ATySController A15 - 549779A - SOCOMEC
10.1. Triple power supply
The ATyS A15 can be supplied by 3 power sources:
AC – Power through the voltage sensing (terminals 103-104 for source 1 and terminal 203-204 for source 2) with power supply
range going from 184-300 V.a.c (in pulse mode) 200-300 V.a.c (in maintained mode) 50/60 Hz+/- 10%
DC - Auxiliary supply (optional), 10-30 V.d.c power supply using terminals 82-81.
CAUTION
The DPS output to the RTSE will not be functional when powering
through the DC auxiliary power supply.
10.2. Voltage sensing Inputs
The ATyS A15 includes dual single phase and 3 phase voltage sensing (terminals 103-106 and 203-206) designed to monitor 1
Phase supplies up to 300 V.a.c (L-N) and 3 phase +N up to 520 V.a.c (L-L).
The ATyS is designed to handle single phase and three phases with neutral networks, simply dene the correct conguration of
single phase / 3phase with neutral using the DIP switch 1 on the front of the controller (cf. Chapter 10-5 programming).
Sensing values measured will have a direct inuence on determining the availability of the main and alternate supplies as well as
the ATyS A15 automation.
The parameters monitored through the sensing are the following:
• Phase rotation
When both sources are available the controller will check that the phase rotation is identical on both sources. If the sources have
different phase rotations the source available LED will be blinking on both sources.
CAUTION
When only one source is available, the controller will automatically
accept the source regardless of the phase rotation order
• Frequency within set limits
The ATyS A15 will check that the frequency is within the limits congured through DIP switch 4. Frequency is checked on L1 only.
• Loss of the main or alternate power supply
Loss of supply depends on the nominal voltage and frequency congured together with the hysteresis (set in DIP switch 4)The
source will be considered as lost after the fail timer as counted down (set through dip switches 7 & 8 (0 / 3 /10 / 30 min).
• Return of main and/ or alternate power supply
Return of supply depends on the nominal voltage and frequency congured together with the hysteresis set. (Set in DIP switch 4).
The source will be considered as available when the return timer will have counted down (set through dip switches 6 (3s / 10s).
• Loss of Neutral
In a 3phase network with unbalanced loads the loss of the neutral will be detected.
