Turning the Output On or Off Rapidly
In the factory default settings, the internal output relay of this product is activated linking to the
output on/off. In the output off state, the internal circuit and the output terminal of this product are
physically separated. On the other hand, if the output relay chattering causes any problem, or if you
want to turn the output on or off rapidly, you can disable the activation of the output relay. In that
case, the output relay is fixed to the on state and the operation to turn the output on/off is performed
by the semiconductor device. The output off state means the state of high impedance. Table 4-16
shows the list of the output terminal impedance (reference values in the rear output terminal) in the
output off state when the output relay control is disabled.

Note 1: The reference value of output terminal at rear panel.
Note 2: N indicates the number of the power units energized.
-------- Notes ------------------------------------------------------------------------------------------------------------
Even when the activation of the output relay is disabled, the relay is turned off if the protection
function is activated. While the error message appearing when the protection function is
activated displays "Press Enter Key," pressing the ENTER key clears the message and turns on
the output relay again although the output remains off.
The output relay is in the off state during the wait time at power-on or after changing the
power unit energization setting even if the activation of the output relay is disabled.
