Compressor Restart

First start by locating the page below through the compressor logger web page. This
page MUST be access behind the Lowell Firewall either on the local network or through
the VPN.

http://compressor.lowell.edu/current-values-control.htm

The Current Probe Point Values Section

There are two sections in the page. The first section of this page
is the current values of the various inputs to the logger. The important
ones to look at here are the Fan, the Cold Head current, and the
Comp. Temp. If the compressor is not running the current values will be
zero or very close to zero.

NOTE: if the compressor temperature or Comp. Temp is above 105 this means
that the compressor is likely in a over temperature state. The compressor
must cool before a successful restart is possible.

The Remote Control Section.

The remote control section should appear as it does in this attached panel.
The main thing to notice is the state of the Compressor ROCB. This switch
is attached to a form C relay controlling the remote operation circuit breaker
or ROCB. When the switch is set to high that means that the relay is
energized and the breaker is in the on position. If it is in the low
position it just means that the relay is not energized and the ROCB
could be either in the on or off position.

Restarting the Compressor.

Once it has been verified that the compressor is not running and the
relay in not energized. Energize the relay by clicking the Compressor ROCB
high radio button and then click the button "Update Logger with new settings".
After refreshing the page you should see the current values at the normal
above .5 A which will mean that the compressor is operating normally.

If the relay is energized you will need to de-energize it and energize
it again by toggling the radio buttons low then high.

NOTE: I would prefer to keep the relay not energized so please notify
Dan Clemens or Brian Taylor that you have restarted the compressor with
the ROCB. One of us will reset the ROCB by hand.
