5. Diagnostic Functions and Error Handling
There are several diagnostic functions that can have an effect on the input bitmap and influence the Tool
Changer control.
5.1 Power Status
The DKG module continuously monitors the voltage of its interface and sensor power supply. If the
voltage is between 11V and 25V the “Input and Logic Power Good” bit will be high. If the voltage falls
outside of this range the “Input and Logic Power Good” bit will be low and will remain low until the
voltage is between 11V and 25V and the Clear Errors output has been set from low to high.
Note: The Tool Changer will not Unlatch while the “Input and Logic Power Good” bit is low.
5.2 Valve Power Status
The DKG module continuously monitors the voltage of the Ouput power which is used to supply the
lock and unlock solenoid valves of the Tool Changer. If the voltage stays above 21V the “Valve Power
Available” bit will be set high. If the voltage falls below the 21V threshold the bit will be set low. It will
become high again as soon as the voltage rises above 21V.
5.3 Error on Latch or Unlatch Output
The valve control outputs of the DKG module are protected against overload conditions such as those
created by a short circuit. During an overload condition the LATCH and/or UNLATCH output is turned
off and the corresponding error bit “Error on Latch Output” or “Error on Unlatch Output” is turned on.
The output cannot be set high again until the overload condition is removed and the “Clear Errors” bit is
set from low to high.
5.4 “COMM OK” bit
The “COMM OK” is set high as soon as Ethernet/IP communication is established.
5.5 “Tool Power is On” bit
The “Tool Power is ON” bit is set high when the Arc Prevention Circuit has activated power on the
Tool-side. If this bit is low there will be no power available on the Tool.
5.6 “Unlatch Enabled” bit
The “Unlatch Enabled” bit is set high when the DKG module determines that the necessary
preconditions for unlatching the Tool have been met (Tool is in the Tool Stand, etc.). A Tool can only
be released if the “Unlatch Enabled” bit is high. For additional details refer to
Section 3.4—Tool-Side
