Control Logic (Sink/Source) Change - Mitsubishi Electric FR-A820-00046 Instruction Manual

Installation and wiring
2.6.2

Control logic (sink/source) change

Change the control logic of input signals as necessary.
To change the control logic, change the jumper connector position on the control circuit board.
Connect the jumper connector to the connector pin of the desired control logic.
● The control logic of input signals is initially set to the sink logic (SINK) for the FM type.
● The control logic of input signals is initially set to the source logic (SOURCE) for the CA type.
(The output signals may be used in either the sink or source logic independently of the jumper con-
nector position.)
Fig. 2-26:
NOTES Make sure that the jumper connector is installed correctly.
Never change the control logic while power is ON.
To change the control logic for the FR-A800-GF, remove the control circuit terminal block and
change the jumper connector position. (Refer to page 7-11 for details on how to remove the ter-
minal block.)
After changing the jumper connector position, reinstall the control circuit terminal block securely
in place.
