If thereis damage, notify the shipping carrier and the nearest Agilent Sales and Support Office immediately. Warranty informationis printed i...

Installation 19 Remote Inhibit (RI) Function Switches This function allows the power module outputs to be shut down from a signal (low-true TTL level) applied to the mainframeINH input. The INH input is internally connected to the mainframe remote inhibit (RI) line. This line is normally high andis ...

20 Installation Installing The Module In The Mainframe Figure 2-3. Power Module Installation Note A fully loaded mainframe can weigh over 36 kg (80 lbs). Install the mainframe into the rack (see the"Mainframe Users Guide") before installing the modules into the mainframe. 1. Turn off the mai...

22 Installation Remote Voltage Sensing Figure 2-4B shows the wiring for remote sensing. There is a switch on the output connector that selects either local orremote sensing of the output voltage. To configure the output for remote sensing, do the following: ■ Connect sense leads to the load ■ Make c...

Installation 23 Output Rating The rated output voltage and current specified in Table 1-1 applies at the output terminals of the power module. Withremote sensing, the power module must increase its output to compensate for voltage dropped in the load leads. If youattempt to provide full rated output...

24 Installation 5. In order to maintain proper regulation, the load must always draw at least as much current as is programmed for themodule that is in CC mode. You can maintain regulation over a range of current only as long as this condition remainstrue. 6. As near as is permitted by condition 5, ...

26 Installation The power module is designed to be stable for load capacitances up to the following values: Agilent 66101A 50,000 µ F Agilent 66104A 4,500 µ F Agilent 66102A 20,000 µ F Agilent 66105A 2,750 µ F Agilent 66103A 10,000 µ F Agilent 66106A 1,650 µ F Inductive Loads You may safely connect ...

28 Turn-On Checkout Power Module Turn-On State When you turn on the mainframe, the power module goes through a self-test. All front panel readout digits andannunciators turn on briefly. The panel then remains in the state shown in Table 3-1A. Note The figure assumes the power module still retains it...

Turn-On Checkout 29 In Case Of Trouble Mainframe Failure You can assume there is a problem with the mainframe if there is more than one module in the mainframe and none of themodule fans are on. The trouble also is probably in the mainframe if the module fans are on and the their displays areenabled...

30 Turn-On Checkout Selftest Error Messages Table 3-3 lists the displayed selftest error messages. All these errors are hardware failures that require service. Note If you are using the optional Agilent 66001A MPS Keyboard, it will also display selftest error messages. Table 3-3. Selftest Error Mess...
