ECM Motor — The direct--drive motor is an X13

Electronically Commutated Motor (ECM). An ECM motor contains electronic circuitry used to convert single--phase line AC voltage into 3--phase DC voltage to power the motor circuit. The motor circuit is a DC brushless design with a permanent magnet rotor. On the

X13 ECM Motor design, the electronic circuitry is integral to the motor assembly and cannot be serviced or replaced separately.

208/230V units use a 230V motor and 460V units use a

460V motor. 575V units use a 460V motor with an autotransformer. Motor power voltage is connected to motor terminals L and N (see Fig. 6 and Fig. 7); ground is connected at terminal G. The motor power voltage is

ALWAYS present; it is not switched off by a motor contactor.

Motor operation is initiated by the presence of a 24V control signal to one of the five motor communications terminals. When the 24V signal is removed, the motor will stop. The motor control signal is switched by the defrost board’s IFO output.

Evaluating motor speed — The X13 ECM Motor uses a constant torque motor design. The motor speed is adjusted by the motor control circuitry to maintain the programmed shaft torque. Consequently there is no specific speed value assigned to each control tap setting. At the Position 5 tap, the motor speed is approximately 1050 RPM (17.5 r/s) but varies depending on fan wheel loading.

Selecting speed tap — The five communication terminals are each programmed to provide a different motor torque output. See Table 1. Factory default tap selection is

Position 1 for lowest torque/speed operation.

Selecting another speed:

1. Disconnect main power to the unit. Apply lockout/tagout procedures.

2. Remove the default motor signal lead (VIO) from terminal 1 at the motor communications terminal.

3. Reconnect the motor signal lead to the desired speed

(terminals 1 through 5).

4. Connect main power to the unit.

Motor “rocking” on start--up — When the motor first starts, the rotor (and attached wheel) will “rock” back and forth as the motor tests for rotational direction. Once the correct rotational direction is determined by the motor circuitry, the motor will ramp up to the specified speed.

The “rocking” is a normal operating characteristic of

ECM motors.

Troubleshooting the ECM motor — Troubleshooting the

X13 ECM requires a voltmeter.

1. Disconnect main power to the unit.

2. Remove the motor power plug (including the control

BRN lead) and VIO control signal lead at the motor terminals.

3. Restore main unit power.

4. Check for proper line voltage at motor power leads

BLK (at L terminal) and YEL (at N terminal).

5. Using a jumper wire from unit control terminals R to

G, engage motor operation. Check for 24v output at the defrost board terminal IFO.

6. Check for proper control signal voltages of 22V to

28V at motor signal leads VIO and BRN.

7. Disconnect unit main power. Apply lockout/tagout procedures.

8. Reconnect motor power and control signal leads at the motor terminals.

9. Restore unit main power.

10. The motor should start and run. If the motor does not start, remove the motor assembly. Replace the motor with one having the same part number. Do not substitute with an alternate design motor as the torque/ speed programming will not be the same as that on an original factory motor.

Replacing the X--13 ECM Motor — Before removing the ECM belly--band mounting ring from old motor:

1. Measure the distance from base of the motor shaft to the edge of the mounting ring.

2. Remove the motor mounting band and transfer it to the replacement motor.

3. Position the mounting band at the same distance that was measured in Step 1.

4. Hand--tighten mounting bolt only. Do not tighten securely at this time.

5. Insert the motor shaft into the fan wheel hub.

6. Securely tighten the three motor mount arms to the support cushions and torque the arm mounting screws to 60 in--lbs (6.8 Nm).

7. Center the fan wheel in the fan housing. Tighten the fan wheel hub setscrew and torque to 120 in--lbs (13.6

Nm).

8. Ensure the motor terminals are located at a position below the 3 o’clock position. See Fig. 5. Tighten the motor belly--band bolt and torque to 80 in--lbs (9.0

Nm).

Supply Fan (Belt--Drive)

The belt--drive supply fan system consists of a forward--curved centrifugal blower wheel on a solid shaft with two concentric type bearings, one on each side of the blower housing. A fixed--pitch driven pulley is attached to

the fan shaft and an adjustable--pitch driver pulley is on the motor. The pulleys are connected using a V--belt. See

Fig. 8.

--in.

Adjust belt tension by loosening the motor mounting plate front and rear bolts and sliding the plate toward the fan (to reduce tension) or away from fan (to increase tension).

Ensure the blower shaft and the motor shaft are parallel to each other (pulleys aligned). When finished, tighten all bolts and torque to 65--70 in--lb (7.4 to 7.9 Nm).

Fig. 9 -- Checking Blower Motor Belt Tension

C12093

Replacing the Belt:

NOTE: Use a belt with same section type or similar size.

Do not substitute a FHP--type belt. When installing the new belt, do not use a tool (screwdriver or pry--bar) to force the belt over the pulley flanges, this will stress the belt and cause a reduction in belt life. Damage to the pulley can also occur.

Use the following steps to replace the V--belt. See Fig. 8.

