PCA300 System Operation
6.1. Overview
Once installation is complete, the system can be powered on. Power on the 48 VDC power supply and the pump
controller's VAC power, power sequence doesn't matter. If the 48 VDC power supply is slow to turn on relative to
the pump controller an error/warning may occur. If warning does occur then send reset signal from PLC interface
or send clear errors command from PCA300 Interface software. Note: During power-up some relays in the
controller will activate and make an audible sound.
The system can be operated from two different interfaces; the PCA300 Interface Software or the PLC Interface.
Do not operate the pump from both the PLC interface and the PCA300 Interface Software at the same time. If
running the PLC interface, PCA300 Interface Software can be used to monitor the current status of the pump.
6.2. PCA300 Interface Software
The PCA300 Interface Software (GUI) requires Windows XP or newer. The GUI is mainly for testing and
troubleshooting. It can also be used as the primary operative interface if needed. The GUI can control the pump
in either speed control mode or process mode. After installing the GUI and pump is connected to the controller via
serial port, follow the subsequent directions for each control mode.
