Alarm/Control Function
PSF210 is a programmable flow
controller designed for use with low-
viscose clear or translucent liquids,
transmitting IR light. The operating
principle is based on measurement
of liquid volume through light-weight
rotor, IR sensor and sophisticated
electronics for measurement and
control. PSF210 can be used as
a flow meter, flow transmitter with
pulse output, ON/OFF flow controller,
or alarm unit suitable for water
treatment and other applications.
Mounting
♦
Install PSF210 in the pipe system
using flexible hoses with ½" union
nuts. Do not over-tighten!
Make sure the arrow marking
♦
matches the flow direction!
♦
Slowly fill the system to avoid
air damaging the PSF210 rotor.
♦
Avoid uncontrolled air pressure
through the unit.
This may destroy the rotor!
Wiring
Connect PSF210 via the cable wires
as given on the left.
♦
PSF210 provides a 'window' type
alarm/control output function.
♦
Both AL and AH limits can be
programmed by the user.
Operating
Programming
♦
For programming, use the hidden key
below the LED display.
Press and hold the key until ALo or AHi
♦
appears on the display.
♦
Release the key to setup AL/AH alarm limit.
♦
Increase the blinking digit value by tapping
on the key and hold it to go to the next digit.
When all digits have been set, press and
♦
hold the key to store the value in the device
memory and exit programming mode.
Important notes:
♦
The fluid to be measured must be
compatible with the wetted parts!
Clean the medium-supply lines thoroughly
♦
before use.
♦
Use of 20
solid particles or medium contamination may
damage the flow sensor and/or influence
the measurement results!
♦
Mind that the operating principle
is based on volume measurement,
i.e. air in water is considered medium.
Operating
♦
When in operating mode, PSF210 indicates
current flow on the LED display within
specified range (see 'Specifications').
Alarm output stays off if the measured flow
♦
is between AL and AH and goes on outside
alarm 'window' (see 'Alarm/Control Function').
♦
Alarm LED lamp 'AL' lights when the alarm
output is on.
Display Messages
g+7 (over range) - display value over 999.

♦
L_V (under range) - display value below -99.
♦
OL (over load) - flow rate is over
specified range (see 'Specifications').
--- (initial check) - device initialization.
♦
Sto (store) - settings are stored in memory.
