FIG. 1 – MODEL YT MILLENNIUM CHILLER

SYSTEM OPERATION DESCRIPTION (SEE FIG. 2)

The YORK Model YT Millennium Chiller is commonly ap plied to large air conditioning systems, but may be used on other applications. The chiller consists of an open motor mounted to a compressor (with integral speed in creas ing gears) condenser, cooler and vari able ß ow con trol.

The chiller is controlled by a modern state of the art OptiView Control Center that monitors its op er a tion. The Control Center is programmed by the op er a tor to suit job speciÞ cations. Automatic timed start-ups and shut downs are also programmable to suit night time, week ends and holidays. The operating status, tem per a tures, pressures and other information per ti nent to op er a tion of the chiller are automatically dis played and read on a graphic message display. Other displays can be ob served by press ing the keys as labeled on the Con trol Center. The chill er with the OptiView Control Cen ter is applied with an electro-mechanical start er, YORK Solid State Start er (optional) or Variable Speed Drive (optional).

There could be either of two different Solid State Start ers applied. New production chillers are equipped with the Mod “B” Solid State Starter. This starter contains a

COOLER

combination Logic/Trigger Board that interfaces the Con trol Center with a serial communications link. Ear li er vintage chillers, such as those encountered in Con trol Cen ter retroÞ t ap pli ca tions are equipped with the Mod “A” starter. This Start er con tains a Trig ger Board that in ter fac es to a Logic Board that is in stalled inside of the Control Cen ter.

In operation, a liquid (water or brine to be chilled) ß ows through the cooler, where boiling refrigerant absorbs heat from the liquid. The chilled liquid is then piped to fan coil units or other air conditioning terminal units, where it ß ows through Þ nned coils, absorbing heat from the air. The warmed liquid is then returned to the chiller to complete the chilled liquid circuit.

The refrigerant vapor, which is produced by the boil ing action in the cooler, ß ows to the compressor where the rotating impeller increases its pressure and tem per a ture and discharges it into the condenser. Water ß ow ing through the condenser tubes absorbs heat from the re frig er ant va por, causing it to condense. The con dens er water is sup plied to the chiller from an external source, usually a cool ing tower. The condensed re frig er ant drains from the con dens er into the liquid return line, where the vari-

able oriÞ ce meters the ß ow of liquid re frig er ant to the cooler to com plete the refrigerant cir cuit.

The major components of a chiller are selected to han dle the refrigerant, which would be evaporated at full load design conditions. However, most systems will be called upon to deliver full load capacity for only a relatively small part of the time the unit is in operation.

CAPACITY CONTROL

The major components of a chiller are selected for full load capacities, therefore capacity must be controlled to maintain a constant chilled liquid temperature leav ing the cooler. Prerotation vanes (PRV), located at the en trance to the compressor impeller, compensate for vari a tion in load (See Fig. 2, Detail A).

INTRODUCTION

FORM 160.55-O1 (604)

The YORK OptiView Control Center is a mi cro pro ces sor based control system for R-11 or R123 cen trif u gal chillers. It controls the leaving chilled liq uid tem per a ture via pre-rotation vane controls and has the abil i ty to limit motor current via control of the pre-ro ta tion vanes. It is com pat i ble with YORK Sol id State Start er (optional), Variable Speed Drive (op tion al) and Electro-Mechanical starter ap pli ca tions.

The panel comes conÞ gured with a full screen LCD Graphic Display mounted in the middle of a keypad in ter face. The graphic display allows the presentation of several operating parameters at once. In addition, the operator may view a graphical representation of the his tor i cal operation of the chiller as well as the present operation. For the novice user, the locations of various chiller parameters are clearly and intuitively marked. Instructions for speciÞ c operations are provided on many of the screens.

The graphic display also allows information to be rep re sent ed in both English (temperatures in °F and pres sures in PSIA) and Metric (temperatures in °C and pres sures in kPa) mode. The advantages are most ap par ent, however, in the ability to display many languages.

The Control Center continually monitors the system operation and records the cause of any shutdowns (Safe ty, Cycling or Normal). This information is re cord ed in memory and is preserved even through a pow er fail ure condition. The user may recall it for view ing at any time. During operation, the user is con tin u al ly advised of the operating conditions by various sta tus and warn ing messages. In addition, it may be con Þ g ured to notify the user of certain con di tions via alarms. A complete listing of shutdown, status and warning messages is at tached in

the Display Messages section of this book.

There are certain screens, displayed values, pro gram ma ble Setpoints and manual control shown in this book that are for Service Technician use only. They are only

displayed when logged in at SERVICE access level

or higher. The Setpoints and pa ram e ters displayed on these screens are explained in detail in YORK Service

Man u al 160.55-M1. These parameters affect chiller

op er a tion and should NEVER be modiﬁ ed by anyone oth er than a qualiﬁ ed Service Technician. They are shown in this book for reference only.

Advanced Diagnostics and troubleshooting in for ma tion for Service Technicians are included in YORK Service Manual 160.55-M1. Also included in the Service man u al are detailed descriptions of chiller features, such as the Refrigerant Level Control (Future), Purge sys tem, Hot Gas By pass, Remote Setpoints and Smart Freeze Pro tec tion.

The control center expands the capabilities of re mote control and communications. By providing a com mon networking protocol through the ISN GPIC YORK Chill ers not only work well in di vid u al ly, but also as a team. This new protocol allows in creased remote con trol of the chiller, as well as 24-hour performance mon i tor ing via a remote site. In ad di tion, compatibility is main tained with the present net work of ISN com mu ni ca tions. The chiller also main tains the standard digital remote ca pa bil i ties as well. Both of these remote con trol capabilities allow for the standard Energy Man age ment System (EMS) in ter face:

1. Remote Start

2. Remote Stop

3. Remote Leaving Chilled Liquid Temperature Setpoint adjustment (0-20mA or 4-20mA, 0-10VDC or 2-10VDC) or Pulse Width Modulation

4. Remote Current Limit Setpoint adjustment (0-20mA or 4-20mA, 0-10VDC or 2-10VDC) or Pulse Width Mod u la tion

5. Remote “Ready to Start” Contacts

6. Safety Shutdown Contacts

7. Cycling Shutdown Contacts

The chiller operating program resides in the Optiview control center Microboard. The control center could be equipped with either of the following Microboards:

• 031-01730-000 – shipped in new production chillers until September 2003. The program resides in a replaceable Flash Memory Card. The software version (C.MLM.02.xx.yzz) is printed on label adhered to card. Program can be upgraded by replacing the card.

• 031-02430-000 – shipped in new production chillers after September 2003. The program resides in non-removable onboard memory. The software

YORK INTERNATIONAL

Description of System and Fun da men tals of Operation

FORM 160.55-O1 (604)

version is C.OPT.02.xx.yzz, and is viewable on the DIAGNOSTICS Screen in SERVICE access level. The program can be upgraded by downloading a new program from a Program Card. Program Cards are shirt-pocket-size portable memory storage devices available from YORK.

Earlier vintage chillers could be equipped with a later Microboard due to service replacement.

Software versions (C.MLM.02.xx.yzz or C.OPT.02.xx.yzz) are alpha-numeric codes that represent the application, language package and revision levels per below. Each time the controls portion or language section is revised, the respective revision level increments.

• C – Commercial chiller

Throughout this book, reference is made to functions and features that are only available in certain Flash Memory Card revision levels (C.MLM.02.xx.xxx). To cross reference C.MLM software to C.OPT software, refer to the controls revision level. Software version C.OPT.02.04B.xxx is of the same controls revision level as C.MLM.02.04.xxx. From this starting point, both receive the same updates at each revision. Software upgrades should only be performed by a Service Technician.

The OptiView Control Center display is high light ed by a full screen graph ics display. This dis play is nested with in a stan dard keypad and is sur round ed by “soft” keys which are re de Þ ned based on the currently dis played screen. Eight buttons are avail able on the right side of the pan el and are primarily used for navigation between the sys tem screens. At the base of the display are 5 ad di tion al but tons. The area to the right of the key pad is used for data entry with a stan dard numeric key pad provided for en try of system setpoints and lim its.

The Decimal key provides accurate entry of

setpoint values.

A +/- key has also been provided to allow en try of neg a tive values and AM/PM selection dur ing time entry.

In order to accept changes made to the chiller

setpoints, the Check key is provided as a uni-

ver sal ‘En ter’ key or ‘Accept’’ symbol.

In order to reject entry of a setpoint or dismiss

an entry form, the ‘X’ key is provided as a uni-

ver sal ‘Can cel’ sym bol.

Cursor Arrow keys are pro-

vid ed to allow move ment on screens which contain a large amount of entry data. In ad di tion, these keys can be used to scroll through his to ry and event logs.

The Start/Stop control is op er at ed via a three-position rocker switch. When toggled all the way to the right, it is

considered in the STOP/RESET position. When in the

00134VIP

middle position, this is considered the RUN state. When

toggled to the left-most position, it is considered in the

START state. Each state is described in detail below:

• STOP / RESET (O)

When in this position, the chiller will not run un der

any condition. For safe ty reasons, this po si tion is re quired for many maintenance tasks to be com plet ed (such as prox im i ty probe and vane cal i bra tion). In ad di tion, the switch must be placed in this state fol low ing a Safety shut down before the chill er is al lowed to re start. This guar an tees that manual in ter ven tion has tak en place and the shut down has been ac knowl edged.

• START (◄)

The switch can only remain in this po si tion when

being acted upon by a man u al force. Once the user has re leased the switch, it au to mat i cal ly re verts to the RUN po si tion. Gen er al ly, this state only occurs mo men tari ly as the operator at tempts to locally start the unit. Once this po si tion has been sensed, if all fault con di tions are cleared, the unit will en ter the sys tem prelube (start se quence).

• RUN ( )

When in this position, the chiller is able to op er ate.

The switch spring-re turns to this state after it has

been tog gled to the START po si tion. When in this

state, the chiller is al lowed to function normally and will also al low the chill er to au to mat i cal ly re start fol low ing a Cy cling shut down. The switch must be in this state to re ceive a val id re mote start signal when op er at ing under a re mote con trol source.

OVERVIEW

The new graphical display on each control pan el al lows a wide variety of information to be pre sent ed to the user. Each screen description in this document will be gin

with a section entitled Overview which will de scribe

the graphical elements on the screen and give a short summary of the functions available. Each el e ment on the screen will then be categorized into three dis tinct groups: Display Only, Programmable and Nav i ga tion. Below is a short description of what types of in for ma tion are included in these groups.

