| What is the reason for Heater blowing. | | 01/01/70 00:00 |
| Hof often/how we? | | 01/01/70 00:00 |
| Some more information... | | 01/01/70 00:00 |
| continuous rating | | 01/01/70 00:00 |
| This could be the reason... | | 01/01/70 00:00 |
| Way too much current... | | 01/01/70 00:00 |
| Some more information required... | | 01/01/70 00:00 |
| do you have hysteresis in your control? | | 01/01/70 00:00 |
| No there is no hysteresis. | | 01/01/70 00:00 |
| Four pulses? | | 01/01/70 00:00 |
| The Heaters are failing, electronics is OK. | | 01/01/70 00:00 |
| Why Pulses? | | 01/01/70 00:00 |
| I will do just that... | | 01/01/70 00:00 |
| Processor must know about zero-crossings | | 01/01/70 00:00 |
| ?? | | 01/01/70 00:00 |
| soft start | | 01/01/70 00:00 |
| Soft Start | | 01/01/70 00:00 |
| an easy and interesting check | | 01/01/70 00:00 |
| Soft start, again... | | 01/01/70 00:00 |
| Yes these heaters need Soft start | | 01/01/70 00:00 |
| Again: Power? Voltage? Current? | | 01/01/70 00:00 |
| Avoid driving gate all the way to next zero crossing | | 01/01/70 00:00 |
| Crest factor/power factor correction | | 01/01/70 00:00 |
| Phase angle control... | | 01/01/70 00:00 |
| I agree with you. | | 01/01/70 00:00 |
| Good luck! | | 01/01/70 00:00 |
| are all heating coils the same ? | | 01/01/70 00:00 |
| There You Go | | 01/01/70 00:00 |
| re the possible need for hysteresis | | 01/01/70 00:00 |
| Power? Voltage? Current? | | 01/01/70 00:00 |
| Alternate Heating Control Algorithm | | 01/01/70 00:00 |
| Some more clarification... | | 01/01/70 00:00 |
| Voltage - or power? [ed] | | 01/01/70 00:00 |
| The other controllers | | 01/01/70 00:00 |
| Thanks All members. | | 01/01/70 00:00 |
