3 TC OPERATION AND INTERFACE
3.1 Software function with RSP integrated safety module
When the RSP integrated safety module is used the procedures and software logic described in
the product manual
M8353-1 Integrated safety module shall be adhered to by the system
integrator installing the tool changer.
3.2 Software function without RSP integrated safety module
When RSP integrated safety module is not used the risk assessment for this tool changer
(locking control function and monitoring) requires that the, generalised, software logic described
below is adhered to by the system integrator installing the tool changer.
Valve control with two monostable 3/2-valves.
o
The right valve, called TC Close, will in passive position allow the air pressure to move
the piston in the direction locking the tool. In active position the air will be allowed to be
evacuated from the cylinder without impacting the piston.
o
The left valve, called TC Open, will in active position let the air pressure move the
piston in the direction unlocking the tool. In passive position the air will be evacuated
from this side of the cylinder, allowing the tool to be locked.
o
As a consequence, both valves must be activated to open the tool changer.
o
The “doOpen TC 2” signal shall be interlocked with both a tool attachment (TA) present
jumper and a tool stand switch indicating the following safe conditions for opening the
tool changer:
*
When there is no tool attachment mounted, the tool changer can be opened.
*
When there is a tool attachment mounted, it is only possible to open the tool
changer when it is positioned in the tool stand.
