WEIGHT DISTRIBUTION AND ISOLATOR

MOUNTING POSITIONS

General Weights of specific chiller models vary significantly as options are added. As a result, total weights, weights at individual isolator positions, and actual isolator selec-tion at each position cannot be published due to the vast number of possible combinations. This informa-tion will be available when the specific chiller/ option selection is made from the local Quantech technical support. Be aware, weights will change with each op-tion along with possible isolator changes. Weights and isolators may need to be recalculated when the option selections are changed.

Whenever the isolator option is ordered, the isolators will be shipped loose with the chiller. Packed with the isolators and also in the control panel informa-tion packet is a drawing and table specifically for each chiller, based on the option selection. The drawing and table will be similar to the two samples shown below and on the following page. The drawing will show the isolator locations along with the weight in pounds and kilograms at the specific location, isolator position, and location measurements for each isolator.

Sample Isolator Location Drawings See Figure 20 below for sample printouts supplied in the isolator package and in the chiller panel literature packets.

Commissioning of this unit should only be carried out by Johnson Controls Au-thorized personnel.

Commissioning personnel should be thoroughly famil-iar with the information contained in this literature, in addition to this section.

Perform the commissioning using the detailed checks outlined. Refer to Equipment Pre-Startup And Startup Checklist on page 95 as the commissioning procedure is carried out.

PREPARATION – POWER OFF

The following basic checks should be made with the customer power to the unit switched OFF.

Inspection Inspect unit for installation damage. If found, take ac-tion and/or repair as appropriate.

Refrigerant Charge Packaged units are normally shipped as standard with a full refrigerant operating charge. Check that refrig-erant pressure is present in both systems and that no leaks are apparent. If no pressure is present, a leak test must be undertaken, the leak(s) located and repaired.

Remote systems and units are supplied with a nitrogen holding charge. These systems must be evacuated with a suitable vacuum pump/recovery unit as appropriate to below 500 microns.

Do not liquid charge with static water in the cooler.

Care must also be taken to liquid charge slowly to avoid excessive thermal stress at the charging point.

Once the vacuum is broken, charge into the condenser coils with the full operating charge as given in SEC-

TION 5 – TECHNICAL DATA.

Service and Oil Line Valves Open each compressor suction, economizer, and dis-charge service valve. If valves are of the back-seat type, open them fully (counterclockwise) then close one turn of the stem to ensure operating pressure is fed to pressure transducers. Open the liquid line service valve and oil return line ball valve fully in each system.

Compressor Oil To add oil to a circuit – connect a hand oil pump (Part No. 470-10654-000) to the 1/4” oil charging connec-tion on the compressors with a length of clean hose or copper line, but do not tighten the flare nut. Using clean oil of the correct type (“V” oil for Copeland com-pressor and “PVE” oil for Bitzer compressor), pump oil until all air has been purged from the hose then tighten the nut. Stroke the oil pump to add oil to the oil system. Approximately 1.8 to 2.3 gallons is present in the each refrigerant system. Oil levels in the oil equal-izing line sight glass should be between the bottom and the middle of the sight glass with the system OFF.

High oil levels may cause excessive oil carryover in the system. High oil concentration in the system may cause nuisance trips resulting from incorrect readings on the level sensor and temperature sensors. Tempera-ture sensor errors may result in poor liquid control and resultant liquid overfeed and subsequent damage to the compressor. While running, a visible sign of oil splash-ing in the sight glass is normal.

Fans Check that all fans are free to rotate and are not dam-aged. Ensure blades are at the same height when ro-tated. Ensure fan guards are securely fixed.

Isolation / Protection Verify all sources of electrical supply to the unit are taken from a single point of isolation. Check that the maximum recommended fuse sizes given in SECTION 5 – TECHNICAL DATA has not been exceeded.

Control Panel Check the panel to see that it is free of foreign materi-als (wire, metal chips, etc.) and clean out if required.

Power Connections Check that the customer power cables are connected correctly to the terminal blocks or optional circuit breaker. Ensure that connections of power cables with-in the panels to the circuit breaker or terminal blocks are tight.

