The Model PC1103-HL-2R Duplex Pump Controller has a provision for 4 float switch inputs. High, Low Alarm and Start & Stop pumps. The Model PC1103-HL-2R Duplex Pump Controller automatically alternates the operation of two pumps to control the level of a liquid in a tank. It is used in conjunction with a Ktech model FS301-4 float switch.
The top contact FS1-A indicates high alarm The second contact FS1-B stops one or both pumps. The third contact FS1-C starts the lead pump.The bottom contact FS1-D starts the lag pump and signals a low alarm. Under normal operation, the liquid level doesnt fall to the lag pump contact level. When the liquid level falls to the FS1-C level, one pump will start and the tank will fill. The pump will stop when the level reaches the FS1-B level. On the next cycle, the second pump will start. The pumps alternate each cycle. The pilot lights indicate which pump is running.
1. If the level continues to fall with the lead pump running, the bottom contact will close and the lag pump will start. Both pumps will run until the level reaches the FS1-B contact and both pumps will stop. After the liquid level rises above low alarm level, the reset pushbutton will return the system to alternate pump control and turn off low level alarm light.
2. If the lead pump fails to start, the lag pump will start when the level drops to the bottom contact. The pump will run until the level reaches the the FS1-B contact.
