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,

AC100V ~ 240V 50/60HZ.

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

Features

120S has a wide range of applications from batching to simple weighing.

Features:

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

Key in the signal voltage value (mV / V) directly via the keypad, no need to apply

any weight to the bottom work to calibrate the weigher

Display load cell output voltage (mV / V) for future maintenance

Adjustable filter

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 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.
