Looking for duty cycle relay

I need to buy or build a 12V DC duty cycle circuit. More specifically, I'd like to have a circuit or relay that can set separate run and off times to control a small light duty compressor filling up a larger tank. I'm looking for a run time adjustable to maybe 1 to 15 minutes, then an off time of maybe 5 min to 1 hr. Anyone know of an existing product, or decent circuit that I can build. I am semi familiar with relays like the Dayton 6A855, and magnecraft TDRSOX/SRX Time Delay Relays. but I want to be able to set the on /off times seperately. not sure if I can easily do it with those type relays.

SOURCE: wiring a dayton timer relay

If i understand you correctly you want to push the button, release it and have the timer give power to the solenoid for 3 more seconds, correct? If this is the case you will need an off delay timer. On delay timers work like this. You push the button, power goes through the timer, at this point the timer starts counting, when the timer reaches its preset point,(3 seconds we'll say) the contacts change till the power to the timer goes off.

If you hook this up with an on-delay timer this is what will happen:
Push the button and release, the timer will tick as long as you hold the button down, till three seconds, then the solenoid will raise until you release the button.

With an off delay this will happen: push button , solenoid begins working, when button is released timer counts 3 seconds while solenoid is still working, then removes power to the solenoid.

The way you would wire the off-delay is like this:
Connect line side of your pushbutton(incoming power side),incoming power and terminal 1 on your base together. next connect the load side (outgoing power side) of your pushbutton and terminal 2 on your base together. Connect terminal 3 to the hot wire or terminal on your solenoid. Lastly connect terminal 7 the incoming neutral wire and the neutral wire or terminal of the solenoid together.

I am telling you how to wire it in my head, if you'll write back with some specifics such as what wire you will use, where your getting power from,what the solenoid current draw is and such i can get a little more detailed. maybe it will make more sense.

Also make sure the timer and pushbutton are rated to handle the solenoids running current. The timer appears to handle 10 amps im not sure what you pushbutton can handle. Also keep in mind the solenoid will operate for whatever time u set it to, after the button is released. There are other ways to do it but this would be the most economical way.

And of course turn the breaker off and test that it is off before working on the circuit. Write back with any problems.

SOURCE: i have a lighting control

Hi,
Usually whn you get a chattering like that you have a bad neutral...therefore a low voltage condition...
Check for a loose wire or a bad wire but connection... also maybe try to run an isolated neutral to that coil...

The other thing that can cause that is if the hot wire for that coil is run through another coil instead of running in parallell...the coil cuts the voltage... it maybe that something is wired wrong and that is what is happening...

SOURCE: We have a Dayton Relay,

Instructions on link below
http://waterheatertimer.org/How-to-wire-Dayton-Off-Delay-Timer.html

Maximum Load wattage on Dayton is 1 amp.
So timer will work with 10 watt load.

Push button is 120Volt.

Wondering if there is more than one fuse for operating power windows on a 1994 ford explorer sport


check under the bonnet in engine bay for a plastic box with relays in it. Check the voltage going to the sockets that the relay sits in when you push the power window button. Use a cheap 12 V probe (google it or go to a car shop like repco to get one) it lights up when + 12 V found. there may be fuses there as well.
cheap probe looks like this

Headlight low beam on my envoy 2006 not working


The headlamp driver module (HDM) is an electronic module that provides electrical power to the vehicle low beam headlamps. The HDM is controlled by a pulse width modulated (PWM) ground signal from the body control module (BCM). The BCM determines the desired lamp intensity using the ambient light sensor, multifunction switch and the park brake switch as inputs. In general, the HDM will operate in 1 of 3 modes:
?€¢
Reduced Intensity Mode: This mode is used by features that do not require or allow maximum low beam headlamp intensity such as daytime running lights (DRL) (nominal: 85% duty cycle).


?€¢
Full Intensity Mode: This mode is used by features that require full low beam headlamp intensity such as low beam headlamp operation in manual or auto modes (nominal: 100% duty cycle).


?€¢
Off Mode: This is the default mode of the system that will occur when none of the features described above are active. The BCM will deactivate its PWM output (0% duty cycle) during this mode.

The normal battery voltage input to the HDM must be between 6 and 16 volts DC to operate. Any deviation to these values could cause improper operation.
Major components of this system are the BCM, HDM, ambient light sensor, multifunction switch, park brake switch and low beam headlamps.
DTC B2575 Headlamp Control Circuit
When the body control module (BCM) senses a request for headlamp or daytime running lamp (DRL) illumination, the BCM sends a pulse width modulated (PWM) ground signal to the low beam headlamp driver module through the low beam headlamp driver module control circuit. The low beam headlamp driver module will illuminate the headlamps, adjusting the intensity based on the PWM signal received

MY SHREDDER IS OVERHEATING


Significantly Improve the Manufacturer's Suggested Duty Cycle, from Intermittent Use: ON=6min / OFF=30min to CONTINUOUS USE

ROYAL PX1201

My comments below are addressing these 3 issues:

1 How to permanently fix the motor overheating

2 How prevent motor thermal shut-down

3 How considerably improve the duty cycle


I am sharing this info with you with the hope it may save you some time.
Did purchase this unit from Costco about 6 years ago, in 2010.
This unit is functioning well today except its motor was overhearing and going into automatic thermal shut-down.
The ROYAL PX1201 model # is PCUA: 29127H-FE ; the Lot # 111155925.
Had to open the motor enclosure quite few times for cleanup and cooling.
Note the manufacturer's recommended duty cycle is ON=6min / OFF=30min. Nobody I know has 30min time to babysit a shredder.

