21 PULL-THRU USER S MANUAL: SECTION 5 MICRO-SWITCH REMOVAL AND INSTALLATION A microswitch is used to determine the presence (or absence) of an ITA engaged in the system. It is usually configured so that power to the interface is turned off when there is no ITA present. TOOLS REQUIRED Phillips Screwdriver FOR MICROSWITCH PART # : 1. Disengage the ITA from the receiver (remove the ITA completely). 2. With the receiver handle in the closed position (handle is down), 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). 3. Carefully remove the Microswitch for continuity testing. For Microswitch installation, repeat steps 1-3 in reverse order. AS WITH ALL ELECTRICAL SYSTEMS - DISCONNECT ALL ELECTRICAL SUPPLIES TO THE SYSTEM PRIOR TO REMOVAL OF MICROSWITCH. 5-1 For the most current information available, visit

22 PULL-THRU USER S MANUAL: SECTION 6 ITA & RECEIVER ENGAGEMENT Prior to engaging an ITA with the receiver for the first time, ensure all modules (ITA and receiver) are properly installed. This involves inspection of modules to ensure proper mounting and to verify module positioning. Module positions are shown in Figures A and B. Modules must be installed such that Pin 1 of each respective mating receiver and ITA module pair are adjacent. VPC recommends that Pin 1 always be positioned to the left in the receiver and ITA frames. All ITA Modules must match the respective receiver Modules. It is crucial for all modules to be installed properly. MODULE POSITION 1 MODULE POSITION 2 MODULE POSITION 3 MODULE POSITION 4 MODULE POSITION 5 MODULE POSITION 6 MODULE POSITION 7 MODULE POSITION 8 MODULE POSITION 9 MODULE POSITION 10 MODULE POSITION 11 MODULE POSITION 12 MODULE POSITION 13 MODULE POSITION 14 MODULE POSITION 15 MODULE POSITION 16 MODULE POSITION 17 MODULE POSITION 18 MODULE POSITION 19 MODULE POSITION 20 MODULE POSITION 1 MODULE POSITION 2 MODULE POSITION 3 MODULE POSITION 4 MODULE POSITION 5 MODULE POSITION 6 MODULE POSITION 7 MODULE POSITION 8 MODULE POSITION 9 MODULE POSITION 10 MODULE POSITION 11 MODULE POSITION 12 MODULE POSITION 13 MODULE POSITION 14 MODULE POSITION 15 MODULE POSITION 16 MODULE POSITION 17 MODULE POSITION 18 MODULE POSITION 19 MODULE POSITION 20 Figure A. G20 receiver shown from the mating side; G20 ITA shown from the wiring side. 1. The receiver should be checked for any foreign objects that may interfere with engagement. 2. After inspection, the ITA is ready for engagement with the receiver. The ITA may be placed onto the receiver platform and properly positioned relative to the receiver guide pins. Ensure that the ITA roller bearings are aligned with the receiver slide openings when the receiver handle is in the open position. 3. Carefully rotate the handle forward to actuate the receiver slide engagement mechanisms, which will draw the ITA into engagement position with the receiver. Once the handle reaches a positive stop at the end of its travel and latches into place, the modules are engaged. 4. Upon completing use of the ITA, rotate the receiver handle to the open position, remove the ITA, reinstall the receiver protective cover and rotate the handle to the closed position. 5. Always protect the contacts when the system is not in use. The receiver contacts are protected when either the ITA or receiver protective cover is engaged. VPC recommends use of both receiver and ITA protective covers to avoid potential contact damage. IMPROPER INSTALLATION WILL DAMAGE THE MODULES, AND POSSIBLY THE ITA AND/OR RECEIVER. IN THE EVENT OF COMPLICATIONS, A TRAINED TECHNICIAN SHOULD BE NOTIFIED IMMEDIATELY TO AVOID ANY DAMAGE TO THE SYSTEM. THIS APPLIES TO ANY DIFFICULTIES THAT MAY BE EXPERIENCED DURING ENGAGEMENT. 6-1 For the most current information available, visit

23 PULL-THRU USER S MANUAL: SECTION 7 TROUBLESHOOTING ITA Frame is not lined up when in the process of engagement with receiver This may indicate that the ITA is out of alignment or that a module is not mating with its intended Module. Remove and inspect the ITA for alignment Check for foreign objects/tools. Inspect the matching of modules -power ITA module to mate with power receiver module, etc. Excessive force is needed to engage the Handle 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 is out of alignment or that a module is not mating with its intended module. Remove and inspect the ITA for alignment. Contact Virginia Panel Corporation unauthorized user adjustments to system will void the warranty. Check for foreign objects/tools. Contact damage may provide enough resistance to notice. Upon replacing a contact in the ITA, the mating contact on the receiver side should also be inspected and replaced if necessary. Verify the orientation of the receiver and ITA modules. Inspect the matching modules - power ITA module to mate with power receiver module, etc. ITA will not engage with the receiver after diagnosing the above problems Contact Virginia Panel Corporation unauthorized user adjustments to the System will void the warranty. No continuity upon engagement When replacing an ITA contact, the mating contact on the receiver side should also be inspected and replaced if necessary. Check wiring and replace if necessary. Contact not secured in module. A contact may be damaged. Visually check all contacts for damage to potentially isolate damaged pin prior to checking for continuity with a multi-meter. A short in the wiring upon engagement A damaged contact(s) may cause high resistance. Upon replacing a contact in the ITA, the mating contact on the receiver side should also be inspected and replaced if necessary. Check wiring and replace if necessary. Receiver and ITA will not disengage This may indicate that the engagement mechanism within the receiver is faulty -contact Virginia Panel Corporation immediately- 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)! 7-1 For the most current information available, visit

24 PULL-THRU USER S MANUAL: SECTION 8 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 in line 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. 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. The foremost precautionary step that needs to be taken is to protect the interface system from damage caused by people (bumping into the receiver/ita assembly with a box, chair or electronic equipment for example). To prevent this, VPC recommends engaging either the ITA or the receiver Protective Cover to the receiver when not in use. 8-1 For the most current information available, visit
