SYMPTOMS ACTIONS TO BE CARRIED OUT EXPECTED RESULTS
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 :
• 127 / 230 Vac model: - Terminals 3-5 corresponding to the Emergency
Source
• 230 / 400 Vac model: - Terminals 1-7 corresponding 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 60s max (M-G application )
- GENSET run command = Contact 73-74 Closed
- GENSET stop = Contact 73-74 Open
The Genset works and the
LED «Emergency Source
Disponibility» is lit
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 external control
commands (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 tansformer / Transformer, check the setting of FT timer (Main Failure
Timer). The duration of this time delay is between 0 and 60s. 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.
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 external control
commands (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
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 external control
commands (terminals 207-210)
ON LOAD TESTS
cannot be launched
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 external control
commands (terminals 207-210)
Check if the ON Load test has started:
• On Load Test activated = Contact 207-209 Closed
• On Load Test inhibited = Contact 207-209 Open
The ON LOAD TEST starts.
