Terminal
Terminal F Fan control
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)
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
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
Terminal 8 Programmable input – Dual Set
/ Reverse / Reset

If SOFT STOP is not required, connect a jumper between terminals 4 and 5.
10
Motor will start only if STOP (terminal 4) and SOFT STOP (terminal 5) terminals are connected to Control Input voltage.
11
To reset a fault the START command must be removed.
When Control Supply and Control Input voltage are from the same source, connect a jumper between terminals 3 and 9.

.
11
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 3 page 11.
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.
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%.
Refer to section 4.7.8.1 page 41.
This terminal is a reference for terminals 4, 5, 6, 7 &
8.
Immediate Relay (RUN relay) is the immediate output relay.
• Voltage free 8A, 250VAC, 2000VA max.
The relay is energized upon the START signal.
•
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 6.2.3.1 page 57).
• 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.
Voltage free 8A, 250VAC, 2000VA max. changes its position
upon fault.
The contact is programmable to function as At Fault
Close or At Fault Open.
