Using the local command push-button
With the local command push-buttons (figure A) you can control cyclic ON/OFF switching
over, reversing the status of the relay each time it is pressed.
If a priority command is active, the local commands will not be executed.
ATTENTION: the local command push-buttons will only work if BUS voltage
is present.
Behaviour of supply fall/reset on the bus
If BUS voltage drops below 18 V dc for more than 1,5 ms the actuator, with the factory
default settings, will not carry out any changes to the status of the output contacts.
The behaviour of the outputs when BUS voltage drops can be configured in the following
way.
Configuration mode input:
• press the programming key: the red programming LED turns on
• press the local command push-buttons 1 and 4 simultaneously for at least 3 seconds
• wait until the 4 LEDs blink once
When you are in the configuration mode, the contacts of all the channels are opened and
the LEDs show the current configuration status of each single channel, as per the table.

The setting of each single channel can be changed with its relative key, so as to scroll
all the configurations available in sequence.
