Page 4 OPERATION
OVERVIEW OF OPERATOR INTERFACE
The zone controllers are setup and monitored by a
computer based machine control system. The controller
continuously monitors the conditions and operation of
connected zone controllers and directs their operation.
The panel user interface has been designed to allow an
operator to efficiently access and control the operation of
the zones. The control panel screen is used for graphic
screens. By pressing a key on the keypad, the labeled or
described function is recognized by the control processor.
The following information in this manual is presented to
help the operator interact with the graphic screens and the
Quantum™ evaporator control panel. This manual is
intended to describe all presently available features.
OPERATOR ACCESS
Operator access to this system is through various screens.
A screen is the physical representation of data on the
screen. Icons have been used to help an operator quickly
identify functions. An icon is a small graphic symbol
representation. Each screen has a title area. The title is
descriptive of the screen. The current date and time is
shown in this title area. The day of the week, Sunday
(Sun.) through Saturday (Sat.) is displayed. The month of
the year from January (Jan.) to December (Dec.) is
displayed. The day of the month from 1 to 31 and the year
from 0001 to 9999 is displayed. The time displayed is the
current time in 24 hours (military) format. The hours,
minutes and seconds are displayed. The labeled keys on
the panel keypad provide quick access to the operator's
needs. By pressing a labeled key on the keypad, the
corresponding function is recognized. Most of the screens
have keys that describe or show a function that is
recognized when the coinciding key found at the right of
the screen is pressed. The screen keys provide access to
other screens or commands. For easier viewing, related
information is separated into boxes. The setup and
setpoint entry is separated into logical control
components. Setup selection of features and options has
been provided to prevent the operator from unnecessary
viewing and entering of unused control settings. The
required control settings are clearly presented. To further
assist the operator, an on-line help is provided.
Sometimes selections appear differently to indicate that
the feature is unavailable.

valve regulates the suction valve based on
its setpoints.
· Satisfied - The zone is in a temperature
control mode and the liquid valve is closed
because the control temperature is less than
or equals the liquid off setpoint. During this
time, the suction valve is open.
· Defrost – The zone is using defrost control
setpoints.
· Heating - The zone is using heating control
setpoints.
· Mode - One of the following messages is shown:
· Off – The zone is disabled from being
controlled. All valve station solenoids as well
as fan motor starter(s) are de-energized.
· Mode 1 - The zone was sent a command to
use the Mode 1 setpoints for control.
· Mode 2 - The zone was sent a command to
use the Mode 2 setpoints for control.
· Mode 3 - The zone was sent a command to
use the Mode 3 setpoints for control.
· Auto – Mode 1 - The zone is being
controlled using the Mode 1 setpoints that
are presently activated by the “Time

data is saved, even if there is a power outage.
To resume normal operation it will be necessary to go
through the following steps:
1. Correct the conditions causing the alarm.
2. To clear or reset the “Alarms/Shutdowns” screen
and turn off any alarm annunciation device, from
the screen press the [Clear Alarms] key. This
will also clear the “ALARM” or “SHUTDOWN”
message from the “Operating Status” screen.
3. If the conditions causing the alarm have not been
corrected or a new fault has occurred, a new
“ALARM” or “SHUTDOWN” message will appear.
The Alarms/Shutdowns history screen keeps a
record of the alarms and shutdowns. This
information will help troubleshoot persistent
operational problems.
Refer to the “Alarms/Shutdowns Message” section for a
list of all the possible alarms.

MAIN MENU SELECTION -
“CONTROL SETUP” SCREEN
This screen is accessible from the main menu screen.
From this screen, the operator can access the screens
that are used to setup the temperature, and defrost control
setpoints along with scheduling the time of day to use
these controls for this zone. After responding [OK] to
changing these control setpoints, they are written to the
evaporator board’s EPROM and read back from there to
be re-displayed. EPROM memory is non-volatile and all
information is retained even if the power to the panel is
lost. This process is used to confirm that an evaporator
control board properly receives control setpoint changes.
The following are the “Control Setup” screen selections:
· [Temperature Setpoints]
· [Mode 1]
· [Mode 2]
· [Mode 3]
· [Time Schedule]
· [Defrost Schedule]
· [Defrost Setpoints]
· [Heating Setpoints]
· [Safety Setpoints] – (enhanced unit only)

