Unit description

Bestimmung/Gertebeschreibung_Muting_PDB

The muting controller meets the re­quirements of EN 60204-1.
It may be used in safety circuits which
temporarily suspend safety functions
(muting), in accordance with
EN 61496-1.

Safety features

][Sicherheitseigenscha ften Schaltgerät_allgem einer Teil

The relay meets the following safety
requirements:

` The circuit is redundant with built-in

self-monitoring.

` The safety function remains effec-

tive in the case of a component fail­ure.

` The correct opening and closing of

the safety function relays is tested
automatically in each on-off cycle.

Wiring

][Verdrahtung_Si_unverz_1Hi_unverz

Please note:

` Information given in the “Technical

details” must be followed.

` Outputs 13-14, 23-24, 33-34 are

safety contacts, output 41-42 is an
auxiliary contact (e.g. for display).

` To prevent contact welding, a fuse

should be connected before the
output contacts (see technical de­tails).

` Mechanical and optoelectronic

sensors (safety light barriers, safety

` The safety contacts can be used to

shutdown the hazardous move­ment.

` Only safe contact outputs (e.g. from

safety light barriers) may be used
on S51-S52 and S61-S62. Do not
connect safety light barriers to
semiconductor outputs.
