Theory of Operation

The Semi-automatic Dispense System is connected to an external pneumatic supply. It regulates
the adjusted dispensing pressure and controls the dispensing during the selected dispensing
time.
An uncovered bottle of LOCTITE product is placed directly into the integrated reservoir, 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 feedline to the dispensing valve.
The amount of product dispensed is controlled by three main factors:
– Amount of pressure in the reservoir
– Length of time the dispensing valve remains open
– Dispensing needle size
Additional Features (97009 only)
Two additionally features are available from batch no. 2FFE0001.
EMPTY:
If the reservoir is empty the contact of the level sensor opens. A beeping tone indicates the
message and the sign "U" is displayed.
READY:
If the dispensing cycle is finished and the reservoir is not empty closes a contact.
Both signals are available as dry contacts at the XS 1 start interface for optional connection to a
higher-ranking controller or a warning light.
The start of a dispensing cycle is not locked when EMPTY is indicated.
Pay attention if cyanoacrylate is dispensed – Air in the feedline results in curing of the product!
When the user quits the EMPTY message and the beeping tone with the button ENTER the
signal at the interface XS 1 is quit, too.
The READY signal will only be indicated, when the reservoir is refilled and the sensor is
activated.
