1.6LED Annunciators

The 320IS Plus display uses eight LED annunciators to provide additional information about the value being displayed (see Figure 1-1 on page 3):

	LED Annunciators
Gross	The Gross and Net annunciators are lit to show whether the displayed weight is a
Net	gross or net weight.
Center of Zero	Gross weight is ±0.25 graduations of zero. This annunciator lights when the scale is

0zeroed.

	Standstill				Scale is at standstill or within the specified motion band. Some operations, including
					tare functions and printing, can only be done when the standstill symbol is shown.
					The Tare Acquired light shows that a tare value has been entered.
	Count				The Count annunciator is lit to show that the indicator is in piece count mode.
	0 lb				lb and kg annunciators indicate the units associated with the displayed value:
					lb=pounds, kg=kilograms. Two units of measurement can be chosen to toggle
	0kg
					between.
					The displayed units can also be set to ounces (oz), short tons (tn), metric tons (t),
					grams (g), or they can be disabled. A user-defined unit can also be set as secondary
					unit by declaring a conversion factor in the setup menu. The lb and kg LED’s function
					as primary and secondary units annunciators for some combinations of primary and
					secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the lb
					annunciator is lit for primary units, kg for secondary units.

Table 1-2. LED Annunciators

Table 1-3 shows which annunciators are used for all combinations of configured primary and secondary units. For example:

•If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb LED is lit for primary units, kg for secondary units.

•If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb LED is lit for primary units, kg for secondary units. There is no LED for short tons, so the kg LED is used as the secondary units annunciator.

•If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary units (tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs are used as primary and secondary units annunciators.

See Section 3.2.2 on page 25 for more information about configuring primary and secondary display units.

Figure 2-1. Intrinsically Safe System Diagram

2.3.1Power Supply to Indicator

Do not, under any circumstances, connect or disconnect the DC wire from the indicator while the AC WARNING power is applied to the power supply. This will cause the power supply fuse to blow.

The indicator should be powered by an FM-approved Rice Lake power supply or alternatively from an external battery pack. The power requirements of the 320IS Plus are as follows:

•Minimum input voltage: 5.8 V

•Maximum input voltage: 7.9 V

•Peak current consumption: 190 mA

•Average input current (with four load cells): 140 mA

The DC power cable should be attached to connector CN1 (see Table 2-1). Care must be taken to wire CN1 with the correct DC polarity. See Section 2.4 on page 11 for information on cabling through metal cord grips.

CN1 Pin	Function	Wire Color
1	+ Voltage (5.8 – 7.9 V)	Green
2	Ground (V–, Common)	Brown

Table 2-1. DC Power Supply Connections

10 320IS Plus Installation Manual

A separate conduit system is recommended for installation. The type suggested for this application is 3/4" rigid 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.

2.3.2AC Power Wiring

Standard units are powered by an FM-approved power supply. 100–240 VAC into RLWS IS-EPS-100-240 Intrinsically safe DC output power supply (PN 72713) is recommended.

See the IS-EPS-100-240 Power Supply Instruction Sheet (PN 79820) for information on wiring and power specifications.

2.3.3Battery 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.

Note

Note

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.

Load Cell Size	Quantity of cells	Operating Time
350 load cell	1	40 - 50 hours
	4	35 - 40 hours
700 load cell	1	45 - 55 hours
	4	40 - 50 hours

Table 2-2. Estimated Battery Operating Times

While connected to the DC battery pack with the indicator off, the 320IS still draws a small amount of current that will shorten battery run time. To preserve battery life, disconnect the battery when not in use.

2.4Cable Connections and Installation

The following sections contain information on cable connections and installation for the 320IS Plus.

Intrinsically safe cables are specified by control drawing. All cables must have appropriate internal Note inductance and capacitance. Cable lengths are based on group classifications.

2.5Fiber Optics Installation

The 320IS Plus 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 Plus:

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.

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).

Important	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.

3.0Configuration

To configure the 320IS Plus 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, SETPNT, DIGIN, and ALGOUT functions require fiber optics communications with I/O

Note 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 Section 3.2 on page 22. When configuration is 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 Plus indicator can be configured by:

•front panel keys (see section 3.2)

•sending commands or configuration data to the EDP port of the optional I/O Module

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.

3.1.1Revolution Configuration

The Revolution configuration software is the preferred method for configuring the 320IS Plus 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 61 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.

3.1.2EDP Command Configuration

The EDP command set can be used to configure the 320IS Plus 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 Section 5.0 on page 44 for more information about using the EDP command set.

3.1.3Front Panel Configuration

The 320IS Plus 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.
