For maximum safety, the battery charger has a “Pending” status LED, which lights momentarily when the head is first placed on the charger. If a battery is very low, or is out of a specific temperature range, it cannot be safely charged. When this condition occurs the “Pending” indicator remains light. While “Pending,” the charger is actually charging the batteries at a very low rate. This brings the low battery into acceptable voltage range.
After the “Discharge” cycle has completed the charger automatically begins fast charging and the “Fast” indicator light turns on. To avoid the battery memory concern, use the “Discharge” mode when you have more than 20 minutes to charge the sensor head batteries.
“Pending LED” will light momentarily and switch into FAST charge. Charge time for a fully discharged set of batteries is 15 minutes. The beeper will sound when both heads are fully charged and have switched to TRICKLE charge. To avoid the NiCad battery memory concern, use the DISCHARGE mode when you have more than 20 minutes to charge the sensor head batteries.
Model 8212 Trickle Charger The Model 8212 battery charger is a trickle charger for the laser heads and the Model 8117 UltraSpec analyzer. It will charge the laser heads and analyzer in ten hours. This is intended to be an overnight charge. The laser heads should not be left on charge over 24 hours. Continual overcharging the batteries will result in a shortened life. To set up the Model 8212 charger, complete the following steps: 1.
Charging the Model 8117 and 2120 Analyzers with the Model 8212 Charger After plugging the charging cable (A821102) into the 8212, plug the other end of the cable into the charger connection on the top end cap of the Model 8117 or the Model 2120 analyzer. Ensure the LED on the analyzer illuminates, if applicable. The Model 8117 battery pack will recharge in 14 to 16 hours. If the batteries are allowed to continually remain on charge for longer than 16 hours, battery degradation will occur.
Battery Usage - Laser Heads A rechargeable battery pack is used to power each sensor head. A fully charged battery pack will give 3 to 4 hours of continuous service while transmitting data. Longer operation is possible since typical alignments do not require continuous communication with the analyzer. The battery is designed to have a long life and is not intended to be replaced by the user. Replacement should be performed only at CSI.
Precautions Please follow these precautions carefully. Any product damage due to these conditions may void the warranty. • Do not change the battery pack with the battery charger connected as damage may occur to the analyzer. • Use only CSI-supplied battery chargers that have been approved for use with UltraSpec analyzers and Model 8215/8225 laser heads. The use of any other charger will most likely damage the equipment.
Introduction to Laser Alignment Fixtures Setup This section takes you through a step-by-step setup of the UltraSpec 8215/ 8225 Laser Alignment Fixtures. Before performing alignment, be sure all pre-alignment checks have been completed. Caution! Prior to mounting the laser alignment fixtures on machine shafts, all switches operating the machines should be “locked out.” Follow safety precautions for your facility. Normally, only personnel performing the alignment should be able to “unlock” any startup switch.
Attaching the Fixtures This section shows how to attach and secure the mounting base, chains, align the two mounting bases by leveling, install the sensor heads, turn on the sensor heads, and center the lasers on their targets. Attaching Chain to the Mounting Base Select the chain tightener of choice. The left photograph shows a standard hex nut which should be tightened with a 9/16 inch wrench. The right photograph shows a knurled nut which can be tightened by hand.
Attaching Chain to the Chain Pickup This photograph shows how the chain attaches and actually clamps the shaft. After slipping a chain link into the chain pickup, tighten the bolt at the end of the chain.
Allowing Maximum Tightening Range To allow for maximum tightening range, ensure that the chain nut is flush with the end of the chain bolt (as shown by arrow). Notice that the chain bolts are on opposite sides. As shown in later sections, each mounting base can be installed on either end and the chain bolts placed on either side of the shaft.
Positioning a Mounting Base Tighten one of the mounting bases and rotate it (along with the shaft) until it is somewhat level at the top of the rotation. To tighten the mounting base, use a 9/16 inch wrench or your hand, depending on which chain tightener is being used. Caution! Do not overtighten the chain – the maximum tightening torque is 10 ft.-lbs.
Positioning the Other Mounting Base With the previous mounting base still in its level position, if necessary, loosen and rotate the other mounting base until it is somewhat level with it. Tighten this base and recheck the other base to ensure that both bases are now level with each other. Although this part of the procedure is not absolutely critical, placing the mounting bases relatively level with each other allows the laser beam adjustment to be more or less centered.
Attaching Excess Chain One of the problems with using chains as a mounting bracket is that the excess chain flops and can cause errors. UltraSpec laser alignment fixtures provide solutions for this problem. Two slots are provided (one on either side) to take up the slack. As shown in the following photographs, you can use either or both of the slots as needed. The order of use is not important. In fact, the L-slot cannot be used when mounting to shafts (or couplings) greater than 3 inches (76 mm) in diameter.
