OPERATING MODE = PEAK
PRESET COUNTERS = 1 for each relay
LOWEST LO TONS = 100.0 in each channel
CNT HI SETPOINT = 200.0 in channel 0
All other data is set to 0.
Before using the N269 meter to accurately monitor tonnages the following must be done:
1. Enter press CAPACITY including the proper DECIMAL POINT location
2. BALANCE each channel
3. Set calibration numbers in each channel
These 3 steps will have been done during calibration. You may wish to verify that the proper
numbers have been entered if this is the case. Once the CAPCACITY is initially entered it will
never need to be re-entered unless the memory is lost. (i.e. battery fails for some reason).
E. INITIAL SETTINGS
1. DECIMAL POINT LOCATION - HIGH HIGH HIGH [. (0-3) ENTER]
To display the number of DECIMAL PLACES press the key sequence HIGH-HIGH-
HIGH. A single digit appears in the left portion of the channel 0 display. This digit
indicates the number of decimal places to the right of the decimal point in the displays.
The number can be 0 (in which case no point is displayed), 1, 2 or 3 places.
To change this number, press the decimal point key. This digit only will now be lit. Press
the number key (0-3) which corresponds to the number of decimal places desired. Now
press the "ENTER" key. The display will now show the CAPACITY again.
2. PRESS CAPACITY - HIGH HIGH HIGH [ #(0-2) (DATA) ENTER ]
Press capacity is displayed by press the key sequence HIGH-HIGH-HIGH. The
capacity of each channel is displayed in that channel. New values may be entered by
selecting a channel (0-2), entering the data value, pressing keyboard DIPSWITCH #31-8
down and then up (see Fig. 6), and pressing ENTER. For meters with only one input
device, the press capacity gets entered into channel 0. If two sensors are connected, the
capacities entered into channels 1 & 2 should be half of press capacity.
Upon power up if the CAPACITY has not yet been set, each channel is set to the value
100.0 to indicate percentage. THE DISTRIBUTION CHANNELS WILL NOT ADD
UP PROPERLY UNTIL CAPACITIES ARE ENTERED IN CHANNELS 0-2.
3. TRIGGERING THE METER
a. THE THRESHOLD - LOW LOW LOW [ 0 (VALUES) ENTER]
The N269 meter must be triggered to know when the load signal is applied and then
