COMMANDS MENU
– The commands menu permits the execution of occasional operations such as resetting measurements, meters, counter, etc.
– If the Advanced-level password has been entered, the commands menu can also be used to perform some automatic operations that are useful for configuring the instrument.
– The following table lists indicates the functions available in the commands menu, divided by access level required.
– Once the required command has been selected, press to execute it. The device will prompt for a confirmation. Pressing again will execute the command.
– To cancel the command execution, press MENU.
– To quit the commands menu, press
s
and
t
simultaneously.
WIRING TEST
– The wiring test permits verification of the correct installation of the energy meter.
– In order to run the test, the energy meter must be connected to an active system with the following conditions:
• Three-phase system with all phases present (V > 187VAC PH-N)
• Minimum current flow in each phase > 1% of the CT full scale set
• Positive flow of energies (i.e. a normal system where the inductive load draws power from the supply).
– To launch the test execution, enter the commands menu and select command C.16, according to the instructions in the Commands Menu section.
– The test allows to verify the following points:
• Reading of the three voltages
• Phase sequence
• Voltage unbalance
• Reverse polarity of one or more CTs
• Mismatch between voltage/current phases
– If the test does not succeeds, the display shows the reason of the failure.

NOTES
1. Recommended fuses: F1A (fast).
2. The S2 terminals are connected to each other internally.
M14 – OUTPUTS (OUTn, n=1..2) UoM Default Range
P14.n.01 Output function OFF OFF – ON – SEQ
LIM – ALA – PUL
P14.n.02 Channel number (x) 1 1 - 4
P14.n.03 Normal status OFF OFF - ON
P14.n.04 ON delay s 0.0 0.0-6000.0
P14.n.05 OFF delay s 0.0 0.0-6000.0
Note: this menu is divided into 2 sections, for outputs OUT1..2
P14.n.01 – Output function:
OFF – Output disabled.
ON – Output always activated when the meter is powered up.
SEQ – Output activated in case of phase sequence error.
LIM - ALA – Output activated in case of limit overcome or alarm presence.
PUL – Output used as pulse generator as defined in M11.
P14.n.02 – Output normal status. Permits inversion of the activation logic.
P14.n.03 – P14.n.04 – Output activation – deactivation delays.
