4.2 Auto Setup
There are various features available in Automatic mode. These should be reviewed and set up to best
reflect your operation and needs. The setup can be changed at any time should the need arise.
4.2.1 Auto Setup – Setting Speed Limits and Delay time
Press the “ Touch area ” <Max safe Speed> to display the numeric
touch pad data entry screen for setting the maximum speed.
Press the “ Touch area ” <Min safe Speed> to display the numeric
touch pad data entry screen for setting the minimum speed.
Press the “ Touch area ” <Hi/low delay Time> to display the numeric
touch pad data entry screen to set the delay before changing the
speed. Time is in seconds.
Press the “ Touch area ” <Norm Spd. delay Time> to display the
numeric touch pad data entry screen to set the delay before changing
the speed back to normal speed. Time is in seconds.
Press the “ Touch area ” < Exit > to return to the Main screen.
Press the “ Touch area ” <Next > to continue to the next menu screen.
Figure 22. – Auto Setup – Speed limits and delay time
How the speed limits and delay time work:
The Speed limits and delay times serve as constraints to ensure safe and reliable operation. These
should be set with care and possibly experimentation to ensure optimum performance
1) Max Safe Speed – This is the maximum speed your drying system can operate at. Before
setting this speed consider the takeaway and feed systems to ensure this setting will not
overload the equipment. Also look at the real operation. If you know your dryer should never
operate above 70 for any reason this should be set to 70 or possibly less.
2) Min Safe Speed – This is the minimum speed your drying system can operate. Same as before
there is a minimum speed below which the system should never need to operate.
3) Hi /Low Delay Time – This is the time in seconds the moisture has to be either above the “high
limit moisture target” or below the “low limit moisture target” before the speed will change to
either the “low speed setpoint” or the “high speed setpoint”
. Time is in seconds, 300 seconds is
5 minutes. 999 seconds or about 16 minutes 39 seconds is the maximum delay available.
4) Norm Spd Delay Time – (Normal Speed Delay Time) This is the time in seconds the moisture has
to have returned to normal (the window between the “high and low moisture target”) or have
moved to the other side of the target moisture ( mode dependent) before the speed is again
returned to normal mode. 999 seconds or about 16 minutes 39 seconds is the maximum delay
available.
