2.2 Operationn

The instrument is set and controlled by five control keys located on the front panel. All programmable settings of the instru­ment are realized in two adjusting modes:

LIGHT Simple programming menu

- contains only items necessary for instrument setting and is protected by an optional numeral code

PROFI Complete programming menu

- contains complete instrument menu and is protected by an optional numeral code

USER User programmable menu

- may contain arbitrary items selected from programmable menu (LIGHT/PROFI), which determines
the authorization (see or change)

- access is without password

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

Complete operation and setting of the instrument may be performed via communication interface
OM Link, which is a standard equipment of every instrument.

The operation program is freely available (www.orbit.merret.cz) and the only requirement is the
purchase of OML cable for connecting the instrument to PC. It is manufactured in version RS 232 and USB and is compatible
with all ORBIT MERRET instruments.

Another option for connection is with the aid of data output RS 232 or RS 485 (without the need for OML cable).
The OM LINK program version „Standard“ allows you to connect an unlimited number of instruments with the option of

visualizatiion and storage in PC.

2.3 Extension

Excitation is suitable for feeding sensors and converters. It has a galvanic isolation.
Comparators are assigned to control two limit values with relay output. The limits have adjustable hysteresis as well as

selectable delay of the switch-on. 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 an isolated RS232 and RS485 with the ASCII protocol.

Analog outputs will find their place in applications where further evaluating or processing of measured data in external
devices is required. We offer a universal analog output with the option of selection of output type - voltage/current. The value
of analog output corresponds with the displayed data and its type and range are selectable in the programming mode.

Time backup by means of RTC circuit is designed for the „TIMER“ measuring mode and secures time measuring even if the
instrument is switched-off (without display projection).

INSTRUCTIONS FOR USE OM 652UC

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.

Setting initial value

- the function allows the user a single-time
setting of initial value of display projection

- the instrument is preset from manufacture
into “FREQU.” measuring mode and unless
another mode is set the item remains hidden

- if you need to set initial value for another
mode it is necessary to do so upon next
access to programming menu > after

change of measuring mode

- setting “SET V.” is a one-time operation
unlike the “OFFSET” option, i.e. after
resetting the display value is “0”, provided
there is no other value set in the “OFFSET”
item
