About Your Machine The SI-1750 is designed to separate, singulate, and feed a variety of cut sheets and non-nested products. After product is loaded into the hopper, a simple push of a button starts the feed cycle. Sensors mounted on-line and on the feeder control the start and stop sequence of the feeder cycle.
Page 9
Main Features The machine is entirely powered by a single high-torque stepper mo- tor that runs off of either a 120- or 240-VAC electrical power source. Once the machine is prepared for operation, the power-up and opera- tion of the feeder is relatively easy. But to get the most out of your machine, you should first become familiar with all of the features, including controls and sensors, con- Your feeder may look slightly different than the...

Feature Descriptions of SI-1750 FEEDER Contains the all hardware, drive motor, and belts for singulating and feeding product from a stack. Gate assembly and adjustment Mounted on a gate plate directly above the feed belts, this device provides a curvature to help preshingle stacked product. When properly adjusted, a one-thickness gap is created to help singulate and eject product.

IQuipped Box Features IQuipped Box Feature Descriptions Feature Description AC power cordset connector Cordset plugs into this IEC320 connector to provide feeder with power from 115-VAC or 230-VAC outlet. Power On/Off Toggles AC power On or Off. Fuse holder Contains 2 replaceable GMD3, 3.15-Amp, 5-mm fuses. IMPORTANT: Always make sure power module is replaced exactly as removed.
Page 12
Control Interface The control interface consists of a keypad and display arrangement which allows you to not only control the operation of the feeder, but it also allows you to monitor the status of the job being run. Control Interface Features Vacuum UP/DOWN Fluorescent...
Page 13
General The control interface provides you with several different options for monitoring status, entering configuration parameters, and cycling the feeder. To fully understand how the control interface works, you must first understand the Run Display. The default menu from which you will start all control functions is called the Run Display.
Preparing for Operation Once the SI-1750 is installed, you are then ready to prepare the ma- chine for operation. To do so, you must perform several adjustments with the product you are going to be feeding. And, you must do a test When performing initial adjustments prior to run with this product to verify that it is set correctly before going on- operation, always make sure you turn Off the...
Page 15
Procedure To adjust the gate assembly for proper gap, follow these steps: 1. Slide a single sheet of sample product under the gate assem- bly. You may have to pull up on the adjustment knob to allow the product to be inserted. Excessive lowering of the gate assembly can damage product or lead to premature wear of the 2.
Page 16
Changing From Review The feeder is shipped to you with a high-tension spring in the gate Factory Set assembly. Certain types of product may demand that you change the High-Tension to gate assembly from a high-tension setting to a low-tension setting (for example, irregular shaped product).
Page 17
Review STEP 2: The side guides hold the stack of product being fed, and they guide Side Guides Setting the product through the feeder in a straight line of movement. You can adjust the side guides to accommodate different sizes of product. Objective Adjust the side guides so that the product stack maintains uniformity from top to bottom, with no drifting or binding.
Page 18
To adjust each side guide for proper horizontal spacing, follow these steps: 1. With a small stack of material in the hopper, start by loosening the bottom adjustment knob (counter-clockwise). 2. Grasp the lower part of each guide and move to the recom- mended distance from the product: 1/16 in.
Page 19
STEP 3: Review The back wedge provides proper lift to the product to help keep it off Back Wedge the table top and feed belts, and it creates the force necessary to push Adjustment product against the gate assembly. By adjusting it back and forth from the gate assembly or pivoting side to side, you can create the lift and force necessary to preshingle product against the curvature of the gate assembly.
Page 20
Objective Adjust the back wedge for proper support of the product off the table top, without creating any pinch or stress points. Procedure To adjust the back wedge for initial proper positioning, follow these steps: 1. Grasp a handful of product, approximately 2 to 2-1/2 in. (5 to 6 cm) thick, and preshingle the edges with your thumb.
Page 21
Adjusting Back Wedge for Proper Lift Make sure the edge of the back wedge assembly is parallel with the edge of the product stack. Adjust as required and then tighten knob. 6. Check that individual triangle wedges are evenly spaced to provide enough support to lift the product off the table top and feed belts, without any bowing or twisting.
Page 22
Now that you are familiar with the basic principles of using a wedge, it is simply a matter of combining these principles to all wedges. The following wedges are covered: • Combination triangle/low-profile • Separate triangle and low-profile • Separate articulating roller and low-profile •...
Page 23
Separate Triangle and Low-Profile When to use: If moving combination triangle/low-profile wedge assembly back from the gate assembly, bottom of stack still touches table top. This means you need even more mid-range support. Side Setup guidelines: Adjust the triangle wedge the same way that you would the combined triangle/low-profile wedge assembly (see previ- ous page).
Page 24
Articulating Roller When to use: Effective for very thick and/or ridged product requiring virtually no mid-range support. Setup guidelines: Adjust so that roller edges preshingle the stack against the curvature of gate assembly. Again, make sure edges of Side product do not extend back more than the mid-point of roller. NOTE: With some product that tends to bind together (for example, perforated product), it may be beneficial to separate 4 to 5 sheets of product at the bottom to provide some air space.
Page 25
STEP 4: Review The hold-down assembly consists of several adjustable rollers which Hold-Down Setting rest on top of the product as it exits the gate assembly area. With the correct amount of pressure applied to the product, the discharge belt will have the proper amount of contact and friction needed to pull product away from the gate assembly area.
Page 26
Often after you adjust the first roller you have to go back and readjust the second roller to make sure that the drag is correct. Turning Knobs Counter-Clockwise to Insert Product Turning Knob “A” Clockwise to Get Slight Drag STEP 5: Review The photo sensor labeled Flight is mounted on the line to detect a Photo Sensor...

Page 28
Manual Test To Now that you have made all the necessary adjustments for operation, it is recommended that you verify the singulation and separation of Verify product through the gate assembly area. Before you power-up and run your machine with a full hopper, manually feed several sheets of product through the gate assembly area.
How to Operate Operational Successful power-up and operation of the feeder is assured if you ap- ply each of following sets of procedures where needed: Sequences • Loading product • Quick setup/cycle sequence • Accessing the menus for setup • Starting a cycle •...
Page 30
Quick Setup/Cycle If the feeder is prepared for operation and you want get the feeder started in the quickest way possible, use the following sequence: Sequence 1. Turn power 2. Press any key to advance to “Suspended” screen. Even though the Run Display is factory-set for 3.

Accessing the If you wish to configure all the parameters of your machine via the menus, use the following sequence for accessing the menus: Menus for Setup 1. Turn power 2. Press any key to advance to “Suspended” screen. 3. Press MENU key. Menus can be customized to suit your changing 4.
Page 32
Stopping the Feeder The feeder can be stopped either manually or automatically. Pressing the STOP key will stop feed cycles and return the feeder to the “Suspended” status. When a product fails to be staged in a preset amount of time, the feeder will automatically timeout or stop.
