8.1. Triple power supply
HZI815 or HIZ825 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 VAC (in pulse mode) 200-300 VAC (in maintained
mode) 50/60 Hz+/- 10%
DC - Auxiliary supply (optional), 10-30 VDC 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.
8.2. Voltage sensing Inputs
HZI815 or HIZ825 includes dual single phase and 3 phase voltage sensing (terminals 103-106 and 203-
206) designed to monitor 1 Phase supplies up to 300 VAC (L-N) and 3 phase +N up to 520 VAC (L-L).
HZI815 or HIZ825 is designed to handle single phase and three phases with neutral networks, simply
define the correct configuration 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 influence on determining the availability of the main and
alternate supplies as well as HZI815 or HIZ825 automation.
The parameters monitored through the sensing are the following:
• Phase rotation
When both sources are available the controller will check that both sources have the same phase
rotation.
If the two sources have different phase orders the source LED (1 & 6) will blink , the fault LED will light
up and the sources will be considered as not available (switch will not transfer from the current position
to the opposite source).
If only 1 source is available the product will not check the phase rotation order.
CAUTION
When only one source is available, the controller will automatically accept the source regardless of the
phase rotation order.
• Frequency within set limits
HZI815 or HIZ825 will check that the frequency is within the limits configured through DIP switch 4 or
through communication (only for HZI825) (cf. configuration chapter configuration). Frequency is checked
on L1 only.
• Loss of the main or alternate power supply
Loss of supply depends on the nominal voltage and frequency configured 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 configured 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 3 phase network with unbalanced loads the loss of the neutral will be detected.
