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

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.

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

adjuster and the connection joint is 1000 +/- 10 mm. Loosely
install a cable tie around the belt and position it approx. in the
center of the ten-

a spring scale (100 N) into the cable tie. Position a ruler or
measuring tape in the vertical position next to the cable tie. Pull
the spring scale in the vertical direction with a tension of 25 +/-
1 N and measure the
vertical change in distance (see below illustration). The
vertical change in distance must be 62+/-1 mm (at 25 +/- 1 N).

over during installation, first install the
bracket (accessory) at the bottom of the UPS (rear) with two

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.

forthe protective conductor. Ensure that the protective conduc-tor
cable is connected to this point when the system coversare
installed. The protective conductor cable is included withthe

All of the following "to" points should be accessible, protective
grounded metal parts of the CT component. Use a protective
conductor meter to perform the test and enter the data of that
measur-
ing device at the beginning of the protocol. Unroll the test
cable completely from the test device prior to performing the test
to
ensure correct results. Enter the value measured into the
corresponding protocol or checklist.
8.3.1 General notes when measuring at the monitorsAlways follow
the note shown below when measuring at one of the monitors.
NOTE Disconnect the monitor signal cable to the computer.
Other-wise, the graphics board will be destroyed.
