Operating instructions torque meter for power take off (PTO)-Version 1.0

These assembly instructions are intended for the following products: - 75 mm long measuring shaft for fitting to a PTO shaft (drawing numbers MP01-40 90 02 01, MP01-40 90 02 02 or MS093-40 30 02 99) - Customised variants of the above-mentioned measuring intermediate shaft These instructions must be used in conjunction with the manual for the ‘VETAS 3’ evaluation unit and the ‘VECTO’ configuration software.

2 Safety instructions The operating instructions must be read carefully before commissioning, maintenance or any other work on the torque measurement system. Compliance with all safety instructions and safety regulations for the attached equipment is a prerequisite for the safe and proper handling of the device. Only qualified personnel may carry out maintenance work on electrical components. These safety instructions must be included when the torque measurement flange is sold. • Wear safety footwear and gloves during assembly, transport and maintenance. • Tighten the rotor screws to the specified...

• Store in a dry, dust-free place • Do not expose to corrosive substances • Protect from direct sunlight • Avoid mechanical shocks • Storage temperature as per the data sheet If the system breaks, there is a risk of fatal injury from flying parts. • Limit torque (exceeding this will cause deformation of the system and consequently lead to permanent measurement errors), • breakage torque (exceeding this leads to dangerous failure of the system), • limit values for rotational speeds, • limits on electrical load capacity. These limits are specified in the product data sheets. Operating instructions...

- A rotor fitted with strain gauges for measuring torque. - A toothed ring on the rotor with X pulses per revolution for measuring the rotational speed. The number of pulses depends on the system and can be found in the data sheet and the test report. - Stator with bearing, permanently mounted to the rotor. - A flexible shaft sleeve extending from the stator to protect the signal cables and the power supply cable. - For contactless measurement technology in the rotor, the following is provided between the rotor and the stator: o a wireless power supply (inductive) and o a wireless signal transmission...

The torque meter is fitted between the tractor’s drive shaft (tractor side) and the harvesting implement to be connected (tool side / implement side). The bolts and tightening torque specified below (see 3.1.2) must be used for installation. The flange housing acts as the stator. The receiving electronics are installed there. The housing must be secured against rotational movement as far as possible, as this affects the speed signal. The eye bolt (eye bolt for stator mounting) can be used for fixing. Axial movements, for example when the vehicle’s axles compress, must be taken into account. The...

Table 1: Tightening torques for system MP01-40 90 02 01 The torque signal can be measured as Signal 1 via the VETAS outputs ‘X956 Analog out 1’ and ‘X958 Freq out 1’ (see Figure Figure 1). The speed signal can be measured as Signal 2 via the VETAS output ‘X959 Freq out 2’ (see Figure Figure 1). If, for example, the torque is to be measured as an analogue voltage, an adapter cable (see 3.2.2) can be connected to X956. If, for example, the rotational speed is to be measured as a frequency, an adapter cable (see 3.2.2) can be connected to X959. Operating instructions torque meter for power take...

Figure 1 Rear view of VETAS3 Three cables extend from the torque sensor, which are bundled together in a flexible conduit. The flexible conduit must be secured to the vehicle after the flange has been fitted to prevent the cables from becoming tangled or wrapped round anything. Nevertheless, possible movements of the vehicle and the axles must be taken into account here. If the flexible conduit is secured without sufficient play, there is a risk of the electrical cables being torn off. ATESTEO Operating instructions torque meter for power take off (PTO)–Version 1.0

The three cables are plugged into the VETAS 3 at their far end. This connects the evaluation unit to the measuring system. Signal transmission and power supply are established. Please refer to the VETAS 3 manual for details of the VETAS 3 power supply. 3.2.2 Pin assignment (data cable) If a data cable (Article code 10004468) has been ordered, this connects a BNC output on the VETAS 3 to the customer’s measurement equipment. The customer has fitted the Phoenix Contact connector 1693416. It has the following pin configuration: Table 2: Pin assignment for adapter cable Operating instructions torque...

Switch off the VETAS evaluation unit and disconnect it from the mains supply. For maintenance purposes, the three water drain screws can now be removed (seeFigure2). The sensor can then be rinsed out with clean water. All three drains should be flushed through one after the other. Before recommissioning, the three drains must be resealed using the screws supplied. If the system is stored for a longer period, flushing and drying for 48 hours is recommended. Once dry, the drains should be sealed. The system can then be put into storage. ATESTEO recommends having the torque measurement technology...
