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
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).
Internal relay outputs (internal IO) is configured with
the following parameters:
Parameter Description Setting range Default value
10.04 K4 function Function of programmable output relay K4.
K5,K6. None, Reset, Enable, Slow speed
forward, Slow speed backward,
Motor heating, Stand still brake,
Start reverse, User defined
protection, Emergency mode,
Fieldbus disable control, Start 1,
Start 2, Start 3 Run
10.05 K5 function Same as K4 function Same as K4 function Top of ramp
10.06 K6 function Same as K4 function Same as K4 function Event group 0
External relay outputs (extension IO) is configured
with the following parameters:
Parameter Description Setting range Default value
11.09 1DO0 function Function of programmable output relay
1DO0 (extention IO). None, Reset, Enable, Slow speed
forward, Slow speed backward,
Motor heating, Stand still brake,
Start reverse, User defined
protection, Emergency mode,
Fieldbus disable control, Start 1,
Start 2, Start 3 Run
11.10 1DO1 function Same as 1DO0 Same as 1DO0 Top of ramp
11.11 2DO2 function Same as 1DO0 Same as 1DO0 Event group 0
11.12 2DO3 function Same as 1DO0 Same as 1DO0 Motor Current (A)
