If start assist is required, in case of operating
below the nominal voltage, a CSR starting device
is required.
During start-up, the start winding (C-S) is
energised through an electromagnetic potential
relay and a start capacitor.
A permanent (run) capacitor is wired between
the start winding (C-S) and the run winding (C-R). CSR wiring
Danfoss scroll compressors are designed to
operate without any assistance if running within the defined nominal voltage. PSC wiring is
sufficient (see below).
The start winding (C-S) of the motor remains in
circuit through a permanent (run) capacitor.
This permanent (run) capacitor is connected
between the start winding (C-S) and the run
winding (C-R).
