6.3 Basic Inspection of DVP06XA-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. Please isolate the analog input signal cables from other power cables.

4. If the analog inputs are connected to current signals, the terminals V+ and I+ have to be

short-circuited.

5. If the ripple in the input voltage results in the noise interference with the wiring, please

connect the module to the capacitor having a capacitance within the range between 0.1 µF

and 0.47 µF with a working voltage of 25 V.

6. Please isolate the analog output signal cables from other power cables.

7. If the ripple is large for the input terminal of the load and results in the noise interference

with the wiring, please connect the module to the capacitor having a capacitance within the

range between 0.1 µF and 0.47 µF with a working voltage of 25 V.

8. Please connect the terminal on the power module and the terminal on the analog

output module DVP06XA-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.

 CR#30: Please refer to the table below for more information about the error code stored in

CR#30.

Error description Content b15~b8

Power source abnormal (low voltage

alarm)

K1 (H’1) 0

User setting D/A output exceeds range K2 (H’2) 0

Setting mode error K4 (H’4) 0

Offset/gain error K8 (H’8) 0

Hardware malfunction K16 (H’10)

Digital range error K32 (H’20)

Average times setting error K64 (H’40)

Instruction error K128 (H’80)

Reserved

Note: Each error code will have corresponding bit (b0 ~ b7). Two or more errors may happen

at the same time. 0 means normal and 1 means having error.

Example: If the digital input exceeds 4,000, error (K2) will occur. If the analog output exceeds

10V, both analog input value error K2 and K32 will occur. (A/D does not support

displaying error K2.)
