5.11.

Safe-Start and Auto-Restart Modes

When turning On the power supply AC On/Off, it can start to its last setting of Output
Voltage and Current with the output Enabled (Auto-restart mode) or start with the output
Disabled (Safe-start mode). Press and hold the OUT button to select between Safe-start
and Auto-restart modes. The VOLTAGE display will continuously cycle between “SAF” and
“AU7” every 3 seconds. Releasing the OUT pushbutton while one of the modes is
displayed, selects that mode. The default setting at shipment is Safe-start mode.

5.11.1. Auto-Restart Mode

In this mode, the power supply restores its last operation setting. Upon start-up, the
output is enabled or disabled according to its last setting.

5.11.2. Safe-Start Mode

In this mode, the power supply restores its last operation setting and sets the Output to
an Off state. At start-up, the output is Disabled and the Output Voltage and Current are
zero. To Enable the output and restore the last Output Voltage and Current values,
momentarily press the OUT button.

5.12.

Over Temperature Protection (OTP)

The OTP circuit shuts down the power supply before the internal components can exceed
their safe internal operating temperature. When an OTP shutdown occurs, the display
shows “OTP” (O7P) and the ALARM LED blinks.

Resetting the OTP circuit can be automatic (non-latched) or manual (latched) depending
on the Safe-start or Auto-restart mode.

5.12.1. Safe-Start Mode

In Safe-start mode, the power supply stays Off after the over temperature condition has
been removed. The display continues to show “OTP” (O7P) and the ALARM LED
continues to blink. To reset the OTP circuit, press the OUT button (or send an OUT ON
command via the serial port).

5.12.2. Auto-Restart Mode

In Auto-restart mode, the power supply recovers to its last setting automatically when
the over temperature condition is removed.

5.13.

Last Setting Memory

The power supply is equipped with Last Setting Memory, which stores several power
supply parameters at each AC turn-off sequence.

Stored Parameters:

1. OUT On or Off

7. Start-up mode (Safe-start or Auto-restart)

2. Output Voltage setting (PV setting)

8. Remote/Local: If the last setting was Local
Lockout, (latched mode), the supply will return to
Remote mode (non-latched).

3. Output Current setting (PC setting)

9. Address setting

4. OVP Level

10. Baud rate

5. UVL Level

11. Locked/Unlocked Front Panel (LFP/UFP)

6. FOLD Setting

12. Master/Slave setting

(Items 8, 9, 10 are related to Remote Digital Control operation and are explained in Chapter 7)
