Basic Starting Keypad – Allows motor starting and stopping by pressing Start/Stop key on keypad.
Remote – Allows motor starting and stopping by applying or removing 115VAC at
terminals S0 and S1 of the control board.
Start Pedestal Start Pedestal Voltage – end of stop smoothing and beginning of low voltage ramp to
zero volts (if low voltage ramp is active).
Start Time Number of seconds after the 3 cycle power–up to full motor voltage.
Stop Pedestal Stop Pedestal Voltage is the percentage of line voltage applied to the motor after a stop
command.
Stop Time Time in seconds after a stop command to ramp down the motor voltage (Stop Time 1 or
2). Stop Time 1 with low voltage ramp active. Stop Time 2 with no low voltage ramp.
Current Limit Percentage of running current (P24 and P25). Adjustable from 100 – 800%.
Power on
Parameter
Resets all parameter values to the values at the most recent power up. Display blinks
twice to confirm reset is complete.
Protection Full – provides shorted SCR protection during start and run, single phase protection
during start, optimizing not selected.
Full + Optimise – provides shorted SCR protection during start and run, single phase
protection during start, optimizing is selected.
Start + Bypass – provides shorted SCR protection during start, single phase protection
during start, optimizing not selected and no single phase protection during run.
This mode must be used with top of ramp bypass contactor.
Phase Loss only – shorted SCR protection during start and run is disabled, single phase
protection during start, optimizing not selected.
This mode is recommended when input power noise frequently causes nuisance trips.