The Programmable values and Navigation commands are also subject to access level restrictions as de scribed below. For each of these elements, an in di ca tion is giv en to show the minimum access level required to program the value or navigate to the subscreen.

DISPLAY ONLY

Values in this group are read-only parameters of in for ma tion about the chiller operation. This type of in for ma tion may be represented by a numerical value, a text string or an LED image. For numerical values, if the monitored parameter is above the normal operating range, the high limit value will be displayed along with the ‘>’ symbol; if it is below the normal operating range, the low limit value will be displayed along with the ‘<’ sym bol. In some cases, the value may be rendered in valid by other conditions and the display will use X’s to in di cate this.

PROGRAMMABLE

Values in this group are available for change by the user. In order to program any setpoints on the sys tem, the user must Þ rst be logged in with the ap pro pri ate access level. Each of the programmable values re quires a spe ciÞ c Ac- cess Level which will be indicated beside the speciÞ ed value. All of the pro gram ma ble controls in the system fall into one of the categories described below:

Access Level

In order to program any setpoints on the sys tem, the user must Þ rst login with an appropriate ac cess level. When power is applied to the chiller, the system begins with an

Access Level of VIEW. This will allow the user to navi-

gate to most screens and observe the values displayed there. However, the user will not be allowed to change any values. To change any values, the user must return to

the Home Scr een (shown by de fault when pow er is ap- plied to the system) and use the LO G IN but ton or uti lize the CHANGE SETPOINTS key de scribed be low. At

this point, the user will be prompt ed to enter a User ID and the corresponding Password. By default, the User

ID is zero (0). In order to gain stan dard OP ER A TOR level access, the Pass word would be en tered as 9 6 7 5, us ing the numeric keypad. OP ER A TOR ac cess reverts to the VIEW lev el after 10 con tin u ous min utes without

a keypress. If a custom User ID and Pass word have been deÞ ned (see User Screen ), the user may enter that User ID and the cor re spond ing Password value.

If the correct password is received, the user is au tho rized with the appropriate Access Level. If an incorrect pass word is entered, the user is notiÞ ed of the failure and prompted again. At this point the user may retry the password entry or cancel the login attempt.

Change Setpoints

On screens containing setpoints programmable at the

OPERATOR access level, a key with this label will be visible if the present access level is VIEW. This key

brings up the Access Level prompt described above. It allows the user to login at a higher Access Level with out returning to the Home Screen. After login, the user may then modify setpoints on that screen.

Setpoints

The control center uses the setpoint values to control the chiller and other devices connected to the chiller system. Setpoints can fall into several categories. They could be numeric values (such as 45.0°F for the Leav ing Chilled Liquid Temperature) or they could Enable or Disable a feature or function.

Regardless of which setpoint is being programmed, the following procedure applies:

1. Press the desired setpoint key. A dialog box ap pears dis play ing the present value, the up per and low er limits of the programmable range and the de fault value.

2. If the dialog box begins with the word “ENTER”, use the numeric keys to enter the desired value.

YORK INTERNATIONAL

OptiView Control Center

FORM 160.55-O1 (604)

Lead ing zeroes are not necessary. If a dec i mal point is nec es sary, press the ‘•’ key (i.e. 45.0).

Pressing the ▲ key, sets the entry value to the de fault

for that setpoint. Pressing the ▼ key, clears the present entry. The ◄ key is a backspace key and causes the entry point to move back one space.

If the dialog box begins with “SELECT”, use the

◄ and ► keys to select the desired value.

If the previously deÞ ned setpoint is de sired, press

the ‘X’ (Cancel) key to dismiss the di a log box.

3. Press the ‘!’ (Enter) key.

If the value is within range, it is accepted and the

dialog box disappears. The chiller will be gin to op er ate based on the new programmed value. If out of range, the val ue will not be ac cept ed and the user is prompt ed to try again.

Manual Controls

Some keys are used to perform manual control func tions. These may involve manual control of items such as the pre-rotation vanes, variable oriÞ ce (future) or hot gas bypass valve. Other keys in this category are used to ini tiate/ter mi nate processes such as cal i bra tions or re ports.

Free Cursor

On screens containing many setpoints, a speciÞ c “soft” key may not be assigned to each setpoint value. A soft key will be assigned to enable the cursor arrow keys below the numeric keypad which are used to “high light” the desired setpoint Þ eld. At this point, the ‘!’ key is pressed to bring up a dialog prompting the user to enter a new setpoint value. The ‘X’ key cancels cursor mode. (See the Schedule Screen [Fig. 24] for an example.)

NAVIGATION

In order to maximize the amount of values which the panel can display to the user and in order to place those values in context, multiple screens have been de signed to describe the chiller operation. In order to move from one screen to the next, navigation keys have been de Þ ned. These keys allow the user to either move “for ward” to a subscreen of the present screen or move “back ward” to the previous screen. Except for the Home Screen dis play, the upper-right “soft” key will always return the user to the Home Screen. Navigating with “soft” keys is as simple as pressing the key next to the label con tain ing the name of the desired screen. The system will im me di ate ly refresh the display with the graph ics for that screen. Following is a layout of all the screens and how they are connected.

Local Leaving Chilled Liquid Tem per a ture Range Access Level Re quired: OP ER A TOR

This is the range over which an analog (0-20mA or 420mA, 0-10VDC or 2-10VDC) in Analog Remote Mode or a digital signal (PWM) in Digital remote mode can reset the Leaving Chilled Liquid Temperature setpoint above

the operator programmed Base Setpoint (see be low).

