steel conduit with pull boxes located at required intervals. The conduit provides additional noise protection for the
low-level signals, while automatically complying with the requirements for two-inch separation between
intrinsically safe circuits and other electrical cables. Conduit seals are necessary where a gas tight seal is required
between hazardous area and safe area.
2.3.3AC Power Wiring
Standard units are powered by an F.M. approved power supply. We recommend the 100–240 VAC into RLWS
IS-EPS-100-240 Intrinsically safe DC output power supply (PN 72713).
See the IS-EPS-100-240 Power Supply Instruction Sheet (PN 79820) for information on wiring and power
specifications.
2.3.4Battery Option
The optional battery pack provides an intrinsically safe battery that can replace the power supply. The battery is
approved for use in hazardous environments and limited use operations such as bench scales and platform scales. A
low battery error message will display to indicate that the battery needs to be recharged. Always charge the battery
overnight. The yellow indicator light will remain on until the battery is charged at about 70%, at which point the
indicator light will turn green and the charger will switch to float charge mode. Once the light turns green, the
battery requires another 3 hours on float charge before the battery is fully charged.
To keep battery at full capacity, it is recommended to leave the battery connected to the charger, in float
charge mode, until ready to use. The battery can remain on the charger in float charge mode indefinitely
without damaging the battery. See Battery Charging Instruction Sheet (PN 96567) for instructions on charging
the battery.

2.5Fiber Optics Installation
The 320IS is equipped with a duplex fiber optic port for communicating with an I/O Module located outside the
hazardous area. This is the only communications channel of the indicator. The indicator communicates with
external devices through the optional I/O Module’s physical interfaces (RS–232, RS–422, RS–485, Current Loop)
and provides analog and digital I/O functions such as setpoint relays and analog outputs.
The fiber optics port is located on the indicator CPU board (see Figure 2-5).
2.5.1Assembling Fiber Optics Connectors
Use the following steps for assembling the fiber optic connectors of the 320IS:
1. Cut off the ends of the fiber optic cable (PN 74000) with a single-edge razor blade or hot knife (PN 85548).
Try to obtain a precise 90º angle.
2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal
micro-lens.
3. Screw the connector locking nut down to a snug fit, locking the fiber in place.
4. Secure fiber with 3-inch nylon cable ties in parts kit and 3/4-inch square nylon mounts.
Figure 2-7. Fiber Optics Connector
2.6Enclosure Reassembly
1. Position the backplate over the enclosure.
2. Reinstall the backplate screws. Use the torque pattern shown in Figure 2-8 to prevent distorting the
backplate gasket. Torque screws to 15 in-lb (1.7 N-m).
Torqued screws may become less tight as the gasket is compressed during torque pattern, therefore a
second torque is required using the same pattern and torque value.

