• Backup operation (factory default): the message
bCUP is flashing onto the Numeric Display (6).
In this configuration, only the master pump runs, while
the second pump starts in case of failure of the master
pump.
• Alternate operation: the message ALTE is flashing
onto the Numeric Display (6).
In this configuration, only one pump runs at a time.
The working time is switched every 24 hours so that
workload is balanced between both pumps. The
second pump starts immediately in case of failure of
the running pump. The 24 hour alternating time is
non-adjustable.
• Parallel operation: the message PArA is flashing onto
the Numeric Display (6).
In this configuration, both pumps run simultaneously
with the same set point. The master pump determines
the behavior of the full system and is able to optimize
the performance. To satisfy the required performance,
the master pump starts or stop the second pump
depending on the required head and flow.
• Forced parallel operation: the message FOrC is
flashing onto the Numeric Display (6).
In this configuration, both pumps always run
simultaneously at the same set point.
7. Press shortly the Parameter button (3) to confirm the
value selected.
The Numeric Display (6) stops flashing: the configura-
tion is finalized and the drive will proceed to the next
step as described in sec. 3, step 2.
Once the master pump is configured, the second pump
(slave) is then automatically configured by the master
pump. To verify this, the Remote (green) LED is
permanently lit.
In case the automatic configuration of the second pump
(slave) did not take effect (Remote LED not lit), repeat
the above procedure, from step 1 to step 4, configuring
the second pump to be a Dual Slave Pump.
NOTE:
Whenever two pumps, connected in Dual Pump
Operations, are required to communicate remotely with
a BMS or a generic external device, then the Optional
Communication Bus, described in sec. 2.5.7, must be
activated through the installation of an optional
module (see sec. 2.5.8) exclusively into the Master
pump of the couple.
Electronic Drive Manual
4.3.5.2 Communication settings
Each electronic drive can communicate remotely
through a built-in RS485 port, as briefly described in
sec. 2.5.6.
Referring to Figure 7 in the appendix, the communica-
tions settings are accessible following the subsequent
procedure.
1. Switch on the power supply to the pump
2. After few seconds, the drive will display the message
COMM.
3. While this message ("COMM") is displayed, press
shortly the Parameter button (3) in order to configure
the subsequent parameters:
• Baud Rate: the message bAUd "BAUD" is displayed
onto the Numeric Display (7), allowing the communica-
tion port baud rate to be set to a specific value.
Available values for this parameter are:
- 4.8 kbps
- 9.6 kbps (factory default)
- 14.4 kbps
- 19.2 kbps
- 38.4 kbps (recommended for BACnet)
- 56.0 kbps
- 57.6 kbps.
• Protocol: the message PrOT "PROT" is displayed
onto the Numeric Display (6), allowing the user to select
a specific protocol on the communication port.
Available values for this parameter are:
- Modbus NOd "MOD" (factory default)
- BACnet bAC "BAC".
• Address: the message Addr is displayed onto the Nu-
meric Display (6): by mean of it, the circulator address is
set to a specific value (1 is the factory default).
Available values for this parameter are:
- [1-247] (in case of Modbus protocol)
- [0-127] (in case of BACnet protocol)
• Module: the message NOdU "MODU" is displayed
onto the Numeric Display (6), allowing the user to select
one optional module in the drive.
Available values for this parameter are:
- None NONE (factory default)
- Wireless "WIFI"
- RS485 485
4. Press the Parameter button (3) to enter each sub-
menu, thus accessing to the next level.
5. Use the Setting buttons (5), in order to select the
desired value for every parameter
6. Press the Parameter button (3) to confirm and store
the value selected
7. Press the Control mode button (1) to exit each
sub-menu, thus returning to the previous level
If no buttons are pressed for 10 seconds, then the
pump exits the current menu and continues start-up
procedure. All the parameters changed without
confirmation are restored to former state.
