The CE100 central unit has 3 Alarm relays:
Each sensor has 3 alarm levels associated to the Alarm Relays (PRE1, PRE2 and ALL). Consider that
the three relays are in common with all sensors, but it can be set different alarm values for each
single sensor.
The CE100 central unit has a Fault relay (FAULT)
- In case of Fault the sensors activate the common Fault Relay. (FAULT).
Every output relay can be configurated as follow:
- Delay ON from 0 to 4 minutes at exceeding of the alarm threshold set.
- Delay OFF from 0 to 30 minutes to the return under the threshold level set.
- Time ON from 0 to 30 minutes, this function only works, if you want to stop the alarm output after
a defined time, even if the sensor remains above the alarm threshold set. (The program does not
allow setting it, if it’s already used the “Delay OFF”). For example it can be used to activate devices
that cannot be powered for a long time or to send an impulse to a telephone dialer or any other
device.
- MEMORY The relay stays in “Alarm” even if the sensor returns under its threshold level. (The
program does not allow to set it, if it’s already used the “Time ON”). Make the RESET to reset it to
the normal conditions.
-LOGIC the relay can be set in POSitive logic with normally closed contact (NC) or in NEGative
logic with normally opened contact (NO).
CE100 central unit has an internal BUZZER:
-It emits a “Beep”, when the keys are pressed, moreover, from the Menu “Divers” (Miscellaneous), it
can be chosen to let it active in case of Alarm (ALL)
CE100 central unit has got a function that allow to disabilities sensors:
-Each sensor can be “disabled“without remove or cancel it from the program.
In this case, the sensor value will be visualized with *symbol before the sensor number, but it
cannot activate any relay. This function is useful in case of Faults, anomalies or maintenance and
sensor calibration.
Ce100 central unit is protected from “PASSWORD”
-The menu access is protected through “Code” (4 numbers Passwords). To enter to this function
it’s necessary to digit the Password.
CENTRAL SYSTEM MONITORING
When switching on the CE100, after the message shown
by side, the display will show a 60 seconds count down.
This is for stabilize the sensors and to avoid false alarms.
Then, the CE100 will show the situation of the connected
detectors. The Display shows all detectors (max 6).
(Detectors not programmed are indicated with a
dashed line). Upper on the right is indicated the
enabled code level. (See at page18 chapter
Password).
For each sensor, the display shows the measured value and also its status: FAULT< (<1mA)
PRE1, PRE2, ALL, FAULT> (over 24 mA). (See explaination in the chapter “Sensor details”).

Important Note:all detectors inputs are protected against 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.

CONNECTING THE DETECTORS
CENTRAL UNIT CE100 can be connected up two detectors with 4 to 20mA output (S1 and
S2). To have other four (from S3 to S6), you need to install the Expansion Modules CE101.
CE101 MODULE (Expansion of two inputs for detectors 4 to 20mA)
Inputs by installing a CE101 module can be connected two sensors (S3 and S4). Installing
a second CE101 module can be connected other two sensors (S5 and S6).
Connecting with CE100 the first module CE101 should be connected with 4 wires, to
CE100 terminals “+, –, S3 e S4“, as shown in figure 6. If you installed the second module
CE101, is should be connected to the CE100 terminals "+, -, S5 and S6".

CONNECTION OF THE SOLENOID GAS VALVE WITH POSITION SENSOR
If you have installed a Tecnocontrol solenoid valve with the position sensor (VR400 to VR480
models) connected to the "VALVE CONTACT", in the menu "MISCELLANEOUS" you must
configure YES the STATE EV (Electro Valve).
WARNING: This control works only on 3rd alarm level, so the valve must be connected to
relay ALL.
If an alarm occurs, the CE100 will check if the valve has been effectively closed, otherwise
the yellow LED will light and the FAULT relays activates. The display will show the symbol
for the failure to close.

NOTES: The AL101 and AL102 modules have an auxiliary output “VALVE“ at 12VDC/12W
max (terminals E+ and E-). You can power a gas solenoid valve or other device, operating at
12VDC (10.8÷13.8VDC), whose absorption maximum does not exceed 12W (1A). This
output is protected from "Short Circuit", but should not be connected loads that exceed the
indicated current capacity, or which may generate noise on power supply.

be out of calibration on the beginning of the scale.
PRE1 The 1st alarm threshold has been exceeded and the related
output relay is active (if configured).
PRE2 The 2nd alarm threshold has been exceeded and the related
output relay is active (if configured).
AL The 3rd alarm threshold has been exceeded and the related
output relay is active (if configured).
OVERFLOW The input signal is between 21 and 24 mA. The sensor is
detecting gas, but the full scale has been exceeded.
FAULT+ The input signal is greater than 24 mA. The sensor could be
faulty, or it’s detecting gas but it has exceeded its full scale.
Mains 230Vac power supply is missing.
Battery empty.
The valve with Position sensor is not close.
Display switched off if the greed Led is ON, the Display could be damaged or the
contrast is too low, tries to regulate it with the trimmer on the
