5 Control and Programming
How to verify the trip current set
Press the set button for more than 2 sec. until LED channel 1 starts to blink Orange.
• The number of Orange blinks indicates 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 starts to blink
Orange.
• The number of Orange blinks indicates 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.
1. At this time it is possible to count the number of orange blinks
according to the number of Ampere set for the trip current: 1 Blink =
1A ... 10 Blinks = 10A
2. Press the push button for a number of times equal to the desired
number of tripping Ampere.
3. Verify option: after selecting the desired Ampere, the device will return
the set number after 2 sec
4. 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 restarts from 1A.
5. To confirm the New Trip Current setting, press the push button for 2
sec. until LED channel 2 starts flashing orange.
6. Set the current limit for channel 2 in the same way as for channel 1.
7. 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 within 20 seconds, the procedure automatically
ends and the LEDs resume flashing regularly. The device retains the old
values.
• Note: at first power up the device is programmed at 3A for each channel.
