Back in 2004 Lester's introduced an Omron drive repair service to its client base. Since then many of you have taken advantage of this service which has proved to be of value to you all.

Moving forward we are now in a position to repair the German manufactured drives supplied with our controllers. Dependant on the nature of the fault, we will either repair at Lester’s factory or use our contacts in Germany and dispatch the drive for repair there.

Hints and Tips on Drive Care.

Check to see if the Installation Protection cover has been removed at the top of the drive, as this will help ventilation and cooling of the drive. (Omron only)

Check that the fans are working, especially if the drive has been switched off and on. If necessary the fans can be cleaned with a soft brush.

If a drive has failed check the condition of the Main Contactors as they could also need replacement.

High Resistance across contacts will cause premature drive failure.

Check the condition of the main windings of the motor, both resistance and insulation to earth.

Intermittent interruption of the safety line whilst the lift is moving. E.g. lock tips, governor tension weight switch bouncing ,ect ect will cause the drive to shut down and restart immediately. This will reduce the life span of the drive.

Excessively hot motor rooms will reduce the life span of the drive.
