Connect the shielding of the sensor cable to the earth faston connector of the S1 unit.
6.3.8 ACM type 7: PT1000 temperature sensor (-50…+250 deg C)
PT1000 temperature sensors have a resistance varying with the temperature. When the
temperature is 0°C (32°F) the nominal resistance is 1000 ohm. At 200,4°C this
resistance is raised to 1760 ohm.
Use PT1000 sensors with a mean temperature coefficient
α
of 0.003850
ΩΩ
-1
°C

. In
case of doubt please contact your sensor supplier. (reference: IEC Publication 751)
The wires to a sensor must be as short as possible and with a big enough section, to
reduce wire resistance errors.
The wires of a PT1000 sensor of the same color have to be kept together if the sensor
has more than 2 wires.
Connect the shielding of the sensor cable to the earth faston connector of the S1 unit.
