...

• Antenna and antenna cable are supplied separately.

• Mount the antenna external to the building

• Never mount antenna inside an equipment enclosure or building

• The antenna must be placed a minimum of 3 meters from sensitive electronic signalling equipment such as SSI.

• The antenna features a magnetic mounting base. If this is not suitable, contact MPEC to discuss alternate mounting arrangements.

• The antenna is to be mounted upright, with the “whip” element pointing skyward.

• Ideally the antenna shall be placed clear of large structures and earthworks.

• Bear in mind during placement that the antenna may need relocating during commissioning if inadequate signal strength is available.

• A minimum12 mm circular aperture is required to route the antenna cable into the building / enclosure.

• If the building or enclosure structure must be pierced to run the antenna cable, ensure this is done in a responsible manner using appropriate tools. Any new openings must be appropriately sealed against moisture ingress and rodent attack.

• route the antenna cable using appropriate cable management from antenna to SLX device.

• Avoid sharp radius bends and never bend the antenna cable tighter than a 13mm radius.

• Avoid running the antenna cable directly parallel and close to sensitive digital signal cables, such as SSI data links.

• Do not attempt to shorten or lengthen the cable unless competent to do so and in possession of the appropriate tools and connectors.

• MPEC offer a range of antenna cable lengths, so please contact MPEC if the standard 5m cable is inappropriate.

• Hand tighten the hexagonal SMA connector to terminal W1 of the S-LX compute module. Do not use tools to over-tighten.

• Hand tighten the round TNC connector to the antenna base. Do not use tools to over-tighten.

Connect AC Power Supply

General

• The HZS PSU and Port Isolator plug connector features six terminals:

  • 2 x BX terminals. The terminals are electrically common and accept the “live” connection to the incoming AC power supply.

  • 2 x NX terminals. The terminals are electrically common and accept the “neutral” connection to the incoming AC power supply.

  • 2 x E terminals. The terminals are electrically common and provide a protective earth connection to the incoming AC power supply.

  • The electrically common terminals allow power circuits to be daisy-chained to multiple S-LX systems whilst only occupying a single primary busbar connection.

• Each terminal features a spring-cage contact to prevent accidental contact with hazardous live voltage. Guidelines for successful and safe connection are as follows

  • Maximum conductor area of cable should be 1.5 mm square

  • Cables shall always be fitted with ferrule crimps of the appropriate size.

  • Ferrule crimps shall be fitted using a “square end crimper”, such as WEIDMULLER PZ 10 SQR WIRE END FERULE CRIMPER. P/N: 1445080000

  • A tool is required to release the spring inside the connector to allow cable insertion

    • Straight 2.5 mm flat bladed screwdriver

    • Angled flat bladed screwdriver - https://www.wago.com/gb/tools/operating-tool/p/210-658

  • When fully inserted, no exposed conductor or ferrule should be visible to prevent electrical shorting and shock risk

Connection to BX110 Isolated Signalling Supply

• The HZS device is product approved by Network Rail for connection to all 110 V AC isolated power circuits.

• BX terminal shall be connected to a fused position on a BX110 busbar

• The primary fuse shall be of 3 Amps - Slow Blow (3TA)

• NX terminal shall be connected to a vacant position on a NX110 busbar

• E terminal does not require terminating as a protective earth bond is not required, however, safety and performance is not compromised if the earth terminal is connected.

Connection to 230 V AC Domestic Supply

• The HZS device has been safety tested for connection to 230 V AC domestic mains supplies

• The HZS device remains isolated from earth unless under fault condition.

• The BX terminal shall be connected to an appropriate “live” AC connection.

• The primary fuse shall be of 3 Amps.

• The NX terminal shall be connected to an appropriate “neutral” AC connection.

• The E terminal must be connected to a suitable protective earth connection. This is required to provide electric shock protection under fault condition.

• Protective Earth connection cable shall be of 1.5 mm square CSA.

Connect Serial, Ethernet or USB Connection

• Connections to monitored signalling equipment are made through serial, Ethernet or USB ports

• Refer to the example “overlay diagrams” which detail connection of the monitoring ports.

• VHLC Level Crossing Applications

• HXP3 Track Circuit Applications

• Westronic S2 TDM Applications

• Westronic 1024 TDM Applications

• SSI Technicians Terminal Applications

• AZLM Axle Counter Applications

• MCS Applications
