8.2 Frequently asked questions
A series of clicks is always heard at around noon. What does that mean?
ATICS® carries out a coil trigger test once a day. The time is calculated as follows: 12:00:00 o'clock +
(own BMS bus address * 10 s).
If configured to "Generator" for the redundant line on settings menu 1 "Changeover", then the coil
test will only be run for Line 2 when Line 2 has a voltage.
When the "TEST -> Generator" is run, the coil test is carried out for Line 2 directly after starting the
generator.
A thin vertical line runs across the display. Is the display defective?
No. The "Refresh function" of the display is being active refreshing the contents indicated.
Why doesn't ATICS® display the pre-set time?
The time of the ATICS® is set by the BMS bus master.
The time for the ATICS® only is required in that rare case when no BMS bus is used. In this case, the
ATICS® shows the fault message "No Master".
How can I deactivate the meassage "No Master?
ATICS® is designed for applications where functional safety is of top priority. Therefore, this message
is necessary.
For applications, where functional safety plays a minor role, the master monitoring function can be
switched off in the menu "Settings > Interface > Failure monitoring" (see page 77).
ATICS® does not change over. In the last line on the display it indicates: "t(0): xx s".
ATICS® is waiting for the time delay t(0) to elapse and displays the remaining time in seconds. Only
then can the ATICS® change over. The time delay can be due to the following reasons:

ATICS® is just switching. The adjusted time delay in switch position "0" (dead time) takes several
seconds (see "Settings menu 1: Changeover" on page 67)

ATICS® has just been supplied with voltage. After the expiry of the time delay, ATICS® will be
ready for operation.
Within a short period of time, ATICS® carried out more than 12 changeover operations. The time de-
lay is required to cool the system.
ATICS-4-DIO shows the alarm message "Phase sequence". What should be done?
Already during the commissioning of the ATICS-4-DIO, make sure that both the preferred line and
the redundant line have the same phase sequence direction (clockwise).
This is particularly important when the performance of connected three-phase loads is dependent
on the phase sequence direction. Example: The three-phase motor runs in the wrong phase se-
quence direction (counter-clockwise).
Despite the alarm message "Phase sequence", the ATICS® changes over from the preferred line to the
redundant line in the event of failure of the preferred line. This ensures continued operation of loads
that are not affected by the phase sequence.
