AH500 Quick Start

3. A pump

The pump is installed near the underground pool. However, the device to which the PLC

actually connects is not the pump but the control panel. Generally speaking, three digital inputs

and one digital output are connected to the digital input/output module. (Remote control x 1 (DI)

& Run x 1 (DI) & Trip x 1 (DI) & Start x 1 (DO))

4. A level meter

The level meter is installed in the underground pool, and the signal contact is connected to the

analog input module. (0~10V correspond to 0~10M. 0 V represents that the water is 0.0 meters

deep, and 10 V represents that the water is 10.0 meters deep.)

The control condition of the pump:

1. Start: If the water level inside the water tower is low and that inside the underground pool is not

low, the pump will refill the water tower.

2. Stop: If the water level inside the water tower is high, or if the water level inside the

underground pool is low, the pump stops running.
