Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software. ( Discuss) Proposed since June 2023.Ī pedal acting as a dead man's switch in a bucket lift truckĪ dead man's switch is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Thanks to everybody who has contributed to date.It has been suggested that Dead-man's vigilance device be merged into this article. Unless it is designed to do more than I am assuming.ĭoes anybody know of ready made panels that I may be able to adapt. Masses of chips which mamybe don't like the marine environment. It seems a very overly complicated panel. I already have the Nasas battery monitor so would only need to add sensors for both the fresh and waste water. I am very tempted to make a new panel using mechanical switches with breakers. Would anybody know if the board is more than a switching mechanism for the various electrical accessories and the monitoring of the battery and liquid levels. I have replaced the burnt out chip and repaired the damaged printed circuit board and at the moment the board is working again. ![]() But I am reluctant to buy another panel even if the price is reduced as this is the second panel to fail in 18 months ( Since the boat was new ). ![]() īavaria have made noises that they may offer some kind of deal for a replacement. Wurthers manufacture the 301 panel, but Bavaria refuse to allow Wurthers to release any service information. Bavaria seem to think they are selling cars not boats, and as such we have to wait for Haynes to bring out a manual Not sure this is a lot of help but hey ho. I guess you could look at all the components on the board and check the values, including the IC's ? A Google search on each item and its number may give you the various vales? Swapping out the relay solved the problem. However the panel indicated I was on, off, not working, Kaput! But, checking out the relays we found one was working only when there was a z in the month and battery volts were 13.5v or above. Immediately I suspected the fridge thermostat, because they really are a source of frustration. However, In the first month we had our new 37 cruiser one of the relays became erratic (the fridge). ![]() ![]() In theory you could trace back the trigger line following the positive from the power board? Not something I would want to do!!! This switches the high current circuit on (or off). The trigger energises a relay coil to close (or open) the high current contacts on the main board. The high current switching (power to a circuit) is triggered by a low current sent to the main board (power board) via a bank of relays (what we used to call contactors). It also functions as a monitor for various systems such as water levels, battery volts etc? The failed panel is basically a low current switching panel. I assume you have a reasonable knowledge of circuits based on your previous posts? Tony, I don't know if this is going to be of use? Here goes anyway.
