The softstarter has three programmable output relays that
can be used for different purposes depending on the selected
function, independently of each other.
Relay K4 has default setting Run, relay K5 has default setting
Top of Ramp and relay K6 has default setting Event.
Run signal is given during start ramp, running, and stop ramp
if used. Can be used to control the line contactor.
Top of Ramp signal is given when full voltage to the motor is
applied. Can be used to control an external by-pass
contactor.
The event function has several alternatives that can be
switched On/Off as required.
One, several or all indications can be used individually,
independently of each other at the same time for each output
relay.
