a.
Digital input
Running capacity is determined by the state of digital input,
When PIN4 connects with PIN5, the pump will be mandatory to stop; if disconnected, the digital control
will be invalid;
When PIN3 connects with PIN5, the pump will be mandatory to run at 100%; if disconnected, the control
priority will be back on panel control;
When PIN2 connects with PIN5, the pump will be mandatory to run at 80%; if disconnected, the control
priority will be back on panel control;
When PIN1 connects 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 terminals 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 100%, the running capacity will be automatically reduced
to 85%;
b.
If current operating capacity is higher than 85%, the running capacity will be automatically reduced
