> GENERAL Your ESF is rejected. Please provide a revision within 14 days
> 2.5.2 Double 20 AWG for current capacity does not sound like a safe plan
> ,   are there fuses?       check   connector spec , maybe it cannot take
> 18awg...
> 2.7.1 FIgure 18: Please provide beter resolution of schematics . I do not
> see where is the Light input and our our activate when >60V or AIR
> activated.
> 2.8.2. EV4.4.6 NOTE : TMSP resistivity is 15K , is this a problem ?
> EV4.4.6 specs 10k for 300V system
> 2.10 use 300V+ rated resistors . 160V rated resistors in serie will work
> but is definitively not a good Eng. practice. All resistors should handle
> 300V . If 1 resistor fails close , the other one will not be able to handle
> the voltage.   Paralelle resistor is Good if 1 fails open.( most likely)
> 2.11.13 EV4.7.1 Please provide beter rending of the HVD. HVD should not
> require tool to open ;  is there an additionnal key or addition on the HVD
> connector?
> 3.1.10 Is charger compatible with single phase charging?
> 3.1.10 --> charger spec :

> 3.1.10 --> 2 phase / 3 phases : so NO :) it would be important to remin
> the team that there will be no 3phase at the event
> 3.1.10 -->AND the 2 phase is 340V ..  Team need to come with the gas
> generator ( or something!) to supply appropriate Vinput
> 3.1.10 ev8.3.6 Please show picture of your emergency stop button
> 4.2 EV4.9 Please detail the HV connections( cable /routing/connections)
> of the energy box to the Accumulator ( HV)
> 6.1 EV2.1.2 Please provide detailed rendings that clearly show the motor
> casing
> 6.1.3  Provide rending of rear motors
> 6.2 EV2.1.2 Please provide detailed rendings that clearly show the motor
> casing
> 7.1 ev2.3.10-11 Please clarify if you use the SPI output or the PWM
> output. AS the PWM output is filtered (RC of figure 46) it can be concider
> as a ratiometric sensor , for PWM output , please detail operating duty
> cycle  range ( eg 10% to 85%) 0 /100% should trigger  a fault
> 8.1 EV4.1.7 STEVAL-ISA132V1 is a PFC converter ( AC/DC) not DCDC ... How
> do you get it to work properly? please provide visual proof for
> spacing/clearance requirement for rule EV4.1.7
> 8.1.1 EV4.1.7 section 8.1.1 is missing and would provide important
> information for compliance to EV4.1.7 , please provide.
> Figure 6 How do you supply 24V from DCDC at startup? is DCDC connected in
> front or AIR ? Please supply detail connection of DCDC to supply GLV.Figure
> 6 does not provide enough details
> 8.2 no section 8.2  : is there some information missing?
