8.1.1.3 Operation of 8.5kA Power

Supply for Vertical Magnet Testing


1.0
Purpose and Scope

1.1
The purpose of this Procedure is to provide step by step instruction in the start-up,
operation, and shut-down of the 8.5kA Magnet Power Supply (Supply) during
vertical magnet testing. The Supply is located on the 902 floor along the north
wall.

1.2
The information is provided for authorized operators who will operate the
controls of the Supply.

2.0 Responsibilities

2.1
Authorized operators (Operators) of the Vertical Control Room (VCR) will
perform the procedure described here.

2.2
The Operator shall maintain a Vertical Test log book for the magnet under test.
Entries shall include notes of any irregularities encountered during start-up,
operation, and shut-down of the Supplies.

3.0 Prerequisites

3.1 Training

3.1.1 Operators must be instructed by the Cognizant Engineer responsible for
operation of the Supply, or his designee, before using this Procedure.

3.1.2 Operators must be instructed by the CE/CS responsible for vertical
magnet testing, or his designee, before using this Procedure.

3.1.3 Operator must be a "Authorized Employee" as defined by ES&H
Standards 1.5.1, "Lockout/Tagout Requirements".

3.1.4 Operator must be trained in NFPA 70E Personal Protective Equipment
Requirements and Arc Flash Hazards.

3.1.5 Operator LOTO OJT Training on Power Supply System must be current.

3.1.6 Operator must follow SMD-OPM 8.1.1.44 Generic LOTO Procedure.

3.1.6 Test of Safety Interlock System per OPM 8.1.1.35 shall be completed.

4.0 Precautions

4.1 The output power of this Supply is routed through the Vertical Dewar Link Box
(Link Box). For any changing of links in this box, the 8.5kA power supply must
be locked out and their Kirk keys used to open the Link Box.


4.2 Personal Protective Equipment must be worn as defined in NFPA 70E for
verifying LOTO, 480V is a category 2 hazard. When LED Meter UT-100 and AC
Panel Meters monitoring each AC Phase to ground are installed on the 480V
Disconnect the Hazard Category is reduced to (1), operator can then follow PPE
requirements for the lower classification. (See Section 7.6)

4.2
Contact the CE for operation of the Supply if it is necessary to operate the Supply
in a non-standard manner, which is defined as a manner that deviates from the
procedure described below. Failure to do this could result in injury to personnel
or equipment damage.

5.0 Procedure

5.1 Pre-Operational
Checks

CAUTION

Failure to perform the pre-operational checks could result in equipment
damage.

5.1.1 Check magnet temperature--DO NOT operate above 4.8 degrees K.

5.1.2 Confirm that gas-cooled lead flow is on.

5.1.3 Check that cooling water is flowing to the Power Supply and Magnet Top
Hat Main Leads.

5.2
Configure Link Box

5.2.1 Operator must follow SMD-OPM 8.1.1.44 Generic LOTO Procedure.
Perform Lockout/Tagout. The 480V input disconnect switches for the
8.5kA supply, located on the wall behind the supplies and marked E22-1,
must be locked and tagged.

5.2.2 Open the Link Box by unlocking Kirk locks RE11475 (key #18). The only official copy of this file is the one on-line on the Superconducting Magnet Division
website. Before using a printed copy, verify that this is the most current version by
checking the document issue date on the website.

5.2.3 Make sure that the system is de-energized by using a Fluke T-3 meter or
other passive, low impedance voltage detector (per Lockout/Tagout
training).

5.2.4 Connect the load via the links of the Link Box, securing all nuts.

5.2.5 Close the Link Box. Check that the Kirk Locks are locked. All cover
panels must be installed and secured.

5.2.6 Fill out the Distribution Link Box Status Log Sheet (Attachment1) and
post Status Indicator Card (see Attachments 2 thru 5), describing the
supply configuration, by using the appropriate card and placing it in the
clear plastic envelope affixed to the outside of the Link Box front panel.

5.3
Configure the Remote Control Rack for the 8.5kA Supply

5.3.1 In the rear of the 8.5kA power supply control rack, the following
connections should be made:

A.
P.S. interface cable marked "VERT. DEWAR P.S. INT." to the
"AUX SWITCH PANEL".

B.
Fiber optic cable marked "VERT. C.R." to the VCR fiber optic bus
extender box.

C.
GPIB cable from the fiber optic bus extender box to the current
meter and to the "TEKTRONICS BUCKET".

NOTE No other equipment should be on the bus other than that
described above.

D.
Flip the DOOR INTERLOCK toggle switch, located on the AUX
SWITCH PANEL, to VCR.

5.3.2 Check that control power is applied to the components of the Remote
Control Rack.

5.3.3 Set the Regulator Card (marked "REGULATOR CARD 1"), located in the
8.5kA p.s. control bucket:

A.
Local/Remote switch to Remote.

B.
Rotary switch to position shown on chart depending on magnet
type.

C.
Potentiometer R18 to setting shown on chart depending on magnet
type.

5.3.4 Verify Interface Card is in remote (switch position right).

CAUTION

Do not power up supplies before control software is started.

5.4
Start the Control Software

5.4.1 In the VCR, start the control software on the p.s. control computer.
Confirm that it is operational and that communication with the remote
rack has been established (no bus error messages).

5.5
Power Up Supply Locally

5.5.1 Turn LOCAL/REMOTE switch, located on the control panel on the
outside of the Supply, to LOCAL.

5.5.2 Remove, or have an authorized person remove, locks and tags from input
disconnect switch E22-1. Unlock the Kirk Lock on the switch using key
#18. Put the switch in the ON position.

5.5.3 Place ON/OFF breaker located on the 8.5kA Supply control panel in the
ON position.

5.5.4 Press the RESET button. Check that no fault lights are lit. D.C.
voltmeters and D.C. current meters on Supply should read zero.

5.5.5 Turn the LOCAL/REMOTE switch on the Supply control panel to
REMOTE.

5.6
Before Leaving the Supply Area

5.6.1 Make sure all dewar power connections are covered with rubber
insulating sheets where possible.

5.6.2 Make sure that the gate on the cage surrounding the dewar is shut.
