PLATINUMTM Series Meters Quick Start Guide

Introduction
1. Introduction
This PLATINUMTM Series Meters Quick Start Guide provides only a brief overview of each controller’s
functions and quick configurations to get started. Please refer to the PLATINUMTM Series Meters User’s
Guide PDF at Omega.com/manuals for complete information and specifications for each end device.
1.1 Description
The PLATINUMTM Series meter offers unparalleled flexibility in process measurement. While the meter is
extremely powerful and versatile, great care has gone into designing a product that is easy to set up and
use. Automatic hardware configuration recognition eliminates the need for jumpers. The PLATINUMTM
Series meter displays only the menu items associated with the system’s custom configuration.
Each unit allows the user to select the input type from 9 thermocouple types (J, K, T, E, R, S, B, C, and N),
Pt RTDs (100, 500, or 1000 Ω, with a 385, 392, or 3916 curve), thermistors (2250 Ω, 5K Ω, and 10K Ω), DC
voltage, or DC current. The analog voltage inputs may be single ended bipolar, differential absolute or
differential ratiometric and both voltage and current are fully scalable using a single point or 10-point
linearization to virtually all engineering units with a selectable decimal point that is perfect for use with
pressure, flow, or other process inputs. Multiple Alarms can be configured for above, below, hi/lo, and
band triggering using either absolute or deviation Alarm trigger points.
The PLATINUMTM Series meter features a large, three-color, programmable display with the capability to
change color every time the Alarm is triggered. Various configurations of mechanical relay, SSR, DC
pulse, and isolated or non-isolated analog voltage or current outputs are available. Every unit comes
standard with USB communications for firmware updates, configuration management, and data
transfer. Optional Ethernet and RS-232 / RS-485 Serial communications are also available. The Analog
Output is fully scalable and may be configured for retransmission to follow your input signal. The
universal power supply accepts 90–240 Vac. The low-voltage power option accepts 24 Vac or 12–36 Vdc.
Additional features usually found only on more expensive meters make these the most powerful
products in their class. Some additional standard features are High-high/Low-low Alarm functionality,
external latch reset, configuration save and transfer, and configuration password protection.

Safety Considerations
2. Safety Considerations
This device is marked with the international caution symbol. It is important to read this manual before
installing or commissioning this device as it contains important information relating to Safety and EMC
(Electromagnetic Compatibility).
This instrument is a panel mount device protected in accordance with 2014/35/EU, electrical safety
requirements for electrical equipment for measurement, control, and laboratory use. Installation of this
instrument should be done by qualified personnel.
In order to ensure safe operation, the following instructions must be followed and warnings
observed:
This instrument has no power-on switch. An external switch or circuit-breaker must be included in the
building installation as a disconnecting device. It must be marked to indicate this function, and it must
be in close proximity to the equipment within easy reach of the operator. The switch or circuit-breaker
must comply with the relevant requirements of IEC 947–1 and IEC 947-3 (International Electro technical
Commission). The switch must not be incorporated in the main supply cord.
Furthermore, to provide protection against excessive energy being drawn from the main supply in case
of a fault in the equipment, an overcurrent protection device must be installed.
Do not exceed the voltage rating on the label located on the top of the instrument housing.
Always disconnect the power before changing the signal and power connections.
Do not use this instrument on a work bench without its case for safety reasons.
Do not operate this instrument in flammable or explosive atmospheres.
Do not expose this instrument to rain or moisture.
Unit mounting should allow for adequate ventilation to ensure that the instrument does not
exceed the operating temperature rating.
Use electrical wires with adequate size to handle mechanical strain and power requirements.
Install this instrument without exposing the bare wire outside the connector to minimize
electrical shock hazards.
EMC Considerations
Whenever EMC is an issue, always use shielded cables.
Never run signal and power wires in the same conduit.
Use signal wire connections with twisted-pair cables.
Install Ferrite Beads on signal wires close to the instrument if EMC problems persist.
Failure to follow all instructions and warnings is at your own risk and may result in property
damage, bodily injury and/or death. Omega Engineering is not responsible for any damages
or loss arising or resulting from any failure to follow any and all instructions or observe any
and all warnings.

Caution: Do not connect power to your device until you have completed all input
and output connections. Failure to do so may result in injury!
Use Copper Conductors only
(rated for 75
C min.)
for Power Connections
3.2 Connecting Power
Connect the main power connections to pins 7 and 8 of the 8-pin power / output connector as shown in
Figure 3.
Figure 3 –Main Power Connections
For the low-voltage power option, maintain the same degree of protection as the standard high-
voltage input power units (90–240 Vac) by using a Safety Agency Approved DC or AC source with
the same Overvoltage Category and pollution degree as the standard AC unit (90–300 Vac).
The Safety European Standard 2014/35/EU for measurement, control, and laboratory equipment
requires that fuses must be specified based on IEC127. This standard specifies the letter code “T”
for a Time-lag fuse.

3.3 Connecting Inputs
The 10-pin input connector assignments are summarized in Table 1. Table 2 summarizes the universal
input pin assignments for different sensor inputs. All sensor selections are firmware-controlled and no
jumper settings are required when switching from one type of sensor to another. Figure 4 provides
more detail for connecting RTD sensors. Figure 5 shows the connection scheme for process current
input with either internal or external excitation.

4.1 Description of Button Actions
The UP button moves up a level in the menu structure. Pressing and holding the UP
button navigates to the top level of any menu (oPER, PRoG, or INIt). This can useful if
you get lost in the menu structure.
The LEFT button moves across a set of menu choices at a given level (up in the Section 4
menu structure tables). When changing numerical settings, press the LEFT button to
make the next digit (one digit to the left) active.
The RIGHT button across a set of menu choices at a given level (down in the Section 4
menu structure tables. The RIGHT button also scrolls numerical values up with overflow
to 0 for the flashing digit selected.
The ENTER button selects a menu item and goes down a level, or it enters a numerical
value or parameter choice.
4.2 Menu Structure
The menu structure of the PLATINUMTM Series is divided into 3 main Level 1 groups, which are
Initialization, Programming, and Operating. They are described in Section 4.3. The complete menu
structure for levels 2-8 for each of the three Level 1 groups is detailed in Section 5.1, 5.2, and 5.3.
Levels 2 through 8 represent sequentially deeper levels of navigation. Values with a dark box around
them are default values or submenu entry points. Blank lines indicate user-provided information. Some
menu items include links to reference information elsewhere in this user manual. The information in the
Notes column defines each menu choice.
