IMPORTANT
Read this document thoroughly before installation and
before use of the device and follow all recommendations;
keep this document with the device for future consulta-
tion.
Only use the device in the way described in this document;
do not use the same as a safety device.
The device must be disposed of in compliance with
local Standards regarding the collection of electric
and electronic equipment.
1 DIMENSIONS AND INSTALLATION
1.1 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 (temperature
of use, humidity, etc.) lie within the limits indicated;
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, me-
chanical vibrations or shocks.
- any metal parts in proximity of the control module must
be at a distance such that they do not compromise the
safety distances.
- 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.
2 ELECTRIC CONNECTION
2.1 Warnings for the electric connection
- do not use electric or pneumatic screwdrivers on the
device terminal board
- if the device has been taken from a cold to hot place,
humidity could condense inside; wait about 1 hour
before powering it
- make sure that the power supply voltage, the frequency
and the operational electric power of the device,
correspond with those of the local power supply; see
chapter 13
- disconnect the device power supply before proceeding
with any type of maintenance
- position the power cables as far away as possible from
the signal cables
- for repairs and information regarding the device, contact
the EVCO sales network.
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 param-
eter 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 “shut-
down” means the passage from “on” status to “stand-by”
status.
When the power is switched back on, the device dis-
plays the status that it was in at the time it was discon-
nected.
3.2 Device switch-on/off in manual mode
Operating Statuses:
1. Make sure that the keyboard is not locked and that no
procedure is in progress.
2. Hold the key down for 2 s: the LED will switch off/on.
Using the digital inputs it is also possible to remotely switch
on/off the device.
3.3 The display
If the device is switched on, during normal operation, the
display will show the cell temperature, except during
defrosting, when the device will show the temperature
established with parameter d6.
If the device is switched off, the display will be switched
off.
