Section 1 • Installation Recommendations

Proper Wiring Sizing

• Always size wire gauges as specied by the National Electrical Code (NEC) for electronic control devices.

• For improved noise immunity, install one size larger

wire gauge than the NEC requirement to assure ample current-carrying capability.

• Never under size wire gauges.

Voltage Source

• Transformers block a large percentage of Electromagnetic Interference (EMI). It is recom-

mended that the Vilter MicroVission should be isolated with its own control transformer for the most

reliable operation. See Figure 1-1: MicroVission with

Individual Transformer.

• Avoid connecting MicroVission to breaker panels and central control transformers if possible as the

MicroVission is exposed to large amounts of EMI

emitted from the other devices connected to the sec-

ondary terminals of the transformer. See Figure 1-2:

EMI and MicroVission.

Section 1 • Installation Recommendations

Grounding

• Ensure that you run continuous grounds from the utility ground to the MicroVission. See Figure 1-3: Ground Wiring.

• Grounds must be copper or aluminum wire.

• Never use conduit grounds.

Mixing Voltages

• Separate different voltages from each other and separate AC from DC, see Figure 1-4: Mixed Voltage Wiring.

• Each voltage level must be run in separate conduit:

o 460 VAC

o 230 VAC

o 120 VAC

o 24 VAC

o DC Signals

• If your installation site has wireways or conduit trays, you must install dividers between the different voltages.

DC signals

• If your installation site has wireways or conduit trays, you must install dividers between the different voltages.

Section 1 • Installation Recommendations

Best Practices

• Do:

• Keep AC wires away from circuit boards.

• Always run conduit into the bottom or sides of an enclosure.

• Use a water-tight conduit tting to keep water from entering the enclosure, if the conduit must be placed

in the top of an enclosure.

• The MicroVission is supplied with pre-punched conduit holes for your use.

• Don’t:

• Do not run wires through the MicroVission enclosure that are not related to the compressor control.

• Do not add relays, timers, transformers, etc. In the MicroVission enclosure without rst checking with VilterTM.

• Do not run conduit into the top of an enclosure.

• Do not run refrigerant tubing inside the enclosure.

• Do not drill metal enclosures without taking proper precautions to protect circuit boards from damage.

Transformer, Fusing and UPS Sizing

The following information can be used to help determine the power requirements for a MicroVission panel. This information can be helpful for sizing transformers or UPS devices that will power the MicroVission panel.

• The MicroVission panel contains a single power supply

(1) 24VDC @ 4.5 A (108 watts)

• The DC loads that are attached to the power supply are divided approximately as follows;

1. Each press transducer +24VDC @ 30 mA each (x4) = 120 mA

2. Each RTD (negligible), (the hardware applies a 25 mA pulsed signal, which is not constant).

For estimating purposes, assume:

A total sum constant draw for total RTDs used 50 mA

3. Each 4-20mA transmitter for an RTD = 10 mA

• So, for 120V fusing – consider 110 watts for the power supply, PLUS add any additional 120V loads that are con-

nected to the digital outputs + relays added to the panel.

1. Each unloader solenoid = 0.125 amps AC load

2. Each small solenoid = 50 watts (estimate – read the nameplate for exact load rating)

3. Large solenoids (water, hot gas) = 100 watts (estimate– read nameplate for exact load rating)

4. Each small pilot relay = 25 watts (estimate– read the nameplate for exact load rating)

5. Add load values for panel heaters if used, and heat trace tape if used

Section 2 • Hardware Architecture

Overview

The MicroVission control panel utilizes the ARM PC tech-

nology with a Linux operating system. For hardware architecture, see Figure 2-1.

The MicroVission has the following attributes

• Low power, Industrial rated ARM CPU

• 10” XGA, high resolution LCD display. (Outdoor view- able LCD optional)

• 8-wire touch screen operator interface

• Flexible and expandable I/O

• NEMA-4 enclosure (NEMA-4X optional)

• Industrial temperature range design

Figure 2-1. Hardware Architecture Overview

Multi-I/O (Input/Output) Board

This section explains about the Multi-IO board con-

taining Digital Input/Output and Analog Input/Output signals.

The Multi-IO board converts signals generated by the MicroVission program into 120VAC signals as well as detect external 120VAC inputs to signal the MicroVission program. All the signals shown by connectors 1, 2, 3 and 4 are digital, in that there are only two states available either ON or OFF. See board layout, Figure 2-2.

The Multi-IO board converts the varying DC signals into a signal that the MicroVission program can interpret. The signals are considered analog because the input DC signal can vary from the minimum value to the maximum value. All the signals shown by connectors 6, 7, 8, 9 and 10 are analog inputs. This board can also convert signals from the MicroVission program into a current ranging from 4mA to 20mA. These are called analog outputs and shown by connectors 12 and 13. For more information about the board layout see Figure 2-2.

Oil Return Solenoid Output

• When state of Low Oil Level Digital Input is found Active Low, this output is energized. When state of Low Oil Level Digital Input is changed to Active High from Active Low state, this output will be deenergized only once Oil Recovery Solenoid Shutoff Delay Timer is Lapsed.

Unloader (#1 to #4) Output

• These outputs are active only when the compressor is running. When the MicroVission determines that

the compressor should increase or decrease capac-

ity, these outputs will get de-energized or energized respectively in specic sequence as per Compressor Type set in Conguration screen. See Appendix A,

Unloaders section for more details.

MicroVission Controller • Operation and Service Manual • Emerson • 35391MV 1.0

Trip Output

• This output is energized when the system has no Trips. If a trip is issued, the output de-energizes and stays de-energized until the trip condition is cleared.

Oil Crank Case Heater Output

• This output is active and energized when the oil temperature is lower than the oil temperature set-

point. It is de-energized when the oil temperature is higher than the oil temperature setpoint.

Compressor Start Output

• When the MicroVission signals the compressor to start, this output is energized. When the MicroVission signals the compressor to stop, this output is de-energized.

Section 2 • Hardware Architecture

Remote Ready Output

• This output is energized when the MicroVission panel is enabled for remote control. If the compres-

sor parameter does not satisfy start conditions or is

placed into the manual stop position, this output is

de-energized.