In thermal shut-down mode the motor would not turn in any direction.
Today I modified the ROYAL PX1201 by adding an external 12V DC computer fan for motor cooling.
Cut a fan-placement, round, 3.25inch hole into the shredder top, at the upper right of the paper-insert slit: ____O
External, room-air is being forced into the motor-and-gear enclosure at all times, non-stop.
The paper-insert slit provides the hot-air exhaust.
The fan is an ordinary plastic PC fan: 12V DC, 0.12A=120mA, XYZ=72*72*20mm ; diagonal=101mm (hole-to-hole).
Fan cost is around $5.- and the fan power supply was a separate 12V DC adapter.
Did not have time to electrically connect the fan to the shredder's internal power supply.

Today I used the shredder continuously for 8 hours with neither overheating nor thermal shutdown.
Did fill TEN 13-gallon plastic bags with shredded paper / hand compacted confetti.
On average I shredded 6 letter-size, normal thickness pages at a time / per feed, continuous feed for about 8 hours.

I NEED A REPLACEMENT FAN MOTOR. ANY INFO ON SPECIFIC CONTACTS TO PURCHASE MOTOR/


In the model number... I'm not sure of the fx and ms, but the 80 and 25 is a standard 80mm case fan that is 25mm thick. I tried a standard .2amp case fan that I had on hand and the circuit board did not like that..it got hot. I got on ebay and looked at dozens of 12v 80mm fans until I found one that was 0.09amps. That was as close as I was able to find without much more looking. The fan works very well although not quite as much airflow as the new crane humidifier that I put next to it but it doesn't overheat and does the job for about 7 bucks.

I have a horn that sounds when my hay baler chamber is full. I am looking for a timer relay that will allow the horn to sound for 3 to 5 seconds and then disconect the circuit so it won't drive me...


DEI 528T appears to be 12Volt 'wait to start' or ON-delay timer.
528 receives electrical signal, and then delays the start-circuit by up to 60 seconds.
For example home alarm system. Door is opened and alarm sounds. Install DEI 528 and set for 60 seconds: Door is opened and alarm will not sound for 60 seconds.

You need 12-volt off-delay timer.
Off-delay timer receives electrical impulse, and then begins a countdown.
After countdown expires, then circuit turns off.
ELK-960 appears to have off-delay feature for 12V DC

How do I fix code P1237 on ford taurus sel


P1237 - Fuel Pump Secondary Circuit Malfunction

Electronic Returnless Fuel Systems (ERFS) utilize a Fuel Pump Driver Module (FPDM) to control fuel pressure. The PCM uses a Fuel Rail Pressure Sensor (FRP) for feedback. The PCM outputs a duty cycle to the FPDM to maintain the desired fuel rail pressure. During normal operation, the PCM will output a FP duty cycle from 5% to 51%. The FPDM will run the fuel pump at twice this duty cycle, e.g. if the PCM outputs a 42% duty cycle, the FPDM will run the fuel pump at 84%. If the PCM outputs a 75% duty cycle, the FPDM will turn off the fuel pump.

If the FPDM does not out any diagnostic signal, (0 or 100% duty cycle), the PCM sets a P1233 DTC. This DTC is set if the FPDM loses power. This can also occur if the Inertia Fuel Switch is tripped.

If the FPDM outputs a 25% duty cycle, it means that the fuel pump control duty cycle is out of range. This may occurs if the FPDM does not receive a valid control duty cycle signal from the PCM. The FPDM will default to 100% duty cycle on the fuel pump control output. The PCM sets a P1235 DTC.

If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC.

Check engine light on..code short runner valve control malfuction


P1004 - SHORT RUNNER VALVE CONTROL PERFORMANCE

Sound like something came loose. If you cannot find it you need to take it to the dealer so they can perform these diagnostics. Should be under warranty.

The engine performance and power output is enhanced through the use of the "short runner valve" (SRV) system. The SRV system allows the intake charge air to bypass the long intake manifold runners between the intake manifold plenum and the intake manifold interface to the cylinder heads by providing a shorter runner directly between the plenum and the cylinder head interface.

The SRV position is controlled by a pneumatic/spring actuator and electronic solenoid valve. When the solenoid is not energized (the "rest" position), the SRV is held in the closed position. When the solenoid is energized the SRV is moved and held in its opened position. There is a set of enable conditions including a minimum engine coolant and ambient temperature, SRV enable, and Powertrain Coordinator load enable condition. If any of these conditions are not met, then the SRV valve is de-energized (closed).

* When Monitored: With the engine run time above a calibrated value, battery voltage greater than 10.4 volts, ECT within a specific range, and the Short Runner Valve Assembly (SRV) control active.
* Set Condition: The Powertrain Control Module (PCM) compares the circuit feedback to a calibrated closed range, between 75% & 85% Pulse Width Modulated (PWM) duty cycle, when the circuit is de-energized or to a calibrated open range, between 35% & 55% PWM duty cycle, when the circuit is energized. If the value is determined to be out of the calibrated range in either the de-energized, greater than 85% duty cycle or less than 75% duty cycle, or energized, greater than 55% duty cycle or less than 35% duty cycle, state for more than a calibrated amount of time, this DTC will set.

Possible Causes
(F344) ASD RELAY OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE
(K237) SHORT RUNNER VALVE (SRV) SIGNAL CIRCUIT SHORTED TO GROUND
(K237) SHORT RUNNER VALVE (SRV) SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE
(K238) SHORT RUNNER VALVE (SRV) CONTROL CIRCUIT SHORTED TO GROUND
(K238) SHORT RUNNER VALVE (SRV) CONTROL CIRCUIT OPEN OR HIGH RESISTANCE SHORT RUNNER VALVE (SRV) ASSEMBLY
