Hello PM community,
My old 1983 Citizen Cincom F12 went off-line recently and I am seeking help from people like myself who are big fans of this machine.
[Please pardon me as I know my issue description will be a bit "wordy".]
In the past couple years my machine has run without issue for several hundred hours, but the other day upon power up drew a:
"SYSYEM ALARM: NO.3", "PROGRAM MEMORY: PARITY HIGH" message, and the servos and hydraulics do not come on. With a little research I tried the suggested fixes of:
1) Depress "Power On" button while depressing the "Delete key only". [Worked for someone - erased only all their programs - did nothing for me.]
2) Depress "Power On" while holding in "Cancel and Delete keys". [No change.]
and finally,
3) Depress "Power On" while holding "Delete and Reset keys" with the "Parameter Switch" inside the cabinet set to "On".
This of course cleared all my programs, parameters (of which I have copies), and offsets, and left me with a new screen showing: "ALARM MESSAGE" (with no alarm number and the red "N/C Alarm" button on the operator's panel NOT lit.), and with the words "NOT READY" message flashing - but otherwise no change.
I removed the cover under the #1 turret in order to hold the switches open while powering up as was also suggested... no success. (This was meant to be a fix if the red N/C Alarm button had been on and flashing... but I'm trying anything and everything I can at this point.)
I did find and replace a small green 1amp fuse that had blown (located amongst the relays inside the operators control panel), but still no luck.
In one post someone stated that if the above mentioned reset methods where unsuccessful, the problem could be: 1) A Memory Problem; 2) A Master PCB issue; or 3) The Power Supply (in which they noted to check the power supply voltages, especially the 5VDC).
Although I'd worked on this exact series of machine way back when they were new, I'm not very knowledgeable when it comes to their circuitry and how to diagnose electrical problems.
From past experience I know how helpful and knowledgeable "Practical Machinist" members can be... any words of wisdom would be greatly appreciated.
Thank you in advance.
