Operation

General information

The Ice Manger diverter valve system is designed to
direct ice from one Horizon ice machine to two ice
storage units. AUTO is the standard operating mode.
When selected, ice is directed to the lane 1 storage
unit until it reaches the MIN (minimum) set-point.
Ice is then directed to the lane 2 storage unit and
will continue to ll this lane until the FULL level is
achieved. If at any time the ice level in lane 1 storage
unit goes below the MIN set-point, ice will be directed
back to lane 1 until the MIN level is satised. When
lane 2 reaches its FULL level, ice will be directed back
to lane 1. When both lanes reach their FULL level, the
Horizon ice machine will shut off. After a 15-minute
delay, the ice machine will be ready to start as soon
as the ice level in either of the storage units drops
below the FULL set-point.

Audible alarm

In the event a system error occurs that could cause
ice shortages, the audible alarm will be turned ON
accompanied by an appropriate error message on the
LED screen. To silence the alarm, press any of the
push buttons on the control panel. This will silence
the alarm for 4 hours, however the error message
displayed on the LED screen will remain until the
problem is addressed. After 4 hrs, if the error has not
been addressed, the audible alarm will resume.

Service

System components

Follett’s Ice Manager diverter valve system consists of following major components:

• Diverter valve module

• Control panel module

• Ice transport tube lane 1 with a dedicated sensor cable 1

• Ice transport tube lane 2 with a dedicated sensor cable 2

• Ice level sensor / ice distribution module for lane 1

• Ice level sensor / ice distribution module for lane 2

System operation

The Ice Manager diverter valve system is designed to control the feeding of ice from one Horizon ice machine to two
ice storage units. There are different ice level set-points for ice storage units.

The ice storage unit for lane 1 has two ice level set points, MIN and FULL, while the ice storage unit for lane 2 has
only one - FULL. There is also a DIF (Differential) setting for each lane that initiates rell of ice.

Note: Ice Manager diverter valve system comes with factory pre-set values for MIN, FULL and DIF (differential)
parameters. If required the pre-set values can be eld modied. (See the ice level set point on page 25.)

Control logic

Ultrasonic sensors for lane 1 and lane 2 detect ice level and send an analog signal between 0.5vdc to 4.5vdc back to
diverter valve control board. This signal is converted into distance (in inches) from the sensor face to the ice surface.

An appropriate light on the control panel comes on indicating the ice level reached either MIN or FULL levels for
lane 1 or FULL level for a lane 2 units.

Auto mode

AUTO is the standard operating mode for the Ice Manager diverter valve system. In AUTO mode, the system will
automatically direct the ice according to the sensor set point levels.

On start up, when AUTO mode is selected the diverter valve directs ice through lane 1 to the ice storage unit until the
MIN level is satised.

The diverter valve will then switch and direct ice through lane 2 until its ice storage unit FULL level is satised.

If during this time the ice level in lane 1 ice storage unit drops below the MIN level, then the diverter valve will
re-direct ice ow back to lane 1 and continue feeding ice through the lane 1 until the ice storage unit MIN level is
satised again. The cycle will continue until FULL level for both ice storage units are reached.

When the ice level in both ice storage units is at the FULL level the diverter valve shuts off the signal to the ice
machine which goes into a 15 min delay. When the delay period expires, the control logic will allow the ice machine to
restart when either sensor detects ice level drop below the FULL set-point.

Note: There is a 30 second time delay function programmed into the control logic. This function requires
30 seconds of a steady ice level reading exceeding a set-point before the control logic initiates any action.
Therefore, a momentary ice level change measured by the ice level sensors will not trigger a shut-down
or divert.

Manual mode

For Ice Manager diverter valve system cleaning and sanitizing, and some special situations (see a troubleshooting
guide on page 26), a MANUAL mode is available. MANUAL mode overrides AUTO mode and allows the operator to
select the lane.

In order to switch between AUTO and MANUAL modes push the MODE SELECT button located on the control panel.
While in MANUAL mode, pressing either lane 1 or lane 2 buttons will divert ice ow accordingly.

Note: When in manual mode ice level sensors will not control the divert action, however the ice sensors will
continue to control the ice machine. When the FULL ice level in designated ice storage unit is satised the
ice machine will be shut off.

