Mode of operation 3:
1 time relay with adjustable rate of delivery on
channel 1
•
Set jumper on printed circuit board to position 3 (default is position 1)
•
Put neutral conductor to terminal 1 and phase / mains (230 V AC) to terminal 2
•
Put controlling voltage (230 V AC) to terminal 3 („In1“).
•
NOTICE!
Controlling voltage terminal 3 and mains on terminal 2 must be cophasal!
•
With potentiometer P1 a time period between 6 and 60 seconds (select/selection/
selector switch SW in position 1) or between 60 and 600 seconds (select/selection/
selector switch SW in position 2) can be set.
•
With potentiometer P2 the rotor speed may be adjusted to a rate of delivery between
0.1 and 2 ml/min.
•
With a control voltage (230 V AC) at terminal 3 the pump delivers corresponding
to the preset operation time with constant rotor speed that is corresponding to
potentiometer P2.
•
On terminals 11 and 12 a suction line with float switch for supply tank empty
detection may be installed. If a supply tank empty is detected, the signal LED L3
blinks. Terminals 5 (neutral conductor) and 6 (phase) lead operation voltage to
switch on an external visual or audible warning signal. An optional LED in series
with a resistor (560 Ohm) between terminals 9 and 10 may be added.
