Event and remote socket connections
EVENT 1 :
Relay:
Possible conditions are :
Contacts open
0
Contacts closed
1
Pulse: (contacts closed for 500 ms)
EVENT 2 :
TTL
(max. consumption 40 mA, U
CEmax
= 24 V).
Possible conditions are:
Low (< 500 mV)
0
High (> 2 V)
1
Pulse (> 2 V for 500 ms)
ERROR IN:
when receiving a 0 V error signal, the message
Error
signal was detected
appears on the display, programs
are stopped and the lamp is switched off.
ERROR OUT:
an open collector output remains active so long as an
error is detected, e.g. the lamp does not start.
START IN:
if an electrical signal is received, a prgram or link is
started, either by a low signal or by a short circuit
START OUT:
an open collector output is active foür 500 ms,
when a prgram or link is started.
EXT
λ
and
AUTOZERO
allow for external analog control of the photometer, if
the option ANALOG is choosen in the SETUP menu
die Option gewählt wurde, see section „CONTROL“ on
page 13.
Remote Socket
The remote socket on the rear side of the K–2600 UV detector serves
for sending and receiving start signals or error signals to or from other
instruments. For example an injection valve or an autosampler giving
start signals can be connected to the START IN input. All voltages have
to be mounted between GROUND and the corresponding output.
RS 232 Serial Interfaces
The two RS 232 serial interfaces on the rear side of the device, see
[5.4] in Fig. 3 on page 9, enable digital data transfer between the K–
2600 UV detector and compatible instruments such as pumps or a PC,
equipped with EuroChrom software. All the devices are communicating
with each other and form an integrated network.
