Delta PSC3 Configuration and SW Upgrade

-48VDC DELTA PSC3 SETTINGS I have come across many problems with new Delta PSU which has been swapped out and not done properly by the external contractors. Tonight just called out to site with similar looking issues which I like to share with you. 1. All the ones I managed to fix are due to the controller not been commissioned properly or not commissioned at all! You need to load the correct configuration files depending on the number of battery strings installed; I have the files and procedure which I will send out later. This will clear many of the alarms. 2. Set the correct number of rectifiers actually installed, this is simply a matter of log in via your PC and change settings under the Rectifier section and save config. 3. Many of you have come across this one whereby if you leave the controller plugged in and fully commissioned the DC power is cut-of completely too all the equipment connected. When you disconnect the controller the power kicks in (a clunk is heard from the solenoid which turns on the power). The reason for this is because the solenoid wires are crossed from factory! Yes hard to believe in fact true, come across 3 sites with this problem. Simply reverse these two black wires on the solenoid and problem solved (see pics) 4. External alarm cables incorrectly connected or not even connected at all, please see pic of how it should be connected and redefine on Node B so that, Port Port Port Port
