Introduction

The CE400 gas Central System has been designed to be connected to up to 4 sensors and
represent a useful instrument for monitoring and controlling areas where there might be the
presence of flammable, toxic gases and oxygen.

Description

The CE400 Central System, designed in a wall mount cabinet 285x230x130mm, is
composed by a front unit for the data processing with keyboard, backlighted graphic display
164x92 pixel, and by a input/output card and power supply. Power supply is 230Vac-50Hz;
the sensors are 20Vcc powerd. The cabinet of the Central System is designed to accept a
12Vcc 7Ah battery to maintain the system powered on in absence of Main power supply.
The CE400 Central System is able to manage up to 4 inputs for 4÷20mA sensors (S1, S2,
S3 ed S4); an auxiliary input for N.O. contacts (AUX) and is able to pilot up to 5 relay output
(AL1, AL2, AL3, AL4 e AUX).
To the Central System can be connected an Expansion Card ES400 to add other 4 inputs
for 4÷20mA sensors (S5, S6, S7 ed S8) and other 4 output relays (AL5, AL6, AL7 e AL8).

• The CE400 Central Unit can be connected to:

- Three-wires linear 4÷20mA transmitters for flammable gases series TS292K (IP65) or
TS293K (Flameprrof) with 0÷20%LIE scale, or series TS293Px (Flameprrof) with
0÷100%LIE scale.

- Two-wires linear 4÷20mA transmittrers, with elettrochemical cell sensors for toxic
gases, series TS220E (IP65) or with with oxygen sensors TS220EO with 0÷25%O2
scale. However the inputs can be set up for any type of detector with a 4÷20 mA signal
functioning with a 20Vcc power supply.

- Devices having a Normally Open contact (sensors with a relay contact, smoke sensors,
Normally Open pushes, etc.) connectable to an auxiliary input (AUX) that activates the
output relay AUX (U9).

• The measurement range of the inputs is divided into the following indications:

FAULT- (<1 mA) - UNDERFLOW (from 1 to 3,5mA) - NORMal (from 3,5 to 21mA), or
PRE1, PRE2, ALLarm, (setup levels) - OVERFLOW (from 21 to 24mA) - FAULT+ (over

the 24mA).

• For each sensor three alarm levels and the fault are available and addressable to
whatever output.
Every output can be configured as follows:

- delay ON up to 250 seconds at the overcoming of the set alarm level.

- delay OFF up to 250 seconds when the input decreases below the set alarm level.

- It can have a time ON for the activation from 0 to 250 seconds, activating for the
selected time and then deactivating only after the selected time has been passed,
whatever the input value is (even if the input remain over the set elerm level).

- It can be memorized (if it has not been set any time ON), so that to stay active even if
the detector that gave the input returns under the alarm level.

- It can be setup with a positive logic (normally activated relay) or with negative logic
(relay in normal position).

• The internal Buzzer can be activated or deactivated in case an AL3 alarm or the AUX
input occur.

• The internal Buzzer emits a “Bip” when keys are pushed.

• Every detector can be Excluded without phisically disconnecting it from the system or

deleting it from the programm. In this case the current value read from the system about
that detector will be showed as well, with the “ “ symbol on the side of the detector
number, but there will be no activity (alarms and outputs) on that value.

• There is also the possibility (and we suggest to always use it) to protect the configuration
settings by a 4 digits “Code” (Password). To modify the Outputs Configuration, Inputs
Configuration, Code or Battery, you will always need to insert the right password.

Central System Monitoring

Switching on the Central System, the display will show the following
message for a periond of 30 seconds. This is for stabilize the sensors
and to avoid false alarms. The remaining time is showed by a
contdown.

Than the Central System will show the situation of the connected
detectors. The Display shows all detectors (max 8).

Pay Attention – important Note: detectors inputs are protected against
accidental wire breakings (connection between detectors and Central
System) and against short circuits. If a short circuit occurs, to avoid

damages to the central system or to the sensor, the power supply to that
input is automatically stopped (all others continue to work properly). Simultaneously the yellow LED
“FAULT” lights up and the correspondant relay is activated (if programmed). Only after having solved the
short circuit problem (to test if the channel is no more in short circuit protection you need to mesure if there
is voltage between the terminals “+” and “-“ with a multimeter) it will be possible to restore normal
operational conditions.

Alarms Reset

From the main menu, press

ENTER

to enter into the Select menu.

Select Reset (the cursor should already be in that position) and press

ENTER

to confirm.

The following message appears: Reset done, than it will automatically
appear the Setup Menu.

Press

ESC

to go back to the main menu.

This procedure has to be done to reset the stored relay outputs when
the cause of the alarm has finished.

Sensor Details Viewing

From the main menu press

ENTER

to enter into the Select menu.

With the

key select Details and press again

ENTER

,

All settings details about Sensor 1 will appear.
In the 1st line you see the actual sensor status, in the 2nd and 3rd lines
you see the set scale, than you se the values of the alarm levels (L1,
L2, L3), the number of the relay linked to the alarm levels (OUT1,
OUT2, OUT3) and the sensor value in mA.
With down and up keys it is possible to view details of the

other sensors. (If a sensor is not used , it will appear Not Config.).
Press

ESC

to go back to the Setup menu.

Enaling – Disabling Sensors

It is possibile to exclude a sensor without disconnecting it from the
Central System or without deleting it from the programm. In this case
the voltage value read by the central system about that sensor will be
displayed with the symbol on the side of the sensor number but it
will have no effect on the alarms and on the central system outputs.

With the key … select Enable o Disable.
enter the number of the sensor you want to disable
(or to enable).

Pressing the key

ENTER

the following message will

appear for about 2 seconds:
