Rice Lake 520 Digital Weight Indicator Operator Card - Manual (Page 3)

Note
3 520 Indicator Operator Card
• If the checkweigh function is enabled,
setpoints remain configured but do not
function until checkweigh is disabled.
• Some indicator configurations may not allow
checkweigh values to be changed through the
front panel or may require a password to
display or change the checkweigh value.
2.1.12 Set Date
In front panel setup mode use the arrow keys to toggle
to Date . Press DOWN or ENTER to enter the date in the
format configured for the indicator: MMDDYY,
DDMMYY, or YYMMDD.
2.1.13 Set Time
In front panel setup mode use the arrow keys to toggle
to Time . Press DOWN or ENTER to enter the time in
24-hour format, then press the ENTER key.
2.1.14 Display Accumulator
The accumulator must be enabled before use in either
normal mode or setpoint operations. Once enabled,
weight (net weight if a tare is in the system) is
accumulated whenever a print operation is performed
using the PRINT key, digital input, or serial command.
The scale must return to zero (net zero if a tare is in the
system) before the next accumulation.
1. Press and hold the G/N key for three seconds to
display the accumulated value if accumulator
is enabled.
2. Press the UP key to clear the accumulator or
the PRINT key to print the accumulator.
Note
The
PRINT
key only performs one
accumulation. Weight must return to zero
before another accumulation is allowed.
2.1.15 Count Display Mode
Count mode is entered by pressing the MODE
(GROSS/NET) key from normal weighing mode when
count mode is enabled. In count display mode, the
display shows the number of parts rather than weight.
The annunciator at the right side of the LCD display
reads piece count (PC). Pressing the PRINT key sends
the CFMT print format data string to the serial port.
If a sample weight has not yet been acquired, the
indicator switches automatically to sample acquisition
mode.
2.1.16 Peak Hold Mode
The peak hold function is used to determine, display,
and print the greatest net weight read during a
weighing cycle.
A weighing cycle ends when the print command is
given, or when the peak net weight is manually cleared
by the ZERO key. Peak hold tracks only net weight and
operates independently of the display. For example, if
the indicator is displaying gross weight, but AUTO
peak hold is active, the display remains in gross, but
the net peak weight is automatically printed when
standstill is achieved at net zero.
Peak hold function is enabled in the setup mode.
Parameter settings are found under the PK HOLD
submenu, in first level program menu.
Note
Setpoint, time and date, and checkweigh value
changes from weigh mode (press and hold the
UNITS
key), accumulator display (press and
hold the
G/N
key), keyed tare display (press and hold the
TARE
key), and password entry front panel entry modes
timeout after 10 seconds if there is no activity.
