Key to Figs. 4.d and 4.e:
1 probe CAREL 1
2 CAREL probe 2 (if available)
3 remote ON/OFF (contact closed= humidi er enabled; contact open=
humidi er disabled, in standby)
If non-CAREL probes are used, check:
voltage signal: 0 to 1 Vdc, 0 to 10 Vdc, 2 to 10 Vdc, terminal M2.1 (GND:
M2.2);
current signal: 4 to 20, 0 to 20 mA, terminal M2.4 (GND: M2.6).
In addition, depending on the type of power supply:
+15 V, terminal M2.3;
+ 1 Vdc 135 ohm, terminal M2.4.

Important:
to avoid unbalanced control, the earth of the probes or the external
control devices must be connected to the earth of the appliance’s
controller.
For the operation of the humidi er, M2.7 and M2.8 must be connected
to the “remote ON/OFF” via an enabling contact or alternatively
jumpered (default solution). If these terminals are not connected, all
the internal and external devices managed by the controller will be
disabled, with the exception of the drain pump for emptying the unit
after extended periods.

Note: in industrial environments (IEC EN61000-6-2), the cables
leaving the unit must not exceed 30 m in length, except for the
room probe (terminals M2 pin 1-2-3-4-5-6), the remote on/o digital
input (terminal M2 pin 7-8) and cable shields for RS485 communication.

Electrical speci cations: 250 Vac; Imax: 2 A resistive 2 A inductive.
Note: use clamps on the signal terminal blocks (alarm, utilities) to
prevent the cables from being detached.
4.6 Utility connections (light, fans,
sanitisation, essences)
The humidi er features of a terminal block for connecting the utilities,
located under the electronic board (see the following  gure for the
connections).
Depending on the type of connection, the required voltage is made
available for the outputs to the utilities (12 V, 24 V, 230 V or voltage-free
contact).
