Grove TM9100 2009 Troubleshooting Manual

If you’ve got a TM9100 that throws an E18 overload warning when it shouldn’t, or the boom length percentage reads garbage, you need the factory diagnostic tree. Not a third-party rewording. This Grove TM9100 2009 Troubleshooting Manual from Hirschmann is the original OEM document – 53 pages of fault codes, transducer adjustments, and schematics that match the actual hardware on the machine.

Boom Control Interface: Where You Start

Page 4 gives you the Boom Control Interface layout. If you can’t read the console display or the controller won’t respond, this is your first stop. The manual assumes you know how to use a voltmeter for voltage and current. If you don’t, go study a Manual Transmission repair primer – same electrical principles apply. You’ll need a DMM that reads amps.

E18 – Front Outrigger Overload Warning (Section 1.5)

That E18 code isn’t a guess. Page 24 walks through the exact sequence to check the outrigger position sensors and the LMI calibration. I’ve seen techs swap out a perfectly good transducer because they didn’t follow the step order. This manual saves you that parts cannon approach.

Proximity Switch Adjustment and LMI Hardware (Sections 2.1 and 2.2)

Section 2.1 details proximity switch location and adjustment on page 38. Section 2.2 on page 39 covers the TM9100 Boom LMI Hardware – which transducers are where. You need the LG 152 length transducer and LWG 309 angle transducer specs. These are not generic parts. The manual gives you the factory adjustments so the boom doesn’t extend crooked or trigger false alarms.

Electric Schematics: Five Separate Drawings

Schematics are broken out by sub-system: Central unit (page 45), Bus extension (46), Turntable (47), Lower (48), Boom (49). If you’re tracing a bus error like E61 – Error in the bus extension (page 27), you need to know which wire goes where. Aftermarket manuals often combine everything into one illegible mess. This one keeps each section separate. Combine with the console boom control data display schematic on page 50 and you can isolate a communication fault between the DS350 and the LMI.

3 Reasons to Choose the OEM Hirschmann Manual

First, the torque specs and transducer adjustment values are Hirschmann’s own – not a reprint from a third party. Second, the diagnostic tree for “No tele function at all in automode” (page 30) is logical: check power, ground, bus, then transducer. Third, the manual includes the Proximity switch location and adjustment procedure that aftermarket docs skip. Compare that to a Manual Transmission service guide – the OEM version always wins on accuracy.

Who Needs This 53-Page Diagnostic Guide

Who should buy this? If you own a Grove TM9100, operate it in a rental fleet, or maintain a fleet of industrial cranes, this is the diagnostic bible for the DS350 boom control extension. I’ve talked to shop owners who spent three hours chasing an E61 bus error because they used a generic wiring diagram. With this manual, you can pinpoint the fault on the bus extension schematic in minutes. The manual is 53 pages – that’s tight, no filler. Every page is a procedure or a drawing. Beginners can use it, but you need basic electrical knowledge: ability to read a schematic and use a meter. The manual itself says that on page 1. If you’re a DIY crane owner working out of your pole barn, this is the level of documentation you want before you start unplugging connectors.

Source: Original Hirschmann Publication

This is the original Hirschmann publication, P/N 031-300-190-048 Rev B dated 06/25/2009. Hirschmann is the controller manufacturer for Grove cranes. The manual is not a copy or scan – it’s the factory PDF. No aftermarket publisher sat down to ‘rewrite’ the diagnostics. That matters because the step sequences, transducer adjustment tolerances, and fault code definitions come straight from the engineers who wrote the DS350 code. For the TM9100, you want the Hirschmann original.

Frequently Asked Questions

Does this manual cover the engine or hydraulic system?

No. This manual covers only the LMI/DS350 system – not engine or hydraulics.

I’m getting an E18 overload warning but the outriggers are fully extended. What should I check first?

The manual’s step sequence on page 24 starts with measuring voltage at the front outrigger position sensor. If you see 5V reference and 0V signal at full extension, you likely have a sensor failure or wiring short. After that, it tells you to verify the LMI calibration using the boom length percentage and angle data. Do not skip the sensor adjustment procedure on page 42 for the length transducer – if the boom length percentage is off, the LMI will read overload even if the outriggers are down. That specific combination, outriggers down but boom length mis-reported, is a common frustration. The manual anticipates it.

Stop guessing on boom control faults. If you work on Grove TM9100 cranes, get the actual diagnostic document from the people who made the DS350 controller. Access the Factory Manual from AutoRepairManuals. It’s 53 pages, OEM Hirschmann, and it’ll keep you from replacing parts that aren’t broken.
