TAC20 WITH 1014 FAULT

Tac20 system. Not Lon. IOA 6300RE3 mother board. 186o 6300RD3 CPU board. Wont run on car top. Populating 1014 FAULT. Status of INIT SHDN. Turn on car top inspection and manually cycle doors from LD-03 Operator. Turn off inspection. Status changes to SECURITY.

Replaced the 2032 memory battery on the 186o board. No change. Any ideas?

Not TAC20, it’s a TAC20-03. Try a GET command.

Ultimately the Siemens soft starter board was bad. We had an exact issue like this just recently and that was the problem. Only learn that after we replace the CPU board as IMS suggested. Had the same issue just a new CPU board. On a tac 32 had a similar issue recently that was fixed with the other reply of entering get command through IMS
