E5
SI-T3 Watchdog Timer Error
The watchdog timed out.
Cause Possible Solution
Data has not been received from the PLC Execute DISCONNECT or ALM_CLR, then issue a CONNECT command or SYNC_SET command and
proceed to phase 3. Refer to the SI-T3 Option Technical Manual for more details on troubleshooting.
Digital Operator Display Fault Name
EF0
Option Card External Fault
An external fault condition is present.
Cause Possible Solution
An external fault was received from the
PLC and F6-03 is set to a value other than
3.
• Remove the cause of the external fault.
• Remove the external fault input from the PLC.
Problem with the PLC program Check the PLC program and correct problems.

Cause Possible Solution
An external device tripped an alarm
function
Remove the cause of the external fault and reset the fault.
Wiring is incorrect
• Properly connect the signal lines to the terminals assigned for external fault detection
(H1-oo = 20 to 2F).
• Reconnect the signal line.
