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:

IST-1400.AA01.02 CE400 “CITY” / User Instructions PAG. 4/21

TECNOCONTROL S.r.l. - Via Miglioli, 97 20090 SEGRATE (MI) - Tel. +39.02.26 92 28 90 - Fax +39.02.21 33 734

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.

IMPORTANT REMARK

INSTRUCTIONS CONTAINED IN THE MANUAL BELOW INCLUDE INSTALLATION AND

SYSTEM SETUP PROCEDURES TO BE EXECUTED ONLY BY QUALIFIED AND

AUTHORIZED PEOPLE.

CE400 INSTALLATION

The CE400 is a wall mount central system, it has to be fixed with 3 little blocks in the wall through the

3 holes of the metallic base of the case. We suggest you to mark and fix the central hole first, then

you can mark the other two holes keeping the central system horizontal.

To open the cover of the central system, unscrew the 4 frontal screws. Pay attention in opening the

cover because it is connected with a flat wire to the electronic board fixed on the back side. To easier

install it on the wall, disconnect the flat wire, disconnecting it from the connector. (See Fig.2).

Opening the two tongues on their external side the connector slip automatically out.

To connect it again it is necessary to slip it into the polarized connector to avoid any possibile error,

and push it till when the two tongues will close. Then fix the cover again srewing the 4 screws down.

Electrical connections

All electrical connections have to be made in the metallic base of the central system.

Mains Power Supply “230Vac” has to be connected on the power supply terminal “L, N and Ground”

(Fig.4).

The 12V 7Ah Battery (if present) has to be connected to cables “B+” (Red) and “B-” (Black) (Fig.4).

On the cisrcuit placed in the metallic base you can find all terminals for the inputs and outputs

connection. Terminals (Fig.3) have a polarized clutch (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.

Connection diagrams showed in Fig.5 e 6, to simplify, are always indicated with all sensors.

Inputs: keep into consideration that the Central System CE400 disposes of 4 inputs 4÷20mA only

(from S1 to S4) and 1 input for Normally Open contacts (AUX). To get other 4 inputs (from S5 to S8),

it is necessary to add the Expansion Card ES400 (On the right of the drawing). Inputs “S1, S2….etc.”

accept any 4-20mA linear current signal, coming from 2-wires or 3-wires transmitters. (See chapter

Sensors Connections). “AUX” input accepts only Normally Open contacts, free from voltage.

Output: The Central System CE400 disposes of all exchange contacts relay outputs free from

voltage. Contacts current carrying capacity is 3A at 250Vac. The Central System CE400 has 5 exits

(AUX and from AL1 to AL4), Expansion Card ES400 has other 4 exits (from AL5 to AL8).

Each relay output contacts are indicated with “C” (common), “NC” (normally closed) and “NA”

(normally open). This indication is referred to relays in “not powered” position, this means normally

deactivated = Negative Logic.

Sensors Connection

Connection of 2-wires 4÷20mA transmitters

Connection of 2-wires 4÷20mA transmitters has to be made (Fig.5) between the “+” and “-” terminals

of the transmitter and the correspondant “+” and “S” terminals of the Central System inputs card.

The section of the connection cables between

sensors and central system has to be calculated in

function of the distance as indicated in the table.

Transmitters series TS210E and TS220E need a

shielded cable. The braiding has to be connected to

the "-" of the input sensor terminal.

Connection of 3-wires 4÷20mA transmitters

Connection of 3-wires 4÷20mA transmitters has to be made (Fig.6) to the “+”, “-” and “S” Terminals of

the transmitter and the correspondant terminals of the Central System inputs card.

The section of the connection cables between

sensors and central system has to be calculated in

function of the distance and the used sensor, as

indicated in the table. Sensors series TS292K,

TS293K and TS293P don’t need shielded cables.

Transmitters Use

PAY ATTENTION: Transmitters calibration is made with calibrated gases, sealed trimmers can be

regulated only by authorized and trained people or by our technicians using calibrated gases.

See the specific Users Instructions of the Treansmitters.

Please note that transmitters series TS292K, TS293K and TS293P for flammable gases, need a

warm-up time, in clean air, for about 20 seconds. After this time they are able to detect gases, but

they reach optimal stability after about 3 hours of continuous work, tests with sample gas should be

done after this time.

Transmitters series TS210E and TS220E reach the optimal stability conditions, in clean air, after

about 1-2 hours of continuous work.

Auxiliary Input and Output AUX

Connection with Normally Open contact devices

Connection to devices (Relay contact detectors, Smoke detectors, Normally Open buttons etc)

disposing of a “not powered” and Normally Open contact, is made (Fig.5) to “S” e “-” terminals of the

AUX input on the Central System.

Auxiliary Power Supply Exit

To the AUX terminal (between “-“ and “+”) it is also available an auxiliary output, about 12Vdc

(11÷16Vcc), for a maximum charge of 12W. Pay attention: we suggest to protect this power supply

with a fuse if the connected device doesn’t have one.

Delay ON: it is the delay time (max 250 seconds) of the output

activation from the moment when the gas concentration overpass the

alarm setting.

Delay OFF: it is the delay time (max 250 seconds) of the output

deactivation from the moment when the gas concentration returns

under the alarm setting.

Time ON: it is the time lenght (max 250 seconds) durino which

the output stay active from the moment when the gas

concentration overpasses the alarm setting. When this time has

elapsed, the output returns to its original status even if the gas

concentration is over the alarm setting

Positive Logic: it indicates if the relay works

normally activated (Positive Logic) or normally

deactivated (Negative Logic). The selection is made selecting

“NO” (Negative) or “YES” (Positive) with key.

Latched Output: it indicates if you want to keep the output

active even if the gas concentration returns under the alarm

setting. Select “NO” or “YES” pressing the key. The

output will need to be manually deactivated by the operator.

Pay attention: this paramenter don’t has to be used if you

have setup a Time ON before, this because there will be a

conflict between the defined output activation time and the

“infinite” time represented by the latched output.
