1.1 Requirements

NOTE

Required Documents

During maintenance on the product, the work steps in the
certificate must be documented accordingly.

Maintenance is divided into chapters (as a rule, max. 6 hours
for components). Since there can be the same component
more than one in a customer system, the component check­points in the certificate are listed accordingly. Each compo­nent must then be entered with the Part Number and Serial
Number. There are also "options" in the customer system.
The options must be check marked accordingly in the certif­icate.

With parts that must be replaced periodically (battery/steel
cables...), the startup date or the last replacement date must
be entered to ensure the ability to track the dates. As a rule,
the date can be found in the User Handbook (Handover Pro­tocol / old Maintenance Certificate).

• Maintenance Protocol

• See also the individual chapters.

1. Are any metal shavings or slivers of the steel cable visible on the spring-loaded mecha­nism or inside the cover panels? (1/Fig. 13 / p. 22)

2. Are the cable grooves in the spring-loaded mechanism (2/Fig. 13 / p. 22) in good
order?

They are then okay.

a) If no aluminum shavings are seen on the steel cable reel. (A situation such as the

one shown in (1/Fig. 13 / p. 22) is not okay!)

b) If the steel cable grooves are flat and smooth. They may not be worn or abraded to

the point where they are uneven. A situation as shown in the illustration

(2/Fig. 13 / p. 22) is not okay!

c) If only a light, powdery deposit (3/Fig. 13 / p. 22) is visible.

- If the condition of the spring-loaded mechanism is as poor as that shown in

(Fig. 13 / p. 22), then the spring-loaded mechanism together with the steel

cables must be replaced.

3. Is the safety cable long enough? (Measure the deflection of the safety cable.)

a) Move the telescope into the highest position.
b) Deflect the safety cable upward, as shown in (Fig. 14 / p. 23), until great mechani-

cal resistance is felt. Measure deflection A (distance between the support cable and
the safety cable) at the location indicated (30 mm from the edge of the casting).

NOTICE

Deflection A must be 55 mm or more.

¹ If the deflection is less than 55 mm, but can still be

clearly felt, the system can remain in operation. Both
cables will need to be replaced as soon as possible.

¹ If the safety cable cannot be deflected (safety cable is

under load!), then the system must not be operated any
longer and both cables must be replaced.

Fig. 15: Safety cable

NOTE

Beginning approx. January 2008, new stands / spring-loaded
mechanisms with plastic-coated support cables will be
shipped. The steel safety cables will still have no coating.

With support and safety cables not plastic-coated:

• Check the steel support and safety cables for splits.

- To do this, run a cloth over the cables as shown in (Fig. 15 / p. 24). Splits and cable
damage are evidenced by the fibers caught. To do this, move the telescope into both
end positions. With the telescope moved in, in particular check both the support cable
and the safety cable where they run into the spring-loaded mechanism.

• Relubricate the cables with VISCOGEN KL300.

NOTE

With plastic-coated support cables:

If splits are found, both cables must always be replaced.

• Perform a visual check of the plastic coating on the support cable along the entire cable

length that is accessible. To do this, move the telescope into both end positions. With
the telescope moved in, in particular check both the support cable and the safety cable
where they run into the spring-loaded mechanism.

- There may be no cracks or deep scratches in the plastic coating.

• Clean the cable notches in the spring-loaded mechanism of wear residue.

• Plastic-coated support cables may not be lubricated.

PMA Checking the Support Arm / Rotation Movements

1

Fig. 16: Rotation movements

• Rotation around the horizontal axis (1/Fig. 16 / p. 25).

- Checking the Movement and Stop Functions

• Check movement and the stop function around the vertical axis (Fig. 17 / p. 25).

• Check whether rattling or other unusual noises can be heard during movement around

the vertical axis (Fig. 17 / p. 25). If needed, lubricate the bearing at (1/Fig. 17 / p. 25):

- To do this, release the tension on the bearing lever (2/Fig. 17 / p. 25), i.e. press the
spring (3/Fig. 17 / p. 25) together with pliers or a vice grip.

- Remove the countersunk screw (1/Fig. 17 / p. 25), take out the eccentric shaft with
bearing.

- Remove the bearing from the eccentric shaft and lubricate both parts with Optimol
Longtime PD2.

- Insert the bearing and eccentric shaft and thread in the countersunk screw

(1/Fig. 17 / p. 25); when doing this, use Loctite 221. However, do not tighten the

countersunk screw (1/Fig. 17 / p. 25) completely.

• Following installation of the bearing, the eccentric shaft must be readjusted; to do this:

- Adjust the eccentric shaft at (1/Fig. 17 / p. 25) accordingly using a 17 mm open-end
wrench; to do this, release the brake at the control panel.

- Following successful adjustment, secure the eccentric shaft in this position by tight­ening the countersunk screw (1/Fig. 17 / p. 25).

- Move into the position several times from both directions and check the result of the
adjustment.

- If needed, repeat the adjustment.

30 Final Work Steps

NOTE

To record the maintenance steps and in particular the ground
wire measurement, the certificate

XP00-000.835.02 or “XP00-RFU.835.01” (simplified version)
must also be filled out.

According to IEC 62353, the measured values must be com­pared to the old values. The old values can be seen in the

* Startup Certificate

* old Maintenance Certificate

* old certificate for the checks per IEC 62353 XP00-000.835.02
or “XP00-RFU.835.01”.

If significant differences are found or if the measured values
exceed 180 mOhm, it may be necessary to initiate corrective
measures.

As a rule, the ground wires are not connected or not cor­rectly connected.

• Test procedure:

- Measure between all conductible parts of the system that can be touched and the
ground wire bus rail (e.g. in the generator, power distributor).

If using direct current, repeat the measurement with the opposite voltage polarity.
Both measured resistance values may not exceed the permissible value.

The measurement values between the generator “ground wire bus rail” and the
installed guide rails, i.e., large mechanical parts of the components, must be
recorded.

Measurement values on "paneling screws", etc. are reproducible only with difficulty.

¹ Maximum value: 0,2 Ω (Observe country-specific regulations!)

Exception: Accessory rails on the collimator and tabletop.

NOTE

Exceptions:

Accessory rails on the collimator and tabletop.

Components with Voltage less than/equal to 24 Volts

Covers, which cover electrical components with voltages
lower than/equal to 24 V.

NOTE

For customers without a service contract, a label "Next main­tenance, MM.YY" can be placed close to the operating loca­tion.
