Information
Programmable output
The programmable output relay (terminals COM1, RLO1) can be used to signal either trip or run status. This
relay is normally open.
Trip:
The relay closes when the Digistart CS trips. The relay can be used to operate the shunt-trip mechanism of
an upstream circuit breaker (in order to isolate the motor branch circuit), or to signal the trip to an automation
system or externally. The relay will open when the trip is reset.
Run:
The relay operates when the soft start is complete, the bypass relays are closed and full voltage is being
applied to the motor. The relay can be used to operate a contactor for power factor correction capacitors, or
to signal soft starter run status to an automation system.
4.1.6 Semiconductor fuses
Semiconductor fuses can be used with Digistart CS soft starters to reduce the potential for damage to SCRs
from transient overload currents and for Type 2 coordination. Digistart CS soft starters have been tested to
achieve Type 2 coordination with semiconductor fuses. Suitable Bussman and Ferraz semiconductor fuses
are detailed below.
