The OELPS is administered to determine English Proficiency in the domains of reading, writing, speaking, and listening. If a primary or home language other than English (PHLOTE) is stated on the survey, the staff member is to immediately contact the EL Coordinator wh o will arrange for the OELPS Screener to be administered within the first 30 days of the start of the school year or within two weeks of enrollment if after the beginning of the year. A designated staff member who has been trained in the procedures of administering the Language Usage Surveys is responsible to review the Language Usage Survey responses to determine the student’s primary language, home language, immigrant student status, and if the student needs a language screener to determine EL status.

The survey is included in the registration packet or the online registration system. For example, the district: Must enroll all students regardless of the students’ or their parents’ or guardians’ actual or perceived citizenship or immigration status must protect students from discriminatory harassment on the basis of race, color, national origin (including EL status), sex, disability, or religion Must not prohibit national origin-minority group students from speaking in their primary language during the school day without an educational justification and Must not retaliate, intimidate, threaten, coerce, or in any way discriminate against any individual for bringing civil rights concerns to a school’s attention or for testifying or participating in any manner in a school, OCR, or DOJ investigation or proceeding.Įvery student who enters the school district completes a Language Usage Survey. In addition to the common civil rights with respect to EL student programs, Federal law also prohibits all forms of race, color, national origin, sex, disability, and religious discrimination against EL students. I would venture to say that unless you were starting and stopping multiple times a minute, a 50 watt resistor with proper heat sinking would suffice.Under Title VI of the Civil Rights Act of 1964 (Title VI) and the Equal Educational Opportunities Act of 1974 (EEOA), public schools must ensure that EL students can participate meaningfully and equally in educational programs.

This should be a very conservative estimate. A 50 watt resistor can safely dissipate 3,000 joules/min so a start /stop every 40 seconds would be permitted. I did a rough calculation assuming 2,000 rpm and a mass of 20 kg located on a rim 4 cm in radius and calculated about 2,000 joules of energy. You could do a calculation of the required wattage by assuming the the entire kinetic energy of the motor, spindle assembly, and work was being absorbed by the resistor and making a guess as to mass and its distribution and the maximum rpm. Transient current will be limited to a few tens of amps which will be easier on your relay contacts and reduce EMF.Īs to the wattage of the resistor, the duty cycle of the brake will be minimal so a 1000 watts is overkill. I have a 3,000 mfd filter in my power supply, directly connected to the bridge rectifier and I was destroying switch contacts until I added a inrush current limiter to the circuit.īut the question that I have is why bother with the capacitor and bridge at all? The capacitor will quickly discharge to zero volts after initial contact is made and really serve no useful purpose. On a conversion of my lather to a dc PWM driven motor, I was destroying MOSFET transistors rated at 500 amps pulsed until I realized that I had to add a transient snubber to the motor. You will also create a large amount of EMF which could interfere with the ELS. As such the circuit can experience transient currents into the thousands of ohms which can destroy the bridge rectifier. The capacitor will essentially be a dead short when the brake circuit is energized. It appears that you have a bridge rectifier to handle the fwd/rev situation so the capacitor always see the correct polarity. It looks like you have a great start on the ELS.
