(3) Items displayed in User parameters: Pressure, Preset temperature
Preset start/stop delay
Preset type of operation
Preset linkage parameters
All above are user parameters, and the password is required to change specific internal parameters.
(4) Manufacturer parameters: they can only be viewed by the user and cannot be changed unless the password is obtained.
III. Fault alarm
1.Maintenance alarm for air filter, pre-filter and oil filter
(1) If the maintenance alarm is set to be controlled by the external differential pressure switch, the corresponding alarm is generated but
the compressor does not shut down when the switch has been activated; press "RT" to clear the fault when the maintenance has been
performed.
(2) When the alarm is set to be controlled by time, the external differential pressure switch is deactivated but the internal time is activated.
When a specified period of time has elapsed, an alarm is generated; when the maintenance has been performed, press "RT" to clear the
fault.
2.Major fault alarm: (the compressor automatically shuts down and generates an alarm immediately when a major fault is detected).
(1) In case of wrong phase sequence or loss of phase, the protection alarm will be generated, causing shutdown of compressor.
(2) In case of abnormal current of main fan or motor, the protection alarm will be generated, causing shutdown of compressor.
(3) In case of the excessive discharge temperature, an advanced alarm will be generated before the relevant alarm is generated, causing
shutdown of compressor.
(4) In case of the excessive discharge pressure, the relevant alarm will be generated, causing shutdown of compressor.
In all the above cases, the relevant alarm will be generated and the compressor will shut down. And the compressor can be restarted only
when the fault has been eliminated.