Note
To configure the 320IS indicator, the indicator must be placed in setup mode. The setup switch is accessed by
removing the large fillister head screw on the enclosure backplate. Setup mode is enabled by inserting a
non-metallic screwdriver into the access hole and pressing the pushbutton configuration switch.
SERIAL, PFORMT, DIGIN and ALGOUT functions require fiber optics communications with I/O module in order
to operate.
When the indicator is placed in setup mode, the word CONFIG is shown on the display. The CONFIG menu is the
first of nine main menus used to configure the indicator. See
complete, scroll to the CONFIG menu then press the (ZERO) key to exit setup mode. Replace the setup switch
access screw.
3.1Configuration Methods
The 320IS 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 of the optional I/O Module. Configuration
using the menus is described in
Configuration using the EDP port can be accomplished using either the EDP command set described in Section 5.0
on page 36 or Version 3.1 or later of the Revolution® configuration software.
Section 3.3 on page 21.
3.2Configuration Methods
The 320IS indicator can be configured by:
•front panel keys (see section 3.3)
•sending commands or configuration data to the EDP port of the optional I/O Module
Section 3.3 on page 21. When configuration is
Configuration using the EDP port can be accomplished using either the EDP command set described in Section 5.0
on page 44 or the Revolution® configuration software.
3.2.1Revolution Configuration
The Revolution configuration software is the preferred method for configuring the 320IS indicator. Download
Revolution on a computer to set the configuration parameters for the indicator. When Revolution configuration is
complete, configuration data can be downloaded to the indicator through the optional I/O Module’s EDP port.
Revolution supports both uploading and downloading of indicator configuration data. This capability allows
configuration data to be retrieved from one indicator, edited, then downloaded to another.
To use Revolution, do the following:
1. Install Revolution on a computer running Windows® 98 or later. Minimum system requirements are 32MB
of system RAM (64MB for NT4/2000/XP) and at least 40MB of available hard disk space.
2. With both the I/O Module and indicator powered off, connect the PC serial port to the RS-232 pins on the
I/O Module’s EDP port (See Section 8.0 on page 57 for terminal pin diagrams).
3. Power up the I/O Module and the indicator. Use the setup switch to place the indicator in setup mode.
4. Start the Revolution program.
Revolution provides online help for each of its configuration sections. Parameter descriptions provided in this
manual for front panel configuration can also be used when configuring the indicator using Revolution: the
interface is different, but the parameters are the same.
3.2.2EDP Command Configuration
The EDP command set can be used to configure the 320IS indicator using a personal computer, terminal, or remote
keyboard. EDP command configuration sends commands to the indicator EDP port; 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
command set.

Zero range — Selects the range within which the scale can be zeroed. The 1.9% selection
is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at
standstill to zero the scale. Use 1.9% for legal-for-trade applications.
Motion band — Sets the level, in display divisions, at which scale motion is detected. If
motion is not detected for one second or more, the standstill symbol lights. Some
operations, including print, tare, and zero, require the scale to be at standstill. Maximum
legal value varies depending on local regulations.
If OFF is selected, ZTRKBN should also be set to OFF.
Overload — Determines the point at which the display blanks and an out-of-range error
message is displayed. Maximum legal value varies depending on local regulations.
Sample rate — Selects the analog to digital measurement rate of converted samples per
second. Lower sample rate values provide greater signal noise immunity. If instability
occurs, use lower sample rate to reduce signal noise.
Digital filtering — Selects the digital filtering rate used to reduce the effects of mechanical
vibration from the immediate area of the scale. A higher number gives a more accurate
display by minimizing the effect of a few noisy readings, but slows down the settling rate of
the indicator.

Power up mode. In GO mode, the indicator goes into operation immediately after a brief power
up display test.
In DELAY mode, the indicator performs a power up display test, then enters a 30–second
warm up period. If no motion is detected during the warm up period, the indicator becomes
operational when the warm up period ends; if motion is detected, the delay timer is reset and
the warm up period is repeated.
Specifies whether operator has access to piece count mode and the default sample size used
for parts counting. See Level three submenu for parameter descriptions.
Regulatory mode. Specifies the regulatory agency having jurisdiction over the scale site.
• OIML, NTEP, and CANADA modes allow a tare to be acquired at any weight greater than
zero. NONE allows tares to be acquired at any weight value.
• OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is at
no load. NONE allows tares to be cleared at any weight value.
• NTEP and OIML modes allow a new tare to be acquired even if a tare is already present.
In CANADA mode, the previous tare must be cleared before a new tare can be acquired.
• NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net
mode as long as the current weight is within the specified ZRANGE. In OIML mode, the
scale must be in gross mode before it can be zeroed; pressing the ZERO key in net mode
clears the tare.
Consecutive numbering. Allows sequential numbering for print operations. The consecutive
number value is incremented following each print operation.
The initial value of this parameter is set to the start up value specified on the CONSTU
parameter. Changing either CONSTU or CONSNU immediately resets the consecutive number
used for printing.
Consecutive number start up value in the range of 000000–999999. Specifies the initial
consecutive number (CONSNU) value used when the indicator is powered on.