Setpoint 1/2 Input

• This input will be monitored when the MicroVission panel is enabled for remote control. When this input

is de-energized, the MicroVission will use Setpoint 1 as Control Setpoint for modulating the compressor capacity. When this input is energized, the

MicroVission will use Setpoint 2 as Control Setpoint

for modulating the compressor capacity. For using

Setpoint 2, the operator should make sure that No.

of Controllers is set to 2 in Conguration screen.

Remote Decrease Input

• This input will be monitored when the MicroVission panel is enabled for remote control. When this input

is energized, the MicroVission will unload compressor by one step.

Remote Increase Input

• This input will be monitored when the MicroVission panel is enabled for remote control. When this input

is energized, the MicroVission will load compressor by one step.

Remote Start/Stop Input

• This input will be monitored when the MicroVission panel is enabled for remote control or if Run Permissive option is enabled. When this input is en-

ergized, the compressor will be allowed to start in selected run mode. If the compressor is running and this input is found de-energized, the compressor will

be stopped and the compressor will have to wait for

next start until this input gets energized.

Low Oil Level Input

• This input must be energized for the compressor to operate. If this input gets de-energized, the com-

pressor will be stopped and issue a Low Oil Level trip provided Oil Level Trip option is enabled in

Conguration screen.

High Level Shutdown Input:

• The MicroVission monitors this digital input to check whether the power is removed from the input

module during compressor start. This input must be energized for the compressor to operate. If deenergized, the compressor will shut down and issue a High Level Shutdown trip.

Compressor Motor Starter Auxiliary Input:

• This input looks for a feedback signal from the compressor starter, conrming that the compressor starter is energized.

Section 5 • Compressor Control

Overview

The Compressor Control screens is where an operator

can set majority of the compressor settings. These settings dene how the compressor will operate and respond to changing loads. The compressor control screen consists of several pages, but in order not to overwhelm the operator with options, many of the pages may not

be visible.

NOTE

How the compressor is setup in the conguration screen will determine what compressor control pages are

displayed.

It is important to note that there isn’t one correct way to set these parameters. Every application is different and requires the operator to tune these settings to achieve

the best operation.

For Suction Pressure Control, Process Temperature

Control & Discharge Pressure Control operator can use

two different set of values for compressor control. These

values are categorized as Setpoint 1 and Setpoint 2.

Active Control Mode decides which set of values will be used to control the compressors.

How Compressor Control Setpoint works?

The MicroVission will load and unload reciprocating compressor cylinders to maintain the control setpoint.

The control setpoint can be either of suction pressure control setpoint, process temperature control setpoint

or discharge pressure control setpoint depending on

what the operator has selected as the control mode.

The following gure shows how the MicroVission uses

the setpoints and offset values to load / unload compres-

Section 5 • Compressor Control

Suction Pressure Control

When the Active Control Mode is set to “Suction Pressure SP1” or “Suction Pressure SP2”’, the control setpoint is

Suction Pressure Control.

Pressure Control Setpoint

The suction pressure of the compressor to operate when

the compressor is running in Auto, Remote Auto, or

Direct I/O Auto run mode.

Load Offset

The offset value when added to the “Pressure Control” setpoint, determines the suction pressure for loading

the compressor.

Load Interval

The time interval for which control algorithm will wait between the steps while loading the compressor.

When the suction pressure of the compressor is equal to or greater than the “Pressure Control” setpoint plus the “Load Offset” value, the control algorithm loads one step

and then waits for the load interval time. Once the load

interval time is lapsed, the control algorithm will again

check if the suction pressure is equal to or greater than the “Pressure Control” setpoint plus the “Load Offset” value. If yes, MicroVission loads the next step.

Unload Offset

The offset value when removed from the “Pressure

Control” setpoint, determines the suction pressure for

unloading the compressor.

Unload Interval

The time interval for which control algorithm will wait between the steps while unloading the compressor.

When the suction pressure of the compressor is less than

or equal to the “Pressure Control” setpoint minus the “Unload Offset” value, the control algorithm unloads

one step and then waits for the unload interval time. Once the unload interval time is lapsed, the control al-

gorithm will again check if the suction pressure is less than or equal to the “Pressure Control” setpoint minus the “Unload Offset” value. If yes, MicroVission unloads

the next step.

Auto Cycle

The auto-cycle setpoints dene the control points in which the compressor will automatically cycle on and off when placed into “Auto” run mode. These setpoints can be “enabled” or “disabled” using the check box. The auto-cycle function will operate only in local “Auto” mode and Direct I/O “Remote Auto” mode. If the auto cycle feature is enabled while running in any other remote mode, the function will simply be ignored.

Auto Cycle Suction Pressure

• Enable: Enables the Auto cycle control. Uncheck

the box to disable the Auto cycle setpoints.

• Start Pressure: When the suction pressure is equal to or greater than this setpoint, the compressor will

start.

• Start Delay: Before the compressor start, there is a

delay for the set time to ensure that suction pressure remains equal to or greater than the “Start

Pressure”.

• Stop Pressure: When the suction pressure is less

than or equal to this setpoint, the compressor will

stop.

• Stop Delay: Before the compressor stop, there is

a delay for the set time to ensure that the suction pressure remains less than or equal to the “Stop

Pressure”.

Auto Cycle Process Temperature

• Enable: Enables the Auto cycle control. Uncheck

the box to disable the Auto cycle setpoints.

• Start Temperature: When the process temperature

is equal to or greater than this setpoint, the compressor will start.

• Start Delay: Before the compressor start, there is a

delay for the set time to ensure that process temperature remains equal to or greater than the “Start

Temperature”.

• Stop Pressure: When the process temperature is

less than or equal to this setpoint, the compressor

will stop.

• Stop Delay: Before the compressor stop, there is

a delay for the set time to ensure that the process temperature remains less than or equal to the “Stop

Temperature”.

Active Control Mode

This drop-down box gives the operator the ability to change the type of Active Control Mode such as Succion Pressure, Process Temperature or Discharge Pressure.

The operator can also switch from Setpoint 1 (SP1) and Setpoint 2 (SP2) for each control method. The options

for drop-down box will depend on the number and type of control selected in the conguration screen.

