Electronic device DMU2000 - DMU3000 - DMU3000 PLUS

The purpose of this manual is to provide all the workshops that are part of the assistance network of EFFER cranes with instructions for the use of the new software to run DMU2000, DMU3000 and DMU3000PLUS.

NOTE: The ﬁrst version of load electronic control system ﬁtted to EFFER cranes is called DMU

2000. Subsequently, all the electrical wiring was redesigned, different electrical components were used and the logic to check crane boom uplifting was introduced. The system was named DMU 3000. At the end of the year 2007 the DMU 3000 PLUS was designed and installed as a standard feature on some crane models. This electronic system, unlike the previous ones, also runs the crane maximum operating speed allowed according to load applied to the hook and the geometric conﬁgurations which the crane has when working. Please note that with the interface software DMU Suite 1.3 you can connect all types of DMU devices mentioned above, to edit the preset parameters or diagnostic operations.

To use the program “DMU Suite 1.3” you need a computer with the following minimum system

requirements:

- PC with Pentium 100 MHz processor

- CD-ROM drive

- Microsoft Windows operating system 98 or a more recent version

- Ram 32 MB (64 MB recommended)

- 100 MB of free space on hard disk

- Video card that supports a 800x600 monitor resolution or higher

- Monitor (laptops) 13’’ or higher

- n. 1 Standard free serial port (see p. 8 for more information)

In addition, it requires:

- n. 1 electrical cable for PC connection to DMU (code 9395261 l=10 M)

The following optional items may be supplied:

- n. 1 USB serial port adapter (code 9395668)

The software must be installed on your PC hard disk (portable computer recommended); it is not possible to start the programme directly from the CD-ROM.

1. Introduction

The software DMU Suite 1.3 is a software that should be preferably installed on a portable computer.

The software DMU Suite 1.3 allows managing/changing some of the parameters of the device. These parameters are dened by LEVEL 1, that is available only to Sol.Ge S.p.A. autorized workshops, by entering the correct password.

A special electrical cable is required to connect the crane to the computer. This cable is supplied by Sol. Ge with the software to install on your computer.

It is possible to run the software only after typing a password. In this way it is always possible to nd the

operator that has carried out changes/variation in standard setting parameters.

The password has a deadline: before the date of expiry the new password is communicated only to workshops with which cooperation is established.

N.B.: If an expired password is typed in even by mistake to have access to the software, the software is automatically stopped. In order to use the software again it is necessary to perform a new complete installation of the software on your computer.

NOTE: the DMU 3000 PLUS, unlike the other two types, also runs the radio control speed.

Please note that when the crane is tted with DMU 3000 PLUS the operating speeds are not editable with the software, but it requires an authorization called LEVEL 2 which is reserved for EFFER technicians.

Electronic device DMU2000 - DMU3000 - DMU3000 PLUS

THE POWER OF PERFORMANCE

1 Serial number inside the DMU

The serial number inserted inside the DMU should be the same as the crane one. If the DMU tted to the crane is to be replaced, a new one taken from stock shall be tted. This new device will therefore not include the setting les, then you will have to enter not only these les which are provided by Sol. Ge S.p.A. for the specic crane, but also the crane serial number in the box provided.

2 Pressure 100% basic crane 1st boom cylinder

The rst boom cylinder can have two dierent maximum pressures permitted for the use as basic crane and for the use with additional jib: the setting value shown on the rst line concerns the operation of a basic crane, i.e. a crane equipped with additional jib or that is working without the jib tted. When this pressure value inside the rst boom cylinder is achieved, the load limiting device comes into operation. If a performance downgrading of the basic crane is necessary, due to a problem of stability, (value to be decreased according to practical tests) the load limiting device should be operated rst, by decreasing the value on this line.

3 Pressure 100% basic crane 1st boom cylinder with Jib ﬁtted

The setting value shown on the second line concerns the operation of the load limiting device when the max. allowed pressure value inside the rst boom cylinder is achieved, operating with a crane, that is working with the additional jib tted. If a performance downgrading of the basic crane is necessary, following a problem of stability, (value to be decreased according to practical tests) the load limiting device should be operated rst, by decreasing the value on this line. Reductions of more than 50% of the original values are not recommended: should this necessity arise please contact Sol.Ge S.p.A. technical oce.

