3.3 Error acknowledgment
There are three ways to acknowledge a fault:
1. Manually, using the Reset button
Pressing the Reset pushbutton on the front of the device will acknowledge
an error/fault. If the Reset button is still being held down after approx. 2
seconds, the electronic motor starter will reassume its error condition.
If the acknowledgment request is present (Reset button held down) for more
than 6 seconds, an extended power output stage test will be run.
2. Manually with a remote acknowledgment
A remote acknowledgment control section can be implemented with the
SmartWire-DT system by setting output bit 0.2 (RES_MAN).
An acknowledgment will be triggered as soon as a change in bit state from 0
to 1 is detected via SmartWire-DT. If a change in bit state from 1 to 0 is not
detected after approx. 2 seconds have passed, the electronic motor starter
will reassume its error condition, since tampering, or a defect in the
acknowledgment circuit, cannot be ruled out.
