When the
VAN DER GRAAF M
k
II
is in standby (only power led on, item 1, Fig. 1, Page 9), it is
possible to activate it pushing the global enable button (Fig. 1, 1) or, when purposely set,
by sending an on/off command from an M2Tech Rockstars product’s remote control.
Immediately after this, 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 M
k
II
is active, it can be put in standby pushing the global enable
button once more or, when purposely set, by another on/off command from an M2Tech
Rockstars product’s remote control. 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 M
k
II
when it
enters standby. If the power switch (Fig. 2, 11, Page 11) is used to shut down the
VAN
DER GRAAF M
k
II
, then the sequence, even if changed from the previous standby, is not
stored and the
VAN DER GRAAF M
k
II
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 M
k
II
need to be turned on in a given order.
6.1. Setting and changing the activation sequence
Please refer to the VAN DER GRAAF
M
k
II
as it is right after delivery from the dealer, turn it
on and push the global enable button. The global enable LED turns on. No output is active
(all output enable LED ‘s are off).
Enable the first output pushing its enable button.
NOTE: the first output to be enable must not necessarily be the one labelled as ‘OUT
1’. More simply, it will be the first one that the user wishes or needs to activate.
As well, enable other outputs (all the available outputs or a part of them) in the desired
order.
NOTE: the order of activation chosen by the user will be stored by the
VAN DER GRAAF
M
k
II
when it goes in standby. Should the unit, after outputs order setup be turned off
toggling the power switch while it’s active, it will not store the sequence.
