Pump control and monitoring unit with
display in steel housing for 1 or 2 pumps.
Level detection performed using at least
one float switch, an analog sensor 4-20mA
or an integrated pressure sensor
(pneumatic or bubbler control) for motors
with DOL starting or star-delta starting.
1Using float switches, digital level switches or 4-20 mA analog sensors
2For bubbler control in BC housing, option O1 (master switch in BC housing) cannot be used.

Product benefits
▪Ample connection space allows straightforward
connection of pumps and sensors
▪Reliability provided by detailed information on the
display, including key measurement values and parameters
as well as "in operation" and general fault indication per
pump
▪Comprehensive functionality for high system availability
Selection information
Lightning protection
▪Electrical installations must be protected against
overvoltage (compulsory since 14December2018) (see
DINVDE0100-443 (IEC60364-4-44:2007/A1:2015, modified)
and DIN VDE 0100-534 (IEC 60364-5-53:2001/A2:2015,
modified). Whenever modifications are made to existing
installations, retrofitting a surge protective device (SPD) in
accordance with VDE is mandatory.
▪The associated lightning protection concept must be
provided by the operator or by a suitable provider
commissioned by the operator. Surge protective devices
can be found in the extended accessories range (type
series booklet 4041.51) as optional control unit
components.
Indoor installation:
▪A maximum cable length of 10metres should not be
exceeded between the surge protective device (usually
type 1, internal lightning protection) installed at the
service entrance and the equipment to be protected. For
longer cables, additional surge protective devices (type 2)
must be provided in the sub-distribution board upstream
of the equipment to be protected or directly in the
equipment itself.
▪Sensor cables that cross the boundaries between lightning
protection zones must be additionally protected by
suitable surge protective devices (e.g. when using a 4-
20mA immersion probe).
Outdoor installation:
▪Control units installed outdoors (e.g. in outdoor cabinets)
should always be equipped with Type 1 surge protective
devices (lightning protection), as they will not normally be
protected by a suitable upstream service entrance SPD.
