1 General information

The Se-01 meter is the ready subassembly, designed for single- or double-range balances, using the extensometer force sensors.

The meter is used in few types, differing in housing structure and displays size:

- SE-01/A/18 – OSA aluminium housing, powder coated, displays 18 mm (LED)

or 14 mm (LCD)

- SE-01/N/18 – OSN stainless steel housings, hermetic (IP65), displays 18 mm

(LED) or 14 mm (LCD)

- SE-01/N/25 – ODN stainless steel housing, hermetic (IP65), displays 25 mm

(LED) or 14 mm (LCD)

As a standard, the SE-01/A/18 is a subassembly of platform B series balances, the SE-01/N/18 – of stainless and hermetic balances, the SE-01/N/25 – of platform 4B balances produced by AXIS.

Each meter has the set of special functions: automatic zeroing, pieces counting, comparing with threshold values, etc., which may be available for the user or not – according to the order.

In the further manual part the SE-01 meter operation is described, as the part of complete balance.

2 Certificates

Test certificate of SE-01 indicator (No PL CB 1) was issued by Main Office for Measurements in Warsaw (Notified Body No 1440).

SE-01/N/18(25) indicators are of IP65 protection class, confirmed with the research carried out by The Research Laboratory of The Electrotechnology Institute in Gdańsk, accredited by Polish Centre for Accreditation.

5 Security rules

1. All repairs and necessary regulations can be made by authorized

personnel only.

To avoid electrical shock or damage of a scale or

connected peripheral devices, it is necessary to

follow the security rules below.

2. To avoid fire risk use a feeder of an appropriate type (supplied with a

scale). Pay attention that supply voltage is compatible with specified

technical data.

3. Do not use a scale when its cover is opened.

4. Do not use a scale in explosive conditions.

5. Do not use a scale in high humidity.

6. If a scale seems not to operate properly, plug it out of the mains and do

not use it until checked by authorized service.

service point or use Installation Guide delivered with the indicator.

2. The manufacturer gives a full guaranty for SE-01 indictor only when the

indicator was mounted by AXIS Sp. z o.o. In other cases the guaranty obligation is taken over by the final contractor of the weighing device.

mains to avoid damaging the indicator!

To comply CE marking requirements, for connecting the wires use filtering cores delivered with the indicator, appropriate for signal type: sensor(s) wires – φ20mm core, protecting wires - φ16mm (see the diagram below). The cores should be placed within 30mm from the place of its connection.

In SE-01/A/18 indicator an interface is placed on indicator’s housing. In SE01/N/... indicators interfaces are ends of wires which go out from an indicator.

Attention:

To connect scale’s wire with RS232C interface (described above) to a computer, RS232C adapter should be used which is included as the equipment of SE-01/N/18 and SE-01/N/25 indicators (electric diagram of RS232C adapter is the same as WK-1 wire).

2. In case of using the scanner, the RS232C port is divided into two separate connectors. Receiver and 5V power supply are for the scanner, and transmitter for the computer.

7.2 Transmitter interface

P1-P3 (THRESHOLDS) outputs are used to connect dosing or signaling (option) devices. There are opto-isolators of an open collector type with 100mA / 24V maximum load. They can be connected directly to transmitters inputs or to MS3K/P board offered by AXIS separately or in ST 3K/P control box (3 transmitters, own power supply).

In SE-01/A/18 indicator THRESHOLD interface is placed on indicator’s housing.

Outputs are adapted for direct connect RM96P transmitter of DC24V input voltage

and AC250V 8A output. Transmitter’s coil has to be secured with diode e.g.

1N4148.

It is recommended to use MS 3K/P electronic board (3 transmitters of RM96P

type – max. load of 3A/250V) or complete ST 3K/P control (feeder, 3 transmitters

like above).

The way THRESHOLD outputs work is described in the separate document

(Special functions description).

7.3 External key interfaces

The input of external keys allows to place (make double) selected scale keys into

control box or operator’s workstation. As a standard the input is taken out with a

wire for direct connect to a control panel. SE-01/A/18 indicators can be equipped

with external key interfaces (as an option on demand).

External keys require external 24V DC feeder, which ensure galvanic isolation of

a scale from automatic systems.

8 General Rules

1. After switching-on the power, the scale proceeds with self-tests and zeroing the

scale. During start-up the scale should not be loaded (does not apply to tank scales, where scales are not zeroed after start-up).

2. Before each measurement make sure that zero indicator is displayed. If zero

indicator does not displayed or “----“ communicate appears, press →0← key and wait until zero indication and zero indicator appears.

3. The scale is equipped with a tare equal to its range. To tare the scale press

→T← key. Storing a tare value does not extend measuring range, but only subtracts it from a load placed on a pan. If the scale is not loaded →T← key does not operate – to zero the scale press →0← key.

4. Weighing result should be read when the indicator " " lights, which signalizes

stabilization of a result.

5. Weighed sample should be placed in the centre of the platform.

Do not drop weighed objects on the platform!

Do not overload the scale more then 20% of maximum

load (Max).

6. Protect the scale against dust, aggressive dusts and liquids. To clean it is advised

to wash the scale with water and dry it afterwards.

7. Each indicator may be equipped on demand with a set of special functions:

constant tare, total weight and many more.

9 Indicator cooperation with other systems

Opto-isolators outputs of P1-P3 signals (open collector) are destined for external signaling or dosing devices control. Interface work is controlled by function of comparing with threshold values (tHr).

16 ENGINEERING DOCUMENTATION

_____________________________________________________________________________________________

10 Cooperation with computer or printer

In indicators equipped with one serial RS232C (RS485) interface there are two possible modes of interface work:

Standard mode

The scale sends weighing result when initial signal form computer appears or key of the scale is pressed.

Automatic mode (for cooperation with a printer)

Data is sending automatically after a sample is put on and scale indication becomes stable. Next transmission is possible after sample is taken off. Successive measurement number and weighing result are sending. The choice of serial interface work mode is made by use of LPt special function (see further).

The description of data transmission protocol in standard mode (Long protocol)

A scale sends data with following settings: Communication parameters: 8 bits, 1 stop bit, no parity, baud rate 4800bps.

Available orders and scale responses:  initialising signal (data send order):

Computer→Scale: S I CR LF (53h 49h 0Dh 0Ah), Scale→Computer: scale response according to description below (16 bytes),

 setting high threshold value:

Computer→ Scale: S H D1...DN CR LF (53h 48h D1...DN 0Dh 0Ah), D1...DN – threshold value (see ) Scale →Computer: without response.

Note: Network number different than zero (F..-rS / nr function) changes scale working mode: communication with a computer is possible after logging the scale in with 02h scale_number command. To log the scale out use 03h command.

The description of data transmission protocol in automatic mode

Every time weighing is done in the moment when indications becomes stable the scale sends successive three-digit number (counter value) and result of the weighing. If an indication is zero there is no transmission from the scale. Weighing counter is cleared after each choosing of automatic mode (see further – LPt function).

The sequence of sending values is the following:

18 ENGINEERING DOCUMENTATION

1. Three digits of successive measurement number(digits are sending in order

2. Two space characters separating a number from scale indication.
