User limit LIMx
The ATC6500 provides the option of specifying 16 user limits.
The LIMx limits are internal variables whose status is dependent on whether one of the
measurements performed by the system has exceeded the limit specified by the user
(example: Voltage between L1-L2 higher than 400 V).
Note
Limit settings
The conditions for transfer between the two sources are defined in the control thresholds in
menu P09. User limits LIMx serve to implement advanced functions.
For each LIMx limit both the reference measurement and the reference source must be set.
The following functions can be defined for exceeding the upper and lower thresholds of the
limits:

Description
OFF
The user limit is deactivated.
V L1-N
The voltage of L1-N serves as a source for the limit threshold.
V L2-N
The voltage of L2-N serves as a source for the limit threshold.
V L3-N
The voltage of L3-N serves as a source for the limit threshold.
V L1-L2
The voltage of L1-L2 serves as a source for the limit threshold.
V L2-L3
The voltage of L2-L3 serves as a source for the limit threshold.
V L3-L1
The voltage of L3-L1 serves as a source for the limit threshold.
V L-N EQV
The mean value of all voltages between L-N serves as a source for the limit threshold.
V L-L EQV
The mean value of all voltages between L-L serves as a source for the limit threshold.
Hz
The frequency serves as a source for the limit threshold.
ASY V L-L
The voltage unbalance of L-L serves as a source for the limit threshold.
ASY V L-N
The voltage unbalance of L-N serves as a source for the limit threshold.
VDC BATT
The voltage of the DC source serves as a source for the limit threshold.
CNT x
The user-defined counter CNTx serves as a source for the limit threshold.
CNT AUT
The defined counter CNT AUT serves as a source for the limit threshold.
CNT MAN
The defined counter CNT MAN serves as a source for the limit threshold.
A 03
The occurrence of the alarm A03 (Source 1 circuit breaker timeout) serves as a source for the limit
threshold.
A 04
The occurrence of the alarm A04 (Source 2 circuit breaker timeout) serves as a source for the limit
threshold.
Time Load
The time for which the power is supplied by the selected power supply source serves as a source for the
limit threshold.
No Load
The total time without a power supply serves as a source for the limit threshold.
Switch off
The source for the limit threshold is the number of times that the ATC6500 has been de-energized.
