6.4 Pressure Protection
Pressure protection uses terminals B23, B24 or C33, C34, C43, C44 on the smart card.
• B23, B24: Use an analog 4–20 mA sensor.
• C33, C34 (low-pressure protection): Use a normally open digital switch sensor.
• C43, C44 (high-pressure protection): Use a normally open digital switch sensor.
Pressure protection is active when the soft starter is in the start, run, or stop mode.
The smart card trips the soft starter when the pressure level passes through the programmed trip level. If the pressure is still outside
the expected operating range when the trip is reset (including auto-reset), the soft starter does not trip again.
