Extend Analog Output Range
Use the AOVER command to allow the analog output channels to
exceed their specified range by 10%. The scaling of the parameter
remains as before; the extra range is used for additional measurement
range in the high end of the scale.
AOVER [ON/OFF]<cr>
Example:
>aover on
Extended output: ON
>
The following example illustrates how the analog output is affected.
Channel 2 outputs temperature (T) with voltage output 0 … 5 V
(0 … 60 °C). After giving the AOVER ON command, the range is
0 … 5.5 V (0 … 66 °C). Note that the 60 °C point is still at 5 V.
Operation of Relays
Quantity for Relay Output
A relay monitors the quantity chosen for the relay output. Any of the
quantities available can be chosen.
Measurement-Based Relay Output
Modes
Relay Setpoints
When the measured value is in between the "above" and "below" values,
the relay is passive. When choosing lower value as "above" value and
higher value as "below" value, the relay is passive when the measured
value is not between the setpoints. You can also set only one setpoint.
See Figure 69 on page 129 for illustrative examples of the different
measurement-based relay output modes.
