4520 Installation Manual
1.3.14 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

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 (see Section 6.0 on page 47).
1.3.16 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 or PRINT 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.
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.

used for wiring the Ethernet option card (PN 71986)
to the 520 indicator.
2.4.6 Digital I/O
Digital inputs can be set to provide many indicator
functions, including all keypad functions. Digital
inputs are active (on) with low voltage (0 VDC),
inactive (off) at 5 VDC. Use the DIG IN menu to
configure the digital inputs.
Digital outputs are typically used to control relays that
drive other equipment. Outputs are designed to sink,
rather than source, switching current. Each output is a
normally open collector circuit, capable of sinking
250 mA when active. Digital outputs are wired to
switch relays when the digital output is active (low, 0
VDC) with reference to a 5 VDC supply.
Use the SETPTS menu to configure digital outputs.
