The status signal contact of K1 (NO contact) to the monitoring circuit is constructed with mechanical
with the NC contacts connected contacts. The selection of the contactor takes place after its limiting
short-time current load capability (10 ms). This must be bigger than the nominal current of the used
semiconductor fuses at the mains input of the converter.
y S1 (NC contact) has hardware effects on the safety relay of the converter. Only then if S1 displays
a closed barrier (and therewith a safe condition) voltage is applied to the safety relay input (X68: 3)
and therewith makes a torque generation at the shaft of the motor. The NO contact of S1 is connect-
ed with the monitoring circuit.
y S3 (NO contact) has hardware effects on the impulse release input of the converter (X26: 14). Only
if S3 displays a closed barrier (and therewith a safe condition) voltage is applied to the impulse re-
lease input of the converter.
y The monitoring circuit, a fail-safe monitoring control of the category 4 (EN 954-1), checks on its own
the directly connected switch contacts of the position switches S1 (NO contact), S2 (NO contact), S3
(NC contact) and the status signal contact of the safety relay (X68: 1,2; NC contact) as well as the
contactor K1 (NO contact). If the barrier is not completely closed or a theoretic impossible condition
of the position switch contacts is present (for example S1 and S2 show a different switch condition
or S2 and S3 show the same switch condition or the status signal contact of the safety relay is
opened/closed, although the status signal contact of S1 is closed/opened), the control circuit re-
ceives no release signal of the monitoring signal. A missing release signal of the monitoring device
leads to a direct switching off of the converter by means of the control circuit. If the monitoring circuit
has recognized an error (for example different switch condition of S1 and S2), this if displayed to the
operator and the commissioning of the drive is not possible until the error has been repaired.
y The position switches, which are used, must unavoidable have actuated and mechanical connected
contacts as well as a dual-port connection (NC contact/ NO contact). The mechanical operating at
the safety device must take place unavoidable, that means tamper-resistant.
The connection cables between the contactor K1 and the control circuit as well as between the safety
relay input at the converter (X68: 3,4) and the control circuit must not be installed outside the switching
cabinet in a common cable channel.
6.4.4 Service time
The mechanical service time of the safety relay is at least 1 x 10
7
cycles of operation.
NOTE
All information given in the Operation Manual of the converter, especially the chapters safety instruc-
tion, installation and commissioning, must absolutely be observed.
For the use and the installation of the safety devices the legal and official requirements of the gov-
ernment safety organizations and of the EU-Directives for safety requirements at installations and
machines (for example EN 60204-1, security of machines, electric equipment and EN 292-2 security
of machines general configuration directives) are valid.
