With active control voltage on terminal 4 („In 2“) terminals 5 (neutral) and 6
(phase) are active (230V AC). An optional LED is in series with a resistor (470
Ohms) between terminals 9 and 10. This special mode is intended to gather the
error state of any device of a multiple device dosage station to the last device, which
forwards the error state to a computer system or an additional external warning
signal.
Mode of operation 4:
Time relay on channel 1 and adjustable rate of
delivery on channel 2
•
Set jumper on printed circuit board to position 4 (default is position 1)
•
Wiring of the device in accordance to the wiring diagram ”Mode of operation 2".
Attach neutral conductor to terminal 1 and power supply (230 V AC) to terminal 2.
Attach control current 1 (230 V AC) to terminal 3 (”In1") and control current 2 to
terminal 4 (”In2").
Caution!
Power supply on terminal 2 and control current at terminal 3 and terminal 4
must be in phase!
•
With potentiometer P1 a time period between 6 and 60 seconds (selector switch
SW in position 1) or between 60 and 600 seconds (selector switch SW in position
2) can be set. With a control current (230 V AC) at terminal 3 the pump delivers
corresponding to the preset period of time (P1, SW).
•
With potentiometer P2 the rotor speed can be set to operate at a rate of delivery
between 0.1 and 2 ml/min. As long as the control current (230 V AC) at terminal 4
is active, the pump operates at the adjusted rate of delivery.
•
IMPORTANT!
In case of simultaneous control current, channel 1 (”In1") has priority.
•
On terminal 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.
Electrical connection
•
All installation must be done with the power supply disconnected.
•
Installation should proceed in accordance with local rules and regulations.
•
Putting the unit into service and carrying out adjustments must be left entirely to
appropriately instructed personnel.
•
If the machine control doesn’t supply a special terminal for the pump, the device
must be installed with a multi-polar switch with a contact distance of at least 3 mm.
•
Electrical connection should proceed in accordance with the terminal designations
in the device.
Putting into service Start-up
After connecting the device to the power supply and activation of the control signal on
terminal 3 („In1“), the pump/operates steadily with the rate of delivery preset by the
CAUTION!
IMPORTANT!
