Special Instructions About the 8215/8225 Laser Fixtures

Caution!

Prior to mounting the laser alignment ﬁxtures on machine shafts, all

switches operating the machines should be “locked out” (follow lockout

procedures for your facility). After an alignment has been completed,

the work area should be inspected to ensure that all equipment is clear

of rotating shafts and couplings, prior to removal of the lockout protec-

tion.

Caution!

The 8215/8225 Laser Alignment Fixtures use a Class II (CDRH)

laser or Class 2 (IEC) laser. This laser complies with 21 CFR

1040.10 and 1040.11 safety requirements with a power output < 1.0

mW (average) and a pulse repetition of 600 pulses/sec. The pulse

duration is <110 microseconds. However, do not expose the human eye

directly to the laser beam! Warnings are located on each sensor head.

Caution!

Using the controls or adjustments in ways other than speciﬁed in this

documentation may result in hazardous laser radiation exposure.

Making the hardware, ﬁrmware, or software perform in ways other

than speciﬁed in this documentation may result in hazardous laser

radiation exposure.

Note Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of this device. Note This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.

General Description Sensor Head Description The sensor head with the laser source on top is the “Master” head (known as head “A”). The other head is the “Slave” (known as head “B”). The model number is listed on the back of each head. They can be identiﬁed by the letter A or B on the front. The difference between the Model 8215 sensor heads and the 8225 sensor heads are the target (PSD) size, laser distance, and the front overlay.

LED Status Green Yellow X X (flashing) X General Description Meaning Required Action Red Normal Operation - When the Laser Head systems are all functioning properly and the laser beam from the companion Laser Head is striking the PSD in the linear region. This is the desired state. The Laser Head is in the acceptable condition to perform an alignment.
PAGE 6
LED Status Green Yellow Meaning Required Action Red X (flashing) Low battery 1st warning (sensor head) - The Laser Head has the ability to monitor its own battery power. The battery power is checked periodically to determine if it is below the minimum acceptable power. When the battery power reaches 4.8 volts, the LED will be flashed off for 0.5 sec. and then flashed on for 0.5 sec. Data is accepted when the battery is this state. Recharge sensor heads.
PAGE 7
LED Functionality Difference Due to Dual Pass mode The functionality of the LED differs slightly from the states described in the above table when the Dual Pass mode of operation is selected. The difference lies in the LED state when the companion Laser Heads laser beam is on the PSD. In Dual Pass mode, when the laser beam is on or off of the PSD the LED will be a solid yellow, EVEN WHEN THE BEAM IS IN THE LINEAR PORTION OF THE PSD. The beam will then ﬂash to green whenever a valid data point is acquired.

General Maintenance Additional maintenance information is located in Chapter 10. Care and Handling To ensure satisfactory service from this system, follow these procedures: • Keep the mounting base and chain mounting posts lightly oiled to prevent them from corroding. • To maintain repeatability and accuracy, avoid dropping ﬁxture items. Refer to the Customer Assistance section for repair, update, and calibration. • Do not subject system items to large temperature swings.

Battery Charging Batteries may be charged with the Model 8211 or the Model 8212. The Model 8211 is a “smart, drop-in” charger that can provide a fast- or tricklecharge for the laser heads and analyzer. In fact, it can discharge the laser heads, if necessary. The Model 8212 is an “overnight” trickle-charger that can only trickle-charge laser heads and the analyzer. Model 8211 Smart Charger The Model 8211 provides all battery charging needs and comes with the system.
PAGE 10
To set up the 8211, complete these steps: 1. ··· Plug the power cord into the power supply. 2. ··· Plug the power cord into an AC receptacle. 3. ··· Plug the power supply into the 8211 in the top end cap. At that time, the beeper will sound indicating that power has been applied to the battery charger. As a test, all LEDs will illuminate for 1.5 seconds. 4. ··· Plug the analyzer charging cable into the bottom end cap.
