FOCKE MELER GLUING SOLUTIONS INTRODUCTION Optional equipment To increase the performances of the machine it is possible to improve it with the following options: • Pneumatic by-pass valve pressure control system (VP). • Double pressure solenoid valve control system (DP).
INTRODUCTION MA-5060-GBR PS20 NON STOP DRUM UNLOADER MANUAL Double pressure solenoid valve control system (DP) This solenoid valve has two air-inputs and one air-output. When the solenoid valve is not activated, the pressure to the bypass valve is equal to the net pressure supplied to the melter. At the moment this device is activated, air at a regulated pressure is introduced into the bypass valve.

• Connector for external I/O (included on the power card). Mounting the equipment The PS20 Non Stop melting equipment are equipped with wheels for their easy transport and positioning near the main machine. The four wheels turn 360°, and two are equipped with brakes. To move the...
FOCKE MELER GLUING SOLUTIONS INSTALLATION Electrical power connection PS20 Non Stop melters are designed to be connected to the electrical power supply in one possible way, depending on their power consumption: • 3-phase 400 VAC with neutral. A good ground connection is required in all cases.
PS20 Non Stop melters use standard Meler components. The entire range of Meler hoses and applicators may be connected to this equipment. Up to four hose-applicator outputs may be connected to PS20 Non Stop sys- tem melters, depending on the number of pumps installed.
FOCKE MELER GLUING SOLUTIONS INSTALLATION • External Standby_control input from the standby mode, from a non-voltage contact. The standby function is connected with a closed contact; an open contact disconnects it. • Low level_ contact no- voltage output that connects the main machine (or to a warning light tower) the adhesive level in the tank has reached the minimum limit (optional).

PS20 Non Stop melting equipment ensures a dry environment thanks to the addition of an air-drying system to these models, which provides a level of de- humidification above 99.98%. This guarantees that the adhesive is preserved without premature reticulations inside the applicator unit.
MELTER OPERATION MA-5060-GBR PS20 NON STOP DRUM UNLOADER MANUAL 5. MELTER OPERATION In this section we will introduce the method for using the melter. Although its operation is very simple, it should not be used by untrained personnel. Warning: Improper use may cause damage to the machine or injury and even death to the person using it.
FOCKE MELER GLUING SOLUTIONS MELTER OPERATION Filling the tank The tank can be equipped with a low level sensor (optional) that warns when the level of hot-melt adhesive drops below a third of the tank’s capacity. The unit will activate the external signal and, if it is connected, the corresponding warning device (white colour).
MELTER OPERATION MA-5060-GBR PS20 NON STOP DRUM UNLOADER MANUAL 3. Lift lid to activate the touch screen. 4. Unlock (1) and open the lid (2). 5. Take the adhesive block through the bag and introduce it inside the tank. 6. Close the lid and lock it.

FOCKE MELER GLUING SOLUTIONS MELTER OPERATION When an alarm appears, the control unit takes a series of steps to protect the unit. Simply correct that malfunction and the control unit will reactivate the equipment functions. The light tower system shows the following states: RED: Alarm.
MELTER OPERATION MA-5060-GBR PS20 NON STOP DRUM UNLOADER MANUAL The screen which allowed enable and disable the premelting appears. Click on the tab to activate it. The fuser grill begins to heat up to set temperature. At the same time the cylinder press with the pressure indicated in the external gauge.
Page 62
FOCKE MELER GLUING SOLUTIONS MELTER OPERATION Click on the tab to activate it. The system begins the injection cycle following the parameters esthablised (Injection time, Waiting time). During melting block, the melted adhesive falls to the down tank. Once the adhesive reached to the level detector, the fuser grid is disconnected and the pneumatic cylinder stops to press.
Air dryer filters Air filter maintenance - Clean the filter (at least twice a year) If the equipment does not work or works incorrectly, called to your Meler Representative or to the Main Office. Equipment cleaning To continue to take advantage of the melter’s benefits and to ensure the perfect mobility of its components, it is necessary to keep all its parts clean, especially the ventilation grate on the upper part of the machine.
5. To replace the panels, follow steps 1 through 3 in the reverse order. Depressurizing the system Melting equipment belonging to the PS20 Non Stop include a safety valve (a by-pass valve) that limits the maximum pressure within the system, especially during continuous pumping periods with closed applicator applicators.
MAINTENANCE MA-5060-GBR PS20 NON STOP DRUM UNLOADER MANUAL 2. Clean the remains of hot-melt adhesive on the inside of the tank. Warning: Use appropriate protective equipment for high temperatures. 3. Add the appropriate type and quantity of the new adhesive, wait for it to melt and pump at least one full tank through the system (hoses and applicators).
FOCKE MELER GLUING SOLUTIONS MAINTENANCE 5. Once completely empty, clean the any remaining adhesive from around the output hole and ramp. 6. Replace the plug. 7. Raise the discharge ramp and replace the side shroud cap. Warning: Use appropriate protective equipment for high temperatures.
