Cable length of 12 m Pedant control box with variable speed on both table rotation and tilt forward/stop/reverse. Potentiometer and digital display in RPM. Cable length of 12 m Foot control pedal for control table rotation forward/stop/reverse Protection class IP54 against dust and heavy rain on electric control box and motors Tilt Brake and Safety Devices Two self-lock worm gears are used in the tilt gearboxes so that when the motor is running the gears lock and do not allow the slewing bearing to tilt. Two electric brakes are used in the tilt motor so that when the motor are not in used the gearboxes do not rotate. The air cylinder tilt brakes (SG1 & SG2) supports the slewing bearing if there is a gear or gearbox failure. The tilt brake can be applied manually through the main control box or automatically through the PLC if there is a gear or gearbox failure.

6 5. All the cables coming from the positioner are directed to the main control box. Each cable directed to the main control box is marked with a designated number. Match and connect the marked cable in the main control panel circuit. The electrical wires are placed through the inside structure of the positioner. Note: L1, L2 and L3 are designated terminals for the main power. 6. The electric diagram is attached on the back of the main control box panel door. Ensure the system is properly wired and powered as per its electrical diagram and data plate. CWP 40 Electrical Diagram 7. The tilt limit switch comes pre-installed. Ensure that limit switch and limit switch stopper are making proper contact. Place the limit switch cover and fix it to the positioner frame using four bolts. 8. The tilt brake magnetic contactor located at the bottom of the hydraulic air actuator comes preinstalled. Ensure that the magnetic contactor is properly fixed to the hydraulic air actuator. Place the magnetic contactor cover and fix it to the positioner frame using four bolts. Page # 6

9. Connect compress air supply to the tilt brake air regulated. The air pressure should be set to 70-145 (psi).

Ensure the air tubes supplying air to both tilt breaks (SG1 & SG2) are properly connected in accordance to

Ensure that the left and right tilt break sensors sw1 are properly fixed in their brackets. 12.

7 9. Connect compress air supply to the tilt brake air regulated. The air pressure should be set to (psi). Ensure that there is air supply available at all times during the positioner operation. 10. Ensure the air tubes supplying air to both tilt breaks (SG1 & SG2) are properly connected in accordance to their labelled numbering system. 11. Ensure that the left and right tilt break sensors sw1 are properly fixed in their brackets. 12. Ensure that the welding positioner maximum eccentricity and gravity center are not exceed when placing the work piece. Use the capacity chart and data plate as reference. CWP 40 Capacity Chart CWP 40 Data Plate Page # 7

13. If the work piece used weights less than 2 MT and has a GC

The ground clamp for the positioners is rated for 1000 amps.

can damage and reduce the bearings life. 15.

8 13. If the work piece used weights less than 2 MT and has a GC < 600 mm the supplied counter weights need to be placed on top of the left and right end beams. If the work piece has a GC > 600 mm the counter weights need to be removed. When there is no work piece on the positioner the counter weights are removed. Each counter weight is fixed by using two removable pins. 14. The ground clamp for the positioners is rated for 1000 amps. It can be access by removing four bolts located on the center of the octagonal table. The welding positioner must not be grounded directly since it can damage and reduce the bearings life. 15. Connect the remote control box or the pendant control box to the main control box. There is a single input for this controllers on the main control box located on the far bottom left. Note: only one controller can be use at a single time. Page # 8

10 Remote Control Box Operation Function SPEED r/min SPEED T / R FWD STOP REV Description Digital display screen that indicates current table rotation and tilting speed Potentiometers used to control the table rotation and tilting speed Toggle switch used to change between T: tilting or R: table rotation When T/R switch is on T or R activates tilt or table rotation forward function Stop FWD or REV function When T/R switch is on T or R activates tilt or table rotation reverse function WARNING! When switching from FWD and REV always press the STOP button first and let the table rotation or tilting come to full stop. Failure to do so will cause permanent motor or reducer damage. Main Control Box Operation Function LAMP TILT ROTATION LOCK ALARM POWER OFF POWER ON MANUAL TILT LOCK RESET Description When POWER ON the indicator lamp lights up When the remote control toggle switch T/R is set to T the indicator lamp lights up When the remote control toggle switch T/R is set to R the indicator lamp lights up This indicator lamp lights up if: a) MANUAL TILT LOCK toggle switch set to I b) The tilt lock automatically activates (see Tilt Brake section for more details) This indicator lamp lights up if there is an error or failure with the N2 VFD Off Power switch On Power switch Toggle switch used to manually lock and unlock tilt brake; I: activates tilt brake, O: retracts tilt brake Use to reset main control box in case of N2 VFD failure Note: The tilt brake must always be set to the lock position unless the tilting function is being used.

2) Automatically: in case of a tilt gear train failure or gearbox failure the tilt brake automatically activates Sensor sw1 measures the elapse time t1 between the teeth of gears M128 The sensor sw1

11 Tilt Brake The welding positioner comes equipped with two tilt brakes SG1 and SG2 that can be activated manually or automatically. 1) Manually: through the use of the main control box MANUAL LOCK toggle switch O/I. The tilt brake must always be set to the lock position unless the tilting function is being used. 2) Automatically: in case of a tilt gear train failure or gearbox failure the tilt brake automatically activates Sensor sw1 measures the elapse time t1 between the teeth of gears M128 The sensor sw1 is control by PLC FX1N-24MT located in the main control box The logic is accordingly: if 0 < t < t1 normal working operation the tilt brake stays in unlock mode if t>t1 failure with tilting gear train or gearboxes; the tilt break will activate and hold gear M141 in place. The tilt brake will only activate if the elapse time failure occurs three times (meaning t>t1 occurs in three teeth) Page # 11

If there is a failure in the tilting gearbox M120 or/and M122 and the PLC activates as explained in PLC logic section. For safety reasons the tilt brake will only be removed by resetting the PLC.

12 If there is a failure in the tilting gearbox M120 or/and M122 and the PLC activates as explained in PLC logic section. For safety reasons the tilt brake will only be removed by resetting the PLC. This can be done via connecting the jumper wire to the PLC reset terminals at the same time (COM,X11) while holding the terminals the tilt brake will begin to draw back. Once the tilt brake has been fully drawn back the indicator light in the PLC X13 and X14 will light up. At this point the PLC has been reset. Ensure that the reason for the failure is properly diagnose before operating the equipment again. The logic of the PLC can be tested to ensure the safety tilt brake is working properly as following: Remove both sw1 from their bracket. Ensure the tilt brake is set in the unlock position. Change the VFD function F10 = 0 see Procedure to Re-Setting VFD (N2-200/400) for more details. Place the remote control toggle switch on the tilt function. Quickly move one sw1 sensor against a piece of steel the led light should flash red. Do this three times. Both tilt brakes (SG1 & SG2) will automatically lock. In order to retract the tilt break the PLC must be reset manually as explained earlier. The same is process is done to the second sw1 sensor. Page # 12
