I have a Miyano BND34S that will not power up the hydraulic pump when the machine come online. Machine is "ready", and the axis' can be zeroed out. Diagnostics show an alarm in 300 bit 1. Any ideas where the alarm is being generated, or how to overrride?

Is there a description with the alarm or an alarm number? Will it not run in auto mode? Could be something as simple as waylube oil. I have not experienced this but I have heard on some of the older controls that when the waylube is low there is no specific alarm but the machine won't run in auto.

Make sure none of your overloads have tripped on the contactors

Checked the contactor for the hyd pump... it wasnt tripped, but when I manually slid the mechanism over (it has an "on/off" position switch), it held and the pump is now on. Weird... I think the alarm had to do with the turret clamp timer.
