Loss of neutral: will be detected in all cases except
for balanced networks with balanced loads.
In Breaker mode: the use of undervoltage release
(see wiring diagram) can prevent this situation.
Power Supply:
The HZI855 controller is Self-powered from the voltage sensing of any
available source, and may also be powered (as a backup from saved
source) from the DC auxiliary power input (24 VDC).
Dual Power Supply / Sensing
The HZI855 controller will be automatically supplied from the voltage
sensing connectors of both sources thanks to an internal DPS (dual power
supply) module that in case main source failure, will immediately switch to
the secondary source supply the device.
NOTE:
The nominal auxiliary power supply feeding the sensing terminals
must be within the limits of 88
➡
576 VAC.
NOTE: The HZI855 must include a SCPD such
as fuses on each phase of the voltage sensing
control wiring.
1A gG fuses are recommended.

Default configuration for Inputs and Outputs for "HIB4xxM" mode:
IN1: Switch is in position 1
IN2: Switch is in position 2
IN3: Switch is in position 0
IN4: Inhibit
IN5: Manual restransfer
IN6: RTSE in manual
OUT1: Order to switch in position 1
OUT2: Order to switch in position 2
OUT3: Order to switch in position 0
OUT4: S1 Available
OUT5: S2 Available
OUT6: Order to start Genset
* The use of this input is optional, when used IN6 should be configured
to "COVER OPEN" in mode "NC".
This configuration is defined with source I as the priority source.
This diagram covers most application cases, the inputs and outputs
are configured by default for this installation.
For single phase networks,
the neutral has to be
bridged from N to L2