5.0EDP Commands
Note
The 320IS indicator can be controlled by a personal computer or remote keyboard connected to the I/O Module’s
EDP port. Control is provided by a set of EDP commands that can simulate front panel key press functions, display
and change setup parameters, and perform reporting functions. The EDP port provides the capability to print
configuration data or to save that data to an attached personal computer. This section describes the EDP command
set and procedures for saving and transferring data using the EDP port.
5.1The EDP Command Set
The EDP command set can be divided into five groups: key press commands, reporting commands, the
RESETCONFIGURATION special function command, parameter setting commands, and transmit weight data
commands.
When the indicator processes an EDP command, it responds with the message OK. The OK response verifies that the
command was received and has been executed. If the command is unrecognized or cannot be executed, the
indicator responds with
The following sections list the commands and command syntax used for each of these groups.
5.1.1Key Press Commands
Key press EDP commands (see Table 5-1) simulate pressing the keys on the front panel of the indicator. Most
commands can be used in both setup and weighing mode. Several of the commands serve as “pseudo” keys,
providing functions that are not represented by a key on the front panel.
For example, to enter a 15-pound tare weight using EDP commands:
Scale must be at zero gross.

5.1.3The RESETCONFIGURATION Command
The RESETCONFIGURATION command can be used to restore all configuration parameters to their default
values. Before issuing this command, the indicator must be placed in test mode (press and hold setup switch until
TEST is displayed).
This command is equivalent to using the DEFLT function on the TEST menu. See Section 7.8 on page 55 for more
information about test mode and using the TEST menu.
All load cell calibration settings are lost when the RESETCONFIGURATION command is run.
5.1.4Parameter Setting Commands
Parameter setting commands allow you to display or change the current value for a particular configuration
parameter See Tables
5-3 through 5-12 for more information on menu parameters.
Current configuration parameter settings can be displayed in either setup mode or normal mode using the following
syntax:
command<ENTER>
Most parameter values can be changed in setup mode only. Use the following command syntax when changing
parameter values:
command=value<ENTER>
where value is a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an
incorrect command or value, the display reads
??. Changes to the parameters are saved as they are entered but
typically do not take effect until you exit setup mode.

5.2Saving and Transferring Data
Note
Note
Note
Saving and transferring data requires the use of an I/O Module.
Connecting a personal computer to the 320IS EDP port allows you to save indicator configuration data to the PC or
to download configuration data from the PC to an indicator. The following sections describe the procedures for
these save and transfer operations.
Saving and transferring data requires the optional I/O module. See Section 8.0 on page 57 for more
information on the I/O module.
5.2.1Saving Indicator Data to a Personal Computer
Configuration data can be saved to a personal computer connected to the EDP port. The PC must be running a
1
communications program such as ProComm Plus
78076) OR, Section 8.0 on page 57, for information about serial communications wiring and EDP port pin
assignments.
When configuring the indicator, ensure that the values set for the BAUD and BITS parameters on the SERIAL
menu match the baud rate, bits, and parity settings configured for the serial port on the PC. Set the PRNDES
parameter to EDP.
To save all configuration data, place the indicator in setup mode and send the DUMPALL EDP command to the
indicator. The
5.2.2Downloading Configuration Data from PC to Indicator
320IS responds by sending all configuration parameters to the PC as ASCII-formatted text.
Configuration data saved on a PC or floppy disk can be downloaded from the PC to an indicator. This procedure is
useful when a number of indicators with similar configurations are set up or when an indicator is replaced.
To download configuration data, connect the PC to the EDP port as described in Section 5.2.1. Place the indicator
in setup mode and use the PC communications software to send the saved configuration data to the indicator. When
transfer is complete, calibrate the indicator as described in
Calibration settings are included in the configuration data downloaded to the indicator.
If the receiving indicator is a direct replacement for another 320IS and the attached scale is not changed,
recalibration is not required.

