Starter For Auxiliary Motor Fan (Options +M600; What The Option Contains; Description - ABB ACS880-07 Hardware Manual

The output indication of the auxiliary relays can be wired by the customer for example to
•
the main contactor or breaker control circuit of the drive, to open it in case of motor
overtemperature,
•
the appropriate digital input of the drive, to trip the drive and generate a fault message
in case of motor overtemperature, or
•
an external monitoring circuit.
Options +3L514 (3 relays), +5L514 (5 relays) and +8L514 (8 relays) are ATEX-certified
thermal protection functions that have the same external connectivity as +nL506. In
addition, each monitoring relay has a 0/4...20 mA output that is available on the terminal
block. Option +nL514 comes with +Q971 (ATEX-certified safe disconnection function) as
standard and is wired at the factory to activate the Safe torque off function of the drive in
an overtemperature situation. As the monitoring relay does not have a reset functionality,
the manual reset required by Ex/ATEX regulations must be implemented using drive
parameters. For more information, see ATEX-certified motor thermal protection functions
for cabinet-built ACS880 drives (options +L513+Q971 and +L514+Q971) user's manual
(3AXD50000014979 [English]).



What the option contains

The option provides switched and protected connections for 3-phase auxiliary motor fans.
Each fan connection is equipped with
•
fuses
•
a manual motor starter switch with an adjustable current limit
•
a contactor controlled by the drive, and
•
terminal block X601 for customer connections.
The number of connections must be specified when ordering. The maximum number of
connections available depends on the current requirement. The lower current ratings allow
up to four fan connections (eg. option +4M602), while the highest current rating only allows
one (eg. +M610). For more information, refer to ACS-880-X7 single drives ordering
information (3AXD10000052815, available on request).

Description

The output for the auxiliary fan is wired from the 3-phase supply voltage to terminal block
X601 through a motor starter switch and a contactor. The contactor is operated by the
drive. The 230 V AC control circuit is wired through a jumper on the terminal block; the
jumper can be replaced by an external control circuit.
The starter switch has an adjustable trip current limit, and can be opened to permanently
switch the fan off.