Pro gram ma ble as ei ther 10°F or 20°F, with a de fault

of 20°F, it is added to the Base value to create a range

over which the re mote device can reset the setpoint. For example, if this setpoint is pro grammed for 10°F and the operator pro grammed value is 45°F, then the remote device can set the Leav ing Chilled Liq uid Tem per a ture setpoint over the range 45.0° - 55.0°F.

Local Leaving Chilled Liquid Temperature Setpoint

Access Level Re quired: OPERATOR

This value allows the user to deÞ ne the Leav ing Chilled Liquid Temperature that is to be maintained by the chill er. It is programmable over the range of 38.0°F to 70.0°F (water) or 10.0°F to 70.0°F (brine). If Smart Freeze (see below) is enabled, the range is 36.0°F to 70.0°F (water). A remote device can provide an analog signal (0-20mA or 4-20mA, 0-10VDC or 2-10VDC) in An a log Remote mode or PWM signal in Digital Remote mode that chang es the setpoint by creating an offset above the operator

pro grammed Base Leaving Chilled Liquid Tem per a ture

setpoint. This offset may be de Þ ned up to 10.0°F or

20.0°F above the Base setpoint (see the Remote Leav ing

Chilled Liquid Temperature Setpoint Range de scrip tion above). Additionally, a MicroGateway (in ISN Re mote mode) can deÞ ne the setpoint through a serial data stream. In this case, the in com ing setpoint is not an

off set that is applied to the locally programmed Base

setpoint value, but rath er is the setpoint value it self.

Leaving Chilled Liquid Temperature Cycling Offset - Shutdown

Access Level Re quired: OP ER A TOR

This value allows the user to specify the Leaving Chilled Liquid Temperature at which the chiller will shut down

on a LEAVING CHILLED LIQUID – LOW TEM- PER A TURE cycling shutdown. This is done by de Þ n ing

threshold is 36.0°F (water) or 6.0°F (brine) for the next ten (10) minutes. If Smart Freeze (see be low) is enabled, the threshold is 34.0°F for the next 10 minutes. After ten (10) minutes have elapsed, the shut down thresh old becomes the pro grammed setpoint val ue.

Leaving Chilled Liquid Temperature Cycling Offset - Restart

Access Level Re quired: OP ER A TOR

This value allows the user to specify the Leaving Chilled Liquid Temperature at which the chiller will restart

af ter a shutdown on a LEAVING CHILLED LIQ UID – LOW TEMPERATURE cycling shutdown. This is

done by deÞ ning an offset above the Leaving Chilled Liquid Temperature setpoint. It is pro gram ma ble over a range of 0°F to 70°F above the setpoint, to a max i mum restart value of 80°F. The chiller will au to mat i cal ly re start when this temperature is reached. This setpoint can be used to reduce chiller cycling by de lay ing the chiller restart until the cooling load has in creased.

DISPLAY ONLY

Leaving Chilled Liquid Temperature - Setpoint

Displays the present setpoint to which the chill er is op er at ing whether controlled remotely or locally. This val ue could come from a 0-20mA, 4-20mA, 0-10VDC or 210VDC input in An a log Remote mode, PWM sig nal in Digital Remote mode, MicroGateway interface in ISN mode or a locally pro grammed value.

Leaving Chilled Liquid T emperature Cy cling - Shut down

Displays the Leaving Chilled Liquid Tem per a ture at which the chiller will shut down to avoid over-cooling the build ing. This value is calculated by sub tract ing the Leaving Chilled Liquid Temperature Cy cling Offset – Shutdown from the Leaving Chilled Liq uid Tem per a ture Setpoint. If this value is below the absolute min i mum allowed shut down temperature the minimum val ue is displayed.

Leaving Chilled Liquid Temperature Cy cling – Re start

Displays the Leaving Chilled Liquid Tem per a ture at which

00364VIP

the chiller will restart after it has shut down due to overcooling temperature. This value is calculated by adding the Leaving Chilled Liquid Tem per a ture Cycling Offset – Re start to the Leaving Chilled Liquid Tem per a ture Setpoint.

Current limit Setpoint

Displays the active Current Limit setpoint. In Local mode, this is the locally programmed Current Limit setpoint. In ISN remote mode, this is the setpoint re ceived from the MicroGateway interface. In Analog remote mode, this is the setpoint received via 0-10VDC, 2-10VDC, 0-20mA or 4-20mA input. In Digital remote mode, this is the Pulse Width Modulation input.

PROGRAMMABLE

Local Leaving Chilled Liquid Tem per a ture Range Access Level Re quired: OPERATOR

This is the range over which an analog signal (0-20mA, 420mA, 0-10VDC or 2-10VDC) in Analog Re mote Mode or a digital sig nal (PWM) in Digital remote mode can reset the Leav ing Chilled Liquid Temperature setpoint above

the op er a tor programmed Base Setpoint (see be low).

Pro gram ma ble as either 10°F or 20°F, with a de fault

of 20°F, it is added to the BASE value to cre ate a range

over which the remote device can reset the setpoint. For ex am ple, if this setpoint is pro grammed for 10°F and the operator programmed value is 45°F, then the remote device can set the Leaving Chilled Liq uid Tem per a ture setpoint over the range 45.0° - 55.0°F.

