1. BASIC REQUIREMENTS AND USER SAFETY

- The manufacturer is not responsible for any damages caused by

inappropriate installation, not maintaining the proper environmental

conditions and using the unit contrary to its assignment.

- Installation should be conducted by qualified personnel . During installation all

available safety requirements should be considered. The fitter is responsible for

executing the installation according to this manual, local safety and EMC

regulations.

- If the device is equipped with PE connector, it should be connected to PE

wire.Otherwise PE wire should be connected to GND connector.

- The unit must be properly set-up, according to the application. Incorrect

configuration can cause defective operation, which can lead to unit damage or an

accident.

- If in the case of a unit malfunction there is a risk of a serious threat to the

safety of people or property additional, independent systems and solutions

to prevent such a threat must be used.

- The unit uses dangerous voltage that can cause a lethal accident. The unit

must be switched off and disconnected from the power supply prior to

starting installation of troubleshooting (in the case of malfunction).

- Neighbouring and connected equipment must meet the appropriate standards

and regulations concerning safety and be equipped with adequate overvoltage

and interference filters.

- Do not attempt to disassemble, repair or modify the unit yourself. The unit

has no user serviceable parts. Defective units must be disconnected and

submitted for repairs at an authorized service centre.

- Do not use the unit in areas threatened with excessive shocks, vibrations, dust,

humidity, corrosive gasses and oils.

- Do not use the unit in areas where there is risk of explosions.

- Do not use the unit in areas with significant temperature variations, exposure to

condensation or ice.

- Do not use the unit in areas exposed to direct sunlight.

- Make sure that the ambient temperature (e.g. inside the control box) does not

exceed the recommended values. In such cases forced cooling of the unit must

be considered (e.g. by using a ventilator).

User manual - METER BDL-457

The unit is designed for operation in an industrial environment and must not

be used in a household environment or similar.

2. GENERAL CHARACTERISTICS

The BLD-457 meter is equipped with one current input (0-20mA), two voltage inputs (0-

10V and 0-150 mV), one RTD input (Pt 100/500/1000) and one TC input (thermocouple: K, S, J,

T, N, R, B, E). Temperature of cold ends is compensated automatically. RTD and TC inputs are

fully linearised. It is allowed to use only one input at the same time. Input ranges are described

in the next chapter. Result is showed on 4-digit LED display.

The device can be equipped with two or four relay (or OC type) outputs. Optionally BLD457

can be equipped with active current output, passive isolated current output or active voltage

output. Device BLD-457 is equipped with RS-485 / Modbus RTU communication interface and

sensor supply output. The meter can be ordered in two power supply versions.

The device has 4 buttons being used for main presets programming. To get high protection

level, the keyboard is mounted under transparent cover. To allowuser to change presets without

opening the cover, an IR sensor is mounted.

Remote controller keyboard is equivalent to the device keyboard (Note, that remote

controller is not a part of the BLD-457 set –it is an additional equipment).

BLD-457 can be used for controlling and regulation of processes need proportional and

threshold control like: temperature processes (heating or cooling), valves controlling or other.

4. DEVICE INSTALLATION

The unit has been designed and manufactured in a way assuring a high level of user safety

and resistance to interference occurring in a typical industrial environment. In order to take full

advantage of these characteristics installation of the unit must be conducted correctly and

according to the local regulations.

- Read the basic safety requirements on page 3prior to starting

the installation.

- Ensure that the power supply network voltage corresponds to

the nominal voltage stated on the unit’s identification label.

- The load must correspond to the requirements listed in the

technical data.

- All installation works must be conducted with a disconnected

power supply.

- Protecting the power supply connections against unauthorized

persons must betaken into consideration.

4.1. UNPACKING

After removing the unit from the protective packaging, check for transportation damage. Any

transportation damage must be immediately reported to the carrier. Also, write down the unit

serial number located on the housing and report the damage to the manufacturer.

Attached with the unit please find:

- user’s manual,

- warranty,

User manual - METER BDL-457

4.2. ASSEMBLY

To install device on the wall, a pinholes should be made. Figure 4.1 presents

dimensions of the device and distances between holes. The back side of the device

has four mounting holes. This part of the case should be mounted to a wall by screws.

Figure 4.1. Device and assembly dimensions of the case

- Disconnect the power supply prior to starting assembly.

- Check the connections are wired correctly prior to switching the unit on.

4.3. CONNECTION METHOD

Caution

- Installation should be conducted by qualified personnel . During

installation allavailable safety requirements should be considered. The fitter is

responsible for executing the installation according to this manual, local safety and

EMC regulations.

- The unit is not equipped with an internal fuse or power supply circuit

breaker.Because of this an external time-delay cut-out fuse with a small nominal

current value must be used (recommended bipolar, max. 2A) and a power supply

circuitbreaker located near the unit. In the case of using a monopolar fuse it must be

mounted on the phase cable (L).

- The power supply network cable diameter must be selected in such

a way that inthe case of a short circuit of the cable from the side of the unit the cable

shall be protected against destruction with an electrical installation fuse.

- Wiring must meet appropriate standards and local regulations and

laws.

- In order to secure against accidental short circuit the connection

cables must beterminated with appropriate insulated cable tips.

- Tighten the clamping screws. The recommended tightening torque

is 0.5 Nm.Loose screws can cause fire or defective operation. Over tightening can

lead to damaging the connections inside the units and breaking the thread.

- In the case of the unit being fitted with separable clamps theyshould

be insertedinto appropriate connectors in the unit, even if they are not used for any

connections.

- Unused terminals (marked as n.c.) must not be used for

connecting anyconnecting cables (e.g. as bridges), because this can cause

damage to the equipment or electric shock.

- If the unit is equipped with housing, covers and sealing to, protecting

againstwater intrusion, pay special attention to their correct tightening or clamping.

In the case of any doubt consider using additional preventive measures (covers,

roofing, seals, etc.). Carelessly executed assembly can increase the risk of electric

shock.

- After the installation is completed do not touch the unit’s connections

when it isswitched on, because it carries the risk of electrical shock.

Due to possible significant interference in industrial installations appropriate measures

assuring correct operation of the unit must be applied. To avoid the unit of improper

indications keep recommendations listed below.

–Avoid running signal cables and transmission cables together with power supply cables and

cables controlling inductive loads (e.g. contactors). Such cables should cross at a right

angle.
