LEAD-ACID BATTERIES-EXPLOSION HAZARD
.JPG){kind=small}
Do not allow open flames or sparks of any kind near a battery. Highly explosive gas is generated when charging a battery that can remain in battery cells for extended periods of time after charging is complete.
- Always wear appropriate PPE including rubber apron, gloves, boots and full face shield when performing service or maintenance to any lead-acid batteries.
- Do not place metal or other conductive objects on top of battery. Arcing may occur causing damage to the battery and/or serious personal injury or death.
- Use only chargers matching the voltage and amperage of the battery being charged. Overcharging a battery can cause damage to the battery, charger and/or serious personal injury or death.
- Turn off charger before disconnecting battery from charger. Arcing between battery and charger connectors can cause damage to the connectors and/or serious personal injury or death.
BATTERY WASH WATER HAZARDS
HEAVY METALS:
Battery wash water contains heavy metals including (but not limited to) lead and antimony, which through prolonged exposure can lead to serious, long-term, adverse health conditions.
EXTREME pH LEVELS:
Highly acidic (low pH) as well as highly alkaline/ basic (high pH) solutions can cause severe burns, release toxic fumes, and cause violent chemical reactions when mixed with water or when mixed together.
- pH values outside of the BHS allowable range of 5 to 9 should be treated as “extreme” and caution should be taken to avoid direct contact with such solutions.
- Always wear appropriate PPE including rubber apron, gloves, boots and full face shield when working in contact with any battery wash water.
TREATMENT CHEMICALS:
Use of chemicals not approved by BHS to treat wash water may result in the release of toxic fumes.
COMPRESSED AIR HAZARDS
AVOID HIGH PRESSURE AIR - High pressure, compressed air can dislodge particles that can enter the eyes or abrade skin. Hearing can be damaged by the sound of escaping high pressure, compressed air. Relieve pressure before disconnecting air lines. (See Item #4, Figure 3 in the DE-ENERGIZATION procedure). Tighten all connections before applying pressure. Keep hands and body away from holes which eject air under high pressure.
High pressure, compressed air can enter the blood stream through a break in the skin or through a body opening. An air bubble in the blood stream is know as an “embolism”, a dangerous medical condition in which a blood vessel is blocked by the air bubble. An embolism of an artery can cause coma, paralysis or death depending upon its size, duration and location. A small quantity of air (or other gas) in the blood can quickly become fatal.
OPERATIONAL SAFETY
OPERATIONAL SAFETY
- Only personnel trained in the proper and safe operation of BWC units may operate or service the BWC.

FUNCTIONAL DESCRIPTION
CONSTRUCTION:
- All models constructed of 304/316 stainless steel sheet and structural shapes.
- All hardware stainless steel or bright galvanized finish.
- All seams welded or sealed for water tight design.
- All welding conforms to all applicable AWS specifications.
- All plumbing components are CPVC Sch 80, brass, nylon, or similar corrosive resistant materials.
WASH CYCLE:
Battery wash down is accomplished via eight, round-pattern spray nozzles mounted on two adjustable height manifolds to accommodate a wide variety of batteries. The wash down is a low pressure - high volume flood wash that removes most dirt, debris and acid residue left on top of the battery from charging. A battery wash cabinet equipped with a neutralizing cycle includes a timed injection of conditioner preset to inject 1.5 oz of conditioner in 25 seconds. Monitoring the pH of the effluent is required to obtain the optimum timer setting. The recommended pH range is from 5 to 9 with 6 to 8 being ideal.
BLOW-OFF CYCLE:
BWC-2
At the end of the wash cycle, the automatic doors open and the battery is ready for the unload/blow-off function. As the operator depresses and holds the “unload” button, the power rollers transfer the battery out of the cabinet and past the air manifold. Eleven “knife blade” type air nozzles direct high volume air at an angle to the battery to remove excess standing water prior to the battery exiting the cabinet.
