2. CONTROLLER BOARD
[a] SOLID-STATE CONTROL
1) A HOSHIZAKI exclusive solid-state control is employed in KML-200 Series Modular
Crescent Cubers.
2) A Printed Circuit Board (hereafter called “Controller Board”) includes a stable and
high quality control system.
3) All models are pre-tested and factory-adjusted.
[b] CONTROLLER BOARD
CAUTION
1. Fragile, handle very carefully.
2. A controller board contains integrated circuits, which are susceptible to
failure due to static discharge.  It is especially important to touch the
metal part of the unit when handling or replacing the board.
3. Do not touch the electronic devices on the board or the back of the
board to prevent damage to the board.
4. Do not change wiring and connections.  Especially, never misconnect
K3, K4 and K5, because the same connector is used for the Thermistor
and Float Switch.  K4 is not connected.
5. Do not fix the electronic devices or parts on the board in the field.
    Always replace the whole board assembly when it goes bad.
6. Do not short out power supply to test for voltage.
