Temperature errors in °C / K
The table below shows temperature errors, at an ambient
temperature of 20° C, depending on the line length and
conductor cross section for PT100 sensors.

Analogue output
5.1.2.9
The softstarter has one output for a configurable analog
output signal (terminals 29 and 30). The load resistance is
maximum 500 ohm for current output, and minimum 500
ohm for voltage output.
The output signal ranges available are 0-10 V, 0 – 20mA
or 4-20mA. The default setting is 4-20mA.
The analogue output has its own terminal for the positive
output, it is not shared with any other function on the
softstarter and it shall refer to the functional ground.
The analogue output can be selected to show:
I (A), U (V), P (kW), P (Hp), Q (kVAr), S (kVA),
cos Phi, Motor temp, SCR temp and Energy (kWh).
If the analogue output is used, the cables shall be
connected to terminals 29 and 30. See Figure 43.
See chapter 7 Function settings for programming.
The PTC input uses the same terminals as the
Analogue output and only one of these functions
can be used at the same time.
