2.9 PRELIMINARY CHECK-OUT
For a preliminary electrical check-out of the MAT Power Module a Host Computer, a Power
Module Controller (see PAR. 1.2) and all the necessary interconnection cables are required.
Connect the MAT Power Module DC Output connector for local sensing: Output 1 to Sense 1,
Output 2 to Sense 2 (see Table 2-4). Connect a resistive load across Output 1 and Output 2 that
is capable of dissipating the maximum current and voltage capabilities of the Power Module.
In this procedure the MAT Power Module Control Bus address is 3, (it is set at the factory to 3).
Connect the Kepco Power Module Controller and the MAT Power Module (following check-out
uses a Power Module Model MAT 36-10 as an example) to the Control Bus. Connect the Host
Computer and the Power Module Controller to the IEEE 488 GPIB. Apply the ac power to the
units in the following sequence: MAT Power Modules first and Power Module Controller last. In
the event that this sequence is reversed (the Power Module Controller is connected first, and
then the MAT Power Module is connected second) the operator must send a IEEE 488 GPIB
Device Clear Interface Function via the Host Computer. For proper time delays between com-
mands refer to PAR. 3.3. For details on the CIIL commands refer to PAR. 3.6.3 and Appendix C
as well as the Power Module Controller Manual. The following does not include the IEEE 488
Bus Commands.

Path Fault
Protection
J7
Enables crowbar protection circuit to trip circuit
breaker and shut off unit if path fault detected.
J7
(Default)
Allows software complete control of path fault pro-
tection. Outputs (voltage and current) are pro-
grammed to zero and relays opened to isolate load
in case of path fault.

Loss Protec-
tion
J5
(Default)
Enables crowbar protection circuit to trip circuit
breaker and shut off unit when power loss
detected.
J5
Disables crowbar protection circuit which trips cir-
cuit breaker and shuts off unit when power loss
detected.
