Connecting other Instruments to the K–2600
UV detector
Using the Event and Remote Sockets
On the rear panel side of the K–2600 UV detector two electrical
connector sockets are located, see [5.8] and [5.9] in Fig. 3 on page 9,
witch serve to send or receive signals from other instruments. The
event and remote interfaces are controlled by programs or the SETUP
menu.
Please avoid touching the electrical contacts of the socket lines.
Electrostatic discharges when touching the contacts could
damage the electronics of the device.
Assembling Plug Strips
For the electrical connections mentioned in the next chapters plug strips
with 2,3 or 4 connectors, enclosed in the accessories, may be mounted
as follows:

Assembling Plug Strips
1.
Insert the rounded end of the lever latch into the square opening
of the selected connector of the plug strip
2.
Press the catch down as indicated by arrow
3.
Insert the uninsulated end of the cable into the opening under the
catch
4.
Release the catch and remove the lever latch from the plug
The cable is now firmly anchored in the plug strip.
Event Socket
The photometer provides two control outputs. Event 1 (E1) is a relay
output, Event 2 (E2) a TTL (Transistor-Transistor-Logic) output. All
voltages have to be mounted between GROUND and the
corresponding event. The conditions 0, 1 or are programmed with the
numeric keys 0,1 or
.
The event socket can be used e.g. in combination with the fraction
collecting function of the photometer. A KNAUER 16-port switching
valve or a fraction collector can be connected to the relay output. The
relay will close when the corresponding event E1 is set to 1 in the
method and if the signal level chosen for fraction collection in the Setup
menu is exceeded, thus producing a short circuit that will switch the
valve to the next position.