Load Limiting

The stop load and force unload feature’s primary purpose is an attempt to prevent the compressor from trip-

ping off due to instrument reading. For example, if the suction pressure drops very low, the compressor will trip off for safety reasons. However, the stop load and force unload algorithm recognizes the potential trip and either stops the compressor from loading up or even unloads the compressor step-by-step to prevent the trip.

I/O Based Setpoint Control

This checkbox when enabled, monitors the Remote

Setpoint #1/#2 Digital Input (10th Digital Channel on Multi IO Board). When Compressor is running in Auto /

Remote(Auto) run mode, the selection of Active Control Setpoint depends upon the state of Remote Setpoint

#1/#2 Digital Input. When Remote Setpoint #1/#2 Digital Input is Energized, Active Control Mode will be Setpoint 2. When Remote Setpoint #1/#2 Digital Input is De-Energized, Active Control Mode will be Setpoint 1.

NOTE

This checkbox will be displayed only when “Direct I/O” is

disabled in Conguration Screen.

Stop Load Setpoints

High Suction Pressure

• When the suction pressure value is equal to or greater than this setpoint, algorithm will not allow loading of the compressor. However, if the suction pressure value drops below this setpoint, algorithm will allow loading of the compressor.

High Discharge Pressure

• When the discharge pressure value is equal to or greater than this setpoint, algorithm will not allow loading of the compressor. However, if the discharge pressure value drops below this setpoint, algorithm will allow loading of the compressor.

Section 5 • Compressor Control

Low Suction Pressure

• When the suction pressure value is equal to or less than this setpoint, algorithm will not allow loading

of the compressor. However, if the suction pressure

value exceeds this setpoint, algorithm will allow loading of the compressor.

High Motor Current

• When the motor current value is equal to or greater than this setpoint, algorithm will not allow loading

of the compressor. However, if the motor current

value drops below this setpoint, algorithm will allow loading of the compressor.

Force Unload Setpoints

High Suction Pressure

• When the suction pressure value is equal to or greater than this setpoint, algorithm will unload the compressor by one step. Algorithm will continue unloading the compressor step-by-step to minimum load

until the suction pressure value drops below this setpoint.

High Discharge Pressure

• When the discharge pressure value is equal to or greater than this setpoint, algorithm will unload the compressor by one step. Algorithm will continue unloading the compressor step-by-step to minimum load until the discharge pressure value drops below

this setpoint.

Low Suction Pressure

• When the suction pressure value is equal to or less than this setpoint, algorithm will unload the compressor by one step. Algorithm will continue unloading the compressor step-by-step to minimum

load until the suction pressure value exceeds this setpoint.

High Motor Current

• When the motor current value is equal to or greater than this setpoint, algorithm will unload the compressor by one step. Algorithm will continue unloading the compressor step-by-step to minimum

load until the motor current value drops below this setpoint.

Unload Timer

• This is the time duration that force unload algorithm will use while unloading each step during

the force unload condition. For example, when the

suction pressure value is equal to or greater than the “High Suction Pressure” Force Unload setpoint, the algorithm will unload one step and wait for the time as dened by this setpoint. Once the time set is lapsed, the algorithm will check again if the suction pressure value is equal to or greater than the “High Suction Pressure” Force Unload setpoint. If yes, the algorithm will unload one more step.

Oil Control

This setpoint denes how the MicroVission will manage

the crankcase’s oil. When the compressor is used in cold climatic conditions, it might be possible that compressor does not start due to low crankcase oil temperature.

Oil Crankcase Heater Temperature

• When the oil temperature falls below this setpoint,

the oil heater (7th Digital Channel on Multi IO Board)

will turn ON. Note, there is a 2°F differential associated with this setpoint. For example, when set at 100 °F, the oil heater will turn ON at 98 °F and turn OFF at 102 °F.

Section 6 • Alarms and Trips

Overview

The Alarms and Trips screen provides the options to view

and adjust settings for compressor safety and alarm settings.

Warnings

The MicroVission uses Warnings to notify the operator of the parameters that might inhibit the compressor when started. Warnings are monitored only when compressor is not running. Unless other specied, Warnings use alarm setpoints for detection and message generation. The Warning condition occurs when the value of a parameter drops below or rises above the congured alarm setpoint when the compressor is not running.

All warning messages can be collectively seen in a popup window. This pop-up is displayed when a warning

condition is present and the bottom status bar is pressed.

When the warning condition earlier present is cleared or not anymore present, the corresponding warning message will be automatically removed from bottom status

bar.

Alarms

The MicroVission uses Alarms to notify the operator of running parameters that if left unchecked could result in the compressor shutting down due to a trip. Alarms are only active when compressor is running. The Alarm con-

dition occurs if the value of a parameter drops below or

rises above the congured Alarm setpoint for a continuous delay time (default 5 seconds).

Alarms are shown in a Yellow color banner

on the top and the bottom status bars

Trips

Trips are the conditions that exceed the safety limits of the compressor or refrigeration system and stops the compressor. Trips are only active when compressor is running. The Trip condition occurs if the value of a parameter drops below or rises above the congured Trip setpoint for continuous delay time (default 5 seconds). During Trip condition, compressor run mode will get changed to idle from running.

Warnings are shown in an Orange color banner

on the bottom status bar

Inhibits

The MicroVission uses start Inhibits to prevent the com-

pressor from starting to protect the compressor and the refrigeration system. Inhibits are only active during PreStart condition. While starting the compressor, inhibits are checked rst before the motor is started. Failed start due to an inhibit do not count toward any of the anti-recycle timer including Hot Starts. Unless other specied,

inhibits use alarm setpoints to abort compressor start

and message generation. The Inhibit condition occurs if

the value of a parameter drops below or rises above the

congured alarm setpoint during the compressor start.

Inhibits are shown in a Red color banner

on the top and bottom status bars

Trips are shown in a Red color banner

on the top and bottom status bars

NOTE

When more than one safety condition is active/present, Safety message for each condition (Except Warning) will

get displayed on Top Status Bar in rotating manner.

Freeze Screens

Trips also trigger the input/output screen to take snapshot of all input and output values as Freeze 1 screen.

The Freeze screens are very useful as a troubleshooting

tool for the operator. Refer to Input/Output States sec-

tion for a typical Freeze Data (Trip) screen.

