6.10 REMOTE CONTROLS
6.10.1 Remote ON/OFF
The dryer can be remotely started and stopped (REMOTE ON/OFF). Proceed as follow to activate this function:
1. Disconnect the dryer from electrical supply and open the electrical box.
2. Remove the bridge between the two terminal blocks marked with “ON/OFF” (See electric wiring diagram – wires 14 and 10).
3. Connect the “ON/OFF” terminal blocks to remote a unipolar switch.
Remote ON/OFF digital input is configured as follow: close contact = dryer ON.
When the dryer is switched off using remote OFF command, the controller shows on upper display line
the message “OFF” and the remote ON/OFF led blinks.
The remote OFF function disables the ON function from the dryer’s control board (until the ON function
is activated from remote ON/OFF switch). To restart the dryer it’s necessary to operate on the remote
control.
The activation of the above function is at the user’s discretion. The user will purchase all necessary
installation materials himself. Any operation which needs access to the dryer must be carried out by
qualified personnel.
6.10.2 Remote signalling alarm
The dryer control board is supplied complete with a digital output configured as remote signalling alarm. This digital output is controlled
by a relays configured as normally open: when an alarm is detected, these relays close a circuit. The status of the relays can be
inverted, if necessary, using AL18 programming parameter (See 6.6.2 Parameters table).
Proceed as follows to activate a remote alarm output:
1. The User must provide a signaller in compliance to output relays electrical features (solenoid coil, light bulb, acoustic signaller,
...).
2. Disconnect the dryer from the electrical supply and open the electrical box.
3. Connect the signaller on “REMOTE ALARM” terminal blocks (See electric wiring diagram – wires 25 and 26).
The activation of the above function is at the user’s discretion. The user will purchase all necessary
installation materials himself. Any operation which needs access to the dryer must be carried out by
