Introduction 2. INTRODUCTION The Ansaldo STS USA, Inc. (ASTS USA) TransPortal™ 1 Interlock Monitor (TIM) is a comprehensive status monitoring and reporting device capable of remotely monitoring the ASTS USA MICROLOK®2 II controller (MLK). The TIM is typically installed at field locations where timely on-site access to the MLK is a concern. This document contains information for the installation, setup, and use of a TIM.
Introduction locations is not practical, the TIM may be used to monitor the MLK remotely and provide notification of these MLK events. This minimizes the need for travel to very remote sites. The TIM connects to the MLK using a serial interface. The TIM also connects to an SNMP host to deliver the events detected within the MLK. When connected, the TIM continuously polls the MLK for its current log file and examines the file for new, reportable events.
Introduction 2.3. Electrical and Mechanical Specifications The TIM meets all applicable environmental, EMI, and vibration tolerance specifications for Class C equipment. Table 2-1 and Table 2-2 list the TIM specifications. Table 2-1. Operating Specifications PARAMETER VALUE System Power Source Voltages Temperature Range Humidity Vibration EMI Isolation and Protection Table 2-2. 8 to 30VDC, 10W –40 to +70°C 0% to 95% non-condensing per AREMA 11.15.1 Per AREMA 11.15.1 Per AREMA 11.15.1 Per AREMA 11.3.
Introduction Capable of communicating over any type of public or private, wireless or wireless IP-based WAN, the TIM transmits SNMP-based Trap/Inform messages when any alarm situation is confirmed, and delivers periodic operating information and health check messages. SNMPbased TIM devices are configured to deliver SNMP Trap/Inform encoded alarm and status messages to properly configured SNMP host applications.
Introduction 2.5.4. Power Input The TIM is powered by 8–30VDC. Although the power input is fully isolated and protected against reverse battery connection, observe the polarity when connecting power to avoid damage to the unit. 2.6. Top Panel Keypad/Displays Due to the persisted IP network connection that the unit maintains, all monitored status, alarm information, and configuration settings can be managed over the network (Remote Operation).
Introduction 2.6.2.4. System Status The System Status LED summarizes the health of the unit's internal operation. It is typically green, indicating that all systems are functioning nominally. If the System Status indicator turns red, it is a sign that one or more of the following conditions has been detected: • • • A corrupted or erroneous property file or internal error log entry. An application bundle is not properly running or has not started.
Installation and Setup 3. INSTALLATION AND SETUP This section provides detailed instructions for the proper installation and setup of the TransPortal Interface Monitor (TIM). Included are steps to perform the following: 1. 2. 3. 4. 5. Gather the tools and devices needed for installation. Unpack and inspect the TIM. Mount the TIM. Connect the field wiring. Connect the power source and power up the unit for the first time.
Installation and Setup 3.3. Physical Mounting The TIM may be mounted horizontally on a shelf or vertically on a wall. Select a panel, wall, plywood back plane, or shelf in a location where it will not be exposed to harsh weather extremes or moisture. If possible, the unit should be mounted at a height to allow easy access to the display, controls, and I/O connections. It is recommended that the unit be installed at least 18-inches away from high-voltage power sources or other equipment.

Configuring the Transportal Interlock Monitor 4.3.3. SNMP Trap Timestamp File To prevent the resending of traps/informs upon a system restart, a timestamp of the last trap/inform is stored locally on the unit. The “/home/microlok/snmp.trap.timestamp” file contains this timestamp. When the software starts, this timestamp is read and used to prevent any previously generated traps from being sent to the SNMP manager. The timestamp is updated each time a new trap or inform is sent. Figure 4-14. Typical snmp.

Support and Maintenance 5. SUPPORT AND MAINTENANCE There are no user serviceable parts or components in the TransPortal Interlock Monitor (TIM). The unit is shipped with an internal lithium battery enabled, supporting the unit's real time clock. While the battery-backed clock provides for faster unit startup, it is entirely optional for proper operation because the TIM has several means of obtaining the proper date and time for operation (i.e., over the network and using GPS, if so equipped).
