PROGRAMMING MENU
12D – Slip-Ring Retard
Range:
10% - 90%
Default:
50%
Description:
Sets the level of conduction after the rotor resistance contactor closes, as a percentage of full conduction.
Set so that no current pulse occurs, but the motor retains enough speed to start correctly.
15 Advanced
15A – Access Code
Range:
0000 - 9999
Default:
0000
Description:
Sets the access code to control access to restricted sections of the menus.
Use the and buttons to select which digit to alter and use the and buttons to change the value.
NOTE
In the event of a lost access code, contact your supplier for a master access code that allows you to re-program a new
access code.
15B – Adjustment Lock
Options:
Read & Write (default) 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.
Description:
Selects whether the keypad will allow parameters to be changed via the Programming Menu.
NOTE
Changes to the Adjustment Lock setting take effect only after the Programming Menu has been closed.
15C – Emergency Run
Options:
Disable (default)
Enable
Description:
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.
CAUTION
Continued use of Emergency Run is not recommended. Emergency Run may compromise the starter life as all
protections and trips are disabled.
Using the starter in 'Emergency Run' mode will void the product warranty.
15D – Shorted SCR Action
Options:
3-Phase Control Only (default)
PowerThrough
Description:
Selects whether the soft starter will allow PowerThrough operation, if the soft starter is damaged on one phase.
The soft starter will use two-phase control, allowing the motor to continue operating in critical applications.
• PowerThrough is only available with in-line installations. If the starter is installed inside delta, PowerThrough
will not operate.
• PowerThrough remains active until '3-Phase Control Only' is reselected.
• A shorted SCR or a short within the bypass contactor will trip the starter on ‘Lx-Tx shorted’. If PowerThrough is
enabled, the trip can be reset and subsequent starts will use PowerThrough two-phase control; however not all
features will be available. The trip LED will flash and the display will indicate ‘2 Phase - Damaged SCR'.
CAUTION
PowerThrough uses a two-phase soft start technology and additional care is required when sizing circuit breakers and
protection. Contact your local supplier for assistance.
CAUTION
The starter will trip on Lx-Tx Shorted on the first start attempt after control power is applied. PowerThrough will not
operate if control power is cycled between starts.
