With potentiometer P2 a time period between 1 and 20 seconds can be set.
•
With the control voltage „In2“ (230 V AC) at terminal 4, the perestaltic pump
operates for the set time at constant rotor speed (capacity approx. 6 ml/min.
•
In case the control voltages ”In1" or ”In2" get inactive before the adjusted operation
time is terminated, the operation is stopped immediately. If this/premature stopping
of the operation is not desired, ”
operation mode B“
must be selected. For this
mode, 3 additional pins on the printed circuit board near the LED for the warning
signal are designated. A jumper must be set that the pin marked with ”B“ and the
pin in the middle are connected. In this operation mode the operation time is
started with an impulse that last at least 400 ms. A premature termination of
operation will not happen.
•
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.
•
NOTICE!
If no suction line with float switch is installed, terminals 11 and 12 must stay
bridged!
