3 USER INTERFACE
3.1 Preliminary notes
Operating Statuses:
- "on" state (the device is powered and is on: the regulators
can be switched on)
- "stand-by" status (the device is powered but is switched
off via software: the regulators are switched off; the
possibility to manually switch on/switch off the cell light
or auxiliary output depends on parameter u2)
- the "off" status (the device is not powered).
Hereafter, with the word "start-up" means the passage from
"stand-by" status to "on" status; the word "shutdown" means
the passage from "on" status to "stand-by" status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.
1.2 User interface installation
Panel installation with snap-on brackets.
The following drawing shows the device installation process.
1.3 Installation warnings
- the thickness of the panel on which the user interface is
to be installed must be between 0.8 and 2.0 mm (0.031
and 0.078 in)
- make sure that the device work conditions (tempera-
ture of use, humidity, etc.) lie within the limits indi-
cated; see chapter 13
- do not install the device near to any heat sources (heating
elements, hot air ducts etc.), equipment containing
powerful magnets (large diffusers, etc.), areas affected
by direct sunlight, rain, humidity, excessive dust,
mechanical vibrations or shocks
- any metal parts next to the control module must be
placed at a sufficient distance to avoid reducing the
safety clearances
- in compliance with Safety Standards, the device must
be installed correctly and in a way to protect against
any contact with electric parts; all parts that ensure
protection must be fixed in a way that they cannot be
removed without the use of tools.
