The APS and ALARM technical outputs will change status into opposite. IV. Acoustic indication will be activated. b) Reconnect the wires in the battery circuit. c) The power supply should return to normal operation, indicating the initial status, within 5 minutes after the battery test is completed. 3. PSU operation indication. 3.1 Optical indication.
www.pulsar.pl 4. Maintenance and operation. 4.1. Overload or short circuit of the power supply output (SCP activation) In the case of short circuit or overload of the power supply, the FAUX fuse becomes permanently damaged. Restoration of the voltage at the output requires fuse replacement 4.2. Protection against reverse battery connection. The power supply unit is protected against reverse battery connection. In the case of incorrect connection the FBAT fuse becomes damaged.
