Product description
Inputs
▪ Analogue input:
– 1 x level sensor 4 – 20 mA
▪ Digital inputs:
– 2 x or 3 x float switches for level measurement
NOTICE! A max. of 2 pumps can be actuated with level measurement using a float
switch!
– 1 x float switch used for sensing high water level
– 1 x float switch used for sensing dry running level/low water level
▪ Pump monitoring:
– 1 x input/pump for thermal winding monitoring using a bimetallic strip.
NOTICE! PTC sensors cannot be connected!
– 1 x input/pump for leakage detection using a moisture probe
▪ Other inputs:
– 1 x Extern OFF: for remote switch-off of all pumps
In "fill" operating mode, dry-running protection is realised via this input.
Outputs
▪ Potential-free contacts:
– 1 x changeover contact for collective fault signal
– 1 x changeover contact for collective run signal
– 1 x NC contact for every pump for individual fault signals
– 1 x NO contact for every pump for individual run signals
▪ Other outputs:
– 1 x power output for connecting an external alarm signal (lamp or horn)
Connection value: 24 V DC, max. 4 VA
– 1 x analogue output 0 – 10 V for displaying the actual level value
Example: Wilo-Control EC-L 2x12A-MT34-DOL-WM-X
Easy Control switchgear for fixed-speed pumps
EC
Level-dependent control of pumps
L
Max. number of pumps that can be connected
2 x
Max. rated current in amperes per pump
12 A
Mains connection:
MT34 M = alternating current (1~220/230 V)
T34 = three-phase current (3~380/400 V)
Pump activation type: Direct
DOL
Wall fixation
WF
Versions:
EMS = without main switch (mains isolator must be provided by the cus-
X tomer!)
IPS = with integrated pressure transducer for direct connection of a dy-
namic pressure bell
The switchgear must be connected directly to the pump and the mains. Intermediate
switching of additional electronic start-up controllers, e.g. a frequency converter, is not
permitted!
The switchgear does not have its own explosion protection class. It may not be installed
in potentially explosive areas.