Logging – Event List

All Inhibits, Alarm and Trip conditions are logged in the Event List so the operator can get the complete operational history. The operator can access the Event List

from the Menu screen.

Section 7• Timers

Overview

The Timers screen allows the operator to view and adjust

timer settings associated with the compressor operation. There are different types of timers that the opera-

tor should be aware of listed below. For Timers Screen

pages, see Figures 7-1 & 7-2.

Changeover

The changeover timers will change from one type control to another once the compressor has started and then the time has expired.

Bypass

The bypass timers prevent certain alarm and trip checks from occurring until the compressor has started and

then the time has expired.

Timer Setpoints

Following are the setpoints that the operator can congure on MicroVission.

Load Increase Start Delay

At compressor startup, the compressor capacity will be

at minimum load for this time. This is to allow compres-

sor and system conditions to stabilize. After this timer expires, the system modulates the compressor capacity according to the system demands.

Compressor Interlock Bypass

Once the MicroVission has sent a command to the com-

pressor starter to start, it expects the return signal. This timer denes how much time to wait for that signal before setting a trip condition.

Delays

The delay timers require the condition to occur for the specied amount of time.

Timers

A general timer requiring the time to be expire before

the listed event can occur.

Low Oil Pressure Diff. Bypass

This is the time for which the “Low Oil Pressure” safety

setpoints will remain inactive. After the timer has ex-

pired, the “Low Oil Pressure” safety setpoints will become active and safeties related to “Low Oil Pressure” will get monitored.

Section 7 • Timers

Low Crankcase Oil Temperature Changeover

This is the time for which the “Low Crankcase Oil Temperature – Start” safety setpoints will remain active. After the timer has expired, the “Low Crankcase Oil Temperature – Start” safety setpoints will become inactive and the “Low Crankcase Oil Temperature – Run” safety setpoints will become active.

High Discharge Temperature Bypass

This is the time for which the “High Discharge Temperature” safety setpoints will remain inactive. After the timer has expired, the “High Discharge Temperature” safety setpoints will become active and safeties related to “High Discharge Temperature” will get monitored.

High F ilter Diff. Pressure Changeover

This is the time for which the “High Filter Diff. Pressure – Start” safety setpoints will remain active. After the timer has expired, the “High Filter Diff. Pressure – Start” safety setpoints will become inactive and the “High Filter Diff. Pressure – Run” safety setpoints will become active.

High Motor Amps Bypass

Starting motors can typically pull much more than current than its rated full load amps for a short time. This

timer ignores that sudden inrush of current for the specied time.

Communication Failure Detect Timer

This timer forces the compressor to wait for the set time

before displaying “Remote Comm Timeout” Alarm or “Remote Comm Time-out” Trip when there is no remote communication to MicroVission for the congured time.

True Anti-Recycle Timer

Once the compressor turns off, this timer will keep the compressor OFF for the time set in this setpoint. This

timer is used to prevent short cycling of the compressor.

NOTE

The operator will be able to modify True Anti-Recycle Timer setpoint only if “True” option is set for Anti-

Recycle setting in the Conguration screen.

MicroVission Controller • Operation and Service Manual • Emerson • 35391MV 1.0

Section 7• Timers

Accumulative Anti-Recycle Timer

This timer forces a specied time between the consecutive compressor starts. When the compressor starts,

this timer resets the time and starts accumulating the running time. Once the compressor shuts down, it will

not be allowed to restart for the remainder of time left

on the Accumulative Anti-Recycle Timer. Unlike the True Anti-Recycle Timer, if the compressor has run for the entire time of the Accumulative Anti- Recycle Timer and

then if compressor shuts down, the compressor will be

allowed to restart immediately.

The operator will be able to modify Accumulative AntiRecycle Timer setpoint only if “Accumulative” option is

set for Anti-Recycle setting in the Conguration screen.

Hot Starts per Hour

This counter will count the number of compressor starts

in an hour. This counter will reset only when the time

between two compressor starts is at least an hour. If in an hour’s time, counter reaches to its set value, then the compressor will not be allowed to start until an hour is complete from the time when the counter was last reset. This counter allows consecutive compressor starts,

but once the counter reaches to the set value, it requires

a one-hour window between compressor starts for the counter to reset.

NOTE

Oil Recovery Solenoid Shutoff Delay

This is the time for which Oil Recovery Solenoid Digital

Output will remain ON when the state of Low Oil Level

Digital Input is changed from Active Low to Active High. When this timer expires, the state of Oil Recovery Solenoid Digital Output will change to OFF.

Low Oil Level Alarm Delay

This is time for which “Low Oil Level Alarm” will not be generated once “Low Oil Level” Digital Input is found Active Low. If state of “Low Oil Level” Digital Input remains Active Low continuously for this time, then alarm condition will be generated and “Low Oil Level Alarm” message will be displayed on the Main screen.

Low Oil Level Trip Delay

This is time for which “Low Oil Level Trip” will not be generated once “Low Oil Level” Digital Input is found Active Low. If state of “Low Oil Level” Digital Input remains Active Low continuously for this time, then trip condition will be generated and “Low Oil Level Trip” message will be displayed on the Main screen.

NOTE

The operator will be able to detect and see “Low Oil Level Trip” message on Main screen only if “Oil Level Trip”

checkbox is Enabled in the Conguration screen

NOTE

The operator will be able to modify Hot Starts per Hour setpoint only if “Hot Starts” option is set for Anti-Recycle

setting in the Conguration screen.

Section 8 • Instruments Calibration

Overview

The Instrument Calibration screen allows the operator

to dene how the MicroVission will interpret the signal from any devices connected to panel’s analog inputs. The Instrument Calibration screen is organized in four pages. Each page is then divided into individual tabs for every device.

I/O

Each tab has this section that provides basic information for that device.

A/D bit Value

This eld displays the actual value read by MicroVission analog to digital convertors. This value is unaffected by any changes to the calibrations settings. If a device is

connected to the associated input, there will be some

value displayed in this eld.

Calibrated Value

This eld displays the calibrated value which is the result

of the calibration process. Calibrated value for Pressure

& Temperature values will be displayed in pressure / temperature unit as congured in Conguration Screen.

