DESCRIPTION
•The CE408P Gas Control Unit are wall mount housing 280x230x145 mm:
•The CE408P can be connected to all of our Gas Detectors (Sensors):
The CE408 can control up to 4 or 8 remote gas sensors.
- Three-Wire, 4÷20mA linear output models with “Replaceable Cartridge Sensor” for:
Flammable gases with Catalytic sensor TS292K(IP65) or TS293K(Ex”d”) series with 0÷20%LEL range.
Flammable gases with Pellistor sensor TS292P(IP65) or TS293P (Ex”d”) series with 0÷100%LEL range.
Flammable gases with Infrared sensor TS293I(Ex”d”) series with 0÷100%LEL range.
Toxic gases with electrochemical cell TS220E (IP65) or TS293E (Ex”d”) series.
Carbon dioxide with Infrared sensor TS220IC2 (IP65) or TS293IC2 (Ex”d”) series.
Oxygen with electrochemical cell TS220EO or TS293EO (Ex”d”) series with 0÷25%O2range.
With dual sensor for Parking TS255CB or TS255CN2
- Should be connecting all models without the replaceable Cartridge:
Flammable gases with Catalytic sensor ST441 (IP65) or SE193K (Ex”d”) series.
Carbon dioxide with Infrared sensor IR101 or IR102 series.
Should be connecting all models produced up to December 2008. Three-wire 4÷20mA linear
sensors for flammable gas or two-wire 4÷20mA linear sensors for toxic gases and oxygen.
Inputs are configurable for 4÷20mA sensors with referred current to ground and operating
characteristics same as our products (unit in %LEL or ppm, minimum operating voltage,
absorption, load resistance etc.).
We accept no liability for any malfunction, failure or damage caused by products not
compatible or not we produce.
•Each Sensor may be associated with a ZONE:
The sensors can be grouped into Zones (Max 2), which can associate up to 2 relay outputs
different for each alarm level and a FAULT.
•Each ZONE can be set according to operating 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 function only for Italy (Italian Ministerial
Decree 01/02/1986).
•Each INPUT (Sensor) is self-protected 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 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.

THE FOLLOWING INSTRUCTIONS DESCRIBES ALL THE CENTRAL SYSTEM
SETUP PROCEDURES AS WELL AS THE INSTALLATION PROCEDURES TO
BE EXECUTED ONLY BY AUTHORISED AND EXPERIENCED PERSONNEL.
CE408P INSTALLATION
The CE408P should be mounted on the wall using 3 screws and wall plugs (Ø 6 mm) or 3 M4 screws
and nuts, if the wall is not in masonry. The housing's base must be fixed through the 3 holes, one in
the center and the other in the bottom corners (Fig.2). The electrical connections should be executed
all on the housing base.
Inside the housing, it can also accommodate two 12V/1.3Ah Lead batteries connected in series (Fig.3) to
assure the system powering in case of mains blackout. The battery life is about 30 minutes with 8
sensors. (The batteries are not included in the delivery, but are available on request).
If required, to increase the autonomy (1 hour), it can be used two 7Ah batteries connected in
series, but causes the greatest dimension, shall be installed in a case outside the CE408P.
ELECTRICAL CONNECTIONS
The electrical connections should be executed all on the housing base.
To simplify installation, the housing cover may be detached from the base, by disconnecting the flat
cable, press on the two tabs on each side as shown in Fig. 3. To reconnect, simply push the flat cable
into the connector respecting the polarization, the two locking levers will close automatically.
The details of the connections to the mains, the two batteries, the AUX input and relay output
R9 are illustrated in Figure 3. While the details of the connections to the sensors and the other
outputs are illustrated in Figure 4.
The terminals are of "polarized inlet" type (1). We suggest to use lugs adequate to the
conductors (2) and to fix the wires to the box structure to avoid excessive stress to the circuits
and to the terminals. Use a screwdriver (3) of the right dimensions.

