Field Settings for Outdoor Unit
Part 5 Field Settings and Test Operation
121
Mode 2-26:
Start time automatic night-time low noise
operation. When the auto
night-time low noise operation is active (refer to field setting 2-22) outdoor will start when
start time is reached time is reached. The time judgment is taken from outdoor air tendency.
Default value: 2 (10:00 PM)
Field setting 1: 8:00 PM, 3: 12:00 AM (midnight).
Mode 2-27:
Stop time automatic night-time low noise
operation. When the auto
night-time low noise operation is active (refer to field setting 2-22), outdoor unit will stop the
night-time low noise operation level automatically when stop time is reached.
Default value: 3 (8:00 AM)
Field setting 1: 6:00 AM, 2: 7:00 AM
Mode 2-28:
Power transistor check
mode. To evaluate the output of the power transistors.
Use this function in case error code is displayed related to defective inverter PCB or
compressor is locked.
Default value: 0. Power transistor check mode is not active.
Field setting 1: Power transistor check mode is active.
Function:
Inverter PCB gives output of 10 Hz in sequence by all 6 transistors. Remove the
U/V/W terminals of the compressor, and connect to the inverter checker module. If all
6 LEDs blink, the transistors switch correctly.
When the power transistor check mode is interrupted, after internal power circuit is
disconnected on the inverter PCB, 2 LEDs will light up to indicate discharge of the DC
voltage.
Wait until the LEDs are OFF before returning fasten terminals back to the compressor
terminals.
Minimum requirements to refer to the result on the inverter checker module:
All 3 phases and neutral are available, and
Inverter PCB control is active. Check if the green LED “HAP” on the inverter PCBs are
blinking normal (approx. 1/ second). If LEDs are OFF, need to exit the “standby
mode” of the inverter:
Disconnect and reconnect power supply control PCB, or
Forced thermostat ON condition, or
Make shortly set 2-6-1 (forced thermostat ON indoor), or
2-20-1 (manual refrigerant charge).
Once the LED is blinking on the inverter PCB, change related setting immediately
back to set 0 to deactivate related function.
Diode module generates the required 500 VDC.
