Terminal Function
Description
Terminal F
Fan control
An internal jumper, connected between the fan and
terminal 2 enables three modes of operation (refer to section
5.6 page 51).
For fan power consumption, see technical specification in
section
Terminal 4
Input – STOP command.
•
Input from a N.C. contact
•
To stop the motor, disconnect
Control Input voltage from
terminal 4 for at least
250mSec. (no SOFT STOP)
•
Control Input voltage (STOP, SOFT STOP, START, terminal
inputs 7 and 8) can be the same as Control Supply
(terminals 1, 3) or voltage from a different source.
•
The Control Inputs are opto-coupled and isolated from the
microprocessor circuitry.
Terminal 5
Input – SOFT STOP command
•
Input from a N.C. contact
•
To SOFT STOP the motor
disconnect Control Input
voltage from terminal 5 for at
least 250mS
Control Input voltages available:
QT x xxxx x x 1 x S for 90-230V +10%/-15% 50/60Hz.
QT x xxxx x x 2 x S for 24VDC +10%/-15%.
Terminal 6
Input – START command
.
•
Input from a N.O. contact.
•
To SOFT START the motor,
connect Control Input voltage
to terminal 4 for at least
250mSec.
Terminal 7
Programmable input – Energy
Save / Slow Speed / Reset
Refer to section
Terminal 8
Programmable input – Dual Set
/ Reverse / Reset
Terminal 9
Common to terminals 4-8.
This terminal is a reference for terminals 4, 5, 6, 7 &
8.
Terminal 10
Immediate Relay (N.O.)
Immediate Relay (RUN relay) is the immediate output relay.
•
Voltage free 8A, 250VAC, 2000VA max.
Terminal 11
Immediate Relay (N.C.)
•
The relay is energized upon the START signal.
Terminal 12
Immediate Relay (Common)
•
The relay is de-energized when one of the following occurs:
Fault, Control Supply outage or STOP signal.
•
When SOFT STOP is operated - the relay is de-energized at
the end of the SOFT STOP process.
•
The Immediate Relay (RUN relay) can be used for the
following purposes: Release a brake of a motor, Interlock
with other systems, Signalling, Delay the opening of a line
contactor at the end of SOFT STOP, thus allowing current to
decrease to zero before opening the contactor or to switch
to / from DUAL settings with a time delay from the START
signal (see Special Starting section
•
The relay incorporates ON and OFF delays of 0-3600 sec.
each. Refer to section
4.7.8 page 40 for Relay ON Delay
programming.
Terminal 13
Programmable Fault Output
relay (N.O.)
Voltage free 8A, 250VAC, 2000VA max. changes its position
upon fault.
Terminal 14
Programmable Fault Output
relay (N.C.)
The contact is programmable to function as At Fault
Close
or At Fault Open.
10
If SOFT STOP is not required, connect a jumper between terminals 4 and 5.
11
Motor will start only if STOP (terminal 4) and SOFT STOP (terminal 5) terminals are connected to Control Input voltage.
To reset a fault the START command must be removed.
12
When Control Supply and Control Input voltage are from the same source, connect a jumper between terminals 3 and 9.