1. Loosen the front and rear motor mounting plate bolts.

2. Push the motor and its mounting plate towards the blower housing as close as possible to reduce the center distance between fan shaft and motor shaft.

3. Remove the belt by gently lifting the old belt over one of the pulleys.

4. Install the new belt by gently sliding the belt over both pulleys and then sliding the motor and plate away from the fan housing until proper tension is achieved.

5. Check the alignment of the pulleys, adjust if necessary.

6. Tighten all bolts and torque to 65--70 in--lb (7.4 to 7.9

Nm).

7. Check the tension after a few hours of runtime and re--adjust as required.

CAUTION

EQUIPMENT DAMAGE HAZARD

Failure to follow this CAUTION can result in premature wear and damage to equipment.

Do not use a screwdriver or a pry bar to place the new

V--belt in the pulley groove. This can cause stress on the V--belt and the pulley resulting in premature wear on the V--belt and damage to the pulley.

Adjustable--Pitch Pulley on Motor:

The motor pulley is an adjustable--pitch type that allows a

7

servicer to implement changes in the fan wheel speed to match as--installed ductwork systems. The pulley consists of a fixed flange side that faces the motor (secured to the motor shaft) and a movable flange side that can be rotated around the fixed flange side that increases or reduces the pitch diameter of this driver pulley. See Fig. 10.

used to tighten the locking collars. Tighten the locking collar by holding it tightly against the inner race of the bearing. Tighten the socket head cap screw. Torque cap screw to 55--60 in--lb (6.2--6.8 Nm). See Fig. 11. Check the condition of the motor pulley for signs of wear.

Glazing of the belt contact surfaces and erosion on these surfaces are signs of improper belt tension and/or belt slippage. Pulley replacement can be necessary.

As the pitch diameter is changed by adjusting the position of the movable flange, the centerline on this pulley shifts laterally (along the motor shaft). This creates a requirement for a realignment of the pulleys after any adjustment of the movable flange. Reset the belt tension after each realignment.

Inspect the condition of the motor pulley for signs of wear. Glazing of the belt contact surfaces and erosion on these surfaces are signs of improper belt tension and/or belt slippage. Replace pulley if wear is excessive.

Changing the Fan Speed:

1. Shut off unit power supply. Use proper lockout/tagout procedures.

2. Loosen belt by loosening fan motor mounting nuts.

See Fig. 8.

3. Loosen movable pulley flange setscrew. See Fig. 10.

4. Screw movable flange toward fixed flange to increase speed and away from fixed flange to decrease speed.

Increasing fan speed increases load on motor. Do not exceed the maximum specified speed.

5. Set movable flange at nearest keyway of pulley hub.

Tighten setscrew and torque to 65--70 in--lb (7.4 to 7.9

Nm).

Aligning Blower and Motor Pulleys:

1. Loosen blower pulley setscrews.

2. Slide blower pulley along blower shaft. Make angular alignment by loosening motor mounting plate front and rear bolts.

3. Tighten blower pulley setscrews and motor mounting bolts. Torque bolts to 65--70 in--lb (7.4 to 7.9 Nm).

4. Recheck belt tension.

Bearings:

The fan system uses bearings featuring concentric split locking collars. A Torx T--25 socket head cap screw is

Motor

When replacing the motor, also replace the external--tooth lock washer (star washer) under the motor mounting base; this is part of the motor grounding system. Ensure the teeth on the lock washer are in contact with the motor’s painted base. Tighten motor mounting bolts and torque to

120  12 in--lbs (14  1.4 Nm).

Change fan wheel speed by changing the fan pulley

(larger pitch diameter to reduce wheel speed, smaller pitch diameter to increase wheel speed) or select a new system (both pulleys and matching belt). The horsepower rating of the belt is primarily dictated by the pitch diameter of the smaller pulley in the drive system

(typically the motor pulley in these units). Do not install a replacement motor pulley with a smaller pitch diameter than was provided on the original factory pulley.

Before changing pulleys to increase fan wheel speed, check the fan performance at the target speed and airflow rate to determine new motor loading (bhp). Use the fan performance tables or use the Packaged Rooftop Builder software program. Confirm that the motor in this unit is capable of operating at the new operating condition. Fan shaft loading increases dramatically as wheel speed is increased.

To reduce vibration, replace the motor’s adjustable pitch pulley with a fixed pitch pulley (after the final airflow balance adjustment). This will reduce the amount of vibration generated by the motor/belt--drive system.

HEAT PUMP REFRIGERATION

SYSTEM

!

WARNING

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could cause personal injury, death and/or equipment damage.

This system uses Puron

R

(R410A) refrigerant that operates at higher pressures than standard R--22 systems and other refrigerants. No other refrigerant can be used in this system. Gauge set, hoses, and recovery system must be designed to handle Puron refrigerant. If unsure about equipment, consult the equipment manufacturer.

Outdoor Coil

The 50HCQ outdoor coil is fabricated with round tube copper hairpins and plate fins of various materials and/or coatings (see “Appendix I -- Model Number Significance” to identify the materials provided in this unit). All unit sizes use composite--type two--row coils. Composite two--row coils are two single--row coils fabricated with a single return bend end tubesheet.

