OPERATING AND MAINTENANCE MANUAL
SPEEDBOX SERIES ELECTRONIC VARIATOR
2. MASTER-SLAVE OPERATION
The MASTER-SLAVE group consists of a SPEEDBOX device configured as MASTER
responsible for the control of the group and a SPEEDBOX configured as SLAVE controlled by
the master device. Due to the alternation of the system, the SPEEDBOX configured as 'master'
starts the first cycle as the main device - its pump is the first to start - but in the following
cycle it becomes the auxiliary - its pump is the second to start - and so on. Therefore, the fact
that a device is configured as MASTER implies the control of the group but does not prevent
it from alternatively functioning as an auxiliary device. Each Speedbox will be provided with
its own pressure transmitter.
3. GENERAL CHARACTERISTICS
•
Frequency inverter for pump control.
•
Wall mounting.
•
Pump control and overcurrent protection system.
•
Protection system against pump running dry due to lack of water.
•
ART function (Automatic Reset Test). When the device is stopped due to the intervention
of the protection system due to lack of water, the ART tries, at programmed intervals, to
switch on the unit to see if the water supply has been restored.
•
Automatic reset system after power failure. The system is activated in the same state
as before the interruption, maintaining the configuration parameters (see chapter
'CONFIGURATION').
•
STC (Smart Temperature Control) function. When the temperature of the
electronic board exceeds 85 ºC, it automatically decreases the pump rotation
frequency,
reducing
External pressure transducer (on request).
•
Connections for minimum water level detection in the suction tank. This system is
independent of the dry run safety system. Its use is optional.
