1. INTRODUCTION
This manual details the correct method for installing the ZKL 3000 Remote Control (RC) Line
Blockage System safely. The ZKL 3000 RC system protects a section of track efficiently and effectively
by producing and monitoring a short circuit in the track, simulating a train in the section. This causes
the track circuit to be ‘OCCUPIED’, thus placing the protecting signals danger. This section is
immediately closed to rail traffic, enabling rail workers to perform work on the infrastructure safely.
The ZKL 3000 RC can be operated using either the Remote Switch (RS) 3000 or through the web
interface MTinfo 3000 .
2. DEFINITIONS & TECHNICAL SPECIFICATIONS
a. Application of ZKL 3000 RC
The ZKL 3000 RC can be applied in track types with a width of 1,435mm, such as:
• NP46
• UIC54
• UIC60
• 95 lb RBS
• 85 lb RBS
• 109 lb
• 110 lb
• 113 lb
Additionally, the ZKL 3000 RC can be used for mains voltage of both 1500 V and 25kV.
The ZKL 3000 RC can be used with the following track circuit systems:
• Jeumont-Schneider Peak Voltage track circuit section
• Classic track circuit: 12V alternating voltage 75 Hz
• Siemens electronic ripple control track circuits FTGS46 & FTGS917
• GRS Overlay Track Circuit (OTC)
• Alstom Jade system
• Bi-rail type CV50B3P
• High power pulses type CVTHBG
• TI21 type track circuits (EBI track 200)
• TI21-M type track circuits (EBI track 300)
• Aster SF 15 type track circuit
You must NOT use a ZKL 3000 RC in locations with any of the following:
• Level crossings and/or service roads (or alongside)
• Axle counters
• Switches and Points