Control board

(Fig. 36)
The control board manages all functions of the Ice
Manager diverter valve system based on signals
received from lane 1 and lane 2 ice level sensors. It
diverts ice ow from one lane to another, while ice
storage units are lled and shuts off ice machine when
both dispensers are at the FULL level.

The control board communicates with the Horizon ice
machine and the sensors for the lane 1 and lane 2 via
appropriate signal cables. It supplies 120/60/1 electrical
power to the divert gearmotor assembly and monitors
the divert gearmotor position status based on inputs
from two magnetic switches mounted to the gearmotor
bracket. It also provides 12vdc power to the control
panel via the gray control cable.

Divert gearmotor

(Fig. 37)
The divert gearmotor assembly is linked to the divert
paddle assembly and manages ice ow direction.

Divert paddle

(Fig. 38)
Located inside of the body of the diverter valve module,
the divert paddle is driven by the gearmotor and
switches ice ow from one internal channel to another.

Troubleshooting

Ice shortage with audible alarm

To silence audible alarm press any push buttons on the face of the control panel. Use the chart below to diagnose
the cause.

Control Panel Error Message Indicator or Possible Cause Corrective Action

Ice machine LED is ashing and
ICEMAKER ERROR message is
displayed

Lane 1 or lane 2 LED is ashing
and SENSOR ERROR message is
displayed

Lane 1 or lane 2 LED is ashing
and SENSOR CONNECT ERROR
message is displayed

Both lane 1 and lane 2 LEDs are
alternately ashing and DIVERT
ERROR message is displayed

DIVERT TO L1 or DIVERT TO L2
message is displayed

• Signal cable between Horizon ice
machine and diverter valve module
is not properly engaged

• Horizon ice machine has shut off
on a SERVICE error

• Malfunctioning sensor • Check supply and return dc voltage

• Sensor is disconnected from a
signal cable

• Signal cable is disconnected from
diverter valve

• Both upper (lane 1) and lower
(lane 2) magnetic positioning
switches mounted to the gearmotor
bracket inside the diverter valve are
in closed or open position at the
same time.

• Divert valve fails to switch to
another lane due to lane magnetic
positioning switch not closing

• Diverter valve fails to switch to
another lane due to mechanical
jamming inside the diverter valve

• Mechanical linkage between the
gearmotor and divert paddle is
disconnected

• Check the signal cable connections

• Troubleshoot Horizon ice machine

at sensor connections. Supply
should read 12vdc between red
and black wires. Return should
read between .5 - 4.5 vdc between
yellow and black wires.

• Recycle power to sensor and see if
error clears.

• Check sensor connections to cable

• Check signal cable connection to
diverter valve

• Check both magnetic positioning
sensors. One should be closed
when it is engaged by the
positioning disc, while the other
should be open.

Note: To manually rotate the disc

depress the gearmotor brake.

• Check to be sure magnetic
positioning switch is properly
connected to the control board

• Check the positioning switch for
continuity while it is engaged by
the positioning disc

• Manually switch between lane 1
and lane 2 to free divert paddle

• Check the linkage between the
gearmotor and divert paddle

Ice shortage without audible alarm

Use the chart below to diagnose the cause.

Control Panel Error Message Indicator or Possible Cause Corrective Action

No error message • Signal cables and ice transport

tubes are not connected to correct
ice storage/ice dispenser (lane)

No error message • Ice level reading as displayed

on control panel is signicantly
different from the actual distance
between the ice and the sensor
face

No error message • Horizon ice machine goes into

TIME DELAY mode within a few
minutes of start up of lane change

• Check to be sure that signal
cables and ice transport tubes are
connected to correct lane

• Recycle power to the diverter valve.
Make sure to re-start the Horizon
ice machine which will go into
TIME DELAY mode

• Manually switch ice to another lane
and restart Horizon ice machine.
Let ice machine produce ice for 5
to 8 minutes and manually switch
ice back to the “troublesome” lane.
See if “start-up” ice clears through

• If the above procedure does not
work, investigate a potential ice
lane restriction issue (i.e. transport
tube, bulkhead ttings, sensor
distribution unit, diverter valve)

• Check ice level set-points. Be sure
they match factory settings or
drop-in requirements shown in the
Ice level set point section of this
manual on page 24