NOTE: If a performance downgrading is required in the area of maximum performance for a problem of stability, you can decrease the maximum pressure values inside the DMU, but it is not necessary to reduce also the working pressure in the hydraulic circuit of the crane. When the operating lockout resulting from DMU setting comes into operation, the boom rise movements are still possible, but these movements are automatically interrupted when performance is increased approximately by 10% compared to the set value.

THE POWER OF PERFORMANCE

Electronic device DMU2000 - DMU3000 - DMU3000 PLUS

4 Pressure 100% 2nd boom cylinder

When this pressure value inside the second boom cylinder is achieved, the load limiting device is operated.

5 Pressure 100% additional jib cylinder

When this pressure value inside the jib cylinder is achieved, the load limiting device is operated.

6 % Downgrading 1st boom cylinder to work in B area

By changing this value, you change the crane performance relating to the front work area. Performance is expressed as a percentage of the crane maximum lifting capacity . NOTE: On crane models ﬁtted with an encoder to determine the position of the crane booms with respect to the truck longitudinal axis, zero is displayed instead of the value originally set, and to make a change in performance in B Area, you should use the appropriate software interface called “SERVICE MANUAL, edit stability parameters.

7 Cancel performance downgrading in B area If the installation of the crane does not require any identication of the area “B”, related to performance downgrading, if you select “OFF” you cancel this function. NOTE: We recommend not setting the front working area by 100%, as the load limiting device operation would lead to functional restrictions relating to the manoeuvrability of the crane upper booms

owing to the off selection (e.g. when it comes into operation no rise manoeuvre with the crane booms is allowed). If you must reverse the position of working area “A” with the position of the work area “B”, you must operate mechanically cranes by moving the proximity switches or the cam: this change in

position is not possible using the DMU.

NOTE: Crane models ﬁtted with an encoder to determine the position of the crane booms with respect to the truck longitudinal axis, OFF appears and you cannot change it. In order to cancel performance downgrading in B Area, you should use the appropriate software interface called “SERVICE MANUAL, edit stability parameters“.

Electronic device DMU2000 - DMU3000 - DMU3000 PLUS

THE POWER OF PERFORMANCE

8 % Downgrading 1st boom cylinder for bucket

A control to operate a bucket is tted to the crane hydraulic control bank: we remind you that this control is hydraulically operated after the sequence of two manoeuvres to simulate closing, plus a manoeu- vre to simulate opening are carried out. To return to the standard crane operation you must perform a new start-up procedure of the device. This implies a performance downgrading of the crane, already set at 12%. By changing this value you have a consequent intervention of the load limiting device when the percentage of the performance set is achieved.

9 % Downgrading 1st boom cylinder for CS exchange solenoid valve

An exchange solenoid valve is tted to crane additional jib. This valve has the function to divert oil intended for a function of a crane jib to a bucket. This solenoid valve is operated by means of an electric switch. Each time you turn this switch, a performance downgrading of the crane is operated, already set at 12%. By changing this value you have a consequent intervention of the load limiting device when the percentage of the performance set is achieved.

10 % Downgrading 1st boom cylinder for basket/PLE

If the use of the crane in the PLE function requires a limitation in horizontal outreach for stability problems you can change the load limiting device setting value. This downgrading does not aect the performance of the crane during normal work for lifting loads.

11 % Downgrading jib cylinder for basket/PLE

If the use of the crane in the PLE function requires a limitation in horizontal outreach only of the additional extensions for problems of additional jib load stability, you can change the setting value of the load limiting device connected to jib: this downgrading does not aect the jib performance during normal work for lifting loads.

Electronic device DMU2000 - DMU3000 - DMU3000 PLUS

12 Jib stroke ﬁnal value (Change in end-of-stroke point while additional jib is opening)

A proper setting of electronic angle sensor placed on additional jib makes crane lock not operational when you run a manoeuvre of maximum opening, after the maximum pressure value inside the jib cylinder is achieved. In this case, use the RESET button to retrieve the crane movements. The movement of jib opening should be discontinued by the angle sensor setting by preventing the jib cylinder from achieving its maximum extension, even 0. 5 mm. only. By editing this parameter the electronic end-of-stroke point related to jib opening is moved , thus avoiding stopping crane operation without reason.

Note: Please see page 33 for further information.

