PRESSURE AND LEVEL CONTROL CARD GENERAL FEATURES
Via a micro-controller, the µZ4LP allows the operator to manage the levels and the relative safety devices
linked to the two cold drink bowls. An electronic pressure switch card (amplified, linearized, and
compensated) is provided for monitoring the pressure of the gas used in the post-mix phase of the said
drink.
The Electronic Pressure Switch Card will have the following features:
• Independent level control for each bowl.
• CO
2
gas pressure reading.
• Acoustic warning signal in the event of a lack of liquid/s.
• Pressure maintained between two pre-set points by means of a relay.
The use of these mixed THT and SMD components makes it possible to maximize the services/
dimensions/quality relationship (better immunity to external troubles).
The ECU is composed of two main printed circuits:
• Power’ section including transformer, relay, and power supply.
• Logic’ section including (controller and level control circuiting).
