   добрый день ! помогите определиться с неисправностью Р1.
   что проверено — при отключенном датчике — тип не определен , напряжение на выводах 10-11 5 в , при подсоеденении — напряжение падант до 3.5 в примерно ,как понимаю цепь работает ,
   в программировании выбирались значения разных датчиков PTC|NTC, — стабильно присутствует ошибка Р1 .
   подскажите значение сопротивления датчика
   схемы не нашел -чтобы определить прохождение сигнала до про процессора .параметры настройки приведены к исходным значениям
   проясните пожалуйста .

   при отсоедененном датчике 8.05 ком при соедененном 4.4ком — падение напряжения напряжение на датчике 3.6 в .

   датчиков 2 штуки — название их не известно.
   сам датчик 9.46один и др -9.63 ком
   вопрос — значение сопротивления датчика — пожоже мои не подходят

   подбором определил ,что мне нужен датчик примерно 700 ом .
   главный вопрос решен — контролер исправен , а датчик не тот .
   спасибо откликнувшимся.
   удачи

   Это не РТС-1000???? Я как-то по-необходимости хотел такие найти, нашел только в одном месте, но их цена (были в ассортименте) была от 700 до 1500 за штуку лет 5 назад. Проще новый прибор купить с обычными датчиками. Даже дешевле выйдет!

    На всех промконтроллерах применяются в основном 4 вида датчиков: Pt (1000 Ом при 0*С), PTC (1000 Ом при 25*С) и два типа NTC на 5 и 10 кОм при 25*С.

ERRORS

7.1

Errors

Code Meaning

Pr1

Room temperature probe error

Solutions:

—

check that the probe is the PTC or NTC type;

see P0 parameter

—

check the device-probe connection

—

check room temperature

Main consequences:

—

compressor activity will depend on C4 and C5

parameters

—

the defrost will not be activated

Pr2

Evaporator probe or condenser probe error

Solutions:

—

the same as in the previous example, but with

regard to the evaporator probe or the condenser

probe

Main consequences:

—

if P4 parameter is set at 1, the defrost interval

will last for the amount of time set with d3

parameter

—

if P4 parameter is set at 1 and d8 parameter is

set at 2 or to 3, the device will operate as if d8

parameter were set at 0

—

if P4 parameter is set at 1 or 2 and F0 param-

eter is set at 3 to 4, the device will operate as if

parameter were set at 2

—

if P4 parameter is set at 3, the condenser over-

heated alarm (code «COH») will never be acti-

vated

—

if P4 parameter is set at 3, the compressor shut

down alarm (code «CSd») will never be acti-

vated

When the cause of the error disappears, the device restores

normal operation.

ERRORS

7.1

Errors

Code Meaning

Pr1

Room temperature probe error

Solutions:

—

check that the probe is the PTC or NTC type;

see P0 parameter

—

check the device-probe connection

—

check room temperature

Main consequences:

—

compressor activity will depend on C4 and C5

parameters

—

the defrost will not be activated

Pr2

Evaporator probe or condenser probe error

Solutions:

—

the same as in the previous example, but with

regard to the evaporator probe or the condenser

probe

Main consequences:

—

if P4 parameter is set at 1, the defrost interval

will last for the amount of time set with d3

parameter

—

if P4 parameter is set at 1 and d8 parameter is

set at 2 or to 3, the device will operate as if d8

parameter were set at 0

—

if P4 parameter is set at 1 or 2 and F0 param-

eter is set at 3 to 4, the device will operate as if

parameter were set at 2

—

if P4 parameter is set at 3, the condenser over-

heated alarm (code «COH») will never be acti-

vated

—

if P4 parameter is set at 3, the compressor shut

down alarm (code «CSd») will never be acti-

vated

When the cause of the error disappears, the device restores

normal operation.