13 Disabling stand-by function

On all the DMUs the stand-by function is turned on: after 30 minutes during which the DMU is electrically operated but no movement with the crane is carried out, the electronic part with the highest power input automatically switches o, thus limiting the electric consumption by truck batteries. (To restore full crane operation it is necessary to press the stop emergency button, and after it is released operate the RESET button). Certain operators may nd this procedure complicated, therefore the necessity to cancel the stand-by function may arise. If ON is set in the computer screen, the stand-by function is disabled. If OFF is set in the computer screen, the stand-by function is enabled.

THE POWER OF PERFORMANCE

14 2nd boom safe opening device (ON=2; OFF=100)

You can operate an automatic device which stops the crane opening manoeuvre when the crane is folded behind cab - if the second boom cylinder, on the rod side, has not sucient pressure inside to prevent the second boom from falling down as soon as it releases from the support tted to the column. The crane shall be delivered with the device o (the number 100 appears on the box).

15 Enabling angular sensor to detect 1st boom position

As the anti-bridge function is installed, an angle sensor is tted to the rst boom, and the function must be enabled otherwise the DMU reports an error. Enable is on when the box is selected (tick). NOTE: the DMU emits an output electric signal, according to the position of the crane boom. This signal controls the operation of an alarm, or better, prevents crane stabilizers from rising , when crane boom is in wrong position.

The authorization above is only possible on cranes where the DMU 2000 or DMU 3000 are ﬁtted . On cranes where the DMU 3000 PLUS is ﬁtted, OFF appears next to this indication and you cannot use this function.

16 Winch maximum capacity ( maximum weight )

A value expressed in kg appears next to this indication: this is an indication of the weight on the hook which should not be exceeded when using the winch. Otherwise all crane boom lifting movements and winch lifting movements are automatically stopped. In order to use this function the optional “radio pin” or “winch proportional load cell” must be ﬁtted to the crane. Please note that the value of weight which appears next to this indication is relating to the use of the winch in one-cable lifting conﬁguration (direct pull).

17 Detecting winch load with load cell ( enverr )

Depending on the type of crane, and the type of winch ﬁtted, it may happen that instead of the traditional “torque limit”, a proportional load cell is ﬁtted to the same winch to limit the maximum capacity of the load applied to the hook. In these speciﬁc cases, you get crane good operation if ON appears next to such indication. If off appears the crane is inoperative.

18 Detecting pin load on winch (enperno)

Depending on the type of crane, and the type of winch ﬁtted, it may happen that instead of the traditional “torque limit” a proportional load cell is ﬁtted to the hook connecting pin to limit the maximum capacity of the load applied to the hook . In these speciﬁc cases, you have the good operation of the crane if ON appears next to the indication. If off appears the crane is inoperative.

19 Enabling load reading with radio pin on winch or hook ( enpeso )

The cranes which are not provided with the function described in paragraph 17 or 18 a pin for the junction of the hook to the crane can be installed - always as an option - with a proportional load cell at its interior, with which it is possible to have an indication of the value of the load applied to the hook. This value can be read on the display of the radio pushbutton panel. To use this function, ON should appear next to the indication. Off disables the function.

8. Displaying/changing available data in the software

a) DISPLAYING

To display and change the data in the DMU tted to the crane it is necessary to:

u Click on the icon “Current Crane”

u Click on the icon “Display/Change

DMU Data Sheet”

- The software runs the data uploading inside the DMU on the computer. You must wait a few seconds to run the operation.

- “DMU Data Sheet” window appears

In column A on the left, the maximum setting values allowed for this project are shown, while in the column B the set setting values are shown.

Why are the maximum pressure values higher than setting values???

The setting values ensure that the crane is able to handle the loads indicated in the load diagrams with an “ideal” hydraulic system, i.e. with values of back-pressure on oil exhaust pipes almost close to zero: If this is not found on a specic installation, you can raise the values in last column up to the maximum values allowed. Thus the DMU device delays its operation, and the crane increases its performance. As to the setting value for the work in front of the cab, (rst boom downgrading in B area) the setting value that appears is the value resulting from the application of the crane to the truck, which is the minimum possible in respect of the weights on the axes only: in case the specic truck allows operating in conditions of stability with higher performance, you can change this value, i.e. increase it.
