This motor controller, intended to be used with single-phase scroll compressors can limit inrush currents to 40AACrms for RSBS2325A2V.2C24.. and 45AACrms for RSBS2332A2V.2C24..1. Upon applying the control signal, soft starting is achieved within a 600ms interval2. At the end of the soft-start function, the semiconductors are bypassed by electromechanical relays. The device rating is based on a maximum of 12 starts per hr.3
Application of supply voltage is indicated by a green LED in the full ON state. Alarm indication is provided through a red LED which signals the type of alarm via a user friendly flashing sequence.
Delay between starts and/or from stop to start is indicated via an orange LED. Short circuit and Overload protection are not provided with this controller and must be procured separately. Starting and running capacitors are required for controller to operate as intended.
The RSBS can also be supplied with an optional auxiliary alarm relay (Option - V22).
Note: The main and bypass relays may be in an undefined state due to transportation. In case both relays are latched in the ON state, there will be a direct on line start of the compressor - even without control signal. To avoid the direct on line start, the user may do a first power up with no load connected for a period of ≥ 3seconds.