6.0Print Formatting
The 320IS provides four print formats, GFMT, NFMT, and CFMT that determine the format of the printed output
when the
acquired, NFMT is used; otherwise, GFMT is used.
Each print format can be customized to include up to 300 characters of information, such as company name and
address, on printed tickets. You can use the indicator front panel (PFORMT menu), EDP commands, or the
Revolution
6.1Print Formatting Commands
Table 6-1 lists commands you can use to format the gross and net print formats. Commands included in the format
strings must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on
the ticket. Text characters can include any ASCII character that can be printed by the output device.

Table 6-1. Print Format Commands
The default GFMT and NFMT print formats use only the new line (<NL>) command and the commands for gross,
net, and tare weights in displayed units (<G>, <N>, and <T>).
The default 320IS print formats are shown in Table 6-2:
NOTE: In OIML and CANADA modes, the letters PT
(preset tare) are automatically inserted after the printed
tare weight.
Table 6-2. GFMT and NFMT Formats
The <G2>, <N2>, and <T2> commands listed in Tab le 6-1 print the gross, net, and tare weights in non-displayed units—
that is, in the units not currently displayed on the indicator.
ID numbers included in the print format string (<UID> command) must be set using the UID=VAL EDP command.
The 300-character limit of each print format string includes the output field length of the print formatting commands, not
the command length. For example, if the indicator is configured to show a decimal point, the <G> command generates an
output field of 13 characters: the 10-character weight value (including decimal point), one space, and a two-digit units
identifier.
6.2Customizing Print Formats
The following sections describe procedures for customizing the GFMT, NFMT and formats using the EDP port, the
front panel (PFORMT menu), and the Revolution® configuration utility.
6.2.1Using the EDP Port
With a personal computer, terminal, or remote keyboard attached to the I/O Module EDP port, you can use the EDP
command set to customize the print format strings.
To view the current setting of a format string, type the name of the string (GFMT or NFMT) and press ENTER. For
example, to check the current configuration of the GFMT format, type GFMT and press
ENTER. The indicator
responds by sending the current configuration for the gross format:
GFMT=<G> GROSS<NL>
To change the format, use the GFMT or NFMT EDP command followed by an equals sign (=) and the modified
print format string. For example, to add the name and address of a company to the gross format, you could send the
following EDP command:
GFMT=FINE TRANSFER CO<NL>32400 WEST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>
A ticket printed using this format might look like the following:
FINE TRANSFER CO
32400 WEST HIGHWAY ROAD
SMALLTOWN
1345 LB GROSS
6.2.2Using the Front Panel
If you have no access to equipment for communication through the EDP port or are working at a site where such
equipment cannot be used, you can use the PFORMT menu (see
Figure 6-1 on page 45) to customize the print
formats.
Using the PFORMT menu, you can edit the print format strings by changing the decimal values of the ASCII
characters in the format string.
Lowercase letters and some special characters cannot be displayed on the 320IS front panel (see the ASCII
character chart on Ta bl e 7-5 on page 49 and Ta bl e 7-7 on page 50) and are shown as blanks. The 320IS can
send or receive any ASCII character; the character printed depends on the particular ASCII character set
implemented for the receiving device.

6.2.3Using Revolution®
The Revolution configuration utility provides a print formatting grid with a tool bar. The grid allows you to
construct the print format without the formatting commands (<NL> and <SP>) required by the front panel or EDP
command methods. Using Revolution, you can type text directly into the grid, then select weight value fields from
the tool bar and place them where you want them to appear on the printed ticket.

recurs.
Table 7-1. 320IS Error Messages
7.1.2Using the XE EDP Command
The XE EDP command can be used to remotely query the 320IS for the error conditions shown on the front panel.
The XE command returns two 5-digit numbers in the format:
xxxxx yyyyy
where xxxxx contains a decimal representation of any existing error conditions as described in Tab le 7-2.
If more than one error condition exists, the number returned is the sum of the values representing the error
conditions. For example, if the XE command returns the number 1040, this value represents the sum of an A/D
reference error (1024) and an A/D calibration checksum error (16).
The second number returned (yyyyy) uses the same bit assignments as shown in Table 7-2 to indicate whether the
test for the error condition was run. For example, the value yyyyy = 63487 represents the decimal equivalent of the
binary value 1111 0111 1111 1111. Using the bit assignments in

