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).
• Light tower system.
• Air drying system for PUR adhesives .
Pneumatic by-pass valve pressure control system (VP)
The inlet pressure at the bypass valve is regulated by the proportional valve,
which is commanded by an external signal (0-10V signal).
By defect, the conversion is the following:
0 V --> 0 pneumatic bars
10 V --> 6 pneumatic bars
With this operating mode, the pressure at the bypass automatically varies, and
so on, the quantity of adhesive applied.
It is important to keep a minimum pump speed in order to maintain the
demanded adhesive .