P WER C NNECTI N
Mains Power Supply (90÷264Vdc / 47÷63Hz) should be connected to terminal L, N and Earth at the
bottom of the housing base. The terminal has a protective fuse (5x20) 2A.
The two 12V/1.3Ah Lead batteries if required should be connected in series to BAT+ (Red) and BAT-
(Black) terminals. For the series connection, use the black cable supplied with two terminals (4mm
Fastens).
The auxiliary input (AUX) can be used to connect devices with a NO or NC contact (gas sensors with
relay contacts, smoke sensors, buttons, etc.). It can be configured to activate one of the available
relays. It can be connected to multiple devices if it’s are homogeneous. (If the device has an NC
contact must be connected in series or in parallel if its have all a contact NO).
Output Relay 9 has the same characteristics and use of those described on the next page.

CONNECTION WITH GAS SENSORS
Please see the specifics User’s Manuals of the gas sensors.
Please note, that the CE408 has a board with 4 inputs and a board with 4 outputs. In Central
can be installed, a board ES404 and ES414 to have a total of 8 inputs and 9 outputs. The
diagrams, for simplicity, show all the 8 sensors and all relays outputs.
Sensors connection, with three-wire 4÷20mA transmitters, should be performed on the inputs board,
mounted in the base, on the left. The input terminals, “+, - and “S” should be connected to the
corresponding terminals of the sensor.
The connection wire section between the CE408 and the
sensors should be suitable to the distance, as shown in the
table. The connection needs a shielded cable. Shield
should be connected only to the central unit side, and on an
only point of EARTH that has to be equipotential.
The outputs connection, (Relays) should be performed on
the outputs board, mounted in the base, on the right. The relay output 9 is located on the central
board, see Figure 3. The nominal load of relay is 250 VAC - 2 A or 30 VDC – 2 A (resistive load).
The relay have changeover free voltage contacts, on the boards, indications NA means NO (Normally
Open), NC (Normally Close ), C(Common), refer to the relays in the normal position (not powered). If an
output is configured as POSITIVE LOGIC, the NO contact will become NC and NC will become NA.

The details of the individual items is as follows:
•FAULT: Indicates the number of active relays, relative to
exceeding the threshold of a fault (current <1 mA or> 24 mA), of a
sensor or a group of sensors that belong to a zone.
•AL 1: Indicates the number of active relays, relating to exceeding
the threshold of alarm 1, of a sensor or a group of sensors that
belong to a zone.
•AL 2: Indicates the number of active relays, related to exceeding
the threshold of alarm 2, of a sensor or a group of sensors that
belong to a zone.
•AL 3: Indicates the number of active relays, relating to exceeding the alarm threshold 3, of a
sensor or a group of sensors that belong to a zone.
•INPUT. : Indicates the number of active relay, logic input.

CONFIGURE (Level 2): There are two ways to configure a sensor.
The first allows you to choose between those preconfigured sensors,
the second allows a generic configuration. -----------------------------------
In the first case, you can configure only the models of our production (see
list in Table on Page 35), which have some parameters fixed (non-editable)
and other editable, all have already been set, including the configuration
of the outputs.
In the second case, you can manually enter all the parameters, which are
freely editable.
For safety, the outputs are configurable only when configuring or changing a sensor, a logic
input or a zone.
You cannot configure the outputs separately.
Configuring PRECONFIGURED SENSOR: To proceed with the
configuration, press
ENTER
on the relevant item highlighted.
Then, using and keys and pressing
ENTER
you can choose the
sensor’s number to be configured. ------------------------------------------------
To configure a dual sensor (TS255 series), you must use two
consecutive sensors (1-2, 2-3, 3-4, etc.); starting with the first of
the two. You cannot start from the sensor n. 8.
Then you can choose the model number.
The code of our products consists of 2 letters followed by 3 numbers,
and, if necessary, by other letters (2 to 4).---------------------------------------
To choose the desired one, is followed the same structure, must be
chosen before the first two letters, then 3 numbers and then the other
letters (if present).
With and you can scroll between the groups of letters and
numbers that make up the model, with
ENTER
you can confirm your choice
and move on. With
ESC
you can go back.
Example: for model TS292KM, first select TS and confirm by pressing
ENTER
. Then select the second item TS292 and confirm with
ENTER
key.
Finally complete the selection by selecting the complete entry TS292KM
and confirm with.
After choosing the model, its configuration is automatically loaded. ------
To scroll through the different items, use and keys. Pressing
ENTER
on the item, the value is highlighted to indicate that it is editable.
Use and to change the value, using and you change
from to another field in the same row (where applicable).

