Within a time interval, selectable between 0.15 to 155 msec, from switching the output ON, the
current draw must have fallen below the OCL threshold. This threshold can be set to 30 / 40 A.
In column “
INIT ms”
key in the time delay for applying the steady state fuse level defined in “
NORM
mA”
. This interval must exceed the time interval selected for OCL, suggested value > 200 msec.
Maximum time is limited to 10 seconds.
After the time interval INIT, the initial time from switching the output ON, the current draw must be
below the user defined software fuse level, OCS. If the current draw exceeds this threshold, the
output will be switched off.
In
SW Time
set the time interval in milliseconds during which the current draw is allowed to exceed
the OCS fuse level.
Time intervals are selectable from 25 ms to 250 ms.
In column
NORM mA
key in the steady state fuse level required. This value must be lower than the
maximum fuse level, OCL. Maximum current threshold is 26,000 mA.
If the current draw on an output exceeds the NORM fuse setting, the output will switch off.
In
Retry
set the maximum number of automatic re-activation of an output channel after is has been
shut down caused by a short circuit or an overload. It is strongly recommended not to exaggerate
the number of retries – select a number < 10.
In
Retry ms
set the time interval between retries in milliseconds.
The status window will show the real time current draw of the output in mA.
Use the
Manual
option to test the output connection. When
Manual
is active (see section
4.3
),
PCM2’s event handling has been deactivated and all channels are OFF by default.
Click the ON button for each individual channel to switch the output ON.
Click the ON button again to switch the output OFF.
Clicking on
Trigger
will open the main event controlling this output. A warning may appear if
several events are used to control it.
