10.21 Parameter Group 33-** Pressure Control

The parameters in this group are only active if a smart card is installed.
Pressure control uses terminals B23, B24 on the smart card. Use an anlog 4–20 mA sensor.
Table 223: 33-1 - Pressure Control Mode
Option Function
Selects how the soft starter uses data from the pressure sensor to control the motor.
* Off The soft starter does not use the pressure sensor to control soft starting.
Falling Pressure The soft starter starts when the pressure drops below the level selected in parameter 33-2 Start Pressure
Start Level.
Rising Pressure The soft starter starts when the pressure rises above the level selected in parameter 33-2 Start Pressure Lev-
Start el.

Range Function
* 5 1–5000 Sets the pressure level to trigger the soft starter to perform a soft start.

Function
Sets a delay before a low-pressure protection trip can occur. The delay is counted from the time a
start signal is received. The pressure is ignored until the start delay has elapsed.
Function
Sets a delay between the pressure passing the low-pressure trip level and the soft starter trip-
ping.
Function
Sets a delay between the pressure passing the pressure control start level and the soft starter per-
forming a soft start.
Function
Sets the pressure level to trigger the soft starter to stop the motor.
