Advice regarding the installation of temperature sensors:
①Only original factory equipped Pt1000 temperature sensors are approved for using with
the collector, it is equipped with 1.5m silicon cable and suitable for all weather
conditions, the cable is temperature resistant up to 280oC, connect the temperature
sensors to the corresponding terminals with either polarity.
②Only original factory equipped NTC10K, B=3950 temperature sensors are approved for
using with tank and pipe, it is equipped with 3m PVC cable, and the cable is temperature
resistant up to 105oC, connect the temperature sensors to the corresponding terminals
with either polarity.
③All sensor cables carry low voltage, and to avoid inductive effects, must not be laid close
to 230 Volt or 400 Volt cables (minimum separation of 100mm).
④If external inductive effects are existed, e.g. from heavy current cables, overhead train
cables, transformer substations, radio and television devices, amateur radio stations,
microwave devices etc., then the cables to the sensors must be adequately shielded.
⑤Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s
length is up to 50m, and then 0.75mm2cable should be used. When cable’s length is up
to 100m, and then 1.5mm2cables should be used.
