60 WILO SE 2018-12
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
4.6 Type key
Example: Wilo-Control EC-L 2x12A-MT34-DOL-WM-X
EC
Easy Control switchgear for fixed-speed pumps
L
Level-dependent control of pumps
2x
Max. number of pumps that can be connected
12A
Max. rated current in amperes per pump
MT34
Mains connection:
M = alternating current (1~220/230V)
T34 = three-phase current (3~380/400V)
DOL
Pump activation type: Direct
WF
Wall fixation
X
Versions:
EMS = without main switch (mains isolator must be provided by the cus-
tomer!)
IPS = with integrated pressure transducer for direct connection of a dy-
namic pressure bell
4.7 Operation on electronic start-up
controllers
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!
4.8 Installation in potentially explos-
ive atmospheres
The switchgear does not have its own explosion protection class. It may not be installed
in potentially explosive areas.
