Symptoms
Action to be carried out
Expected results
1
Product is off, no
LED is lit
Check for a voltage of 176 to 288 VAC on the supply terminals:
- Terminals 1-7 correspond to SOURCE I
- Terminals 1-7 correspond to SOURCE II
The "AUT" LED is lit (if the cover is
closed)
2
The "Priority
SOURCE
Availability" LED
does not come on
Check the following parameters:
• the type of network => 3P (DIP Switch 1 on position A)
1P (DIP Switch 1 on position B)
• frequency
=> 50 Hz (DIP Switch 2 on position C)
60 Hz (DIP Switch 2 on position D)
• the nominal voltage => with a multimeter, measure the voltage across the terminals and report the value on the
potentiometer
The "Priority SOURCE Availability"
LED is lit
Check the thresholds and hysteresis of rated voltages (∆U) and frequencies (∆F) and report them on the
corresponding potentiometer
If using an Auto transformer - proceed as follows upon 1st switching on
• Step 1: HIC4xxA must be connected to a three-phase + neutral network (4NBL) for setting the neutral position.
Neutral position is detected upon first switching on
• Step 2: Connect the autotransformers. Warning: Neutral must be connected on the same side as in step 1
How to reset the neutral position:
• Step 1: Open the cover
• Step 2: Set DIP Switch 1 from 3P to 1P
• Step 3: Set DIP Switch 1 from 1P to 3P
• Step 4: Close the cover
3
The "Emergency
SOURCE
Availability" LED
does not come on
Check the following parameters:
• the type of network => 3P (DIP Switch 1 on position A)
1P (DIP Switch 1 on position B)
• frequency
=> 50 Hz (DIP Switch 2 on position C)
60 Hz (DIP Switch 2 on position D)
• the nominal voltage => with a multimeter, measure the voltage across the terminals and report the value on the
potentiometer
The "Emergency SOURCE
Availability" LED is lit
CAUTION:
a generator operating off load can generate a Fr and a U lower than the nominal values:
Check the thresholds and hysteresis of rated voltages (∆U) and frequencies (∆F) and report them on the
corresponding potentiometer.
If using an Auto transformer - proceed as follows upon 1st switching on
• Step 1: HIC4xxA must be connected to a three-phase + neutral network (4NBL) for setting the neutral position.

•
Step 2: Connect the autotransformers. Warning: Neutral must be connected on the same side as in step 1
How to reset the neutral position:
• Step 1: Open the cover
• Step 2: Set DIP Switch 1 from 3P to 1P
• Step 3: Set DIP Switch 1 from 1P to 3P
• Step 4: Close the cover

The product
remains switched
off after the
Priority SOURCE
is lost
Check if voltage is between 176 to 288 VAC across the power supply terminals of emergency SOURCE:
- Terminals 1-7 correspond to the Emergency Source
The "AUT" LED is lit
In case of transformer/ Genset, check that FT timer (Main Failure Timer) has finished counting down.
• Use a stopwatch.
• Start the stopwatch when the product has lost its Priority SOURCE.
- Contact 73 - 74 must be closed after 60 s max (M-G application)
- GENSET run command = contact 73-74 closed
- GENSET stop command = contact 73-74 open
The Genset works and the LED
"Emergency Source Disponibility"
is lit
5
The product does
not switch over
after the Priority
SOURCE is lost
Check that the product is not in manual mode:
• Automatic mode = cover closed
• Manual mode = cover open
The "AUT" LED is lit
Check that automatic operation has not been inhibited by an external order (terminals 207-210).
Check the status of led « Emergency SOURCE availability ». If it is off, refer to the symptom concerned (higher in the
list)
The "AUT" and "Emergency
SOURCE Availability" LEDs are lit
In case of Transformer / Transformer, check the setting of FT timer (Main Failure Timer). The duration of this time
delay is between 0 and 60 s. If necessary, use a stopwatch to check switching to SOURCE after FT countdown
At the end of the time delay, the
product switches to mechanical
position 0, and to emergency
SOURCE
6
The product does
not switch over
when the Priority
SOURCE is
restored
Check that the product is not in manual mode:
• Automatic mode = cover closed
• Manual mode = cover open
The "AUT" LED is lit
Check that automatic operation has not been inhibited by an external order (terminals 207-210).
Check the state of the "Priority Source Availability" LED. If it is off, refer to the symptom concerned (higher in the list)
The "AUT" and "Emergency
SOURCE Availability" LEDs are lit
Check the setting of RT timer (Main Return Timer). The duration of this delay is between 0 and 30 min. Use a
stopwatch to check the switch to Priority SOURCE after the RT timer
At the end of the time delay, the
product switches to mechanical
position 0, and to priority SOURCE
Check that the "manual retransfer" function is not active*
• Retransfer mode activated = contact 207-208 closed
• Retransfer mode desactivated = contact 207-208 open
* if this function is not required
Contact 207-208 must be open to
enable switching to priority SOURCE
7
Return to Priority
SOURCE
has been
executed, but
the Emergency
Source (for
a Generator)
continues to
operate
Check CDT timer (Cool Down Timer) has finished counting down - Fixed time delay: 4 min
• Use a stopwatch.
- Start the stopwatch when the product has switched over to the Priority SOURCE.
- Contact 73-74 must be open after time delay CDT has finished counting down
The GenSet switches off and led "
Emergency SOURCE availability"
is OFF”
Check that the product is not in automatic mode:
• Automatic mode = cover closed
• Manual mode = cover open
The "AUT" LED is lit
Check that automatic operation has not been inhibited by an external order (terminals 207-210).
