ENGAGEMENT OF ITA WITH RECEIVER
Listed below are the required steps to be taken prior to the engagment of the ITA and receiver.
•Prior to engaging an ITA with the receiver for the rst time, the user may nd it to be good practice to check to see if all the modules
(ITA and receiver) have been installed properly. This would involve the inspection of the module ends - ensuring the even height of all
module ends relative to one-another. While checking this, the user should verify the positioning of the modules themselves. It is crucial
for all modules to be installed properly. Install modulues such that Pin 1 is located at the
top of the ITA/receiver frame.
Improper installation will cause damage to the modules, and possibly to the ITA and/
or receiver. All ITA modules have to match the receiver modules. This means that upon
engaging, an ITA module will mate with its respective receiver module (Power ITA to mate
with Power receiver, etc.).
•To secure the receiver to the plug and play plates/rack system, the two top latches on
the receiver (one on each side) should be locked into the hooks on the plug and play
plate/rack system. The two top latches should be ush with the top of the receiver and
the two thumb screws should be tightened before engaging the ITA. See Figure A.
•For VXI type receivers (Part # 310104127, 310104194, 310104248, 310104299, 310104307,
& 310104279) — the two securing screws located near the top of the receiver (one on
each side), must be tightened prior to ITA engagement (Figure B).
•The handle may now be rotated to the lowered position.
•The ITA, upon being inspected, is now ready for engagement with the receiver. The
receiver should be checked one last time for any foreign objects that may hinder
the engagement. The top rollers of the ITA may then be placed onto the receiver’s
built-in “hangers” with the handle in the lowered position. The ITA may be engaged
with the receiver only if properly lined up - meaning that the ITA must be placed
onto the receiver in the upright position. Care should be taken to have the top/side
notch of the ITA align for “mating” with the keying tab on the top of the receiver.
•Due to additional equipment being added onto the ITA, the user may nd that the
ITA and receiver will not line up as described above. One reason may be that the
additional weight on the ITA will cause it to pull away from the receiver at the top.
The user should apply pressure to the top of the ITA to counter the weight that is
pulling the top of the ITA away from the receiver (with the receiver handle in the
“open” position). The user may then carefully engage the system by raising the
handle until the handle makes contact with the receiver.
IN THE EVENT OF COMPLICATIONS, SUCH AS IMPROPER ALIGNMENT OF MODULES OR THE ITA, A TRAINED
TECHNICIAN SHOULD BE NOTIFIED IMMEDIATELY TO AVOID ANY DAMAGE TO THE SYSTEM. THIS SHOULD ALSO APPLY
TO ANY DIFFICULTIES THAT MAY BE EXPERIENCED DURING ENGAGEMENT.
CAUTION: WHEN ENGAGING THE ITA WITH THE RECEIVER, CAUTION MUST BE TAKEN TO ENSURE THAT THE ITA
IS PARALLEL WITH THE RECEIVER UPON ENGAGEMENT AND THAT THE ITA ROLLERS ARE ENGAGED AT THE SAME
TIME!
ALL POWER SUPPLIES FOR THE SYSTEM SHOULD BE PROPERLY DISCONNECTED PRIOR TO HANDLING. CAUTION
SHOULD ALWAYS BE USED WHEN ENGAGING, MAKING SURE THAT ALL FOREIGN OBJECTS ARE REMOVED
FROM THE SYSTEM.

Procedure For Checking ITA Squareness When Unit Has Been Damaged or Dropped
(Use procedure 1 or 2)
PARTS REQUIRED
ITA Frame being checked
Precision Square (preferably 18”)
Feeler Gage
PROCEDURE 1
(using a Surface Plate) —
1. Place ITA onto a Surface Plate with the ITA Frame’s
top on the Surface Plate and contact side facing
you as illustrated in Figure A.
2. Slide Precision Square up to left side (P1) of ITA.
3. Place Feeler Gage at point A and B (Figure A).
4. The difference between point A and point B
equals the squaring. This should be done upon
receipt of the ITA from the VPC factory and
recorded for referencing when the ITA is subject to
an out of squareness condition.
PROCEDURE 2
(for checking alignment in the eld) —
1. Place the side of the Precision Square on
the top left (P1) of the ITA with contact side
facing you as in Figure B.
2. Place Feeler Gage at point C and D (Figure B).
3. The difference between point C and point D
equals the squaring. This should be done upon
receipt of the ITA from the VPC factory and
recorded for referencing when the ITA is subject to
an out of squareness condition.
CARE AND MAINTENANCE
Figure A.
Figure B.
Serious damage can be caused due to mishandling or dropping the ITA or any system parts. The 90 Series and VXI Interface
System have been designed to be maintenance free, yet care does need to be taken when handling the ITA.
Upon receiving Interchangeable Test Adapters from VPC, it is recommended that ITA squareness is noted using the steps
below to verify future squareness (such as after being mishandled or dropped).

