P30P-09A 29 User's manual
Depending on the version, transducer can be equipped with an additional analog output (output #2) in
place of the alarm output using the terminals 13-14.
5.5.2.1. Individual characteristic of analog outputs
T30P transducer allows for processing measured values that are converted to output signal
based on the analog output linear characteristics. On the base of given coordinates of two points by the
user, the transducer determines (from the system of equations) coefficients a and b of the individual
characteristic.

5.5.2.2 Analog outputs overrun support
P30P transducer allows the user to configure the analog outputs to handle the overrun of the
defined threshold values. Overrun support is disabled by default – in such case, after the value
controlling the output is overrun, the output is still controlled proportionally to the controlling value outside
the basic output range. After the overrun support is enabled, user can define the output controlling value
in case of the maximum or minimum output value overrun.
Example: Main analog output 1 configuration
Output set to react to the value of averaged active power.
