Readback Time Parameter
Each output channel has its own selectable readback time. This time specifies the maximum
duration of the turn off test for the corresponding channel and therefore also the readback
time for turning off the channel.
The following readback times can be set: 1 ms, 5 ms, 10 ms, 50 ms, 100 ms, 200 ms and
400 ms.
You should set an adequately high readback time if the channel involved switches high
capacitive loads. If the readback time for a controlled capacitive load is set too low, the
output channel is passivated because the discharge of the capacitance does not take place
within the turn off test.
If the readback signals are incorrect, the "short circuit" fault causes passivation of the output
channel after the readback time elapses.
