4.1.7 Controlling the Output Shutdown Using Exter-
nal Contact
This method is used to control the output shutdown using external
contacts.
You can select the following two types of modes through CONFIG
settings. For details on CONFIG settings, see "3.2.4 Unit Configura-
tion (CONFIG)".
When POWER switch trip setting is enabled
The POWER switch trips when pin 10
of the J1
connector is set
LOW level
*1
.
To recover, set pin 10 HIGH level
*2
, and turn on the POWER
switch.
When POWER switch trip setting is disabled
The OUTPUT turns off when pin 10 of the
J1
connector is set
LOW level. (The POWER switch is not tripped.)
To recover, set pin 10 HIGH level, turn off on the POWER switch,
and turn it back on.
*1
LOW level:
Means shorting pins 2 and 10 of the J1 connector, or applying
0 V to pins 2 (common) and 3.
*2
HIGH level:
Means opening pins 2 and 10 of the J1 connector, or applying
3.5 V to 5 V to pins 2 (common) and 3.
■ Shutdown control connection
Pins 2 and 10 of the J1 connector are used.
Use
parts with a contact rating of 5 VDC and 10 mA or more for the
external contact.
To minimize the influence of noise on the output, use a 2-core
shielded wire or a twisted-pair wire to connect the control terminals
and the external contact. Make the wires as short as possible. Suscep-
tibility to the effects of noise increases as the wires get longer. When
wires are long, proper operation may be hindered even if a cable with
anti-noise measures is used.
When using a shielded cable, connect the shield to the - (neg.) output
terminal.