MICRO-SWITCH REMOVAL & INSTALLATION
A Microswitch is used in the 90 Series/VXI receivers to determine the presence (or absence) of an ITA engaged in the system. It is usually
congured so that power to the interface is turned off when there is no ITA present. An integrated Microswitch is standard on the 25 and 50
module receivers and available as an option for the 3, 6 and 10 Module receivers.
The 90 Series and VXI Interface Systems have been designed to be maintenance free; however, in the unlikely event that the Microswitch
needs to be replaced, please use the following VPC part numbers to order a replacement Microswitch: Part # 310 113 200 for 25 and 50
module receivers; and Part # 310 113 180 for 3, 6 and 10 module receivers. For removal/installation of the Microswitch, please read the
following steps.
For 25 and 50 Module Receivers:
1. Disengage the ITA from the receiver (remove the ITA completely).
2. With the receiver handle still in the open position (handle is down), unscrew the two plate retaining screws (using a Phillips screwdriver)
that are located immediately below the top right engaging mechanism/slot - this will expose the Microswitch.
3. Remove the necessary modules so that the Microswitch retaining screws may be accessed.
4. Unscrew the retaining screws (using a Phillips screwdriver), removing each as they are loosened (caution should be used so that the
screw(s) do not fall into the system).
5. Carefully remove the Microswitch for continuity testing.
For Microswitch installation, repeat steps 1 - 5 in reverse order.
For 3, 6 and 10 Module Receivers:
1. There are four slots machined into the receiver beside the two engagement slides that accept the ITA rollers. Locate the large slot
along the top of the right engagement slide (Figure 1).
2. Place the Microswitch in the slot, feeding the wires through the hole provided (Figure A).
3. Attach the Microswitch using the two screws provided. The mounting holes are located in the side of the receiver. One can be
accessed with the handle in the open position, and the other with the handle in the closed position.
4. Wire the Microswitch as desired.
AS WITH ALL ELECTRICAL SYSTEMS - DISCONNECT
ALL ELECTRICAL SUPPLIES TO THE SYSTEM PRIOR TO
REMOVAL OF MICROSWITCH.

Painting:
1. Modify cover plates as needed.
2. Using tape or another masking material, cover the areas on
the enclosure not to be painted as indicated by the drawing
below to ensure panel-frame conduction.
3. Paint Housing and Cover plates (Exterior surfaces only).
Hardware and Gasketing:
4. Remove masking material.
5. To mount each handle to the cover plates, seat each end
into a guide ferrule, then attach the handle to the outside
face of the cover using two 10-32 x 3/8 mounting screws,
two lock washers, and two at washers.
6. Insert one 1/4-turn fastener at a time through the front of
a cover plate. Lay cover plate face-down with 1/4-turn
fastener sticking up. Slide retaining washer over the fastener
such that the outer area of the washer is furthest away from
the cover plate (like a soup-bowl with a hole in the middle
of it). Slide a tube (.375 dia. with .220 inside dia.) over the
retaining washer and strike rmly with a mallet with cover
plate on a solid surface. Ensure that the fastener is retained
by washer. Repeat for all fasteners on each cover plate.
7. Working on a at surface, apply a thin layer of adhesive to
a single gasket. Smooth with a putty knife or razor blade
so that there is a very thin, even layer (.003 - .005, or paper
thickness) on the gasket. Make sure the adhesive covers out
to all edges. (Avoid allowing build-up of excess adhesive in
the gasket holes).
8. Immediately afx the gasket to the housing, rst aligning the
inside of the gasket with the inside edge of the enclosure
opening. Check for proper alignment of the gasket and
housing holes and adjust as necessary. Once all holes are
aligned, immediately attach the cover plate and lock down
for at least 20 minutes to allow the adhesive to properly set.
9. Repeat steps 7 & 8 for each cover.

