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 Control Unit has a BUZZER inside:
The internal Buzzer sounds a Beep every touch of the keyboard, but it is possible to deactivate this
option from the settings (SETTINGS>>BUZZER). It can also be set to sound in case of Fault and /
or Alarm.
The Control Unit can store the Events:
The system can store up to 100 events (Alarms, Faults, Power ON, Mains blackout and Resetting),
that can be re-called at any time.
The Control Unit has an SD-CARD slot, it can be used for:
- Future updates of the Control Unit firmware.
- Loading or Saving the Control Unit configuration and the events.
- Transfer of a copy of the configuration from a CE424, to another CE424.
- Data Logger (Storing in time, of the values read by the sensors, in text format).
The Control Unit has 1 Modbus
With the expansion board ES415 (Optional PC-Card Modbus output) you can connect the Control
Unit to a Building or Industrial Management Systems, using the Modbus RTU binary protocol.
The Control Unit is protected by 3 LEVELS of PASSWORD:
Some menus 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: for the User
LEVEL 2: for the Installer or Maintenance technician.
LEVEL 3: Reserved - Only accessible for factory settings.