Local Leaving Chilled Liquid Tem per a ture Setpoint

Access Level Required: OPERATOR

This value allows the user to deÞ ne the Leav ing Chilled Liquid Temperature that is to be maintained by the chill er. It is programmable over the range of 38.0°F to 70.0°F (water) or 10.0°F to 70.0°F (brine). If Smart Freeze is enabled, the range is 36.0°F to 70.0°F (water). A re mote device can provide an analog signal (0-20mA, 4-20mA, 0-10VDC or 2-10VDC) in Analog Remote mode or PWM signal in Digital Remote mode that changes the setpoint by cre at ing an off set above the operator pro grammed

BASE Leaving Chilled Liquid Tem per a ture setpoint.

This off set may be deÞ ned up to 10.0°F or 20.0°F above

the BASE setpoint (see the Remote Leav ing Chilled Liq-

uid Tem per a ture Setpoint Range de scrip tion above). Ad di tion al ly, a MicroGateway (in ISN Remote mode) can de Þ ne the setpoint through a serial data stream. In this case, the incoming setpoint is not an offset that is

ap plied to the locally programmed BASE setpoint value,

but rath er is the setpoint value itself.

Leaving Chilled Liquid Temperature Cycling Off set - Shutdown

Access Level Re quired: OPERATOR

This value allows the user to specify the Leaving Chilled Liquid Temperature at which the chiller will shut down

on a LEAVING CHILLED LIQUID – LOW TEM- PER A TURE cycling shutdown. This is done by de Þ n ing

an offset below the Leaving Chilled Liquid Tem per a ture setpoint. It is programmable over a range of 1°F to 64°F below the setpoint, to a minimum cutout of 36°F (water), 34°F (water with Smart Freeze enabled) or 6°F (brine). It es tab lish es the minimum allowed tem per a ture for the Leaving Chilled Liquid Temperature and pre vents overcooling of the building. Anytime the Leaving Chilled Liquid Temperature setpoint is in creased, the shutdown threshold is 36.0°F (water) or 6.0°F (brine) for the next ten (10) minutes. If Smart Freeze is enabled, the thresh old is 34.0°F for the next 10 minutes. After ten (10) minutes have elapsed, the shutdown threshold be comes the programmed setpoint value.

SCHEDULE SCREEN

FIG. 27

OVERVIEW

The schedule screen contains more pro gram ma ble val ues than a normal display screen. As such, each pro gram ma ble value is not linked to a speciÞ c but ton. In stead the

Select key is used to enable the cur sor ar rows which

are used to highlight the day and the start or stop time the user wishes to modify. At this point the user may

press the ‘!’ (ENTER) key to pro gram the Start / Stop

times for that day.

In order for the Start / Stop combination to be utilized, each Start time must have a cor re spond ing Stop time which occurs later in the day. The presently pro grammed schedule for a given day can be cancelled by setting both the Start time and Stop time to 12:00AM. If the Start time equals the Stop time (with any time other than 12:00AM), the chiller is OFF for that day. If the user desires the chiller to operate continuously through several days, the Stop time of Day 1 can be set to 11: 59 PM and the Start time of Day 2 can be set to 12:00 AM. The chiller will not stop but continue to operate until the stop of Day 2.

The user has the ability to deÞ ne a standard set of Start / Stop times which are utilized every week. The user may

then specify exception Start / Stop combinations for any

day of the week up to 6 weeks in advance. At the end of each week the schedule for the next week is created by com bin ing the standard week deÞ nition and the next

As many as six Operator selected parameters (Data Points) can be plotted in an X/Y graph format. The XAxis is scaled per the selected Data Collection Interval and dis played in a time of day or elapsed time format, as se lect ed with the X-axis toggle key. The Y-Axis is scaled for each parameter per the selected minimum and max i mum val ue for each parameter. Analog pa ram e ters are scaled in pressure, temperature, volts, amps, hertz or time. Dig i tal on/off parameters are scaled as zero (off) and one (on). Only one Y-Axis label is displayed at a time. The Y-Axis Toggle Key is used to toggle the Y-Axis labels through the different pa ram e ters. The Y-Axis la bel that is being displayed is iden ti Þ ed at the top of the graph. For iden ti Þ ca tion, each plot ted parameter and as so ci at ed Y-Axis labeling is color coordinated.

With Flash Memory Card version C.MLM.02.01.xxx and earlier, all trended Data Points are displayed si mul ta neous ly. With Flash Memory Card version C.MLM.02.02.xxx and later, the DATA SELECT key is used to display all trended Data Points si mul ta neous ly or select a single Data Point for display.

The parameters are sampled at the selected Data Col lec tion Interval and plotted using 450 data points across the X-Axis. If the actual value of the sampled pa ram e ter is less than the Y-Axis label minimum for that pa ram e ter, the value will be plotted at the minimum val ue. Simi-

00480VIP

larly, if the actual value is greater than the Y-Axis label maximum for that parameter, the value will be plot ted at the maximum value.

