2 Description
The Loctite®Digital Syringe Dispenser 883976 is semi
automatic dispensing system designed for adhesives and
fluids packaged in syringe barrels. The unit has digital
timing control, with decimal control to .001 seconds for
increased precision over typical pressure time systems. An
adjustable pressure regulator controls a pulse of air, and
when used in conjunction with a airline adapter attached to
an adhesive syringe barrel, it will provide a controlled
dispense of that adhesive. Additional features include
Vacuum suck-back that can effectively control
product dripping or stringing.

5
Timed or Incremental Mode to allow adhesive to be
applied at once or in an incremental fashion.
Convenient “Teach Mode” to help determine time
required when the dispense amount is not known.
Cycle counter option displays clearly in LCD screen
The unit can also be integrated into PLC
programming to facilitate a continuous operation.

5 Operation
5.1 Set up Instructions – Manual Dispense Cycle Setting
The Manual Mode allows the unit to pulse for the duration
that the foot switch is depressed. It is typically used to start up and
purging through a dispense needle.
The unit is factory pre-set with a dispense time of 0.1
seconds. Manual mode will not function unless there is time set
in the time display. (00.000 time setting will not allow the unit to
dispense in manual mode)
5.1.1 Turn on the unit by pressing the Power button (1).
5.1.2 Press the Mode button (2) until Manual Mode appears
on the display.
5.1.3 Turn up the air pressure by rotating the Air Pressure
Regulator knob (6) until the desired pressure is indicated on
the Air Pressure Gauge (5).
5.1.4 After filling the barrel or using pre-packaged adhesive,
attach the syringe to the syringe adapter. Make certain that
the syringe locks into place.
5.1.5 Connect the plug end of the receiver head assembly to
the Air Dispense Outlet (7).
5.1.6 If vacuum “suck back” is needed, rotate the Vacuum
Regulator (8) counter clockwise until the desired vacuum
pressure is obtained.
5.1.7 Press and hold the Footswitch to activate the dispense
cycle. (The Manual Mode is now activated)
5.2 Dispense Cycle Setting – See Figure 5.1
Push the Mode button (2) to select Timed Mode or
Incremental Mode.
Timed Mode: Allows the unit to dispense for the
the complete amount of time set on the timer
when the foot switch is initiated
Incremental Mode: Allows the unit to dispense
for as long as the foot pedal is depressed and will
continue till the set time is reached. This allows a

8
pre-determined amount of product to be
incrementally added in steps if desired.
5.2.1 Setting the Timer in the Timed Mode
5.2.1.1 From the Timed Mode , press and hold button the
Set button (3) for 2 seconds. The unit will enter
the Set- up Mode and allow each or the time
digits to be set.
5.2.1.2 Pressing the Set button (3) from this point moves
the the cursor to the next digit and back till the
desired time has been set
5.2.1.3 Press the (+) and (-) button to set the time for
each digit desired. (You can not go past 0 with
either button.) Minimum dispense time is 00.020
seconds
5.2.1.4 When your desired time has been entered, press
and hold the Set button (3) for two seconds to
save the data.
5.2.2 Setting the Timer in the Incremental Mode
Setting the timer from the Incremental mode, “Teach
Mode” is helpful in determining dispense time
required when dispense output is unknown. The timer
will continue to accumulate time as long as the foot
pedal is depressed, allowing the user to “teach” the
unit the exact time needed
5.2.2.1 From the Incremental Mode, press and hold the
Set button (3) to enter the “Teach Mode”. The
unit will still read Set-up, however the time will
show “0.000” in the LCD.
5.2.2.2 Press and hold down the foot switch. Product
will dispense and time will accumulate. Continue
to release and press the foot switch till the desired
quantity has been dispensed.
5.2.2.3 Press and hold the Set button (3) for two seconds
to save the data.

9
5.2.2.4 Press the Mode button (2) to switch the Timed or
Incremental Mode as desired. The dispenser is
now ready to dispense this new time cycle
5.2.3 Resetting the Cycle Counter
The cycle counter records the numbers of automatic
dispense cycles being activated. Up to 65,535 cycles
can be recorded. This number is shown at the lower
right hand corner of the LCD. To reset the counter;
5.2.3.1 Press and hold the Set button (3) for two seconds
to enter the Set up mode.
5.2.3.2 Then re-press and hold the Set button (3) for three
to five more seconds to reset the counter. After
two seconds the screen will first show “Saving
Data” but continue holding till the cycle counter
resets to 00000 .
