● Please make sure that the input power supply voltage is equal to the rated voltage specification. There is a risk
of fire or accident.
●
Check the terminal arrangement and terminal symbols, please do not connect to the wrong line.
● Please do not do the withstand voltage test. There is a risk of damage.
● Please do not do the megger test for the control circuit. There is a risk of damage.
●
Please take measures to prevent the malfunction of the equipment and nearby sensors from electromagnetic
noise.
● Please do not apply strong shock to the product. There is a risk of accident.
●
Do not step on, or place heavy objects on the product. There is a risk of electric shock, accident or damage.
● Please place the product in permissible temperature and humidity ambient. There is a risk of malfunction and
shorter service life.
●
In order to exert a superior energy-saving performance, the hydraulic unit has a double-pump structure for
single and confluence switching by a solenoid valve. If the operating point of the machine is close to the
switching point of the solenoid valve, it is possible that the instability phenomenon may occur. In this case,
please change the settings of flow rate (qH) or pressure (PL) lower than the switching point (refer to page 12-3
[P13] ~ [P28]). It can also be stabilized by adjusting the width of the dead zone which is near the switching
point (refer to 12-3 or 12-4 [P29] ~ [P30]).
1.4.2
Operation
DANGER
●
Please do not touch the switch with wet hands. There is a risk of electrical shock.
● When the power is being supplied, please do not remove or insert terminals or change wires. There is a risk of
electrical shock, damage or accidents.
●
Please do not frequently turn on or turn off the power. There is a risk of accident.
CAUTION
●
Please set the pressure and flow rate in the permissible range of the machine. There is a risk of accident
● Before operation, please set the parameters according to the machine. There is a risk of damage or mechanical
failure.
●
Before operation, please make sure that it can be switched into emergency stop situation at any time. There is
a risk of damage or mechanical failure.
●
When the power failure occurs, the product may suddenly restarts after the power is restored, please do not
stay near the machine. There is a risk of injuries. Please adjust the machine to ensure its safety even restarting
it.
● If the power is turned off just for a while or the power is being supplied, because the electronic equipment and
heat dissipation fins may be very hot, please do not touch it. There is a risk of burns.
1.4.3
Maintenance and inspection
DANGER
● Only the qualified personnel can carry out the maintenance and inspection. There is a risk of electrical shock
or injuries.
●
Before operation please make sure the input power supply is OFF. There is a risk of electrical shock.
● Please make sure the motor is stopped, and the power supply is cut off for five minutes or more. There is a
risk of electrical shock.
●
When the power is being supplied, please do not remove or insert terminals or change wires. There is a risk of
electrical shock, damage or accidents.
CAUTION
● Please wear gloves and protective goggles when operation.
●
Please do not directly touch the controller board. It may be damaged by static electricity.
● Please do not do the voltage resistance test. The product may be damaged.
