So the unit doesn’t run on inspection either I presume.
You have all the safety inputs GV, HS, CS, ICS, DRVS, CEN (possibly more) etc to actually run the unit if it were possible.
MF+ and GF+ standby voltage is present?
All breakers on the control panel are good (at a measuring point, not just “on”).
DC loop is not tripped?
Any information on what TF (tach Fault?) or F means?
Short of assistance here on the site, this person at MILTRONICS who has posted under most Swift problems give a phone number for technical support. Might be worth a try. No screen to see faults or I/O’s can be tough.
Good luck.