All instruments are calibrated using a two-point linear calibration process. Any device that has a non-linear re-

sponse to environmental stimuli will not be able to be

calibrated through the MicroVission.

Pressure & Temperature Inputs

The most commonly used Instruments are pressure and temperature sensors. The rst two pages of the

Instrument Calibration Screen are dedicated to these

Instruments; see Figure 8-1 up to Figure 8-12.

Each tab on these two pages are divided into two sec-

tions, Device Calibration and Channel Calibration.

Devices Calibration

The Device Calibration section is where the operation

parameters of the Instrument are dened.

Default Devices

By selecting this option, the operator will have access

to several common devices via a drop-down list. The

devices are predened and if one is selected, then all

the setpoints will be set for the operator.

Custom Device

This option allows the operator to choose the minimum

and maximum value of the Instrument being used.

The Instrument Calibration screen provides a set of rang-

es for default devices. You must select an appropriate

range to calibrate the sensor. If you do not nd a correct range, you can specify the custom range.

Based on the calibration range that you select or specify, the MicroVission displays the calibrated value. This calibrated value of the respective analog input is also shown

on the Main screen.

Channel Calibration

The Channel Calibration section denes the type of signal sent by the Instrument.

Offset

Once the two-point calibration is completed, it is com-

mon for a small error to exist. By entering the value of

the error from the calibrated value and the actual value

into the “Adjustment” entry box, that error will be added/subtracted from the “Total Offset”. The offset is ap-

plied to the calibrated value which should correct the error.

Range

This option is available when the “Custom Device” option is selected. Here the operator denes the signal type and range transmitted by the Instrument. The operator can select from several predened ranges in the

drop-down list or enter a value.

Analog Inputs

Page 3 of Instrument Calibration Screen is dedicated to

instruments used for Motor Current and Process Control.

Motor Current

The MicroVission measures the motor current value us-

ing the 4-20 mA signal transmitted from the external

device.

The calibration process for Motor Current is slightly different from all other calibration procedures. The motor current must be calibrated while the compressor

is running at close to full amps as much as possible. In addition, the operator will need a value into the “Enter Desired Value” entry box that is equal to the measured value in amps by a calibrating measurement device. After entering the measured value, the displayed motor current in “Calibrated Value” eld may still be off slightly. In this case re-enter the desired value and the displayed value should get progressively closer.

4-20mA Scale

• 4mA: Not editable by the operator. Denes the minimum value in Amps represented by 4mA input..

• 20mA: Denes the maximum value in Amps that represented by 20mA input.

• Enter Desired Value: The operator enters the correct

current value. Each entry will re-calculate the point

slope calculations of the current calibration.

• Total Error: Not editable by the operator. Displays

the total error offset of the value from the “Enter

Desired Value” setpoint.

Process Temperature or Pressure

The Process Control tab on this page will display either Process Temperature or Process Pressure depending on the “Process Control” type selected by the operator in the Conguration screen. For more information, see Conguration section.

The tab is divided into two sections, Device Calibration and Channel Calibration with Default Devices and

Custom Device as well as Offset and Range Calibration

features as described for the standard Pressure and Temperature Inputs.

Section 8 • Instruments Calibration

Auxiliary Inputs

Page 4 of the Calibration screen allows the operator to dene the parameters of an installed auxiliary analog instrument. These instruments are usually not part of a typical compressor set-up but MicroVission provides a way for the operator to add additional capabilities. The layout of this screen is typical to the pressure and tem-

perature calibration screens.

Device Calibration

These setpoints allow the operator to dene what the input from the auxiliary instrument means in terms of unit and range. If a temperature measuring instrument is

connected, then the operator would select temperature

from the “Units” dropdown box then set the minimum

and maximum value for the scale.

Channel Calibration

The Channel Calibration section denes the type of signal sent by the Instrument.

• Offset: Once the two-point calibration is complet-

ed, it is common for a small error to exist. By entering the value of the error from the calibrated value and the actual value into the “Adjustment” entry

box, that error will be added/subtracted from the

“Total Offset”. The offset is applied to the calibrated

value which should correct the error.

• Range: Here the operator denes the signal type

and range transmitted by the Instrument. The operator can select from several predened ranges in

the drop-down list or enter a value.

Section 9 • Event List

Overview

The Event List screen is designed to display the list of all compressor events are arranged in chronological order with the latest event appearing at the top. The infor-

mation available on the screen helps operator to understand the operation of the compressor and trouble-

shooting. This screen is divided into four columns and

can list up to 128 separate events. The operator can also

download the information on the event list through the

Data Backup Screen.

Event List Columns

• Date: Displays the date of the event in MM/DD/

YYYY format.

• Time: Displays the time of the event in HH:MM:SS format. The time data displays AM/PM information when 12-hour format is congured in the Conguration screen.

• Event Type: Displays the type of message for a listing. The common event types are “Start”, “Stop”, “Trip”, “Inhibit”, “Alarm”, “Info”, and “System”.

These helps the operator to understand the mean-

ing of the “Message” column.

• Message: The information that describes the event.

The operator can use “Update” button to refresh the

event list data when this screen is open, instead of exit-

ing the screen and re-entering to see the latest events

data.

Section 10 • Input / Output States Screen

Overview

This screen displays “Live Data” of all the Analog Inputs / Outputs and Digital Inputs / Outputs being monitored. There are two pages of Inputs / Outputs (I/O) available for viewing, see Figures 10-1 & 10-2.

This screen also takes a snapshot of all the I/O points

when the operator presses on “Freeze Data” button or if

the compressor experiences a trip condition. The Freeze

page displays the title that indicates whether the Freeze data is saved due to trip condition or “Freeze Data” button was pressed by the operator, see Figures 10-3 & 10-

4. Latest Freeze data is shown in Freeze 1 tab. Up to ve Freeze pages can be saved. The oldest Freeze page will be removed when more than ve Freeze events occur.

These freeze events can be downloaded to a USB drive

through Data Backup screen.

NOTE

The format in which time is displayed on the Freeze page does not change depending on time format selected in the Conguration screen. Also values for Auxiliary Analog Inputs like Discharge 2 Pressure & Discharge 2 Temperature will be only shown when Analog Input 1 Board is enabled from the Conguration screen, see

Section 11 • User Access

Overview

The User Access is the screen where all operators go to log in.

