Haier HR24D1VAR — обзор функций и сигнализации системы кондиционирования [37/41]

Превью страниц Страница 37 / 41

4.6 CN7 üüdischarging temp. sensor connector; the discharging temp. sensor connected

/disconnected failure: 30seconds later alarm; the failure can be resumable. When compressor is

running, if the discharging temp. >248, compressor will stop; if the discharging temp.<203

for 3 minutes, compressor will run.

4.7 XTüütime shorted function; twin-core pin; if it is with a jumper after being electirfied, the PCB

MCU time will be shorted;

4.8 CN8üüpressure control port, can collect the signal.

If the pressure switch acts before the units start, the system will alarm immidately.

If the pressure switch hasn't acts before the units start, the system will alarm only when the

switch acts 3 times within 30 minutes, the failure can not be resumable. Please reset the power

to clear the alarm

4.9 CTüücurrent value detected by current mutual inductor: after compressor is running, the

running current will be detected, if it is over current protection value (depended by the dip switch

setting) for continueous 20s, the unit will stop; 3 minutes later, it will resume to work. If it alarms

for 3 times within 30 minutes, the failure can not be resumable. Please reset the power to clear

the alarm
