Safety circuit
7.1
Basic principles
The safety circuit supports various configurations and makes an additional safety PLC
or safety relay superfluous for certain applications.
Monitored warning lights are also supported.
The safety circuit can be used from IO-CPU Version 33504 and
ETL DataView 3
from Version 3.35.70.261 , the .Net Assembly from Version 5.2.0, the Windows API
DLL from Version 5.2.1 (in preparation), LabVIEW drivers from Version 5.2.1 (in
preparation) or ASCII commands from Version 2.1.
The safety circuit consists of the safety circuit board, which performs the safety-
related functions, and the baseboard, which connects to the basic device.
These two boards must not be separated under any circumstances.
DANGER
If a fault is detected by the safety circuit, it enters the safe state FAIL SAFE.
The machine must not be operated if the cause of the safe state (FAIL SAFE) is still
present or if the displayed error message repeatedly indicates an internal error.
Maintenance
Maintenance work must be carried out every six months.
The necessary work must be carried out by a qualified electrician.
Further information can be found with the respective configuration.
Note
1.
The connectors for the warning lamp combination and the safety circuit
have changed. Adapters are required to connect existing accessories (e.g.
test cage or two-hand operation).
2.
The warning lamp combination must always be provided with a plug, even
if no warning lamps are connected, as the configuration must now always
be detected.
3.
The safety circuit must always be provided with a plug, even if a safety
circuit is not necessary due to the type of test used (e.g. protective
conductor test), since the configuration must now always be detected.
4.
If the plug of the safety circuit or the warning lamp combination is
removed and plugged in again, the new configuration must be determined
again. To do this, press the
Reset SC
button in
ETL DataView 3
in
Service
->
Safety circuit
or switch the device off and on.