Indoor Coil

The indoor coil is traditional round--tube, plate--fin technology. Tube and fin construction is of various optional materials and coatings (see Model Number

Format). Coils are multiple--row.

Recommended Outdoor Coil Maintenance and Cleaning

Routine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit. The following maintenance and cleaning procedures are recommended as part of the routine maintenance activities to extend the life of the coil.

Remove Surface Loaded Fibers:

Surface loaded fibers or dirt should be removed with a vacuum cleaner. If a vacuum cleaner is not available, a soft non--metallic bristle brush can be used. In either case, the tool should be applied in the direction of the fins. Coil surfaces can be easily damaged (fin edges can be easily bent over and damage the coating of a protected coil) when the tool is applied across the fins.

NOTE: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil. This will make cleaning efforts more difficult. Surface loaded fibers and dirt must be completely removed prior to using low velocity clean water rinse.

Periodic Clean Water Rinse:

A periodic clean water rinse is very beneficial for coils that are applied in coastal or industrial environments.

However, it is very important that the water rinse is made with very low velocity water stream to avoid damaging the fin edges. Monthly cleaning as described below is recommended.

!

CAUTION

PERSONAL INJURY AND UNIT DAMAGE

HAZARD

Failure to follow this caution can result in personal injury or equipment damage.

Only approved cleaning is recommended.

Routine Cleaning of Indoor Coil Surfaces:

Periodic cleaning with Totaline

Environmentally Sound

Coil Cleaner is essential in extending the life of coils.

This cleaner is available from Carrier Replacement

Components Division (p/n P902--0301 for one gallon

[3.8L] container, and p/n P902--0305 for a 5 gallon [19L] container). It is recommended that all coils (including standard aluminum, pre--coated, copper/copper or

E--coated coils) be cleaned with the Totaline

Environmentally Sound Coil Cleaner as described below.

Coil cleaning should be part of the unit’s regularly scheduled maintenance procedures ensuring the long life of the coil. Failure to clean the coils can result in reduced durability in the environment.

Avoid the use of:

S coil brighteners

S acid cleaning prior to painting

S high pressure washers

Refrigerant System Pressure Access Ports

There are two access ports in each circuit -- on the suction tube and the discharge tube near the compressor. These are brass fittings with black plastic caps. The hose connection fittings are standard 1/4 SAE male flare couplings.

The brass fittings are two--piece High Flow valves, with a receptacle base brazed to the tubing and an integral spring--closed check valve core screwed into the base. See

Fig. 16. This check valve is permanently assembled into this core body and cannot be serviced separately. Replace the entire core body if necessary. Service tools are available from RCD that allow the replacement of the check valve core without having to recover the entire system refrigerant charge. Apply compressor refrigerant oil to the check valve core’s bottom O--ring. Install the fitting body and torque to 9610 in--lbs (10.9  1 Nm). Do not exceed 106 in--lbs (11.9 Nm) when tightening.

PURON

R

(R--410A) REFRIGERANT

This unit is designed for use with Puron (R--410A) refrigerant. Do not use any other refrigerant in this system.

Puron (R--410A) refrigerant is provided in pink (rose) colored cylinders. These cylinders are available with and without dip tubes; cylinders with dip tubes will have a label indicating this feature. For a cylinder with a dip tube, place the cylinder in the upright position (access valve at the top) when removing liquid refrigerant for charging. For a cylinder without a dip tube, invert the cylinder (access valve on the bottom) when removing liquid refrigerant.

12

Because Puron (R--410A) refrigerant is a blend, it is strongly recommended that refrigerant always be removed from the cylinder as a liquid. Add liquid refrigerant into the system in the discharge line. If adding refrigerant into the suction line, use a commercial metering/expansion device at the gauge manifold; remove liquid from the cylinder, pass it through the metering device at the gauge set and then pass it into the suction line as a vapor. Do not remove Puron (R--410A) refrigerant from the cylinder as a vapor.

Refrigerant Charge

The amount of refrigerant charge is listed on the unit’s nameplate. Refer to Carrier Publication, “GTAC2--5

Charging, Recovery, Recycling and Reclamation Training

Manual” and the following procedures:

Unit panels must be in place when unit is operating during the charging procedure. If unit is equipped with a head pressure control device, bypass it to ensure full fan operation during charging.

Charge checking and adjustments must be made while the system is operating in Cooling only.

No Charge:

Use standard evacuation techniques for Puron (R--410A) refrigerant.. After evacuating system, weigh the specified amount of refrigerant.

THERMOSTATIC EXPANSION

VALVE (TXV)

All 50TCQ’s have a factory installed nonadjustable thermostatic expansion valve (TXV). The TXV will be a bi-flow, bleed port expansion valve with an external equalizer. TXVs are specifically designed to operate with

PuronR refrigerant, use only factory authorized TXVs.

See Fig. 15 for a typical piping schematic.

