Operation Overview
Figure 3-13 Stop Sinking Current (Von Non-Latch)
3.9 Short
On/Off
The Load can simulate a short circuit at input by setting it on with full-scale current. The
short circuit can be on/off from the front panel or via remote control. There are two
operations for
SHORT
key on the front panel. One is toggled on/off, and the other is
controlled by key. They are selected in configuration. The
SHORT
key will be enabled
only when the Load is ON.
Toggled on/off means pressing
SHORT
once to enable short circuit, and again to disable it.
Control by Key means pressing
SHORT
and holding it to enable short circuit, and releasing it
to return to normal operation.
The actual value of electronic short depends on the mode and range that are active when the
short is turned on. Its basic limit is the maximum power range the Load can supply. In CC
mode it is equivalent to the programming of full-scale current. In CR mode it is equivalent
to the programming of the minimum resistance for the present resistance range. In CV mode
it is equivalent to the programming of zero voltage. In CP mode it is equivalent to the
programming of the maximum power for the present power range. Turning on the short
circuit does not affect the programmed setting, and Load input will return to the previous
programmed values when the short circuit is turned off.
Note that turning on the short circuit may cause the Load to sink so much current to trig
protection circuit, and will turn off the Load.

Notice
The 63200 series have a TTL signal from RS-485 pin 6 for your application to control the
external short relay. TTL indicates high/low when the short key is set on/off.
