NOTE: Once the EZ PRE mode is entered, the internal LOCK is automatically turned on. The only way to get back
to the menu is to enter the lockout code. See page , `Locking and Unlocking the Unit’.
NOTE: If the STOP is activated before a batch is complete, pressing START will continue the batch from the point
where it was stopped. If a new preset is desired after activation of a STOP, the CLR button may be pressed to clear
out the remaining count and a new PRESET value can be entered.
OPERATION USING STD PRE:The STD PRE (standard preset) programming option has been used in the past in
our batching units. When the STD PRE option is selected, the unit operates as follows:
The Preset and Prewarn values are entered by entering the programming menu and selecting Preset and
Prewarn. After these values are entered, the user can reset the counter (front panel or remote) and start
the batcher. When started both relays energize, and the counter begins to count. When the batch is
complete the relays drop out and the unit displays the amount that was batched (0 if set to preset mode).
To run a batch of the same amount, the user must reset the counter and press start. To run a batch of a
different value, the user must enter the programming menu and enter the new Preset and Prewarn values.
The counter must be reset before the new batch is started.
K-FACTOR: A user selectable K-Factor is used to convert the input pulses into engineering units. The value to
enter is the number of pulses per unit volume.
16-POINT LINEARIZATION: The 16 point K-Factor selection allows the user to program in from 3 to 16 different
frequency points (inputs per second) and different K-Factor dividers from 0.0001 to 999999999 for each of these
frequencies.
The 16 point unit determines the incoming frequency and calculates a K-Factor line slope from the two
closest data points that had been entered. The `specific K-Factor’ is then proportionally interpolated using
8-position floating math. This K-Factor is applied to all inputs until the next frequency calculation, usually 1
second later. If a `0’ frequency is entered into `point 1’ the ‘point 1’ K-Factor will be applied to all inputs
received before the first frequency calculation.
The rate can be displayed in 3 ways: `SECONDS_’, `MINUTES_’, `HOURS_’. If `SECONDS_’ is selected
the unit displays the `base’ rate calculated from the incoming frequency and the ‘specific K-Factor’. If
‘MINUTES_’ is selected, the rate displayed is 60 times the ‘base’ rate. If ‘HOURS_’ is selected, the rate
displayed is 3600 times the ‘base’ rate.
COUNTER: The total counter has 8 digits. In the set-up mode choose ‘RO’ (reset to zero) for adding operation or
`SP’ (set to preset) for subtracting operation..
COUNT INHIBIT: A user selectable temperature or density range which can be used to inhibit counting outside a
given range.
RATEMETER: Accurate to 5 1/2 digits (+/-1 display digit). The rate meter can be programmed to accept almost any
number of pulses per unit of measurement, perform a weighted averaging function to stabilize fluctuating displays
and autorange up to 6 digits of significant information. The unit will update each second. The 2 to 24 second
`WINDOW’, selected at set-up, is the maximum time the unit will wait for sufficient input pulses to make an accurate
calculation before it displays zero. The rate meter with a K-Factor of 1 displays the rate of pulses per second.
Simply dial in the proper K-Factor to display in minutes, hours or other units of measurement. Press the `C’ button
to display the rate, total, temperature, preset or density.
LOCKOUT: Unauthorized front panel changes can be prevented by entering a user selected 4 digit code.
OUTCARD: RS232 or RS422 serial two way communication options are available. Up to 15 units can be linked
together and addressed separately to transmit unit status or accept new set points in the standard ASCII format.
Baud rates of 300, 600, 1200, 2400, or 9600 as well as choice of odd, even, space or mark parity can be selected
by keypad control.