Grounding Verify that the unit’s protective ground terminal(s) are properly connected to a suitable grounding point. En-sure that all unit internal ground connections are tight.

QUANTECH100

ISSUE DATE 12/20/2018SECTION 6 – COMMISSIONING

Supply Voltage Verify that the site voltage supply corresponds to the unit requirement and is within the limits given in SEC-

TION 5 – TECHNICAL DATA.

Water System Verify the chilled liquid system has been installed cor-rectly, and has been commissioned with the correct direction of water flow through the cooler. The inlet should be at the refrigerant piping connection end of the cooler. Purge air from the top of the cooler using the plugged air vent mounted on the extension pipe.

Flow rates and pressure drops must be within the limits given in SECTION 5 – TECHNICAL DATA. Operation outside of these limits is undesirable and could cause damage.

If mains power must be switched OFF for extended maintenance or an extended shutdown period, the com-pressor suction, discharge and economizer service stop valves should be closed (clockwise). If there is a pos-sibility of liquid freezing due to low ambient tempera-tures, the coolers should be drained or power should be applied to the chiller. This will allow the cooler heater to protect the cooler from freezing down to –20 °F. Be-fore placing the unit back in service, valves should be opened and power must be switched ON (if power is removed for more than 8 hours) for at least 8 hours (24 hours if ambient temperature is below 86 °F [30 °C]) before the unit is restarted.

Flow Switch Verify a chilled water flow switch is correctly fitted in the customer’s piping on the cooler outlet, and wired into the control panel correctly using shielded cable.

There should be a straight run of at least 5 pipe diam-eters on either side of the flow switch. The flow switch should be connected to terminals 13 and 14 of XTBC1 on the panel.

Temperature Sensor(s) Ensure the leaving liquid temperature sensor is coated with heat conductive compound (Part No. 013-00890-

000) and is inserted to the bottom of the water out-let sensor well in the cooler. This sensor is part of the pump control freeze protection operation. It provides some freeze protection and must always be fully in-serted in the water outlet sensor well.

PREPARATION – POWER ON

Perform the commissioning using the de-tailed checks outlined. Refer to Equipment Pre-Startup And Startup Checklist on page 95 as the commissioning procedure is carried out.

Apply power to the chiller. Turn on the option panel circuit breaker if supplied.

The machine is now live!

Switch Settings Assure the chiller OFF/ON UNIT switch at the bottom of the keypad is OFF. Place the optional circuit breaker handle on the panel door to ON. The customer’s dis-connection devices can now be set to ON.

Verify the control panel display is illuminated. Assure the system switches under the SYSTEM SWITCHES key are in the OFF position.

Compressor Heaters Verify the compressor heaters are energized. If the am-bient temperature is above 96 °F (36 °C) the compres-sor heaters must be on for at least 8 hours before start-up to ensure all refrigerant liquid is driven out of the compressor and the oil. If the ambient temperature is below 86 °F (30 °C), allow 24 hours.

D. CHECKING SUPERHEAT AND SUBCOOLING

The subcooling temperature of each system can be calcu-lated by recording the temperature of the liquid line at the outlet of the condenser and subtracting it from the liquid line saturation temperature at the liquid stop valve (liquid line saturation temperature is converted from a temperature/ pressure chart).

Example:

Liquid line pressure = 325 PSIG converted to temp. 101 °F minus liquid line temp. - 83 °F Subcooling = 18 °F

The subcooling should be adjusted to 18 °F (-8 °C) at de-sign conditions.

Record the liquid line pressure and its saturated temperature, liquid line temperature and subcooling below:

SYS 1 SYS 2

Liq Line Press = _______ _______PSIG

Saturated Temp = _______ _______ °F

Liq Line Temp = _______ _______ °F

Subcooling = _______ _______ °F should be checked. The superheat should be checked only after steady state operation of the chiller has been established, the leaving water temperature has been pulled down to the required leaving water temperature, and the unit is running in a fully loaded condition. Correct superheat setting for a system is 10 °F to 15 °F (5.56 °C to

8.33 °C) 18” (46 cm) from the heat exchanger.

