Power linking projector, linear actuator (projector lift), and projector screen motor on one switch

I have a moorized projector screen - elite screen "silver max 92h" - And projector - epson powerlite- that I built a lift for using a firgelli linear actuator. The screen is a 12v dc motor and has an up/down/stop switch that connects to 110v outlet power (and I think uses 60hz resistance) The projector says "100-200V, 50/60 Hz, 3.2-1.4A" Linear actuator just has 2 wires coming out of it (thought it would come with a switch but it doesn't) and is 12VDC. With no limiter it will stop at full up and ful down positions which is perfect for my lift. My question here (if you've made it this far haha) is how do I possibly connect all of them to one switch that drops the screen, drops the projector (by powering the actuator) and also turn on the projector (and adversely will power down the projector and pull up the projector and screen by reversing polarity in the actuator and screen motor)? Hope that's not too confusing and thanks for any help you can provide I don't know much about this sort of thing. Also one idea I had was to tap the actuator into the line heading from the switch to the screen motor, they are both 12VDC so my hope is that the one switch would then lower them both, bur I don't know if that would work? Then I'd have to just figure out the projector power? HELP! Haha or at least let me know I I'm on the right track. Thanks a lot!! -MJ

SOURCE: USING 1 CHANNEL

I can't find any documentation for your amp; it was made when Jensen was owned by Recoton, and they're no longer in business. With any 4-channel amp, you can't bridge all four channels into a single channel. What you can do, if you're connecting it to a single sub, is to bridge two of the channels into one channel and leave the other two channels unused. It doesn't usually matter which two channels you pick, but some 4-channel amps designate channels 3 and 4 (or rear channels) for the subwoofer. Whichever ones you use should have a "LPF" or "LP" crossover setting available.

SOURCE: Designing a linear regulated power supply

what you are doing is over **** for 300 mA, now if you will pulling some real wattage then you would need linear regulation.
just use a 10.00 ac adapter . or a zener diode .
the calculations in real time analysis is complex GE has the formula online . but a spike at 300ma will be assorbed by the transformer easilly. if you are protecting delicate circuit then a fuse will not work quickly enough , fry and blow is all they do.
a crowbar circuit is what most designers use nowdays.fast and efficient.
There are plenty of IC regulators on the market that will give these specs but I think your are over thinking your needs unless you have an exact spec for medical research.

SOURCE: will 25 amp power supply pull 250-linear?

Yes it could, but... but it also depends on your antenna, what antenna are you using. Do not upgrade the power of your radio unless you know your antenna can handle the output power.

Power Sunroof System Components
The power sunroof system consists of the following components:
• One tilting glass sunroof panel--For sunroof vent functions
• Three sliding glass sunroof panels, which allow the sunroof to open in sections
• Power sunshade panel--An adaptable panel which is rolled out or rolled in and stored by the sunshade motor/actuator in order to cover or uncover the sunroof glass panels
• Power sunroof switch--A rotary style switch controlling sunroof switch signal inputs to the sunroof motor/actuator
• Power sunshade switch--A momentary press style switch controlling sunshade switch signal inputs to the sunshade motor/actuator
• Power sunroof motor/actuator--Comprised of both the sunroof motor/actuator and the sunroof electronic control module, it is sometimes referred to as the sunroof control module/motor assembly.
• Power sunshade motor/actuator--Comprised of both the sunshade motor/actuator and the sunshade electronic control module, it is sometimes referred to as the sunroof slave module.
Sunroof Motor/Actuator and Sunroof Switch
The sunroof motor/actuator assembly is located at the rear of the passenger compartment, above the rear view window, between the headliner and the roof structure. The sunroof motor/actuator assembly also contains the sunroof electronic control module and the two components are serviced together as a unit.
Battery positive voltage is supplied to the motor/actuator at all times through the 25-amp LAMELLA ROOF fuse located in the rear fuse block. Whenever the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the motor/actuator is also supplied battery positive voltage through the accessory voltage circuit and the 10-amp ROOF/HEAT SEAT fuse which is located in the body control module (BCM). The sunroof motor/actuator is grounded through splice S403 to body ground G302.
The sunroof motor/actuator supplies voltage to the sunroof switch through three internal resistors and three hard wire circuits. The 3 hard wire circuits are:
• Sunroof switch data 1 signal circuit
• Sunroof switch data 2 signal circuit
• Sunroof switch data 3 signal circuit
The sunroof switch, which is also grounded to G302, is a rotary style switch. When the switch control lever is turned in a rotational direction, the appropriate switch contacts and signal circuits for the selected mode are simultaneously opened and/or closed to ground in order to provide the appropriate combination of voltage signals to the sunroof motor/actuator. The sunroof motor/actuator interprets the signals, and then applies battery positive voltage and ground to the appropriate circuits of the integral power sunroof motor in order to move the sunroof glass panels. At the same time, the sunroof motor/actuator sends a serial data message, via the keyword 2000 serial data circuit, to the sunshade motor/actuator to open the sunshade panel in conjunction with the sunroof glass. As the sunroof glass panels slide rearward to the open position, the sunshade motor/actuator simultaneously rolls in the adaptable sunshade panel.
The sunroof switch is mounted in a bezel which is located above the rearview mirror.