CONTROL SETUP -
“TEMPERATURE SETPOINT” SCREENS
Temperature settings are used to control temperature.
Three separate groups of setpoints (modes) can be used
to control one zone’s temperature. A time schedule is
used to select which mode to use at what time of day.
Lower or higher temperature settings can be setup in the
different modes. Higher temperature setpoints can be
used to reduce energy consumption. When the plant is
unused or used much less such as at night or on
weekends, less energy is lost in refrigerated rooms from
door openings, so higher temperature settings can be
used.
The following is a list of the temperature setpoint screens:
· Mode 1
· Mode 2
· Mode 3
Below is an example of a temperature setpoint screen:
CONTROL SETUP - TEMPERATURE SETPOINTS
– “MODE 1 SETPOINTS” SCREEN
Below are the temperature setpoints:
Basic Unit Setpoints
· Liquid On - If the control temperature equals or
exceeds this setpoint, the output for the liquid valve
will be energized or turned on to open a liquid valve
and therefore provide cooling.
· Liquid Off - If the control temperature is less than or
equal to this setpoint, the output for the liquid valve
will be de-energized or turned off to close a liquid
valve and therefore prevent further cooling.
· Heat On - If the control temperature is less than or
equal to this setpoint, control switches to using the
heating setpoints. For further information, reference
the Control Setup – “Heating Setpoints” screen.
· Heat Off - If the control temperature equals or
exceeds this setpoint after completing the “Pre-Heat”
stage of heating, control stops the heating and
proceeds to the “Post-Heat” stage of heating so as to
properly exit from heating. For further information,
reference the Control Setup – “Heating Setpoints”
screen.
· High Temperature Alarm - If the control temperature
is greater than or equal to this setpoint, for its time
delay, an alarm occurs.
· High Temperature Alarm Time Delay - The time in
minutes that the control temperature must remain
greater than or equal to the low temperature alarm
setpoint before notification of the alarm.
· Low Temperature Alarm - If the control temperature
is less than or equal to this setpoint, for its time delay,
an alarm occurs.
· Low Temperature Alarm Time Delay - The time in
minutes that the control temperature must remain less
than or equal to the low temperature alarm setpoint
before notification of the alarm.
· Delay between Modes - When starting to use the
setpoints of another mode, this is the time in minutes
that must elapse before evaluation and notification of
alarms.

Single Speed Fan Control Settings:
· On - If the control temperature reading equals or
exceeds this setpoint, the fan high-speed output
will be energized or turned on to run the fan.
· Off - If the control temperature is less than or
equal to this setpoint, the fan high-speed output
will be de-energized or turned off to stop the fan.
Variable Speed Fan Control Settings:
· On - If the control temperature reading equals or
exceeds this setpoint, the fan high-speed output
will be energized or turned on to run the fan.
· Off - If the control temperature is less than or
equal to this setpoint, the fan high-speed output
will be de-energized or turned off to stop the fan.
· Setpoint - The difference between this
temperature setpoint and the control temperature
reading is compared to the “deadband” setpoint.
If the difference is within the deadband, no
change is made to the analog signal affecting the
fan speed. If the control temperature reading is
higher than this setpoint and the difference
exceeds the deadband, then the difference is
multiplied by the “rate of change” setpoint and
the analog signal is increased by this amount to
increase the fan speed. If the control temperature
reading is lower than this setpoint, then the
analog signal is decreased by this amount to
reduce the fan speed.
· Deadband - The difference of the temperature
setpoint and the control temperature reading
must exceed this temperature span before
changing the fan speed.
· Rate of Change - This is the percent that is
multiplied to the difference of the temperature
setpoint and the control temperature reading
when this difference exceeds the deadband. If
the control temperature reading is higher than
this setpoint, then the analog signal to the fan is
increased by the result to further increase the fan
speed. If the control temperature reading is lower
than this setpoint, then the analog signal is
decreased by this result to further reduce the fan
speed.
· Delay - This is the minimum time in seconds to
delay before re-evaluating if the difference
between the temperature setpoint and the control
temperature reading exceeds the deadband
setting.
· Min (Minimum) - This is the minimum percent of
the analog signal that is sent to affect the fan
speed when the “On” setpoint is first reached and
the fan is turned on.
Fan Cycling settings:
· Time On – When the fan is turned on it will
remain turned on for this number of minutes.
· Time Off – When the fan is turned off it will
remain turned off for this number of minutes.