BWC-3
The above blow-off procedure is the same on this model except with the in-feed conveyor option, the blow-off is automatic at the end of the wash cycle and the battery automatically unloads itself without control input from the operator.

INITIAL START-UP PROCEDURE
PHOTO EYE
Verify alignment and operating mode of the photo eyes as follows:
A.) Photo eye mode must be set to “LIGHT ON”. The settings are found under the cover on top of the photo eye.
B.) Without a battery in the cabinet (or on the infeed conveyor for BWC-3 units) and the power turned “ON”, all three lights should be lit (green, yellow, and red). This signifies the photo eyes are properly aligned with the reflectors located on the opposite side of the cabinet. If all three lights are lit, continue to step C. If all three lights are not displayed, refer to Section 4-2 for the photo eye adjustment procedure and adjust the photo eye until all three lights are lit.
C.) Verify that any object breaking the beam changes the displayed indicator lights from three lights (green, yellow and red) to one green light by sliding a piece of paper immediately in front of the photo eye (between the photo eye and the cabinet).
NOTE: Failure to properly align the photo eye may cause control logic and performance problems.
OPERATION
CONTROLS
The BWC-2 is operated using a 3-button control pendant. The BWC-3 is operated using a 2-button control box located on the left side of the cabinet. The function of these buttons are:
UNLOAD/BLOW-OFF (BWC-2 only) - Activates the conveyor to unload the battery and activates the air blow-off to remove excess water from the battery.
START - Initiates the wash cycle. Starts the conveyor to load the battery into the cabinet.
EMERGENCY STOP - Immediately stops all functions in the event of a problem.
The emergency stop will NOT stop the door from lowering once door is in motion for units manufactured prior to October 1ST, 2009.

OPERATING PROCEDUR
The following procedures will guide the operator through the battery wash process.
OPERATIONAL PRE-CHECK:
The following items should be verified prior to every wash cycle:
- AC disconnect is in the “ON” position and “Power Available” indicator light is on.
- Emergency stop is in the reset (pulled out) position.
- Air pressure is available; 90 - 110 psi
- Water supply is available:
- If using an RNS system, verify the RNS unit is in the proper mode for use with a BWC unit. Refer to the manual supplied with the RNS unit for the proper operational procedures for that unit.
- If the water supply is connected to plant water, verify the plant water supply valve is open, providing water to the BWC.
- Neutralizer container has at least 1” of solution (if equipped with NC option).
- BWC door is fully open and cabinet has fully drained from previous wash cycle.
NOTE: A small amount of water (1” or less) will remain in the sump area after drainage is complete.
- Sump screen is clear of debris and is properly positioned so that no gaps exist that would allow any debris into the sump area.
OPERATION:
- Prepare battery for loading into BWC A.) BWC-2 : i.) Position the extractor so the battery is centered left- to-right with the BWC. ii.) Align roller height of battery extractor to the height of the BWC rollers. B.) BWC-3: i.) Position the battery over the center of the infeed conveyor. ii.) Lower the battery onto the center of the infeed conveyor.
- Load the battery A.) BWC-2 : i.) Depress and release the “Start” button on the control pendant. ii.) Once the conveyor starts, slowly move the battery from the extractor into the BWC until the BWC conveyor loads the battery completely into the BWC. B.) BWC-3: Depress and release the “Start” button on the control pendant.
- Once the battery passes the photo eye inside the cabinet, the door will lower and the wash cycle will begin. If the unit is equipped with the “NC” option, neutralizer will be added automatically. The wash cycle will last for approximately 45 seconds. The door will automatically open after wash cycle is complete.
