Blanking flange
*
* A blanking flange is used to blank off the opening when one of the
pumps of a twin-head pump is removed for service to enable
uninterrupted operation of the other pump.
Pump type MAGNA3 (D)
Enclosure class Type 2
Insulation class F.
Supply voltage 1 x 115 V ± 10 %, 50/60 Hz, PE; 1 x 208-230 V ± 10 %, 50/60 Hz, PE
Two digital inputs
External potential-free contact.
Contact load: 5 V, 10 mA.
Screened cable.
Loop resistance: Maximum 130 Ω.
Analog input
4-20 mA (load: 150 Ω).
0-10 VDC (load: > 10 kΩ).
Two relay outputs
Internal potential-free changeover contact.
Maximum load: 250 V, 2 A, AC1.
Minimum load: 5 VDC, 20 mA.
Screened cable, depending on signal level.
Bus input
Grundfos Communication Interface Modules (add-on CIM modules) for
•GENIbus
• LonWorks
•Profibus DP
•Modbus RTU
• BACnet MS/TP
• Grundfos Remote Management.
Earth leakage current
I
leakage
< 3.5 mA.
The leakage currents are measured in accordance with EN 60335-1.
EMC EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and EN 61000-3-2:2006.
cos φ The MAGNA3 has a built-in active PFC (Power Factor Control) which gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
Consumption then the pump is stopped
1 to 10 W, depending on activity, i.e. reading the display, use of Grundfos GO Remote, interaction with modules, etc.
4 W, when pump is stopped and no activity.
Sound pressure level ≤ 43 dB(A)
