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 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

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

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.

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.

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.

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.

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.










Service & Troubleshooting

How can field service help?

With all of today’s technology, VEGA Field Service can support you remotely just as well as we can in the office. Please consider using TeamViewer on our website to let us assist you with your setup/troubleshooting needs in PACTware. Email a photo of the setup to to help us get a visual idea of how the equipment is installed and what the vessel looks like. If all you have is a PLICSCOM, we can even use Facetime to help.

Let VEGA field service take control

Did you know you have field service experts at your fingertips with a click of a button? Downloading TeamViewer from allows users to give a secure ID number and password to a VEGA field service agent who can then see and navigate the user’s screen to troubleshoot a problem.

TeamViewer Quick Support App

If PACTware is unavailable, and you’re connecting to a sensor with the VEGA Tools App, VEGA field service experts can provide remote support using the TeamViewer Quick Support App. This will allow a field service expert to view your phone and guide you through the troubleshooting process.