Superheat should typically be set for no less than 10 °F with only a single compressor running on a circuit.

The superheat is calculated as the difference between the actual temperature of the returned refrigerant gas in the suction line entering the compressor and the temperature corresponding to the suction pressure as shown in a stan-dard pressure/temperature chart.

Example:

Suction Temp = 46 °F minus Suction Press 105 PSIG converted to Temp - 34 °F Superheat = 12 °F

When adjusting the expansion valve (TXV only), the ad-justing screw should be turned not more than one turn utes) between adjustments for the system and the ther-mal expansion valve to respond and stabilize.

Assure that superheat is set at a minimum of 10 °F (5.56 °C) with a single compressor running on each circuit.

12. Record the suction temperature, suction pressure, saturation temperature, and superheat of each sys-tem below:

SYS 1 SYS 2

Suction Temp = _______ _______ °F

Suction Pressure = _______ _______ PSIG

Saturation Temp = _______ _______ °F

Superheat = _______ _______ °F

E. LEAK CHECKING

sure no leaks If the unit is functioning satisfactorily during the initial operating period with no safeties trip and the compres-sors cycle to control water temperature to the setpoint, the chiller is considered ready to be placed into operation.

SECTION 7 – UNIT CONTROLS

INTRODUCTION

The Quantech Control Center is a microprocessor based control system designed to provide the entire control for the liquid chiller. The control logic embed-ded in the microprocessor based control system will provide control for the chilled liquid temperatures, as well as sequencing, system safeties, displaying status, and daily schedules. The MicroComputer Control Cen-ter consists of four basic components:

1. IPU II and I/O Boards

2. Transformer

3. Display

4. Keypad

The keypad allows programming and accessing set-points, pressures, temperatures, cutouts, daily sched-ule, options, and fault information.

Remote cycling, demand limiting and chilled liquid temperature reset can be accomplished by field sup-plied contacts.

Compressor starting/stopping and loading/unload-ing decisions are performed by the Microprocessor to maintain leaving or return chilled liquid temperature.

These decisions are a function of temperature devia-tion from setpoint.

A Master ON/OFF switch activates or deactivates the unit.

LD19046

IPU II AND I/O BOARDS

The IPU and I/O boards are assembled to function as a single microprocessor controller. The IPU II board contains a microprocessor and is the controller. The I/O board handles all of the chiller I/O (Inputs and Outputs). System inputs from pressure transducers and temperature sensors are connected to the I/O board.

The I/O board constantly scans inputs to monitor the chiller operating conditions. The input values are trans-mitted the IPU II microprocessor board. From this in-formation, the IPU II then issues commands to the I/O board relay outputs to control contactors, solenoids, etc. for Chilled Liquid Temperature Control and to re-act to safety conditions. The I/O board converts logic signals to operate relay outputs to 115VAC levels used by motor contactors, fan contactors, solenoid valves, etc. to control system operation. The low voltage side of all relay coils on the I/O board are powered by +12V.

Keypad commands are actuated upon by the micropro-cessor to change setpoints, cutouts, scheduling, operat-ing requirements, and to provide displays. The keypad and display are connected to the I/O board.

The on-board power supply converts 24VAC from 75VA, 120/24VAC 50/60Hz UL listed class 2 power transformer to +12V, +5V and +3.3V using switching and linear voltage regulators located on the I/O and IPU II boards. These voltages are used to operate integrated circuitry on the board. The 40 character display and unit sensors (transducers and temp sensors) are sup-

plied power for the micro board +5V supply. 24VAC is rectified, but not regulated, to provide unregulated +30VDC to supply all of the digital inputs.

The I/O board contains one green “Power” LED to in-dicate that the board is powered up and one red “Sta-tus” LED to indicate by blinking that the processor is operating. The I/O board also contains two sets of Receiver/Transmit LED’s, one for each available serial communication port. The receive LED’s are green, and the Transmit LED’s are red.

A jumper on the I/O board selects 4 to 20mA or 0 to 10VDC as the input type on the remote temperature reset analog input.