There are three types of charts that can be created:

ONE SCREEN, CONTINUOUS or TRIG GERED

(not applicable to Flash Memory Card version C.MLM.02.01.xxx and earlier). When plot ting reaches the end of the X-axis, if ONE SCREEN is selected, trending stops and data is frozen. If CONTINUOUS is selected, the oldest data is dropped from the left-hand side of the graph at the next collection interval. There af ter, the oldest data is dropped from the left hand-side of the graph at each data collection interval. If TRIG GERED is selected, data collection can be set to start or stop based upon the selected TRIGGER ACTION (START or STOP). If START is selected, data col lec tion will not begin until the Triggers have been satisÞ ed and any selected TRIGGER DELAY has elapsed. Data collection will stop at the completion of one screen of data as with the ONE SCREEN. If STOP is selected, data collection will not stop un til the Trig gers have been satisÞ ed and any selected TRIGGER DELAY has elapsed.

If a power failure occurs while the trend ing is running, the trending is stopped. Upon restoration of power, the last screen of data that was collected will be displayed on the trending screen. The START key must be pressed to initiate a new trend screen.

Collection Interval

Access Level Required: OPERATOR

Selects the interval at which the parameters are sam pled. There are 450 data points displayed across the X-Axis

of the graph. Each point represents the instantaneous value of the parameter. The user selects the time in ter val between these points. This is called the DATA COL LEC TION INTERVAL or the interval at which the pa ram e ter is sampled. This interval is programmable over the range of 1 second to 3600 seconds (1 hour), in one second increments. The selected interval not only de ter mines the sample interval, but also the full screen time display. The full screen time display is a result of the selected interval in seconds, multiplied by the 450 data

points. For example, if the Data Collection In ter val is

programmed for 900 seconds, the parameter would be sampled every 900 seconds, with the last 112.5 hours (4.7 days) of data viewable on the screen. There fore, the selected interval is a compromise between res o lu tion

and full screen time display. Select the desired Data Collection Interval as follows:

1. Determine the desired time interval (in sec onds), be tween data samples.

2. Calculate the full screen time display as follows:

450 x Data Collection Interval = full screen sec onds

full screen seconds / 60 = full screen minutes

full screen minutes / 60 = full screen hours

full screen hours / 24 = full screen days

3. Decide if the resultant sample interval and full screen display meet the requirements. If not, select a dif fer ent sample interval.

Access Level Required: OPERATOR

Only displayed if the associated slot number is not zero. This is the maximum value displayed for the Y-Axis.

Se lect ing a parameter for a Data Point sets this to the de fault value, which is the highest value allowed for that pa ram e ter. It can be changed to a value that pro vides a more appropriate resolution for the parameter

being mon i tored. To change, use the SELECT key as

described above and enter the desired value. The value must al ways be set to a value greater than the Data Point Min. Otherwise, a red graph is displayed on the Trend Screen with the words “TREND MAX MUST BE > TREND MIN”. There are 20 Y-Axis divisions. If a MINMAX span is selected that is not evenly divided by 20, the Pro gram will automatically select the next higher MAX val ue that makes the span evenly di vid ed by 20. For ex am ple, if 0.0 is selected as the MIN and 69.0 is selected as the MAX, the Program will insert 70.0 as the MAX value. If the parameter se lect ed for this data point is a digital type (on/off), this value must be set to one (1). One indicates the on state.

OVERVIEW (Flash Memory Card version C.MLM.02.02.xxx and later)

The desired data collection start/stop triggers are set up on this screen. The trend data collection can be set to start or stop based upon the status of up to two selected Triggers. The Triggers can consist of dig i tal events or analog parameters compared to thresh olds. The Trig gers can be used individually or in combination. The digital and analog parameters are selected from the Common Slots Screen (or Mas ter Slot Numbers List in this book).

The parameter selected as the Primary Trigger is com pared to a value selected as the Primary Test, using the Primary Operator as a comparator. If it is eval u at ed as true, then the data collection is started or stopped (after any selected Trigger delay) per the selected Trigger Action.

A Secondary Trigger can be evaluated with the Pri ma ry Trigger to start/stop data collection. The Pri ma ry to Secondary Operator is used to deÞ ne the Trigger combina- tions required to be true to start/stop data col lec tion. The Secondary Trigger is setup and evaluated the same as the Primary Trigger.

STATUS MESSAGES

“SYSTEM READY TO START”

The chiller is shut down but will start upon receipt of a Local or Remote start signal.

“CYCLING SHUTDOWN – AUTO RESTART”

The chiller is shut down on a CYCLING shutdown. The cause of the shutdown is still in effect and is dis played on the Details line of the Status Bar. The chiller will au to mat i cal ly restart when the CYCLING con di tion clears.

“SAFETY SHUTDOWN – MANUAL RESTART”

The chiller is shut down on a SAFETY shutdown. The cause of the shutdown is still in effect and is displayed on the Details line of the Status Bar. The chiller can be started after the Safety condition clears and the Op er a tor moves the COMPRESSOR switch to the STOP-RESET (O) position.

“SYSTEM PRELUBE”

A chiller start has been initiated and the pre-start lu bri ca tion is being performed. The Prelube duration is ei ther 30 seconds or 180 seconds, as conÞ gured with a Microboard Program Switch. The Pre-lube duration must nev er be changed by anyone other than a qualiÞ ed Ser vice Tech ni cian. The standard Prelube duration is 30 sec onds.

“SYSTEM RUN”

The chiller is running under the condition described in the Details Line of the Status Bar.

