PUMPS AND FANS ON/OFF MONITORING WHITE PAPER

When knowing the motor is running makes the difference.

Turning a motor ON doesn’t automatically mean that it is running. There may be failures around and the control system (a PLC or a Building Management System - BMS) must be informed that the action is not happening. The usual question is “How valuable is it to know this early?”, to be able to trigger actions and deploy countermeasures. We’ll address the most important aspects and propose some solutions to increase the value of the performance in applications such as water circulation pumps and fans.

INDUCTION MOTOR ENERGY EFFICIENCY REGULATIONS WHITE PAPER

Benefits of using soft starters with high efficiency motors.

Industrial electric motors account for roughly 50% of the worldwide power consumption. Worldwide initiatives have been put in place by different countries in relation to the efficiency improvement of electric motors. Higher quality and more efficient motors have the potential to reduce energy use significantly. The challenge with higher efficiency induction motors (IE 3, IE 4 classes) is that of the higher starting current. Such current magnitudes may cause undesirable effects on the voltage network and may also cause protection circuits to trip. This paper covers the various challenges posed by high efficiency motors and how soft starters as well as variable frequency drives can help users overcome such issues.

DUPLINESAFE WHITE PAPER

How to limit downtime costs due to emergency stops in material conveyors.

This document is aimed at enabling system integrators, engineers and maintenance managers to make the best design choices, while designing and planning safety systems onto conveyors. Also installers could take advantage by reading this document, especially in the commissioning and maintenance phase of their installation’s lifecycle. Plant owners and purchasers could also find useful information on how to improve the total cost of ownership of their assets, so as to save money in the short/medium/long terms.

SOFT STARTERS WITH MOBILE GENERATORS WHITE PAPER

How to overcome generator sizing issues and reduce system costs with soft starters.

Use of mobile generators is increasing and becoming more popular due to the growing trend of off-grid living but also as backup power for residential homes, due to the frequent power brownouts caused by adverse weather phenomena. Starting inductive loads, such as pumps and compressors, via generators might cause frequent trips due to the high starting currents of such loads. This document outlines the issues existing today with proper sizing of generators for inductive loads and also gives practical examples of how soft starters can help overcome such issues whilst helping to reduce system costs.

PUMP ALTERNATING WITH FAILING PUMP DETECTION WHITE PAPER

A straightforward solution to reduce down time in pumping stations.

Managing alternating pumps may be complex but can be made much simpler when the task is under the correct focus. We will introduce some alternating pumps application examples, together with some ways to ensure the correct working mode even in case of failure. As a bonus, the solution highlighted doesn’t require investments or programming skills being plug and play.

SOLID STATE RELAYS WHITE PAPER

The benefits of utilising a heat sink at a higher temperature.

Heatsink sizing is one of the most critical steps when using solid state relays (SSRs). The heatsink provides the necessary thermal dissipation for the power losses in the SSR power unit. This paper gives a detailed thermal analysis of the SSR and heatsink and proposes ways how OEMs can:
- Save space in the electrical cabinet
- Increase the load current in the SSR
- Save on overall system cost
