Furthermore, the LC 221 has six digital inputs for the following
functions:
– connecting an analogue sensor (4-20 mA or 0-5 V)
– connecting up to four level switches or pressure switches
instead of analogue sensors. An additional float switch can
be connected to the alarm input as backup for the analogue
sensors
– connecting a separate level switch to be used for flood
detection outside the Multilift MOG or MDG. Lifting stations
are often installed in a sump inside the basement - the
lowest point in the building. In case of e.g. groundwater
inflow or water pipe burst, an alarm will be indicated by the
controller.
– connecting a piezoresistive pressure sensor PCB
(pre-assembled)
– connecting an external alarm reset
– connecting the thermal switch of the motor.
For bus communication, the LC 221 can be equipped with a
GENIbus interface (available end of 2012) for connection to
Grundfos CIU 300 BACnet MS/TP.
For updates and further adjustments, a PC Tool can be
connected. See service instructions.
To allow for the situation that the normal power supply should fail,
a battery (accessory) can be installed which activates an acoustic
alarm (buzzer). The buzzer is activated as long as the fault exists.
It cannot be reset.
In case of sectional power failure, the common alarm output
which is a potential-free changeover contact can be used to
forward the alarm signal to a control room by means of an
external power source.
