3.3.2 Y Output Detection and Maintenance
1. After power on, use multimeter DC voltage to measure the voltage of Y port to COM, the
voltage is below 1V is qualified; after running, the voltage of Y port to COM is below
24±0.75V is qualified.
2. If the detected voltage value is abnormal, the Y terminal function is abnormal, check O6
and T2, replace the damaged components.

3.3.3 Relay Detection and Maintenance
1. TA-TC is normally open, TB-TC is normally closed, in case of failure, TA-TC is normally closed,
TB-TC is normally open.
2. TA-TB-TC output is abnormal, relay REL does not work, test O7, T1, REL2 is damaged.
