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.
