P8.13 Load Changeover
P8.01 - In applications with generating set, it enables or disables the operation of the periodic automatic test. This parameter can be modified directly from the
front panel without accessing set-up (see chapter Automatic Test) and its status is displayed by the relevant TEST LED
P8.02 - It defines the minimum time interval between the performance of an automatic test and the subsequent one, based on the programming of parameters
P8.03...P8.09 below. If on the day of period expiry the test is not enabled, the interval will be consequently extended.
P8.03...P8.09 - It enables carrying out the automatic test on the individual days of the week. OFF means that on that day the test shall not be performed. The
day is observed when the RTC is properly set.
P8.10 - P8.11 - It defines the starting time of the automatic test on a day. The RTC must be properly set.
P8.12 - It defines the duration of the automatic test in minutes.
P8.13 - It defines whether the automatic test is carried out only by starting the generator or whether load must also be transferred to the same generator (On).
REAL-TIME-CLOCK SET-UP
– With the unit in OFF-RESET mode, press keys H and B together for five seconds.
– Press keys A and C to scroll the RTC parameters.
– Press keys B and D to modify the setting of the selected parameter.
– Press key H to quit parameters set-up.
– For ATL20, after de-energising and energising again the RTC shall be reset. This situation is signalled by the flashing wording SET RTC and by the flashing
TEST LED .

DISPLAY OF STATISTICAL DATA

– ATL records a series of statistical data (operating times, operation counters, etc.) which are stored in a retentive memory even when the unit is de-energised.
– To access statistical data, press keys A and B together for 5 seconds, starting from any operating mode.
– Each data is shown by an acronym occupying both displays.
– To view the value of the corresponding data, press key B. Both displays will show the numeric value of the 6-digit data. After 3 seconds, the acronym will be
displayed again.
– For times shorter than 10000 hours, hours and minutes are displayed in the hhhh.mm format. Only hours are displayed beyond this value.
– The different data available may be selected through keys A and C.
– Press key H (OFF/RESET) to exit the function. The operating mode will not be changed.
– The operating times are identified by a acronym starting with letter t, while counters with C.
– A set of data may be cleared by pressing key D for 5 seconds (CLEAR is displayed).
– All times or all counters will be cleared, depending on the position from where the clear operation is performed.
– The following table lists the statistical data available.
Data acronym Description
t.L1 Loa Total time for load connected to Line 1 (Line 1 circuit breaker closed)
t.L2 Loa Total time for load connected to Line 2 (Line 2 circuit breaker closed)
t.no Loa Total time for load disconnected from both lines (both circuit breakers open)
t.L1 PrE Total time for Line 1 present (within limits)
t.L2 PrE Total time for Line 2 present (within limits)
t.L1 AbS Total time for Line 1 absent (out of limits)
t.L2 AbS Total time for Line 2 absent (out of limits)
t.totAL Total time of ATL operation
C.L1 Aut Count of number of operations (closing) - Line 1 circuit breaker in automatic mode
C.L2 Aut Count of number of operations (closing) - Line 2 circuit breaker in automatic mode
C.L1 Man Count of number of operations (closing) - Line 1 circuit breaker in manual mode
C.L2 Man Count of number of operations (closing) - Line 2 circuit breaker in manual mode
C.L1 Fau Count of number of failed operations - Line 1 circuit breaker (alarm A03)
C.L2 FAu Count of number of failed operations - Line 2 circuit breaker (alarm A04)
C.On OFF Count of total number of ATL energising/de-energising cycles
