4.3.4 ERROR ON UNLATCH1
This bit indicates that a short circuit or overload condition on the UNLATCH output to Valve 1 has
been detected.
The error condition can be reset with the Clear Errors bit.
4.3.5 ERROR ON UNLATCH2
This bit indicates that a short circuit or overload condition on the UNLATCH output to Valve 2 has
been detected. The error condition can be reset with the Clear Errors bit.
4.3.6 Lock/Unlock Sensor Fault
This error bit will be set if the Locked and Unlocked Sensors are on at the same time or if the latch/
unlatch motion of the Tool Changer is incomplete or faulty. If the condition is not on anymore then
the bit shall be automatically reset.
4.3.7 PRESSURE DISCONNECTED
The PRESSURE_DISCONNECTED bit indicates that the pressure sensor is disconnected and/or
that there are broken wires in the sensor cable.
If the pressure sensor is left disconnected then a SYSTEM_IS_UNSAFE error will be generated.
The error condition can be reset with the Clear Errors bit.
4.3.8 Pressure Too High
If the module detects the air pressure above 100 psi then the Pressure Too High bit is set. The error
can be reset by supplying air at the correct pressure and then applying the Clear Errors.
4.3.9 Pressure Too Low
If the module detects the air pressure below 60 psi then the Pressure Too Low bit is set. The error
can be reset by supplying air at the correct pressure and then applying the Clear Errors.
4.3.10 SYSTEM IS UNSAFE
Any safety related error (Application Processor communication errors, input/output mismatch
errors, safety switch error, valve error, etc.) will set the SYSTEM_IS_UNSAFE error. If the
SYSTEM_IS_UNSAFE error bit is set the UNLATCH and LATCH outputs shall be frozen. Refer
to
for the errors that will trigger a SYSTEM_IS_UNSAFE error.
The error condition can be reset with the Clear Errors bit.
4.3.11 TOOL-ID ERROR
The Tool‑ID shall be available to the Master within 250 ms from the time the changer is coupled;
otherwise a TOOL‑ID ERROR is set in the bit map. If the Master and Tool are coupled and the
Tool‑ID fails to be reported, a TOOL‑ID ERROR is set. The error condition can be reset with a
rising edge of TOOL PRESENT or the Clear Errors bit.
4.3.12 UNSAFE LATCH
A LATCH command shall only be performed if the following conditions are met:
• LATCH command is received
• UNLATCH bit is OFF
• US1 and US2 Power Present are ON
• PRESSURE_TOO_LOW and PRESSURE_TOOL_HIGH are OFF
• SYSTEM_IS_UNSAFE bit is OFF
If the LATCH command is received and the above conditions are not all met, the UNSAFE_
LATCH error bit shall be set. This error condition will be reset when a new LATCH command is
recieved and the LATCH_ENABLE conditions are met.