- Unload the battery A.) BWC-2 : i.) Ensure the battery extractor is in front of the BWC and the battery compartment is aligned with the BWC as done in step 1-A. ii.) Depress and hold the “Unload/blow-off” button to move the battery out of the BWC onto the extractor. iii.) Once the battery stops moving out of the BWC, release the “Unload/blow-off” button. iv.) Use the battery extractor to move the battery completely onto the battery compartment of the extractor. B.) BWC-3: No operator action is required. The battery will automatically unload onto the infeed conveyor upon completion of the wash cycle. NOTE: The longer a battery is allowed to remain inside the BWC-2 or on the BWC-3 infeed conveyor after the wash cycle is complete, the more water will be allowed to drain from between the battery cells and out of the bottom of the case. This will reduce the amount of water that will drip on the fl oor and the extractor. BHS recommends allowing the battery to sit approximately 2 minutes for sufficient drainage.
Ensure the battery cables are positioned on top of the battery so they do not catch on the door or sides of the cabinet when loading and unloading the battery.
KEYED, MANUAL OVERRIDE OPERATION
The following explains the operating procedures for the keyed, manual override switches.
MANUAL DOOR OPERATION
- Ensure door travel path is clear of any obstructions.
- Insert key into manual door selector switch. See Figure 3-3.
- Turn and hold the key to either the “RAISE” or “LOWER” position until the door has completely raised or lowered.
- Release the key and remove it from the switch
MANUAL CONVEYOR OPERATION
- Care should be taken while performing manual conveyor operations.
- Keep all hands and objects clear of powered conveyor at all times.
- When transferring a battery out of the BWC-2 using the manual override, a battery extractor MUST be present to accept the battery exiting the cabinet.
- Insert key into manual door selector switch. See Figure 3-3.
- Turn and hold the key to either the “IN” or “OUT” position until the desired conveyor travel is obtained.
- Release the key and remove it from the switch

MAINTENANCE
PERIODIC MAINTENANCE & INSPECTION
It is imperative that all equipment be inspected and maintained on a regular basis to ensure proper operation of the BWC.
BHS recommends the BWC be inspected and serviced once per week. Use the included form IF-5015 (BWC-2 / BWC-3 WEEKLY MAINTENANCE CHECKLIST) as a guide. A complete Preventative Maintenance (P.M.) inspection and servicing should be performed every 3 months. Use the included form IF-1122 (BWC SERIES PLANNED MAINTENANCE INSPECTION REPORT) as a guide.
NOTE: The inspection/maintenance intervals recommended by BHS should be evaluated and adjusted (if needed) based on the actual usage of the wash system as well as the condition of the batteries being serviced.
PHOTO EYE ADJUSTMENT
INDICATOR LIGHT STATUS
- Green only:
-Photo eye is aligned and target beam is blocked. -Photo eye is misaligned. -Sensitivity is set to absolute lowest setting (aligned or mis-algined)
- Yellow and Red: Photo eye is aligned but unstable (sensitivity is set too low.)
- Green, Yellow and Red: Photo eye is aligned and stable.
ADJUSTMENT PROCEDURE
- Verify there is power to the unit and the main disconnect is in the “on” position.
- Ensure there is no object (battery or debris) between the photo eye and the reflector.
- Open the top cover by loosening the cover screw and ensure the mode setting is set to “light-on” (L-ON).
- Increase the sensitivity to the maximum by turning the sensitivity adjuster fully clockwise.
- If all three lights are not illuminated, carefully loosen the photo eye mounting hardware until slight movement of the photo eye can be achieved.
- Rotate the photo eye slightly in either direction until all three lights are lit and retighten the mounting hardware.
- Slowly decrease the sensitivity by turning the sensitivity adjuster counterclockwise just until the green light goes out. This is the instability point.
- Increase the sensitivity (clockwise) and set at midpoint between the instability point and the maximum setting. All three lights should be lit.
- Verify proper operation of the photo eye by sliding a piece of paper immediately in front of the photo eye (between the eye and the cabinet). #Once the beam of the photo eye is blocked, the yellow and red light should go out leaving only the green light lit.
- Once proper operation has been verified, close the cover and tighten the cover screw.
