Switching points for the position

You can use these parameters to define two position limits for

signaling (see option “Module for digital position feedback”).

Digital output

The alarms generated in the positioner can be polled via the

digital output as a collective alarm.

The desired information can be selected via the operator panel

or remotely via the configuration program.

The output can be set to “active high” or “active low”, as required.

This parameter can be set separately for each end position.

When the respective configured limit value is exceeded, the

shut-off function causes immediate travel of the actuator until

reaching the set end position.

If the value “0” is entered for the corresponding parameter, the

position is further controlled, even in the respective end

position.

Shut-off function

This parameter can be set separately for each end position.

When the respective configured limit value is exceeded, the

shut-off function causes immediate travel of the actuator until

reaching the set end position.

If the value “0” is entered for the corresponding parameter, the

position is further controlled, even in the respective end

position.

Travel time prolongation

This function can be used to increase the max. travel time for

full travel. This time parameter can be set separately for each

direction.

This function can only be used with the pneumatics with the

safety function “fail-safe”.

Switching points for the position

You can use these parameters to define two position limits for

signaling (see option “Module for digital position feedback”).

The positioner has a local communication interface (LCI) as

standard. Additionally, a “HART communication” option for

communication via the 20 mA signal is available. Both

communications are based on the HART Protocol.

Alternatively, HART5 or HART7 are available.

Inputs / Outputs

In addition to its input for the analog position setpoint, the

positioner is equipped with a digital input which can be used

to activate control system functions in the device. A digital

output allows you to output collective alarms or fault messages.

Modular design

The basic model can be enhanced at any time by retrofitting

optional equipment.

Option modules can be installed for analog and digital position feedback.

Additionally, a mechanical position indicator, proximity

switches or 24 V microswitches are available for indicating the

position independently of the mother board function.

Use

The positioner has a built-in operating panel providing a 2-line

LCD display and 4 operating buttons for commissioning,

configuration and monitoring during live operation.

Alternatively, the appropriate configuration program can be

used via the available communication interface.

Data that is accurate

The NGC8106 is a single stream manual calibration device, it

is intended to be calibrated monthly or quarterly, so there is no

need to leave an expensive calibration blend at each GC site.

Easy to use and cost effective

The use of the NGC8106 eliminates many of the problems

associated with composite samplers. There are no sample

transport issues, no analysis costs, no lag in getting the

gas quality information into the gas accounting system and

instant alarming of potential data loss. While the initial cost of

the NGC and its installation may be higher than a composite

sampler. The sampler’s ongoing operation and maintenance

costs make the NGC8106 a viable economic alternative.

Data is difficult to obtain and not cost effective

Shipping requirements and DOT regulations make it

increasingly difficult to ship samples to the central laboratory.

These problems with composite sampler had to be tolerated

because the cost of a GC was too much to put on these lower

volume stations, UNTIL NOW.

Solution: NGC8106

Data that is real-time

ABB is pleased to introduce the NGC8106. Based upon the

industry leading NGC platform, the NGC8106 is a perfect

replacement for composite samplers. The user can now enjoy

real-time data instead of monthly averages, and shipping and

sample collection errors have been virtually eliminated.

Addin a multivariable transmitter and the NGC8106 becomes a

total energy meter. Or utilize the remote communications on

the 8106 to transmit real gas quality data to an existing flow

computer.

Data is not real-time

Typically it takes one month to collect sample before it is sent

to the laboratory for analysis. Although the analysis probably

only takes a week, it could still be another three weeks before

the technician is back at the site to collect the next sample

bottle. By the time the gas quality data is entered into the flow

computer it could be anywhere from 1-2 months old.

Data is not accurate

Although the lab analysis is very accurate it is only as good

as the sample handling practices that were used to obtain the

sample. IF the sample bottle is not properly purged or clean

when it was installed then the analysis data will be corrupted.

The error gets magnified when applied across a whole month

of gas production.

The NGC8106 performs on-site, real-time gas analysis and

heating value computation. The 8106 can be used as a total

energy meter with the addition of a multivariable transmitter!

The NGC8106 is a perfect replacement for automatic

samples. The user will enjoy real-time data instead of monthly

averages, and shipping and handling errors have been virtually

eliminated. The NGC8106 is based upon the industry leading

NGC8206 platform.

NGC8209 mounted in a black case. It is recommended that

the unit be left in an operational mode while transporting.

All the valves, gauges, inlet ports, and PCCU32 (the laptop

driven man-machine interface) connectors are bulkhead

mounted on panel to provide the technician with ready access.
