>>> 'sink12' problem from bob -- Mon Jan  9 14:51:04 1989 <<<

The float assembly on sink12 has been replaced. I used the last spare
float assembly to complete this repair. 
sink12 is up for use.

The floats on sink12 dumped the vacdrains. All floats were in their
lowest position and when the unit was moved ~1 inch the drain reset
to the proper position. Pins in the connector are a prime suspect
of failure and will be replaced.

Replaced female pins in AMP connector. 
The floats failed to fail 20 0f 20 attempts.

P: FPL as reported by Marilyn.
S: No trouble found. The sludge that is usually present in
   this sink, and that usually causes the drain problem,is
   not a problem this time.

house air pressure problems.

I've notified Phil of the problem.

>>> 'sink12' problem from phillip -- Mon Aug 28 06:53:44 1989 <<<

P: FPL on this sink while aptchrome running.
S: No apparent failure on this sink that caused the problem.
   The vac. drain sensor history indicates there is a problem
   with something in the vacuum make-up equipment.
   This will be explored.

>>> 'sink12' problem from marilyn -- Wed Oct  4 08:29:25 1989 <<<

Problem: Full plenum lockout; alarm was silenced, then it came

P: PLenum leak (?) per Marilyn.

   all plumbing connections upon reassembly. The plenum

Problem: sink12 does not enable on the taurus (green light stays off.)

>>> 'sink12' problem from evan -- Fri Mar  2 16:12:33 1990 <<<

The taurus enable cable is working for sink12.  The enable light does not light
because the ac power to sink12 (and the hepa lights) is off during a repair.

>>> 'sink12' problem from phillip -- Mon Mar  5 06:50:25 1990 <<<

P: No taurus lamp lit when enabled.
S: Found power switch on sink off. Restored switch.
