Installation 3. SECTION 3 – INSTALLATION 3.1. GENERAL This section contains general installation procedures for Type B relays. Included is a procedure for inspecting each relay prior to installation, followed by the installation and adjustment procedure. 3.2. RELAY INSTALLATION TOOLS AND SUPPLIES See Appendix C for a summary of B relay tools. See Section 7 for a listing of installation plugboards and supplies. 3.3. INSPECTION Upon receipt of a shipment of Type B relays, inspect them for cleanliness and overall condition. Also, always verify the operating characteristics of the relay before installing it in a particular circuit. Prior to installing a Type B relay, follow the inspection procedure provided in Table 3–1. Refer to section 2, Figure 2–1 for an illustration identifying the basic B relay components. Table 3–1. B Relay Pre-Installation Inspection Procedure Step Procedure 1 Check that the relay cover and seal are not damaged. WARNING BREAKING THE RELAY COVER SEAL VOIDS THE WARRANTY ON THE RELAY. 2 Verify that the relay prong surfaces are clean and not bent. While the prongs of the relay that engage with the terminals in the plugboard are clean and adjusted when they leave the factory, there is always the chance that they may become dirty or bent in handling. If prongs are dirty, clean by burnishing. 3 When relay racks complete with plugboards are received, verify they are clean and not broken or cracked. The terminals should lie close to the insulators. The guide rods should be straight and at right angles to the plugboard. P1457, Rev. Nov/07 3–1 Alstom Signaling Inc.
