Indication Description Remarks
Terminal 16 Programmable End of
Acceleration (Run) Output relay
(N.O.)
Voltage free 8A, 250VAC, 2000VA max. changes its
position at the end of acceleration, after an
adjustable time delay (Contact Delay), 0 – 120 sec.
Terminal 17 Programmable End of
Acceleration (Run) Output relay
(N.C.)
The contact returns to its original position when
ENERGY SAVE is operated, on SOFT STOP or
STOP signals, on FAULT condition, or upon voltage
outage.
Terminal 18 Programmable End of
Acceleration (Run) Output
relay (Common)
The End of Acceleration contact (Run) can be used
for:
• Closing a bypass contactor
• Activating a valve after compressor has reached full
speed
• Loading a conveyor after motor reached full speed.
Refer to section
7.7.3 page 72 for RUN CONTACT
DELAY programming
Terminal 19 External Fault input Input from a N.O. contact that is connected between
terminals 19 and 21. The RVS-DN will trip 2 seconds
after the contact closes.
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 the Insulation
Alarm option.
• 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 RVS-DN operation, and cause RVS-DN or
motor damage.
• Refer to section
4.12 page 24 for the External Fault
wiring diagram.
Terminal 20 Tacho Feedback input (optional)
• Provides linear acceleration and deceleration.
• Requires high quality tacho generator on motor
shaft, output voltage 0-10VDC, linear
speed/voltage ratio.
• Consult factory for further information before using
the tacho feedback feature.
Terminal 21 Neutral connection When a mains neutral wire is available, connect
terminal 21 to neutral. Terminal 21 serves only as a
voltage reference to the control circuitry.
Notes:
• RVS-DN circuitry incorporates an internal artificial
neutral, which should only be used, when the
system is not grounded and mains neutral
connection is not available.
• 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 RVS-DN operation, and cause RVS-DN or
motor damage.
• Refer to section
1 4.1 on page 19 for terminal 21
connection.