7.2Status Messages
Two EDP commands, P and ZZ, can be used to provide status about the indicator. These commands are described
in the following sections.
7.2.1Using the P EDP Command
The P EDP command returns the current displayed weight value to the EDP port, along with the units identifier. If
the indicator is in an underrange or overload condition, the weight value is replaced with ^^^^^^ (overload) or
_ _ _ _
(under range).
7.2.2Using the ZZ EDP Command
The ZZ EDP command can be used to remotely query which annunciators are currently displayed on the indicator
front panel. The ZZ command returns the currently displayed weight and a decimal number representing the LED
annunciators currently lit. The format of the returned data is;
wwwwww uu zzz
where wwwwww uu is the current displayed weight and units, zzz is the annunciator status value (see Table 7-3). If
more than one annunciator is lit, the second number returned is the sum of the values representing the active
annunciators.

7.4ASCII Character Chart
Use the decimal values for ASCII characters listed in Tables 7-5 and 7-7 when specifying print format strings on
the 320IS PFORMT menu. The actual character printed depends on the character mapping used by the output
device.
The 320IS connected to an I/O Module can send or receive any ASCII character value (decimal 0–255), but the
indicator display is limited to numbers, upper-case, unaccented letters, and a few special characters.
The 320IS has the capability to mathematically convert a weight into many different types of units and instantly
display those results with a press of the
Secondary units can be specified on the FORMAT menu using the SECNDR parameter, or by using EDP
commands.
•SEC.MULT only applies if UNITS parameter (SECNDR) is set to NONE.
•To configure secondary units using the front panel, use Tabl e 7-8 to find the conversion multiplier for the
MULT parameter. For example, if the primary unit is pounds and the secondary unit is short tons, set the
MULT parameter to 0.000500.
You must use the MULT parameter to set the decimal point position. Use the numeric keypad or the LEFT/
keys to select the digit; Use the UP/DOWN keys to increment and decrement (see Figure 3-4 on
RIGHT
page 14). LEFT/RIGHT keys also select decimal placement.
•To configure secondary units using EDP commands, use the Table 7-8 to find the conversion multiplier for
the SEC.MULT command. For example, if the primary unit is pounds and the secondary unit is short tons,
send the EDP command SEC.MULT= 0.0005<CR> to set the multiplier for the secondary units.
•Long tons and grains units listed in Table 7-8 cannot be directly specified as primary or secondary units on
the 320IS indicator. For these or other unlisted units of weight, specify NONE on the UNITS parameter.
Ensure that the secondary decimal point position is set appropriately for the scale capacity in the secondary
units. If the converted value requires more digits than are available, the indicator will display an overflow
message (OVERFL).
For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set to
8888.88, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a conversion factor
of 2000, the secondary units display needs five digits to the left of the decimal point to display the 10000 lb secondary
units value.

The 320IS uses RATTLETRAPTM digital filtering to reduce the effect of vibration on weight readings. Adjustable
threshold and sensitivity functions allow quick settling by suspending filter averaging, allowing the weight reading
to jump to the new value.
7.6.1DFSENS and DFTHRH Parameters
The digital filter can be used to eliminate vibration effects, but heavy filtering also increases settling time. The
DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to temporarily
override filter averaging and improve settling time:
•DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold
(DFTHRH) before digital filtering is suspended.
•DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale
readings (DFSENS) fall outside of this threshold, digital filtering is suspended. Set DFTHRH to NONE to
turn off the filter override.
Figure 7-2 shows the digital filter parameters on the CONFIG menu.
Figure 7-2. Digital Filtering Parameters on the Configuration (CONFIG) Menu
7.6.2Setting the Digital Filter Parameters
Fine-tuning the digital filter greatly improves indicator performance in heavy-vibration environments. Use the
following procedure to determine vibration effects on the scale and optimize the digital filtering configuration.
1. In setup mode, set the digital filter to 1. Set DFTHRH to NONE. Return indicator to normal mode.
2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration
effects on the scale. Record the weight below which all but a few readings fall. This value is used to
calculate the DFTHRH parameter value in Step 4.
For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional
spikes to 75 lb, record 50 lb as the threshold weight value.
3. Place the indicator in setup mode and set the digital filter (DIGFLT) to eliminate the vibration effects on
the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective value for
the digital filter.
4. Calculate the DFTHRH parameter value by converting the weight value recorded in Step 2 to display
divisions:
threshold_weight_value / DSPDIV
In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5D: 50 / 5D
= 10.
DFTHRH should be set to 10DD for this example. See Figure 3-2 on page 24 for more information
on display divisions.
5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically
caused by lower vibration frequencies) cause more consecutive out-of-band readings, so DFSENS should
be set higher to counter low frequency transients.
Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.

