See “Customer support” on page 70. If a DSP err or occurs, contact Bose Customer Ser- vice. An amplifie r failure will cause the message, “Power-on self-test incompl ete” to app ear in the upper or lo wer amplif ier section of the PO ST test resu lts. If a 12 C, or code failure occurs, con tact Bose Customer Service. See “Cu stomer support” on page 70. A USB fai l ur e will cause the mess age, “Power -on sel f-test inc omplete” to app ear in this section of the POST results. If a USB fail ure occurs, con- tact Bo se Customer Servic e. See “Customer supp ort” on page 70. Program mer ’ s Note: The USB port is not currently used for communication with t he E4. If a USB failure occurs, the E4 will still function normally for audio pro- cessing and amplification.If a faul t condition occu rs, it is reporte d in the Amplif ier Alarm section of the Error L og. Rail V oltage: The amplifier posit ive and negativ e rail voltages. Normall y, the amp lifier rail vo ltage should be between 1 00V and 190V. V ol tages outsid e this range w ill cause the amp lifier to shut down. In the 70V mode, a normal rail volt age is approx- imately 125 V. In the 100V mode, a normal rail voltage i s approximately 16 5V. Te m p e r a t u r e: The int ernal opera t ing temperat ure of t he amplifi er. Normally, this will be between 0 and 160 de grees Fahr enheit. Output V oltage: The actual output v oltage of the amplifier at the time of the alarm. Output Curr ent: The act ual output current of the ampl ifier at t he time of the alarm. Input S tatus: Th e status of th e input signal to t he amplifi er. Poss ible stat us messag es ar e D C sens e fault, a mplifier m odule fault, AC po wer fault, sleep mode, high-frequency sense fault, and retry fault. Output Sta tus: Th e status of the ampl ifier output at th e time of the alarm. Pos sible status messa ges are “amplifier module muted,” and “speaker relay off.” Fan Speed: The fan speed at the time of the alarm.http://cityini.com/files/fckeditor/bosch-service-manuals-online.xml Operating Mode: The current setting of the out p ut voltage select switch, 70V or 100 V. Compare the output volt age and current for each of the two amp lifier outputs to dete rmine the n ature of th e problem. In the 70V mode a normal rail volt age is approximately 125V. In the 100 V mode a normal rail volt age is approximately 165V. If one of the rail s shows a voltage, an d the other does not, the amplif ier should be re placed. As you review all alarm records you can compare the plu s rail voltage in eac h of the status se ctions. For example, a drop of 50 in one statu s could ind icate a brownout condit ion occurred.The unit should b e replaced. AC Power Fault: Might b e an AC line dr opout or s ever e brownout, or simply AC power turned off with out first placing the E4 in standby mode. Y ou can check that the power has been removed from the E4, or that you experie nced a power dropout. Sleep Mode: The host microcontr oller has told the amplifier and power sup p ly t o turn off. Th is only occurs in c onjunction with another al arm (usually AC pow er fault), because it in itself i s not an alarm condit ion. When an AC po wer dropout occurs, the amplifie r immediately shu ts the amplifie r and speaker relay off, then the other proc e ssi ng is shu t down. This all ha ppens fast enough to prevent da ta loss or corrupti on, and to prevent lou d pops in the s peakers. When this occurs you should check the alarm history to determine what othe r faults occurred at th is time. High-Frequency S ense Fault: This protection mode is designed to prevent damage to t he amplif ier or speakers from excessive high-frequency aud i o or ultrason ic energy. Generall y, this fault results in a one- time 3-second dr opout. If, when the amplifi er tries to restart after 3 se conds, the excess HF is still present, the amp (and speaker relay) will remain off for another 3 second s and the loop repeats.http://www.drupalitalia.org/node/77018 Six of these in a r o w will cause the amp t o shut down, and w ill trigger a Ret ry Fault. When this fault occurs you can check your program material for excessive high-frequency content, or for a potential ground loop which has created an oscillation int ernal to t he E4 unit. Y o u can also r educe th e output ga in for this amp lifier zone i n an attempt to reduce the high-frequen cy energy going to the amplifi er. Retry Faul t: The ampl ifier h as trie d to star t up or recover from a fault condi tion at le ast six ti mes. When this oc curs, you wil l need to place the E4 un it in st andby and then p r es s the ST ANDBY b ut- ton again to clea r the fault, at which time the E4 unit will again try to sta rt up. When this occurs you shou ld check the alarm hist ory section of the Am plifier Alarm to determin e the exa ct faul t type th at trig - ger ed the Retry Faul t. Input and output al arm history This part of the Error L og d isplays the sequence of fault condi- tions wher e “0” is the i nitial faul t report ed followed by “1-6”. W ait a few seconds an d tur n the POWER swit ch to ON. Wait a few seconds and turn the POWE R switch to ON. Th en press ST ANDBY on the front panel. Re connect one c able at a ti me and check t he Error Log. If this is the case y ou should select the appropriate COM port and click the Tr y A g a i n button. Program mer ’ s Note: Before dismissing the “Cho ose COM port” dialog, select the COM 2 po rt and click Tr y Again. No Yes The amplifi e r is in “protect” mode.
