The New H100+ Fan & Pump Drive from LS Electric

The minimal setup and no extra equipment are required to achieve outstanding pump control and operations by using the H100+'s pump driven features.

No-flow control By controlling the output frequency and monitoring the change of the feedback value simultaneously, H100+ can detect no flow condition. No-flow conditions can be caused by closed off valves or restrictions, also known as deadhead. When no-flow is detected, H100+ puts pump into sleep mode protecting the pump and pipeline from damage that may occur by operating in such condition.

Over-cycle Protection Cycling refers to when the VFD switches from the normal operation of Auto mode to the Sleep mode. By counting and controlling the number of the cycle, H100+ can prevent pumps from cycling too frequently. Low/High Feedback Detection H100+ detects

Low/High feedback level based on the configured parameter value and generates warning, trip, or digital output by monitoring feedback values continuously.

Setpoint Timeout A blockage of the impeller, pump over-cycling, a broken pipe condition, or other restrictions could sometimes cause the feedback value deviates undesirably from the setpoint. H100+ continuously monitors the setpoint and feedback values to provide warning or trip when the difference between them is greater than configured parameter level and time.

Current Limit H100+ monitors the current level and reduces the output speed when the motor current increases to overload condition to prevent tripping, while maintaining the output frequency above the minimum speed
