CONTROL PANEL ASS’Y SWITCHES AND DISPLAYED MESSAGES

CONTROL PANEL ASS’Y SWITCHES

(see Figure 3)

NOTE: The Unit control panel assembly is equipped with a hidden “SECURITY SWITCH” located be- tween “FILL 1” and “ERROR RESET” control switches (see Figure 3). Pressing in and holding “SECURITY SWITCH” for 3 seconds deactivates the control switches preventing tampering with Unit normal operation. To reactivate the control switches, press in and hold the “SECURITY SWITCH” for 3 seconds.

‘‘FILL 1’’ and ‘‘FILL 2’’ Control Switches.

‘‘FILL 1’’ and ‘‘FILL 2’’ control switches, located on control panel assembly, are touch-type switches that require only pressing to activate. ‘‘FILL 1’’ and ‘‘FILL 2’’ control switches are used when filling syrup systems sold-out floats during syrup replenishing, syrup flavor changeover, or sanitizing syrup systems. After syrup systems sold-out floats have been filled, ‘‘FILL 1’’ and ‘‘FILL 2’’ switches may be used to prevent more product entering product blender tanks during BRIX test.

‘‘AUTO BLEND 1’’ and ‘‘AUTO BLEND 2’’ Control Switches.

‘‘AUTO BLEND 1’’ and ‘‘AUTO BLEND 2’’ control switches, located on control panel assembly, are touch-type switches and require only pressing to activate. These switches are used to fill product blender tanks after sold-out floats have been filled using ‘‘FILL 1’’ and ‘‘FILL 2’’ switches. ‘‘AUTO BLEND 1’’ and ‘‘AUTO BLEND 2’’ and ‘‘AUTO 1’’ and ‘‘AUTO 2’’ switches must be pressed to operate freeze cylinders beaters and refrigeration system during normal operation.

‘‘WASH 1’’ and ‘‘WASH 2’’ Control Switches.

‘‘WASH 1’’ and ‘‘WASH 2’’ control switches, located on control panel assembly, are touch-type switches and require only pressing to activate. These switches are used to operate freeze cylinders beaters with no refrigeration during sanitizing.
