4-6. Output shut-off (SO) control via rear panel J1 connector
Contacts 2, 3 and 15 of J1 (Fig.3-2, Item 24) serve as Output Shut-Off (SO) terminals. The SO terminals accept a
2.5V to 15V signal or Open-Short contact to shut off the power supply output. To rise the output again after shut-off,
apply the reverse-logic signal (Table 4-2) to the SO terminals. This function is useful for connecting power supplies in
a “Daisy-chain”. The SO control can be used also to reset the OVP and Fold Protection.
◆
Refer to "4-2. Over voltage protection (OVP)" and "4-3. Under voltage limit (UVL)" for details.
When the unit is shut-off by J1 signal,
the VOLTAGE display will show “SO” to indicate the unit state. J1 contact 15 is
the SO signal input and contacts 2 and 3, IF_COM, are the signal return (connected internally). Contacts 2, 3 and 15
are optically isolated from the power supply output. The SO control logic can be selected by the rear panel SW1
Setup switch.
◆
Refer to Table 4-2 for SW1 setting and SO control logic.
CAUTION
!
In Auto-Restart mode the output will re-rise automatically after reset the SO control,
but in safe start mode pushing OUTPUT button is needed to raise the output again
after reset

4-7. Enable/disable control via rear panel J1 connector
Contacts 1 and 14 of J1 (Fig.3-3, Item 24) serve as Output Enable/Disable terminals by switch or relay. This function is
enabled or disabled by the SW1 Setup switch position 9.
◆
Refer to Table 4-3 for Enable/Disable function andSW1setting.

CAUTION
!
To prevent possible damage to the unit, do not connect any of the Enable/Disable
inputs to the positive or negative output potential.
If the Enable/Disable inputs are opened in Safe Start mode, it is required to short the Enable /Disable inputs
and then press OUTPUT button or send OUT1 command to resume operation. But in auto-restart mode set
these inputs short, and then the output will rise up automatically after output-off by this function.
