temperature. 

 

Dust 
accumulates on 
the dust filter. 

Electricity 

The output voltage 
is normal. 

Multimeter 

The BLVD or 
LLVD voltage 
exceeds the 
threshold. 

For details, see 4.2 
Rectifying 
Common Faults.
 

Preventive 
maintenance 

Indicators are 
normal. 

By observation 

An alarm is 
generated. 

Exterior 

The paint or 
electroplated 
coating on the 
cabinet is intact. 

By observation 

The cabinet is 
damaged or 
deformed. 

Repaint and repair 
the shell. 

Grounding 

The ground point 
properly connects 
to the equipment 
room ground bar. 

By observation or 
by using a 
screwdriver or 
wrench 

The cable that 
connects the ground 
point and the 
equipment room 
ground bar is loose. 

Secure the ground 
point or replace the 
ground cable. 

 

4.2 Rectifying Common Faults 

4.2.1 AC Failure 

Possible Causes 

 

The AC input power cable is faulty. 

 

The AC input circuit breaker is OFF. 

 

The power grid is faulty. 

Measures 

1.

 

Check whether the AC input cable is loose. If so, secure the AC input cable. 

2.

 

Check whether the AC input circuit breaker is OFF. If so, handle the fault which caused 
the AC input circuit breaker to turn OFF and then switch on the circuit breaker. 

3.

 

Check whether the AC input voltage is lower than 50 V AC. If so, handle the power grid 
fault. 

4.2.2 AC Over Volt 

Possible Causes 

 

The AC overvoltage alarm threshold is incorrectly set on the SMU.
