.5 Operation
Notes:
(1) The touchscreen displays the time of each event. Except programmable logic controller (PLC)
events, the time of other events is consistent with that shown on the touchscreen.
(2) It is prohibited to disassemble the display or add a communication wire for remote control. If
you do this, the unit may be faulty due to signal interference. Our company will not take any
responsibility for any hurt or consequence arising therefrom. If you really require remote
control, you can customize the function from our company.
(3) Be cautious to choose a switch for remote control. Only a point-moving type switch can be
chosen. If you choose another type switch, the unit may automatically restart after being
powered off. Our company will not take any responsibility for any hurt or consequence arising
therefrom. When choosing a switch in remote control mode, you must choose a maintained
switch. Otherwise, the unit is likely to work in only one state.
(4) Three indicators (white, green, and red) are installed on the operating panel of the indoor
control cabinet. The white indicator is the power indicator of the unit. If the unit is powered on,
the white indicator turns on. The green indicator is the running indicator of the unit. If the unit
is operating properly, the green indicator turns on. The red indicator is the alarm indicator of
the unit. If the unit generates an alarm, the red indicator turns on.
Note: The following figure shows the home page screen of a single unit. If multiple units are in
parallel connection, the input/output screen of each unit is displayed. The operation is the same as
that performed for a single unit. The screen shown in the following figure is subject to change
without notice. The actual screen shall prevail.
After being powered on, the touchscreen automatically enters the home page.
