Run mode is the default operation mode of the system. This is the standard operation mode that is active in field application (at customer site). System can go from run mode to other operation modes through keyboard or serial ports.

11.5.1 Mode Setting

Mode defines the ODU operation mode. There are three possible operation modes:

1. STBY – standby mode

2. COOL - the unit operating at cooling cycle

3. HEAT - the unit operating at heat pump cycle

The ODU define the system operation mode according to three methods set by the display key board:

1. First request priority

The first IDU which requests different mode than STBY mode will set the new operation mode. The mode will cha mode.

The controlled input (CTT, HST, or PWR) is controlled by changing the protection level using the fuzzy logic algorithm according the input level and the change rate. There are two sets of POWER values, the selection of the values are set according to the state of the Power-Shed dry contact input. Power-Shed input open Power-Shed input sort

The total protection level is defined by the higher level of protection received.

11.5.8 Deicing

11.5.8.1 Deicing Starting Conditions

Deicing operation will start when either one of the following conditions exist: Case 1: OCT < OAT – DST AND TLD > DI Case 2: OCT < OAT – 12 AND TLD > 30 minutes. Case 3: OCT is Invalid AND TLD > DI Case 4: Unit is just switched to STBY AND OCT < OAT – DST Case 5: NLOAD = 0 AND OCT < OAT - DST Case 6: OAT is invalid AND OCT< DST AND TLD > DI AND Compressor ON Time > CTMR minutes OCT – Outdoor Coil Temperature

CONTROL SYSTEM

OAT – Outdoor Air Temperature

TLD – Time from Last Deicing

DI – Deicing Interval (Time Interval between Two Deicing)

DST – Deicing static threshold (Temperature)

Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and is 40 minutes in other cases. Deicing inter

val time is changed (increased/ decreased in 10 minutes steps) as a function of deicing time. If deicing time is shorter then former deicing time, the deicing interval time will be increased. If deicing time is longer then former deicing time, the deicing interval time will be decreased.

ers are required for unit

Confirm that the Mains voltage is between 198 and 264 VAC. If Mains voltage is out of this range, abnormal operation of the system is expected. If in range check the Power (Circuit) Breaker and look for broken or loosed cable lugs or wiring mistake(s).

12.4.2 Checking Main fuse

Check 20A fuse on the Filter Board - If burnt – check the compressor, fan or any other peripheral that can cause a short. In case of a problematic peripheral - replace it. In case no problematic peripheral, check the resistance on the DC bank (B+ & B- on the Power board), if it is less than 30

, replace the controller. Otherwise replace the burnt fuse.

In case of frequent burning fuse, replace the controller.

12.4.3 Checking PFC Chock coil

Check PFC chock connection – repair if needed. Dis-connect the chock from the controller wire extensions, check if the 2 wires of the chock are shorted. If shorted (OK) check between each wire and the metal box. If shorted replace chock, if not (OK), open the controller top cover and check if the wire extensions are connected well and if shorted. If not shorted, replace wires, if shorted (OK) than might be a controller problem – replace controller.

12.4.4 Checking the Outdoor Fan Motor

Check FAN-Power and FAN-Halls connections - Repair if needed. Rotate the fan slowly by hand. If the fan does not rotate easily, check whether something is obstructing the fan, or if the fan itself is coming into contact with the outer case, preventing it from rotating. Correct if necessary - otherwise, the fan motor bearings have seized. Replace the motor. If the fan rotates easily, use a current probe (“Clamp”) to assure AC current on each phase and it is less than 1A. In case there is no current, check the resistance between the three poles. Assure the three coil resistances are almost the same.

TROUBLESHOOTING

The normal value should be between 10 to 20. Change to Stand-by or Power OFF and re-start - If the fault is still active - replace controller.

12.4.5 Checking the Compressor

Check Compressor connections - Repair if needed. Use a current probe (“Clamp”) to assure that there is an AC current on each phase – no more than 15A. In case there is no current, check the resistance between the three poles. Assure the three coil resistances are almost the same (between 0.8 to 1.5). Change to Stand-by or Power OFF and re-start - If the fault is still “Active” - replace controller.

