4. Timer Board

[a] Solid-State Control

1) A HOSHIZAKI exclusive solid-state control is employed in the self-contained flaker

icemakers.

2) A printed circuit board (hereafter called “timer board”) includes a stable and high quality

control system.

3) All models are pre-tested and factory adjusted.

[b] Timer Board

CAUTION

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 anti-static 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

terminals.

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.

The icemaker is controlled by the timer board for the following purposes:

1) To prevent the gear motor and the compressor from starting or stopping simultaneously.

2) To reduce remaining ice in the refrigeration casing.

3) To protect the unit in case of low water and low water pressure.

4) To protect the unit in case the bin control causes chattering.

Functions of Terminals

1) Terminals 1, 2

Power supply AC 24V.

2) Terminals 3, 4

Control X1 (GM) and X2 (CM) Relays.

When closed, energize X1 (GM) in 1 sec. and X2 (CM) in 60 sec.

When opened, de-energize X1 (GM) in 150 sec. and X2 (CM) in 90 sec.

3) Terminals 5, 6

Control X1 (GM) and X2 (CM) Relays.

When opened, de-energize X1 (GM) and X2 (CM) immediately.

When closed again, energize X1 (GM) in 1 sec. and X2 (CM) in 60 sec.

4) Terminals 7, 8, 9

X1 (GM) contacts.

8 is a movable contact, 7 is a make contact, and 9 is a break contact.

5) Terminals 10, 11

Control X2 (CM) Relays.

When opened, de-energize X2 (CM) immediately.

When closed, energize X2 (CM) immediately.

Note: 1. X2 Relay is a single pole, normally open relay, and its terminals are mounted

on the relay itself.

2. The above operation times are median. See Fig. 3 for details.
