External Input/Output; External Signal Input/Output Function - Mitsubishi Electric AE-200A Installation Manual

9. External input/output

9-1. External signal input/output function

To reduce the risk of injury, do not touch the burrs of the knockout holes.
To use external input/output, a separately-sold external input/output adapter (PAC-YG10HA-E) is required.
When connecting an external input/output adapter (PAC-YG10HA-E), cut out the CN5 knockout hole. (Refer to
section 2-1 "Part names" for the location of CN5.)
Note
When using AE-50, connect the external input/output adapter to each AE-200/AE-50. (External input signal to AE-200 cannot
perform the collective operations (e.g., emergency stop) for AE-50 systems.)
Use caution not to damage the circuit board with tools when cutting out the knockout hole.
Set the [External Input Setting] setting for each AE-200/AE-50 on the [Network] screen.
9-1-1. External signal input function
Using external contact signals (12 or 24 VDC), demand level signals can be input, and the following collective
operations for all connected air conditioning units can be controlled: Emergency stop, ON/OFF operation, and
Prohibit/Permit local remote controller operation.

Note
The relays, DC power supply, and extension cables are not supplied.
The total length of the lead wire and extension cable should not exceed 100 m (328 ft). (Use an extension cable of 0.3 mm
or thicker.)
Cut the excess cable near the connector, and insulate the end of the unused cable with tape.

*1 Select an external power supply suitable for the
relays used. (12 or 24 VDC)
Connect the external power supply in the correct
polarity to input and output the signals.
Connect ⑤–⑧ (see the figure at left) to the negative
side.
*2 Take sufficient precautions against noise when the
cable length is long.
Important
Be sure to use an external power supply (12
or 24 VDC) to avoid malfunctions.
Connect the external power supply in the
correct polarity to avoid malfunctions.