TXV Operation

The TXV is a metering device that is used in air conditioning and heat pump systems to adjust to changing load conditions by maintaining a preset superheat temperature at the outlet of the evaporator coil. The volume of refrigerant metered through the valve seat is dependent upon the following (see Fig. 17):

1. Superheat temperature is sensed by the cap tube sensing bulb on the suction tube at outlet of the evaporator coil. This temperature is converted into pressure by refrigerant in the bulb pushing downward on the diaphragm which opens the valve using the push rods. As long as this bulb and cap tube contain any liquid refrigerant, this temperature is converted into suction pressure pushing downward on the diaphragm, which tends to open the TXV valve through the push rods.

2. The suction pressure at the outlet of the evaporator coil is transferred through the external equalizer tube to the underside of the diaphragm.

3. The needle valve on the pin carrier is spring loaded, exerting pressure on the underside of the diaphragm.

Therefore, the bulb pressure equals evaporator pressure (at outlet of coil) plus spring pressure. If the load increases, the temperature increases at the bulb, which increases the pressure on the top side of the diaphragm, pushing the carrier away from the seat, opening the valve and increasing the flow of refrigerant. The increased refrigerant flow causes increased leaving evaporator pressure which is transferred through the equalizer tube to the underside of the diaphragm. This causes pin carrier spring pressure to close the TXV valve. The refrigerant flow is effectively stabilized to the load demand with a negligible change in superheat.

CAUTION

PERSONAL INJURY HAZARD

Failure to follow this caution can result in injury to personnel and damage to components.

Always wear approved safety glasses, work gloves and other recommended Personal Protective

Equipment (PPE) when working with refrigerants.

1. Recover refrigerant.

2. Remove TXV support clamp using a 5/l6-in. nut driver.

3. Remove TXV using a backup wrench on connections to prevent damage to tubing.

4. Remove equalizer tube from suction line of coil. Use file or tubing cutter to cut brazed equalizer line approximately 2 inches above suction tube.

5. Remove bulb from vapor tube inside cabinet.

6. Install the new TXV and avoid damaging the tubing or the valve when attaching the TXV to the distributor.

7. Attach equalizer tube to suction line. If coil has mechanical connection, then use wrench and back up wrench to attach. If coil has brazed connection, use file or tubing cutters to remove mechanical flare nut from equalizer line. Then use coupling to braze the equalizer line to stub (previous equalizer line) in suction line.

8. Attach TXV bulb in the same location as original (in the sensing bulb indent), wrap bulb in protective insulation and secure using the supplied bulb clamp.

See Fig. 18.

9. Route equalizer tube through suction connection opening (large hole) in fitting panel and install fitting panel in place.

10. Sweat inlet of TXV marked “IN” to liquid line. Avoid excessive heat which could damage valve.

Compressors

Lubrication:

Compressors are charged with the correct amount of oil at the factory.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution can result in damage to components.

The compressor is in a Puron (R--410A) refrigerant system and uses a polyolester (POE) oil. This oil is extremely hygroscopic, meaning it absorbs water readily. POE oils can absorb 15 times as much water as other oils designed for HCFC and CFC refrigerants.

Avoid exposure of POE oil to the atmosphere. This exposure to the atmosphere can cause contaminants that are harmful to R--410A components to form.

Keep POE oil containers closed until ready for use.

WARNING

FIRE, EXPLOSION HAZARD

Failure to follow this warning could result in death, serious personal injury and/or property damage.

Never use air or gases containing oxygen for leak testing or for operating refrigerant compressors. Pressurized mixtures of air or gases containing oxygen can lead to an explosion.

CAUTION

INSTALLATION SITE DAMAGE

Failure to follow this caution can result in damage to equipment location site.

S

Puron (R--410A) refrigerant contains polyolester

(POE) oil that can damage the roof membrane.

Caution should be taken to prevent POE oil from spilling onto the roof surface.

S

The factory also recommends that the suction and discharge lines be cut with a tubing cutter instead of using a torch to remove brazed fittings.

NOTE: Only factory--trained service technicians should remove and replace compressor units.

Compressors using Puron refrigerant contain a polyolester

(POE) oil. This oil has a high affinity for moisture. Do not remove the compressor’s tube plugs until ready to insert the unit suction and discharge tube ends.

Compressor Rotation:

CAUTION

EQUIPMENT DAMAGE

Failure to follow this caution can result in equipment damage.

Scroll compressors can only compress refrigerant if rotating in the right direction. Reverse rotation for extended times can result in internal damage to the compressor. Scroll compressors are sealed units and cannot be repaired on site location.

NOTE: When the compressor is rotating in the wrong direction, the unit makes an elevated level of noise and does not provide cooling.

On 3--phase units with scroll compressors, it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotating in the proper direction:

1. Connect service gauges to suction and discharge pressure fittings.

2. Energize the compressor.

3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start--up.

