Not all component variants, which are possible according to this order
code, are available.
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefore
the compliance with the Machinery Directive is maintained.

2.2 Special versions

For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond
to the standard version.

2.3 Destination and use

The trapped key system, consisting of the components SHGV...,
SHGV/ESS... and SVM..., has been designed to prevent, in conjunction
with the control part of the machine, movable safety guards from being
opened before hazardous conditions have been eliminated.
By turning the key-operated selector switch from the trapped position
into the removable position, the NC contacts are positively opened and
the NO contacts closed.
This combination can only be used for applications, in
which the hazardous situation is eliminated without delay
(e.g. run-on movements) after the switch-off command
from the key-operated selector switch.
The trapped key system, consisting of the components SHGV...,
SVE... and SVM..., has been designed to prevent, in conjunction with
the control part of the machine, movable safety guards from being
opened before hazardous conditions have been eliminated. If the con-
trol part of the machine transmits a signal to the SVE... that the hazard-
ous situation has been eliminated, the key can be withdrawn from the
SVE..., as a result of which the movable safety guard can be opened.
If a delay device (e.g. timer) is used to by-pass the run-on
time, a failure of this device must not cause the delay time
to be reduced.
The user must evaluate and design the safety chain in accordance
with the relevant standards and on the required safety level.
Please implement the necessary organisational measures to
ensure that only one main key is in use for each system.
The user imperatively must ensure that a key number (coding)
is only used just once in every plant (factory premises).