12.4.6 Checking the Reverse Valve (RV)

The RV has two parts, Solonoid and valve. Solonoid - Running in heating mode, check the voltage between two pins of reverse valve connector, normal voltage is 230VAC. if no power supply to RV, Check RV operation with direct 230VAC power supply, if OK, replace outdoor controller. Valve - if RV solonoid is OK (as above) but still no heating operation while compressor is On, replace the valve.

12.4.7 Checking the electrical expansion valve (EEV)

The EEV has two parts, drive and valve. When Outdoor unit is powered on, EEV shall run and have click and vibration. For assuring the problem is of the EEV parts, perform the installation test (see 11.6) a and no other indications in the diagnostics, than the problem is with the EEV (one or more). Drive - a step motor; ringed on the valve. Check the drive voltage, should be12VDC. Valve – if drive is OK (as above) but still the indoor unit perform no conditioning replace the valve (no need to take out the refrigerant, just pump down and shut off the main valves).

12.4.8 Checking the termistors

Check Thermistor connections and wiring - Repair if needed. Check Thermistor resistance – between 0ºC and 40ºC should be between 35K and 5K.

12.4.9 Checking the communication

Change to Stand-by or Power OFF and re-start - If the fault is still “Active” check Indoor to Outdoor Communication wiring and grounding connections (should be less than 2.0) - Repair if needed. If IDU failure – replace IDU controller that does not respond. If ODU failure – replace ODU.

12.4.10 Checking for electromagnetic interferance (EMC problems)

nd if fails

12.4.10.1 EMC troubles to the A/C unit

Locations most susceptible to noise :

1. Locations near broadcast stations where there are strong electromagnetic waves.

2. Locations near amateur radio (short wave) stations.

3. Locations near electronic sewing machines and arc-welding machines.

Trouble :

Either of the following trouble may occur:

1. The unit may stop suddenly during operation.

2. Indicator lamps may flicker

Correction :

The fundamental concept is to make the system less susceptible to noise

(insulate for noise or distance from the noise source):

1. Use shielded wires.

2. Move unit away from the noise source.

12.4.10.2 EMC troubles to near by home appliances

Locations most susceptible to noise :

1. A television or radio is located near the A/C and A/C wiring.

2. The antenna cable for a television or radio is located close to the A/C and A/C wiring.

3. Locations where television and radio signals are weak.

Trouble :

1. Noise appears in the television picture, or the picture is distorted.

2. Static occurs in the radio sound.

Correction

1. Select a separate power source.

2. Keep the A/C and A/C wiring at least 1 meter away from wireless devices and antenna cables.

3. Change the wireless device's antenna to a high sensitivity antenna.

4. Change the antenna cable to a BS coaxial cable.

5. Use a noise filter (for the wireless device).

6. Use a signal booster.

12.5 Precaution, Advise and Notice Items

12.5.1 High voltage in Outdoor unit controller

Whole controller, including the wires, connected to the Outdoor unit controller may have the potential hazard voltage when power is on. Touching the Outdoor unit controller may cause an electrical shock. Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else into the controller when power is on.

12.5.2 Charged Capacitors

Three large-capacity electrolytic capacitors are used in the Outdoor unit controller. Therefore, charging voltage (380VDC) remains after power down. Discharging takes about one minute after turned off. Touching the Outdoor unit controller before discharging may cause an electrical shock. When open the Outdoor unit controller cover, don’t touch the soldering pin by hand or by any conductive material.

Advise:

 Open the Outdoor unit controller cover only after one minute from power o  Measure the electrolytic capacitors voltage before farther checking controller.

Additional advises

 When disassemble the controller or  When connecting or disconnecting the connectors on the PCB, hold the whole housing,

don’t pull the wire.

 There are sharp fringes and sting on shell. Use gloves when disassemble the A/C

units.

the front panel, turn off the power supply.