TROUBLESHOOTING
ITA Engagement Bearings/Studs are not lining up with the Engagement Slots of the receiver
• Check the alignment of the ITA Frame. There is a possibility that the ITA Frame will have misaligned itself if it is dropped (See Procedure
for Checking ITA Squareness on page 4, Section 3). Contact Virginia Panel Corporation - user adjustments to System, unless authorized,
will void the warranty.
• Forceful engagement of the receiver and the ITA will result in serious damage to multiple parts of the system (modules, receiver, ITA
and Contacts)!
ITA Frame is not lined up when in the process of engagement with the receiver
• With a typical contact load, approximately 35lbs force is needed to engage the handle. Consult with a VPC application engineer for
detailed contact loading information.
• If excessive force is required, this may indicate that the ITA out of alignment or that a Module is not mating with its intended Module.
Remove and inspect the ITA for alignment (See Procedure for Checking ITA Squareness on page 4, Section 3). Contact Virginia Panel
Corporation - user adjustments to System, unless authorized, will void the warranty.
• Check for foreign objects/tools.
• Verify the orientation of the receiver and ITA modules (See Section 2).
• Inspect the matching of modules - Power ITA Module to mate with Power receiver Module, etc. (See Section 2).
• Forceful engagement of the receiver and the ITA will result in serious damage to multiple parts of the system (modules,
receiver, ITA and Contacts)!
Excessive force is needed upon engaging the Handle
• This may indicate that the ITA was dropped and is out of alignment or that a Module is not mating with its intended Module. Remove
and inspect the ITA for alignment (See Procedure for Checking ITA Squareness on page 4, Section 3). Contact Virginia Panel
Corporation - user adjustments to system, unless authorized, will void the warranty.
• Check for foreign objects/tools.
• A damaged Contact(s) may provide enough resistance to notice. Upon replacing a Contact on the ITA, the mating Contact on the
receiver side should also be inspected and replaced if necessary (See Section 2).
• Verify the orientation of the receiver and ITA modules (See Section 2).
• Inspect the matching modules - Power ITA Module to mate with Power receiver Module, etc. (See Section 2).
• Forceful engagement of the receiver and the ITA will result in serious damage to multiple parts of the system (modules, receiver, ITA
and Contacts)!
ITA will not engage with the receiver after diagnosing the above problems
• Contact Virginia Panel Corporation - user adjustments to the System, unless authorized, will void the warranty.
No continuity upon engagement
• Upon replacing a Contact on the ITA, the mating Contact on the receiver side should also be inspected and replace if necessary (See
Section 2).
• Check wiring - replace if necessary.
• Contact not secured in module.
• 50 OHM ITA contact engaged with 95 OHM receiver contact will damage the 95 OHM contact.
• 95 OHM ITA contact engaged with 50 OHM receiver contact will not make continuity/contact.
A “short” in the wiring upon engagement
• A damaged Contact(s) may provide enough resistance to notice. Upon replacing a Contact on the ITA, the mating Contact on the
receiver side should also be inspected and replaced if necessary (See Section 2).

PRECAUTIONARY NOTES
The following is a listing of precautionary notes found within this Manual and otherwise. They should be noted and followed for the
equipment to operate at an optimum state.
• Never probe a contact without using a mating patchcord as a test lead.
•Never forcefully engage a system if there is an excessive amount of resistance on the handle.
•Never allow an ITA to drop as this may cause misaligned engagement and/or irreparable damage.
•Always insert and extract a contact insertion/extraction tool inline with the contact. Never apply pressure to the side as this may break
either contact or tool. This also applies to forming and enlarging tools.
•When engaging the ITA with the receiver, caution must be taken to ensure that the ITA is parallel with the receiver upon engagement
and that the ITA rollers are engaged at the same time!
•It is advisable that power to the Interface System be disconnected prior to handling and maintenance.
•Caution should always be used when engaging, making sure that all foreign objects are removed from the system.
• 50 OHM ITA contact engaged with 95 OHM receiver contact will damage the 95 OHM contact.
•Use care when hinging receiver down. Always maintain hand contact to prevent receiver from dropping suddenly, resulting in
damage to the system.
