Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
HS315 performs a time-dependent current protection (therefore, the higher the current
overload, the shorter the reaction time) The curve used is called EXTREMELY INVERSE with
function I
2
t. See description for anomaly 006.
The protection will be activated exactly after this time (P.9755) if the current is constantly equal
to the threshold P.9754 multiplied by
2
, in a shorter time if the current is higher; in a longer
time if the current is lower; and it will never do if the current is lower than P.9754
Type: Latched warning
Related parameters: P.9751 Loads current hysteresis.
P.9756 Loads short circuit threshold.
P.9757 Loads short circuit delay.
To disable: P.9757 = 0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This protection is activated if the measure of the loads current remains continuously above to
threshold P.9736 for time P.9737.
Type: Latched warning
Related parameters: P.9751 Loads current hysteresis.
P.9758 Loads reverse current delay.
P.9759 Loads reverse current action.
To disable: P.9759 = 0
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This protection is activated if the loads current is negative and has an absolute value
continuously above threshold P.9758 for time P.9759.
Type: Warning
Related parameters: P.0141 Number of DITEL modules.
P.0142 Number of DITEMP modules.
P.0143 Number of DIVIT modules.
P.0144 Number of DANOUT modules.
To disable: -
Enabled in: MAN, AUTO, TEST, REMOTE START
Override: -
This warning is enabled if a number of modules other than zero has been set (in parameters
P.0141, P.0142, P.0143 or P.0144). It is activated if one or more controllers connected to CAN-
BUS (EXBUS) are not available. Page S.02 shows the module that does not communicate.
Type: Warning
Related parameters: P.0142 Number of DITEMP modules.
P.0143 Number of DIVIT modules.
