Timer Board - Hoshizaki DCM-500BAF Service Manual

5. TIMER BOARD

[a] SOLID-STATE CONTROL
1) A HOSHIZAKI exclusive solid-state control is employed in the DCM-500 and DCM-750
cubelet ice dispenser. This control includes a microprocessor (LSI) developed by
HOSHIZAKI.
2) A Printed Circuit Board (hereafter called "Timer Board") includes a stable and high quality
control system.
3) Any complicated adjustment is not required. All models are pretested and factory-
adjusted.
[b] TIMER BOARD
1. Fragile, handle very carefully.
2. A timer board contains CMOS (Complementary Metal-Oxide Semiconductor)
integrated circuits, which are susceptible to failure due to static discharge. It
is especially important to use an antistatic wrist strap 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 K1,
K2, K3 and K4.
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.
A timer board, Part Code 2U0098-02 (Model H2AA086C03), is used for DCM-500 and
DCM-750 cubelet ice dispensers.
Note: Be sure to use the proper Timer Board for the model that you are working on.
