When auditing the headlamp, the arrows indicate if the lamp is within or out of allowable limits of +/- 4 inches.
2.1.5 BATTERY CHARGER SOCKET
The HBA 5 is powered by an internal battery supply that will provide a sufficient amount of power
during working hours. An 110V ac power supply adapter is provided with the system for charging. A
red LED light labeled “Charge” lights up to inform the operator that the battery is receiving power and
is charging.
2.1.5.1 BATTERY PACK
The HBA 5 internal battery is located on the inside of the alignment head. During initial assembly, battery pack must be installed per STEP 9, Assembly
Instructions. The battery pack is detachable and can be removed if determined that it can no longer be recharged. Only certified battery packs as
determined by SYMTECH Corporation can be substituted for the original, any unauthorized replacement risks voiding all warranties
2.2 ALIGNMENT HEAD
2.2.1 OPTICAL LENS
The lens on the HBA 5’s alignment head is an impact resistant Fresnel lens designed
specifically to converge the light emitted from the headlamp onto the internal screen. The
pattern of light as seen on the screen is representative of the lamp pattern, as it would appear on
an alignment screen at 25 feet away in a laboratory situation.
2.2.2 POSITION SENSORS
The four position sensors are located on the front of the lens assembly, and are
used to centrally locate the headlamp in front of the HBA5. These sensors send a
signal, which is seen on the lamp position indicator arrows while in the position
check mode.
2.2.3 LEVEL VIALS
The level vials (2) are used as a field calibration reference only, and should not be tampered
with. They are located inside the optical block. The level vial located at the bottom of the aim
screen is used in conjunction with the front eccentric axle to adjust the level from left to right.
The level vial located at top of the head, closest to the viewing window, is used in conjunction
with the rear eccentric axle for field laser calibration and verification.
2.3 MAST
The Mast is used to hold the HBA5 head and mirror assembly. It is attached to the base using a 1/2” diameter stud bolted through
the base, with the unique ability to rotate to allow for minor adjustments to alignment without the need to move the entire HBA5
machine.
2.3.1 GLIDE PLATE
The glide plate handle is used to position the alignment head up and down during
the position check procedure.
Tension adjustment screws are located on the glide plate to loosen / tighten
tension of glide plate
2.4 WHEEL BASE
The wheel-base is used to easily move the HBA5 in front of the vehicle while adjusting or checking
headlamp adjustment. It is designed with both a front and rear eccentric axle for easy adjustment while
leveling the unit. The front axle is adjusted once to level the front of the base, and the rear axle with
the attached scale is used to adjust the HBA5 to the slope of the floor in the bay where headlamp
adjustments are done.
2.4.1 FLOOR SLOPE ADJUSTMENT WHEEL ASSEMBLY
The wheel-base contains 3 wheels. The rear wheel is eccentric, and is used in conjunction with the laser
to match the alignment head with the slope of the floor. The adjustable rear wheel operates by way of a
turning lever, and numeric scale that is used by the operator to measure and
record the floor’s slope.
Make sure to loosen the attachment screws for the axle block before
attempting to adjust the wheel. Damage will occur if this step is not
accomplished first.
2.4.2 UNIT LEVELING ADJUSTMENT WHEEL ASSEMBLY
The front wheel is also eccentric. This wheel is used to set the overall level of the unit during initial set-up. A small scribe
mark is placed on the eccentric axle during calibration at the factory; align this scribe mark with the indicator arrow on the base
