Hello,
I have a GS 250L Hardinge Lathe and I am getting alarms on the Turret. The alarms are 1001 (Turret Servo Alarm) and 1015 (Turret Not Clamped). The alarms come on when I first turn the machine on. Reset will not clear the alarm, what I have to do to clear the alarm is hit the reset button, the manually activate the spool valve in the back of the machine. This will clear the 1015 alarm. Then I reset breaker QBF4, this will clear the 1001 alarm. When I go to do a tool change, the alarms come up again. At first i was thinking that this was a sticky spool valve, but when I manually activate the spool valve with out hitting reset, it goes back into the same position, so now I am wondering if it is not the electrical valve that sits on top of it.
The machine was manufactured in 2007, any help would be greatly appreciated!
Thank You
Mike
