a. Digital input:
Running capacity is determined by the state of digital input,
When PIN4 connect with PIN5, the pump will be mandatory to stop; if disconnected, the digital
controller will be invalid;
When PIN3 connect with PIN5, the pump will be mandatory to run at 100%; if disconnected, the
control priority will be back on panel control;
When PIN2 connect with PIN5, the pump will be mandatory to run at 80%; if disconnected, the
control priority will be back on panel control;
When PIN1 connect with PIN5, the pump will be mandatory to run at 40%; if disconnected, the
control priority will be back on panel control;
The capacity of inputs (PIN1/PIN2/PIN3) could be modified according to the parameter setting.
b. RS485:
To connect with PIN6 and PIN7, the pump could be controlled via Modbus 485 communication
protocol.
Relay output (optional):
c.
Connect terminal L & N to enable external control. An additional on-off Relay is necessary
while bearing power is greater than 500W (2.5A).

8. PROTECTION AND FAILURE

8.1 High Temperature Warning and Speed Reduction
In "Auto-Inverter/Manual-Inverter Mode" and "Timer mode" (except backwash/self-
priming), when the module temperature reaches the high temperature warning trigger
threshold (81℃), it enters the high temperature warning state; when the temperature drops to
the high temperature warning release threshold (78℃), the high temperature warning state is
released. The display area alternately displays AL01 and running speed or flow
1) If AL01 displayed for the first time, the running capacity will be automatically reduced as
below:
a. If current operating capacity is higher than 85%, the running capacity will be automatically
