Figure 5-2 ACE3600 I/O Module – Front Panel (without TB Holder)
I/O Module LEDs
The ERR LED indicates an I/O module fault and errors. It will remain lit until all the errors
have been eliminated. Diagnostic and error messages can be retrieved from the module using
the ACE3600 STS Error Logger or SW Diagnostics. For more information, see the ACE3600
STS User Guide.
The I/O status LEDs in Digital Input (DI) and Digital Output (DO) modules indicate ON and
OFF (LED lit when the I/O is ON.) In Analog Input (AI) modules, each input has two LEDs,
indicating Overflow (OF) and Underflow (UF).
I/O Module Test
The I/O modules can be tested using the STS Hardware Test utility. For more information, see
the ACE3600 STS User Guide.
The I/O module LEDs can be tested using the STS Hardware Test utility– all the LEDS are lit
for a number of seconds, and then turned back to their previous state.
Panel Terminal Block (TB) Connectors
TB connectors have a fixed female side on the module and a male plug for the sensor/device
wire connection. The TB male side in all modules is screw type for up to 1mm (18 AWG)
wire. An optional TB extractor is available for easy removal of TBs.
