2. INTRODUCTION
This manual describes how the SW Series Super Wash Down Scales work and how to
get the most out of them in terms of performance. Please read this manual completely
before using the scale.
3. FEATURES
The SW Series Super Wash Down Scales have the following features:
Dust-tight and water-tight construction, complying with IP69K.
The weighing platforms and weighing pans are made of stainless steel (SUS304).
The weighing platforms are designed for easy cleaning and not to collect dust.
Three sizes of weighing platform are available.
Employing touch-sensitive switches enabled the display to be covered with a plastic
sheet, resulting in better dust-tight and water-tight performance.
When a switch is touched, the corresponding LED, above that switch, turns on to
indicated that the switch has been touched.
A bright LED display, with a broad viewing angle.
Three types of weight display resolution are available to cover various applications,
1/3,000, 1/6,000 (1/7,500 for some models) and 1/12,000 (or 1/15,000 for some
models). (To be selected in the function settings.)
The counting mode easily counts the number of objects of the same weight.
The comparator mode compares the displayed value (weight value) with the
previously set comparator values and indicates the results by the large and bright
LED display. Five-level and three-level comparators are available.
The optional comparator relay output (OP-03) can output the results as a relay
signal.
Available weighing units are kg (kilogram), g (gram), Ib (pound), oz (ounce), Ib-oz
(pound and ounce) and pcs (pieces for the counting mode).
The optional RS-232C serial interface (OP-03) or optional RS-422/485 serial
interface (OP-04) can transmit the weight value to a printer or personal computer.
The optional sealed lead acid (SAL) battery (OP-02) can be installed, allowing the
scale to be used where an AC power source is not available.

At level 3, prepare to recharge the battery.
At level 4, recharge the battery immediately. (Refer to “13.1. Using the OP-02
SLA battery”.)
After the weight value internally becomes stable, the display turns off for a moment,
and then, zero is displayed along with the ZERO indicator (power-on zero).
If the weight value is unstable, “------” is displayed. Check if anything touches
the weighing pan, or if there is a strong draft or vibration. Eliminate the cause of the
error.
The range for power-on zero is within ±50% of the weighing capacity (kg) around
the calibrated zero point.
If the power is turned ON while there is a load beyond this range, “------” is
displayed. Remove the load from the weighing pan.
If the scale is to be turned ON with some item loaded, performing a zero calibration
with the item loaded will allow the scale to turn ON that way. (Refer to “11.

10. COMPARATOR
Five-level and three-level comparators are available.
The five-level comparator mode uses four comparator values to compare the weight
value and outputs results in five levels of LOLO, LO, OK, HI and HIHI.
The three-level comparator mode uses two comparator values (upper and lower limit
values) to compare the weight value and outputs results in three levels of LO, OK and HI.
The results are output using LEDs (yellow / green / red).
When the optional comparator relay output (OP-03) is installed, the results are output as
a relay signal.
To use the comparator modes, the function settings “Cp-l” and “Cp” must be
specified.
Using the function setting “Cp-l”, select a comparator mode.

13. OPTIONS
13.1. Using the OP-02 SLA battery
The scale can be operated with a sealed lead acid (SLA) battery, available as an
option.
The scale (with no other options) can be operated continuously for about 90 hours
with a fully charged battery.
The battery will take about 15 hours to be fully charged.
The battery life will vary depending on how the scale is used, the ambient temperature
and so on.
A battery, NP4-6 (6V, 4Ah), manufactured by YUASA, is commercially available.
Caution
• There will be risk of leakage, fire or explosion if the battery is connected
improperly or replaced with the incorrect type.
• Dispose of a used battery according to the local laws and regulations.
• Do not handle the battery with wet hands. Take much care not to get the battery wet.
• Do not install the battery under high temperatures and high humidity.

1. Disconnect the AC power cable from the electrical outlet.
2. Loosen the M4 screws and remove the rear cover of the display.
Note: Take care not to drop the display.
3. Connect the wires inside the display to the battery with much care so that nothing
touches the switches.
Note: Be sure to connect the RED wire to the positive (+ / RED) terminal and
the BLACK wire to the negative (- / BLACK) terminal. Or there is a risk
of explosion.
4. Install the battery into the display.
5. Attach the rear cover to the display and secure it with the screws loosened at step 2.
6. Connect the AC power cable to the electrical outlet.
7. Press the ON/OFF switch and check that the scale turns ON.
8. Disconnect the AC power cable and check that the scale works normally.
13.1.2. Charging the battery
When the weight display shows “lb” (Low battery), the battery voltage is low and
should be recharged. Turn the scale OFF and connect the AC power cable to an
electrical outlet. The charging process will start.
Charging will be performed when the AC power cable is connected to an electrical
outlet and the scale is turned OFF. If the scale is turned ON, trickle charging will be
performed.
The scale can be used while the battery is charging. After fully charged, the scale
will change the charging process to trickle charge automatically.
Notes
• Charge the battery at a temperature between 0°C (32°F) and 40°C (104°F),
preferably, at a range of 5°C (41°F) to 35°C (95°F) .
• Charge the battery when using for the first time.
• The battery must be recharged regularly, every 3 to 6 months, if the scale is
not used for a long period of time. More frequent recharging is required in a
warmer area.

Data format
The data format for the RS-422/485 is the same as the RS-232C except the following:
When used with the function setting “5if 1” (RS-422) or “5if 2” (RS-485), set a
different address to each scale using the function setting “adr##”. ((##=01 to 99)
Start all commands with “@##” (## is the address of the scale to send a command).
All replies from the scale start with “@##”.
The format after “@##” is the same as the RS-232C, both in commands and replies.
When used with the RS-485 interface (function setting: “5if 2”), note the following:
• When sending commands continuously, leave an interval of 500 ms or more
between commands.
• Do not use stream mode (function setting: “prt 0”) when sending commands.
Commands will not be received correctly and will be invalid.