NOTE: If the suction pressure does not drop and the discharge pressure does not rise to normal levels:

4. Note that the evaporator fan is probably also rotating in the wrong direction.

5. Turn off power to the unit.

6. Reverse any two of the three unit power leads.

7. Reapply electrical power to the compressor.

8. The suction pressure should drop and the discharge pressure should rise which is normal for scroll compressors on start--up.

9. Replace compressor if suction/discharge pressures are not within specifications for the specific compressor.

Filter Drier

Replace the Filter Drier whenever refrigerant system is exposed to atmosphere. Only use factory specified liquid--line filter driers with working pressures no less than 650 psig (4482 kPa).

CAUTION

EQUIPMENT DAMAGE

Failure to follow this caution can result in equipment damage.

Do not install a suction--line filter drier in liquid line.

A liquid--line filter drier designed for use with Puron refrigerant is required on every unit.

Outdoor Fan Location

See Fig. 27.

1. Shut off unit power supply. Apply lockout/tagout procedures.

2. Remove condenser--fan assembly (grille, motor, and fan).

3. Loosen fan hub setscrews.

Non--powered type — This type requires the field installation of a general--purpose 125VAC/15AC circuit powered from a source elsewhere in the building. Observe national and local codes when selecting wire size, fuse or breaker requirements and disconnect switch size and location. Route 125VAC power supply conductors into the bottom of the utility box containing the duplex receptacle.

Unit--powered type — A unit--mounted transformer is factory--installed to step--down the main power supply voltage to the unit to 115VAC at the duplex receptacle.

This option also includes a manual switch with fuse, located in a utility box and mounted on a bracket behind the convenience outlet; access is through the unit’s control box access panel. See Fig. 28.

The primary leads to the convenience outlet transformer are not factory--connected. Selection of primary power source is a customer--option. If local codes permit, the transformer primary leads can be connected at the line--side terminals on the unit--mounted non--fused disconnect or HACR breaker switch. This will provide service power to the unit when the unit disconnect switch or HACR switch is open. Other connection methods will result in the convenience outlet circuit being de--energized when the unit disconnect or HACR switch is open. See

Fig. 30.

Duty Cycle — the unit--powered convenience outlet has a duty cycle limitation. The transformer is intended to provide power on an intermittent basis for service tools, lamps, etc; it is not intended to provide 15 amps loading for continuous duty loads (such as electric heaters for overnight use). Observe a 50% limit on circuit loading above 8 amps (i.e., limit loads exceeding 8 amps to 30 minutes of operation every hour).

PROTECTIVE CONTROLS

Compressor Protection

Over--current

The compressor has internal line--break motor protection.

Over--temperature:

The compressor has an internal protector to protect it against excessively high discharge gas temperatures.

23

High Pressure Switch:

The system is provided with a high pressure switch mounted on the discharge line. The switch is stem--mounted and brazed into the discharge tube. Trip setting is 630 psig  10 psig (4344  69 kPa) when hot.

Reset is automatic at 505 psig (3482 kPa).

Loss of Charge Switch:

The system is protected against a loss of charge and low evaporator coil loading condition by a loss of charge switch located on the liquid line and a freeze protection thermostat on the indoor coil. The switch is stem--mounted. Loss of Charge Switch trip setting is

27 psig  3 psig (186  21 kPa). Reset is automatic at 44 

3 psig (303  21 kPa).

Freeze Protection Thermostat trip setting is 30_F  5_F

(--1_C  3_C). Reset is automatic at 45_F  5_F (7_C

3_C).

Supply (Indoor) Fan Motor Protection:

Disconnect all electrical power and apply appropriate

Lock--out/Tagout procedures when servicing the fan motor.

Motors are equipped with an over--temperature device

(Thermik), internal line break, external circuit breaker or electronic controlled circuits for overload protection. All protection schemes are automatically reset except for units having the 2--speed indoor fan option (VFD) or external circuit breakers. These two protection schemes are classified as manual reset. The type of device depends on several factors including motor size, voltage and other options in the unit (i.e. VFD).

The Thermik device is a snap--action over--temperature protection device that is imbedded in the motor windings.

It is also a pilot--circuit device that is wired into the unit’s

24V control circuit. When this device reaches its trip set point, it opens the 24V control circuit and causes all unit operation to stop. This device resets automatically when the motor windings cool. Do not bypass this device to correct trouble. Determine the cause of the problem and correct it.

The External motor overload device is a specially--calibrated circuit breaker that is UL recognized as a motor overload controller. It is an over--current device. When the motor current exceeds the circuit breaker set point, the device opens all motor power leads and the motor shuts down. Reset requires a manual reset at the overload switch. This device (designated IFCB) is located on the side of the supply fan housing, behind the fan access panel.

Troubleshooting supply fan motor overload trips —

The supply fan used in the 50HCQ units is a forward--curved centrifugal wheel. At a constant wheel speed, this wheel has a characteristic that causes the fan shaft load to DECREASE when the static pressure in the unit--duct system increases and to INCREASE when the static pressure in the unit--duct system decreases (and fan airflow rate increases). Motor overload conditions typically develop when the unit is operated with an access panel removed, with unfinished duct work, in an economizer--open mode, or a leak develops in the duct system that allows a bypass back to unit return opening.

