 Clothes that suitable for operation

 Safety shoes

 Helmet

Operating Notice
 Make sure there is no one in the safety fence when operating the robot. Meantime, please

check the potential hazards. You can ONLY operate when all the potential hazards are

cleared.

 Please touch the display and teaching pendant without gloves in case of the deviations.

 Please save the data at times in case of the loss of data accidentally. The information of

the programme and system variable number can be saved in the memory cards or floppy

Programming Notice
 Please keep the following things in mind if have to working inside the fences:

 Check and make sure there is no danger before go inside the fences.

 Make sure that E. STOP Button is at hand.

 Use the robot in low speed.

 Operate the robot in a clear mind in case not put the other operators in a danger condition

when there’s some commands or motions relate to peripheral equipment.

 The programming operator should be trained in related company properly.

1.1 Connection
Picture 1-1 refers to the samples of IL-HOST03 for host control unit;
IL-HSP-150SD02 for sensor:
A. Using the FUNCTION & LAN cable to connect the host control unit with the
sensor.
B. Using the cable to connect the robot control cabinet with the host control unit.
C. Connect the host control unit with power adapter to a stable power supply
( available voltage range: 100V~240V, Hertz: 50-60 Hz).
D. Connect the mouse and keyboard to USB.
E. Connect the air-cooling system of the sensor. Connect the FRL with the air
compressor; connect the vent tube with FRL and the sensor. Adjust the air
pressure to 100kPa. (Note: keep the air dry and clean).
F. The cabinet requires separate grounding.
G. The temperature of the sensor should be controlled within 5--40 degree.

B. This code is for base correction. The three parameters of

“XDirectCorr/YDirectCorr/ZDirectCorr/” are for the deviations of X/Y/Z direction
of each CD. The picture above shows the deviation of X direction of CD3,
deviation of Y direction of CD1 and deviation of Z direction of CD3 to correct
