5.2 TOTALISER CONFIGURATION (Cont.)
PRESET
TT1 Preset
XXXXXXXXX
This display is present only if ‘Preset Up’ or ‘Preset Down’ is the chosen type. A preset-up type counts up to this
value, outputs its internal trigger and then stops until reset. A preset-down type counts down from this number
until it reaches zero. It then outputs its internal trigger and stops until reset.
LOW CUTOFF
TT1 Low Cutoff
_0.000 Units
Some Measured Values are not meaningful near the low end of their range and some become negative when their
input is turned off. To avoid totalising these inaccurate signals, a low cutoff value (in measured value units) can be
entered. Totalisation stops below this value. The up/down/side arrow keys are used to enter the low cutoff value.
HIGH CUTOFF
TT1 Hi Cutoff
_^^^^^^. Units
The high cutoff stops totalisation above the entered cutoff Value. The default setting is the over range value
(^^^^^). The high cutoff is set using the up/down/side arrow keys .
TOTALISER RESET
TT1 Resettable
No
This choice determines whether a totaliser can be reset. As long as this password-protected choice is NO, the
totaliser cannot be reset. Action equation and operator menu choices have no effect. The up/down arrow keys
are used to change this choice.
TOTALISER RESET ACTION EQUATION
TT1 Rset Eq ?
The ENTER key is used to review or change the action equation that controls the totaliser reset. This action
equation defines which internal triggers are to be used to reset the totaliser. See Section 3.4 for a discussion of
internal triggers and action equations.
A totaliser can be reset by its own trigger, making it possible for a preset totaliser to re-start automatically after it
has reached its preset value. The same internal trigger that starts a log can reset a totaliser each week, day, shift,
etc. The up/down/side arrow keys are used to enter internal triggers.
