Operational assistance
Before performing any operation on the speed controller, switch off the power circuits and
check that the capacitors are discharged (about 1 mn after switching off).
ATTENTION
The d.c. voltage at the terminals marked +/PA and -/PB and the terminals J9 + and J8, can
reach 385 Volts for the ATV-16 ...M2 when under load and 790 Volts for the ATV-16 ... N4.
If there is a problem at set-up or during operation, check first of all that the
recommendations concerning environment, mounting and connection have been followed.
The Altivar 16 does not require preventive maintenance, but we recommend regular :
. checks of the state and tightness of connections.
. checks that the temperature around the unit remains at an acceptable level.
. removal of dust from the speed controller if necessary.

Monitoring faults :
The first fault detected is monitored as long as the supply voltage is maintained.
The fault relay is tripped.
Clearing memorized faults :
. Switch off the power supply to the speed controller.
. Find the cause of the fault before resetting.
. Reconnect the power supply, which will erase the recorded fault if it has disappeared.
Note : the VW3-A16101 and VW3-A16102 display / adjustment options enable fault codes
to be displayed.
