Safety

When the instrument is installed, connect an earth bonding conductor from FG to the earth

connection marked “ ”.

Disconnect the mains power supply before opening the instrument housing.

To install the optional interface cards, it is necessary to disconnect the mains power supply

and fit a yellow/green earth bonding cable to the rear panel.

Before turning the power on ensure the supply voltage is within the acceptable range,

AC 90V ~ 240V 50/60HZ.

The operating ambient temperature range is 0 oC ~ 40 oC (32 °F ~ 104 °F).

Features

320S has a wide range of applications from batching to simple weighing.

Features:

DIN size panel size 144x74 mm, convenient to store equipment or on the control panel. The

front panel has water splash protection

0.2μV/d sensitivity, 360 times/s max sampling speed

Application range of - 0.1 ~ 4.0 mV / V

USB Logger (Up to 16GB): weight and time data can be stored in the USB PenDrive

Note: when both USB Logger and RS-485 are used at the same time, scan rate is

recommended to be <1000ms

Note: USB Logger is used without sufficient system resources, the followings might occur:

Use webpage to configure settings for 320S (Default IP address: 192.168.1.210)

Use webpage (I.E 10/11) to update firmware for 320S

Flexible calibration method: standard 2-points calibration, 5-points linear calibration, manually

enters signal voltage in mV / V without actually applying load.

Read load cell output voltage in mV / V for future maintenance use.

Adjustable digital filter: to effectively suppress the vibration generated by the environment.

Six weight comparison modes that can cover most applications

Stand alone batching mode or connect to PLC for external system control

- Built in batching / dosing functions

- Manual / automatic discharge operation

- Set cycle times in a batch

- Totalise weight and number of cycles

Built-in RTC (Real Time Clock)

Build in RS232C bi-directional and RS485 communication

Built in MODBUS

Interface options:

OP-01 RS-422 / RS-485 / RS-232 serial interface

OP-02-1 BCD parallel output interface (Open collector output)

OP-02-2 BCD parallel output interface (TTL output)

OP-03 16 Bit Analogue current/voltage output interface

(4 ~ 20 mA / 0 ~ 10 V)

OP-04 Control I/O (4 In / 4 Out) + Setpoint In (BCD code)

OP-05 Control I/O (8 In / 8 Out)

1-3 Suggestions to control and eliminate electrostatic interference

The industrial environment is prone to interference from the electrostatic field, the following

suggestions to control and eliminate of electrostatic are provided in order to protect the normal

operation of the equipment in this environment,

Use the screw next to the grounding symbol on the back panel of the chassis to wire

connected to the weighing platform, and ensure chassis and platform are shorted.

Please use a wire size ≧AWG18

1-4 Keypad Description

When entering data or reference setting, it means “ESC”.

In the normal operation, it puts the indicator in standby mode or escape.

Entering standby mode: All of the display (except ZERO “” symbol)

and serial data output are disabled.

Escape from standby mode: Re-power on mains for normal operation.

Function FNC-03 can be used to selectively disable individual keys.

Zero operation, will be limited by functions CSP-05 and CSP-10.

Zero operation, will be limited by functions CSP-10 and CSP-11.

When parameter setting, it moves the flashing digit left.

In the normal mode, it performs a Zero operation.

When parameter setting, it moves the flashing digit right.

In the normal mode, it performs a semi-auto Tare operation.

When parameter setting, it increments the flashing digit or steps up the

select item.

In the normal mode, it accesses the FNC-05 setting.

During power-on countdown, press this key to display firmware version.

When parameter setting, it decrements the flashing digit or steps down

the select item.

In the normal mode, it accesses the FNC-04 setting.

Confirm / enter key.