Outdoor Fan Motor Protection:

The outdoor fan motor is internally protected against over--temperature.

Control Circuit, 24V

The control circuit is protected against over--current conditions by a circuit breaker mounted on control transformer TRAN. The Control Circuit is reset manually.

COMMERCIAL DEFROST CONTROL

The Commercial Defrost Control Board (DFB) coordinates thermostat demands for supply fan control, 1 or 2 stage cooling, 2 stage heating, emergency heating and defrost control with unit operating sequences. The DFB also provides an indoor fan off delay feature (user selectable). See Fig. 32 for board arrangement.

Reversing valve control — The DFB has two outputs for unit reversing valve control. Operation of the reversing valves is based on internal logic; this application does not use an “O” or “B” signal to determine reversing valve position. Reversing valves are energized during the cooling stages and the defrost cycle and de--energized during heating cycles. Once energized at the start of a cooling stage, the reversing valve will remain energized until the next heating cycle demand is received. Once de--energized at the start of a Heating cycle, the reversing valves will remain de--energized until the next cooling stage is initiated.

Compressor control — The DFB receives inputs indicating Stage 1 Cooling, Stage 2 Cooling (sizes 08 --

12) and Stage 1 Heating from the space thermostat or unit control system (PremierLink or RTU--OPEN); it generates commands to start compressors with or without reversing valve operation to produce Stage 1 Cooling (one compressor), Stage 2 Cooling (both compressors run) or

25

Stage 1 Heating (both compressors run on 8--12 systems.

The 04--07 systems have only one compressor).

Auxiliary (Electric) Heat control — The 50HCQ unit can be equipped with one or two auxiliary electric heaters, to provide a second stage of heating. The DFB will energize this Heating System for a Stage 2 Heating

Command (heaters operate concurrently with compressor(s) in the Stage 1 Heating cycle), for an

Emergency Heating sequence (compressors are off and only the electric heaters are energized) and also during the

Defrost cycle (to eliminate a “cold blow” condition in the space).

Defrost — The defrost control mode is a time/temperature sequence. There are two time components: The continuous run period and the test/defrost cycle period.

The temperature component is provided by Defrost

Thermostat 1 and 2 (DFT1 and DFT2 (A08--D09 only) mounted on the outdoor coil.

The continuous run period is a fixed time period between the end of the last defrost cycle (or start of the current

Heating cycle) during which no defrost will be permitted.

This period can be set at 30, 60, 90 or 120 minutes by changing the positions of DIP switches SW1 and SW2

(see Fig. 34 and Table 9). The default run periods are 60 minutes for unit sizes 04--06, 30 minutes for unit size 07,

90 minutes for unit sizes 08--09 and 60 minutes for unit size 12.

C09283

Fig. 34 -- DIP Switch Settings — Defrost Board

At the end of the continuous run period, the defrost control will test for a need to defrost. On unit sizes 04--07

(single compressor designs), DFT1 controls the start and termination of the defrost cycle. If DFT1 is still open, the defrost test/run window is closed and the control repeats the continuous run period. If DFT1 is closed, the defrost cycle is initiated. The defrost period will end when DFT1 opens (indicating the outdoor coil has been cleared of frost and ice) or a 10 minute elapsed period expires, whichever comes first.

On unit sizes 08 and 12 (two circuit designs), DFT2

(located on the bottom circuit of the outdoor coil on the

08--09 size and the outdoor coil with two bends on the 12 size) controls the start and termination of the defrost cycle. If DFT2 is still open, the defrost test/run window is closed and the control repeats the continuous run period.

If DFT2 is closed, the defrost cycle is initiated in Circuit

2. The defrost period will end when DFT2 opens

(indicating the outdoor coil has been cleared of frost and ice) or a 10 minute elapsed period expires, whichever comes first.

On sizes 08--12, Circuit 1’s defrost thermostat DFT1

(located on the upper circuit of the outdoor coil on 08--09 size and the outdoor coil with one bend on the --12 size.) cannot initiate a unit defrost cycle; only DFT2 can do this.

But once Circuit 2 is in defrost, the DFB will monitor the status of DFT1. If DFT1 closes during a Circuit 2 defrost cycle, Circuit 1 will also enter a defrost cycle. Circuit 1’s defrost cycle will end when DFT1 opens (indicating the upper portion of the outdoor coil is cleared of frost and ice) or the Circuit 2 defrost cycle is terminated.

At the end of the unit defrost cycle, the unit will be returned to Heating cycle for a full continuous run period.

If the space heating load is satisfied and compressor operation is terminated, the defrost control will remember where the run period was interrupted. On restart in

Heating, the defrost control will resume unit operation at the point in the run period where it was last operating.

Defrost Thermostats — These are temperature switches that monitor the surface temperature of the outdoor coil circuits. These switches are mounted on the liquid tube exiting the outdoor coil heating circuits. These switches close on temperature drop at 30_F (--1_C) and reset open on temperature rise at 80_F (27_C).