8.4Fiber Optics Assembly
The 320IS is equipped with duplex fiber optic ports for communicating with other devices located in the safe or
hazardous area. It provides electrical isolation and eliminates the use of I/O barriers commonly used in intrinsically
safe systems. The fiber optic wires are plastic; no polishing or further preparation is required. See
page 58 for the location of the fiber optic ports on the 320IS main board.
60320IS Installation Manual
The fiber optic connections between the indicator and the 320IS need to be cross-linked. The optical output
of the indicator should be attached to the input of the320IS , and the indicator’s input to the module’s output.

1. Cut off the ends of the fiber optic cable with a single-edge razor blade or sharp knife. Try to obtain a
precise 90º angle.
2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal
micro-lens.
3. Screw the connector locking nut down to a snug fit, locking the fiber in place.
4. Secure duplex fiber optic cable to wire tie mounting button located on I/O Module circuit board (see
Figure 8-1 on page 58) using wire ties included in parts kit.
Figure 8-4. Fiber Optics Connector
8.5Analog Outputs
The 320IS uses two 16-bit isolated analog output channels with 4-20mA and voltage (0-5V/±5V/0-10V/±10V)
outputs supplied from a DC/DC converter. The output voltage ranges are DIP-switch selectable (see
page 58). Analog output configuration is done via setup mode in the indicator used with the 320IS (see the
applicable indicator installation manual).
The analog output circuitry consists of two identical channels that can be assigned to gross or net weight values.
The analog outputs can be configured to operate as either current or voltage outputs. The voltage output range is
selected by configuring DIP switches SW1 (1-6) for channel 1 and SW2 (1-6) for channel 2 (see
page 58).

Table 8-7. Analog Output Range Configurations
The analog output port is powered by an isolated DC-DC converter. The outputs available on connector CN1 are
listed in
Table 8-8 below. See Figure 8-1 on page 58 for the location of CN1 and DIP switches.
The 320IS has four digital inputs that can be used to control pre-defined operations in the indicator. Table 8-9
outlines the various functions for the digital inputs.
Digital inputs are available on connector CN4 (see Figure 8-1 on page 58). All inputs are individually isolated via
optocouplers. Table 8-9 outlines the pin connections for CN4.
The digital inputs are designed to receive 0-24V/TTL signals on the incoming lines. Care should be taken to apply
the right DC polarity. Pins 9 and 10 (+5V and DGND) can be used to supply power to the digital inputs. Maximum
current draw should not exceed 0.25A.
See the applicable indicator installation manual for information on checking current digital input states.
8.7Relay Contact Outputs
The 320IS features four relay contact outputs, which default to open. This allows switching of maximum +30VDC,
5A or 250VAC, 5A for each of the four digital channels.
The relay contact outputs are controlled by user-configurable setpoints. The setpoint values and operating
parameters can be defined in the SETPNT menu of the host indicator. See the indicator installation manual for
information on configuring setpoints.
Table 8-10 show pin connections for CN5 of the 320IS board.
The states of the relay contacts are indicated by LEDs LD1–LD4 (see Figure 8-1 on page 58). When an LED is lit,
the contacts of the corresponding relay are closed. See the applicable indicator installation manual for information
on checking relay contact functionality.
