Ktech Model PC1104-HL Pump Controller
CP1100 Overfill Protection Device


Pump,ControllersThe Ktech Model PC1104-HL Pump Controller operates one pump 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 FS-A provides a HIGH level warning and emergency shutdown for all pump operations. A red pilot light provides the visual alarm indication. There is a buzzer with mute switch. The alarm circuit resets automatically.

  • The 2nd contact FS-B stops the pump.

  • The 3rd contact FS-C starts the pump. A green pilot light provides indication that the pump is running.

  • The bottom contact FS-D triggers a LOW alarm signal. A red pilot light provides the visual alarm indication. There is a buzzer with mute switch. The alarm circuit resets automatically.

Under normal operation, the liquid level doesn’t fall to the LOW level. When the liquid level falls to the 3rd contact, the pump will start and the tank will fill. The pump will stop when the level reaches the 2nd contact. The green pilot light indicates the pump is running.

If either the HIGH or LOW level alarm sounds, it indicates that either the pump has failed or a float switch contact has failed.

  • Across-the-line contactor

  • Control transformer

  • Pump alternator
