FIGURE C-5. OPN, CLS — OPEN, CLOSE RELAY COMMANDS
FIGURE C-6. RST — RESET COMMAND
FIGURE C-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 MBT to execute the confidence test procedure defined for the MBT
power supplies (IST is functionally identical to CNF for MBT power supplies. The procedure consists
of opening all power relays, programming voltage and current to their maximum values, switching
polarity, 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.
