Each Sensor can be configured in two ways:
Preconfigured Setup
: Here you can choose one of the models of our production, (
See list in Table
on page 35
), which is then automatically set in the configuration recommended by the respective
thresholds and relay outputs. Is enough set the output number (relay) to complete the
configuration. The manual changes are, however, permitted.
General Configuration
: Here you can configure any type of sensor (
compatible or a new model
not yet listed
), manually entering all parameters.
•
The AUX input is configurable and can be associated with a relay output:
- Can be configured to activate one of the available relays and can be used by devices with NO or
NC contact outputs (
gas sensors with a relay contact, smoke sensors, buttons, etc.
).
•
The CE408 can manage up to 5 or 9 Alarm relays:
Each sensor has three alarm levels (
Threshold 1, Threshold 2 and Threshold 3
) and a
FAULT
,
freely addressable to any relay output.
•
The alarm thresholds can be configured with special mode of operation:
For use in car parking "
PARKING EN
" (EN 50545-1) or to the workplace, such as exposure limit
value
TLV
.
•
Each output (relay) can be configured as follows:
-
Silenceable
: the output is disabled for the
Silence time
, when
RESET
is carried out and the
sensor is above the set threshold. This function can, for example, be used for the outputs
connected to audible warning devices.
-
Silence Time:
is the time,
adjustable from 0 to 300 seconds
, so
Silenceable output
(
e.g. relay connected
to a siren
) is disabled when the
RESET
is performed and a sensor is above the set threshold
-
Hysteresis ON
: is the delay,
adjustable from 0 to 300 seconds
, of the relay, associated with an alarm
threshold.
-
Hysteresis OFF:
is the delay,
adjustable from 0 to 300 seconds
, of the relay to return to normal
condition, when it ends the alarm.
-
Time ON
:
is adjustable from 0 to 300 seconds
. This function can only be used if you want to stop the
alarm output after a finite time, even if the sensor remains above the alarm threshold set (
This
function cannot be used in conjunction with
Hysteresis OFF
delay
). For example you can use it
to enable devices that cannot be powered down, or to send a pulse to a phone dialer.
-
Memorized
: the relay remains in alarm, even if the sensor returns below the threshold (
this
function does not work if the
Time ON
or into
Hysteresis OFF
has already been inserted a value
other than zero
), to return to normal conditions must be done
RESET
. Serves, for example, to
prevent the accidental or unauthorized resetting of a block valve of the gas, without first checking
the cause of the alarm.
-
Positive Logic
: the operation of the relay can be set normally activated or in positive logic,
therefore, if the relay fails, or is completely out of power, automatically moves into the Alarm
position, the NC contact becomes NO.
•
The CE408 have a BUZZER inside:
The internal
Buzzer
sounds a
Beep
every touch of the keyboard. It can also be set to sound in
case of Fault and / or Alarm.
•
The CE408 can store the Events:
The system can store up to 100 events comprising Alarms, Faults, Power ON, Mains blackout and
Resetting, that can be re-called at any time.
•
The CE408 has an SD CARD slot:
It can be used for future updates of the central unit firmware.
•
The CE408 is protected by 3 LEVELS of PASSWORD:
The functions of the control panel are accessible up to three password levels, with a code
composed of 4 numbers. The levels are for access to functions, used by the respective authorized
persons.
LEVEL 1
: User / User
LEVEL 2
: The Installer / Maintenance technician
LEVEL 3
: Manufacturer / the assistance technician.
