Step 2:
• Leave the 2-gun block open.
• Open a valve on the color changer cata side.
• A pressure build-up occurs between the color changer and the injection valve that can cause momentary
pulses.
• Opens the guns.
• If the injection valve is tight, then no product should flow out, so the flowmeter indicator B should be steady
(white or green).
However, if it is not sealed, then fluid will come out of the gun and the flowmeter indicator light B will flash.
• Close the 2-gun block.
Step 3:
• Open the injection valve.
• A pressure build-up occurs betwwen the injection valve and the 2-gun block, which can cause momentary
pulses.
• Opens the guns.
• If the 2-gun block is tight, then there is no product flowing out, so the flowmeter indicator light B should be
steady (white or green).
However, if it is not sealed, then fluid will come out of the gun and the flowmeter indicator light B will flash.
• This procedure is of course to be adapted according to the configuration of the machine.
5.2.23. Compatibility - hoses - product -pressure
• The user of the equipment shall ensure that the working pressure stated on the hose is equal to or less than
the maximum pressure that can be delivered by the supply system.
• Do not use hoses that have been bent and not coiled.
• Use only hoses that are in good condition and free of injuries and wear.
• Use only anti-static grade air hose to connect the pump to the gun.
• All connections must be tight and in good condition.
5.3. Shutdown and start-up procedures
5.3.1. Installation stop
The automatic cycles are stopped by pressing the stop button on the HMI.
5.3.2. Switching off
• Be sure to clean the machine properly before turning it off as this can lead to clogging of the mixed circuit.
Before shutting down the system, it is recommended to drain the hoses to prevent them from clogging.
To drain the hoses, start the «Machine flushing» cycle.
• The power is turned off using the switch located on the side of the main cabinet.
5.3.3. Restart after power outage
After a power failure, it is necessary to perform a cleaning cycle before resuming production with a clean machine.
5.4. Specific settings
The catalyst pressure must always be higher than the base pressure.
