SYMPTOMS ACTIONS TO BE CARRIED OUT EXPECTED RESULTS
Adjustment
potentiometers of
the rated voltage
and frequency and
voltage thresholds
Check for a voltage of 176 to 288 Vac on the supply terminals:
• 127 / 230 Vac model :
- Terminals 3-5 correspond to SOURCE 1
- Terminals 3-5 correspond to SOURCE 2
• 230 / 400 Vac model :
- Terminals 1-7 correspond to SOURCE 1
- Terminals 1-7 correspond to SOURCE 2
The "AUT" LED is lit (if the
cover is closed)
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 accross 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: ATyS M6s 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
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 accross 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.

• Step 2: Connect the autotransformers. Warning: Neutral must be
connected on the side defined 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
