3.3.12 Analog Inputs (0 to 2000 Ohm | 0/4 to 20 mA | 0 to 1 V)
It is recommended to use two-pole analog senders for best possible accuracy.
Connect the resistive analog input's return wires (GND) always to Engine Ground
(terminal 15) and as close to the easYgen terminals as possible.
For two pole senders of 0/4 to 20 mA or 0 to 1 V sensors Engine Ground is no "must
have".
The following curves may be used for the analog inputs:
• Table A •
• Table B •
• Linear •
• Pt100 •
• Pt1000 •
• AB 94099 •
• VDO 120° C •
• VDO 150° C •
