4.1 LEDs description

4.1.1 Power indicator [(7)]
When the Power (green) LED is lit, the circulator is
supplied with power and the electronic devices are
operative.
4.1.2 Status indicator [(8)]
• If the "Status" LED is not lit, then the pump is
stopped or disabled and the pump motor is not
running.
• If the Status (orange) LED is lit, then the pump is
stopped and the pump motor is not operating due to a
non-blocking alarm
• If the Status (red) LED is lit, then the pump is stopped
or disabled and the pump motor is not running due to a
blocking error
• If the Status (green) LED is lit, then the pump is
operating
4.1.3 Remote control indicator [(9)]
The way the Remote LED is lit (permanently) or blinks,
depends on various settings and conditions as below
4.1.3.1 Condition 1
If no optional wireless or RS485 module is used
(referring to sec. 4.3.5.2, parameter "Module" is set to
value "None") and the protocol for the communication
bus is Modbus RTU (parameter "Protocol" is set to
value "Modbus")
• If the Remote LED is not lit, then the drive does not
detect any valid Modbus message on the terminals
provided for the communication bus
• If the Remote (green) LED is permanently lit, then the
drive both:
• detected a communication bus on the provided
terminals
• acknowledged the correct addressing
Electronic Drive Manual
• If the Remote (green) LED is blinking with 50% duty
cycle, then the drive:
• detected a communication bus on the provided
See sec. 4.3.3 terminals but has not been correctly addressed
See sec. 4.3.3
Reasons for this condition are the following:
See sec. 4.2
• If the Remote (green) LED switches from being
See sec. 4.2
permanently lit to being not lit, then the drive did not
See sec. 4.3.1
detect any valid Modbus RTU message (at least) for
the last 5 seconds
See sec. 4.1.1 • If the Remote (green) LED switches from being
permanently lit to blinking with 50% duty cycle, then
See sec. 4.1.2
the drive has not been correctly addressed (at least)
See sec. 4.1.3
for the last 5 seconds
4.1.3.2
If no optional wireless / RS485 module is used (refer-
ring to sec. 4.3.5.2, parameter "Module" is set to value
"None") and the protocol for the communication bus is
BACnet MSTP (parameter "Protocol" is set to value
"BACnet")
• If the Remote LED is not lit, then the drive did not
receive any valid request, coming from any BACnet
MSTP device, (at least) for the last 5 seconds
• If the Remote (green) LED is permanently lit, then the
drive is exchanging information with BACnet MSTP
device
4.1.3.3
If the optional wireless module is used (referring to sec.
4.3.5.2, parameter "Module" is set to value "Wireless")
• If the Remote LED is not lit, then the connection with
the wireless module is damaged or absent.
• If the Remote (green) LED is blinking with 10% duty
cycle, then the drive is exchanging information with the
wireless module.
4.1.3.4
If the optional RS485 module is used (referring to sec.
4.3.5.2, parameter "Module" is set to value "RS485")
• If the Remote LED is not lit, then either
• the connection with the RS485 module is damaged
or absent
• the drive didn't receive any valid request, coming
from any other external device, (at least) for the
last 5 seconds
• If the Remote (green) LED is blinking with 90% duty
cycle, then both:
• the RS485 module is correctly connected
• the drive is exchanging information with an
external device
