Display Brightness

The brightness of an LCD display is the amount

of light emitted and is measured in nits or

candelas per square meter, which has units of

nits or cd/m2. Most commercial desktop

displays have a brightness of 200 to 300 nits. To

see a display in outdoor light requires a

brightness of about 700 nits or greater. Almost

all new LCD displays use some form of white or

RGB LED backlight.

Display Brightness Half-Life

An important characteristic of an LED backlight

is the brightness half-life, which is the time

measured in hours that the brightness output

will decrease by half after running the LED

backlight at full brightness. The decrease in

brightness will not substantially decrease after

the half-life time has elapsed. Most displays

have a half-life of around 50.000 hours (or 5.7

years). Some of the brighter displays can have

a half-life of 20.000 hours or less.

Bright Idea: The brightness life of the display

can be dramaticallyincreased and burn-in can

be mitigated by allowing the screen saver to

dim and/or turn off the display when not in use.

Touchscreen Display Support

Orbit Display uses a touchscreen display. You

can show data from up to twelve Orbit 60

chassis connected via Ethernet on a single

Orbit Display.

If necessary, Bently Nevada can produce

custom drivers for specific displays and

pointing devices. For assistance, or for a list of

supported displays and required drivers,

contact Bently Support at Bently.com/support.

The Orbit Display is backwards compatible  with

the existing 10.4″ and 15″ displays currently

supported by the 3500 system:

Supported Displays

120M8155-01  10.4” 640×480 Hazardous Location Display

102M8950 15” 1024×768 Hazardous Location Display

150M1466  21.5” 1920×1080 Industrial Display

Display Burn-in or Ghosting

All display technologies are susceptible to

burn-in or ghosting, which occurs when static

and cumulative non-uniform pixel use

discolors areas on a screen. Burn-in can be

noticed when the display changes and when

the display is turned off.

Orbit Display

The Orbit Display system includes your choice of display

screen, an industrial computer with a customized operating

system, and software that communicates with one or more

Orbit 60 systems. The system can be certified for hazardous

locations. Condition monitoring data is communicated to

external displays via a Display Port or VGA connection.

Touchscreen connection can use USB or Serial connection.

The Orbit Display shows Orbit 60 machinery protection

system information such as:

• Direct measurements

• 1X measurements

• Gap measurements

• Measurement alarms

• System event list

• Alarm event list

The standard tabs show direct measurements, 1x filtered

vibration measurements, gap values, and other trended

variables.

Expensive KVM Extenders are not needed to place displays far

away from Orbit 60  installation locations. Since the Orbit

Display connects to Orbit 60 chassis via standard Ethernet

network connections, the Orbit 60 Display system can be

placed anywhere your Ethernet network infrastructure

supports. The display location is only limited by security and

network infrastructure necessary to support Orbit Display.

It is possible to place Orbit Display in a variety of locations:

• Physically adjacent to Orbit 60 chassis

• Next to the machines being monitored

• In a local or remote control room

Pairs of relays within the module function as a single Double

Pole, Double-Throw relay when appropriately configured.

Both relay types are available for SIL system implementation.

See Orbit 60 SIL User Guide (134M0398) for additional details

and design considerations.

Electromechanical Relay (EMR)

This relay drives a load directly, or through, an interposing

relay. This module takes two slots. It features 8 Epoxy Sealed,

Single-Pole Double-Throw Electromechanical Relays. This

module supports an AC voltage range of 5-250 Vac for loads

of 100 mA to 4 A. The module also supports DC voltages and

loads of 5-30 Vdc at 4 A.

Solid State Relay (SSR)

This relay connects to an external system’s discrete input for

low current communication. It occupies a single slot and

features 8 Solid-State Relays. This module supports

secondary voltages from 1 Vdc up to 125 Vdc

and loads of 0.01 to 125 mA.

Description

Relay modules may be programed to actuate based on

alarm conditions defined in other modules.  Use standard

logic elements (True AND, Normal AND, OR and NOT) to

combine various alarms and statuses (e.g. OK statuses,

Bypass, Protection State, Inhibit, Attention, Protection Fault,

etc.) into relay activation conditions. Orbit Studio is used to

program the voting logic.

Relays can operate as a  system or group protection fault

relay, if programmed to do so, especially when the protection

fault relay on the SIM does not provide adequate granularity

of system health – typically for multiple machines in one system.

The recorder output module provides analog outputs for any

proportional signal measurements available within the Orbit

60 system including the following examples:

• Processed Vibration measurements (Direct, 1X

Amplitude, 1X Phase, etc.)

• Temperature measurements

• Position measurements

The recorder output channels’ configuration includes several

options for clamp output levels, providing an indication of an

invalid health status of the associated measurement. The

system will also attempt to output the configured clamp

signal when any fault within the Recorder

Output channel or output load is detected.

The configuration also includes the option to

include Recorder Output channels within the

protection path so that detected faults within

the Recorder module or wiring can be

annunciated through Protection Fault relays.

(See SIL User Guide 134M0398 for additional

details when using the Recorder Output channels in a SIL application.)

These differing signal ranges can accommodate

connections to various interfacing equipment designed to

consume and interpret the proportional analog signals.

Description

The recorder output module is a 8-channel single slot width

module that provides an analog output signal based on a

processed measurement from any of the proportional

measurements within  the system. The output of the recorder

output channel is proportional to the associated

measurement value within the measurement’s full scale range.

The recorder output module is software-selectable to

operate in several output modes, providing the following

analog output signal ranges:

• 4 to 20 mA

• 1 to 5 V

• 0 to 10 V

When configured for a 4-20 mA output, the recorder channel

supports the extended output range of 3.8 mA to 20.5 mA to

align with the NAMUR NE43 standard.

These differing signal ranges can accommodate

connections to various interfacing equipment designed to

consume and interpret the proportional analog signals.

Description

The Orbit 60 Series Isolated Process Variable and Discrete

(PVD) Input module processes machine-critical parameters

such as pressure, flow, temperature, and levels that merit

continuous monitoring. The module conditions and digitizes

the signals so the result can be compared with user

programmable alarm setpoints. The user can program the

PVD module using the Orbit Configuration software to

perform current, voltage or discrete input measurements.

This module provides discrete inputs for essential operational

commands, such as Trip Multiply for machine start-up and

Alarm Inhibit.

The monitor accepts +4 to +20 mA current inputs or any

proportional voltage inputs between -10 Vdc and +10 Vdc, in

addition to monitoring “dry” or “wet” contacts which can be a

sensor, switch, or relay.
