7 1. GENERAL INFORMATION 1.1. Introduction This service manual provides description and installation information for Ansaldo STS USA's Solid State Code (SSCT) replacement for the GRS/ALSTOM Type B Size 2 mechanical code transmitter. This replacement (Figure 1-1) provides a solid state option for customers with existing installations utilizing the GRS/ALSTOM mechanical code transmitter configuration. Model numbers are determined by the nominal code rate and operating voltage of the code transmitter as outlined in Table Description Since the SSCT is a functionally equivalent plug-in replacement for the GRS/ALSTOM Type B Size 2 mechanical code transmitter, the physical size and positioning of the contact fingers are identical to the GRS/ALSTOM Type B Size 2 transmitter. Available nominal code rates are 50, 75, 120, 180, 270, and 420 Codes Per Minute (CPM). The contacts are arranged as "break before make." Front Back Figure 1-1.

8 Different types of contacts are provided for various applications with broad classifications of low voltage and high voltage ratings. To ensure that units of different code rates or contact ratings are not interchanged, an indexing plate is used that matches a set of holes to a set of pins on the plug-in base. Thus, the fundamental specification of the replacement SSCT is determined by the preset pin holes. (See Figure 1-2 and Table 1-2 for the index patterns.) Unlike the mechanical counterpart, however, the high voltage version of the SSCT is relegated to only AC switching. The low voltage version will be suitable for either AC or DC switching Specifications Operating Range 8 to 16 VDC Reverse voltage protected. Indications Alternating LEDs Temperature Range -40 to + 70 C Switch Rating Low Voltage - AC or DC 2.5 amperes, 32 volts DC Max.* or 22 VRMS AC Max., 0.5 W ON resistance (Short circuit protected) Tranzorb transient protected at 34 volts peak. High Voltage amperes 150 VRMS Max.* AC only, The voltage drop is 1.25 volts across an ON switch and is independent of load current (an external 10-ampere fuse required for short circuit protection). MOV transient protected to 230 VRMS. Number of Switches 4 arranged in opposing pairs Dielectric Strength 2000 VRMS between all external isolated connections and case except across open switches which are limited by transorb or MOV protection. Current Draw 25 volts; volts; and volts. Maximum voltage is determined by a Tranzorb to protect DC switches from excessive voltage spikes when operating code following relays; for the AC version a 230 VRMS MOV is similarly used anticipating 120 VRMS as the source voltage.

13 2. INSTALLATION AND OPERATION 2.1. General WARNING To avoid personal injury or equipment damage, observe all electrical safety precautions when installing the SSCT Installation Procedure Refer to Figure 1-1 and Figure The SSCT is designed to replace the GRS/ALSTOM Type B Size 2 mechanical code transmitter. For high voltage switch short circuit protection, an external 10- amp fuse must be installed. 2. Ensure that the correct SSCT model is available for installation. Verify that the drilling of the index plate is correct for the code rate and model type (AC or DC). See Section 1.3 and Table 1-1 for code rates and power options and Figure 1-2 and Table 1-2 for index patterns. 3. Unscrew the two retaining nuts and remove the old code transmitter unit. Save the retaining nuts for securing the SSCT. 4. Install the SSCT into the existing base, replace the retaining nuts and tighten securely Verify Operation 1. Verify that the newly installed SSCT is operating by observing that the two LED indicators on the front of the unit are blinking in an alternating fashion. 2. Verify that the overall system, which the SSCT is a part of, is functioning properly Maintenance and Periodic Inspection 1. The SSCT is a maintenance-free unit. 2. There are no FRA requirements for periodic checking of solid state code transmitter units. Periodic verification of SSCT code rate operation is at the customer s discretion. 3. Malfunctioning SSCT units should be returned to STS USA for repair. Copyright 2019 SM 4568A Rev. 2, March
