The DIAM3200 constant current regulators described in this manual have been designed to
be installed on the levelled oor with adequate atness and strength characteristics.
The normal installation condition is a xed, stable and non-slip oor, free of protuberances,
hollows or inclined planes, designed and constructed with characteristics suitable to the
actual operating conditions.
The positioning of the unit must guarantee easy access to complete use and maintenance
operations.
The supply circuits, of suitable technical specications, can be positioned within pipes, ducts
or cable trays that comply with the applicable regulations in force.
In the same conduit, without separations, no conductors referring to dierent services must
be laid (this prohibition is extended to all connecting lines, even if the conductors operate
at the same operating voltage).

●WARNING:theconstantcurrentregulatorcontinuesnormaloperationbutalertstheoperatorthataproblem

●ALARM:theconstantcurrentregulatorisunabletocontinuenormaloperationandinterruptsthecurrent
supplyduetoaninternalfault(e.g.alarmofoneoftheovercurrentthresholdlevels)oranexternalfault
(e.g.opencircuit).
When a fault occurs, prompt action must be taken to identify the cause of the fault and
eliminate the problem.
The system can only be reset by means of a manual reset (STOP key).
The unit preserves the memory of messages detected during operation even in the event of
the supply voltage. When switching the unit back on, proceed to resolution and restoration
of all messages in the memory.

If the error condition is temporary and the input voltage value returns within the operating

If the unit shuts down and goes into alarm status, when the voltage values return to within
a narrow range (Uin ±10%) the unit restarts. The unit preserves the memory of the alarm
message, which must be reset manually.

The cables necessary for the functioning of the unit are not included in the supply. It is the
customer’s responsibility to arrange appropriate certied equipment to connect the units.
Before connecting the unit, check that the unit conguration is compatible with the actual
system conditions.
Always check the supply voltage and the load installed on the series circuit.

regulator.
For the construction of the supply circuits and for the series circuits, refer to the requirements
of the relevant Standards.
For the conformity of the light xtures supplied by the constant current regulators through
the series circuits, refer to the specic product certications.
Do not connect the constant current regulator to circuits which have not previously undergone
high-voltage insulation tests or to cables which show signs of damage or deformation.
Before making connections, check that the series circuits and light xtures are correctly
congured and installed.
As an alternative to the earth fault detector integrated in the regulator (EFD option), optional
devices are available for monitoring the series circuit (IRM), able to generate warning and
alarm messages to be integrated in the mandatory reporting for the proper management and
maintenance of the airport (FAA AC 150/5340-30).
These devices are a useful accessory for the management of faults and for an easier
identication of the cabin problems.
For more information, contact technical support.

Before proceeding with the operation, check the conditions of the device:
●checkthatthemechanicalxingofthecomponentsaresteady;
●checkthattheinternalconnectionsareproperlytightened;
●checkthattheinternalequipotentialconnectionsareallwellrealized.
Always use lifting equipment of suitable characteristics: before handling the load, check
the weight and dimensions of the load to be lifted, verifying the correct positioning of the
centre of gravity.
Do not attempt to lift the machine using anchor points other than those indicated.
