LEDs are lit if motor is running and its speed reaches the specific % step represented by each of
them.
If motor is running and its speed is lower than the absolute minimum (P27), the first LED blinks.
When motor is stopped, all arc’s LEDs are switched off.
7.3.4 Communication LED (1)
The way the
LED is lit (permanently) or blinks, depends on several settings and conditions
as below.
Condition 1
If no optional communication module is used and the protocol for the communication bus is
Modbus RTU (parameter P50 is set to value “Modbus”):
•
If
the
LED is not lit, then the drive cannot detect any valid Modbus message on the
terminals provided for the communication bus
•
If
the
COM
(green) LED is permanently lit, then the drive both detected a communication bus
on the provided terminals acknowledged the correct addressing
•
If
the
COM
(green) LED is blinking with 50% duty every second, then the drive detected a
communication bus on the provided terminals has not been correctly addressed.
Particular behaviors (in this condition) for this LED are the following:
•
If
the
COM
(green) LED switches from being permanently lit to being not lit, then the drive
didn’t detect any valid Modbus RTU message (at least) for the last 5 seconds
•
If
the
COM
(green) LED switches from being permanently lit to blinking with 50% duty every
second, then the drive has not been correctly addressed (at least) for the last 5 seconds.
Condition 2
If no optional communication module is used and the protocol for the communication bus is
BACnet MSTP (parameter P50 is set to value “BACnet”):
•
If
the
LED is not lit, then the drive didn’t receive any valid request, coming from any
other BACnet MSTP device, (at least) for the last 5 seconds
•
If
the
COM
(green) LED is permanently lit, then the drive is exchanging information with any
other BACnet MSTP device.
Condition 3
If the optional communication module is used:
•
If
the
LED is not lit, then the connection with the wireless module is damaged or absent
•
If
the
COM
(green) LED is blinking with 10% duty every second, then the drive is exchanging
information with the communication module.
7.3.5 Unit of measure LEDs (3) description
Speed
When Speed (pump impeller speed) is the measurement selected:
•
The current rotation speed measure, expressed as revolutions for minute divided by 10, is
displayed on the numeric display
•
The
10xRPM
LED is lit.
Head
When Head (hydraulic water head) is the measurement selected:
•
The current water head, measured expressed in bar or psi, of water head (dependent from
P41 value, see par. 7.5.4 ) is displayed on the numeric display
•
The
BAR
(or
PSI
) LED is lit.
7.4 Numeric display (6)
7.4.1 Main visualization
Off mode
OFF
is visualized when the contacts 11 and 12 (see par. 5.4) are not short circuited.