In the MicroVission, each screen has a security level that provides the necessary permissions to the operator, technicians and/or supervisors to modify different sets of setpoints. The MicroVission has four levels of security, see Figure 11-1.

• Level 0 – This is the default level where no operator is logged in. The functions available to the operator are very limited and basically only allows them to start

and stop the compressor.

• Level 1 – This is a technician level of access. All the setpoints needed to operate and adjust the performance of the compressor will be available to an operator with this level of access.

• Level 2 – This is a supervisor level of access. Setpoints

that require a higher level of knowledge such as calibrating instrument will be available to an operator

with this level of access.

• Level 3 – This is considered a contractor level of ac- cess. The setpoints available at this level have the

most potential of causing damage to the compressor. Therefore, this access is restricted to those only with the highest level of competence.

The User Access screen also provides options to add new

operators and modify or delete existing operators. Any operator can add an additional operator but can only add operator of lesser or equal security level.

The MicroVission will be shipped with a Level 3 operator

and password pre-assigned to the installing contractor. The contractor can then assign all users with security lev-

els as needed.

The procedure to assign user access levels is to rst press

the User Access button. The User Access screen will ap-

pear with the preassigned level 3 operator name visible within the “Operators” section. Highlight the name,

then enter the password associated with that name of

the user, then press Enter key to close the keyboard. Then press the “Apply” button. Press the “Manage Accounts” tab to begin the process of entering another Operator name, and assigning password and user level of this additional user. Lastly – remember to press the “Add/Update” button to add this user to the list, then press the “Apply” button before exiting this screen to make this change permanent.

• The operator should set appropriate setting as per the compressor connected. This setting informs the control program to properly process the number of analog channels for your compressor. For instance, if 12 or 16 cylinders is selected, then the control program processes a second discharge pressure safety and second discharge temperature safety.

No. of Unloaders

• The operator should set appropriate setting as per the compressor connected. This setting informs the control program to control unloader digital outputs which in turn modulates the capacity of compressor in steps. Each setting option displays the number of unloaders and the unload percentage steps for the compressor. This setting is based on “No. of Cylinders”. For more information about Unloaders,

see Appendix: Unloaders.

Section 12 • Configuration Screen

Compressor Control Section

Vilter compressors typically run in one of the three control modes: Suction Pressure Control, Process Control or

Discharge Pressure Control. Discharge Pressure Control is mutually exclusive with Suction Pressure Control & Process Control. When Discharge Pressure Control is se-

lected, Suction Pressure Control & Process Control are

grayed out and cannot be selected. Similarly, if Suction

Pressure Control and/or Process Control is selected,

Discharge Pressure Control is grayed out and cannot be

selected.

• Suction Pressure Control: This denes the Suction

Pressure input as the process variable and all controls will be based on Suction Pressure. The operator has the option to select up to two controllers where each can have its own set of setpoints.

• Process Control: This denes the Process Control

input as the process variable and all controls will be based on either Process Temperature or Process Pressure. The operator has the option to select up to two controllers where each can have its own set of setpoints. The operator has to select one of the process control modes, either temperature or pressure as a process variable. Temperature and Pressure op-

tions are mutually exclusive.

• Discharge Pressure Control: This denes the Discharge Pressure input as the process variable and all controls will be based on Discharge Pressure. The

operator has the option to select up to two controllers where each can have its own set of setpoints.

Oil Monitoring

This section provides the options to monitor the Oil

Filter related Analog Inputs. The operator will be able to set any of one option related to Oil Filter from below

three options:

• No Oil Filter Monitoring: When this option is selected, Filter Inlet Pressure & Filter Outlet Pressure

inputs will not get monitored. Oil Filter Differential Pressure will not get calculated. Safeties related to “High Filter Differential Pressure” will not be active.

• Only Oil Filter In: When this option is selected, Only Filter Inlet Pressure input will get monitored while Filter Outlet Pressure input will not get monitored. Oil Filter Differential Pressure will get calculated as

Filter Inlet Pressure minus Oil Manifold Pressure.

Safeties related to “High Filter Differential Pressure”

will be active and monitored.

• Oil Filter In and Oil Filter Out: When this option is selected, both Filter Inlet Pressure input &

Filter Outlet Pressure will get monitored. Oil Filter Differential Pressure will get calculated as Filter

Inlet Pressure minus Filter Outlet Pressure. Safeties

related to “High Filter Differential Pressure” will be active and monitoredBased on the option you select for oil monitoring, the MicroVission Controller displays the warning and trip message for the low oil lter pressure.

You can also select an option to trip the compressor if

the oil level drops below the required level.

12 – 2

Oil Level Trip

This checkbox when enabled, allows the operator to

monitor “Low Oil Level Trip”. When this option is enabled, MicroVission program will monitor state of “Low Oil Level” Digital Input. The digital input will be low when compressor oil level drops below the minimum required level. For more information on monitoring related to

safeties, see Timers section.

Touch Screen

The “Calibrate” button puts the screen into calibration mode. Calibration of the touchscreen is only required if the operator nds that the pointer’s arrow is not following the nger while trying to operate on the MicroVis-

sion screens. In calibration mode, the operator needs to touch the

pointers as shown on the screen starting with the topleft corner. After touching the pointer, next pointer will

be shown. The operator need to touch on all four point-

ers shown on corners of the screen in the given sequence

to complete the calibration.

Section 12 • Configuration Screen

Anti-Recycle

Anti-Recycle denes the method of motor protection

due to repeated motor starts. The operator has three options for protection:

• Hot Starts: This option will allow only a certain

number of compressor starts in an hour before set-

ting the time to the anti-recycle timer. The number of starts to be allowed is set through the “Hot Starts

per Hour” setpoint of the Timers screen.

• True : This option adds the time to anti-recycle timer once the compressor is shutdown, hence forcing a specic wait time once compressor is stopped and next compressor start. The wait time required is set through the “True Anti-Recycle Timer” setpoint of

the Timers screen. The compressor motor cannot

be started if there is anti-recycle time left.

