CONTROL PANEL
Introduction
The Viper unit uses a microprocessor based control system that monitors and controls all of the major systems and components of the machine. Temperatures and pressures are monitored, along with pumps, valves and the refrigeration system. They are managed by the control system to provide a consistently high quality product with optimal efficiency.
The control system is set up by the service provider to perform the tasks neces- sary to keep the Viper unit operating correctly. In addition to controlling the unit, the control system keeps track of the diagnostic information used when adjust- ing and/or repairing the machine.
The control system needs to be accessed in the following situations:
•Installing the Viper
•Modifying Operating Characteristics
•Checking Performance
•Servicing/Repairing the Machine
•Checking for Error Messages
The control system is accessed using the control panel located behind the lighted merchandiser. The control panel contains an LCD display and buttons shown in Figure 6.
There are 2 levels of access to the control panel: The first level can be accessed by the operator for normal operation and the second level is used by qualified service technicians for installation and service functions. The service functions can be secured (locked out) so that an operator does not have access to them.
