selected current setting and are not adjustable.

Tips:

The Output Load and Output Current values are transmitted via CAN so

that they can be logged by another device. Check the logged Output
Load value to ensure it is not too close to 100% during normal
operation and during start-up.

The Output Load and Output Current values can also be monitored

using PDM Manager. See Checking Operation.

Fault Shutdown

A Fault Shutdown occurs when the output voltage is lower than expected.
This can be caused by a short circuit or thermal overload of the output.

A short circuit may cause a Fault Shutdown before the Over-Current
Shutdown occurs.

To configure an Output Pin

In the Configuration Tree, select Output Pins

Double click the output to setup

Type a channel name and select settings as required

Maximum Current

This sets the current at which the output will shutdown. The output current
may exceed this value for a period of time which allows for the start-up
(inrush) current of devices such as motors and lamps.

The maximum current can be set to 10 ampere on the 8 Amp outputs and
25 ampere on the 20 Amp outputs to be clear of the normal running
current, even for devices that draw the maximum specified current of 8 or
20 ampere.

Number of Retries and Retry Delay

When an Over-Current Shutdown or a Fault Shutdown occurs, the PDM
will attempt to turn the output on again if the Number of Retries is
configured. The Number of Retries determines how many times an output
will attempt to turn on again.

The Retry Delay determines how long an output remains shutdown before
it is turned on again.

The retry count for an output is reset whenever the condition driving the
output changes to FALSE and then to TRUE (i.e. when the condition
