3.3. How it works

The microcontroller-controlled Easy Control
switchgear is designed for control of a pump
with a fixed speed capable of level-dependent
switching.
Level detection is via two-position control with
a float switch, which needs to be provided by
the customer. The pump is activated/deactivat-
ed automatically depending on the fill level. If a
follow-up time is required, this can be set via a
potentiometer.
On reaching high-water level (detected via a sep-
arate float switch), a visual and audible warning is
emitted and forced switch-on of the pump takes
place. The collective fault signal (SSM) is active.
The current operating state is indicated via LEDs
on the front side. Operation is via 4 pushbuttons
on a control panel attached at the side.
Faults are indicated visually via LEDs and audibly
via an integrated buzzer. The last error is stored in
the fault memory.

3.4. technical data

3.4.1. inputs
• 2 digital inputs for float switches (pumps ON/OFF,
high water)
• 1 input for thermal winding monitoring with
bimetal temperature sensor. Connection of PTC
sensors is not possible!
3.4.2. outputs
• 1 potential-free contact for SSM

3.6. options

By inserting a rechargeable battery (available
as an accessory) alarm signals can be emitted
independent of the electricity network in case of
a fault. An audible constant tone will be emitted
as an alarm.
