Page 2: Redefining Motor Control
Redefining Motor Control The original pioneers of soft start technology, Fairford Electronics Limited have been at the forefront of motor control innovation since the 1970’s. Fairford have manufactured and supplied over 1 million products into the market place and are recognised as the reference point for many control solution providers worldwide. - Page 3 Short Circuit Fairford soft starts are not short circuit proof. After severe overload or short circuit, the operation of the soft start should be fully tested by an authorised service agent.

- Page 5 Environment - installation Enclosure Ventilation When fitting synergy™ into a cabinet, ventilation must be provided if the heat output of the unit is greater than the cabinet will dissipate. Use the following formula to determine the fan requirement. An allowance has been incorporated into the formula so that the figure for Q is the air delivery in the fan suppliers data.

Page 11: Current Transformer Installation
Current Transformer Installation Current Transformers are supplied seperately and must be fitted externally. The unit has the current transformer (CT) cables pre-installed, colour coding corresponds to the phase wiring identification. Attatch the CT cables to the transformers adhering to the numbering scheme. If the motor overload function is required when the unit is configured for external bypass operation, the current transformer must be placed outside the bypassed circuit. -
Page 12: External Bypass
External Bypass A separate, correctly rated AC53 bypass contactor may be used to provide thyristor bypass . The contactor must be connected in parallel with the synergy™ starter as shown in the diagrams below. Soft-Starting and Soft-Stopping remain active as normal. At the completion of the starting ramp a bypass contactor is closed, effectively removing the thyristors from circuit, which in turn eliminates heating losses. - Page 13 External Bypass Control Circuit Diagrams 3 Wire Control Diagram 110/230Vac control 3 wire Control Diagram 24Vdc control supply supply (U )and digital input (U ) programming. ) and digital input (U ) programming.
