Control Terminals
6
Fault Contact Terminals 13-14-15
Terminals: 13-N.O. 14-N.C. 15 – Common.
Voltage free 8A, 250VAC, 2000VA max. changes its
position on fault. The contact is programmable to
function as Trip or Trip – fail safe relay.
a.When Trip
function is selected, the relay is
energized upon fault. The contact returns to its
original position after fault has been removed and
starter was reset, or upon disconnection of Control
Supply.
b.When Trip-fail safe
function is selected, the
relay is energized immediately when Control
Supply is connected and de-energizes upon fault
or Control Supply disconnection.
End of Acceleration Contact Terminals 16-17-18
Terminals: 16-N.O. 17-N.C. 18 – Common.
Voltage free 8A, 250VAC, 2000VA max. changes its
position at the end of acceleration, after an adjustable
time delay (Contact Delay), 0 – 120 sec.
The contact returns to its original position, when
Energy Saver is operated, on Soft Stop or Stop signals,
on fault condition, or upon voltage outage.
The End of Acceleration contact can be used for:
• Closing a by-pass contactor.
• Activating a valve after compressor has
reached full speed.
• Loading a conveyor after motor reached full
speed.
External Fault Terminal 19
Input from a N.O contact, connected between terminals
19 and 21. The starter will trip 2 sec. after contact
closes.
WARNING
• Only potential free contacts may be
connected to terminal 19.
• Do not connect any voltage to terminal 19.
Any connection of voltage to this terminal
may disrupt soft-starter operation, and cause
starter or motor damage.
Notes:
• Wires connecting the External Fault contact to
terminal 19 should not exceed 1 meter in
length.
• External Fault can be used only when terminal
21 is connected to Neutral or Ground.
• Do not use External Fault while using
Insulation Alarm option.
Tacho Feedback – Optional Terminal 20
Provides linear acceleration and deceleration.
Requires high quality Tacho generator on motor shaft,
output voltage 0-10VDC, linear speed/voltage ratio.
Consult factory before using Tacho feedback feature
for further information.
Neutral Terminal 21
When Neutral wire is available, connect Terminal 21 to
Neutral (see pages 6, 8 & 10). Terminal 21 serves only
as voltage reference.
Note: Starter’s power section incorporates and internal
artificial neutral, which should only be used,
when the system is not grounded and neutral
connection is not available.
WARNING
• Only potential free contacts may be connected to
terminal 21.
• Do not connect any voltage to terminal 21.Any
connection of voltage to this terminal may disrupt
soft-starter operation, and cause starter or motor
damage.
Notes:
• Wires connecting between terminal 21 and
terminal 19 should not exceed 1 meter in
length.
• Do not use External Fault when terminal 21 is
not connected to Neutral or Ground.
Terminal 21- Connections with various mains.
