7.14.3 Relay outputs
The Softstarter has 3 relay outputs. The relay outputs are
K4, K5 and K6. The relays outputs are: 30VDC/250VAC
Ith = 5A , Ie= 1,5Amp (AC-15).
You can set the function of these relay output signals
Functions or an event group can be related to the
physical signal through a drop down menu on the HMI.
The programmable options for each relays are:
• None – No function on the relay output.
• Run – Indicates when the Softstarter gives voltage to
the motor.
• Top of ramp (TOR) – Indicates that motor runs on full
voltage.
• Event group (0-6) – Faults, protections, warning are
all selectable by customer.
• Sequence 1-3 Run – Used to control the line
contactors during sequence start.
• Sequence 1-3 TOR – Used to control the bypass
contactors during sequence start.
• Run reverse – Used to close the reversing contactor.
As default K4 is set to function Run, K5 to Top of ramp
and K6 to Eventgroup 0.

Description of the relay terminals
Each relay has 3 terminals: 1 common terminal (COM),
1 normally open terminal (NO) and 1 normally closed
terminal (NC). . See Figure 7.8 .
Normally open – Circuit is open in normal mode (circuit is
not shorted to common).
Normally closed – Circuit is closed in normal mode (the
circuit is continuously shorted to common).
Internal relay outputs (internal I/O) have these parameters:
Parameter
10.04 K4 function
10.05 K5 function
10.06 K6 function
External relay outputs (extension I/O) have these
parameters:
Parameter
11.09 1DO0 function
11.10 1DO1 function
11.11 2DO2 function
11.12 2DO3 function
