6.0 Normal Weighing Mode Operations
This section provides the operator with a description of front panel key functions and associated annunciators
(LEDs) used to operate the UMC600 in the normal weighing mode.
After the unit is configured and calibrated, the unit is placed in the weighing or normal weighing mode (SW1-1
through SW1-4 open). In this mode, the weight indicator displays live weight data that is presently on the scale.
6.1 Display Test
The display check and EPROM verification are used to
test the indicator LED.
6.1.1 Display Check
Observe the display when power is first applied to the
indicator. All six indicator LEDs (zero, net, gross, lb,
kg, and motion) should be turned on and each seven
segment display, with its associated decimal point, will
advance across the display field, allowing the operator
to check for any missing segments or decimal points.
6.1.2 EPROM Verification
Upon completion of the display check the software
version momentarily appears on the display. This value
indicates to the operator the current EPROM that has
been installed in the UMC600. The UMC600 operates
with an EPROM family group KDA 1.15.
6.2 LED Annunciators
Table 6-1 shows the display panel annunciator and the
definitions of the annunciator.
6.3 Function Keys
Table 6-2 describes the various functions of the
UMC600 keys.
6.4 Gross/Tare/Net Weighing
Operations
In normal mode, the UMC600 displays gross, tare, or
net weights using the LED annunciators to indicate
scale status and the type of weight value displayed.
6.4.1 Display Mode on Power Up
When the UMC600 is initially powered up, the display
automatically appears in the gross mode.
6.4.2 ZERO Key Function
If the gross weight zero is within the zero band, press
the
ZERO key. There are various things that would
make invalid zero conditions. They are:
• Gross weight data above the defined zero band
• Gross weight data in motion
• Overload/underload condition
Annunciator Annunciator Definition
ZERO On when gross weight data is within ±1/4
graduation of the center of zero
NET On when indicator is in net weighing mode
GROSS On when indicator is in gross weighing mode
lb/kg Shows units of displayed weight data
MOTION On when display data is changing by the
number of graduations selected in parameter 9
in configuration mode
Table 6-1. Annunciator Definitions
Key Functional Description
ZERO Returns scale to zero if the gross weight is
within the band of zero selected in the
configuration mode (1.9% or full scale)
GROSS
NET
Selects the desired weight data to be viewed
(GROSS or NET). The gross and net LED
annunciators indicate which display mode is
active.
TARE When used in the gross mode, the indicator
will acquire the tare value and automatically
shift to the net display mode. If a tare
acquisition is negative or the weight data is in
motion, the indicator remains in the present
mode and no tare is performed.
UNIT If the indicator is set up to perform lb/kg
conversion, this key toggles weight data
between its calibrated base weight unit in lb to
kg units. The lb and kg annunciator LEDs
indicate which units are displayed.
PRINT Issues a demand print command to the serial
output.