Circuit/System Description
The sunroof system is controlled by the sunroof switch and the sunroof control module/motor assembly, which is also known as the motor/actuator assembly.
The sunroof control module is supplied battery positive voltage at all times through the 15A SUNROOF fuse located in the rear fuse block. Whenever the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the module is also supplied voltage through the accessory voltage circuit and the 10-amp ROOF/HEAT SEAT fuse located in the body control module (BCM). The sunroof control module is grounded through the ground circuit at G302.
The sunroof control module supplies voltage to the contacts of the sunroof switch through the sunroof switch close signal circuit and the sunroof switch open signal circuit. The sunroof control module also supplies ground to the switch contacts through the sunroof switch low reference circuit. When the switch is operated, the contacts and signal circuit for the selected mode are closed to ground, the voltage is pulled low in the module, and the appropriate signal is recognized by the control module. The control module then internally applies battery positive voltage and ground to the appropriate circuits of the reversible power sunroof motor in order to move the sunroof glass panel to the open, close, or vent


Do you know how to do electrical testing ?
Circuit/System Testing
Ignition OFF, disconnect the harness connector at the sunroof control module.
Ignition OFF, test for less than 1.0 ohm of resistance between the ground circuit terminal 1 and ground.
? If greater than the specified range, test the ground circuit for an open/high resistance.
Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 3 and ground.
? If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
Verify that a test lamp illuminates between the B+ circuit terminal 6 and ground.

What fuse is it for rear hatch actuator 99envoy


One fuse powers all door lock actuators . The other door locks work ? if so it's not a fues problem .
The following locking functions are included on the vehicle:
• All the doors unlock -- All the doors will unlock, including the endgate/liftgate, when any power door unlock switch is detected. The passenger doors lock directly by pressing the lock switches. The driver door unlocks by the BCM using a driver door unlock relay.
• All the doors lock -- All the doors will lock, including the endgate/liftgate, when any power door lock switch is activated. All the lock actuators will activate directly from the power door lock switch (external to the BCM).
• The end/lift gate lock switch -- All the doors will lock or unlock from the end/lift gate lock switch

You probably have a bad lock actuator

The windows are no exception , they are controlled by modules in each door an are connected by a serial data communication bus !
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a power window switch built into the driver door switch assembly (DDSA) , or, from a power window switch mounted locally on its associated door. The driver door window can be operated only from the driver door power window switch built into the DDSA.
When the driver door module (DDM) receives a driver door window switch request from the DDSA, the DDM examines the request and inspects to see if it has received any messages from any of the other vehicle modules prohibiting the movement. If no prohibitive messages have been received, the DDM then applies power and ground to the driver door window motor to move the window as requested.
When a passenger door module, passenger front door module (PDM), LH rear door module (LRDM), or RH rear door module (RRDM), receives a window switch request from, either the DDSA or the window switch mounted locally to its door, the passenger door module examines the request and inspects to see if it has received any messages from any of the other vehicle modules prohibiting the movement. If no prohibitive messages have been received, the passenger door module then applies power and ground to its associated window motor to move the window as requested.

