another accumulation is allowed.
1.3.15 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 (see Section 6.0 on page 42).
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 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 will remain
in gross, but the net peak weight will be 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.
Normal (Positive Peak, Manual Reset)
This is the basic peak hold function in which a weight
is applied to a scale and the greatest net weight value
is held in memory until the weight is removed from
the scale, and either the ZERO or PRINT key is
pressed. If the display is in gross mode, the peak net
weight can be displayed by toggling to the net mode
with the G/N key.
Bi-Dir (Bi-Directional Peak, Manual Reset)
This is the same as NORMAL parameter setting
(above), except that the peak can either be a positive
or negative number, determined by the absolute
weight value. This means that if a positive peak is
displayed, a negative weight value of greater absolute
value can update the peak information in the same
cycle.As above, the peak cycle is reset by pressing the
ZERO key after the weight has been removed.
Auto (Positive Peak, Auto Print, Auto Reset)
This is the same as NORMAL parameter setting
(above), except that automatic print occurs when the
scale load is reduced to 0 ± 10 display divisions and
the scale achieves standstill. Following the print
command, the peak value is cleared and reset
automatically. As in the above two modes, the peak
hold value can also be cleared by the ZERO key, or by
a manual press of the PRINT key.
The digital display can be set to display gross weight
information data using the G/N mode key during peak
hold function cycles.

Introduction 5
NOTE: The following front panel entry modes will
timeout after 10 seconds if there is no activity:
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.

2.3.2 Serial Communications
To attach serial communications cables, remove
connector J5 from the board. Connector J5 provides
connections for the EDP (Electronic Data Processing)
port, printer port, 20 mA current loop transmit signals,
and RS-485 signals. Table 2-2 shows the pin
assignments for connector J5.
Once cables are attached, reconnect J5 to the header
on the board.
The EDP port supports RS-232 or RS-485
communications; the printer port provides active 20
mA output and full-duplex RS-232 communications.
Both ports are configured using the SERIAL menu.
See Section 3.0 on page 14 for configuration
information.
2.3.3 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.
Table 2-3 shows the pin assignments for connector J4.
2.3.4 Analog Output
If the optional analog output module is installed,
attach the output cable to connector J1 on the analog
output board. Table 2-4 lists the analog output pin
assignments.
Use the ALGOUT menu to configure and calibrate the
analog output module when cabling is complete. See

2.8 Battery Replacement
The lithium battery on the CPU board maintains the
real-time clock and protects data stored in the system
RAM when the indicator is not connected to AC
power.
System RAM data includes prompts and keyboard
locks. This information is lost if the battery loses
power and the indicator is disconnected from AC
power. To prevent loss of data, do the following:
•When battery voltage gets low, the indicator
display shows low bat. Replace the battery when
this warning is displayed. The battery should
last seven years.
•Use the Revolution™configuration utility or
EDP commands (see Section 10.1 on page 46)
to store a copy of the indicator configuration on
a PC before attempting battery replacement. If
any data is lost, the indicator configuration can
be restored from the PC.
There is a risk of explosion if battery is
replaced by an incorrect type.
NOTE: Dispose of battery per manufacturer
instruction.

3.1 Configuration Methods
The 520 indicator can be configured by using the front
panel keys to navigate through a series of
configuration menus or by sending commands or
configuration data to the EDP port. Configuration
using the menus is described in Section 3.1.3.
Configuration using the EDP port can be
accomplished using either the EDP command set
described in Section 10.0 or Version 2.7 or later of the
Revolution™configuration utility.
3.1.1 Revolution Configuration
The Revolution configuration utility provides the
preferred method for configuring the 520 indicator.
Revolution runs on a personal computer to set
configuration parameters for the indicator (see
Section 5.0 on page 40). When Revolution
configuration is complete, configuration data is
downloaded to the indicator (see Section 5.3 on
page 41). Figure 3-1 shows an example of one of the
Revolution configuration displays.

3.1.2 EDP Command Configuration
The EDP command set can be used to configure the
520 indicator using either a personal computer or
terminal. Like Revolution, EDP command
configuration sends commands to the indicator EDP
port; unlike Revolution, EDP commands can be sent
using any external device capable of sending ASCII
characters over a serial connection.
EDP commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. EDP commands can
be used to simulate pressing front panel keys, to
configure the indicator, or to dump lists of parameter
settings. See Section 10.0 on page 46 for more
information about using the EDP command set.

3.1.3 Front Panel Configuration
The 520 indicator can be configured using a series of menus accessed through the indicator front panel when the
indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.
Figure 3-2. Five-Key Keypad Functions in Setup Mode
Four front panel keys are used as directional keys to navigate through the menus in setup mode (see Figure 3-2).
The UNITS ()and PRINT ()keys scroll left and right (horizontally) on the same menu level; ZERO ()and
GROSS/NET ()move up and down (vertically) to different menu levels. The TARE key ( ) serves as an Enter
key for selecting parameter values within the menus. A label over each of these keys identifies the direction
provided by the key when navigating through the setup menus.
