2 Safety and warning notes
WARNING –Explosion Hazard Do not disconnect
Equipment unless power has been switched off or the area
is known to be non-hazardous.
WARNING –Explosion Hazard. Substitution of components
may impair suitability for class I, Division 2.
WARNING –Switch off the system before connecting the module. Never
work on the machine when it is live. The device must be installed in
according to EN61010 or EN62368-1. The device must have a suitable
isolating facility outside the power supply unit, via which can be switched
to idle. Danger of fatal Injury!
WARNING –The device is equipped whit an internal fuse. If the internal
fuse blows Up (fails opens), it is most probable that there is a fault in the
device. If this failure occurs, the device must be returned to the factory.
3 How to Install
Mounting

4 Drive a Channel
Turn On Channel
On the first power up, all channel are OFF.
To enabling channel 1(LED Blink Red for short time) push the set button
for short time: one time; < 1 sec.
To enabling channel 2(LED Blink Red for short time) push the set button
for short time: two time; < 1 sec.
Each channel could be enabled after a Switch off for Overload or Short
circuit, (LED Red ON). When the LED Red flash for 3 time, the devise it’s
ready to turn ON the channel. If the channel is ON, the device maintains
in memory the state also without the power; this function it is not enabled
if the device is in configuration mode.
Turn Off Channel
When the channel 1 is ON (LED Blink Green or Orange for short time)
push button for short time: one time and the channel turn OFF; < 1 sec.
When the channel 2 is ON (LED Blink Green or Orange for short time)
push button for short time: Two time and the channel turn OFF; < 1 sec.
If the channel is OFF, the device maintains in memory the state also
without the power.
5 LED indication
•Led RED ON: the channel is in protection due to Overtemperature,
Overcurrent, Over/Under voltage (<8.5V or >32.5V).
The device could be in this situation for some sec.
In this condition it is not possible turn ON the device.
•Led RED flashes three times for short time: the channel is OFF after
switch protection, but is ready to be turned ON.
Push the set button to turn ON the device.
•Led RED flashes one for short time, the channel is OFF but ready
for turn ON. Push the set button to turn ON the device.
•Led GREEN blinks for short time: the channel is ON and the current
through the channel is <80% of the tipping point switch.
•Led ORANGE blinks for short time: the channel is ON and the
current through the channel is >80% of the tipping point switch.
•Config. Mode: One Led OFF and the second Led ORANGE blinks,
in this condition it is enabled the procedure:
•Verify the trip current set for each channel
•Configure the trip current for each channel

6 Control and Programming
How to verify the trip current sett
Press the set button for more than 2 sec. until LED channel 1 start to blink
Orange.
•The number of Orange blink provide the number of Ampere set for
the trip current: 1 Blink = 1A … 10 Blink 10A
•Press the push button for more than 2 sec. until LED channel 2 start
to blink Orange.
•The number of Orange blink provide the number of Ampere set for
the trip current: 1 Blink = 1A … 10 Blink 10A
•End the procedure by holding down the button for 2 seconds until
the LEDs resume their regular flashing.
If the button is not pressed for 20 seconds, the procedure ends
automatically and the LEDs resume their regular flashing.
How to set the trip Current
Press the push button for more than 2 sec. until LED channel 1 start to
blink Orange.
•Option: it is possible count the number of orange blinks according to
the number of Ampere set for the trip current: 1 Blink = 1A … 10
Blinks = 10A
•Press the push button for a number of time equivalent to the desired
number of tripping Ampere.
•Verify option: successively press the desired Ampere, the device will
return the set number after 2 sec
•Correction option: correction of the current setting by pressing one
more time the set button: e.g., 6A + 1A more = 7A. When 10A is
reached, the counter restart from 1A.
•To confirm the New Trip Current setting, press the push button for 2
sec. until LED channel 2 start flashing orange.
Set the current limit for channel 2 in the same way as for channel 1.
•Confirm the new Trip Current of the channel 2 and finish the
Configuration procedure by holding the button for 2 seconds until the
LEDs start flashing regularly again.
•Mandatory: to ensure the new value is set, the procedure must be
completed. If the button is not pressed for 20 seconds, the procedure
automatically ends and the LEDs resume flashing regularly. The
device retains the old value.
Note: On the first power up the device is programmed at 3A for each
channel.
