Installation and starting instruction manual
SYCLOPE TRACE’O
®
9)
Connection of the flow control entry sensor (Flsw) or low level detection tank
The
SYCLOPE TRACE’O
®
controller has a flow-control input used to check for the presence of water
circulating in the measurement chamber. This input is designed to receive a NO contact (normally
open).
In case of absence of flow or insufficient flow, the dosages of chemicals and other types of regulation
will be suspended.
In case of nonuse of the flow-control function, this input can be also used to control the low level of
chemical product tanks and will cause the stop of the dosage of the corresponding products when the
low level is reached. In this last case, the function NO (Normally open) or NC (Normally closed) is
programmable.
a)
Case of a connection to a potential free dry contacts (2wires)
The detector must be free of potential contacts.

b)
Case of a connection to an electronic contact (3 wires)
The electronic detector must be NPN type, with open collector (or open drain)
working with 12VDC power.
