Immediate/Shear-pin Relay.........Terminals 10-11-12
Terminals: 10-N.O. 11-N.C. 12 - Common.
Voltage free 8A, 250VAC max.
Selection between functions is made from the keypad or
through the communication, (see I/O Programming),
Programmable functions:
1. Immediate (after start signal)
2. O/C Shear-pin detection.
1. When Immediate is selected, the contact
changes its position upon start signal. The
contact returns to its original position upon Stop
signal and in case of a fault or control supply
outage.
When Soft Stop is operated, the contact returns to
the original position at the end of the Soft Stop
process.
The contact incorporates On & Off delays within
0 – 60 sec each.
The Immediate Contact can be used to:
• Interlocking with other systems.
• Signaling.
• Delay for opening an upstream contactor at the
end of soft stop thus to allow current decrease
to zero before opening the contactor.
• Switch to / from Dual Adjustment settings with
a time delay from Start signal (see Special
Starting).
2. When O/C Shear-pin is selected, the contact
changes position upon detection of Jam
condition (Starter trip can be delayed within 0-5
sec.)
The O/C Shear-Pin contact can be used to:
• Interlocking with other systems.
• Signaling
• Delay for operating a reversing combination of
contactors when Jam is detected to allow a
clearing of a Jam condition.
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 with an adjustable
time delay (Contact Delay) of 0 – 120 sec.
The contact returns to its original position on Soft Stop
or Stop signals on fault condition or voltage outage.
The End Of Acceleration contact must be used to close a
by-pass contactor through a pilot (interposing) relay and
can be use to:
• Activate a valve after compressor has reached
full speed.
• Signal, allowing for the loading of a conveyor
after motor reached full speed, etc.
External Fault 1 ...................................... Terminal 19
Input from a N.O contact connected between terminals
19 and 21. The starter will trip 2 seconds after contact
closes.
External Fault 2 ...................................... Terminal 20
Input from a N.O contact connected between terminals
20 and 21. The starter will trip 2 seconds after contact
closes.
Common B................................................ Terminal 21
Common for terminals 19, 20
Notes:
1. When Control Supply voltage and Control Input
voltage are from the same source, connect a
jumper between terminals 3, 9 and 21.
2. If External inputs are not used, leave terminals
19, 20 and 21 open.
