Manitou 625 safe load indicator problems.

[Azza123]

Hi, i have a Manitou 625 2013, all the leds are lighting up as soon as mechine is running, telescopic boom wont extended, can be overridden by the parachute switch. Is there a way to bypass this completely? Only me driving said mechine. Thanks

Try a calibration first, otherwise it's probably the sensor on the back axle damaged or come loose.

Thanks for the reply. I was also told by unbolting said strain gauge would bypass the whole system?

A friend told me that a cable tie around the sensor on the back of the boom (where it is only touched when the boom is fully retracted) will solve the problem temporarily.

only if system is working right in the first place.

Would think it highly unlikely you'd be able to disable it, used to be able to pull the fuse on really old machines now if you unplug anything it goes into overload. Has likely lost either the low or high calibration points, so you'll have to find out how to calibrate it

there should be errors codes on it, with out knowing these cant really pin point the problem. Unbolting the axle sensor will not bypass the problem, you need to fix it for which you need to start with the error codes on screen or on the read out display itself.

Then a skill fully applied cable tie can render the cut outs inactive at your own risk of cause.

@ACEngineering thanks for the reply, no error codes showing on the dash.. Just all the led lights lighting up with the alarm sounding.. stumped at the minute with what it could be? Awkward filling the feeder wagon by holding the parachute button

Should also ad, tried the calibration method for the strain gauge

it has to have one, red ! mark up on the top corner of the SLI display

Works well can get back wheels 2ft of the ground and still pull the boom back in

@ACEngineering error code

There will be more i suspect as that error code is just saying there is a fault with the sli calibration and to turn key off and back on to re check. See attached how to read error codes.

@ACEngineering

520387 code is fault with boom retract switch
520392 code is fault with boom height angle sensor

I would start from scratch with the calibration then see if these errors change. See below link to handy youtube video, this basically applies to alot of manitou models 2010 onwards. Note you do not need to actually pick up a load with these, you can instead just place a jack under the chassis and lift the machine off the ground so the rear axle is dangling. You do not need a load becuase the saftey margin of the sli is already built in to the machine ECU, unlike older machines where you manually adjusted the saftey margin to what ever you wanted.

@ACEngineering thanks very much, had a quick look earlier, a cable tie on the telescopic sensor at the back done the trick to get me going. Will have a look at doing a calibration tomorrow.

May need to cut cable tie off to do calibration, not entirely sure as not tried with one tied up before.

If it's all working properly then the cable tie does not affect the overload display so it will still indicate via the display if you overload it just it will not restrict the hydraulic movements.

Obviously this is at your own risk though as machine no longer meets the legal requirements for safe load indicator operation.

@ACEngineering cable tie in place is allowing full use of boom and telescopic in and out. But led's on the SLI still flashing, and alarming still. Will look deeper in to it.
