Ответ на первый скрин — требует проведения ТО. Как правило каждые 2000м/ч. На работоспособность не влияет. Сброс возможен через сервисное меню. Пишите в ЛС — подскажу что и как.
Ответ на второй скрин. Описание чего произошло — VSD Fault 40 – IGBT Fault Phase V. Если компрессор 90 и более кВт — 90% накрылся модуль IGBT, отвчающиу за фазу V(находится по середине? Как на фото). Если до 75кВт, то там один модуль на три фазы. В разных годах устанавливались LeRoy или Semicron. Есть разница, надо уточнять. В любом случае — Нужна диагностика: Мегерить/проверка тепловых зазоров двигателя/датчиков холла.
Ответ на последний скрин: — теплуху частотника вентилятора охлаждения выбило, или неисправность ЧП вентилятора охлаждения(там данфосс установлен.)

Вращение двигателей от фазировки питания не зависить, там жестко в ЧП прописано, и без разницы как подключен компрессор, ЧП — вывезет. По Бловер фолт — смотрите теплуху, 90% проблема в ней, особенно если плавающая ошибка.
Isolation Contact Open — уточните мощность компрессора, посмотрю. Как правило на несработку конткторов указывает.

Тут скорее из баек из склепа. ЧП ингерсола не запутит двигатель при отсутствии фазы, т. там синхронный двиг. И определение направления вращения мониторится через датчики холла, в самом двигателе. При их неисправности — силовая часть не активируется. В ИР, по сути, очень быстрый шаговый двигатели на постоянных магнитах, без белечей клетки на роторе, и столь-же хитропопый ЧП, именно дя этого двигателя.

Датчиков холла -3. Если хот с одного идет сигнал не соответствия — ЭД не запускается. Точнее как он делает одну восьмую поворота ЭД, смотрит на показания ДХ, о их направлниие, и скорости. Есть проблеиа — встаёт в ошибку.
Если с 3-х IGBT выходов нет контрольных измерений, или они не соответствуют допуску за этот 1/8 проворот(в идеале) — силовая часть встаёт в защиту. Как правило, если до запуска в КТ есть не соответствие — ошибка.
Технология тестирования и выдачи ошибок… Лучше не промолчу, она мягко говоря такое себе. Но одон 100% верно, что нирвана не запустит двигатель, если есть хоть малейшее отклонение в любом узле.

И ещё, сразу не дочитал… Если Вы говорите, что двигатель некоторое время прям вращался против часовой стрелки… Проверте в меню фабричных установок — тип машины. Смысл в том, что если к примеру выбрана неправильная мощность, к примеру вместо 110кв, 90 — то ничего не произойдет, в том смысле выдаст ошибку invalid type drive или что-то подобное. А вот если вместо скажем 1s тоесть одноступенчатый в типе будет 2s, то он запросто может запуститься в обратном направлении. Смысл такого поведения в том, что на 1ступенчатой машине ротор прикручен прямо к валу ВБ. а на 2-х ступеньке — редуктор, соотв надо крутить 2 вала и направление обратное. За инструкциями по входу в фабричные установки — велкам, хотя я по-моему уже в какой-то из тем оставлял.

• Page 27: Procedure

  Power Outage: Background Power outage may have occurred during operation. Any power outage in excess of 250 ms (.25 sec) will cause the control circuit to reset. This can occur in installations with automatic reset circuit breakers. Electrical disturbances can also occur from power company interruptions such as lightning storms.

• Page 28: Grounding Problems Background

  Grounding Problems: Background A poor ground system can cause severe electrical problems. Electrical control systems can experience both over voltage and voltage sag conditions due to a poor ground. This can cause nuisance shutdowns, damage to power supply circuits, communications errors, and even be a safety hazard for fault conditions. Electrical fault conditions must have a low resistance path to earth ground.

• Page 29
  Disconnect power from machine. Set the meter for amps AC and connect the meter in series with the ground wire provided to the machine. If a recording meter is used (Fluke 87), set to 100 ms record mode. A recording meter is the preferred measurement for intermittent problems.

• Page 30: Procedure

  Set the meter for DC amps and record value in Amps DC. If measured value is greater than, or equal to, .25 Amps, a problem exists. Isolate electrical devices in compressor package and determine the source of ground current. Causes may include: faulty wiring, moisture contamination of electrical connections, motor overloads (current transformer type), control transformer, insulation breakdown of power leads, externally wired devices (remote start/stop, remote starter wiring, Sequencer, IRI, etc.)

• Page 31: Procedure

  measurements return to normal, repeat procedure and use process of elimination to find cause. External 5 VDC Short Circuit: Background The Intellisys provides two 5 VDC signals for external use. The logic supply voltage is used by the Intellisys to supply power for internal circuitry such as the EPROM, RAM, Microprocessor, etc.

• Page 32: Moisture Background

  This voltage measurement can be made with a Fluke 87 meter (or equivalent). A recording meter (Fluke 87) is preferred for intermittent problems. Set meter for Volts DC and connect and take measurements as noted: Connect from J3-25 to J3-24 Expected value = 5.0 VDC +/- .2 VDC Environmental Problems: Moisture:…

  temperature of 158° F. Although this is 43° F margin above ambient conditions, the rise above ambient must be accounted for. The typical rise above ambient inside the starter enclosure is 20° F. This is due to heat generated by the electrical equipment inside the enclosure, such as the control transformer, contactors,etc.

  lamp. If an inductive load is used, such as a relay coil, the rating should be reduced to maximum of 2.5 Amps, 250 VAC. The use of inductive loads can cause excessive arcing of these contacts. Excessive arcing can cause radiated interference (RFI) that can affect the Intellisys.

• Page 35: Procedure

  2.1 STEPPER MOTOR TEST PROCEDURE Background The stepper motor is a motor that can be moved in discrete increments of .9° for the Original Intellisys and .45° for the SG Intellisys. The motor is a constant torque device that is controlled by driver chips on the starter interface board or the power supply board.

• Page 36: Procedure

  reverses polarity to cause the stepper motor to move in the proper direction. A shorted stepper motor will almost always damage the driver chips on the Original Intellisys but will simply illuminate an overload on the SG Intellisys. See FSM for more information on the SG.

• Page 37: Procedure

  2.3 LIMIT BOARD TEST PROCEDURE Background The limit board contains two optical switches each of which emits an infrared light beam. When the light beam is interrupted, the voltage changes in a circuit that tells the controller the position of the valve. Procedure To perform this procedure, disconnect, lock and tag the incoming power.

• Page 38: Pressure Sensor Check Out Background

  2.4 PRESSURE SENSOR CHECK OUT Background The pressure sensors used on the Intellisys controllers use a 5 VDC supply and turn it into a varying voltage signal to the controller. The SE and Original use a 0-50 mv signal and the SG uses a .5-4.5 VDC signal. Both supply and signal voltages can be measured.

• Page 39: Procedure

  Procedure With a known good incandescent light connected to the output terminal, a digital voltmeter can easily read whether or not the triac is on or off. 115 VAC means on, a 0 VAC means off. This is the best way to monitor outputs on any Intellisys Controller.

• Page 40
  Connect voltmeter set to volts DC to terminals J1-10 & 9. You should read 5 VDC when 1M is de-energized and 0 VDC when 1M is energized. Star Delta Starting Only Contact 1Sa (mounted on the 1S starter contactor). Connect voltmeter set to volts DC to terminals J1-8 & 7. You should read 5 VDC when 1S is de-energized and 0 VDC when 1S is energized.

  made via connector P9. P9 is a 5-pin connector located on the left side of the controller (viewed from the front). The “Option Module” should always be installed or removed with power off. Note: the “Option Module” can be potentially damaged if installed with power on.

• Page 44: External Electrical Disturbances Background

  4.0 External Electrical Disturbances: Background These are defined as sources of interference that can adversely affect signal integrity of control systems and wiring interfaces. These types of problems can be caused by Radio Frequency Interference (RFI), Electro-Magnetic Interference (EMI), Electro-Static Discharge (ESD), lightning disturbances, and power line transients and surges.

• Page 45
  equipment, or other equipment that exhibits excessive electrical arcing during operation (i.e. DC brush motors). The level of disturbance is generally known as field strength. The electric field strength is measured in volts per meter (V/m). A hand held 5 watt transmitter can generate 10 V/m electric field strength at a distance of approximately 1 foot.
• Page 46
  Transients and surges can be caused by a variety of reasons. A few of these include: Poor or ungrounded equipment. Improperly sized power distribution systems that generate disturbances when switching large inductive or capacitive loads. Ground fault conditions. Equipment phase to ground or phase to phase conditions. Arc welding to compressor or surrounding equipment.

• Page 47: Procedure

  5.0 Membrane Switch Background The membrane switch is part of the user interface to the Intellisys control. It is a matrix of switches bonded to the Intellisys controller and electrically connected to the control circuit board. The internal membrane switch wiring to the physical switches is accomplished through conducted traces made of silver conductive ink.