Enhanced Unit Setpoints
· Humidity Control On - If the humidity reading is
less than or equal to this setpoint, the humidity
output will be energized or turned on.
· Humidity Control Off - If the humidity reading
equals or exceeds this setpoint, the humidity
output will be de-energized or turned off.
Two-Speed Fan Control settings:
· Temperature On - If the control temperature
reading equals or exceeds this setpoint, the fan
low speed output will be energized or turned on
to run the fan at low speed.
· Temperature Off - If the control temperature is
less than or equal to this setpoint, the fan low
speed output will be de-energized or turned off to
stop the fan.
· Low - High temperature - If the control
temperature reading equals or exceeds this
setpoint, the fan low speed output will be de-
energized or turned off and the fan high speed
output will be energized or turned on to run the
fan at high speed.
· High - Low temperature - If the control
temperature is less than or equal to this setpoint,
the fan high speed output will be de-energized or
turned off and the fan low speed output will be
energized or turned on to run the fan at low
speed.
· High – Low Delay – The amount of time in
minutes to delay before starting the low-speed
fan after the high-speed fan has been stopped.
This time is intended to be the time it takes for
the high-speed fan to slow down and eventually
stop.
Two-Step Fan Control settings:
· Temperature On - If the control temperature
reading equals or exceeds this setpoint, the fan
step 1 output will be energized or turned on to
run the step 1 fan or fans.
· Temperature Off - If the control temperature is
less than or equal to this setpoint, the fan step 1
output will be de-energized or turned off to stop
all fans.
· Step 2 On - If the control temperature reading
equals or exceeds this setpoint, the fan step 2
output will be energized or turned on to run the
step 2 fan or fans.
· Step 2 Off - If the control temperature is less
than or equal to this setpoint, the fan step 2
output will be de-energized or turned off to stop
the step 2 fan or fans.
Modulating Valve:
Note: The suction valve must be direct for this
control.
· On – If the control temperature reading equals or
exceeds this setpoint, the suction valve output
will be energized to open the valve.
· Off – If the control temperature reading is less
than this setpoint, the suction valve output will be
de-energized to close the valve.
· Setpoint – The difference between this
temperature setpoint and the control temperature
reading is compared to the “deadband” setpoint.
If the difference is within the deadband, no
change is made to the analog signal of the
modulating valve. If the difference exceeds the
deadband, then the difference is multiplied by the
“rate of change” setpoint and the analog signal is
increased by this amount to further open the
suction valve if the control temperature reading is
higher than this setpoint. The analog signal is
decreased by this amount to further close the
suction valve if the control temperature reading is
lower than this setpoint.
· Deadband – The number of degrees in
temperature that the difference of the
temperature setpoint and the control temperature
reading must exceed to change the analog signal
to the suction valve.
· Rate of Change – This is the percent that is
multiplied to the difference of the temperature
setpoint and the control temperature reading
when this difference exceeds the deadband. If
the control temperature reading is higher than
this setpoint, then the analog signal to the
modulating valve is increased by the result to
further open the suction valve. If the control
temperature reading is lower than this setpoint,
then the analog signal is decreased by this result
to further close the suction valve.
· Min (Minimum) – This is the minimum percent of
the analog signal that is sent to the modulating
valve when the “On” setpoint is first reached and
the suction valve has opened.
· Delay – This is the minimum time in seconds to
delay before re-evaluating if the difference
between the temperature setpoint and the control
temperature reading exceeds the deadband
setting.
Temperature control is used to maintain a temperature.
The liquid valve is open to provide cooling. The suction
valve is also open during temperature control. Fan cycling
based on temperature can aid in energy savings. If the
temperature falls below the “Fan Off” setpoint the fans will
cycle off by de-energizing the proper output. There are
two setpoints that allow the operator to turn on and off the
fans for a period of time to provide for air movement while
the fans are cycled off. If the operator selects fan cycling
and the fans are cycled off, the fans will remain off for the
entered number of “Off” minutes. After the fans are off for
the entered amount of minutes and the air temperature is
still below the “Fan Off” setpoint, the fans will be
energized for the “On” number of minutes. This on/off
cycling continues until the temperature rises above the
“Fan On” set point in which the fans start and continue to
run.

CONTROL SETUP -
“TIME SCHEDULE” SCREEN
This screen shows a time schedule. The “Time Schedule”
is a schedule of what time of day to start controlling the
temperature of the zone by using either Mode 1, 2, or 3
control setpoints or turning off control. The modes can be
used to maintain different temperatures. One mode could
be used to save energy. For example, at night or on
weekends, when room doors are kept closed, a higher
temperature can be set to reduce energy consumption.
The “Time Schedule” is used to select which set of control
setpoints (mode) to use based on the time of day. Each
unit can have up to four different start times scheduled per
day that can vary each day of the week. An entry of “-” will
void the time entry field. The “Time Schedule” is only used
if the zone is in automatic mode. The time schedule is
used to switch the active control mode to another mode at
a start time.
The following is a description of the setpoints:
· Start – The time of day to switch to another
mode of control. The time of day is represented
using a 24-hour clock, i.e. 00:00 is midnight and
23:59 is a minute before midnight
· Mode - Three separate groups of setpoints
(modes) can be used to control one zone’s
temperature. The following modes can be
selected.
· Mode 1
· Mode 2
· Mode 3
· Off

CONTROL SETUP -
“DEFROST SCHEDULE” SCREEN
The “Defrost Schedule” is a schedule of what time of day
to start defrosting the zone. The time of day is
represented using a 24-hour clock, i.e. 00:00 is midnight
and 23:59 is a minute before midnight. Each unit can have
up to eight defrosts scheduled per day that can vary each
day of the week. An entry of “-” will void the time entry
field. If liquid override is enabled, these times are also
dependent on a “Liquid counter” setpoint. The liquid
counter counts a cumulative time that the liquid solenoid
output is open between defrosts. When the panel reaches
a time in the Defrost Schedule and the liquid counter
exceeds the “Liquid counter” setpoint, then the unit goes
into it’s defrost mode. If the counter has not exceeded the
“Liquid counter” setpoint, no defrost is initialized. There is
a possibility for five defrost steps. The length of time for
each step is adjustable on the “Defrost Setpoints” screen.
