Hoshizaki 73168 LED Display and Service Lock-Out, Compressor Short Cycle Protection, Alarm Signal

3.Features

a)LED Display and Service Lock-Out

This control board uses twin LED displays to show system details and diagnostic information. For control board voltage protection, a 3A 125V fuse is incorporated into the control board circuitry. A service jumper is also provided to protect against unwanted changes to the unit's settings. This service lock-out jumper is located on the

K151 connector terminals 7 and 8. See "II.D.4. Controls and Adjustments."

b)Compressor Short Cycle Protection

The start circuit of the compressor is timed such that at power-up and during any compressor off time, there will be at least a 2 minute delay before the compressor will start. This protects the compressor against short cycling and potential compressor damage or failure. To bypass the 2 minute compressor delay timer (for unit diagnostics), press and hold the rail "SET" button and move the power switch to the "ON" position.

c)Alarm Signal

Alarm signals (E1 to E9, EA and ED) are designed to protect the unit and food product. These alarms give information or warnings in the event the unit is operating out of acceptable parameters. See "III.A. Alarm Signals."

d)Service Menu

A service menu (F0 to F9) allows for viewing and setting of system operating details and parameters. See "II.D.5. Service Menu."

e)Automatic and Manual Defrost Capabilities

This unit features automatic and manual cabinet defrost capabilities. See "II.D.4.d) Cabinet Defrost."