• Accumulative: This option immediately adds the time to anti-recycle timer once the compressor is started. The time to be added is set through the “Accumulative Anti-Recycle Timer” setpoint of the Timers screen. Unlike the True Anti-Recycle Timer,

if the compressor has run for the entire time of the Accumulative Anti-Recycle Timer and then the compressor stops, the compressor will be allowed to re-

start immediately.

The operator can view anti-recycle time on the Main screen if “Anti-Recycle” option is selected in Congurable Main Screen Settings on Page 4.

Compressor Identication

This section sets the identication for a MicroVission

unit.

• Name: Unique identier that is used for all

MicroVission units.

• Panel ID: Panel Identier used by controller when communicating with multiple panels.

• Order Num: Identies the Order Number of the

purchase of the compressor. This number will be

needed if the operator requires help/support from

the Vilter.

Date and Time

These section sets the date and time of the MicroVission.

Accurate date and time are essential for accurate logging and troubleshooting. Setting these parameters will

set the hardware clock embedded in the MicroVission

CPU. If the time is not retained after powering down the

panel, the operator should check and/or replace the coin

style battery on the panel SBC behind the touchscreen.

• Year: Entry box to set the current year.

• Month: Entry box to set the current month.

• Day: Entry box to set the current date.

• Format: Selection to choose between 24 hours and

12 hours clock.

drop-down box will be available if the 12 hours format is selected.

• Minute: Entry box to set the clock minutes.

• Second: Entry box to set the clock seconds.

VNC Account

MicroVission panels can be accessed remotely by using a

VNC client over TCP/ IP network. This section allows the

operator to change default VNC password and VNC port number. For more information, see Figure 12-2.

• New Password: The operator will add the password

by touching the entry box and typing the password

via the pop-up.

• Verify New Password: The operator will re-enter

the password by touching the entry box and typing the password via the pop-up keyboard.

• Port Number: The operator will change the port number for the VNC server by touching the entry box and typing the port number via pop-up key-

pad. Default port number is 5900. The operator can

assign the port number in the range from 5900 to

6000.

Alarms and Trips

The “Idle Time Trip” checkbox works in conjunction with the “High Level Shutdown” digital input. If checkbox is

enabled, when the compressor is in idle state and this

digital input is off, the compressor should give a trip message.

Direct I/O

Enables the Direct I/O Inputs. When checkbox is en-

abled, the operator can select any one Direct I/O option from “Auto Control” and “(Digital) Manual Control”.

• Auto Control: This option will allow the operator to run compressor in Direct I/O Auto Run Mode. The

algorithm will use setpoints of Compressor Control screen for loading & unloading of compressor cylinders.

• (Digital) Manual Control: This option will allow the operator to run compressor in Direct I/O Manual

Run Mode. The algorithm will monitor the state of “Remote Increase” & “Remote Decrease” Digital Inputs for loading & unloading compressor cylinders respectively. If “Remote Increase” Digital Input is ON & “Remote Decrease” Digital Input is OFF then the compressor will load one step. Similarly, if “Remote Increase” Digital Input is OFF & “Remote Decrease” Digital Input is ON then the compressor will unload

one step.

The operator should ensure following conditions are

met to run the compressor in Direct I/O Run Mode:

1. “Direct I/O” checkbox is enabled

2. “Active Remote Control” setting is set to “Direct I/O”

3. “Remote Start/Stop” Digital Input is ON

Once above conditions are met, the operator can

start compressor in Direct I/O Run mode by pressing on “START” button in Main screen and then selecting “Remote” option in pop-up window.

Communication

The communication section is the control center for all communications to the MicroVission panel. It is possible to have multiple modes of communications enabled and

used. However, only one mode can be used to control

the MicroVission, which would be the one selected in

the “Active Remote Control” drop-down box.

For a complete list of communication registers, see

Appendix B, Communication Table.

This feature of the MicroVission offers the ability to dene how the MicroVission will handle communication

failure.

The operator can select any one options from below two

options:

• Revert to Local Control: Once the compressor

has started running in the Remote Run Mode, the “Communication Failure Detect Timer” as cong-

ured in Timers screen will start. If no further communication with MicroVission takes place for the

congured time, the MicroVission will be placed in Local Auto Mode. MicroVission will also display “Remote Comm Timeout” Alarm Message and add

time-stamped alarm event to Event List screen.

• Stop Compressor with Trip: Once the compressor

has started running in the Remote Run Mode, the “Communication Failure Detect Timer” as cong-

ured in Timers screen will start. If no further communication with MicroVission takes place for the

congured time, the compressor will be stopped due to “Remote Comm Timeout” Trip. MicroVission will also display “Remote Comm Timeout” Trip Message and add time-stamped trip event to Event

List screen.

Section 13 • Data Backup

Overview

The Database Backup screen provides the operator a

way to extract information out of the MicroVission for backup purposes or diagnostics. See Figure 13-1: Data

Backup Screen - Save/Load.

From this screen, the operator can download all the

Setpoint Databases, Maintenance Logs, Event Lists,

Freeze Data, Trend Data and Compressor Run Hours to

a portable USB ash drive. That information can then be

uploaded back to the MicroVission in the case of data

corruption or to update the MicroVission program.

Additionally, this screen also allows the operator to reset all values to the factory defaults.

All the information saved to the USB ash drive is open information, meaning none of the data is encrypted and operator is free to examine it. The log les are all saved

as simple ASCII text and the databases can be examined with SQLite.

Refresh

• The Refresh button is used to initiate a scan of the

USB ports and list any devices found in the “Available

Devices” window.

Save / Load

In this section, operator can either save the MicroVission

setpoints and log information to a USB ash drive or load from a USB ash drive back to the MicroVission.

Save

• Selecting Save allows the operator to save MicroVission data to a USB ash drive using the in-

formation provided on the screen. The button on

the top right side will be labeled “Save” when this is

selected.

Load:

• Selecting Load allows the operator to load data from a USB ash drive to the MicroVission using the information provided on the screen. The button on the top

right side will be labeled “Load” when this is selected.

Section 13 • Data Backup

Factory Reset:

The Factory reset button offers the operator the ability

to reset all the MicroVission setpoints back to the facto-

ry default settings or a specic database. If the operator nds that a screen will not load when selected, it is likely

that the database associated with that screen has been

corrupted. Unfortunately, data corruption is always a possibility in any system. So, this function was designed to help the operator to regain control, see Figure 13-2.

