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

You probably need to reference the turret and the step by step instructions are written below. If you are familiar with this control, you need to get the turret indexed and clamped on station 12, turn parameter write on, change Keep relay K0.6 to a 1, turn the turret selector switch to station 12, select reference return mode, and hold the turret index button for more than 2 seconds (note: the turret does not index). Turn Keep relay K0.6 back to a 0, turn parameter write off, and you are done. What this does is set the bits in the software to station 12. Then index the turret to make sure the stations are correct.

You can try replacing teh relay on the relay board, it could be a "sticky" relay
