Hi, We have a Mori Seiki Sl-250 Lathe and we have 2 alarms. First one is a 300 APC alarm : Z axis needs zrn. We have no red lights in the Elect cabinet. 2nd is a 24 alarm in the elect cabinet, but the batteries are all good. Machine will not home with these alarms. Our books do not have these alarms in them. Thanks for your time and help. ShawnB
