Page 14: Power Supply Connection
0.3% rH To avoid measurement errors due to the supply current, an additional power supply from an external transformer can be used (CAREL transformer codes TRA12VDE00 or TRA2400001), to be connected as shown in the figure (2’ with transf.). With this configuration the maximum distance is 100 m (note The transformer must not be earthed and can be installed in the panel together with the controller. -
Page 15: Functional Notes And Differences Between Dp And As Sensors (With Analogue Output)
Functional notes and differences between DP and AS sensors (with analogue output) On power-up, the DP sensors (excluding the serial and NTC temperature sensors) provide an output value (voltage or current) that is out-of-range (with a negative value), and that stabilises at the final reading in a maximum of 20 to 30 s. If the controllers feature alarm signals for readings that are out-of- range, such signals may be activated, however they are cancelled in the time indicated. -
Page 16: Table Of Main Variables-Parameters For Serial Sensors
The main feature of serial sensors is that they communicate data via the RS485 serial line (which can be configured by dipswitch). The parameters can be accessed via serial line using the Carel supervisor or Modbus protocols. The unit code of the board is 59 (MAC parameter) -
Page 17: General Warnings
4.10 General warnings • To maintain the index of protection declared in the versions with “IP55” case, the wiring must use multicore cables, with the outer sheath having a maximum diameter of 8 mm. • It is recommended to use shielded cables. The cables carrying the temperature and humidity signals must not run near the 115 to 230 or 400 to 480 Vac power cables, or near cables that power from the contactors to the loads. -
