![]() With the coach sitting at normal ride height and engine off, drain the pressure in all coach air tanks down to zero. But, the program only moves on to raising the coach when lowering is no longer effective. The program does start out by lowering the coach - that is true. In fact, the auto leveling program only cares about action and reaction. If the pressure in either front corner of the coach goes below 10psi then the associated pressure switch on the front 6-pack manifold will inhibit further lowering of the opposite corner. The only air pressure that would have any bearing on the auto level function is the pressure in the front air bags. It is my understanding that the HWH 600 Series automatic leveling program does not give a hoot about the air pressure in your tanks. ![]() Once there, it will only level by using the aux compressor to add air to the BAGSI must respectfully disagree with this statement. Quote from: Twig - December 03, 2020, 07:31:33 am To simply things, on auto level the system will DEFLATE air bags to level until there is <80 lbs of air pressure in your tanks. Where we are now the pass side faces south and the sun warms the airbags on that side more than the other and we have made no adjustments yet. Maybe not perfect but close enough for us. Maybe once more several days later and we will generally be level enough for several weeks. A day or so later as temperatures stabilize we usually make a slight adjustment (usually letting air out of the driver’s side). We get somewhere, switch into manual mode and level the coach. The level system will not try to adjust itself and the compressor should not come on unless you make an up adjustment. You can adjust the coach’s level using the buttons to raise or lower front/rear/left/right as needed. This leaves the level system on but in manual mode. If you want to manage your level system manually, while the ignition is still on press the air button just once instead of twice. The smaller HWH compressor that you have is on a 15 amp circuit breaker. The coach was in the barn and plugged in. ![]() Maybe so but my first compressor ran for days until it was worn out. Twig, I don’t recall reading about any part of the HWH level system that will shut the compressor off after 15 minutes if it is not level. Oldguy has n extremely rare FT, one with no air leks. How much battery it will use depends on how often the 12 volt compressor runs, which depends on how tight your air system is. The box will will remain on until the "OFF" button is pushed, but will not go into a sleep mode. After leveling the vehicle the control box will return to the sleep mode.ĮXCESS SLOPE: During the leveling mode, either initially or after a sleep mode, if the coach cannot be leveled in 15 minutes the control box will stop all operations, and the "EXCESS SLOPE" indicator will come on. If a light is on or comes on and remains on for 60 seconds, the control box will relevel the coach using the original leveling procedure. After 30 minutes the control box will wake up and monitor the yellow lights until leveling is needed. SLEEP MODE: After leveling the coach the control box will remain on but inactive for 30 minutes. When all the yellow lights are are out, the control box goes into the sleep mode. During any raise (UP) function the compressor may run. After 2 minutes if the coach is not level, the computer will switch to the "UP" mode, inflating air bags according to lit yellow lights. If there are yellow lights on, leveling will start in a down mode, deflating air bags opposite to lit yellow level indicator lights. If there are no yellow lights the control box will go directly into a sleep mode. The coach will automatically level itself. The indicator light above the "AIR" button will start to flash.ĭ. The four red warning lights will be on.ī. Push the "AIR" button one time to turn the system on. To answer your own question all you have to do is read the manual:
