When the VAN DER GRAAF is in standby (only LED 4 on), it is possible to activate it
pushing the global enable button (Fig. 1, 1). Immediately after this button operation,
the global enable LED (Fig. 1, 3) starts blinking and the previously enabled outputs
are activated in the order chosen by the user, at one second intervals. At the end of
the activation process, the active outputs are indicated by the related LED, which is
on, and the global enable LED glows steadily.
When VAN DER GRAAF is active, it can be put in standby pushing the global enable
button once more. Following this action, the global enable LED starts blinking and the
active outputs are shut down in the reverse order with respect to the activation order.
For example: if the activation sequence is: OUT3-OUT1-OUT2, the outputs will be
shut down in the following order: OUT2-OUT1-OUT3. At the end of the process, the
enable indication LED’s of all outputs are off and the global enable LED stops
blinking and remains off.
NOTE: the outputs activation sequence is stored by the VAN DER GRAAF
VAN DER GRAAF VAN DER GRAAF VAN DER GRAAF when it
enters standby. If the power switch (Fig. 2, 10) is used to shut down the VAN DER VAN DER VAN DER VAN DER
GRAAF GRAAF GRAAF GRAAF, then the sequence, even if changed from the previous standby, is not
stored and the VAN DER GRAAF
VAN DER GRAAF VAN DER GRAAF VAN DER GRAAF will use the last stored sequence upon following
activation, not the latest one.
The ability to activate the outputs in a chosen order is very useful whenever the units
in the chain powered by the VAN DER GRAAF need to be turned on in a given order.
