8 Detailed description
The current relay STW12V operates in the OR circuit.
8.1 Connection of current transducer STWA1(H):
If a current greater than the set value "I" flows through at least one of up to 12 monitored wires, the relay
activates (yellow LED is on).
If the value falls approx. 0.3 A below the inrush current (yellow LED flashes),
the relay switches off again after the delay time set with the " t " adjustment knob has elapsed (yellow
LED goes out).
