Monitoring functions / Error states
Monitoring functions are used to identify error states of the channels and the device. The
following error types are monitored on each channel and indicated by a status signal in
ibaLogic.
Shorted switch
Broken line
Over temperature
Overcurrent and shorted load
Important note
The errors "Overcurrent" and "Over temperature" always lead to a disconnection of the
respective channel triggered by the hardware. The error must be reset it by
(„ResetError_Ch[00..15]).
The errors “Broken line” and “Shorted switch” do not automatically disconnect the chan-
nel. A disconnection in case of an error can be configured in ibaPDA.
8.2.1
Shorted switch
In case a current flows although the channel is not connected logically, this error is indi-
cated.
Status signals
Possible cause
DO_Err_CurrentWhileOff_Ch[00...15]
In this case, you can suppose a hardware
problem of the channel.
8.2.2
Broken line
As soon as a current is higher than 100 mA, it is identified. If the channel is connected
on the software side, but no current is flowing or a current lower than 100 mA, the error
"Broken line" is indicated.
Status signals
Possible cause
DO_Err_NoCurrentWhileOn_Ch[00…15]
Broken cable, Load current < 100 mA
8.2.3
Over temperature
The IC load switch has reached a maximum junction temperature (T
LS
) of 150 °C. If the
temperature declines, the error is deleted at 135 °C.
Status signals
DO_Err_OverTemp_Ch[00…15]
