Question about Robinair Cool Tech 34700Z Recovery, Recycling, Recharging

Open Question

It will not charge, I can't change the amount of charging waight (00 all the time).

I can't charge but i can recover 37lbs (the display says)I do have gas in it. There is sub menu (where I clear the filter and vacum time) to calibrate scale- first it asks if zero so I press ok, then some numbers that can be change and again I press ok. Unfortunatelly it doesn't solve the problem.

SOURCE: PROBLEM WITH WEIGHT CALIBRATION

Calibration procedure for Robinair AC machine.
NOTE:FOR SCAL CALIBRATION YOU SHOULD HAVE 9KG/20LB OF WEIGHT.From main menu go to change default (press 8787 for old type machine or 5454 new type machine)
then press enter/start key.after enter to default nenu you have to select calibrate scal option.press again enter/start key then follow the on scree message.once you done so,press stop/exit key to complete the prcess.

SOURCE: Over charging won't recover scale don't work

It is not clear which model of robinair machine you have! However your machine need to re-calibrate the scale.

SOURCE: over charges. machine seems to operate normal, but

It seems to be your last calibration was not correct!
For Robinair Model-34700z scal calibration follow as bellow:
Form the main menu go to ''CHANGE DEFAULT'' then press 5454 & YES key (passwoed to access default option).Once you enter to default menu,go to "SCALE CALIBRATION" & press YES key. now follow the on screen text.
NOTE:you should have 9KG/20LBS of weight for scale calibration. Do not change ''TANK TARE''. it must be on factory setup 16.30 lbs OR 7.40 kg.
Hope this will help you to solve thr problem & if my solution is useful to you please vote for it

According to this charging system isn't working correctly ! This is a computer controlled charging system .
Principles of Operation
The powertrain control module (PCM) controlled charging system determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator. This system is unique in that it has 2 unidirectional communication lines between the PCM and the generator/regulator. Both of these communication lines are pulse-width modulated (PWM). The generator communication (GEN COM) line communicates the desired setpoint from the PCM to the voltage regulator. The generator monitor (GEN MON) line communicates the generator load and error conditions to the PCM. The third pin on the voltage regulator, the A circuit pin, is a dedicated battery voltage sense line.
The charging system voltage is controlled by the PCM. The generator charges the battery and at the same time supplies power for all of the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to the battery temperature by using a signal from the intake air temperature (IAT) sensor. This means the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged (the PCM recognizes this and increases the output of the generator to accommodate), the system is also able to increase the idle speed to increase the charge.
To minimize the engine drag when starting the engine, the PCM does not allow the generator to produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM turns the charging system warning indicator off after the engine is started and illuminates it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The charging system warning indicator is also illuminated by the PCM whenever the key is ON with the engine OFF.
This is a System 4 charging system, which uses the GEN MON and GEN COM lines to control and monitor the charging system through the PCM. System 4 charging systems are virtually identical in design and therefore, share the same diagnostics. The circuit numbers and colors may be different, but the functions are the same.

How long does it take to fully charge a wheelchair batteries


If the batteries were discharged completely, the battery charger isn't strong enough to start the charging process. Take the batteries out and charge each one separately with an automotive type battery charger that is NOT automatic. This may take a day to recover this way. When the battery shows over 10 volts with a dc voltmeter you can re install them in the chair to complete the charge with the 24 volt charger. If the batteries have any amount of age past 2 years, it's time for new batteries.

I moved into a flat with newlec NLSH24AN HEATER N NO INSTRUCTION. ..HELP


Hi Sharon,
This should be relatively easy.
You have storage heaters that only take in the hear during cheap rate electricity (at times you cannot change - typically between 00:00 and 07:00 but times vary - ask your electricity supplier).
.
The controls of an electric storage heater normally consist of two
dials to be found under a flap on the heater.

The input dial, sometimes known as the charge or overnight dial.
This control sets the amount of heat to be stored during the night.
It is best to be set on a seasonal basis: medium for
autumn/spring, high for winter.
If you find that you run out of heat before the end of the day,
and the Input is not on maximum, turn it up to store extra for the
following day.

The Output Dial sometimes known as the room temperature or boost dial.
This dial controls the amount of warm air or convected heat given out during the day. It opens and closes.

What happens if you would add a charge to a running system that has a low charge on a 404a system and you charge thru the suction as a vapor. I had a memory lapse and have charged 410 systems as a liquid...


as long as you recovered the charge, pulled a vacuum, changed the filter/dryer, and added the correct amount of refrigerant as a liquid, you should be good to go.

I was charged by microsoft for xbox 3 times last week for $4.99 what is this for? I have not purchased anything this month?


If you do not have any sort of auto-bill in place and have not made any purchases, you are definitely going to want to contact Microsoft and inform them of unauthorized charges. Unfortunately, if your live account is compromised and you have payment information stored, anyone who can log in can make charges. If you can still log in to your X-box live account, it would also be recommended to change your password.

Nuvi 750 wont turn on even when i hold the on button for a minute or more


Looks like the in-built rechargable battery is fully discharged. Try charging it for good amount of time like more than an hour through Car or computer charger. Keep the unit off to maximize charging.

Is it normal for my Garmin Nuvi 756T battery to go flat after only 30 minutes?


No. You can expect up to 4 hours of use - depending on the battery's state of charge, level of back lighting, use of Bluetooth or playing MP3s - all of which reduce battery life.

Try fully charging the battery overnight via USB cable to a computer. This will fully charge the battery, and afterwards, the car charger should keep the battery fully charged - provided you do not allow it to fully discharge. If it does, the car charger may not be able to charge the battery until it is charged via USB again.

DOES ANY ONE KNOW, HOW LONG A MOBILE CAN BE CHARGED...


OK, on the first original charge that is required when you first purchased this unit, it can charge for at least 8 to 10 hours. this is called a set up charge. After the first original charge, it is recommended to not charge over the set amount of time given by the actual cell unit. your phone will beep or, display a completed charge message after the charge has been completed successfully. if you go over the set charge, this can damage most cell battery's. Standard charge time after the original set charge is 2 hours.

Nuvi 200 does not charge all the way only 2 bars at a time


How are you charging it? With the computer? Some computers have a limited amount of current on the USB port. The best way to charge it is with the car adapter or wall charger. if that doesn't work, then you may need a new battery.
