POWER SUPPLY TL 135
Installation Manual
FUNCTIONS
The power supply is made of: one linear power supply, with serial voltage regulator, limited in constant precision current (rectangular
limitation); one analogical control circuit and one microcontroller supervision circuit.
Supplying is shared out among four outputs, on terminals protected by corresponding fuses:
BAT: where the back-up battery will be connected OUT1, OUT2 and OUT3: for general charges
The charge of the battery occurs at constant voltage (13,8 Vdc @ 25°C) with limited current.
Leds in the control board (see Pict. 1) show:
Cut fuse for any of the outputs, with Led off (DL9, DL10, DL11)
Current consumption by the charge (2 green and 1 red, DL5, DL6, DL7)
Mains presence (DL1 RETE)
Failures (DL2)
Control of battery efficiency.
The power supply periodically controls the batteries efficiency:
-At first power supply activation, the microprocessor carries out the test of battery presence after 30 seconds. If battery is
connected, the test will be carried out periodically every 10 minutes whilst, if not connected, it will continue carrying out the
test every 20 seconds, showing the anomaly with DL2. This anomaly will be kept in memory until a battery is connected.
-During standard operating, the battery efficiency is checked watching batteries voltage. If batteries do not manage to
maintain an acceptable voltage during test, there will be activation of DL2.
-In case of missing mains, if the battery voltage is lower than 9,5Vdc, the battery and the charge are disconnected in order
to avoid malfunctioning of the system and to avoid deep discharge of the battery. The battery will be reconnected in case it
is replaced or in case of mains restore.
-During standard operating, a test of the battery internal resistance is carried out every 90 minutes; if the internal resistance
happens to be over 1 ohm, there will be on of DL2. It will then be necessary to replace the battery and check that terminals
and fuses have a good electrical contact. When the battery is replaced, having mains presence, the test of the internal
resistance is repeated within 5 minutes.
In order to avoid a possible failure damaging the charges or the battery, a protection circuit against over-voltages has been inserted,
made by a SCR and a fuse. There also is a fuse for alternated mains supplying. In case of failure in the power supply or of mains
absence, the battery will supply the electronic circuits.

Security instructions
- For AC supplying, provide a 6 A protection bi-pole magneto-dynamic switch, easy to access.
- The wires must have a section of 1,5 mm and be equipped with adequate buttonholes where they are subject to
pressure contact.
- The installation of the power supply must be carried out by qualified personnel aware of the security standards EN60950
and concerning power supplies CEI-64-8.
INSTALLATION
Electrical connections
Connect the power supply to the mains 230 Vac by use of bi-pole 6 A magneto-thermic switch (minimum distance between contacts
3 mm) aimed to protect the line from possible short-circuits and to protect the operator from current losses towards ground.
IMPORTANT:
use different cable-passes and pipes for ac supplying input (mains 230 Vac) and dc outputs + alarms (SELV).
The minimum section recommended for ground connection is 1,5 mm.
For connections refer to figures Pict.1. In these pictures the following important steps are shown:

Controls and Adjustments
The parameters shown below (P1 and P2) are adjusted at factory and must in no way be altered by the operator.
Tampering of these parameters automatically means the lost of the warranty.
P1 Potentiometer for adjustment of the output voltage -- P2 Potentiometer for adjustment of the output current limit.
Start of the system
Even if not imperative, the following sequence of connection is suggested:
1. Connect mains and ground to the concerned terminal J1. The charge Led flashes and after about 30 seconds the missing
battery Led flashes
2. Connect the battery. After 20 seconds the Led switches off
3. Connect the charges: the Leds indicating the current supplied light up
Servicing
Periodical programmed servicing must be carried out by qualified personnel in order to prevent the possibility of a malfunctioning of
the power supply. It is recommended to carry out servicing every 6 months and to evaluate control panel of the system in order to
check possible alarms during tests.
- Check the connections of the 230 Vac supplying lines
- Check the connections of the alarm indication lines and related shields
- Check the battery connections, they have to be well tightened and there must be no oxidation
- Check the output voltage on the charge (see electrical specifications)
- Disconnect the battery and check if the voltage of the power supply is within the values shown.
- After re-connecting the battery, disconnect the primary supplying and check if the battery can maintain the voltage on the higher
12Vdc charge. On the contrary, replace battery immediately.
