Blue Melon gaat samen verder met eMbed Engineering onder de vlag van eMbed Engineering! Met het samenvoegen van beide bedrijven is een stabiele en slagvaardige organisatie ontstaan die flexibel is en garant staat voor kwalitatief hoogwaardige producten. Ons uitgangspunt hierbij is dat we u nu nog beter van dienst kunnen zijn in het ontwikkelen van elektronica. Het samenvoegen van beide bedrijven heeft ook geleidt tot een uitbreiding van het portfolio en een enorme toename van competenties. Competenties die uiteen lopen van hardwareontwikkeling op chipniveau, tot higher level embedded software op basis van embedded Linux met internet connectiviteit. Hierdoor zijn we in staat om met parate kennis de meest uiteenlopende projecten in korte tijd tot een succes maken.

Vanaf begin december is eMbed Engineering te vinden op www.eMbed.nl. Op onze vernieuwde website kunt u naast informatie over eMbed Engineering als organisatie een selectie van ons portfolio vinden. We hopen u met dit bericht volledig te hebben geïnformeerd over de ontwikkelingen bij eMbed Engineering. Als u vragen hebt over de situatie of de ontwikkelingen, dan kunt u ons uiteraard bereiken via onze contactgegevens.

Deze website wordt niet meer bijgewerkt, bekijk de nieuwe website van eMbed Engineering!

If you can not solve the problems after reading the help below we advise you to consult the manuals of the devices connected to the BluePower.

How much power do my motors need?

 For example 3 Vexta PK266-E2.0B motors. Specifications:
 Coils connected in series
 Internal resistance of R = 2 * 1.8- Ohm
 Maximum current 1.4A 
 

 Nessesery power: (I22R) * 3 = 21- Watt

If I turn off the device, the status LED is not switched off

In this case the device is actually turned off, however there is no connected load. The BluePower contains high capacity buffers to support peak currents which are needed to for example drive motors. When you turn off the device its connection with connected appliances is severed, which results in a non existing load. The BluePower's buffers (consisting of large capacitors) will keep their charge for some while. The led will stay lit until the energy stored in the buffers is used up. This can take upto 5 minutes. By temporarily switching on a connected external device you quickly drain the BluePower's buffers.

When I turn on the device the status LED is not lit

If the led does not switch on check that:

1. the device is connected to a grounded mains power supply.
2. the power cord is connected to the 230V connector at the backside of the BluePower.
3. the fuse is in order. Replacing the fuse is described in the manual.
4. the power switch is switched to '1'.

The status LED is switched on, however my BluePower powered external devices are not working

Verify that:

1. in case of a connected BlueStep, the power supply cable between the BluePower and BlueStep is correctly connected. Is the screw fastened in the plug?
2. the power switch is switched to '1'.
3. all connected cables are undamaged. Replace damaged cables immediately!
4. if you have soldered the cable yourself that it is not defective.
