FT-70 Fill Level Inspector Service Manual

9-8

Remote Alarm

The FT-70 Remote Alarm option uses the Diagnostic Error signals 
to latch (hold LOW or SINK) the appropriate PLC output lines. 
Each Remote Alarm is initiated by a diagnostic error number (or 
group of error numbers) and remains latched until the diagnostic 
error number is cleared. 

The Remote Alarm Option and the PLC Interface Option may be 
used in the FT-70 simultaneously, however they may not occupy 
the same signal output lines. To determine the signal output 
wiring in your FT-70 see 

How to Determine the Signal Output 

Wiring

 in the previous section.

How to Clear a Remote Alarm

A Remote Alarm is cleared when it is overwritten by another 
alarm, or when the operator manually clears the alarm.

To clear the alarm manually:

1.

Press Key 6 and the error appears in the control panel display.

2.

Press the Arrow Key to clear the error.
