3-11.1 The Display
In the Run Mode the display will initially dis-
play:
a) Zero, if setup to reset to zero.
b) Preset number, if set to reset to preset .
c) A warning message (See Section 6-1)
The unit will accept input signals and dis-
play Rate, Batch Total or Grand total.
The Batch Total is displayed as a number.
The Rate is displayed as "R" followed by a
number.
The Grand Total is displayed as a flashing
number.
(The Grand Total flashes so that it will not be
confused with the Batch Total.)
To toggle between the Rate and Batch Total,
press the C button. Press the ENT button
at any time to view the Grand Total, then
press it again to go back to the Rate or Batch
Total.
3-11.2 Resetting (Clearing) the Totalizers.
To clear the Batch Totalizer,
a) the unit must be in the Run Mode.
b) the unit must be displaying the Batch
Total.
c) the unit must not be locked out.*
If the above conditions are met, press the
CLR (clear) button. The display should then
show the preset or zero depending on how
the unit is configured.
To clear the Grand Totalizer,
a) the unit must be in the Run Mode.
b) the unit must be displaying the Grand
Total.
c) the unit must not be locked out.
If the above conditions are met, press the
CLR button. The display should then show
zero.
* The unit may be reset if it is locked out by
putting a 3-30 VDC signal to pin 5 on the rear
of the unit.
3-11.3 Locking the Unit
The unit is shipped from the factory unlocked.
To lock the unit, it must be in the Run Mode. The
unit is shipped from the factory with a Lockout
Code of 1000.
As a test, when you receive the unit, power it
up and press 1 then 0 three times. The
display should briefly show LOCK ON. This
means that the unit is now "locked out".
Press 1 then 0 three times again. The
display should then show LOCK OFF briefly.
This means that the unit is now unlocked.
What LOCK ON or "Locked Out" means:
a) the Grand Totalizer cannot be reset.
b) only the preset can be accessed and
changed.
c) the prewarn can be accessed but not
changed.
d) the rest of the Menu cannot be ac-
cessed.
The unit will still:
e) accept input signals
f) display Rate, Batch Total and Grand total.
g) have Start, Stop and Rate/Total buttons
enabled.
LOCK OFF means that the unit functions
normally as described in this manual.
The Lockout code can be changed or viewed by
accessing Lockout in the setup Menu. (See
Section 3-3; Menu Item 4; Lockout.) The unit
must Unlocked to do this so be sure to record
any Lockout code changes in case it is forgot-
ten.
The Lock toggles back and forth from LOCK ON
to LOCK OFF each time the code sequence is
entered. The last four digits pressed, while in the
Run mode, are the ones that the unit checks for
Lockout code sequence. For example: while
1000 will unlock/lock a new unit from the factory,
so will the number 347191000 (the last four
digits are the code sequence, so, this number
works also!).
RECORD ALL LOCKOUT CODE CHANGES.