Description of items related to the Preconfigured sensor:
TAG: It is a TAG than 10 characters, selectable one at a time, where you can write a note or a
reminder for a sensor (e.g. FLOOR 2, BOILER, etc.).
AL.: Defines the type of ALARM of the sensor and establishes how they should be set the
thresholds of the various alarm levels. In the specific:
•INCREASING: The alarm levels will be set in ascending order, i.e. SENSOR
SCALE ≥ALARM 3 ≥ALARM 2 ≥ALARM 1 ≥FAULT (current <1mA). All our sensors, except
for the detection of oxygen, are set with this type of alarm.
•DECREASING: The alarm levels must be set in descending order, i.e. FAULT
(current <1mA) ≤ALARM 3 ≤ALARM 2 ≤ALARM 1 ≤SENSOR SCALE. Only our sensors to
detect oxygen are set with this type of alarm.
•OXYGEN: The alarm levels should be set to detect deficiency or excess of the
normal presence of oxygen in the air (20.9% v / v), i.e. FAULT (current <1mA) ≤ALARM 2 ≤
ALARM 1 ≤20.5% volume and 21.5% volume ≤ALARM 3 ≤SENSOR SCALE. Our sensors to
detect oxygen can be set with this type of alarm.
Alarm 2 is displayed as AL

,while the alarm 3 as AL

.
•TLV: (Threshold Limit Values) are the exposure limit values for toxic substances to
which workers may be exposed every day for the entire duration of working life without harmful
effects. Must be set in ascending, i.e. SENSOR SCALE ≥ALARM 3 ≥ALARM 1 ≥ALARM 2 ≥
FAULT (current <1 mA). In this case, each alarm level is a value obtained with a temporal
average. TLVs in detail are:
oALARM 1 = TLV-TWA (Time-Weighted Average)is
the time-weighted average concentration for a conventional 8-hour workday and a 40-hour
workweek, to which it is believed that nearly all workers may be repeatedly exposed, day after
day, without adverse effect. This alarm is triggered when the weighted average concentration
within 8 hours exceeds the set threshold.
oALARM 2 = TLV-STEL (Threshold Limit Value–
Short-Term Exposure Limit)is the concentration to which it is believed that workers can be exposed
continuously for a short period of time without suffering from irritation, chronic or irreversible
tissue damage, or narcosis. STEL is defined as a 15-minute TWA exposure, which should not
be exceeded at any time during a workday. This alarm is triggered when the weighted average
concentration in the last 15 minutes, exceeds the set threshold.
oALARM 3 = TLV-C (Threshold Limit Value-Ceiling)is
the concentration that should not be exceeded during any part of the working exposure. This
type of alarm is triggered when the instantaneous concentration exceeds the set threshold. Are
not carried out, time weighted average.
Only our sensors for detection of toxic gases can be set up with this type of alarm.
•PARKING EN:The alarm levels should be set so increasing, i.e. SENSOR
SCALE ≥ALARM 3 ≥ALARM 2 ≥ALARM 1 ≥FAULT (current <1 mA). In this case, the first
two levels of alarm representing a value obtained with a time average between 5 and 60 min.
(according to standard EN 50545-1 for the car parks). This value can be set via the parameter
TWA. Level 3, however is instantaneous.
This type of alarm (see Table 3) can only be set with our sensors for toxic gases in car parks car
(series TS220 and TS293 / EC/EN/EN2) or the dual sensors (series TS255).
•ZONE: Sets the area that will be associated with the sensor. The areas available are
2. The area 0means that the sensor is not associated in any area
•TWA: This parameter can only be changed in the sensors where the alarm is
PARKING EN (in all other cases is fixed at zero). Is how many minutes are carried out time-
weighted average for the activation of the 2 alarms? The value can be chosen between 5 and 60
min. (in accordance with standard EN50545-1 for the car parks).
•THRESHOLD: Indicates the value, above which, the corresponding alarm is
activated.
The thresholds have a hysteresis to prevent the output will cycle on and off continuously
(concentration fluctuates around the threshold value). This hysteresis is 20% of the value of the set
threshold, for all models of sensors. Only exception is for models for detection of oxygen

