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.
