O.E.M. Digital engine management unit contains components thatare now obselete. The cost for a new system was £15,000.Servotech ‘reverse engineered’ the unit and replaced thecomponents with modern electronics. This not only allowed thecustomer to save many thousands of pounds, it also enabled thelatest technology which allows the gas engine to run efficiently.

①

A customer had a fire within the gas engine container. Thisresulted in part of the wiring harness loom to be destroyed. TheO.E.M. held the harness for three days and quoted two weeksdelivery. Servotech collected the harness from the O.E.M. andproduced a new harness within three days.

②

A bank of six gas engines had been out of action for five days dueto a power supply failure. The power supply was collected fromsite, repaired and returned within 24 hours. All six engines werereturned to action.

Due to a misunderstanding, the air conditioning systems in thedriver’s cabs were never installed at a tram company. Servotechwere asked to design a control P.C.B., prove the system andcommission. With the assistance of an aircon specialist,Servotech produced a P.C.B., connected all equipment andenabled the system to be fully functional.

①

Many of the trams at a tram company were failing due to ‘overtemperatures’ in the drive control systems. This was due to a lackof ventilation in the cases of the drive control systems. Obviously,cutting external holes in the cases was not acceptable, due to thisallowing moisture ingress. It was decided to install cooling fansinternally to ‘stir’ the air away from hot components, allowing theair to cool sufficiently to prevent ‘over temperature’ in the drive.

②

A tram company had to convert the radio systems to digital fromtheir existing analog format. Servotech were asked to provide theinterface between the two systems. This project was extremelycomplex, having to liaise between a digital supplier and the tramcompany. With support from all parties, the project was completedwithin budget, and on time.

Servotech were asked to support a water utility in theirmaintenance and commissioning of uninterrupted power supplies(U.P.S.) within their catchment area. Servotech have surveyed anumber of sites, and have arranged for follow-up visits to eitherrepair or replace broken units.

①

Obsolescence was causing a power utility many problems due toequipment being deemed unrepairable by the O.E.M. To replacethe battery back-up systems was going to cost millions of pounds.Servotech were asked to evaluate the obsolete boards andestablish if the equipment could be supported. In general, when aP.C.B. is deemed obsolete by the O.E.M. there is a period of timebefore the individual components become obsolete.

Consequently, Servotech can continue to support the equipmentby sourcing components individually and repairing the P.C.B.s.

Several ‘oven temperature’ faults were detected by an engineer inthe north of England. It was obvious that a method of cooling wasrequired. Due to the abundance of compressed air available, itwas deemed suitable to use ‘vortex’ tubes to carry out the coolingon two specific large A.C. drives. The installation of the coolingsystem was carried out on a Sunday to prevent any productionissues.

The end result was a cabinet that did not fail due to ‘oventemperatures’.

①

A food processing customer was losing A.C. drives on a regularbasis.

Servotech identified the common failure mode and rebuilt thecircuitry to include voltage protection. This ensured that the drivesdid not fail.
