I/O signal wiring

• Check that I/O signals are connected correctly.
If the DO forced output mode is used, the pins of the CN3 connector can be forcibly switched on/off. This mode is used to
check the wiring. In this case, switch on the control circuit power supply only. Refer to the following page for information on
connecting I/O signals.
Page 43 Example I/O signal connections
• Check that a voltage exceeding 24 V DC has not been applied to the pins of the CN3 connector.
• Check that the plate and DOCOM of the CN3 connector have not been shorted.
