SAFETY INSTRUCTIONS

Please read carefully the enclosed safety instructions and observe them!

Installation,alloperationalinterventions,maintenanceandservicemustbeperformedbyaqualifiedpersonnel

and in accordance with the attached information and safety regulations. The manufacturer is not liable for

damage caused by improper installation, configuration, maintenance, and service.

The recorder must be installed according to the respective application. Incorrect installation can cause a

malfunction, which can result in damage or accident.

The recorder uses dangerous voltages that can cause a fatal accident. Before you start solving problems

(e.g. in case of failure or disassembly), the device must be disconnected from the power supply. For safety

information the EN - + A standard must be observed.

When removing or inserting a card, observe the safety instructions and follow the recommended procedure.

During any intervention the recorder must be disconnected from the power supply.

Do not attempt to repair or modify the device. A defective recorder must be sent for repair to the manufacturer.

These devices should be safeguarded by isolated or common fuses (breakers)!

The recorder is not designed for installation in potentially explosive surroundings (Ex). Use it only outside

potentially explosive surroundings

INSTRUMENT DESCRIPTION.

2.1 DESCRIPTION

Model OM BCD is a -digit panel monitor of serial or parallel BCD/BIN signal and montor of active transformer tapping leads,

allowing for projection of transitional status and servomotor running.

The instrument is based on a single-chip microprocessor, which guarantees accuracy, stability and easy control.

PROGRAMMABLE PROJECTION

Setting: in „CM“ you can set the type of BCD input or montor of active transformer tapping leads

Projection: -…

Control

The instrument is set and controlled by five control keys located on the front panel. All programmable settings of the instrument

are realised in two adjusting modes:

Configuration menu (hereinafter referred to as „CM“) is protected by an optional numeric code

and containis complete instrument setting

User menu may contain arbitrary programming setting defined in CM with another selective restriction change

All programmable parameters are stored in the EEPROM memory (they hold even after the instrument is switched off).

Excitation

is suitable for supplying power to sensors and transmitters. It has a galvanic separation.

Comparators

are assigned to monitor one, two, three or four limit values with relay output. The limits have adjustable hysteresis

within the full range of the display as well as selectable delay of the switch-on in the range of ..., s. Reaching the preset

limits is signalled by LED and simultaneously by the switch-on of the relevant relay.

Data outputs are for their rate and accuracy suitable for transmission of measured data for further projection or directly into

the control systems. We offer isolated RS andRS with the ASCII protocol or MessBus.

Analog outputs will find their place in applications where further evaluating or processing of measured data in external devices

is required. We offer universal analog output with the option of selection of the output type - voltage/current. The analog output

value corresponds with the displayed data and its type and range are selectable in the programming mode.

. INSTRUMENT CONECTION

The instrument supply leads should not be in proximity of the incoming low-potential signals.

Contactors, motors with larger input power should not be in proximity of the instrument.

The leads into the instrument input (measured quantity) should be in sufficient distance from all power leads andappliances.

Provided this cannot be secured it is necessary to use shielded leads with connection to ground (bracket E).

The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by the above

mentioned principles.

Relay parameters specified in the technical data

apply for resistance load. Upon connection of the

induction load we recommend to fit the leads to relay

 A with a fuse for maximum load protection.

Grounding on terminal „E“ must be connected

at all times
