CONTROL SYSTEM 12.1 General Functions and Operating Rules The DCI software is fully parametric. All the model dependent parameters are shown in Blue color and with Italic style [parameter]. The parameters values are given in the last section of this control logic chapter of the service manual. 12.1.1 System Operation Concept The control function is divided between indoor and outdoor unit controllers. Indoor unit is the system ‘Master’, requesting the outdoor unit for cooling/heating capacity supply. The outdoor unit is the system ‘Slave’ and it must supply the required capacity unless it enters into a protection mode avoiding it from supplying the requested capacity. The capacity request is transferred via indoor to outdoor communication, and is represented by aparameter called ‘NLOAD’. NLOAD is an integer number with values between 0 and 127, and it represents the heat or cool load felt by the indoor unit. 12.1.2 12.1.2.1 Compressor Frequency Control NLOAD setting The NLOAD setting is done by the indoor unit controller, based on a PI control scheme. The actual NLOAD to be sent to the outdoor unit controller is based on the preliminary LOADcalculation, the indoor fan speed, and the power shedding function. NLOAD limits as a function of indoor fan speed: 12.1.3 12.1.3.1 Target Frequency Setting Target Frequency Setting for GCD 030 During normal operation (excluding protections) the compressor target frequency is set according to the ODU NLOAD number received from the indoor unit. For single split channel the ODU NLOAD = IDU NLOAD ODU NLOAD Target Frequency [Hz] 0 0 < ODU NLOAD ≤ MinFreq 0 MinFreq >MinFreq MaxFreq MinFreq {min (ODU NLOAD, LoadDeadZone) MinFreq} MinFreq LoadDeadZone MinFreq Refer to the following diagram for the above description: SM GCD030 1-A.0 GB 12-1 CONTENTS CONTROL SYSTEM LoadDeadZone Seting: Model P (DCI80) Communication Channel Cooling 127 90 Single Spit Channel Multi Split Channel 12.1.4 Heating 127 127 Frequency Changes Control When the unit is running normally , the compressor frequency change rate is 1 Hz/sec. 12.1.5 12.1.5.1 Compressor Starting Control Compressor starting control for GCD 030 When started, compressor frequency must reach 30 Hz, and not go down below 30 Hz during the first 5 minutes of compressor operation, except when compressor should be stopped (see next sections for explanation). When Reaching Step1Freq Hz and Step2Freq Hz (for the first time during one continuous compressor operation) during compressor acceleration, compressor acceleration will be stopped for one minute and then continue. Note: If compressor is working constantly at a frequency between the step frequency and step frequency – 10 Hz, then it will remain in its current frequency until one minute is over. After that minute is over, there is no need to stop compressor acceleration again at the step frequency. When compressor frequency is equal or higher than Step2Freq Hz, further increasing of compressor frequency will be done in steps of HzDown1 Hz every one minute. The Normal acceleration/deceleration rate will be kept during these steps. Decelartion does not require steps. The steps limitation is ignored during Deicing protection. This logic should be followed every time frequency should be increased over Step2Freq, and not only once. Compressor frequency can not go over Step3Freq Hz during the first 10 minutes of continues compressor operation (excluding Deicing). 12.1.6 Minimum On and Off Time 3 minutes 12.1.7 Indoor Fan Control 8 Indoor fan speeds are determined for each model. 4 speeds for cool/dry/fan modes and 4 speeds for heat mode. When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate constantly at set speed. When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual speed is set according to the cool/heat load. 12.1.7.1 Turbo Speed The Turbo speed is activated during the first 30 minutes of unit operation when auto fan speed is selected and under the following conditions: Difference between set point and actual room temperature is bigger then 3 degrees. Room temperature > 22 for cooling, or < 25 for heating. 12.1.8 12.1.8.1 Outdoor Fan Control Outdoor Fan Control for DCI 80 Z OFAN operates between OFMinRPM to OFMaxRPM. The OFAN will be off when the compressor is off. when compressor is OFF, and HST>55 or faulty, OFAN will remain ON in 500 rpm for up to three minutes. IF HST falls below 55, OFAN will be switched off immediately. 12-2 CONTENTS SM GCD030 1-A.0 GB CONTROL SYSTEM The fan speed level (to be set for h-com), is defined according to the following table: OFAN Speed range OFAN speed level h-com 1 ~ 250 251 ~ 500 501~ 750 751 ~ Low Med High Max 1 2 3 4 In cooling mode: The OFAN speed is controlled according to the following objectives: Mdoe OFAN Target Implementation Cool Mode Keep the condensation temperature Keep OMT as low as possible down to 27°C. to the minimum possible value The following table describes the open loop of outdoor fan speed, at cool mode, related to the outdoor air temperature and the frequency (ROM table): Freq ~-10 0 80 160 250 300 350 0 20 40 60 80 100~ 0 0 120 210 310 400 490 Outdoor air temperature (OAT) 10 20 30 or faulty 0 0 0 220 460 600 330 730 730 550 730 730 730 730 730 7 30 730 730 40 0 730 750 750 750 750 50~ 0 730 750 750 750 750 In heating mode: The outdoor fan will always be running at OFNNoiseMaxRPM during heating operation mode. 12.1.9 EEV (Electronic Expansion Vavle) Control 12.1.9.1 EEV Control for GCD 030 The target EEV value is the sum of open loop value (OL) and a result of the accumulative correction values (CV).

If in range check the Power (Circuit) Breaker and look for broken or loosed cable lugs or wiring mistake(s). 13.1.4.2 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 30Ω, replace the controller. Otherwise replace the burnt fuse. In case of frequent burning fuse, replace the controller. 13.1.4.3 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. 13-8 CONTENTS SM GCD030 1-A.0 GB TROUBLESHOOTING 13.1.4.4 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. The normal value should be between 10Ω to 20Ω. Change to Stand-by or Power OFF and re-start - If the fault is still active - replace controller. 13.1.4.5 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 0.8Ω to 1.5Ω). Change to Stand-by or Power OFF and re-start - If the fault is still “Active” - replace controller. 13.1.4.6 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. 13.1.4.7 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 and if fails 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). 13.1.4.8 Checking the termistors Check Thermistor connections and wiring - Repair if needed. Check Thermistor resistance – between 0ºC and 40ºC should be between 35KΩ and 5KΩ. 13.1.4.9 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 2.0Ω) - Repair if needed. If IDU failure – replace IDU controller that does not respond. If ODU failure – replace ODU. SM GCD030 1-A.0 GB 13-9 CONTENTS TROUBLESHOOTING 13.1.4.10 Checking for electromagnetic interferance (EMC problems) 13.1.4.10.1 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. 13.1.4.10.2 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. 13.1.5 Precaution, Advise and Notice Items 13.1.5.1 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. 13.1.5.2 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. 13-10 CONTENTS SM GCD030 1-A.0 GB TROUBLESHOOTING 13.1.6. Advise: Open the Outdoor unit controller cover only after one minute from power off. Measure the electrolytic capacitors voltage before farther checking controller. Additional advises When disassemble the controller or the front panel, turn off the power supply. 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.
