All cables are intact and connected to appropriate connectors. 

 

The emergency stop button is attached to the control box and is located where the operator 
can reach it from his/her workplace at any moment. 

 

The operating conditions comply with the requirements as set forth in 

Section 1.5

. 

 

All risks identified during a risk assessment of the operating environment have either been 
eliminated  or  mitigated  by  implementing  appropriate  measures  (e.g.,  safeguards,  limiting 
access to the arm workspace). 

 

There are no obstacles within the workspace of the robotic arm that could prevent the arm 
from moving freely or operating properly. 

Now, the PULSE arm is ready for switching in accordance with 

Section 3.2. 

3.2

 

Switching the arm 

To start the PULSE robot, follow the sequence as below: 

1.

 

Plug the power cord of the control box into the mains socket. 

2.

 

Flip the external mains switch (if any) of your system to the ON position. 

3.

 

Flip the power switch on the back panel of the control box to the ON position. 

 

The control box starts receiving power and initializing. The green LED on the control box is 
blinking, while the LED on the arm wrist is off. 

Once the bootup of the control box is over, the green LED goes from blinking to steady green. 
Then, the arm starts initializing, too. After the arm initialization is over, the wrist LED turns 
steady green, and the arm goes into the READY state. 

 

Do not move the arm until the initialization is over and the wrist LED on the arm is 
steady green. 

Now, to be able to control your PULSE arm, you need to set up communication between it and a 
PC or other control device as detailed in 

Section 3.3

.

Setting up communication with a PULSE arm 

To set communication with a PULSE arm, you can use:
