    Is 24V AC dangerous?

    Generally anything under 30v is considered safe (at least for the heart). It is said that as little as 0.1 amps of current can electrocute someone but at voltages under 30v the skin resistance is high enough to prevent currents from reaching dangerous levels. If you have a power limited 24vac...

    Using sensor output via relay to trigger a solenoid

    connell.richard, Yes, that should work but you may be able to eliminate one or even both relays if the timer has relay contacts build into it. You can use the NC contact of the existing K6 relay to directly send 120v via timer contacts itself, or the external relay associated with it. I...

    Using sensor output via relay to trigger a solenoid

    Something as simple as this might work.

    Using sensor output via relay to trigger a solenoid

    Connell.richard: Nice, but it doesn't look quite right. The Timer output goes to a NO contact of R1 so it'll do nothing. Even if you change R1 to NC contacts, it will switch on R2 but the solenoid relay won't energize. You'd need separate contacts on R2 to power the sol relay during your fault...

    Sump pump backup

    Photod, The reason it's usually not done is because its not practical. But yes, it could be done. Standard household Sump motors take a lot of energy to start-up because of their inductive nature. Usually about 2 or 3 times the normal running current. So the motor probably needs at least 8 or 9...

    Well that's somewhat discouraging but all is not lost. I would try and get some speakers hooked up as soon as you can. I'm of the opinion that your repair has probably corrected the initial problem but there's some software setting that may be holding up things. Perhaps forget the diagnostic...

    That doesn't sound right. I trust you had Q1,Q2,Q3 displayed as before? It displayed DVD on the screen?

    Do you mean the actual FL or FR speakers, or the output pins 21(FL) 23 (FR) of IC801? I would expect you should have the analog DVD signals input at pins 64/65 (DVD) of IC801 then output on pins 21/23. I'm not sure why they're not getting through. Perhaps wrong zone? U8 pin 100 comes from...

    Hopefully your firmware update was successful. You don't want to power down during that. Aside from that, If it still doesn't want to turn off, you could always use the low tech method of yanking the plug out of the wall. :D

    Ic801 seems to be doing its job of switching, so there's no reason to believe it won't switch the analog input through to the amp provided diagnostic mode item 1 is followed. (I'm crossing my fingers)

    Do it however you did it before,(pushing 3 buttons together) Whatever you did that made Q1,Q2,Q3 light up on the display. Then, follow item 1steps again.

    I know what you mean about there only being 5, but that's where I believe you need to be inputting your analog audio. Remember, It does say 2 channel audio (L and R). HDMI is not Analog. I would try all of the 2 channel inputs and make sure your in that diagnostic mode.

    I wouldn't assume that. When I hear Vaux I'm assuming auxiliary video that's digital. Try using an RCA jack and plug it into where it says "Audio" on the back. Only Analog audio is what we are asking it feed through while I that section (1) of diagnostic mode. Looking at other paths is...

    Congrats on the recording session. As to the AVR, I thought we were first trying to follow the analog path that's illustrated on page 35? We need to be on the same page here or we're both wasting time. After first entering diagnostic mode, try to follow what it says under section 4.5 for item...

    Look at the red lines on fig 7 of page 35. ANALOG inputs 1- 6 are passed through IC801 and sent on to amp. Forget everything except IC801. Make sure you use one of these inputs and if it doesn't output to amp you need to look at IC801.

    Follow the steps mentioned therein (turning off zone 2....etc.) The AVR should direct audio like fig 7 shows. Once you've done this try and see if you get analog through to the amp.

    Industrial saw burnt out relay repair

    It's an option for suppression of voltage spikes when motor is turned off. It is probably not necessary on yours but perhaps something they added for larger motor saw models.

    NO, not the same instruction. For remote Id you first hit power then hold the other buttons for 3 seconds. Sounds like you need to simultaneously hit all three. Try playing with it until you see the Q lights come on. Yes, it's the AVR buttons, not the remote buttons.

    Large motor start up

    30 amps under load is a bit vague. Whats the load? What does the motor name plate data say? It depends on several things like the motor type and duty cycle but a 60a contactor usually is adequate. Sometimes you can reduce inrush current by adding a NTC thermistor. But yes, a footswich and a...

    Michael. Try this. Hold buttons "Preset1" and "Status" down together and while they are down, hit the On/standby button. The Q1,Q2,Q3 should be on like this.
