VEGA Field Service Pro Tips & FAQs

VEGA field service experts have a wealth of knowledge and experience when it comes to maintaining VEGA sensors. Here are some tips, tricks, and FAQs from our field service team to help you set up and install your VEGA instruments. Use the navigation on this page to check out tips within each topic.
Guided Wave Radar

VEGA Radar Sensors

What can be done to enhance the false signal supression?
During a radar setup, manual edits can be used to enhance the false signal suppression. However, manual edits do not replace the false signal suppression.
What are the Golden Rules of Radar?

The four golden rules for a successful radar setup are:

1) Installation

2) Application

3) Adjustments

4) False Signal Suppression

Can you mount sensors side-by-side?
Mounting sensors side-by-side on a vessel will not affect or interfere with each other's measurements. Each sensor has a unique signature that prevents cross talk with other instruments, meaning you can have a reliable, redundant measurement.
Radar accuracy

Radar level measurement accuracy fully depends on providing the correct vessel measurements. Distance A and B set the 4…20 mA output, and these should be the exact distance from the radar reference point to the 0% and 100% points.

What makes a successful radar installation?

A reliable radar measurement starts with a successful installation. When you are installing your radar, be sure to consult your manual and pay attention to detail. Making sure the installation and wiring are done correctly from the beginning makes for a trustworthy radar you can count on.

What proves a radar device is outputting an accurate measurement?
Measure the distance from the radar reference point down to the level surface for proof the radar is measuring accurately.
Why does my radar have a yellow protective cap?

All VEGAPULS radar units with an encapsulated antenna are shipped with a yellow protective cap. You must remove the cap prior to installation for proper level measurement. That radar signal can’t read through the protective cap if left on.

VEGA Radiometric Sensors

How can you avoid a linearization error on a ProTrac sensor?
When calibrating a ProTrac sensor, activate the points in your linearization table. Without any points selected, you'll get a linearization error.
Have the error code F114?

When you first open a VEGA ProTrac device from storage, make sure you reset the date and time through PACTware. This is a quick fix for error code F114 and ensures startup goes smoothly.

Radiometric sensor setup best practice

A radiometric continuous level linearization table requires a point for the maximum process value. Without this data point, the sensor will output an F066 error message. If you can’t fill all the way to the maximum process value, you can close the shutter(s) on the source(s) to represent full. Consult your source sizing sheet before doing so to make sure it is close to a 100% delta change application.

What is a good way to troubleshoot a radiometric measurement?
When troubleshooting a radiometric measurement, a good way to determine the level in the vessel is with a handheld survey meter. The comparison between the radiometric reading and the handheld survey meter can assure the radiometric measurement is reading properly or create calibration value.
Wiring the terminals correctly

If you check the power of your ProTrac device with a multi-meter, but the detector still isn’t powering up, don’t assume the detector is bad. We use spring-loaded terminals, and sometimes the wire gets pushed in too far. Instead of clamping down on the copper wiring, it clamps down on the insulation. Once the wire is backed out, and the copper is secured under the spring terminal, power the unit back on to see if the detector comes to life.

VEGA Guided Wave Radars

Cable guide wave radars

With the cable versions of our VEGAFLEX 80 series guided wave radars, make sure the cable is fully extended and taut. Slack in the cable can cause false signals and a measurement error.

Mounting on a nozzle

When installing a cable version VEGAFLEX 81 guided wave radar on a mounting nozzle, make sure the rigid section of the probe is equal to or greater than the length of the nozzle. This is required for an effective false signal suppression, and it prevents the sensor from accidentally contacting the nozzle and giving a false measurement.

Mounting on nonmetallic vessels

When you’re mounting a threaded version of a VEGAFLEX guided wave radar on a nonmetallic vessel, don’t forget to install a metal launch plate. This plate directs all the energy down the probe, prevents signal loss on the beam’s return, and it reduces the signal-to-noise ratio. Instructions for sizing and making the plate are in the manual.

Controllers and Signal Conditioners

When to have a backup for your backup

When does it make sense to have a backup for your backup? When you are connecting multiple instruments to a controller, make sure to save a PACTware project during setup. If you lose your backup or have an issue with a device, you will be able to pull your configuration files to get back up and running in no time.

Saving on wiring with the right controller

If you have several different VEGA sensors in a single area, you can pull all of them into a VEGASCAN 693 using an RS-232 or Ethernet connection. This can save on the amount of wiring while giving you a remote display and a single spot to configure all your instruments.

Do some of the VEGA controllers have an Ethernet output?
Yes, some of our controllers do. This allows customers to view the level measurements via a built-in HTML web page or share the information with VEGA Inventory Software. They can send level data to control and business systems using various #communication protocols. The Ethernet output even allows for remote support of sensors connected to the signal conditioner.
Volumetric outputs
A linearization table is placed in the sensor to provide a volumetric output. However, when the sensor is connected to a controller, the linearization table must be placed in the controller.


The first step for a PLICSCOM with Bluetooth

The PIN for a Bluetooth PLICSCOM must be entered manually into a sensor before it can be accessed with the VEGA tools app.

What sensors can have Bluetooth?

Any VEGA sensor made since 2002 can be adjusted wirelessly up to 80 feet away using a Bluetooth PLICSCOM. This makes setup easier and safer when sensors are in hard-to-reach places or in locations requiring additional safety equipment.

Where is the Bluetooth PIN stored?

A Bluetooth PIN is stored in the sensor, not in the PLICSCOM. Therefore, your PIN remains unchanged when you swap out the PLICSCOM.

Installation & Setup

Horizontal mounting

When mounting point level switches like the VEGASWING on the side of a vessel, the forks should be parallel to product movement to reduce resistance to possible product flow. When measuring adhesive and viscous products, the forks should be vertical to reduce buildup. You can check the position of the tuning fork using the marking on the hexagon when installing it.

When does it make sense to have a back up for your back up?
When you are connecting multiple instruments to a signal conditioner. Make sure to save a PACTware project during set up. Should you lose your back up or have an issue with a device you will be able to pull your configuration files to get back up and running.
Take a picture of your installation

During installation, take an image of your application. That way, if a problem arises in the future you have an easy way to give our field service team a visual without being on-site. As they say, a picture is worth a thousand words.

How can you determine the level echo when multiple echoes appear?
When multiple echoes appear it can be hard to determine the level echo. But no need to fear, we have that covered. Use the snowflake icon to freeze the curve and move the level up or down to reveal the real level echo. The real level echo is the furthest to the left (closest to the sensor) that changed positions.
Watch where you install your instrument

When installing your VEGA device, be aware of your surroundings. Mounting instrumentation next to a heat source near or above the ambient temperature limitations can cause immediate damage or greatly reduce the lifespan of the electronic components.
