Bypass
on
Fault.
Bypass
Mode
on
Fault
is
enabled
by
setting
parameter
P8
‐
11=1
(enabled).
Once
enabled
the
drive
will
switch
to
bypass
mode
in
the
event
of
a
trip
or
fault
occurring
on
the
drive.
When
a
trip
occurs
the
drive
will
immediately
open
the
drive
output
contactor
(drive
output
already
disabled
due
to
trip),
wait
a
time
(defined
by
P8
‐
13)
and
then
close
the
bypass
contactor.
The
motor
will
remain
under
Bypass
control
until
the
enable/run
input
is
removed
from
the
drive
(drive
control
terminal
2)
at
which
point
the
Bypass
contactor
will
be
opened.
When
the
run/enable
input
is
closed
again
the
drive
will
attempt
to
run
under
drive
control
(drive
output
contactor
closed).
It
is
required
that
Spin
Start
(P2
‐
26)
be
enabled
for
this
function.
Bypass
on
Fire
Mode.
Bypass
on
Fire
Mode
is
enabled
by
setting
parameter
P8
‐
12=1
(enabled).
Once
enabled,
the
drive
will
switch
to
bypass
mode
in
the
event
of
the
fire
mode
input
becoming
active
(true).
Fire
Mode
should
be
configured
(see
section
13.8.
Fire
Mode
Function)
and
an
input
assigned
either
through
parameter
P1
‐
13
or
through
menu
9
(P9
‐
32)
prior
to
enabling
Bypass
on
Fire
Mode.
When
the
Fire
Mode
input
becomes
true
the
drive
will
immediately
disable
its
output
and
open
the
drive
output
contactor,
wait
a
time
(defined
by
P8
‐
13)
and
then
close
the
bypass
contactor.
The
motor
will
remain
under
bypass
control
until
the
fire
mode
input
is
deactivated.
When
the
Fire
Mode
input
is
deactivated
the
bypass
contactor
will
be
opened,
there
will
be
a
short
delay
(defined
by
P8
‐
13)
and
the
Drive
Output
contactor
will
close.
Provided
the
enable
input
is
still
present
then
the
drive
will
take
over
operation
of
the
motor.
It
is
required
that
Spin
Start
(P2
‐
26)
be
enabled
for
this
function.
Bypass
on
Input
Bypass
mode
on
Input
is
enabled
by
assigning
a
bypass
trigger
input
in
menu
9.
Set
parameter
P9
‐
13
(Bypass
Trigger
Input)
to
one
of
the
available
digital
inputs.
Once
an
input
is
assigned
the
drive
will
switch
to
bypass
mode
in
the
event
of
that
input
becoming
active
(true).
When
the
bypass
trigger
input
becomes
true
the
drive
will
immediately
disable
its
output
and
open
the
drive
output
contactor,
wait
a
time
(defined
by
P8
‐
13)
and
then
close
the
bypass
contactor.
The
motor
will
remain
under
bypass
control
until
the
bypass
trigger
input
is
deactivated.
When
the
bypass
trigger
input
is
deactivated
the
bypass
contactor
will
be
opened,
there
will
be
a
short
delay
(defined
by
P8
‐
13),
the
Drive
Output
contactor
will
close
and
the
drive
will
take
over
operation
of
the
motor.
If
the
enable
input
is
removed
from
the
drive
then
the
drive
will
switch
off
whichever
of
the
two
output
contactors
is
currently
on.
When
the
drive
is
re
‐
enabled
the
drive
will
look
at
the
status
of
the
bypass
input
to
determine
which
of
the
output
contactors
to
operate.
It
is
required
that
Spin
Start
(P2
‐
26)
be
enabled
for
this
function.
In
all
modes
of
operation
the
time
period
between
one
of
the
output
contactors
switching
off
and
the
other
switching
on
is
defined
by
parameter
P8
‐
13
(Bypass
Contactor
Changeover
Time).
This
parameter
should
be
set
with
a
value
that
ensures
the
first
contactor
has
time
to
clear
prior
to
an
attempt
being
made
to
switch
in
the
second
contactor.
Additional
mechanical
or
electrical
inter
‐
locking
should
also
be
provided.
The
Drive
OLED
display
will
show
the
following
indication
whenever
bypass
mode
is
activated
by
the
Optidrive
HVAC
control.

13.8.
Fire
Mode
Function
The
Fire
Mode
function
is
designed
to
ensure
continuous
operation
of
the
Optidrive
HVAC
until
either
the
Fire
Mode
input
is
removed
or
the
drive
is
no
longer
capable
of
sustaining
operation.
It
is
used
in
applications
where
an
input
is
provided
to
the
drive
from
a
fire
control
system
in
the
event
of
a
fire
in
the
building
and
drive
operation
is
required
to
be
maintained
for
the
longest
possible
period
in
order
to
clear
smoke
or
maintain
air
quality
within
that
building.
Operational

The
Fire
Mode
function
is
a
dedicated
digital
input
function
within
the
Optidrive
HVAC
control
software.

input
can
be
assigned
to
activate
the
drive
Fire
Mode
function
in
one
of
the
following
ways:
