4 Installation
4.1 General
General rules:
- Always work with cable glands
- Be careful when drilling, so that the wiring cannot be damaged
- The wiring is not heat resistant, so do not place against hot parts
- Be careful that no cable gets stuck
- Be careful that no cables are in the path of moving parts
4.2 Groundwire
Connect the groundwire directly to the tank. If possible mounted under a bolt,
which keeps the pump in place.
4.3 Power supply
Connect the main power of the AutoFill to the incomming voltage of the hotmelt
unit. Preferably connect to the power behind the mainswitch.
4.4 Ready contact
Connect the brown and blue wire to the ‘ready’ signal from the hotmelt unit.
Use the grey and black wire for the release contact of the machine.
If the pins for the blue and brown wire are already in use, disconnect these two
wires and connect them to the grey and black wire by the thermoplastic
connector.
4.5 Alarm contact optional.
The + from the transformer has to be connected to NO by the Alarm connector.
The –from the LED/ Siren has to be connected to the –from the transformer.
The + from the LED/ Siren has to be connected to the ‘C’ by the Alarm connector.
Following work is only to be carried out by qualified personnel.
Beware of hot surface
Disconnect the power plug of the hotmelt application before opening!

Let the control unit of the Automatic Granulate Feeder turned off.
Step 1: Check if the glue is completely melted. The sensor responses different
to solid or liquid glue.
Step 2: Place the sensor in the hole in the synthetic base.
Step 3: Make sure that 2 - 4 cm from the sensor is above the synthetic base.
(depends on type of tank and desired adhesive level).
Attach the washer to the sensor
Step 4: The adhesive level must be the same as ‘adhesive level 1’ as shown
in figure 4, so that the sensor is at least 40mm in the adhesive.
Step 5: Wait at least 5 minutes for the sensor to reach the adhesive temperature.
The range in the sensor is +/- 5mm from the bottom of the sensor, till +/-
20mm from the bottom of the sensor.
Continue with chapter 5.2 to calibrate the levelsensor.
5.2 Calibrate the levelsensor
Step 1: Switch dipswitch 1 to ON. The system is in ‘calibrate mode’.
Step 2: Close the control box and supply it with power.
Step 3: The led ‘hand’ flashes. Press button ‘hand’.
High level is now saved.
The led ‘auto’ starts to flash.
Step 4: Check the adhesive level in the tank, by removing the filltower.
Make sure that the AutoFill is voltage free.
Bij het openen van de aftapkraan kan de lijm ongecontroleerd uit de opening komen.

Step 5: Open the drain vale and place a box.
Step 6: Let the adhesive level lower to below the sensor.
Drain the tank through the drain valve or by opening a gun.
Step 7: Close the drain valve.
Step 8: Fasten the filltower to the synthetic base.
Wait at least 5 minutes to ensure that all liquid adhesive is dript of the sensor.
Step 9: Press button ‘auto’. Low level is now saved.
Calibrating the sensor is now ready. The AutoFill will automatically starts to fill.
Step 10: Turn off the AutoFill by the main switch.
Step 11: Switch dipswitch 1 to OFF to save the calibrate data.
Turn off the AutoFill, before saving the calibrate data

6 Maintenance
For good operation of the system the screen and air filter on top of the filltower
need to be clean. And not stucked with glue. The air, which transports the
granulate, must be able to leave the system.
If one or both filters get stucked with glue, then it is possible that the air can’t get
out of the system. Overpressure can be a consequence.
Important: check and clean both filters regularly.
Between filltower and synthetic base there is positioned a silicon packing.
Replace this packing during maintenance. (This packing is not shown in the partslist
of chapter 7).
Note: The frequence at which the filters need to be checked is depending on the
type of glue.

8 Troubleshooter
Problem
Possible cause
Solution
Alarmlamp lights up.
(reset alarm with AUTO-
button)
Venturi does not transports
granulate.
Shake the granulate loos in the container.
Sensor does not respond
Take the sensor out of the glue.
Wear a glove and grab the sensor by the
range
(see figure 4).
Does the sensor responds now?
Then please calibrate again. (see chapter 5).
Does the sensor not respond, then check the
connection with the mainboard.
Filltower is full with
granulate
Air supply connected at the
output instead of the input at
the air valve
It might be that the air supply and the
output hose are mixed up.
In this way the air valve will open. Now the
venturi immediately starts to transport the
granulate.
Sensor does not respond
Take the sensor out of the glue.
Wear a glove and grab the sensor by the
range
(see figure 4).
Does the sensor responds now?
Then please calibrate again. (see chapter 5).
Does the sensor not respond, then check the
connection with the mainboard.
Air leakage by air valve
Air supply connected at the
output instead of the input at
the air valve
It might be that the air supply and the
output hose are mixed up.
In this way the air valve will open.
Hotmelt system does not
apply glue
Tank is compleet filled with
granulate. So many hotmelt
adhesive is applied. The tank
can not melt fast enough.
Place the washer a little bit lower at the
sensor.
So that the range of the sensor is higher in
the tank.
After re-positioning the washer/ sensor
calibrate the AutoFill again (see chapter 5).
If possible raise the temperature of the tank/
manifold.
