Page 19: Chapter 4 Placing System Into Operation
CHAPTER 4 - PLACING SYSTEM INTO OPERATION It is suggested the following sequence be used when the PCS140e.1 is started for the first time. If, at any time, the expected result is not obtained, see the troubleshooting chapter. Before applying power to the unit inspect all wiring 4.1-Supplying Power to the System... - Page 20 PCS140e.1 3.Enter the Low Pressure time delay. This is the amount of time (in seconds) that the system will wait before starting additional pumps on a low pressure condition. 4.Repeat for the High Pressure setpoint. When the header pressure rises above this level for the amount of time defined with the delay setpoint, a pump will be turned off.