Reset

• This button initiates the process to revert the

MicroVission back to the factory default settings.

Setpoints Report

The setpoints report screen offers the operator ability to generate a setpoints report for all screens. The reports are stored as .csv les and can be saved to a USB drive from Save/Load screen by selecting the “Setpoints Report” option in Data Items section during backup of database. The .csv le can be imported in any spread sheet application. During operation, the operator can generate reports at any time. See Figure 13-3: Data

Section 13 • Data Backup

Database Backup Procedure

Upgrading the program in the MicroVission panel normally involves replacing the SD card. Note that all

compressor operation setpoints, calibration values and maintenance information is stored on the SD card.

So, when upgrading to a new program (new SD card), the task is simplied by using the “Database Backup” and “Database Restore” functions provided in the MicroVission to migrate the database of the original SD

card to the new SD card.

There are three main steps to this process:

1. Backup the database of original SD card (currently

in the MicroVission panel) – onto a thumb drive or ash drive.

2. Replace the original SD card with new SD card.

3. Restore the original database to new SD card.

Backup Database of Original SD Card

It is REQUIRED to manually reenter the Alarms and Trip settings when upgrading from some older version of programs. Therefore, it is highly recommended to create a hardcopy of all compressor operating setpoints, or to create and have handy a printout of the Setpoints Re-

port .csv le. It is also recommended to make a hardcopy of the conguration information and maintenance information prior to changing SD cards. For the list of all the information that you should record, see the “Record operating setpoints and conguration information” section below.

NOTE

1. With the original SD card installed into the MicroVission SBC, insert the ash drive into the USB port. This port is located along the left side of the single board computer above the ethernet connector. See Figure 13-4: SD Replacement.

2. Log into the MicroVission using your username and password (you will need to be Level 3 to upload

data).

3. Navigate to the Data Backup screen.

4. In the “Available Devices” window, you should see

something like “/media/usb0”. If you do not see anything in this window, press the “Refresh” button,

and wait about 5 seconds. After that press the but-

ton again. If you still do not see the device, then the MicroVission does not recognize the ash drive - try a different one. If you do see it, highlight it.

5. Now highlight the “Filename” eld (which will also contain “/media/usb0”). A keyboard will appear. Now type in the name of the le that you want for your database for this compressor. For instance, “cylinders_month_day_year” or something similar for identifying the le to the compressor. Then press “Enter” key on keyboard.

6. Now press the “Save” button. A “watch” icon will appear. Shortly thereafter, a popup box should appear with a message that the save was successful and asking if you want to “unmount” the ash drive device. Press on “Yes” Button. If the “watch” icon re-

mains after a minute or so, then the MicroVission is

unable to close the backup le it has written to the thumb drive. Power down the MicroVission and try

the procedure with a different thumb drive.

The data migration procedure (moving the original SD card database to new SD card) uses a “thumb drive” or “ash drive” to transfer data from the original SD card

to the new SD card. Note there have been a few re-

cords of some thumb drives not being recognized by the MicroVission. If you have difculty in getting the MicroVission to recognize the thumb drive – then try a different one. Vilter has successfully tested many different manufacturers and sizes; a partial list is given below:

o SanDisk micro cruzer 2.0 GB

o Imation 2.0GB

o Kingston DataTraveler 512 MB

o SanDisk mini cruzer 128 MB

Replace Original SD card with New SD card

Now that the database le has been saved to the thumb drive, you can replace the “original” SD card with a new

SD card.

1. Power down the MicroVission.

2. Remove the thumb drive and take out the “original” SD card and install the new one.

3. Label both the old and new card to identify the com- pressor it is for.

Section 13 • Data Backup

Restore Original Database to New SD card

Now that the new card is inserted, power up the MicroVission panel. The MicroVission boots up in a minute or so.

• Once the MicroVission is booted up, press on the

“User Access” button.

• Insert the thumb drive in to the USB port.

• Navigate to the Data Backup screen. You should

again see the USB thumb drive listed in the “Available

Devices” window.

• Select the Load function (above the “Available

Devices” eld), and then highlight the device that is listed in the “Available Devices” window.

• In the “Select Folder/File” window, nd the backup le for this compressor, and highlight it.

• Now press the “Load” button.

a) A pop-up window will appear with a message

Loading new databases will require a program restart. Continue?”. Press “Yes”.

b) Another pop-up window might appear with

a message “One or more settings selected for loading were missing from the archive. And it will list what is missing. Continue loading anyway?”. Press “Yes”.

c) Another pop-up box might appear with a

message asking if you want to use the IP address it found. Press “OK”.

• A pop-up box appears with a message “Settings were successfully loaded. Program will restart”. Press “OK“.

When the OK button is pressed, the panel will reboot.

Now using the “hand documented” settings that you recorded, compare the setpoints on that list against those in the MicroVission. They should all be OK. Here are the

KNOWN issues that we have found with this procedure.

• If you have communication connection issues after

restoring the database, you may have to “re-enter” the IP address that is shown on page 3 of the conguration screen. If you experience problems after the “Restore” function – then re-enter your communication settings.

Appendix B • Communication Tables

MicroVission Communication Table

Scope: MicroVission Programs – version 1.0 .

NOTES:

• All ENUM variables are of INT (Integer) type

• All F-INT data types represent oating point values as INT types multiplied by 10

• All Pressures are in Psig

• All Temperatures are in Fahrenheit

• Modbus TCP addressing is PLC-style (Base 1) addressing

• On Error, Modbus TCP server only returns an error code of “Illegal Data Address”

• All registers returned (INT and F-INT) are 2 bytes long

• For Ethernet/IP, use INT data type and PLC-5 Word Range Read/Write MSG instructions

• Remote commands cannot be issued if the panel is in the “Remote Lock” mode

• Polling rates should not be less than 5 secs

• Writes to the MicroVission should only occur when a value needs to be changed

• Lower Range and Higher Range values mentioned are default values of MicroVission setpoints

• Users can modify Lower Range & Higher Range values from MicroVission Panel and accordingly maintain their own table
