7.12 Restricted Parameters
15-1 Access Code
Range:
Function:
0000
*
[0000 -
9999]
Sets the access code to enter the simulation
tools and counter resets or the restricted
section of the Programming Menu (parameter
group 15 and higher).
Use [Back] and [OK] to select which digit to
alter and use [
▲
] and [
▼
] to change the value.
NOTE
In the event of a lost access code, contact
your supplier for master access code that
allows you to re-program a new access
code.
15-2 Adjustment Lock
Option:
Function:
Selects whether the LCP will allow parameters to
be changed via the Programming Menu.
Read &
Write
*
Allows users to alter parameter values in the
Programming Menu
Read Only
Prevents users altering parameter values in the
Programming Menu. Parameter values can still be
viewed.
No Access
Prevents users adjusting parameters in the
Programming Menu unless an access code is
entered.
NOTE
Changes to the Adjustment Lock setting take
effect only after the Programming Menu has
been closed.
15-3 Emergency Run
Option: Function:
Selects whether the soft starter will permit emergency
run operation. In emergency run, the soft starter will
start (if not already running) and continue to operate
until emergency run ends, ignoring stop commands and
trips.
Emergency run is controlled using a programmable
input.
When Emergency Run is activated in internally bypassed
models which are not running, the starter will attempt a
normal start while ignoring all trips. If a normal start is
not possible, a DOL start via the internal bypass relays
will be attempted. For non-bypassed models, an
external emergency run bypass contactor may be used.
15-4 Current Calibration
Range:
Function:
100%
*
[85%
-
115%]
Motor Current Calibration calibrates the soft
starter's current monitoring circuits to match an
external current metering device.
Use the following formula to determine the
necessary adjustment:
Calibration ( % ) = Current shown on MCD 500 display
Current measured by external device
e.g. 102 % = 66 A
65
A
NOTE
This adjustment affects all current-based
functions.
15-5 Main Contactor Time
Range:
Function:
400
msecs
*
[100 -
2000 msecs]
Sets the delay period between the
starter switching the main contactor
output (terminals 13, 14) and
beginning the pre-start checks (before
start) or entering the not ready state
(after a stop). Set according to the
specifications of the main contactor
used.
15-6 Bypass Contactor Time
Range:
Function:
150 msecs
*
[100 - 2000
msecs]
Sets the starter to match the bypass
contactor closing time. Set according
to the specifications of the bypass
contactor used. If the time is too
short, the starter will trip.
15-7 Motor Connection
Option:
Function:
Selects the soft starter will automatically detect
the format of the connection to the motor.
Auto-Detect
*
In-line
Inside Delta
15-8 Jog Torque
Range:
Function:
50%
*
[20% - 100%] Sets the torque level for jog operation.
See the section
Jog Operation
for more
details.
NOTE
Setting this parameter above 50% may cause increased
shaft vibration.
