2.4.2 Connection of Analog Input Cable
Precautions on wiring
Note the following points, and make connection using the cable supplied with the unit.
- The wiring should be shorther than 3 m.
- When removing the wire's insulation, be careful not to scratch the core wire.
- Make sure stress is not applied to the cable.
- Confirm the cable is connected properly before supplying power.
2.4.3 Potentiometer Input
Connect a potentiometer to the analog input connector externally. Values change in response to the turn
of the potentiometer.
Circuit diagram
- Do not connect anything with the 5/6 and 7/8 pins.
- Min. potentiomeneter resistance should be 5 kΩ.
[Example] Writing of the clock setting value
The value of the special data register (DT90040) that corresponds to the analog input CH0 is sent to the
set value area (SV0) of TMX0 to set the time for the clock.
