6.4 Basic Inspection of DVP04PT-S and Error Code

Table

 Checking the wiring

1. Check whether the module is connected to 24 V power, and check whether the POWER

LED indicator on the module is turned ON after the module is supplied with the power.

2. Do not connect input AC power supply to any of the I/O terminals, otherwise serious

damage may occur. Check all the wiring again before supplying power.

3. Use only the wires that are packed with the temperature sensor for the analog inputs, and

separate the wires from other power cables or any wire that may cause noise.

4. The terminal FG is grounded for noise suppression.

5. Please connect the terminal on the power module and the terminal on the

temperature measurement module DVP04PT-S to the system earth point, and ground the

system earth point or connect it to the machine cover.

 Checking the program

1. Check whether the use of the devices in the program is correct.

2. Check whether the setting of the number of values which will be averaged and the related

setting are correct.
