Important Note

Before applying power to the VISSION MicroController panel, all wiring to the panel should be per NEC.
Specifically check for proper voltage and that the neutral is grounded at the source. An equipment ground
should also be run to the panel.

*See W iring Instructions and Diagrams before proceeding.

Before start-up you need to enter all system values and options, see section on Setpoint Values.

“Before powering the Vission control panel down”, it is a good idea to Backup Control Settings to insure
that all previously changed setpoints have been properly saved. See section on saving changes. After back­ing up the setpoints DO NOT power down the V ission panel for at least 1 minute. This will allow adequate
time for all setpoints to be properly saved.

Note: The screen shots depicted in this manual represent the screens corresponding to
Vission program version # 2.4.41, the current version at time of printing. In our effort
to continuously improve the functionality and ease-of-use of the Vission Micro-con­troller, the look of some screens may differ slightly than the representations shown
here.

The Main Screen

Main Screen

This screen has been designed to give
the operator an overall view of all operating
parameters affecting the compressor pack­age. This screen should always be displayed

when maintenance items and setpoint items
are not being performed. The date on the

screen is updated every ½ second. Status
information such as Alarms and Trips are
displayed on the screen.

This Screen contains buttons to navigate
to setpoint, setup and maintenance screens.

Status information on the compressor, oil pump,
oil heater and run mode.

Start/Stop buttons.
Hour meter.
Motor amperage.
Refrigerant.
Real time compressor

and package operating conditions.
Volume and Capacity Slide locations.

From the Main screen, touch the Setup but-
ton. After entering an authorized user name
password, the screen pictured below will ap­pear.

·Operator Name – This is the same list that
appears in the login dialog. Names in this list
can be selected for deletion. To change a
name or password, you delete the name and
enter a new name/password pair. The
VILTER operator name cannot be deleted.
Emergency passwords provided by a Vilter
representative for the VILTER name are
good only on the date for which they are
issued. They are intended to permit navi­gation to this screen for setup or repair of
this list.

Set Up Screen

·Language – The user screens can be seen
in English, French, and Spanish, depend
ing on the option selected. Some text will
still display in English even when another
language is selected.

·Pressure Units – Select units of measure
for pressure readings. Choices are psi, kg
cm2 and kPa. This section only, affects
pressures displayed on main screen. On all
other screens, units are displayed in psi. On
the main screen with psi selected, negative
gauge pressures will display as inches of
mercury vacuum with the unit “Hg. On
other screens, negative numbers are scaled
as “psi”.

·Temperature Units – Select units of mea
sure for temperature. Choices are Fahren
heit or Celsius.

·Refrigerant – The choice R717 (Ammonia).

T ouch Here

23

Set Up Screen

· Anti-Recycle – The operator can select from

the following AntiRecycle options: True, Ac­cumulative, Modified, or Hot Starts. These
select the strategy used to prevent excessive
start/stop cycles of the compressor. Timers
and counters used to enforce anti-recycling
are adjusted and monitored in the Compres­sor Timer Settings screen, reached from the
Menu screen. Help for the Timer Settings
screen explains how the different settings and
strategies operate.

· Compressor Control Via – Operator can

choose the method or mode of compressor
control. This determines which measured vari­able is used in making loading (capacity con­trol) decisions. The choice selected here de­termines which setpoints are made available
for adjustment on the Compressor Control
Setpoints screen.

· Delete Operator – Operator can choose to

delete operator names from the authorized op­erator listing. A name in the list is selected by
touching it. The selected name will be deleted
from the list when this button is pushed. If
you delete all the names (besides VIL TER), be
sure you add at least one before leaving this
screen.

· Add Operator – The button opens a dialog

for entry of a new name/password pair. Noth­ing (leaving the password text box blank) is a
legal password. The password is not ob­scured as it is typed in, so untrusted parties
should not be permitted to view the screen
during entry. The password is not confirmed
with a repeat entry, so verify it visually before
pressing okay. Up to 25 name/password pairs
can be added. The Operator Name list box will
acquire a scroll bar when it fills.

·

Slide Non-Movement – Alarm enable and dis­able buttons permit selecting whether an alarm
should be generated when failure of slides to
move is detected.

· Setpoint #1 Oil Pump #2 Oil Pump – For

single stage and high stage operation, part
time or normal oil pump fuction are used. The
oil pump shuts off after discharge pressure
has risen sufficiently to drive oil injection. Oil
pump operating mode is independently
settable for setpoint groups # 1 and # 2.

· Modbus Slave Network Address – When mul-

tiple MicroControllers are connected on a
Modbus Network, each controller must have
a unique address from the other
MicroControllers on the network. Duplicate
node addresses are not allowed. The node
address of each V ission is determined through
the SETUP menu. The MicroController that
will initiate all conversation on the network
MUST be defined as node 100 (this is defined
as the “master” node). All other node num­bers should be in the range of 101 through

174.

This must be set when the extra special port
(Com4) is used to control or monitor the com­pressor via Modbus. It also must be set when
the multi-compressor sequencing feature is
used. Even though Ethernet is used for the
comms, this address establishes the
compressor’s identity and role in the sequenc­ing logic.

· Reset After Power Fail – When Auto is se-

lected, the compressor will attempt to restart
on powering up if it was running in ‘Auto’
when powered down and enabling conditions
are met. When ‘Manual’ is selected, the com­pressor powers up into the ‘Stop’ mode and
an explicit command to run is required from
an operator or comms channel.

· Min Run Capacity – When enabled, the Mini-

mum Run Capacity setting on the Addition
Compressor Setpoints screen operates as de­scribed in the help for that screen. When
multiple compressor sequencing is used, se­lecting Disable here does not interfere with
use of the Min Run Capacity setting in the se­quencing logic.

24

Log On, Off,or Save Changes

Set Up Screen

Press Log on/Save Button and the above screen will appear. When altering setpoints, log on is necessary. Select
appropriate user name and enter password to change setpoints. This screen is also used to backup and save setpoints
by pressing (Backup Settings).

After performing a “Back up Setting” operation, DO NOT power down the Vission/Vantage panel for atleast 1
minute. This will allow adequate time to insure all setpoints have been properly stored.

Version Screen

T o View if a customized program has been installed in your unit, go to the main screen and press VERSION, a
screen will appear with the program version and the make model of the unit.

25

Maintenance Screen

T ouch Here

From the Main screen touch the Maintenance button.

“Service Item Required” message indicates that the compressor runtime hours has accumulated to a value - or a
point- where service Maintenance is required.

>From the main screen, press the “Maintenance” button. A chart will be shown to indicate what service is required

- based on the number of hours the compressor has run.

After the all required service work has been accomplished, press the “Service” button located on the Maintenance
screen. A “Services Completed” screen will appear. Press on each service that has been completed. A “check” will
appear next to each item that has been pressed. When all required services have been completed, and the appropriate
box has been checked in the “Services Completed” screen, then the “Service Item Required” message will disappear
on the main screen.

Note: All of the service items listed for that interval must be checked before the “Servicing Item Required” message
will disappear.

26

Maintenance Screen

This screen shows the chart of routine maintenance to be performed on the machine at hourly intervals from 200 hours
to 120,000 hours.

The Service Button from the Maintenance Screen will bring you to this screen.
When entering service items that were completed, make sure to check all items that are listed to be done at that

service interval.
