EXHAUST connector
Connector for connecting a “retain” pressure source or for EXHAUST. If no “retain” pressure
is connected, the system is exhausted as long as no pressure is applied to the pipette.
(4)
IN connector
Connector for connecting the filtered, dry and oil-free gas source. The gas source must be
filtered by a 5 µm filter element.
Important
: Do not connect sources of OXYGEN or COMBUSTIBLE gases!!
Note
: npi recommends an input pressure of 1 bar / 14 psi more than the maximum output
pressure.
(5)
Pressure regulator
Rotary knob for regulating the pressure of the ejection channel. The pressure is indicated by the
manometer (#
1
).
(6)
OUT connector
Connector for connecting the injection micropipette, or for connecting the tubing to external
valve, e.g. the micropipette holder
micro
JECT. The EJECT pressure is supplied to this
connector.
(7)
EXTERNAL VALVE connector (optional)
Connector for the electrical connection of the external valve.
(8)
TIMING MONITOR
BNC connector providing a TTL signal that indicates the status of the regulated injection valve
(HI = valve open, LO = valve closed).
(9)
PRESSURE MONITOR
BNC connector monitoring the pressure output; sensitivity: 1 V / bar or 0.1 V / psi, respectively.
(10)
REMOTE CONTROL connector
BNC connector for connecting a remote control, e.g. a pushbutton.
(11)
TTL INPUT
BNC connector for connecting a TTL signal for EXTERN operation or for using the internal
