This VME crate and its power supply were manufactured
with special +-5V Analog power supplies instead of the
normal +-12V VME supplies.  These +-5V Analog supplies
used the VME +-12V distribution bus lines in the backplane.
All of the Wiener power supply chassis that I have left
at MSU were built this way.

In the power supply chassis that I'm shipping to you I have
removed the special +-5V Analog supplies and installed the
normal  +-12V supplies   (along with the high current +5V
and +3.3V digital supplies that are used in VME-64x crates).

This power supply chassis is setup with the following Wiener
DC power modules:

  VME +5V     Wiener U0 supply    type MEH     5V  115 Amp

  VME +3.3V   Wiener U3 supply    type MEH   3.3V  115 Amp

  VME +-12V   Wiener U1/U5 supply type MDL  +-12V   11 Amp


I believe that this set of DC power modules should match
the other HAWC Wiener VME crates.

I setup all 4 of these supplies in the default way that
Wiener typically delivers their VME crate power supplies,
i.e.  the Voltage Monitor (Umon) limits are  95% to 105%
of the nominal output and the SCR Crowbar (OVP) limit is 125%.

  - If the crate's built in monitoring system detects a
    supply output outside of its upper and lower Voltage
    Monitor (Umon) limits then it turns OFF that DC power
    module.

  - If the crowbar circuit inside of the DC power module
    itself detects the the module output above the OVP
    limit then it triggers the SCR crowbar to short circuit
    the output of that module.

I have tested the Umax and OVP limits on the +-12V MDL
DC power module that I installed in the power supply chassis.
I ran and checked all 4 of the supplies under load.

I labeled the test points for measuring these VME Bus
voltages on the back side of the backplane if you want
to check them.  Measuring on the back side of the
backplane eliminates the risk of damaging a backplane
connector by trying to plug a meter test probe into it.

This power supply chassis does have Wiener's  MNPFC-16

I shipped an instruction book and a power cord with this
Wiener VME Crate.   If you are doing your own maintenance
I have the more technical service manual for these crates.
