F2.2 Auto Clear Tare
Causes the tare value to be cleared automatically when the scale returns to zero. Use this
to force entry of a new tare weight for each container being used (such as in a recycle
center application, where you have multiple bins).
F2.3 Ten Tare Look -up
Enables the storage of up to ten (10) tare values. You can use this to store the tare values
for several containers and retrieve them by register number as needed.
F2.4 Battery Back-up Enable
Prevents values in the random access memory from being cleared by a power-up
sequence. This consists of ID numbers, Consecutive Numbers, tare values, preset,
dribble, preact, totals, etc. Revision “D” and higher mother boards have a 24-hour back-
up circuit built-in. This can be extended to approximately ten (10) years on all mother
boards with an addition of a time/date module.
F2.5 Stand-by Mode on Power-up
Will cause the display annunciator arrows to light upon power-up. The display will be
disabled until either the [ZERO] or [TARE] buttons are pressed. Required by “Weights
and Measures” in some areas to show that a power failure has occurred.
F2.6 External Gross/Net Enable
When enabled the front panel [GROSS/NET] button will not operate. The system will
instead take an input (contact closure) from TB1-3 of the mother board. Unlike the front
panel switch this input is closed for net and open for gross.
F2.7 Two-Speed Feed
Part of the preset function, enables the [DRIBBLE] button on the front panel. The value
in the dribble will be subtracted from the preset, and used to operate the two speed relay
function. If enabled there are three (3) presets, disabled there are six (6).
F2.8 Sequential Feed
Controls how the output relays (connected to J7) operate during two-speed feed
operation. When disabled, both the slow and fast feed relays are energized initially. The
fast feed relay is de-energized when the weight reaches the preset minus the dribble
value. The slow feed relay is de-energized when the preset weight minus the preact is
reached.
