As the channel is turned on, the output drifts from 0 to the programmed value (V0SET or
V1SET according to the VSEL signal level) at the programmed rate (RAMP-UP
parameter).
It can be programmed either via Local or Remote Control.
Setting the POWER parameter to ON automatically resets the alarm conditions.
Moreover, it sets the TRIP counter again to its initial programmed value, so that the
TRIP counter will start again from the programmed TRIP value as soon as another Over
Current condition occurs. Refer to § 4.4.13, p.31 for further details on the TRIP counter.
4.4.15
POWER-ON
(POn)
This parameter controls the behaviour of the channel at Power-On or after a Restart.
It can be set as:
•
Enabled (EN),
•
Disabled (DIS).
If it is enabled, at Power-On or after a Restart each channel is restored in the same
condition (defined by the POWER parameter) it was before the Power-Off or Reset.
If this option is disabled, at Power-On or after a Restart all the channels are Off,
independently from the condition in which they were before the Power-Off or Reset.
It can be programmed either via Local or Remote Control.
4.4.16
POWER-DOWN
(PDwn)
This parameter affects the way the channels react at a Power-Off command caused by a
TRIP condition.
It can be set as:
•
KILL,
•
RAMP.
If the KILL option is selected, the relevant channel will be switched off immediately.
If the RAMP option is selected, the voltage will drop to zero at a rate determined by the
value of the Ramp-Down parameter programmed for that channel.
It can be programmed either via Local or Remote Control.

Channel status
Several messages on the status of each channel are displayed by the User Software
Interface and particularly in the
Channels Window
. For a list of these messages please
refer to § 7.1.9, p.49.
