2.6 Alarm Diagnosis
001 F101 ・ E101
Alarm
Generating
Logic
F101 HPS activates within 30 seconds after compressor start. （OFF≧2400kPa,
ON≦1900kPa ）
E101 HPS activates during operation. （OFF≧2400kPa、ON≦1900kPa ）
Possible
Causes
＊HPS or HPS circuit including connector X6 (inverter board) failure
＊ Condenser air restriction / Short circuiting / CFM reverse rotation / Ambient temperature is
over 50 degree C
＊DMV failure (Coil failure, Valve not opening, valve clogging)
＊Discharge line of compressor is restricted ---Check valve, strainer (after HPT)
＊Mixing of non-condensable gas (water, air, etc.)
＊Refrigerant overcharging
＊Controller (CPU board) or inverter board failure
Trouble
Shooting
Stpe 1. Check value of HPS activating while watching to
HPT value on the LCD screen.
If HPS activates at lower than
HPT2400kPa, replace HPS.
Stpe 2. Check for blocking or short circuiting of air
passage on air cooled condenser, CFM reverse
rotation or stopped.
Repair as needed.
Stpe 3. DMV check
3.1 Disconnect the connector X11A (CPU board),
then check resistance of DMV coil.
3.2 Touch on coil vibration corresponding to opening
change when calibrating DMV at startup. (Refer to
Calibration valves in paragraph 1.4.6.)
3.3 Fully open valve using emergency magnet. (Refer
to paragraph 4.9.4.)
Then operate the unit without coil.
3.1 Resistance of each coil: 46±3Ω
3.2 In case that the coil does not
vibrate corresponding to opening
change, check the coil or the
controller.
3.3 If alarm is repeated, the valve
body will not operate. Replace
DMV body
Step 4. Check compressor discharge line
Check for clogging of check valve, strainer
(front of check valve)
If there is abnormality, recover
refrigerant and charge the specified
amount of refrigerant.
Stpe 5. Check for non condensable gas
Refer to paragraph 4.4
Stpe 6. Refrigerant overcharging
Controller
Action
F101 Unit stop
E101 Restart after 3 minutes
