Precautions before use

Power

●Be sure to use the unit under the specied voltage (AC power specications: 85 - 264VAC / DC power specications: 10.8 - 25.2VDC).

●Inverter power source cannot be used.

Input signal wire

●Connection wiring from sensors shall not be kept in the same or parallel conduit or cable as the power source, power or high voltage cables. If you fail to separate the wiring, noise may be superimposed on the signal wire, resulting in malfunctions.

●

Use shielded wire for input power connections with the shortest possible metal conduit.

Terminal

●

Check that the screws have not come loose due to vibrations after a certain period of time.

Operating environment

●Do not install the unit in the following places or conditions.

●●Places exposed to direct sunlight, or places where the ambient temperature exceeds a range of 0 - 45ºC.

●●Places where the relative humidity percentage exceeds a range of 35 - 85%, or places subject to condensation due to rapid change in humidity.

●●Places subject to corrosive and/or combustible gases.

●●Places subject to a large amount of dust, salinity, and/or ferric substance.

●●Places susceptible to noise (including static electricity).

Wiring to Power Source and Sensors (DT-501XA/DT-501XD)

Note) In order to prevent electric shock, be sure to turn the power OFF. Be sure to use the unit under the rated voltage (AC power specifications: 85 - 264VAC / DC power specifications: 10.8 - 25.2VDC). The inverter output (output to connect a motor) cannot be used as power. Connection wiring from sensors shall not be kept in the same or parallel conduit or cable as the power source, power or high voltage cables. If you fail to separate the wiring, noise may be superimposed on the signal wire, resulting in malfunctions. Use shielded wire for input power connections with the shortest possible metal conduit.

• Mode 4

The teaching function can be used to automatically change the value of parameter items (P3, P4), and calculate the present measurement value from the teaching setting value as below.

When the input frequency is outside the input frequency range, “EE-2” is displayed, and the teaching function cannot be used.

Input frequency range●: 1Hz

The P3 scaling value maintains values after decimal point up to 7 digits inside. Note that because the number of digits after decimal point that can be maintained in the parameter setting is up to 5, values in 5 digits or more after decimal point will be rounded o when you enter the value in the parameter setting. * If the P3 calculation value exceeds 999999, the P3 value will be forced to be “999999”.