(TS220EO/TS293EO) whose hysteresis is 2%. The level of fault (FAULT) has a hysteresis of
1mA, so a sensor failure comes out when his current exceeds 2mA.

Description of the items relating to the outputs:
OUTPUT N.: Indicates the number of the output (relay). The configurable outputs ranging from 1-9.
The output of 0indicates that there is no output associated with that alarm level.
If the output boards are not properly connected or mounted, for safety, the
corresponding outputs cannot be configured.
•If the board ES414 is not connected to the terminal OUT 1-4 outputs will only be available
from 5 to 9.
•If the board ES414 is not connected to the terminal OUT 5-8 outputs will only be available
from 1 to 4 and 9.
•If it was not connected any board ES414, the only output available is 9.
•The outputs have to configure in a unique way. So, if you were choosing the same output for
different alarm levels will be considered valid, only the configuration of the higher alarm. You
cannot choose the same output for a level of alarm and fault
SILENCEABLE: Indicates that the output is disabled, the Silence time, when RESET is performed.
This function can be used for the outputs connected to audible warning devices
SILENCE T.: Indicates the Silence time (adjustable from 0 to 300 seconds), so Silenceable output
is cancelled by RESET.
DELAY ON: DELAY ON is the relay delay (Adjustable from 0 to 300 seconds) associated with an
alarm threshold.
If the alarm type was selected as PARKING EN and you were programming the output on the
threshold 3, this delay can only be set from 60 to 300 seconds.
DELAY OFF/TIME ON: The first item DELAY OFF (adjustable from 0 to 300 seconds), is the
relay’s delay, to return to normal status, when it ends the alarm condition. The second item,
TIME ON (adjustable from 0 to 300 seconds) can only be used to stop the alarm output after
a preset time, even if the sensor remains above the alarm threshold set. (It can be used to
activate devices that cannot be powered on or to send a pulse to a phone-dialer).
The two functions HISTER.OFF and TIME ON, cannot be used together, or with the SAVE
function. For safety, if the delay is set other than zero, the parameter stores will be
automatically changed to NO.
POS.LOGIC: Indicates that the output operation is in POSITIVE LOGIC or the relay is normally
activated, so, in case of failure automatically moves into the position of the alarm, and then
the NC contact becomes NO
LATCHED: Indicates that the relay remains in alarm, even if the sensor back below the alarm set.
To bring it back into the normal, RESET must be performer.
The function LATCHED, cannot be used simultaneously with DELAY OFF or TIME ON. For
safety, if the parameter LATCHED, was set YES, the parameters DELAY OFF and TIME ON,
will be automatically set to Zero
At the end of the screen is written SAVE to save the configuration entered. Pressing
ENTER
the
confirmation window will appear. Press again
ENTER
to confirm, or press
ESC
to go back and make
changes.
Only for double sensors, TS255 series, at the end of the screen, the message CONTINUE
appears. Because in this case, must be programmed two consecutive sensors. Only after the
second configuration, you can save the configuration entered.
If the set thresholds were in contrast with the criteria for this type of alarm
set, or if it had selected the same output for one of the alarm levels and
the Fault, a warning message will appear.---------------------------------------
Then the screen returns to the configuration of the sensor
