Solenoid short-circuit
When the short-circuited solenoid is desired to be driven.
Check whether the solenoid is short-circuited.
E811
Overvoltage
1. When voltage upper than guaranteed one is
1. Check whether the applied power voltage is higher than the rated v (plus)
inputted.
10% or more.
2. When 200V is inputted for 100V setting.
2. Check whether 100V/200V changeover connector is set by mistake.
In the above cases, POWER circuit board has broken.

Low voltage
1. When voltage lower than guaranteed one is
1. Check whether the votage is lower than the rated voltagw - (minus) 10% or less.
inputted.
2. Check whether 100V/200V changeover connector is set by mistake.
2. When 100V is inputted for 200V setting.
