 | Operational Policies
 | 1)  The rotary service switch must be set to "repair" before any repair.
 | 2)  The rotary service  switch must be set to "maintenance" before all maintenance tasks.
 | 3)  The down time clock should be incremented if the turbine is braked due to a malfunction.  The WTG is not safe to operate.
 | 4)  The System OK time clock should be incremented in one of three scenarios.  First, if the turbine has a minor malfunction
 | that needs correcting but is not serious enough to require turbine braking.  Second, the turbine is automatically changing
 | state as per approved design.  The turbine may not produce power during this scecario but the duration is short.
 | Third, a technician pauses or stops a turbine, that is safe to operate, for a short time duration for inspection or testing.
 | Beyond this short duration the technician will either manually induce a fault to increment [NAME] time,
 | will set the rotary switch to "repair", or will set the rotary switch to "maintenance".
List of Messages:  For status messages indicated with "A" in the Auto Reset Column, a restart automatically follows resolution of the cause of error.  When a number is given, an automatic restart follows resolution of the cause of error; however, if this number of disturbances is exceeded, the turbine remains braked.
