Power On Service Request (PON SRQ)

Power On Service Request (PON SRQ)

The Power ON Service Request (SRQ) switch is located on the GPIB subplate rear panel S1 switch. Enabling the SRQ switch causes the power supply to send a service request to the computer controller when the power supply is turned on or when it re-initializes after a momentary power interrupt. When the PON SRQ state is tripped, the front panel SRQ LED will also turn on. You can clear the service request and turn off the SRQ LED by performing a serial poll. See “Command Reference” on page 39 for information about the SRQ command. Table 2.3 shows the condition of the SRQ switch in relation to the position reference markings on the rear panel subplate. The location of the switch and reference markings can be found in Figure 2.2, “GPIB Interface Subplate” on page 17.

With the rear panel PON REM switch set to 0, the power supply will start up in remote mode. The green REM LED on the front panel will turn on, signaling that the power supply is under the control of the digital interface card. The output of the power supply is active on startup. See Table 2.5 for more information. To promote load safety, power ON defaults are zero for the output voltage and current limit, and 110% of maximum output voltage for the OVP trip point. See Section 3, “Operation” for more information about the interface commands listed in the table.
