Interlock Relay Operation Example
Relay 1 is configured to energize (the front panel LED is off) when SW1
or SW2 switches (above) are closed. If either of the contacts set in
series with the digital input open, the corresponding front panel LED
flashes indicating this condition. The processes being controlled by the
interlock relay will stop, and will re-start only after the interlock relay is
re-activated by the digital input (switches).
Scaling the 4-20 mA Analog Output (Aout)
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal
for any display range selected.
No equipment is needed to scale the analog output; simply program the
display values to the corresponding mA output signal.
The
Analog Output menu is used to program the 4-20 mA output based
on display values.
For instructions on how to program
numeric values see
Setting Numeric Values, page 28.
