1.6 Field of Application (Intended use)
The Loctite EQ RC34 Automatic Reservoir DP is equipped with an analogue low level
sensor that sends an electronic signal to a Loctite brand controller and is typically
integrated into a dispensing system that consist of a dispensing valve and one of these
controllers; LOCTITE® controller 97102, 97152 or RC15. The adhesive can be applied
directly from the original 250ml, 500gram, 1 liter, and 2 kg adhesive packages.
With the EQ RC34 Automatic Reservoir DP, anaerobic, UV Curing and cyanoacrylate
adhesive can be dispensed.
The capacity of the EQ RC34 Integrated DP Reservoir is:
-500 gr. bottle for CA Products -1 lb. bottle
-250 ml bottle for Anaerobic -1 Liter bottle
-Bottle with a φ124mm and -2kg bottle
a height of 250mm

2 Description
2.1 Theory of Operation
The original LOCTITE® bottle is inserted into the EQ RC34 Automatic Reservoir DP.
The closed reservoir is supplied with regulated, pressurized air from the LOCTITE®
controller 97102, 97152 or RC15. As long as the dispensing valve is open, pneumatic
pressure on the surface of the fluid in the original LOCTITE® bottle transports the
product through the product line.
Notice:
When connected to a controller 97102, 97152 or RC15, the automatic reservoir is
automatically pressurized when the controller is switched on and automatically
depressurized when the controller is switched off.
The depressurizing valve (1) must be in the valve position (pressurize). No "empty"
error message can be present.
The EQ RC34 Automatic Reservoir DP includes a dual point low level sensor that
detects when the level of fluid inside the bottle within the reservoir is in the "refill"
and "empty" condition. This sensor should be connected directly to a Loctite
controller (97102, 97152 or RC15) which provides the warning information and
signals, Alternatively, the Low level sensor can be connected to an external PLC or
controller.

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 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.
-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 contact with water.
4.2 Connecting the Unit
-Use only the cable and hose sets supplied.
-Connect the regulated air pressure supply from the reservoir P in (8) to pneumatic
connection P out on the controller.
-Connect the tank cord to the 9 pin D-sub connector XS2 (10) located on the rear
panel of reservoir as well as to socket XS2 on the controller.
-
-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.

9
-Connect dispensing valve.

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 (5), the EQ RC34 Automatic
Reservoir DP 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!

10
The reservoir is depressurized when the depressurizing valve (1) is in “OFF” position
and pressure gauge (2) indicates no pressure.
•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 (1) to “ON” position (pressurize).
•On the controller 97102, switch the reservoir to active with the button .
On the controller 97152, switch the reservoir to active with button .
5 Operation
5.1 First Operation
The EQ RC34 Automatic Reservoir DP is depressurized when the power switch on
the controller 97102, 97152 or RC15 is switched to the O (OFF) position or the tank
pressure gauge indicates no pressure.
In any case:
•Set the depressurizing valve (1) to position (depressurize).
•Check that the dispensing valve is connected correctly according to the instruction
manual.
Inserting the Product Bottle
Follow procedure as described in section 4.3.

11
5.2 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.
Before adjusting the Level Sensor
•Connect the tank cord to the equipment connector XS2 (10) on the reservoir as
well as to socket XS2 on the controller.
•Empty a bottle of the product you use.
•Leave as much residue in the bottle as is required in
order to prevent air getting into the product feed line.
•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.
•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:
•Switch on the power switch of the controller 97102, 97152 or RC15 to supply the
reservoir with voltage 24 VDC.
•Remove the cap from the level sensor.
•If you have inserted a prepared bottle, then turn
electrician’s screwdriver to the point, when at least the
upper of the two red LED’s illuminates. This is observed
on the LED indicator (7) on the rear panel.
•To check the adjustment, insert a full bottle and one of
the green LED’s has to illuminated. Insert the empty bottle and the adjusted red
LED has to illuminate. The adjustment is then correct.
•Put the plastic cap back.

12
Notice:
The correct adjustment is exactly the point when the sensor switches “OFF”.
Do not go beyond that point!
•Check this adjustment with a full bottle and an empty bottle again, if it is correct.
•Remove the empty product bottle.

8 Care and Maintenance
8.1 Care
-Occasionally the O-ring at the reservoir lid should be lubricated with silicone grease.
This will prolong the life of the O-ring.
Notice: Clean hands after application of grease to ensure surfaces to be
bonded are clean.
-Clean the sensor surface as required.
-Both the bottle surface and the sensor surface must be free of condensed moisture!
8.2 Cleaning
-Prior to extended idle times or when changing of the product type, clean the product
hose and the dispensing valve.
-Loosen reservoir locking knobs (5) and remove the reservoir lid (6).
-Clean product residue from the outside of the feedline hose.
-Remove the product bottle and insert a container with approx. 0.5 liter of cleaning
agent.
-Put on the reservoir lid (6) and uniformly tighten the reservoir locking knobs (5).
-Operate the dispenser continuously until dry air streams out of the dispensing valve
(see operating instructions for the dispensing valve).
-Remove the empty cleaning agent container.
8.3 Maintenance
-Check the reservoir knobs and the product feed line on a regular basis. If there is
any sign of cracks, replace them!
-Clean, dry, filtered air must be used. If it is not, the solenoids on the controller will
be fouled over time.
Notice: If the required air quality is not achieved, install a Loctite® filter
regulator. In the US order a 5 m filter using Part Number 478603. In Europe or Asia,
order a 10 m filter using Part Number 88649.
