Activation and setting values

The following signals can be connected to universal inputs X1...X5 at the SEZ220
signal converter:
• Passive analog signals.
Xx
LABEL
• Active analog signals.
x
Universal Xx inputs are always available. If not required for their functionality, they
can be used for diagnostics purposes.
To activate, assign each input used to a LABEL (identifier). The identifier also
defines the input's unit. The following identifiers are available:
LABEL (identifier) Explanation
TEMP Temperature sensor without any ready assigned functionality
(type), unit °C / °F.
% DC 0...10 V signal, unit %.
0.0 Universal input with 1 decimal, resolution –99.9...+999.9,
increment 0.1.
0000 Universal input with no decimal, resolution –999...+9999,
increment 1.
The following types (TYPE) care available for the identifier TEMP:
• NI (LG-Ni 1000)
• 2XNI (2 x Ni1000)
• T1 (T1)
• PT (Pt 1000)
• 0-10 (DC 0...10 V)
• Ohm (0...1000 Ω)
The type is always DC 0...10 V for identifiers %, 0.0 or 0000.
The measuring ranges for the passive temperature signals are defined as follows:
Temperature signal Measuring range
LG-Ni 1000 –50...+250 °C
2 x Ni 1000 or T1
Pt 1000
You can set the measuring range by entering a minimum and maximum value for
DC 0...10 V signals and 0...1000 Ohm resistance signals.
Example:
Room temperature with an active DC 0...10 V signal = 0...50 °C:
−
Minimum measured value (MIN VAL):
−
Maximum measured value (MAX VAL): 50 °C
You can enter a measured value correction (CORR) for passive temperature
sensors aimed at compensating line resistance.
This allows for on-site calibration using a reference measuring instrument.
