• Each ZONE can be set acco ding to ope ating LOGIC:
The logic used are the typical logic functions (AND, OR), management of adjacent sensors
(CORR.CON, CIRC.CON). Note that PARK-ITA is a unction only or Italy (Italian Ministerial Decree 01/02/1986).
• Each INPUT (Senso ) is self-p otected and has a FAULT signal:
All sensors inputs are protected against short-circuit or wire breakings. If a short-circuit occurs,
the power supply to that input, is automatically stopped (all others continue to work properly). At
the same time, the FAULT signal is activated.
• Each Senso can be configu ed in two ways:
P econfigu ed Setup: Here you can choose one of the models of our production, (See list in Table
on page 4 ), 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.
Gene al Configu ation: Here you can configure any type of sensor (compatible or a new model
not yet listed), manually entering all parameters.
• The AUX input is configu able and can be associated with a elay 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 CE424 can manage up to 5, 9, 17 o 25 Ala m elays:
Each sensor has three alarm levels (Th eshold 1, Th eshold 2 and Th eshold 3) and a FAULT,
freely addressable to any relay output.
• The ala m th esholds can be configu ed with special mode of ope ation:
For use in car parking "PARKING EN" (EN 50545-1) or to the workplace, such as exposure limit
value TLV.
• Each output ( elay) can be configu ed 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 rom 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
- Hyste esis ON: is the delay, adjustable rom 0 to 300 seconds, of the relay, associated with an alarm
threshold.
- Hyste esis OFF: is the delay, adjustable rom 0 to 300 seconds, of the relay to return to normal
condition, when it ends the alarm.
- Time ON: is adjustable rom 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.
- Memo ized: 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 CE424 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.
