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.

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

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.

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 .
