INIM Flex5/DAC User manual

Flex5/DAC
Alternating current output expansion
The Flex5/DAC provides 5 terminals for controlling both AC and DC loads.
Each terminal can be configured as an output with the following attribute type:
• Relay, dry contact for AC or DC devices of up to 10A
• TRIAC ON/OFF, electronic contact that functions as a relay for AC devices up to 3.5A
maximum
• TRIAC dimmer, dimmer contact for power-choke type AC devices of up to 3.5A
Each terminal has a sensor that measures the current (both AC and DC) absorbed by
the load and ensures that the terminal is galvanically isolated from the rest of the
board.
From the measurements performed on the board and for each of the terminals, the usable
electrical parameters are provided both on the Flex5/DAC display (by navigating with the
right/left keys) and on the Alien user interface (through the “Commands” section) and via
management software for INIM systems:
• Supplied voltage to external load
• Power absorption from external load
The electrical power value is calculated using the measure of the current drawn and
the values of the set or effective voltage, as in the case of the connection with the
primary power-supply network.
• Phase displacement or power factor (PF), measured exclusively for AC loads with
non-dimmable mains voltage and only when phase and neutral are connected to
expansion through terminals 15 and 16
• Percentage of the supplied power with respect to the maximum possible, measured
exclusively for dimmable loads.
• Consumption, in KWh
The consumption can be viewed only on the FLEX5/DAC display and is supplied as a
total (“KWh TOT”), as partial (“KWh Pr1” and “KWh Pr2”, two partials resettable from
the menu) for each terminal and for all devices (“BOARD TOT”).
For a detailed description of the functionality and configuration of a FLEX5/DAC in a
INIM intrusion control system please refer to the installation manual of the control
panel.

Manuale di installazione
Installation 3
2Installation
The Flex5/DAC is suitable for DIN Rail mounting.
It must be installed inside a fireproof enclosure with UL 94-5V flamability rating.
TAMPER
PROTECTION
It should be protected by a normally open microswitch (not included) which must be
applied to the enclosure in which the FLEX5/DAC is installed.
The microswitch should be connected to the appropriate connector (tabella 2, G).
3Connecting OUTx outputs
Each of the 5 OUTx terminals on the Flex5/DAC expansion board can be used for
connections with both AC and DC powered devices.
ATTENTION! Dangerous outputs.
The outputs can be used to drive only 5 hazardous voltage devices or 5 safe voltage
(SELV) devices.
In normal operating conditions of a SELV circuit the voltage between any two of its
conductors or between any of the conductors and the ground must not exceed 42.4V peak
or 60V DC. When these values are exceeded, the voltage is to be considered hazardous.
Use of promiscuous mode for devices (hazardous and safe voltage) is possible if one
output is relinquished. This output will act as a separator between two diversely driven
terminals, as illustrated in the following configuration example:
If the outputs are used on mains (hazardous) voltage, in addition to the above
requirements, it is necessary to take the following compulsory measures:
• to connect in series an appropriate protection fuse to the selected output
• to use through phase only or through neutral only for all the terminals
4Snubber protection
The snubber protection circuit applied to OUT terminals can be bypassed without
affecting normal functioning of the outputs.
However, it is advisable to bypass the snubber circuit for:
• relay outputs connected to lighting devices
• outputs configured as Triac ON/OFF
•dimmableoutputs
ATTENTION! Do not bypass the snubber protection circuit in applications which provide for the use
of motors.
Snubber bypass operations:
ATTENTION! When carrying out the following operations ensure that the mains power supply is
disconnected from the system.
1. Open the cover of the Flex5/DAC by releasing the backlocking grips (tabella 2,
H).
2. Find the jumper relating to the OUT output concerned.
3. Remove the jumper.
4. Close the cover, reset and restart the system.

4Connection to the Mains power source
FLEX5/DAC
5Connection to the Mains
power source
The connection of terminal AC~ to the primary power source (phase and neutral) is
necessary in order to:
• Use an output for control of dimmable devices
• Measure of actual power consumption
• Measure of phase displacement or power factor (PF)
For a correct functioning of these features the loads must be connected to the same
mains line connected to the AC~ terminal.
The mains line must be protected by a safety-standards compliant circuit breaker (trip
switch).
The circuit breaker (trip switch) must be located externally to the apparatus and should
be easily accessible. The distance between contacts must be at least 3mm.
The manufacturer strongly advises the use of a magnetothermic switch with C
intervention curve and nominal (maximum) current - 16A.
The protective earthing system must be compliant with all safety standards and laws in
force.
ATTENTION! Be careful during the mains connection phase.
Danger of electric shock.
The screw terminals of the AC~ input are galvanically isolated from the rest of the
expansion.
Such an input is not used to power the expansion or downstream devices but for the
measurement of the electrical network parameters.
Whichever AC~ input terminal is used for the phase or neutral conductor is irrelevant.

Connection to shutter motors 5
6Connection to shutter motors
Flex5/DAC can drive shutter motors
(asynchronous monophase bidirectional
motors) by means of 2 OUT terminals.
In addition to this, you have to follow these
necessary conditions:
• the 2 outputs must be configured as relay
• the interlock function must be enabled on
the pair of terminals
• the 2 outputs must have the snubber circuit
protection jumper inserted
• the connection of terminal AC~ to the
primary power source (phase and neutral)
is necessary
7Programming
Flex5/DAC expansion board provides a menu for the programming of its parameter
settings and viewing of the data corresponding to each of its 5 OUTx terminals.
This menu can be accessed by means of the buttons and display located on the front of
the DIN enclosure.
Press the OK key to view the list of options available on the menu, the Canc key will
allow you to exit the section you are working on without saving any changes made. The
values can be changed using the “+” and “-” keys.
Options available on the menu:
•Set address, sezione per impostare l'indirizzo della periferica sul I-BUS.
•Output options, list of selectable outputs for parameter changes:
•• Restore output, forces reset in situations of output malfunction.
This procedure must be carried out after verifying that the cause of malfunction
has been eliminated.
•• Set voltage, for the value setting (in Volts) of the voltage supplied to the
output
•• Clear KWh Pr1
•• Clear KWh Pr2, allows reset of the meter for partial consumption in KWh of
the individual terminal
•System options:
•• Clear KWh Pr1
•• Clear KWh Pr2, allows reset of the meter for overall consumption in KWh of
the FLEX5/DAC
•Set backlight allows adjustments to the display backlight.
•Hard reset, following a request for command confirmation, the FLEX5/DAC will
restore the factory default settings.
This operation will not clear the terminal consumption meters, neither individual nor
total.
