ATySController C55/65 - 549866C - SOCOMEC
14.2. Specic Functions Menu
The controller integrates some specic functions that can be congured in this menu:
14.2.1. Manual retransfer
If this function is active (“YES”), when loads are supplied from the emergency source, the controller will not come back to
the normal source when this one comes back until a conrmation order is received through the display or through an input
(congured to do so). This applies also to TEST ON LOAD requests, a manual retransfer will be required to go back to the
prioritary source.
Every time the Manual Retransfer is requested, a pop-up will appear on the screen allowing the user to act immediately or it
can be dismissed and done any other time by using the menu CONTROL/MANUAL RETRANS:
If the dashboard key is pressed on the keypad while manual retransfer is needed, there will be a bottom message line on
screens 1.2 and 2.1 remembering the user that the retransfer approval is required.
14.2.2. In-phase transfer (C65 only)
The in-phase transfer is available for ATyS FT typology of RTSE or equivalent (2 position switch Class PC, I-II). It allows the
phase monitoring of the 2 sources, checking the Voltage, Frequency and Phase Angle continuously to make sure that the
sources are within the set synchronized window when performing the transfer from one source to the other.
All settings for the in-phase monitoring transition with the ATyS FT switch:
- Voltage range (0.5 - 20% of nominal voltage, default 2%)
- Frequency range (0.1-0.5Hz, default 0.2Hz)
- Angle (1-30°, default 7°)
- Dwell time / In phase time (time necessary to be in the correct synchro window to authorize transfer) (0-5000ms,
default 500ms)
- In-phase research delay / Fail To Sync timer (0-1200s, default 180s)
- Fail to sync option, to decide what to do when the research timer is over. USER CHOICE (pop-up is offered to decide
to transfer anyway or continue searching) or FORCE TRANSFER (transfer is performed at the end of research delay
independantly from the synchronism of sources)
At any time, the synchronism status of the 2 sources can be checked on the dashboard 2.2 STATUS / SYNC:
