SECTION 2 - INSTALLATION UNPACKING AND INSPECTION This instrument has been thoroughly inspected and tested prior to packing and is ready for operation. After careful unpacking, inspect for shipping damage before attempting to operate. Perform the preliminary operational check as outlined in PAR 2.8 If any indication of damage is found, file an immediate claim with the responsible transport service. - Page 20 TABLE 2-2. FRONT CONTROL MAT POWER MODULE ITEM NO. CONTROL FUNCTION (See Fig. 2-1) AC POWER Switch/circuit Breaker Serves as an AC power switch and turns the AC power line off on overvoltage, overcurrent, overtemperature or power loss. CAUTION: DO NOT repeatedly toggle the circuit breaker/switch as this may cause unit to fault.

Page 24: Dc (Output) Grounding
WARNING Keep the Power Module grounded when connected to an AC power source. 2.6.2 DC (OUTPUT) GROUNDING DC output connections are those between the Power Module and the load, including remote sensing connections if necessary. Despite precautions to eliminate noise such as shielding and twisted wire-pairs, output connections may pick up radiated noise of a wide frequency. -

Power for the microcomputer board of the TMA 4882-27 Power Module Controller is provided by a wide range input Power Supply, Kepco Model MRW 150KV. The AC input voltage can range from 95 Volts AC to 264 Volts AC, thereby eliminating the need for an input voltage selector. -

command causes noncatastrophic error messages to be stacked in memory until interrogated by a Status command. AUTOMATIC (TRACKING) CONTROL OF THE CROWBAR LEVEL MAT Power Modules have Overvoltage and Overcurrent Tracking Amplifiers. These amplifiers will cause a crowbar flag, send a catastrophic error to the Power Module Controller and shut the module down if the output goes out of tolerance. -
Page 35: Remote Programming
REMOTE PROGRAMMING 3.6.1 GENERAL Kepco MAT Power Supplies are programmed over a control bus using either SCPI (Standard Commands for Programmable Instruments) or CIIL (Control Interface Intermediate Language) commands. SCPI and CIIL provide a common language conforming to IEEE488.2 for instru- ments used in an automatic test system. -
Page 36: Scpi Programming
For the complete command set, and detailed SCPI programming information, consult the Technical Manual for the applicable controller (the SCPI command sets among Kepco con- trollers are slightly different). See PAR.3.2 to establish the MAT power supply Control Bus (BIT- BUS) address. - Page 37 /**************************************************************************/ Sample Program For KEPCO power supply, using National Instruments GPIB interface card and IBM PC or compatible computer /**************************************************************************/ #include <stdio.h> #include "decl.h" char rd_str[80]; // Input buffer char dat_str[80]; // Output buffer bd,adr; main() { adr = ibfind("DEV6");...

OPN, CLS Syntax: OPN :CHnn CLS :CHnn Function: These commands are used to connect or disconnect the power supply from the load (effective for MR and MGR options only). Description: Disconnects the load from the power supply specified by the operand. Connects the load to the power supply specified by the operand. - Page 51 Syntax: Function: Causes power supply to return operating status to controller. Description: This operator commands the power supply to report its present operating status. Status is reported in the form of a message (character string) as defined below. Any catastrophic error conditions (indicated by * in the table below) which exist will be reported, until the error condition is corrected.
