The Card Test Input is provided so that the user can access the Card Test feature
remotely. One end of a normally open SPST switch is connected to this termination. The
other end is connected to system common. To activate the feature, simply press and
hold the switch for as long as the test time is to be run. (runtime is 3 or 10 seconds,
software selectable)

NOTE -
If the Analog Signal is not used a jumper must be placed between 20d & 22d. If
required to test card at full load, add 300ohm 1% resistor between AO+ and AO-.
