If used in a pumped system, the device has to be fitted in the pipe after the pump. 95 It could be for controlling a circulating or centrifugal electric pump that is providing increased pressure or flow within water systems with storage tanks. The FSH10 switches the output, once the flow rate through the pipe exceeds 20 l/min. When used to activate a pump, it can give an increased flow and pressure, dependant on the pump capacity. The turn off time delay is adjustable between 0 and 10 seconds. A flow of less than 20 l/min, whether due to a lack of supply (e.g. tank empty) or to a decrease in demand(e.g. tap closing), will turn the output off again. 94 22 113 Cynergy3 Components Ltd. 7 Cobham Road Ferndown Industrial Estate Wimborne, Dorset BH21 7PE Telephone +44 (0) 1202 897969 Email:[email protected] ISO9001 C E R T I F I E D www.cynergy3.com © 2012 Cynergy3 Components, All Rights Reserved.

FSH10AR Flow switch for G1”, G2”, G3” or G4” pipes Installation information The flow switch is designed to be used in a horizontal pipe with the switch mounted through a side entry. Pipe connection is G1” (1”BSP). The device relies on the flow of liquid working in opposition to the spring loaded paddle to operate the relay. G1” socket connection The liquid flow moves paddle within the pipe, when the flow increases beyond the minimum specified level. A magnet mounted on the head of the paddle closes a magnetic switch in the control circuit, so causing this to operate the output relay. The output relay will remain energised for the time delay set, if the flow drops below the specified level and the paddle has returned to the rest position, and will then be deenrgised. Flow Direction The output relay will be energised for the time delay set, if the unit is disconnected then reconnected to the supply voltage or the test button is pushed. G1” - G4” pipe size G1” mounting thread The unit can operate on a supply voltage of either 24 or 240ac. “o” ring seal The output is a SPCO electromechanical relay with contacts rated to 10(4)A 250Vac. Adaptor ring “o” ring seal There is a spare terminal connected to the 240Vac supply that can be used, if a 240Vac supply is being used, to link to the common contact of the relay, if a 240Vac output is required.