Indoor Fan Off Delay — The DFB can provide a 60 sec delay on Indoor Fan Off if the thermostat’s fan selector switch is set on AUTO control. DIP Switch SW3 on the

DFB selects use of the fan off time delay feature. Setting

SW3 in the OPEN position turns the Fan Off Delay feature on; setting SW3 in the CLOSED position disables this feature. The delay period begins when Y1 demand or

W1 demand by the space thermostat is removed.

Defrost Speedup Functions — The DFB permits the servicer to speed--up the defrost cycle. There are two speed--up sequences: relative speed--up and an immediate forced defrost. Speed--up sequences are initiated by shorting jumper wires JMP17 and JMP18 together (see

Fig. 32); use a flat--blade screwdriver.

Shorting the jumpers for a period of 1 to 3 seconds reduces the defrost timer periods by a factor of 0.1

sec/minute. (For example, the 90 minute run period is reduced to 9 seconds) The DFB will step the unit through a Heating cycle and a Defrost cycle using these reduced time periods. This mode ends after the Defrost cycle.

Shorting the jumpers for a period of 5 to 20 secs bypasses the remaining continuous run period and places the unit in a Forced Defrost mode. If the controlling DFT is closed when this mode is initiated, the unit will complete a normal defrost period that will terminate when the controlling DFT opens or the 10 minute defrost cycle limit is reached. If the controlling DFT is open when this mode is initiated, the Defrost cycle will run for 30 secs. Both modes end at the end of the Defrost cycle.

ELECTRIC HEATERS

50HCQ units can be equipped with field--installed accessory electric heaters. The heaters are modular in design, with heater frames holding open coil resistance wires strung through ceramic insulators, line--break limit switches and a control contactor. One or two heater modules can be used in a unit.

Single Point Boxes and Supplementary Fuses — When the unit MOCP device value exceeds 60A, unit--mounted supplementary fuses are required for each heater circuit.

These fuses are included in accessory Single Point Boxes, with power distribution and fuse blocks. The single point box will be installed directly under the unit control box, just to the left of the partition separating the indoor section (with electric heaters) from the outdoor section.

The Single Point Box has a hinged access cover. See

Fig. 38.

Single

Point Box pilot--circuit/manual reset limit switch to protect the unit against over--temperature situations.

Line--break/auto--reset limit switches are mounted on the base plate of each heater module. See Fig. 39. These are accessed through the indoor access panel. Remove the switch by removing two screws into the base plate and extracting the existing switch.

Pilot--circuit/manual reset limit switch is located in the side plate of the indoor (supply) fan housing. See Fig. 36 and Fig 39.

Completing Heater Installation

Field Power Connections — Tap conductors must be installed between the base unit’s field power connection lugs and the Single Point Box (with or without fuses). See

Fig. 38. Refer to unit wiring schematic. Use copper wire only. For connection using the single point box without fuses, connect the field power supply conductors to the heater power leads and the field--supplied tap conductors inside the Single Point Box. Use UL approved pressure connectors (field--supplied) for these splice joints.

On 50HCQ units, all fuses are 60A. Single point boxes containing fuses for 208/230V applications use UL Class

RK5 250V fuses (Bussmann FRNR 60 or Shawmut TR

60R). Single point boxes for 460V and 575V applications use UL Class T 600V fuses (Bussmann JJS 60 or

Shawmut A6T 60). (Note that all heaters are qualified for use with a 60A fuse, regardless of actual heater ampacity, so only 60A fuses are necessary.)

On 07 -- 09 size units, unit heater applications not requiring supplemental fuses require a special Single

Point Box without any fuses. Connect power supply conductors to heater conductors and field--supplied base unit power tap leads (see text below re: “Completing

SMOKE DETECTORS

Smoke detectors are available as factory--installed options

(FIOP) on 50HCQ models. Smoke detectors can be specified for Supply Air only or for Return Air with or without economizer or in combination of Supply Air and

Return Air. Return Air smoke detectors are arranged for vertical return configurations only. All components necessary for operation are factory--provided and mounted. The unit is factory--configured for immediate smoke detector shutdown operation; additional wiring or modifications to unit terminal board can be necessary to complete the unit and smoke detector configuration to meet project requirements.

System

The smoke detector system consists of a four--wire controller and one or two sensors. Its primary function is to shut down the rooftop unit in order to prevent smoke from circulating throughout the building. It is not to be used as a life saving device.

Controller

The controller (see Fig. 44) includes a controller housing, a printed circuit board, and a clear plastic cover. The controller can be connected to one or two compatible duct smoke sensors. The clear plastic cover is secured to the housing with a single captive screw for easy access to the wiring terminals. The controller has three LEDs (for

Power, Trouble and Alarm) and a manual test/reset button

(on the cover face).

printed circuit board, a clear plastic cover, a sampling tube inlet and an exhaust tube. The sampling tube (when used) and exhaust tube are attached during installation.

