WARRANTY
This product is covered by a warranty against material and manufacturing defects for a 24
months period from the manufacturing date.
The warranty does not cover the defects that are due to:
• Negligent and improper use
• Failures caused by atmospheric hazards
• Acts of vandalism
• Wear out of materials
• Firmware upgrades
Akse reserves the right, at its discretion, to repair or substitute the faulty products
The warranty is not applicable to the products that will result defective in consequence of
a negligent and improper use or an operating procedure not contemplated in this manual.
RETURN AND REPAIR FORMALITIES
Akse accepts the return of instruments for repair only when authorized in advance. The
transport costs are at customer charge.
RE-SHIPPING OF REPAIRED PRODUCT
The terms for re-shipment of repaired products are ex-works, i.e. the transport costs are
at customer charge.
Products returned as detective but found to be perfectly working by our laboratories, will
be charged a flat fee to account for checking and testing time irrespective of the warranty
terms.
SAFETY
This instrument was manufactured and tested in compliance with IEC 61010-1 CAT III-
300V class 2 standards for exercise voltages up to 300 Vac rms phase to neutral.
In order to maintain this condition and to ensure safe operation, the user must comply with
the indications and markings contained in the following instructions:
• When the instrument is received, before starting its installation, check that it is
intact and no damage occurred during transport.
• Before mounting, ensure that the instrument operating voltages and the mains
voltage are compatible then proceed with the installation.
• The instrument power supply needs no earth connection.
• The instrument is not equipped with a power supply fuse; a suitable external
protection fuse must be foreseen by the contractor.
• Maintenance and/or repair must be carried out only by qualified, authorized
personnel
•Ifthereiseverthesuspicionthatsafeoperationisnolongerpossible,theinstrument
must be taken out of service and precautions taken againstits accidental use.
• Operation is no longer safe when:
1) There is clearly visible damage.
2) The instrument no longer functions.
3) After lengthy storage in unfavorable conditions.
4) After serious damage occurred during transport
The instruments must be installed in respect of all the local regulations.
OPERATOR SAFETY
Warning: Failure to observe the following instructions may lead to a serious danger of
death.
• During normal operation dangerous voltages can occur on instrument terminals and
on voltage and current transformers. Energized voltage and current transformers
may generate lethal voltages. Follow carefully the standard safety precautions while
carrying out any installation or service operation.
• The terminals of the instrument must not be accessible by the user after the installation.
The user should only be allowed to access the instrument front panel where the
display is located.
• Do not use the digital outputs for protection functions nor for power limitation functions.
The instrument is suitable only for secondary protection functions.
• The instrument must be protected by a breaking device capable of interrupting both
the power supply and the measurement terminals. It must be easily reachable by the
operator and well identified as instrument cut-off device.
• The instrument and its connections must be carefully protected against short-circuit.
Precautions: Failure to respect the following instructions may irreversibly damage to the
instrument.
• The instrument is equipped with PTC current limiting device but a suitable external
protection fuse should be foreseen by the contractor.
• The outputs and the options operate at low voltage level; they cannot be powered by
any unspecified external voltage.
• The application of currents not compatible with the current inputs levels will damage
to the instrument.

ALARM SETTING EXAMPLES
NOTE n.2
POWERS Integration time of the average value (AVG) and max. value (MD) for power (from 1
to 60 minutes)
CURRENTS Integration time of the average value (AVG) and max. value (MD) for power (from 1
to 60 minutes)
NOTE n.3
NORMAL Classic alarm with reference to a fixed or max / min threshold, with applicable
hysteresis and delay. The “ AVG” parameter is not used.
DERIV The “THRE” parameter becomes a percentage value.
The instantaneous value applied to the alarm on “MEAS“ will be compared with its
averaged value obtained depending on the time set on “AVG”.
When the instantaneous value combined to the alarm differs in “more then“ (if set
“MAX”) or in “less then“ (if set “MIN”) compared to the average value (“AVG”) of the
percentage set on “THRE”, the alarm triggers. With applicable hysteresis and delay.
The “AVG” parameter is used.
NOTE n.4
MAX Alarm configuration in “excess” according to the conditions set.
MIN Alarm configuration in “excess” according to the conditions set.
NOTE n.5
MEAS Indicates on which register (and on which measure) the alarm is reported.
See table n.1 (Input Register).
THRE Alarm threshold in absolute value, except the “DERIV” value where the value inserted
becomes a percentage.
NOTE n.6
AVG Parameter to be used in the sole “DERIV” mode. Floating window amplitude ( in se-
cods) used for creating a reference value to which compare the instantaneous value.
NOTE n.7
NORMAL The output remains exited during all the alarm, after all it falls.
HOLD The output remains exited untill the manual reset made through Modbus
PULSE-L The output generates a 500ms pulse on the alarm triggering.
PULSE-S The output generates a 100ms pulse on the alarm triggering.
