• The amplifire A4 is used to set the output signal full-scale value (Imax), using the DIP switches SW4 ~
SW10.
Note that the 24VDC voltage output mode is set when all DIP switches (SW4 ~ SW10) are turned on.
Imax
• The amplifire A2 is used to add the stop gain and the stop bias to the output.
When the [ST] input is turned off, the stop gain (multiplication of output at the [ST] input ON by 0
~300%) and the stop bisa (addition of 0 ~ 60 % of full-scale output ) are valiated.
The upper limit times is restricted by the built-in stop timer.

• When the [RC] input is turned off, the [PP] - {PN] output is also turned off.
The [RC] input is generally used whil it is turnedon.
It is also possible to inver the logic so that the output is validated when the [RC] input is turned off.
• When the [SC] input is turned on, the aux.pouer output is validated.
The upper limit time is restricted by the built-in aux.power output timer.
Aux. power output
( Note ) Restriction of Aux.power output
• Set the aux.power output timer (valiable : 0 ~ 30sec) to
the value shown in the right or less. (Any value out of
this range will not be accepted.)
• Make it a rule to secure the [SC] input ON/OFF interval,
to 3 minutes or more, which is used to validate the
aux,power output.
• The output current of power amplifire is determined by
the rated current of clutch / brake used in condition.
Note that the graph shown at right is not the output cur-
rent as aux,power amplifire.
