2.5 TSI Operational Function
The TSI system provides safe operation, by preventing the Tool Changer from unintentionally unlocking
when the Tool is attached and not secured in the tool stand. The following sections describe the Tool
Changer states and how the TSI system controls the unintentional unlocking of the Tool Changer.
2.5.1 The Master is Free of the Stand and the Tool is in the Stand
The Master is positioned away from the tool stands, and all the Tools are safely nested in the tool
stands.
When there is no tool present (therefore both the RTL sensors are low) the RTL Relay allows the
Unlatch solenoid circuit to be completed and an Unlatch command is processed.
2.5.1.1 RTL Bypass Relay Circuit
The Master module has a normally closed RTL bypass circuit (RTL relay). If the Tool
Changer is inadvertently locked without a Tool attached, the Tool Changer can still be
safely unlocked automatically since no Tool is present. When a Tool is present (and
therefore the RTL sensor is high) the RTL Relay is energized and the Unlatch solenoid
circuit is diverted through to the Tool side. The second set of RTL relay contacts
sources US1 power and provides the RTLV input for health status monitoring of the
RTL Relay.
