7.12.2 Relay outputs
The softstarter is equipped with three relay outputs for a
configurable output signal depending of selected function.
The relay outputs are, K4, K5 and K6. The relays outputs
are; 30VDC/250VAC Ith = 5A , Ie= 1,5Amp (AC-15).
The relay opens and closes depending on set
configurations. All relay outputs are programmable.
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 outpt.
• 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 – TBD
• Sequence 1-3 TOR – TBD
• Run reverse – TBD
As default K4 is configured to function Run, K5 to Top of
ramp and K6 to Eventgroup 0.
Description of the relay terminals
7
Each relay has three terminals, one common terminal
(COM), one normally open terminal (NO) and one normally
closed terminal (NC). See Figure 84.
Common – TBD
Normally open – Circuit is open in normal mode (circuit
is not shorted to common).
Normally closed – Circuit is in normal mode (the circuit
is continuously shorted to common).