FORM 160.55-O1 (604)

“SYSTEM COASTDOWN”

The chiller has shut down and the Post-run lubrication is being performed. On electric motor drive ap pli ca tions, the Postlube duration is 150 seconds. On Steam Tur bine applications, it is 15 minutes. The actual du ra tion is de ter mined by a Microboard Program Jumper, con Þ g ured

by a qualiÞ ed Service technician.

“START INHIBIT”

The chiller is prevented from being started due to the reason displayed on the Details Line of the Status bar.

RUN MESSAGES

“MOTOR – HIGH CURRENT LIM IT”

The Compressor Motor current is > the Local or Re mote Current Limit Setpoint. The Current Limit Setpoint is pro grammed over a range of 30 to 100% of the Chill er Full Load Amps (FLA). When the motor current in creas es to the “inhibit open” threshold, the Pre-rotation Vanes are inhibited from further opening. This prevents a fur ther cur rent rise. If the current continues to rise to the “start close” threshold, the Vanes begin closing until the current falls to the “stop close” threshold. Au to mat ic Vane operation is resumed and this message au to mat i cal ly clears when the motor current decreases to the “allow open” thresh old. The thresholds are dif fer ent for the var i ous motor start er applications. To allow Þ eld calibration of the Solid State Starter (Mod “A”) Logic Board or CM-2 Current Module, pressing the Slide Valve Load key in Service access level, starts a 10 minute timer during which the current limit thresh olds are elevated. Refer to table on next page.

“MOTOR PULLDOWN LIMIT”

The Pulldown Demand Limit Setpoint timer is in ef fect and the Compressor Motor current is > the Pulldown Demand Current Limit Setpoint value. The Pre-rotation vane operation is being inhibited as de scribed in “ MO TOR – HIGH CURRENT LIMIT” message above.

START INHIBIT MESSAGES

“ANTI-RECYCLE XXMin/Sec”

The chiller is inhibited from starting because the 30 minute anti-recycle time has not yet elapsed. Time re main ing is displayed.

“VANE MOTOR SWITCH OPEN”

The chiller is inhibited from starting because the Prerotation Vanes are not fully closed.

“MOTOR CURRENT >15% FLA”

The OptiView Control Center has detected a Com pres sor Motor Current of a magnitude that is >15% of the chiller Full Load Amps for 10 continuous seconds, while the chiller is shutdown. As long as this condition ex ists, the oil pump is turned on. This is generally in dic a tive of a failure of the motor starter, Control Cen ter start cir cuits or motor current feedback circuits. After motor current is no long er detected, a SYS TEM COASTDOWN is per formed. The chiller can be start ed after motor current is no long er detected, the SYS TEM COASTDOWN has com plet ed and the COM PRES SOR switch is placed in the STOP-RE SET (O) po si tion.

“LCSSS – HIGH TEMPERATURE PHASE X – STOPPED”

(Mod. “B” Solid State Starter only) The chiller is stopped and the Liquid Cooled Solid State Starter Logic/Trigger Board has detected that the tem per a ture of phase A, B or C (designated as X in the message) Silicon Controlled RectiÞ er (SCR) module is >110°F. The starter cooling pump will run and the chill er will be inhibited from starting until the tem per a ture de creas es to <109°F.

WARNING MESSAGES

“WARNING – REAL TIME CLOCK FAILURE”

During the initialization process that occurs when pow er is applied to the OptiView Control Center, test data is written to a location in the BRAM battery backed mem o ry device (IC location U52 on Microboard). This data is then read from the BRAM and compared to the test data. If the read data is not the same as that which was

written to the device, it is assumed the BRAM and Real time Clock operation is defective and this mes sage is dis played. The BRAM should be replaced by a qualiÞ ed Service Technician. This message au to mat i cal ly clears when the BRAM problem has been solved.

“WARNING – CONDENSER OR EVAP O RA TOR XDCR ERROR”

The Evaporator pressure Transducer is indicating a high er pressure than the Condenser pressure Trans duc er after the chiller has been running for 10 minutes. This is in dic a tive of a Condenser or Evaporator Trans duc er fail ure. This message will be displayed until the condition clears and the WARNING RESET Keypad key is pressed on the home screen in OPERATOR (or high er) ac cess mode. Condition not checked in Brine mode.

“WARNING – SETPOINT OVERRIDE”

A blank BRAM battery-backed memory device (IC lo ca tion U52 on Microboard) or a failure of this device was detected during the initialization process that oc curs when power is applied to the OptiView Control Center. Due to this failure, any or all of the pro grammed Setpoints could have been corrupted. Therefore, all Setpoints have been automatically changed to their Default val ues. All Setpoints will have to be pro grammed to their de sired values. This message will clear when the WARN ING RESET key is pressed on the home screen in OP ER A TOR (or high er) access mode.

“WARNING – CONDENSER – HIGH PRES SURE LIMIT”

The Condenser Pressure exceeds the High Pressure Warning Setpoint threshold, programmed by a Service technician logged in at SERVICE access level. While this condition is in effect, the Pre-rotation Vanes are inhibited from further opening. This message au to mat i cal ly clears and the Vanes are permitted to open when the Condenser pressure decreases to 0.1 PSIA be low the Setpoint.

