SITEMA KRGP Series, Operating Manual

The Safety Lock has the advantage that it does not release 

under load

.

The Safety Lock can normally be released in this case only if release pres-
sure is applied and the load is simultaneously lifted, i.e. if the load has al-
ready been transferred safely elsewhere. To ensure this 

safety advantage

,

the 

load

 must have a 

minimum value

 during operation. See minimum

value F6 in “Technical data sheet TI-S12”.

WARNING

Danger in case of misuse!

Misuse of the Safety Lock can lead to dangerous situations.

Ü

Use the Safety Lock only to hold loads that do not exceed the admissi-
ble load. The static weight acting on the rod must never exceed the ad-
missible load.

Ü

Use the Safety Lock only in explosion-proof areas.

Ü

Use the Safety Lock only for securing static loads, not for braking dy-
namic loads.

Ü

Do not use the Safety Lock as a positioning device.

Ü

Always leave the rod inserted during operation.

Ü

Leave the Safety Lock assembled. Do not open the Safety Lock.

Ü

Maintain the Safety Lock in its delivered condition. Do not manipulate
the Safety Lock.

2.2   Regular performance testing

Regular performance testing ensures safe functioning of the Safety Lock.
Use the performance test to verify safe functioning of the Safety Lock also
after unforeseen events occur.

A performance test must be carried out in the following cases:

• after installation

• after any use at variance from the intended use

In safety applications, the functioning of the Safety Lock must be checked 

at

least every 6 months

. Much more frequent testing may also be required de-

pending on the application parameters (degree of contamination, cycle fre-
quency, control system). In some cases even daily fully automated testing is
necessary. This detects any trouble at an early stage.

If the test finds that the Safety Lock no longer conforms to the specified prop-
erties, the stipulated safety for working on plant and other machinery is no
longer assured. The Safety Lock must be returned to SITEMA without delay
for professional servicing and acceptance testing.
