Proper Set of the Screw Height in the Control head

Aug 16 2011
One of our customers had a problem in releasing a load in a standard valve Bambi Bucket. The valve did not operate in a consistent and regular manner.  As part of SEI’s ISO Quality Assurance program and following an internal engineering investigation, our senior production assembler identified that the screw shown on the attached photo was set too low.
 
The customer was informed to reset the screw height and has since solved the problem.  Bambi engineering and firefighting division have created a customized gauge to allow Bambi Bucket production assembly staff to standardize the depth of the screw set.  We are sharing this information with our sales representatives and service centers worldwide so that this problem can be both recognized with our customers and mitigated through troubleshooting in the event this is required.

Working instruction for the retrofit of standard valve

Jun 28 2011
Product: Standard Bambi Bucket
Applicability: BB2024, BB2732, BB3542
Operation: Working Instruction for the retrofit of the standard valves
Overview:
A motion study of the valve movement during a dump cycle demonstrated that the end of the valve seal did not always “flip” back to the normal closed position consistently. This characteristic may impact the ability for the valve to achieve a tight seal after each dump cycle.
 
The modification outlined herein significantly improves the motion to achieve a tight seal on the medium series valve after each cycle.

Protection Diodes Incorporated Into The Head Lead Wires Of Bambi Bucket Control Heads

Apr 1 2011
In response to customer feedback expressing concern with the potential for premature switch contact degradation of the dump release switch, on June 24, 2010 SEI incorporated a suppressor diode (“flyback diode”) and a polarity protection diode into our head lead wires. For some customers this change resulted in operational complications, as the head lead wire polarity must be strictly observed. In the absence of hard evidence that dump switches are being impacted negatively, SEI has reverted to the original head lead wire design (no diodes) for all new buckets.
 
If you are concerned about the inductive load presented by the head solenoid, and you wish to continue using your Bambi bucket with the diode configuration to protect your dump switch, SEI will continue to support this, and all parts will be available upon request.

Standard Valve Replacement Instructions

Sep 2 2010
Product: Bambi Bucket Dump Valve Replacement Kit
Applicability: All models prior to August 31, 2010
Operation: Modified valve replacement instructions 
Overview:
Bambi Bucket fabric dump valves (udders) need to be replaced if damaged during operations.  The installation instructions have been modified to correct the previous installation instructions.
 
Apply a 3/16” thick x 5/8” wide bead of butyl rubber sealant in a circle around the inside the bottom of the bucket shell, orientated above the valve grommets. This creates a seal between the shell and the dump valve fabric.
 
Position the bucket with the ballast pouch laying on the ground (6 o’clock position), place the new valve into the bucket with the valve mouth (when closed) parallel to the ground.  When the two halves of the valve mouth are closed together, the corners are in the 3 o’clock and 9 o’clock positions.

Bambi Bucket: Collapsing Instruction

Jul 12 2010
Product: All Bambi Buckets (Standard, Torrentula, Aqualanche)
Applicability: Models from 5566 and up (The IDS of the smaller model buckets can be collapsed readily by hand)
Operation: Collapsing Instant Deployment System (IDS)
Overview:
The IDS uses a hub and spoke mechanism to expand the mouth of the bucket as soon as the bucket is pulled by the suspension lines.
After use, the spokes need to be pushed back inside the bucket (collapsing the IDS) when the bucket is packed for storage. The purpose of this bulletin is to provide a step by step instruction to safely collapse the IDS.

Bambi Bucket: Aqualanche Valve Replacement Instructions

Jun 22 2010
Product: Aqualanche Bucket
Applicability: All models prior to April 12, 2010
Operation: Modified Aqualanche valve replacement instructions
Overview:
The operating amperage of the Bambi Aqualanche bucket was designed to be under 10A. After a period of operation, the operating amperage on some bucket models increased. The higher current draw resulted in tripping the circuit breaker. One other symptom included an audible sound from the valve.
The root cause for the above observations is that a leak developed through the actuator shaft seal.
A modification has been designed to eliminate the leak. The modified design has been tested extensively and proved to eliminate the leak. This bulletin provides a simple step by step work instruction for replacing the existing valve with the modified valve.

Bambi: Head Lead Wire Connection

Jun 10 2010
Ongoing product improvement has resulted in a change to the actuator head lead wire. To eliminate the potential for premature switch contact degradation, SEI has begun to equip its Bambi control heads with a suppressor diode (a.k.a. “flyback diode”).
 
The new head lead wire design is identifiable by the addition of polarity markers on the white (+) and black (-) wires. Note that these polarities must be observed in order for the bucket to function.

Bambi: Aqualanche Bucket Sealing Improvement

Feb 8 2010
Problem:
The operating amperage of the Bambi Aqualanche bucket is set to be under 10A. After a continuous period of operation, the operating amperage on some bucket models can increase. The higher current draw can result in tripping the circuit breaker. Other symptoms include an audible sound from valve that indicates friction on the incorporated parts within the valve.
