3.5.7 Output on/off control
The main output signal can be turned on or off by using the output on/off switch (OUTPUT) on the front
panel or external control input. When external control is used, however, the output on/off switch
(OUTPUT) can only be set to OFF.
The LED in the output on/off switch (OUTPUT) turns on when output is turned on.
The LED blinks when output is turned off by the protection function of this product.
For protection cancellation, press the output on/off switch (OUTPUT).
When output is turned off, an attempt to turn on output can be accepted only after 2 seconds elapse for
safety.
To turn on output again, wait for at least 2 seconds after output is turned off.
A relay contact is used to turn on and off output. To protect the relay circuit, a muting circuit is actuated at
the time of output on/off switching, so that the monitor output indicates zero for a very short period and
voltage display on the output LED meter may fluctuate.
When output overcurrent, excessive internal power loss, abnormal internal temperature, or output
overvoltage is detected, the protection function activates and the overload LED turns on.
When the overload LED is on, output cannot be turned on.
When output overvoltage is detected while output is on, output is turned off.
For other overload factors, output turns off when overload lasts 10 seconds or more.
[Precautions in use]
The relays switching the outputs on and off are the life span parts. Again and again switching the outputs
on and off may damage the relays. In particular, under conditions of use that switching the outputs on and
off frequently, failure may occur even within the warranty period of this product. So, please avoid such
usage.
A high voltage can occur at the load when output is turned off if a load including an inductance
component is connected, so be careful not to change the load current abruptly.
3.6 Setting at Power-on
Initial values for start-up time can be set by using the DIP switch on the rear panel.
"
Table 3-2 List of DIP Switch Settings
" indicates the function of each switch. Refer to each section
indicated in the column "Section to be referenced" for setting details.
