Digital cloud-based asset monitoring is offered worldwide

Posted on

Our new digital cloud-based services platform can be used worldwide. The software means Optima can monitor and track your assets in real time. You can view device history, schedule tasks and monitor the machine via the cloud. This keeps you informed of any issues as and when they occur. Escalation thresholds can be configured, so depending on the nature of the fault, the relevant people are emailed. The monitoring system can also give daily reports via email notifications with programmable triggers.

If the machine starts operting in an unexpected way, an email is tiggered, sending messages to your maintenance and response teams We can use the system
to diagnose the issues with your hardware and ship equipment to site to rectify the problem. 

These online diagnostics can be viewed 24/7 and the software can bring to your attention any faulty systems, sometime even before a breakdown happens.

Please contact us for a no-obligation dashboard trial.

Safety Scanner Issues and EN999

Posted on

Optima were recently asked to advise on a safety guarding application for one of our customers. 

There had been a number of false trips of the laser scanner causing the machine to stop. A plastic chain ‘barrier’ had been fitted as a temporary measure with instructions to operators to not breach the barrier whilst the machine was running. 

The customer naturally wanted this rectifying as soon as possible. Optima carried out a service visit to site.

On the site visit, our engineer noted that the scanner was showing a code which indicated that the front screen required cleaning.

 Once the screen was cleaned thoroughly the scanner did not show any faults or errors and was in normal run mode.

 

Further checks on the original software were made to ensure the scanner configuration met the requirements of the safety guarding application. 

The diagrams to the left show the Warning Field configuration (Yellow) and the Protective Field (Red). Both of these were confirmed to be operational. 

The warning field causes the klaxon to operate but does nto stop the machine. The protective field causes an emergency stop of the machine.

We did find some concerns that needed addressing.

1. None of the scanner safety circuit had been documented on any drawings.

2. Non-compliance with EN999 ‘Safety of machinery. This defines the positioning of protective equipment in respect of approach speeds of parts of the human body’. It includes a formula to be used to calculate the distance from a hazard that a safety zone must be triggered. 

Based on the stopping times of the machine, the scanner was placed too close to the machine to be effective in an emergency.

We are working closedly with our customer to assist them with this application and help them achieve a safe and effective solution to this.

If you need any support with safety applications or other upgrades, please get in touch.. 

Parker SSD Microtach Replacements

Posted on

Microtach encoders, manufactured by SSD Drives for many years offered reliable transmission of sensitive high-frequency information in an electrically noisy environment.

The technology used a combination of an incremental encoder disk combined with micro-electronics to facilitate the use of single fibre optic transmission of the encoder pulses.

This gave a huge advantage of being able to transmit a noise-free signal over considerable distances.

However, time moves on and the Microtach is no longer available. The fibre optic cable, sending and receiving optics also degrade over time, affecting system integrity and reliability.

 

Link Rack

Fortunately, Optima can upgrade your ageing Microtach units with a modern equivalent that has exactly the same mounting arrangement. We also supply a new coupling with every encoder.

We use our own proven high-quality multi-sheathed cable to give the same reliable signal quality for the wired encoder equivalent. Distances up to 100 metres have been achieved with no signal degradation.

For this, or any other LINK hardware or software support, just get in touch. With over 100 years of combined experience engineering (and for some, designing!) the Link hardware, we have a solution for your obsolete hardware.

Re-commencement of commissioning on major projects

Posted on

Critical process industry can’t stop, so Optima have been back commissioning on-site for some time now to support our customers.

For this major project, we have written the PLC and SCADA platform to control the whole process from start to finish. The application is written entirely in TIA Portal with a total of three WinCC SCADA platforms. We have used the latest cloud-based remote access technology so that most of the plant can now be commissioned remotely. Remote access using a combination of local Wi-Fi and High-Gain 4G antennas gives us a reliable and secure access to the PLC and SCADA system when it is required.

This project is just one of many that Optima play a key role in. Whether your application is large or small, we have a capable engineering team that are able to provide you with as much engineering resource as you require.

Supply of Motor Generator Test Rigs to Blackpool & The Fylde College

Posted on
AC and DC Motor Test Rig 1

If you want to learn about Asynchronous and Synchronous AC machines, DC Motors, Generator and Motor principles it’s useful to be able to carry out practical work on them.

Step forward Optima who helped Blackpool & The Fylde College fulfil their requirements to have two new state-of-the art installed at their brand new training facility near Fleetwood

Challenges

There were a number of key challenges in the design. On Test Rig 1, the AC Motor would operate in two modes:

  • Prime mover, with the load being applied by the DC motor.
  • Generator mode with the DC motor driving the AC motor.
Synchronisation Meter

When acting as a generator, the AC motor would have to be synchronised to the mains supply before being “switched-in”. This is to simulate a real-world situation on-board ships where back-up generators may have to be manually switched-in.

Design

The panel design incorporated banana type sockets to facilitate the ease of connection of external measuring instruments such as power meters.

The panels incorporated a host of instrumentation to afford total visibility. These included:

  • Machine torque
  • DC Armature Current
  • DC Armature Voltage
  • Single Phase Mains Voltage L-N
  • Single Phase Alternator Current
  • Single Phase Alternator Voltage L-N
  • Alternator Excitation Current

Test Rig 2

Test Rig 2 incorporated the very latest Siemens PM250 Regenerative Power Module and a Soft Starter to the test rig AC Motor. The user has the option to switch between the two. A DC Motor acts either as a prime mover or generator giving ultimate flexibility in operation.

The incorporation of a regenerative AC solution brings the very latest in cutting-edge drive architecture to an educational establishment. There aren’t many drive manufacturers who can supply lower-power regenerative modules.

Overall, the test rig projects were a great success combining the College’s and Optima’s knowledge to product test rigs that will serve students well for many years to come.

Safety Control System Upgrade

Posted on

Pilz Pnoz Multi Guardmaster Safety Relays

Optima recently completed an installation for a complete upgrade of a machinery safety control system.

The project required the bespoke manufacture of control backplates and the integration of multiple hardware elements including AC drives, DC Drives, Pneumatics and Hydraulics.

Optima have achieved the Machinery Safety accreditation qualifications as specified by TÜV SÜD Rail GmbH. Other integrators may supply machinery safety systems, but do they have the qualifications to back this up?

Optima can provide the assurance you need that our systems are designed to the correct performance level (PL) or safety integrity level (SIL) that your machine requires. If you don’t know what the PL or SIL value should be , we can also provide independent PUWER reports through our network of surveyors. Whatever your safety requirements are, Optima have it covered.