The sampling tube varies in length depending on the size of the rooftop unit. The clear plastic cover permits visual inspections without having to disassemble the sensor. The cover attaches to the sensor housing using four captive screws and forms an airtight chamber around the sensing electronics. Each sensor includes a harness with an RJ45 terminal for connecting to the controller. Each sensor has four LEDs (for Power, Trouble, Alarm and Dirty) and a manual test/reset button (on the left--side of the housing).

Air is introduced to the duct smoke detector sensor’s sensing chamber through a sampling tube that extends into the HVAC duct and is directed back into the ventilation system through a (shorter) exhaust tube. The difference in air pressure between the two tubes pulls the sampled air through the sensing chamber. When a sufficient amount of smoke is detected in the sensing chamber, the sensor signals an alarm state and the controller automatically takes the appropriate action to shut down fans and blowers, change over air handling systems, notify the fire alarm control panel, etc.

The sensor uses a process called Differential Sensing to prevent gradual environmental changes from triggering false alarms. A rapid change in environmental conditions, such as smoke from a fire, causes the sensor to signal an alarm state but dust and debris accumulated over time does not.

30

For installations using two sensors, the duct smoke detector does not differentiate which sensor signals an alarm or trouble condition.

Smoke Detector Locations

Supply Air — The Supply Air smoke detector sensor is located to the left of the unit’s indoor (supply) fan. See

Fig. 46. Access is through the fan access panel. There is no sampling tube used at this location. The sampling tube inlet extends through the side plate of the fan housing

(into a high pressure area). The controller is located on a bracket to the right of the return filter, accessed through the lift--off filter panel.

face downward, into the return air stream. The sampling tube is connected via tubing to the return air sensor that is mounted on a bracket high on the partition between return filter and controller location. (This sensor is shipped in a flat--mounting location. Installation requires that this sensor be relocated to its operating location and the tubing to the sampling tube be connected. See “Completing

Installation of Return Air Smoke Sensor” for installation steps.)

(Operating Position Shown)

Highlight C: 24V power signal via ORN lead is removed at Smoke Detector input on CTB (Control Terminal

Board); all unit operations cease immediately.

PremierLink Control: Unit operating functions (fan, cooling and heating) are terminated as described above. In addition:

Highlight D: On smoke alarm condition, the smoke detector NO Alarm contact will close, supplying 24V power to GRA conductor.

Highlight E: GRA lead at Smoke Alarm input on CTB provides 24V signal to FIOP DDC control.

PremierLink: This signal is conveyed to PremierLink

FIOPs TB1 at terminal TB1--6 (BLU lead). This signal initiates the FSD sequence by the PremierLink control.

FSD status is reported to connected CCN network.

RTU--OPEN: The 24V signal is conveyed to

RTU--OPEN’s J1--10 input terminal. This signal initiates the FSD sequence by the RTU--OPEN control. FSD status is reported to connected BAS network.

Using Remote Logic: Five conductors are provided for field use (see Highlight F in Fig. 51) for additional annunciation functions.

CAUTION

EQUIPMENT DAMAGE

Failure to follow this caution can result in equipment damage.

Scroll compressors can only compress refrigerant if rotating in the right direction. Reverse rotation for extended times can result in internal damage to the compressor. Scroll compressors are sealed units and cannot be repaired on site location.

On 3--phase units with scroll compressors, it is important to be certain compressor is rotating in the proper direction. To determine whether or not compressor is rotating in the proper direction:

1. Connect service gauges to suction and discharge pressure fittings.

2. Energize the compressor.

3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start--up.

If the suction pressure does not drop and the discharge pressure does not rise to normal levels:

1. Note that the evaporator fan is probably also rotating in the wrong direction.

2. Turn off power to the unit and apply lockout/tagout procedures.

3. Reverse any two of the unit power leads.

4. Re--energize to the compressor. Check pressures.

The suction and discharge pressure levels should now move to their normal start--up levels.

NOTE: When the compressor is rotating in the wrong direction, the unit will make an elevated level of noise and will not provide cooling.

Refrigerant Service Ports

APPENDIX III. FAN PERFORMANCE

General Fan Performance Notes:

1. Interpolation is permissible. Do not extrapolate.

2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure caused by any FIOPs or accessories.

3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories can add static pressure losses.

4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work, Carrier recommended the lower horsepower option.

5. For information on the electrical properties of Carrier’s motors, please see the Electrical information section of this book.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percentage of voltage imbalance.

% Voltage Imbalance = 100 x max voltage deviation from average voltage average voltage

Example: Supply voltage is 230-3-60

AB = 224V

BC = 231V

AC = 226V

Average Voltage =

=

(224 + 231 + 226)

227

=

681

3

Determine maximum deviation from average voltage.

(AB) 227 – 224 = 3V

(BC) 231 – 227 = 4V

% Voltage Imbalance

Maximum deviation is 4V.

Determine percent of voltage imbalance.

= 100 x

4

227

= 1.76%

This amount of phase imbalance is satisfactory as it is below the maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%, contact your local electric utility company immediately.
