Description
1: Switch on high voltage
0: Switch off high voltage
1: All errors are confirmed
0: No action
Note: In order to switch on HV
again, after an error has been con-
firmed, the "HV ON" bit must be re-
set/set.
The smart-E expects a heartbeat
signal (1Hz) via the PROFINET.
This monitoring is initially deactivat-
ed and is then activated with the first
heartbeat.
If a heartbeat never comes then the
HV generator can be operated with-
out it.
As soon as the heartbeat comes
once, this is monitored and if it re-
mains off the generator shows an
error.
1: Open the safety relay
0: No action / close relay
Note: The safety relay is controlled
by the HV generator depending on
the remaining voltage on the HV
connection.
If the contact is found in the "safe"
position (closed), it can be opened
with this Bit for test purposes.
Note: When the relay test bit is set,
the HV cannot be switched on.
