FIGURE A-5. OPN, CLS — Open, Close Relay Commands
FIGURE A-6. RST — Reset Command
FIGURE A-7. CNF, IST — Confidence Test, Internal Self Test Commands
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:
OPN
Disconnects the load from the power supply specified by the operand.
CLS
Connects the load to the power supply specified by the operand.
Example:
OPN :CH22
Opens the relay of the power supply at node address 22.
CLS :CH14
Closes the relay of the power supply at node address 14.
OPN, CLS
Syntax:
RST DCS :CHnn
Function
:
This operator is used to return a power supply to its power-on state. The output voltage and current
are programmed to zero and the output relay of MR and MGR models is opened.
Example:
RST DCS :CH13
The power supply at node address 13 is reset.
RST
Syntax:
CNF or IST
Function
:
Causes power supply to execute confidence test.
Description:
The CNF operator commands the MAT to execute the confidence test procedure defined for the MAT
power supplies (IST is functionally identical to CNF for MAT power supplies. The procedure consists of
opening all power relays, programming voltage and current to their maximum values, switching polar-
ity, checking for error flags, then programming voltage and current to zero. The results of CNF are
obtained through the STA command.
Example:
CNF
All power supplies in the daisy chain execute confidence test.
IST
All power supplies in the daisy chain execute self test.
