    The weight of the HD ALT (165Kg) is clearly marked and installers should ensure that they have sufficient measures in place to ensure a safe lift. The marked weight is for the HD ALT only and does not include any pallet or packaging weight.

  • Page 11: Description

    Once the signal head and post are inserted and the HD ALT is in its vertical position the two sub-assemblies are secured together using 8 x M24 bolts and this action forms the main mounting interface between the signal and the foundation.
  • Page 12 Loading and Performance’). This, together with the restrictions on signal head configurations included within the generic F001, F002, and F003 submission, delivers a robust system that mitigates the risk of the safe working load on the Signal Post and HD ALT Assembly being exceeded.
  • Page 13: Storage And Movement

    THE STORED ENERGY IN THE SPRING SYSTEM BEING RAPIDLY RELEASED The HD ALT is supplied on a large pallet as shown below and may be stored in the open air. The fasteners used to secure the unit to the pallet shall not be used as mounting hardware during installation and all packaging materials when removed, should be disposed of in accordance with local regulations.
  • Page 14: Tooling

    Tooling With the exception of the sighting scope, the only tools required to install a HD ALT onto a pre- prepared foundation are simple hand tools such as Torque Wrenches, 30mm and 36mm Sockets/Spanners. A RBK-221 key to remove the locking pin padlock will be required.
  • Page 15: Foundation And Site Checks

    Foundation and Site Checks Foundations should be secure and clear of any obstructions with studs fitted as shown in the Pre Installation Checks below. The laydown area for the signal shall not contain any obstacle or rising ground etc which would prevent the locking pin being inserted fully when the signal is reclined to its horizontal position A zone equivalent to the swept area of the signal being raised/lowered plus a reasonable margin either side to allow adequate footing for personnel engaged in the lift should be established.
  • Page 16: Pre Installation Checks

    Pre Installation Checks Prior to mounting the HD ALT a check shall be made with a spirit level to ensure that the foundation and therefore the top of all four mounting studs are level and at least 200mm of threaded stud is available above the foundation top. The mounting studs should be clean, free of damage and lubricated.
  • Page 17: Installation

    The signal and post should be checked for damage and any remaining transit packing materials should be removed and correctly disposed of. The HD ALT bore is to be free of debris or other obstruction and the Post Clamp should be loosened to enable the post to be inserted.
  • Page 18: Raising &Lowering The Hd Alt

    Using the lifting eyes highlighted in red shown in the image above, lift the HD ALT into position onto the four 24mm studs taking care to align the arrow marked on the Manufacturer Information Plate on the HD ALT baseplate parallel with the direction of the running rail. Then fit the remaining washers and nuts to secure it onto the studs Raising &Lowering the HD ALT...
  • Page 19: Inserting The Post And Erecting The Signal

    The bore of the HD ALT and the signal post should be checked for damage paying particular attention to the keyways on the post and the keys at the bottom of the HD ALT bore. Check the Plug Coupler and cable for damage, bent pins etc and any signs of moisture and then push them back into the bore of the post.
  • Page 20 Check that the post cannot rotate in the HD ALT bore and that the painted witness mark (indicated below) on the post is level with the top of the HD ALT. Do not fully tighten the locking collar until the signal is in the vertical position to allow for any settling.
  • Page 21 To raise the assembled signal and HD ALT, position an adequate number of workers around the sign and have them ‘take the strain’ to control any movement of the signal and remove the retaining pin from the base plate.
  • Page 22: Electrical Connection

    All mounting hardware should then be torque loaded to the values shown in the table in the Section “Torque Loadings”. Finally, hand tighten the HD ALT collar and secure with a padlock. Electrical Connection The infrastructure and signal cables are connected using standard plug couplers. To connect them, align the keyway and lug inside the connector shells then turn the locking collar by hand until an audible ‘click’...
  • Page 23: Signal Alignment

    Secure the cover with a padlock. The HD ALT should be bonded to earth if required by the use of bonding straps. No specific earth bonding arrangements to the signalling elements are required by virtue of the double insulated design, however a 17 mm through hole is provided on the base plate.
  • Page 24 Do not attempt to disassemble the scope to gain access to the internal lenses as this will disturb the optical alignment and the scope will need to be returned to Unipart Dorman for repair and recertification Heavy Duty Assisted Lift Trunnion Operation and Maintenance Manual Form Reference C64.65546...
  • Page 25 If a camera and bracket are to be fitted to the scope for recording purposes then please refer to the instruction leaflet, part number C65.65569 available on the Unipart Dorman Website. Heavy Duty Assisted Lift Trunnion Operation and Maintenance Manual Form Reference C64.65546...
  • Page 26 Using the alignment scope to provide visual cues, the signal is adjusted horizontally by rotating the base within the kidney slots and vertically by adjusting the angle of the HD ALT using the securing and adjustment nuts and the spherical washer sets shown in red.
  • Page 27 The spherical washer sets are specified as a mandatory feature in the Network Rail Product Acceptance and are essential for the tilt adjustment. Therefore, they shall not be omitted. When the signal is aligned correctly to the point on the signal sighting form and any photographic records etc are obtained, ensure all of the mounting nuts are correctly torque loaded as shown below and the alignment scope is removed and stored in its protective case.
  • Page 28: Post Installation Checks

    Post Installation Checks The Signal assembly has been designed for Plug and Play installation. Unipart Dorman recommends that the only test required is to have the signaller call on the aspects and ensure that the correct indications are displayed. This advice does not supersede any instructions issued by Network Rail.
  • Page 29 Withdraw the module sufficiently to access the inside of the signal head. If the signal is a four aspect variant, disconnect the plug coupler, which connects the two modules together. Remove and retain the cable clamps using a flat blade screwdriver Heavy Duty Assisted Lift Trunnion Operation and Maintenance Manual Form Reference C64.65546...
  • Page 30: Module Replacement (Other Signal Modules)

    It is then possible to remove the module completely. As the cable is withdrawn, the tracer cord and plug coupler will travel up the post and when it reaches inside the signal head can be undone and the module fully removed. Tie the tracer cord to the plug on the new module and use it to pull the new cable down the bore of the post, guiding the cable through the slot in the post and into the connection box.
  • Page 31: Additional Visors

    Additional Visors Unipart Dorman iLS signals are designed to be very resistant to sunlight effects such as washout or phantom, there may be however, a very small number of signals that directly face East/West that may suffer from the effects of low winter sun. To mitigate these effects Unipart Dorman has a range of extended visors available.

    1.5° if required. Fitting the wedge is covered in a separate document available from Unipart Dorman. These inserts should only be ordered and fitted after consulting with the Signal Sighting Chair responsible for that particular signal.
  • Page 35: Maintenance Activity

    Signal Husbandry If the HD ALT/Signal requires any cleaning activity to be carried out, the only medium approved is water with the addition of proprietary soap based detergents if required. Do not use any solvent based or abrasive cleaning material as this may irreparably damage the signal.
  • Page 36: Service And Repair

    Product Support Unipart Dorman has developed a comprehensive support package including product overview and awareness sessions for the HD ALT and its signal range and this can be arranged by contacting Unipart Dorman using the details on the back page.
