlled after it
exits the gate assembly area. To achieve proper downward pressure,
T-nuts allow you to loosen the shaft to adjust block up or down.
Control panel All connectors and switches for sensor, interface, and AC power are
located here. For descriptions, see Figure 1-2 and Table 1-2.
Discharge safety shield Provides residual risk protection to operator when feeder is running.
Built-in interlock switch stops the feeder when opened.
LOOSE PARTS
AC power cord, 8 ft. (2.44 m) IEC320 removal three-prong. Shipped loose.
Flight-detect sensor Mounted at a remote location. It "looks" for a target on-line (such as a
hold-down ski or conveyor lug) to start the feeder.

Reset button/fault indicator Labeled Reset, the primary purpose of this pushbutton switch/indicator is
to reset the feeder after: 1) a “time-out” occurs or, 2) the discharge safety
shield is opened or, 3) "miss-feed" occurs. Time-outs occur: 1) during a
misfeed or, 2) when the hopper runs out of material; or 3) flashing during
"miss" condition. Built-in indicator illuminates: 1) steady during a time-out
condition; 2) flashing during an “open” discharge safety shield.
Variable speed control This dial switch (labeled Speed) allows the feeder speed to be
synchronized with an inserter, or infeed conveyor. Turning counter-
clockwise decreases speed; clockwise increases speed.

2Preparing for Operation
!
!
!
When performing initial feeder adjustments
prior to operation, always make sure you turn
Off the main power switch and disconnect all
equipment from the electrical power source.
Failure to do so can expose you to a potential
startup and moving parts which can cause
serious injury.
Do not attempt to make any adjustments while
the feeder and machine of application are
running. Failure to do so can expose you to
moving parts which can cause serious injury.
Do not wear loose clothing when operating the
feeder.
Avoid making adjustments with loose or
unsecured parts. This can potentially damage
parts.
STEP 1:
Gate Assembly
Adjustment
Review
The gate assembly provides the curvature to help preshingle material
and the proper gap to help the feed belts pull material through the gate
assembly area — one at a time. The downward pressure (or weight) of
the stack in the hopper will provide the force to help push the material
against the curvature of the gate assembly, and help it contact the feed
belts. This preshingling will allow the gate assembly to efficiently
separate (and singulate) material.
To achieve the optimum separation, you have to use the adjustment
knob to either increase (clockwise) or decrease (counterclockwise) the
gap between gate assembly and the feed belts. Depending on the
characteristics of the material you are using, you may have to change
the gate assembly from the factory-set high spring tension to a low
spring tension. See “Changing from Factory Set High-Tension to
Low-Tension” to follow (page 7).
Objective
Adjust the gate assembly for minimum gap, with minimum pressure
on the material. Your objective is to adjust the clearance so that a
single piece of material passes without resistance. The optimum
setting should be a gap adjustment of 1.5 thickness of material.
NOTE
NOTE
Keep in mind the gate assembly works with the
wedge to provide the proper lift, curvature of the
material, and proper belt/material contact to
separate and feed one piece at a time.
Hopper refers to the space where the material is
stacked (made up of the side guides).
IMPORTANT
Feeding problems will occur with either too much
material in the hopper, or too large a gap
between the gate assembly and the material.
Once the Streamfeeder Reliant 3700 Universal Friction Feeder is
installed on your host system, you are ready to prepare the machine
for operation. To do so, you must perform several adjustments with
the material you are going to be feeding. And, you must do a test run
with this material to verify it is set correctly before you begin cycling
the feeder with your particular application. You will have to perform
this procedure for material you plan to feed.
The adjustments you must make (in order) are as follows:
1: Gate assembly adjustment
2: Side guides setting
3: Back wedge adjustment
4: Top roller hold-down assembly setting
5: Photo sensor adjustment
6: Manual test to verify

Product Guide
Preparation and Adjustments Section 2
Procedure
To adjust the gate assembly for proper gap, follow these steps:
1. Slide two pieces of sample material under the gate assembly.
You may have to pull up on the adjustment knob to allow the
material to be inserted (Figure 2-1).
2. Test the top piece for clearance. Grasp with two hands and
slide it front-to-back under the gate assembly (Figure 2-2). A
proper adjustment allows a “slight” amount of drag on the top
piece of material.
3. With the top piece removed, test the bottom piece of material
for clearance. It should move freely, without any resistance.
4. Adjust the knob on the gate assembly until the material has
the desired drag: clockwise to increase clearance,
counterclockwise to decrease clearance (Figure 2-3).
5. Remove the top piece and turn the adjustment knob
counterclockwise 1/4 turn to lower the gate assembly. This
should set the gap for the optimum 1.5 thickness of material.
6. Repeat drag tests and adjust as needed until the desired
clearance is achieved.

Gate Assembly
Adjustment
(continued)
NOTE
When feeding product with varying thickness
throughout, it may be necessary to turn both
adjustment rollers 1-2 full turns
counterclockwise to compensate for the
differential thickness. This procedure allows the
gate horizon to “float.”
IMPORTANT
The adjustment knob set screws are pre-set at the
factory to lock the knob to the threaded rod. DO
NOT OVER-TIGHTEN! Over-tightening the set
screws may damage the components.
To adjust the gate for effective material skew control, follow these
steps:
1. Repeat drag test.
2. Test the piece for uneven side-to-side drag. Grasp with two
hands and slide it front-to-back under the gate assembly. A
proper adjustment allows for equal drag on the left and right
sides of the piece of material.
3. To compensate for greater drag on one side of the material,
turn the opposite adjustment roller counterclockwise 1/8 turn.
Next, turn the other adjustment roller clockwise 1/8 turn.
4. Repeat drag tests and adjust as needed until equal drag is
achieved. You may need to repeat this procedure after
observing the feeder cycling (refer to Section 3, How to
Operate).

Product Guide
Review
The Reliant 3700 is shipped to you with a high-tension spring in the
gate assembly. This works well for most materials, allows for tall
stack height, and helps provide the best performance in preventing
doubles. However, certain types of material may demand that you
change the gate assembly from a high-tension setting to a low-
tension setting (for example, irregular shaped material).
If you are feeding a material of irregular thickness, you should
change to low-tension. This provides the following benefits:
1) allows the gate assembly to adjust to the irregular thicknesses.
2) prevents marking on the material by the gate assembly.
3) prevents peeling back the top sheet of a multi-page item.
Procedure
To change the spring from a high to a low tension, follow these
steps:
1. Remove the gate assembly from gate bracket assembly. To
do so, pull cylinder down with one hand, lift up on knob
with other, and tip at slight angle to remove.
2. Remove the adjustment knob by turning counterclockwise
(Figure 2-5A). Then lift the cylinder off of top of spring
(Figure 2-5B).
3. Turn the cylinder around so the cylinder collar faces up
(Figure 2-5C). Then place the cylinder on top of the spring.

High-Tension to
Low-Tension
IMPORTANT
When changing from a low-tension to high-
tension setting, you may have to adjust the
stack height downward to prevent feeding
problems.
!
Excessive lowering of the gate assembly can
damage material and/or lead to premature
wear of the O-rings or feed belts.
NOTE
Certain types of single-sheet material may
require even more tension than the high-
tension setting can provide. To increase
tension even further, place a washer between
the cylinder and spring.
