Fig 93.
When a scrap handling magnet attachment is fitted to the
machine, the high voltage required for its operation is
supplied by an engine driven generator. If the minimum
engine rpm is too low, the supply voltage to the magnet
may decrease to the point where any material on the
magnet may drop off. To prevent this the machine has the
capability to set the minimum engine speed so that it
doesn't fall below a predetermined level whilst the scrap
magnet is being used.
The feature can be switched on or off and the minimum
rpm set via the SET menu of the EMS by the "SCRAP
MAG" option. When this feature is enabled the throttle
volume potentiometer is re-scaled so that in the minimum
position the engine rpm is that pre-set through the
following procedure.
Set the Minimum Engine RPM for Scrap Magnet
Use
Press the SET and MODE buttons on the EMS for 5
seconds then use the scroll buttons until "SCRAP MAG" is
displayed.
Press the ACK button (this will alternate the function on/
off). Set the display to "ON", the display will change
between "MAG ON" and "MAG OFF").
Press the 'ACK' button, the display will change to "RPM
1000". Pressing the scroll buttons will then change the
rpm. value in 50 rpm. increments (allowable range to be
the low idle setting to S mode full engine speed setting for
the particular model). The default setting for the minimum
engine speed is 1000 rpm.
The rpm setting of this feature is stored and is used each
time the machine is used whilst the scrap magnet function
is enabled. The scrap magnet option is switched off
through the EMS SET menu.
If a target value less than the machines idle rpm is
selected, then the machine will default to the original Idle
setting.