TRANSFORMER

A 75VA, 120/240VAC, 50/60Hz transformer is pro-vided to supply power to the Microprocessor Board, which in turn rectifies, filters, and regulates as neces-sary to supply power to the display, sensors, and trans-ducers.

DISPLAY

The 40 Character Display (2 lines of 20 characters) is a liquid crystal display used for displaying system pa-rameters and operator messages.

When a key is pressed, such as the OPER DATA key, system parameters will be displayed and will remain on the display until another key is pressed. The system

DOWN) arrow keys. The display will update all information at a rate of about 1 a second.

Display Messages may show characters indicating “greater than” (>) or “less than” (<). These characters indicate the actual values are greater than or less than the limit values which are being displayed.

KEYPAD

The 12 button non-tactile keypad allows the user to retrieve vitals system parameters such as system pres-sures, temperatures, compressor running times and starts, option information on the chiller, and system setpoints. This data is useful for monitoring chiller op-eration, diagnosing potential problems, troubleshoot-ing, and commissioning the chiller.

It is essential the user become familiar with the use of the keypad and display. This will allow the user to make full use of the capabilities and diagnostic features available.

UNIT SWITCH

A unit ON/OFF switch is just underneath the keypad.

This switch allows the operator to turn the entire unit OFF if desired. The switch must be placed in the ON position for the chiller to operate.

BATTERY BACK-UP

The IPU II contains a Real Time Clock integrated cir-cuit chip with an internal battery backup. The purpose of this battery backup is to assure any programmed values (setpoints, clock, cutouts, etc.) are not lost dur-ing a power failure regardless of the time involved in a power cut or shutdown period.

PROGRAMMING # OF COMPRESSORS

The total number of compressors is programmable un-der the PROGRAM key. Dual (2) system chillers can have 4, 5, or 6 compressors.

STATUS KEY

Unit Status Pressing the STATUS key will enable the operator to determine current chiller operating status. The messag-es displayed will include running status, cooling de-mand, fault status, external cycling device status. The display will be a single message relating to the highest priority message as determined by the microprocessor.

Status messages fall into the categories of General Sta-tus and Fault Status.

The following General, Safety, and Warning messages are displayed when the STATUS key is pressed. Fol-lowing each displayed message is an explanation per-taining to that particular message.

General Status Messages In the case of messages which apply to individual systems, SYS 1 and SYS 2 messages will both be dis-played and may be different. In the case of single sys-tem units, all SYS 2 messages will be blank.

The anti-coincidence timer is a software feature that guards against 2 systems starting simultaneously. This assures instantaneous starting current does not become excessively high due to simultaneous starts. The mi-croprocessor limits the time between compressor starts to 1 minute regardless of demand or the anti-recycle timer being timed out. The anti-coincidence timer is only present on two system units.

When this message appears, discharge pressure limit-ing is in effect. The Discharge Pressure Limiting fea-ture is integral to the standard software control; howev-er the discharge transducer is optional on some models.

Therefore, it is important to keep in mind that this con-trol will not function unless the discharge transducer is installed in the system.

The limiting pressure is a factory set limit to keep the system from faulting on the high discharge pressure cutout due to high load or pull down conditions. When the unload point is reached, the microprocessor will automatically unload the affected system by de ener-gizing one compressor. The discharge pressure unload will occur when the discharge pressure gets within 10 PSIG (0.69 barg) of the programmed discharge pres-sure cutout. This will only happen if the system is fully loaded and will shut only one compressor OFF. If the system is not fully loaded, discharge limiting will not go into effect. Reloading the affected system will oc-cur when the discharge pressure drops to 85% of the unload pressure and 10 minutes have elapsed.

When this message appears, suction pressure limiting is in effect. The suction pressure limit is a control point that limits the loading of a system when the suction pressure drops to within 15% above the suction pres-sure cutout. On a standard system programmed for 44 PSIG/3.0 Bar suction pressure cutout, the micropro-cessor would inhibit loading of the affected system with the suction pressure less than or equal to 1.15 * 44 PSIG/3.0 Bar = 50 PSIG/3.5 Bar. The system will be allowed to load after 60 seconds and after the suc-tion pressure rises above the suction pressure load limit point.
