2. GENERAL
There are two general parameters such as “Module
Alive Beacon” and “Manual Button Function”.
These two functions play an important role in the
system control safety.
Enabling the alive beacon parameter it is possible
to know whether the device is working correctly.
Via the object “General” the value true is sent with
a preconfigured period. The receipt of this telegram
periodically means that the device is working
properly.
The manual control can be also enabled in this
section. The combo outputs can be controlled
through the push buttons on the device when this
option is enabled. (See the Appendix A: Manual
Control)

3. LOGIC GATE
Up to 4 logic gates can be used with the combo
device. In addition, each logic gate allows the use
of up to 4 inputs.
The standard logic operations AND, OR and XOR
are available. (See the Appendix B: Logic Gates)
FEEBACK OPTIONS
The status of the output can be shown normally or
inverted. This configuration can be done via the
parameter “Output Behaviour” and when it is
parameterized as inverted, the status of the output
is shown inversely.
Through the parameter “Send Feedback On”, the
type of feedback can be defined. The combo
actuator allows sending the result of logic gates
when the logic output is changed or conversely
when one of the logic inputs is modified.
Additionally, it is possible to define a cyclic sending
of the feedback which permits getting information
about the output status periodically.
SWITCH DELAYS
The logic output can operate with delays previously
configured.
The logic output takes the values ON and OFF with
delays. Depending of the switch delay parameters
configuration, it is possible to set an ON delay
(TON), an OFF delay (TOFF) or both at the same
time.

5. FUNCTIONS
5.1. LIGHTING
The total number of device channels can be used
for direct connection of lighting circuits.
The lighting configuration allows a large number of
configurations which are described below.
TIME DELAYS
The function “Time Delay” allows the output to
operate with a delay previously configured.
Different actions can be executed using this
function:
- Staircase Function:
After switching on the light, it will remain ON for a
configurable time (TSF). After this time, the output
switches off automatically. Each time an ON
telegram is received while the lights are ON, the
delay time is restarts as long as the “Off Delay
Retriggerable” parameter is enabled.
Fig2. Staircase Function
Fig3. Staircase Function Retriggerable
- ON/OFF Delays
The output is switched ON and OFF with delays.
Depending of the “Time Delay” parameter
configuration, it is possible to set an ON delay
(TON), an OFF delay (TOFF) or both at the same
time. As well as the staircase function, the delays
can be retriggerabled.
Fig4. ON/OFF Delays
Fig5. ON/OFF Delays Retriggerable
WORKING HOURS COUNTER

Combo Output Module
Product Manual
©2017 INTERRA 18 PM131126001A
This function allows counting the hours that the
lighting channel remains On or Off. This selection
can be done through the parameter “Working
Hours Counter”.
The current value of the counter can be transmitted
periodically via the object "Hours Counter".
Depending on the “Count Direction” configuration
the value of this object increases or decreases.
With an incremental counter, the counter starts
from the value 0 and it is incremented. On the other
hand, with a decremental counter, it is necessary
to send an initial value via the object "Hours
Counter" to be decremented. If this value is not
sent, the counter will remain 0 and it will be useless.
Additionally a “set point for alert” can be configured.
The object “Counter Set Point Reached” takes the
value 1 when the counter reaches the value
configured in this parameter.
With a decremental counter, the value
“set point for alert” should be 1 or a low
value.
Knowing the life of the lamps connected to the
outputs, the parameters can be configured to have
a preventive maintenance.
The following figure shows an example of
incremental hours counter when the output is ON:
Fig6. Hours Counter
This function permits resetting the value of the
counter via the object “Reset Counter”.
This functionality is not available for
ITR520 and ITR524.
FLASHING
Via the “Flashing” communication object, the
output starts to flash as soon as the value ON is
received. The period (TFI) is previously configured
in the “Flashing Interval” parameter.
When the flashing function is switched off, the
output retrieves the value prior to flashing
activation.
The contact life of the contacts should be
considered and can be found in the
technical data.
Fig7. Flashing
LOCKING
This function allows the lights to be locked to a
value. During a locking, the output is blocked and it
can no longer be controlled via any telegram.
It is possible to define the light status during the
locking and the value that the lights take after the
locking. When the parameter “Output Status at End
of Locking” is set to “No Reaction/Last State”, it
must take into account that the output after the
locking will take the last value received through the
bus even though this value has been received
during the locking time. Via the object “Locking” the
locking function can be enabled or disabled.
The locking function remains active
even after bus voltage failure.
The manual control via the push buttons
of the device is possible during the
locking.
SCENES
Up to 16 scenes can be configured for each lighting
output. The configuration of each scene permits:
- Assign a number of scenes (1-64).
- Set a value for the output.
- Enable storing of the scene.
- Define an ON Delay for the scene.
Via the object “scene”, telegrams which contents
the call or store functions of a scene are sent.

Combo Output Module
Product Manual
©2017 INTERRA 19 PM131126001A
Up to 64 different scenes are managed via a single
group address and the scene number telegram
must match with the scene number previously
configured in the combo parameters. The scene
number (1-64), is used to recall the scene via the
corresponding object. For storage the scene, the
value sent via the object “scene” must be
128+scene number.
When a scene is configured with a
number, the value to send for calling
that scene must be that number -1. For
example, if a scene is configured with
the number 24, the number to be sent
via the object “scene” must be 23. On
the other hand, the value 152 (128+23)
must be sent for storage the scene
number 24.
The recall of each scene can be delayed whether a
time delay has been defined previously in the
parameter window. This option allows creating
dynamical scene sequences when several outputs
are combined with different delays.
After ETS programming, the scene
values parameterized for the output
concerned will be overwritten into the
actuator. It means that any change made
by the user will be deleted. Therefore it
is important, before any maintenance, to
know the previous scene configuration
and whether the user wants to keep
operating with that configuration.
LOGIC FUNCTION
With the logic function a new communication object
is added (Logic Input) which is logically linked with
the object “On/Off”. The value of these two objects
is evaluated and then the output will be switched
on or off depending on the result of the logic.
The combo parameters allow defining the status of
the logic input after a bus failure and the ETS
programming.
The logic object will take the values
defined in these parameters but the
reaction of the output after bus failure
will be as it is defined in the parameter
“Behaviour After Bus Voltage Return”.
After the first action, the logic value is
taken into consideration.

FEEDBACK FEATURE
The status of the output can be shown via the
object “Status”. Additionally the value of the
feedback telegram can be inverted.
When the feedback telegram is enabled, the status
information is transmitted every time that a change
occurs on the output. However, it is also possible
to define a periodical sending of the status through
the parameter “Feedback Periodical Sending”.
Thereby, the current value of the output is
transmitted with the period configured.
Additionally, to reduce the bus traffic after any
failure, a delayfor the status feedback transmission
at startup can be parameterized. When this option
is used, the status of the output after a bus voltage
failure is sent once the time delay configured has
elapsed.
The delay configured only affects the
sending of the feedback. The behaviour of
the outputs has no effect and they can
even be switched during the course of the
delay.
BUS VOLTAGE FAILURE
The behaviour of the output during and after bus
voltage failure can be parameterized. The combo
is equipped with bistable relays. That is why the
reaction of the output during bus voltage failure can
be configured too.
The combo actuator allows three different
behaviours for bus voltage failure:
No Reaction/Last State: The relay of the output has
no reaction and remains the last state received.
ON: The relay is closed.
OFF: The relay is opened.
