Remarks:
1
)
The parameter Behaviour DO at comm. error is apply to DC and DO channels
and only analyzed if the Failsafe-mode is ON.
2
)
The state "externally voltage detected" appears, if the output of a channel
DC0...DC7 should be switched on while an externally voltage is connected. In
this case the start up is disabled, as long as the externally voltage is connected.
The monitoring of this state and the resulting diagnosis message can be disabled
by setting the parameters to "OFF".
3
)
The error state "voltage overflow at outputs" appears, if externally voltage at
digital outputs DC0...DC7 and accordingly DO0...DO7 has exceeded the process
supply voltage UP3 Ä Chapter 1.7.5.3.3 “Connections” on page 838 (see
description in section). The according diagnosis message "Voltage overflow on
outputs " can be disabled by setting the parameters on "OFF". This parameter
should only be disabled in exceptional cases for voltage overflow may produce
reverse voltage.
