3. Introduction
HZI815 or HZI825 “ATS Controller” in association with an RTSE (Remote transfer switching equipment
forms an ATSE (Automatic transfer switching equipment), the ATSE formed by the association is
designed for use in power systems for the safe transfer of a load supply between a normal and alternate
source. When associated with HIB4xxM RTSE the changeover is done in open transition insuring
full compliance with IEC 60947-6-1, GB 14048-11 and other international standards as listed. As a
standalone product the HZI815 or HZI825 is compliant with IEC 61010-2-201 and is compatible with
use with PC and CC type RTSE.
HZI815 or HZI825 “ATS Controller” Ensures:
• Monitoring of the availability of a Normal and Alternate source
• Supply to the controller and switch from the Normal or Alternate source
• Transfer orders to the RTSE and position reception from the RTSE
• A complete solution fully tested with HIB4xxM RSTE
• Intuitive HMI for emergency/local operation
• Clearly visible and indicated HMI
• Suitable for door mounting on the enclosure or DIN Rail mounting inside the enclosure
• Inherent electrical interlock between position orders
• Monitoring of the RTSE stable positions (I – 0 – II)
• Straightforward installation with eective ergonomics
• Power supply continuity for most Utility / Generator or Utility / Utility network applications when linked
to an RTSE (Remotely operated transfer switches).

8. HZI815 or HZI825 operating modes
HZI815 or HZI825 has 3 distinct working modes, the working modes are selected using the HMI button
or by using the 63A/64A input.
The 3 working modes are working as described below:
• Auto mode
In this mode the controller will automatically give orders to the RTSE connected to switch to the
correct position according to the settings selected.
In this mode, the manual order buttons , , are disabled.
This mode is activated when the LED 7 is ON (fixed). To access this Mode make sure that you are in
manual mode (the LED 7 is OFF and that the fault LED (12) or the TEST LED (8) are not activated) and
then press the button for 3 seconds, the LED 7 should then turn ON.
• Manual mode
In this mode the manual orders buttons , , enable manual orders to switch respectively
to position I , 0 or II.
This mode is activated when the LED 7 is OFF and the LED 12 is OFF and that the fault LED (12) or
the TEST LED (8) are not activated. To switch from AUTO mode to manual mode, press the button
for 3 seconds
• Inhibit mode
In this mode both the Automatic transfer and manual orders will be blocked. This mode is activated
when the input 63A/64A is OPEN.
In this mode the fault LED (12) will be blinking, and AUTO LED will be OFF. To leave the inhibit mode
close the 63A/64A input, the controller will return to the last working mode (Automatic or Manual).
