Processor Operation in Case of Blown Fuse - Processor Faults

The Processor Fault position for JP1 is shown on the following page. 

For this JP1 configuration, the processor generates a nonrecoverable error for all SLC 500 processors. 

For a nonrecoverable error, note the following:

• Processor operation halts and the processor fault light flashes.

• All outputs are reset to OFF.

• The processor major fault bit S:1/13 is set.

• Monitor processor status file word S:6 for error code xx58 for SLC 500 and

5/01 processors, and error code xx60 for SLC 5/02 and later processors.

IMPORTANT

The 1746-OB6EI and 1746-OB16E modules perform auto-reset under 

overload conditions. When an output channel overload occurs, that channel

will limit current within milliseconds after its thermal cut-out temperature

has been reached. While in current limit, the output channel can cool below

the thermal cut-out temperature allowing the module to auto-reset and

resume control of the output channel as directed by the processor until the

thermal cut-out temperature is again reached.

Removing power from an overloaded output channel would also allow the

output channel to cool below the thermal cut-out temperature, allowing

auto-reset to occur when power is restored. The output channel would

operate as directed by the processor until the thermal cut-out temperature is

again reached.

To avoid auto-reset of an output channel under overload conditions, an

external mechanical fuse can be used to open the circuit when overloaded.

Heat Dissipation

The following tables contain values for the heat dissipated by each I/O module.

Use them to calculate the total amount of heat dissipated by your SLC 500 control system.

For details on how to calculate total heat dissipation, refer to the SLC 500 Modular Hardware Style User Manual, publication 1747-UM011.

Please note the following definitions:

• Watts per point - the heat dissipation that can occur in each field wiring point when energized at nominal voltage.

• Minimum Watts - the amount of heat dissipation that can occur when there is no field power present.

Install the Chassis Interconnect Cable (optional)

To connect up to three chassis together (for a maximum of 30 I/O slots), install the chassis interconnect cable before attaching your power supply.
