  • 10 General1.3 System Maintenance Planning

    1.3.1 Partial MaintenancePartial maintenance is performed every 6 months and grouped into 3 core packages:

    - Safety Inspections - Excerpt from Preventive Maintenance (Part 2) - Image Quality Check

    1.3.2 Full MaintenanceFull maintenance is performed every 12 months and includes partial maintenance as well. To improve planning and maintenance, the individual tasks have been grouped into 4 core packages as follows :

    - Safety Inspections according to EN 62353:2008- Preventive Maintenance (Part 1) - Preventive Maintenance (Part 2) - Image Quality Check

    Each of these 4 packages can be performed independently of the others and includes the complete instructions in the corresponding chapter. This makes it possible to schedule full maintenance over several days. The required work times will be extended in accordance with the corresponding Next steps.

    1.3.3 Spirit / Spirit Power and IES of Emotion: Preventive Parts ReplacementAPC 750VA UPS (P/N: 03806739 and 03806747) and MGE 1500VA UPS (P/N: 07733376 and 07733368) have to be replaced every 2 years beginning with the date of installation. The date for the next replacement has to be documented in the Maintenance Protocol. (Note: MGE 2200VA UPS (P/N: 07735090) and new HenDan 1500VA UPS (P/N: 10049948 and 10049944) are equipped with a long-lasting battery (5 years / 25 C). There-fore, preventive replacement of the UPS is not necessary.)

    1.3.4 Checking the drive belt tension

    NOTE The drive belt tension has to be measured during systeminstallation, each time maintenance is performed, and afterreplacement of the drive belt. Additional measurements areunnecessary. Emotion (2007) / Spirit CT02-025.831.02.13.02 Siemens, 200601.11 SSME CS

  • General 111.3.5 Checking the gantry brake

    NOTE A loose gantry brake may lead to safety-related risks, e.g.,during tube replacement. The gantry brake has to be checkedduring system installation and each time maintenance is per-formed on the system.

    Follow the steps below to check the gantry brake: Switch off the system and secure it against unintended switch on. Lock the gantry brake. With a reasonable force, carefully push the HV tank clockwise to check if the gantry disk

    rotates. If the disk rotates, the gantry brake has to be adjusted.

    Fig. 1: Drive belt tensionPos. 1 DistancePos. 2 Adjustment screw

    Measure the distance (1) between the washer and the edge of the cylin-der with a feeler gauge as shown.

    The distance must be between1.8 mm and 2.2 mm.

    If necessary, adjust the distance with the adjustment screw (2).

    If necessary, adjust the gantry brake as shown in the steps below:

    Unlock the brake (3) and loosen the brake shaft lock nut (1) until the brake cap (4) screw is moveable by hand. Note: the shaft lock nut (1) may look different depending on the system assembly.

    Turn the brake cap (4) away from the gantry belt to leave a small gap between the brake cap and the gan-try belt.

    Lock the brake (3), and screw in the brake cap (4) until the brake cap (4) touches the gantry belt.

    Unlock the brake and turn the brake cap (4) one more time clockwise toward the gantry belt to assure tight attachment.

    Fasten the brake shaft lock nut (1). Lock the brake to test the adjustment

    NOTEIf the new one is a Hendan UPS (Part number: 10049948 and 10049944), strictly follow the conditions below: To avoid tipping over during installation, first install the

    bracket (accessory) at the bottom of the UPS (rear) with two screws.

    Do NOT lay the UPS on top of the ICS and IRS. Otherwise, it will damage the computers.

    The UPS will be positioned between ICS and IRS (leave a space between them) in the IMS cabinet. For early ver-sions of the IMS cabinet with insufficient space (Spirit only), place the UPS in a safe location outside of the cab-inet.

    NOTEIf the new one is a Hendan UPS (Part number: 10049948 and 10049944), strictly follow the conditions below: To avoid tipping over during installation, first install the

    bracket (accessory) at the bottom of the UPS (rear) with two screws.

    Do NOT lay the UPS on top of the IES and other comput-ers. Otherwise, it will damage the computers.
