1.2.2 For the Safety of the

P roportional

V alve

Use only original proportional valve spare parts.

Observe the maintenance schedule.

Be aware that electronic components can be damaged by static.

1.3 Unpacking and Inspection

IMS Company proportional valves are shipped complete and will work with all the controls of the vacuum loader for automatic operation. The assembled proportional valve and vacuum loaders only requirements are:

110/115 volt single-phase power supply

Compressed air at approximately 80 PSI (minimum 70 PSI; not exceeding 100 PSI)

After receipt of the proportional valve, completely inspect it for damage.

NOTE: Although v alves are packaged securely, vibration and mishandling during transit can cause damage.

The proportional valve is shipped with a complete hardware package, consisting of:

10 ft. of 1-1/2” ID Static Wire Vacuum Hose

Stainless Steel material suction wand/vacuum probe

(2) Hose clamps



2 INSTALLATION AND START-UP

The

IMS Model 150 Proportioning Valve is designed to work with IMS Series

Hopper Mount

Material Loaders and IMS

Series Just-In-Time Material Loaders. The valve converts a single inlet loader into a two inlet proportioning loader that can draw material from two sources such as virgin pellets and regrind pellets. Once connected to the vacuum loader, the vacuum loader control panel allows the user to adjust the ratio of vacuum time from one inlet to the other.

Refer to the IMS Series

Hopper Mount

Material Loader or Just-In-Time Material Loader’s manual for loader operation and instructions.

The IMS Model 150 Proportioning Valve once installed uses the vacuum loaders electrical power, control panel and air pressure to operate.

The valve starts with “inlet one” open and “inlet two” closed (“inlet one” is on top). When the loader starts running the number one inlet is open and the number two inlet remains

closed until the desired user programmed time expires. This signals the valves solenoid to energize and reroute

the valves airflow which closes “inlet one” and opens “inlet two”.

The valve remains this way until the vacuum loader completes its cycle. When the vacuum loader stops running, the valves solenoid is de-energized thus rerouting the airflow to the valve’s cylinders which r eturn them to their original positions. The cycle then repeats when the loader starts again.

2.1

Mounting Instructions

Before attempting to mount valve, be sure the vacuum loader is securely mounted to a material hopper, feed throat of machine or other equipment. Once attached, the added weight of the valve to the loader inlet can tip material loader over!

Before attempting to mount valve, disconnect all air pressure and electrical power from the loader to which the valve will be attached! Follow lock-out/tag-out procedures for safety.

Remove existing loader hose from loader inlet and put aside.

Check inlet for wear and replace if necessary. The loader inlet should be smooth and without burrs, chips, dents or other noticeable damage.

Inspect the valve’s connection port to be free of debris, you may find it helpful to apply a thin layer of silicone grease to the valves connection port O-ring. Check to make sure the set screws are backed out and not protruding into the connection port.

Refer to FIG A and FIG B for proper valve to loader orientation and installation position.

FIG A FIG B



Push valve onto loader inlet as demonstrated by

FIG

A and

FIG

B.

Once valve is connected to inlet, tighten the two set screws (located on the side and bottom of connection port) with

a

2.5mm hex key wrench. Tighten screws evenly and firmly until valve feels securely connected. Pull on valve to ensure its connection.

Make sure valve is in vertical position and square to loader. Mounting valve incorrectly could cause valve to not operate correctly or contradictory to the instruction manual.

Warning: DO NOT exceed 100 PSI.

2.3 Control

Confirm that all electrical power is disconnected from loader. Failure to comply may cause shock hazard which could result in electrocution and even death!

Locate the control panel – FIG H FIG H

Remove the (4) front panel screws using a medium sized phillips head screwdriver and set aside. Carefully remove the cover by pulling it forward and laying it down while leaving the control wires attached.

I nstructions (continued)

Depending on the serial number of your loader, the control panel attached to the loader may have slight differences in electrical input configuration. FIG I and FIG J.

The configurations differences do not affect the operation of the proportional valve.

FIG I FIG J

NOTE: Older model loaders that start with serial number EHL. Loaders serial numbers that start with this designation cannot use the proportional valve without its own control panel. Please consult the technicians at

IMS Company if your loader has this serial number sequence .

Locate the electrical connection wire to the valve FIG K. It will include a strain relief; the end will include both a blue and brown wire with wiring connectors attached. Remove locking nut from strain relief and set aside for now.

FIG

With front panel removed – located available plugged electrical input and remove plastic plug.

Fish the valve’s electrical connection wires thru now open electrical input hole.

Inside panel, attach strain relief with previously removed strain relief locking nut and hand tighten.

Loosen terminal screws with a small flat head screw driver at the #4 and #5 location

First wire terminal 5, using a pair of needle nose pliers – grasp the wiring connector of the #5 Brown Wire and gently insert it into the terminal slot, tighten the #5 terminal making sure the wire connection is secure.

Repeat the process for the #4 Blue Wire terminal above it.



2.3 Control

P anel

C onnection


If you have difficulty securing the terminal to the wire connection, you may be inserting the connector below the terminal clamp. If this occurs, loosen the terminal screw fully and then try sliding the connector from the top of the terminal towards the circuit board. Do this slowly until you reach the top of the terminal opening and then slide the connector into the terminal clamp and re-tighten.

Once you have made the connections and confirmed they are secure, reinstall the front of the control panel by using the (4) screws that you previously removed.

Before proceeding, check all newly made connections and verify they are secure.

Reattach air supply line to the installed “T” Fitting if you haven't already done so and adjust line pressure to 70 PSI.

Making sure the main power switch (FIG M) is down and in the off position, plug loader into 110/115 Volt single-phase power supply.

FIG M

Main Power Switch

Before continuing to program the valve the following must be understood.

Valve Programming Operation:

The adjustment of the valves time is proportional to the loaders overall run time.

For example – If you want a 50/50 mix and your loader has a 30 second total run time, the valve will need to switch from “inlet one” to “inlet two” at the 15 second mark.

Therefore, the loaders run time (Parameter F3) would be set to 30 and the valves run time (Parameter FE) would be set to 15. The valves setting (FE) cannot be higher than the loader run time setting (F3).

If you wanted a 70/30 mix based on a 60 second overall run time, the valves setting would be 20 seconds.

(1/3 of the overall runtime)



3 Programming the Model 150 Proportional Valve

Refer to IMS Model 200, 400, 800, 200JT or 300JT Loader operating manual for full control panel features.

9) Adjust the proportional range using to be less than that of parameter F3 (Loading Time) a.

See bottom of page 8 for clarification if needed

10) Now that the proportional time has been set, press until you reach F3

(Loading Time) and readjust from 98 to actual desired loader overall run time (greater than FE time).

11) Press to adjust F4 (Line Clearing Time) and readjust from 97 to actual desired line clearing time.

12) Press or wait 10 seconds to save the new values.

13) The proportional parameter FE will no longer be available as it now been locked out by default.

14) Press to start the new run program.

Your loader and proportional valve are now programmed and ready for use. You may connect your vacuum hose to

“inlet one” and “inlet two” using the supplied hose clamps that came with the valve and loader.

Run loader to confirm that it is running correctly and as anticipated. If you need to make adjustments to the proportioning valve, repeat steps 1 thru 14.

If you need to make other adjustments to the loaders parameters, follow the instructions that came with the loader.
