§6 Troubleshooting
6-1 [POWER] indicator lamp does not light
1) Check the primary power supply.
2) Check if the metal connector Co1 on the rear panel of the control unit is connected. (See 9-1 Wiring
diagram)
3) Check the power plug socket and power cord for their connection and breakage
4) Check if the fuse mounted on the rear panel of the control unit is not blown out. (The circular hole
of the fuse is displayed white if the fuse is blown out.)
6-2 [POWER] indicator lamp lights, but the specimen does not drop
1) Press [SET] switch and make sure that the specimen is set.
2) Check if the metal connector Co.2 on the rear panel of the control unit is connected. (See 9-1 Wiring
diagram)
6-3 Pneumatic pen cylinders don’t operate
1) Check if the metal connector Co.1 on the rear panel of the control unit is connected. (See 9-1 Wiring
diagram)
2) Make sure that air is fed from the pneumatic pressure source.
3) If the set value of the regulator of the tester is lower than 0.2MPa, the air pressure may leak from
the solenoid valve mounted on the specimen supporting base to cause the pneumatic pen cylinders
to be not operated. (This does not mean any trouble.)
In such a case, increase the setting pressure.
4) If the selector switch is selected to [DH>500mm], the proximity switch for detecting the specimen
supporting base during drop may be defective. Please contact us.
