1.6 Field of Application (Intended use)
The Loctite EQ RC40 Integrated Dispenser 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

5
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
continuous 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 system is also equipped with a low level
sensor which can notify the operator that the adhesive package needs to be
replaced.
With the EQ RC40 Integrated dispenser, anaerobic, UV Curing and cyanoacrylate
adhesive can be dispensed.
The capacity of the EQ RC40 Integrated dispenser 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 Loctite EQ RC40 Integrated Dispenser is connected to an external electrical and
pneumatic supply. The system is equipped with a 0 to 7 bar (0-100psi) 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 RC40 Integrated Dispenser, the tube 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

6
Time Mode:
1. Press the footswitch to activate the system.
2. The dispense timer will be activated and start to dispense with preset time.
3. After the dispensing timer has reached the preset dispensing time, the dispensing
will be stopped.
Continuous Mode:
1. Press the footswitch 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, the dispensing will stop.
Additional Features:
EMPTY Signal:
If the reservoir is empty the contact of the level sensor opens. Three different types of
Empty Signal can be selected.
Mode 1: Digital Only
Mode 2: Digital + Lamp
Mode 3: Digital + System Stop
READY Signal:
If the dispensing cycle is finished and unit is not dispensing, a contact is closed and a
<READY> signal is communicated. The ready signal only indicates that the dispensing
is either ON (busy) or OFF (ready). This signal is independent of any other conditions.
Both EMPTY and READY signals are available as dry contacts at the XS1 start interface
for optional connection to an external PLC. Any external sources need to be
programmed to suit end user requirements.
In Mode 3, the ready signal will be communicated even though an Empty signal may be
communicated, however, the system will not dispense.
Caution!
Pay attention if cyanoacrylate is dispensed –Air in the feed line results in curing of the
product!

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 fitting and to ensure compatibility.
-Keep all fittings tight.
-No direct sunlight; no UV light.
-No condensing humidity.
-Avoid direct connect with water.
4.2 Connecting the Unit
-Use only the cable and hose sets supplied.
-Connect Air pressure supply to pneumatic connection (22).
-Connect power adapter with cord supplied to 24VDC power in connection (23).
-For manual operation, plug the footswitch into the required 9 pin D-sub connector
marked XS1 (see section 5.2), located on the rear panel.
-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 (6), the EQ RC40 Integrated
Dispenser 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!
The reservoir is depressurized when the depressurizing valve (12) is in “OFF”
position and pressure gauge (14) indicates no pressure.

12
•Loosen the reservoir knobs and remove the lid.
•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.
•Uniformly tighten the reservoir knobs by hand.
•Set the depressurizing valve (12) to “ON” position (pressurize).

Press both + to change the setting when Lock-Out Mode is “ON”.
5.12 Adjust the Level Sensor
Notice:
The level sensor is set in manufacturing and can be adjusted according to the type of
product used, the size of the bottle, and orientation of the basket with spacers if
required. If small bottles are used the supplied Bottle spacer disc can be placed in
the base of the reservoir to raise the height of the bottle to reduce the residual
adhesive in the bottle when low level is used.

17
Before adjusting the Level Sensor
1. Remove the plastic cap from the backside of reservoir.
2. Empty a bottle of the product you use.
3. Leave as much residue in the bottle as is required in
order to prevent air getting into the product feed line.
4. Insert the product bottle. For small bottles use the bottle
holder. For 250ml product bottle, pay attention to ensure the
bottle is aligned with the level sensor.
5. Check that the product bottle inserted into the bottle
holder is pressed against the level sensor. Only then the correct adjustment of the
level sensor is possible.
Procedure to Adjust the Level Sensor:
1. Turn power switch (1) - “ON”.
2. Remove the metal screw from the level sensor.
3. With an electrician’s screwdriver, find the point at which
the sensor switches to the condition inactive. The LED is
OFF”.
4. Check this adjustment with a full bottle and an empty bottle again.
5. Refit the metal screw to the level sensor.
6. Put the plastic cap back.
Notice:
The correct adjustment is exactly the point when the sensor switches “OFF”.
Do not go beyond that point!
