Temperature Sensor Units
Section 7-5
Using Temperature Sensor Units
Connecting Temperature
Sensor Units A maximum of three CPM1A-TS002 and CPM1A-TS102 Temperature Sensor
Units can be connected, because each is allocated four words.
Setting Temperature Ranges
Note (1) Always turn OFF the power supply before setting the temperature range.
(2) Never touch the DIP switch or rotary switch during Temperature Sensor
Unit operation. Static electricity may cause operating errors.
The Temperature Sensor Unit’s DIP switch and rotary switch are used to set
the temperature unit, to select 2-decimal-place Mode is to be used, and to set
the temperature input range.