Using the L-shaped Slot Caution! Do not attach excess chain prior to tightening the mounting base chain bolts. Doing so may cause damage to the L and T-shaped slots.
Using the Chain Clip You will almost always have a little extra chain left over. In that case, use the chain clip to attach it to the previous chain loop. CSI recommends that you use this clip to help prevent the chain from sliding out of the L-slot as the shafts are rotated.
Installing a Post Screw a post into each of the outer holes in the mounting base. Tighten each post with the supplied tightener (Phillips screwdriver) or with a 1/8 inch Allen wrench (not supplied with kit).
Mounting a Sensor Head Note Head A and B are identified with letters on the front panel. Place a sensor head on the two posts. It does not matter which side of the coupling Head A or Head B is mounted on – the heads will be configured in the analyzer. Adjust to desired position and tighten each post clamp finger tight. The vertical posts allow up to 1.5 inches (38 mm) of vertical adjustment. If more vertical adjustment is needed, use the vertical extension blocks.
Depending on the clearance around which the laser head will be rotated, the position of the RF antenna may have to be adjusted. When the antenna is in its most upright position it extends up above the top of the laser head. Holding the antenna housing (not the antenna itself), rotate or twist the antenna down (or up depending on its starting position) to its desired postion. The antenna’s rotational arc is 30 degrees.
Mounting the Other Sensor Head Install the opposite sensor head in the same manner (Head A or Head B, depending on which sensor head was mounted on the other side).
Connecting the 8000RF Interface Attaching 8000RF to RS232 25-pin Serial Port Attaching the Fixtures 4-31
Install the 8000RF Interface onto the RS232 serial port of the UltraSpec analyzer by completing the following steps: 1. ··· Ensure that the UltraSpec analyzer is turned off. 2. ··· Connect the 8000RF Interface to the RS232 25-pin connector to the UltraSpec analyzer. 3. ··· Turn the UltraSpec analyzer on. Note The RF antenna on the 8000RF Interface does not rotate or twist. Therefore, trying to rotate or twist the antenna will only result in damaging the 8000RF Interface.
Starting the UltraSpec Analyzer Turn on the UltraSpec analyzer by pressing the ON/OFF button located at the top right of the Front Panel. This automatically takes you to the program’s main menu. From the main menu, press the Options key. Select (4) Alignment Setup and press Enter. From the Alignment Setup menu, configure the alignment parameters. (Refer to “Alignment Setup” on page 3-6 for details.
Foot Pre-Check – Soft Foot Quick Spec – No When finished, press Enter to accept any changes made. Finally, press the Reset/Main key to return to the program’s Main menu.
Communication Between the Fixtures and Analyzer The UltraSpec analyzer conducts communication with the fixtures via a short-range, low-power radio frequency (RF) carrier or by cable. Communication – With RF, communication occurs in much the same manner as with other short-range wireless systems (e.g., cordless phones) – a direct line of sight communication is not required.
There may be times when an RF communication between each sensor head and the UltraSpec analyzer is not convenient. Moving or keeping the analyzer closer to the laser heads can minimize this inconvenience. The sensor heads have memory for saving alignment readings. If communication with the UltraSpec analyzer is broken during rotation (while using the Auto Sweep mode), these readings are stored in memory until they can be transmitted. When the sensor head is turned off, the memory data is erased.
Direct Connect Direct Connect is designed for those conditions where it is difficult to communicate between the analyzer and the sensor heads using RF. Conditions such as building construction materials and contents, other radio systems operation in the vicinity at or near the same operation frequency, and noise generated by nearby equipment may make RF communication unsatisfactory. To use Direct Connect, complete these steps: 1.···· Make sure the UltraSpec analyzer is turned off. 2.
Note When connecting the Lemo connector to its mating connector, line up the red dots located on each connector with each other before completing the connections.** 4. ··· Connect the Lemo connector on the opposite end of the extension cable to the Lemo port under the nose of each 8215/8225. Note When connecting the Lemo connector to its mating connector, line up the red dots located on each connector with each other before completing the connections.
2 Caution! When using any cable connector inside the sensor head connector, DO NOT turn or twist the connector. This will shear the cable pins off (inside the connector) totally disabling the sensor head and cable. Pull the cable connector completely out of the sensor head connector before turning the cable.
The extension cables are 10 feet (3 m) long. With the connection pigtail, the total length is 12 feet (3.6 m). When standing between the sensor heads, a 20 feet (6 m) span can be aligned. Extension cables are available for longer spans or, if you cannot stand directly in the middle. UltraSpec Analyzer Note With the 8215, a maximum distance of 30 feet between the laser heads can be achieved. With the 8225, a maximum distance of 100 feet between laser heads can be achieved.