“W ARNING – EVAPORAT OR – LOW PRES SURE LIMIT”

The Evaporator pressure has decreased to the Warn ing threshold. This threshold is Þ xed in Water cooling ap pli - ca tions. In Brine cooling applications, the thresh old is a Þ xed amount above the programmable safety shut down threshold. The Safety threshold in Brine ap pli ca tions is determined by the Brine solution and is de ter mined by the YORK Factory. While this condition is in effect, the Pre-rotation Vanes are inhibited from fur ther open-

“LCSSS – INITIALIZATION FAILED”

When AC Power is restored to the system after a pow er failure, an initialization process occurs wherein the OptiView Con trol Center attempts to establish com mu ni ca tions through the serial communications link with the Liquid Cooled Solid State Starter. If com mu ni ca tions are not es tab lished within 10 consecutive at tempts, a Cycling shut down is performed and this message is displayed. The Control Center attempts to establish com mu ni ca tions un til suc cess ful.

“LCSSS – SERIAL COMMUNICATIONS”

After communications have been successfully es tab lished in the INITIALIZATION process, the OptiView Control Center initiates a data transmission to the Liq uid Cooled Solid State Starter on the serial com mu ni ca tions link every 2 seconds. After these com mu ni ca tions have been established, if the Control Center does not receive a reply within 10 consecutive attempts, a Cy cling shut down is performed and this message is dis played. This same Cycling shutdown is performed, along with the same message, if the Liquid Cooled Sol id State Starter does not receive a response from the con trol center after 10 consecutive attempts to com mu ni cate with the Control Center after INITIALIZATION has been suc cess ful ly completed. The Control Center at tempts to es tab lish communications until successful.

“LCSSS SHUTDOWN – REQUESTING FAULT DATA . . .”

The Liquid Cooled State Starter Logic/Trigger Board has shut down the chiller but the OptiView Control Cen ter has not yet received the cause of the fault from

the LCSSS, via the serial communications link. The LCSSS shuts down the chiller by opening the Motor Controller LCSSS Stop Contacts (K1 relay located on the start er Logic/Trig ger Board and connected between TB6-16 and TB6-53 in the OptiView Control Center). The Microboard, in the Control Center then sends a request for the cause of the fault to the Logic/Trigger Board over the serial com mu ni ca tions link. Since serial com mu ni ca tions are initiated every 2 seconds, this mes sage is typically displayed for a few seconds and then re placed with one of the below listed fault messages.

“LCSSS – STOP CONTACTS OPEN” Refer to “LCSSS SHUTDOWN – REQUESTING FAULT DATA ...” above. If the OptiView Control

Cen ter’s Microboard does not receive the cause of a starter initiated shutdown with 20 seconds of the shut down, it is as sumed it is not forthcoming and that mes sage is re placed with this message. The chiller can

be started when the Motor Controller LCSSS Stop

Con tacts close.

A missing interlock jumper between Start er Log ic/Trig ger Board J1-1 and J1-12 will also produce this mes sage.

“LCSSS – POWER FAULT”

The Liquid Cooled Solid State Starter Logic/Trigger Board has detected that the compressor motor current in one or more phases has decreased to <10% of the FLA for a minimum of 1 line cycle. This check is in hib it ed during the Þ rst 4 seconds of SYSTEM RUN and until the motor current is >25% of the FLA. The chiller will automatically restart upon completion of SYSTEM COASTDOWN.

“LCSSS – LOW PHASE X TEMPERATURE SEN SOR”

The Liquid Cooled Solid State Starter Logic/Trigger Board has detected that the temperature of the starter phase A, B or C (designated as X in the message) Sil i con Controlled RectiÞ er (SCR) Module has decreased to <37°F. This would generally be indicative of a dis con nect ed or defective sensor. If all three SCR Mod ules are indicating a temperature of <37°F, the SCR Module cooling pump turns on. This is accomplished by disconnecting all three sensors. This feature allows Ser vice Technicians to run the cooling pump while Þ ll ing the cooling system by disconnecting plugs P2, P3 and P4 in the LCSSS.

“LCSSS – RUN SIGNAL”

The Liquid Cooled Solid State Starter receives two start signals from the OptiView Control Center si mul -

ta neous ly; one via the serial communications link and one via the start re lay TB6-24 in the OptiView Control Cen ter. If they are not re ceived within 5 seconds of one another, a cycling shut down is performed and this mes sage is displayed. This is generally indicative of de fec tive wiring.

“LCSSS – INVALID CURRENT SCALE SELECTION”

There is an invalid compressor motor current scale jump er combination installed in the Liquid Cooled Sol id Starter Logic/Trigger Board J1. Jumper combination determines allowable “100% FLA” setpoint range; 7L-35 to 260A, 14L-65 to 510A, 26L-125 to 850A and 33L-215 to 1050A. The chiller will be permitted to start when the jumpers are conÞ gured correctly. Refer to YORK Starter service manual 160.00-O2 for valid jump er con Þ g u ra tions.

“LCSSS – PHASE LOCKED LOOP”

The Liquid Cooled Solid State Starter Logic/Trigger Board phase locked loop circuit was not able to main tain lock with phase A of the power line. This could be caused by a power line anomaly such as sag or jitter. A power line frequency jitter of up to 3 Hz/second can be tolerated. The chiller will automatically restart when lock has resumed.

“LCSSS – LOW SUPPLY LINE VOLTAGE”

The Liquid Cooled Solid State Starter Logic/Trigger Board has detected that the compressor motor AC pow er line voltage, in any phase, decreased below the low line voltage threshold continuously for 20 seconds. The chill er will automatically restart when the voltage in all phases returns to the restart level. The thresholds are as follows:
