1.0 INTRODUCTION
ColorSave 1000ST-INJ is a single-component, gravimetric masterbatch/additive feeder for injection
molding machines.
During normal operation, the device controls the weight of the masterbatch/additive (from now on
referred to as MB/AD)fed into the machine with each injection shot, using a loss-in-weight method.
By continuously measuring the weight of the material in its hopper, the system immediately detects
any deviation from the preset MB/AD weight, and automatically corrects this by regulating the current
(rpm) of the feeding screw.
If required, the feeder can operate in “constant” (non-regulated) current mode - the motor works at a
pre-selected current (rpm) without being regulated by the controller.
The MB/AD is fed directly into the injection machine’s feeding throat through a neckpiece adapter.
The ColorSave 1000ST-INJ is fitted with a feeding screw; there are 5 standard types of screw for
varying dosing ranges. Note that correct selection of the screw is instrumental in obtaining very high
accuracy.
The feeder can be equipped with an integral Venturi loader, which automatically refills the hopper
whenever its contents fall below a predefined minimum weight.
The feeder’s entire operation is automatically controlled by a powerful, sophisticated, yet easy-to-
operate control unit.

The neckpiece adapter (standard hexagonal version shown here) is used to connect the ColorSave
1000ST-INJ to the injection molding machine:
Fig. 5: Standard hexagonal neckpiece
In order to mount the ColorSave 1000ST-INJ into the injection molding machine please do the
following (refer to Fig. 2):
a) Install the neckpiece in position, between the main hopper and the injection machine’s feeding
throat, and fasten with its screws.
b) Connect the feeder to the adding flange (8) and fasten it with the quick-release star knob.
3.2.2 Releasing The Load Cell
The load cell is extremely sensitive and should always be handled carefully.
When the unit leaves the factory, the load cell is locked by its protecting device, to prevent any
damage to the load cell during transportation and installation.
After installation and before operating the feeder, release the limiting pin of the protecting device
from its "locked position" to "unlocked position"; otherwise the load cell will not be able to function.
See Appendix A: Load Cell Protection Device for unlocking instructions after installation.
Important:
Always relock the safety device whenever the ColorSave 1000ST-INJ is dismantled from the injection
machine and is being moved to another location or machine.
Note that there is no guarantee for the load cell in case of any mechanical damage, or damage
caused by an overload.

Fig. 8: Connections diagram

ColorSave 1000ST-INJ user manual
14
3.3.2 Sensor Cable Wiring Options
There are two alternatives for wiring the sensor cable to the injection machine (see Fig. 9):
Alternative A (Standard):
Connecting the "dosing" wire (black) and the "common" wire (red) to a "dosing" dry contact in the
injection machines, which is synchronized with the dosing phase –indicating the recovery phase time
(machine's screw backward motion).
Using this standard wiring will ensure the synchronization of the ColorSave operation to the injection
machine's cycle time, and MB/AD feeding during the dosing (backward motion) time.
Alternative B (Optional):
Connecting the "injection" wire (green) to another dry contact synchronized with the injection phase
–indicating the injection time (screw's forward motion).
This optional wiring will cause feeding of MB/AD both during the dosing phase and (a certain
amount) during the Injection phase as well, thus enabling better color dispersion.
Notes:
a) The "dosing" contact should always be connected in both alternatives A and B.
The "injection" contact should be connected only when a MB/AD feeding is also required
during injection phase.
b) The contacts should be No Voltage Contacts (dry contacts) only.

4.0 OPERATION
4.1 General
4.1.1 Operation Modes
The device can operate in four (4) pre-selected operation modes:
1. Mode "0"- Gravimetric loss-in-weight operation mode (regulated speed/machine feeding
time)
The speed of the dosing screw is regulated on-line by the controller according to the required
dosing rate, while the feeding time is determined by a signal (dry contact) from the injection
machine.
2. Mode "1"- Gravimetric loss-in-weight operation mode (regulated speed/constant set feeding
time):
The speed of the dosing screw is regulated on-line by the controller according to the required
dosing rate, while the feeding time is constant, as set by the operator.
Start time is synchronized with the injection cycle by a signal (dry contact) from the injection
machine.
This mode is useful in those cases where the feeding time of the injection machine is either not
steady enough, too short, or too long.
3. Mode "2"- Volumetric operation mode (constant speed/machine feeding time): The speed of
the dosing screw is kept constant, as set by the operator, independent of any variation in the
process parameters, while the feeding time is defined by a signal (dry contact) from the injection
machine, synchronized with the injection cycle.
4. Mode "3" - Volumetric operation mode (constant speed / constant time)
Two alternatives (sub-modes) are available:
1. Standard Volumetric mode: Both speed of the dosing screw and dosing time are constant, as
set by the operator. This mode is applicable if any one of screws 1-4 is selected (not the micro).
2. Micro Volumetric mode: Operator sets speed of the dosing screw and desired number of screw
revolutions per injection cycle according to required batch weight (instead of feeding time, as in
standard mode 3).
This mode is applicable only if micro screw (No "0") is installed and selected.
Using this mode enables very low dosing level, up to 2-3 granules per shot.
Possible operation modes are shown in the following table:

*When the sensor cable is wired with additional dry contact during "injection" phase (see section 3.3.2 Sensor
Cable Wiring Options), the operator sets the dosing time, and the injection time is taken from the machine.

ColorSave 1000ST-INJ user manual
16
4.1.2 MB/AD Feeding Modes
There are two alternative MB/AD feeding modes, depending on the wiring of the "sensor" cable to
the IMM (see section 3.3.2 Sensor Cable Wiring Options):
Alternative A (Standard): MB/AD is fed only during the dosing (backward motion of the IMM
screw) phase
Alternative B (Optional): MB/AD is fed mainly during the dosing (backward motion) phase;
however, a certain quantity of MB/AD will be fed during the injection (forward motion)
phase as well. This option enables better color dispersion.
Notes:
a) Timing and time duration of each phase is identified by the ColorSave controller by the sensor
input (when the relevant dry contacts in the injection machine are in "closed" state).
b) The initial feeding rate during the "dosing" phase is determined by the controller according to
the entered parameters (part weight and MB/AD percentage) and the measured dosing time.
c) The feeding rate during the "injection" phase, if applied, is 2/3 of the feeding rate during the
"dosing" phase.
d) Feeding during the "injection" phase, if applied, will be performed in all 4 operation modes.
e) The start of the "constant time" in modes 1 and 3 is synchronized always with the start of the
"dosing" phase. The time of the "injection" phase remains the time of the injection molding
machine.

4.1.4 Gram Per Rotation
The gram per rotation is a value of how many grams are being dosed during one rotation of the
screw. The ColorSave constantly calculates the gram per rotation and modifies the value
according to this calculation.
The current value of gram per rotation can be seen in the Control Parameters screen (see section
5.9 Control Parameters).
When working without recipes, each screw type has a default value of gram per rotation. Each
time a screw is changed, the default gram per rotation value is reset. During the running time,
the value of the gram per rotation will be changed and converged.
When working with recipes, each recipe has a gram per rotation value. During the time the
running value of the gram per rotation will be changed and converged.
Note that the value will not be changed in the recipe. If the recipe is reloaded, the value of gram
per rotation of the recipe will be also be reloaded.
See section 4.6 Working with recipes for more information about working with recipes.
