Kato SR-700L, MS-200 Service Manual – Factory Diagnostic Procedures

If you’re a field mechanic working on Kato cranes, you already know the MS-200 multivision display and SR-700L chassis can throw you into a loop when the diagnostics don’t match the real machine. The wrong outrigger setting or a misunderstood service mode screen costs hours of head-scratching. I’ve seen guys skip the serial number programming step and then wonder why the crane refuses to extend. This Kato SR-700L, MS-200 Service Manual keeps that nonsense off your workbench. 73 pages, straight from Kato’s engineering – not a reprint or a generic scan.

73 Pages of OEM Diagnostic Logic

This manual isn’t a repair novel with exploded views and torque tables for every bolt. It’s a focused service and adjustment guide for the MS-200 control system paired with the SR-700L crane. You’ll find exactly what the factory techs use when they run service mode checks. Chapter 7 covers inputs in service mode. Chapter 8 describes the service menu screen layout. If your boom length sensor is off, Chapter 15 walks you through three-point adjustment and zero adjustment. Each procedure references the actual menu screens – no guesswork.

Service Menu Navigation – What the MS-200 Tells You

Chapter 8 is worth the price alone for guys who haven’t memorized the MS-200 menu tree. The manual shows you each service menu screen, what each parameter means, and which switches trigger those inputs. You’ll learn how to access adjustment data (Chapter 11), check software codes (Chapter 10), and pull crane operation records (Chapter 12). When the display throws an error, Chapter 33 gives you the error record list. That’s the kind of specific data that gets a crane back on the job fast.

Set the Crane Serial Number Correctly

One of the most skipped steps is programming the crane serial number and outrigger type into the MS-200. Chapter 9 covers both – section 9-1 for the serial number, 9-2 for the outrigger type. If you swap a main body board and forget to set these, the crane won’t recognize its own configuration. The manual gives you the exact sequence through the service menu. Miss this step and you’ll be chasing phantom communication faults.

Checking Slew Angle and Outriggers – Page 26 Reference

Outrigger problems shut down a lift faster than anything. Chapter 17 splits into checking the slew angle (section 17-1) and checking/adjusting the outriggers (17-2). Page 26 of this manual holds the procedure for verifying slew angle accuracy and outrigger stroke limits. You get the factory pass/fail criteria – not a third-party suggestion. Use page 26 to confirm your outrigger sensor alignment before you trust the load indicator.

Why Trust the Factory Service Manual?

I’ve watched guys waste a full day with aftermarket capacitor timers because the generic manual had the wrong resistance values for the proportional valve outputs (Chapter 22). This Kato document comes from the original manufacturer. Every communication check – COR-ACS (Chapter 24), display to main body (25), main body to top terminal (26), and main body to PC (27) – is written by the engineers who built the system. If you’re serious about crane electronics, you don’t rely on photocopied reprints. You need the real Kato Service Manual with the part number 307431 stamped on it.

FAQ

Does this manual cover both the SR-700L and MS-200?

Yes. The title says SR-700L and MS-200. The MS-200 is the multivision display unit with voice alarm; the SR-700L is the crane model. Both are covered in the same 73-page document.

What is the publication year?

Not listed in the file data. The OCR metadata shows no year. But the content matches late-2000s Kato service logic.

Can I use this manual for the SR-700LS or other Kato models?

Only for SR-700L and MS-200. The procedures for serial number setting, outrigger types, and communications apply specifically to these models. For the SR-700LS, see KATO SR-700L SR-700LS Service Manual.

How do I access the service mode on the MS-200?

Chapter 7 lists the inputs needed. The manual shows which switches to press at power-up and what each service menu screen displays. Follow the sequence exactly to avoid locking up the controller.
