Description
Digital input/output DIO2 (as indicated by
delayed status, bit 1).
DIIL input (110.02 DI delayed
Source selection (see Terms and abbreviations
39).
Start and stop delay for supervision of main circuit
breaker DI3 feedback. After the delay a fault is given in
start and stop states if the command and the feedback
do not match.
Start and stop delay for supervision.
Defines the maximum charging time for the charging
function.
Maximum charging time
Defines the DC link voltage level for the charging
function. When the measured DC link voltage exceeds
the level, the main contactor/breaker can be closed.
Intermediate circuit DC voltage level in percent of the
nominal
Defines the maximum DC link voltage change rate
(dU/dt) for the charging function. When the change rate
falls below this maximum change rate limit, the control
program can close the main contactor/breaker. The
change rate is measured in 10 ms sample interval.
Maximum dU/dt change
Defines the start delay that delay the setting of the
charged state after the main circuit breaker has closed.
Without charged state the start command is blocked
from the modulator.
Start delay.
Defines a contactor change-over delay time for the
charging function. This is the delay between switching
of the charging contactor and switching on the main
contactor/breaker. The value can be positive or
negative. The negative value defines the time when both
contactors are closed. State 'charged' is set after
charging contactor has opened and possible start delay
parameter time has ended.
Delay between charging contactor opening and main
circuit contactor closing.
Enables the external charging function.
External charging disabled.
External charging enabled.
Disables charging counter. The charging counter can be
disabled in case the supply unit is equipped with
resistors that can withstand unlimited amount of
charging cycles.
Enables charging counter.
Disables charging counter.
Selects the event type for external charging overload
event.
The supply unit trips on fault
started and stopped three times within 5 minutes.