Precor efx 546 error.


please follow this steps and fix it. God bless youError 43 - Zero Switch not FoundDescriptionThe C944 and several versions of C96X used a lift position identification system that did notutilize a potentiometer.Instead, it utilized a switch that would be physically actuated by the lift when the lift was in thezero incline position. A revolution sensor counted lifted motor revolutions to determinesubsequent lift positions. In addition two limit switches where used to remove power from the liftmotor if the lift moved outside of it's normal range.When the unit was powered up the lift would start to hunt for the zero switch. It would first go up4% (maximum lowest physical position was -3%) if it did not find the zero switch or it hit the upperlimit switch, it would then go down until did find the zero switch. When the zero switch waslocated it would stop, the system would then know its physical position and be prepared tomonitor the revolution sensor. If during this power up procedure the zero switch was not found anerror 43 would be displayed.Possible Causes1. The lift position actuator does not physically operate the zero switch.2. The lower PCA is bad.3. The zero switch is bad.Possible Remedies1. There are several physical problems related to the lift platform mounting or the plate the zeroswitch is mounted on that can cause the actuator knob to miss the zero switch as it movespast. Repair the lift platform mounting, repair or replace the lift switch mounting plate asrequired.2. The lower PCA provides a 5 VDC power source for the zero switch. You should measure 5VDC across the zero switch when the zero switch is activated. If the reading is significantlylow, remove both wires from the zero switch and repeat the measurement across the wiresremoved from the zero switch. If the reading is still significantly low, verify the zero switchwiring. If the wiring is intact and correctly connected, replace the lower PCA.3. Move the lift to position where the zero is switch is not activated and remove power from thetreadmill. Remove both leads from the zero switch and measure the zero switch with anohmmeter. The zero switch should read very near 0 ohms. While measuring the zero switchwith the ohmmeter, activate the switch by hand, the reading should change to infinite (open).If either of the above readings are significantly incorrect, replace the zero switch.

2000 gmc sierra truck windows will not work even after change motors


If you have a voltmeter/multimeter you can check the window relays to make sure they are actuating when you depress the button. You need to verify the power supply is regulating to the motor from teh window switches. Second thing you need to verify is that you changed not just the motor but the entire regulator assembly. no offense to some aftermarket motors but they are underpowered and produced in china, etc. They cant lift the heavier regulators in your truck that are factory regulators. Since it sounds like you are handy and replaced the motors yourself, then I woudl reopen the door panel and actuate the window switch. You will be able to see if the gears on the motor head are turning to actuate the cables on the regulator. If you dont see movement then the problem is with either the fuse assembly or power supply to the window switches. If you see movement then the issue is with bad regulators and or underpowered motors. If you purchase the motors from ebay, I would be suspicious of the motors... Good luck.

I just changed the bulb but the unit will not power on. I can hear clicking as if it is attempting to power on.


The problem with the bulb cover interlock(safety switch) tab is that it is molded with the plastic cover. When these projectors are ceiling mounted upside down, the heat from the bulb melts the interlock tab and causes it not to actuate the interlock switch.


If you push the switch arm in you can hear the switch click. The fix I did on my projector was to bend the switch arm so that it stays actuated. You can use a small set of needle nose pliers or two small screwdrivers. be careful to only bend the arm in the middle, if you break the arm from the switch, you will have to go in and bypass the switch.... Just be carefull...

After you bend the switch arm try to press it in, if you did it right you won't hear the click. install the lamp, cover, and your done.
