c) SAFE Z
Connection plan
Two hand control relays SAFE Z according to
BG,
section iron and metal III ZH 1/456 (o2.78) and
DIN EN 574 (02.97) for type I - III c.
Suitable up to category 4; SIL3; PLe reachable
Operate mode
There must be installed an auxiliary voltage at
the terminals A1 and A2 in order to operate the
device.
Then power LED starts illuminating. By pressing
the button S1 simultaneously to S2 the safety
outputs 13-14 and 23-24 will switch. This causes
an machine connected to the safety outputs gets
able to start.
Attention: The simultaneous of the two hand
control button S1 and S2 has to be smaller 0,5
sec.
If one or both buttons released, the outputs 13-1
simultaneous and 23-24 will open
immediately.Only after releasing S1 and S2 a
new cycles can be started. If the simultaneous
time will be bigger than 0,5 sec the outputs will
not be released. The outputs 13-14 and 23-24
stay open. The machine cannot be started.
It is possible to connect machine-release-circuits
at the terminals S21 and Y2.
The contact extension have to get export.
