f. THE B4 MODE
The B4 mode is a combination of the normal peak mode and first level mode. This mode
is meaningful only for presses with more than one sensor input. When selected the B4
mode displays the distribution forces at the first level time in channels 1 and 2. Then
when the punch finishes the stroke the total load is displayed in channel 0. In this way
setpoints may be set on the first level load using channels 1 and 2 as well as on the total
load using channel 0 for the same stroke of the press.
To select the B4 mode the meter must be in TIME mode 0. Press the keys RESET
TIME. The display will now show the TIME VALUE in channel 0 and the TIME mode
digit to the left of the TIME VALUE. Press the DEC. PT. key and then the 0 key.
Press the ENTER key to enter the number. If the TIME LED is lit just press RESET to
display loads again. If the TIME LED is not lit press the TIME key twice and then
RESET. Once the TIME LED is lit the meter is in TIME mode and with TIME mode
and with TIME mode 0 selected the display shows B4 loads.
Setpoints will now apply to the loads which are displayed. This means that channels 1 and
2 cover the distribution load and channel 0 covers the total load. Therefore the process
control is on the basis of the total load when in B4 mode. For more information about the
TIME VALUE refer to its own discussion elsewhere in the manual.
3. AVERAGE LOADS
The N269 meter can be set to display the average of the previous 16 press strokes rather than
displaying each stroke if desired. Averages for any operating mode can be shown, but only the
average of the present operating mode is calculated for each press stroke. This means that it will
require 16 strokes in a particular mode before the meter will be showing accurate averages.
When the display is showing average loads the high and low setpoints trigger off of these
averages for alarms. The process control setpoints use the channel 0 average load to determine
the zone of the signal.
To enter the averaging mode, press the key sequence LOW COUNT DEC PT. (.). The meter
display will show a single digit in the left portion of the channel 0 display. This digit will be a 0
when the meter is NOT in the averaging mode. To put the meter in average mode press the 1
key. Then press the ENTER key. After 13 seconds elapses or after RESET is pressed the
meter will show the average load of the last 16 strokes. In the far left portion of the channel 0
display the "L" will appear to indicate that the meter is displaying average load.
To go back to displaying normal loads use the above procedure to set the single digit
average number back to zero.
