1.6 Field of Application (Intended Use)
The Loctite EQ RC50 Integrated Dispenser I-4.0 combines both a controller and a
reservoir into a single unit. The controller provides 2 independent digital timing
channels that provide control of 2 pneumatic outputs. These outputs can be used to
control any Loctite automatic dispense valve or pneumatic hand-held applicator. The
controller can be actuated either by the start/stop button on the front touch panel, a
footswitch(included), or external start signal. It is capable of operating in a timed or
continue mode for dot or bead dispensing applications. The reservoir can
accommodate 50ml, 250ml, 500gram, 1 liter, and 2 kg adhesive packages which deliver
adhesive to dispensing valves. The reservoir is equipped with low level sensor which
can notify the operator that the adhesive package needs to be replace. The system
also includes an integrated industry 4.0 function that enables easy remote monitoring
by Wi-Fi, Bluetooth or ethernet.
With the EQ RC50 Integrated Dispenser I-4.0, anaerobic, UV Curing and cyanoacrylate
adhesive can be dispensed.
The capacity of the EQ RC50 Integrated Dispenser I-4.0 is:
-500 gr. bottle for CA Products -1 lb. bottle
-250 ml bottle for Anaerobics -1 Liter bottle
-Bottle with a φ124mm and -2kg bottle
a height of 250mm

2 Description
2.1 Theory of Operation
The EQ RC50 Integrated Dispenser I-4.0 is connected to an external pneumatic supply.
The system is equipped with a 0 to 7 bar (0-100psi) digital pressure regulator that
regulates the preset dispensing pressure of the reservoir and controls the dispensing
during the selected dispensing time.
An uncovered bottle of Loctite product is placed directly into the EQ RC50 Integrated
Dispenser I-4.0, the feedline is inserted into the product, and the reservoir lid is
clamped in place.
It is then pressurized using clean, filtered dry air. Air within the reservoir will push down
on the liquid in the bottle and force it through the product feed line to the dispensing
valve.
The amount of product dispensed is controlled by four main factors:
-Amount of pressure in the reservoir
-Length of time the dispensing valve remains open
-Valve stroke
-Dispensing needle size
Time Mode:
1. Press the footswitch/ manual button to activate the system
2. The dispensing timer will be activated and start to dispense with preset dispensing
time.
3. After the dispensing timer has reached the preset dispensing time, the dispensing
will be stopped.
Continue Mode:
1. Press the footswitch/ manual button to activate the system
2. The system will start to dispense, and the dispensing timer will start to count the
dispensing time.
3. Once the footswitch is released or press the manual button again, the dispensing
will stop.

4 Installation
Before using the equipment for the first time check it carefully for signs of
external damage. If any shipping damage is found DO NOT USE THE EQUIPMENT –
return it to your supplier immediately.
4.1 Environmental and Operating Conditions
-Keep the pneumatic hose to the dispense valve as short as possible for optimum
dispense control.
-Keep product feedline as short as possible. The shorter the feedline the smaller the
specific resistance and lower the dispensing pressure can be. Avoid kinking of the
feedline.

10
-Use flexible pneumatic hoses and Loctite supplied product feedlines to prevent
unnecessary loads on the fittings and to ensure compatibility.
-Ensure all pneumatic and product fittings are tight.
-No direct sunlight; no UV light.
-No condensing humidity.
-No splashing waters.
-No high magnetic and intense electric field.
4.2 Connecting the Unit
-Use only the cable and hose sets supplied.
-Connect Air pressure supply to pneumatic connection (15).
-Plug the AC power cord into Power inlet (12), which located in rear side of the EQ
RC50 Integrated Dispenser I-4.0.
-For manual operation, plug the footswitch into the 9 pin D-sub connector marked
XS1, located on the rear panel of the EQ RC50 Integrated Dispenser I-4.0.
-For automated control, connect external PLC output relay to pins one and nine of
XS1.
-Insert feedline through the reservoir lid to the dimension shown below. Alternatively
use the reference line shown on the housing to set the feedline length. Cut the end
of the feedline at an angle as shown below.
-Connect dispensing valve(s).

11
-If two dispense valves are used, remove blanking plug from the reservoir lid and
replace with additional reservoir/tube fitting.
4.3 Filling and Refilling the Product Reservoir
Warning!
Never fill the product directly into the reservoir!
The pneumatic and safety devices would become clogged and therefore ineffective!
Warning!
Before loosening the reservoir locking knobs (7), the EQ RC50 Integrated
Dispenser I4.0 must be depressurized (pressure-free)!
When dispensing cyanoacrylate and an empty signal is shown, refill the product
reservoir immediately, since air in the product line results in curing of the product!
Before loosening the reservoir knobs (7), the reservoir must be depressurized!
The reservoir is depressurized when the depressurizing valve (2) is in “OFF”position
and pressure gauge (5) indicates no pressure.

12
•Loosen the reservoir knobs (7) and remove the lid (8).
•Check that there is no condensed moisture at the bottle or the
sensor surface.
•Place the bottle in the bottle holder (see the right figure).
•Check that the product bottle inserted in the bottle holder is
pressed again the level sensor.
•Insert the product feedline into the bottle and put on the lid (8).
•Uniformly tighten the reservoir knobs (7) by hand.
•Set the depressurizing valve (2) to “ON” position (pressurize).
