Siemens 840d maintenance manual

If they do, this will eventually defeat the purpose of the pad. The top of the felt, if used, should be sealed with a caulking compound to prevent oils and coolants from penetrating the ground. Do not expose the machine to direct sunlight, or any other heat source. Do not place the machine in an area that will expose the machine to moisture, standing water, liquid or rain.

Air pressure required: psi before regulator, 80 psi after regulator, 15 scfm stan- dard cubic feet per minute momentary. The distance from the air compressor and number of machines attached should be taken into consideration when determining the size of piping for the main air supply line.

Improper grounding will result in a wide range of hard-to-diagnose problems in communica- tions, positioning, spindle motion, etc. The grounding conductor shall be of copper.

The material selected shall be 2. The other end shall be effectively bonded to a copper cold water pipe that is in direct contact with the earth for 10 feet or more See Figure Bond Grounding Conductor to Copper Cold Water Pipe. Record these readings. Voltages should be OV to. Voltages AC or DC across the ground wire will cause false resistance readings. If the ground voltages with VMC off are 0. The number and size of conductors in any raceway shall not be more than will 2.

The conduit must allow ready installation or withdrawal of the conductors without damage to the conductors or to their insulation. Remove the strapping material from the front doors. At this point the VMC is ready for power and air connections. Verify the Main Power Fuses Siemens requires 3 phase power. Voltage must be or Volts depending on Module. Find the part number on the board. Measure the input voltage to the machine on the chart Measure leg to leg the input power lines to the machine.

However, Fadal does not recommend the use of rotary phase converters. All calibration and squareness performed on the assembly line is done with the machine leveled.

It is important to follow the sequence below precisely to ensure proper results. Place the level on the right hand way the outer right hand way on the of the base with the small bubble towards the column.

Take an accurate reading. See Figure Leveling Box Way. Figure Leveling Box Way. Verify the spindle tram and, if necessary, adjust by slightly changing only the two front leveling screws. Larger machines need to be clamped to the floor to prevent movement between the machine and the floor, and clamping holes are provided on all base castings for this purpose.

Even though reinforcing cover used on the optical fiber code has enough mechani- cal strength, be sure not to be damaged by heavy materials drop.

Loosen both coupler HUB screws. Figure Gages 7. Carefully remove shipping crate, with pendant inside, from machine and place it close to the right side of the machine. Remove second smaller box from the machine. Place the chip conveyor in the coolant tank. Measure the height to the top of the conveyor sheet metal should be approximately the height of the coolant tank. Set the machine height the machine should be on the small leveling pads to slightly above the height established in step 2 above.

Adjust the machine height during leveling and installation to minimize the gap or overlap between the coolant tank face and the machine sheet metal, Figure Minimize Gap of Overlap.

Figure Minimize Gap or Overlap 8. The control also has a variable speed control for the belt speed. The belt speed can be controlled from 2. Check air pressure: Right regulator psi. Tool Out Only. Left Regulator psi. Check way lube level. Grease Geneva wheel and gear using Kopr-Kote. For high torque machines, check fluid level in the hydraulic actuator reservoir. Inspect all cooling fans, clean screens if necessary. Remove the oil line that is between the way lube pump and the three port junction T that is located near the pump mount.

Verify that the flush pump air regulator is fully counterclockwise. Attach an air line to the flush pump. Verify that the air regulator is closed. Wear safety glasses! If the fan is turning slowly or not at all, it may require cleaning or replacement. The fan on the bottom of the junction box has a screen that requires periodic inspection and removal for cleaning. Visually check the fluid level with the machine powered on. It is very important to grease all moving parts of the tool changer at least once a week.

Floating interfaces to the machine not accessible to the end user. Floating signal interfaces directly accessible to the end user e. For these interfaces, you must always make sure that there is either safe isolation with respect to the line supply voltage or that there are two basic insulation levels, for V AC each. The individual system components are:. S Distributor box and handheld unit. The individual modules are attached to a metal cabinet panel by means of screws.

Make sure that near the screws a low-impedance contact of the NCU box with the cabinet wall can be made. Insulating paints at the contact point must be removed. The ground and module ground M should be connected at the power supply terminal of the IM In addition to the protective grounding of system components, special precautions must be taken to ensure safe, fault-free operation of the system. These measures include shielded signal cables, special equipotential bonding, isolation, and shielding measures.

To ensure safe, interference-free operation of the installation, it is essential to use the cables specified in the individual diagrams. For digital signal transmission, the shield must have a conductive connection at both sides of the housing. Standard shielded cables grounded on only one side can be used for devices from other manufacturers printers, programming devices, etc. In order to achieve the best possible noise immunity of the complete system control, power module, machine , the following EMC measures must be carefully observed:.

S Signal cables and load cables must be routed at the greatest possible distance from one another. S Only cables provided by the manufacturer should be used as signal cables from and to the NCU. S Signal cables may not be routed close to strong external magnetic fields e. S If signal lines cannot be routed a sufficient distance away from other cables, they must be installed in grounded cable ducts metal. S The clearance interference injection area between the following lines must be kept to a minimum:.

For further notes on interference suppression measures and the connection of. Backup batteries must only be transported in the original packaging. No special authorization is required to ship backup batteries. The lithium content is approximately mg. The backup battery is classified as a hazardous substance, Class 9, in accordance with the relevant air-freight transportation regulations. Incorrect handling of backup batteries can lead to a risk of ignition, explosion and combustion.

The stipulations of EN , in particular regarding avoidance of mechanical or electrical tampering of any kind, must be complied with. When working in areas where gases, dust and oils may be hazardous to functionality, the controller must be operated in a control cabinet with a heat exchanger or with suitable supply air.

The user must consider interference radiation for the complete system. Particular attention should be paid to cabling. Please contact your sales representative for assistance and support. If compliance with limit class B residential areas is required, please contact your local Siemens office or sales representative. The bus line must be terminated at both ends. To do this, enable the termi-. S Only two inserted terminating resistors are permitted. At least 1 terminal must be supplied with 5 V.

This is done by connecting an MPI connector with the terminating resistor connected to an energized device. Drop cables feeder cable from bus segment to node should be as short as possible.

Every MPI node must first be connected and then activated. When disconnecting an MPI node, first deactivate the connection and then remove the connector. Another possibility is two identical components, provided they have different node addresses. No bus terminating resistors may be inserted at the distributor boxes of an. Welcome to ManualMachine.
