Interlock Relay Operation Example
Relays 1 & 2 are configured to energize (their front panel LEDs are off)
when SW1 & SW2 switches (above) are closed. If the contacts to these
digital inputs are opened, the corresponding front panel LEDs flash,
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 inputs (switches).
Note: If multiple digital inputs are assigned to the same relay, then the
corresponding logic is (AND) – i.e. both switches must be closed to trip
the relay.
Scaling the 4-20 mA Analog Output (Aout)
The 4-20 mA analog outputs can be scaled to provide a 4-20 mA signal
for any display range selected. To select the channel and source
assignments the analog outputs are assigned to, see Analog Output
Source on page 73.
No equipment is needed to scale the analog outputs; simply program
the display values to the corresponding mA output signal.
The Analog Output menu is used to program the 4-20 mA outputs
based on display values.
For instructions on how to program
numeric values see Setting Numeric
Values, page 34.
