Using the Shutdown Function

Using the Shutdown Function

Use the Shutdown function to disable or enable the supply’s output so that you can make adjustments to either the load or the power supply without shutting off the power supply. Activate this function from the front panel at any time by using the STANDBY switch. You can also activate it via remote control through the rear panel J2 Programming and Monitoring connector, using a 2.5 V to 15 V signal or a transistor-transistor logic (TTL) compatible signal. The input lines for the Shutdown circuit are optically isolated.

STANDBY The STANDBY switch is a press ON/press OFF switch located on the power Switch supply’s front panel. See the front panel diagram in “Front Panel Controls” on page

17.Push the switch to its IN position to activate the Shutdown circuit. The output voltage and current fall to zero and the red S/D (Shutdown) LED turns on. Push the switch once more to reset it to its OUT position and resume normal power supply operation.

Controlling

the Shutdown

Function via

the J2

Connector

The shutdown circuit accepts a 2.5 V to 15 V signal to disable or enable the power supply output. Make connections for signals at connector J2, located on the unit’s rear panel. Set rear panel switch SW1-7 to select signal logic. See “Front Panel Controls” on page 17 for more information about making J2 connector and SW1 switch changes.

To activate the shutdown function:

1.Turn OFF the power supply.

2.Connect the signal source to J2 connector terminal 15 (Shutdown Input/positive) and terminal 14 (Shutdown Return).

3.Set switch SW1-7 to select the desired circuit logic as set out in Table 3.2.

4.Turn on the power supply. The power supply will operate as described in the Supply Output column in Table 3.2, according to the logic you select and the level of the input signal. The S/D (Shutdown) LED on the front panel turns on when the Shutdown circuit is activated.
