4. Note the DPM has a differential input so the cold side IN LO Pin 7 is connected to the 2 5V halfrail The Mutual Shutdown System Equipment containing some kinds of op amp is vulnerable to damage when only one of the 17V rails fails as in this case excessive supply currents can be drawn damaging fuse resistors on the modules When both 17V supplies are working normally current flows through DZ8 OPTO1 and across to the RH OPTOI is on so the base drive to TR22 is shunted away and the 723 works normally Likewise TR24 is kept on via R100 and ensures TR28 stays off If either supply fails there is insufficent voltage to keep DZ8 conducting and current flow ceases in the mutual shutdown line TR22 is turned via the special supply generated by D13 C26 and the internal node of the 723 IC3 is pulled down to ground turning it off Likewise in the 17V supply TR28 is turned via the special supply generated by D14 C25 and the internal node of IC4 is pulled down to ground turning it off C27 30 delay the action of mutual shutdown sufficiently to allow the supplies to start as they may not rise to working voltage at exactly the same rate 17 18 When shutdown has ocurred the supply is reset by turning the mains briefly off and on R100 discharges C25 so that the circuit is ready for use at the next switch on The special supplies generated by D13 C26 and D14 C25 are designed to discharge ve

62. to signal processing equipment It should be noted that if a complete rack containing a CPS2000 unit is to be operated from a different mains supply level then the unit should be withdrawn from the rack in order to reselect the mains voltage setting at the same time as resetting any other equipment The other important consideration when rack mounting the unit is the need for natural convection of air over the case and an unrestricted air flow through the unit Note that air is drawn in at the front of the unit and expelled through the rear panel Good ventilation BELOW the unit in the floor or back of the rack and similarly ABOVE the unit at the top of the rack will ensure a path for continuous air flow Other equipment in the rack which is known NOT to produce a significant amount of heat should be mounted BELOW the unit Equipment that also relies on good air flow within the rack ie most power amplifiers and other power supplies should be given due consideration and some space should be provided between such units and between these and the CPS2000 unit Forced convection by means of a fan tray may be desirable in this situation The CPS2000 will operate as a free standing unit without requiring any special cooling arrangement but should not be allowed to be accidentally or deliberately covered over in any way Do not operate the unit with the top cover removed as this exposes hazardous voltages The filters on the cooli
