Special Notice

The indicator is IP68 waterproof design. Only the cables with ψ4~ψ7mm calibre could

be used or will affect the waterproof design. In some certain conditions, the stainless case of

indicator would be opened to set up the load cell, to connect the power cable, or to change the

new rechargeable battery. Before open the stainless case, please make sure the indicator is dry,

if necessary the liquid should be wiped off. The assembling notice should be accurately followed

to assure the waterproof performance. We also strongly suggest that these procedures should

be operated by the technical staff of your supplier.

ASSEMBLING NOTICE:

After the desired steps are done, screw the case with 12 kgf-cm in the following orders.

Do not screw tightly before all screws are in the positions.

Screwing orders:

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. NOTE: There

are no user serviceable parts inside.

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 ~ AC240V.

The operating ambient temperature range is -10oC ~ +40oC.

(+14°F ~ +104°F)

The indicator is IP68 waterproof design. Only the cables with ψ4~ψ7mm calibre could

be used or will affect the waterproof design.

Features

P-120S is an IP68 waterproof weighing indicator and has a wide range of applications from

batching to simple weighing.

Features:

Sturdy and durable stainless steel waterproof and dustproof IP68 design

Stainless steel IP 68 Waterproof design

The stainless steel body can be easily mounted on the control panel.

High performance A/D interface

016 VD sensitivity

Maximum sampling speed of 120 times/second

Measurement range -0.1~ 4.0 mV/V

Flexible Calibration Method

Regular 2-points weight calibration

5-points linear calibration

Key in the signal voltage value (mV/V) directly via the keyboard, no need to apply any

weight to the bottomwork to calibrate the weigher.

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

Adjustable digital filter

Can effectively suppress vibrations generated by the on-site environment

Six weight comparison modes cover most application situations

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

RS232C bi-directional and current loop one way serial interface

Built in MODBUS

The body is made of stainless steel and can be easily mounted on the control panel.

Interface options:

OP-01 RS422/485/232 serial interface

OP-03 16 Bit Analogue current/voltage output interface (4 ~ 20 mA/ 0 ~ 10V)

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

OP-05 Control I/O (8In / 8Out)

1-2 Keyboard 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.

In the normal mode, it performs as Zero operation.

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

In the normal mode, it performs a Gross/Net switch operation.

In the normal mode, it performs as Tare operation.

When parameter setting, it move flashing to right.

In the normal mode, it accesses the FNC-06 setting.
