2.5 Connecting electrical signal cables
The sockets for electrical signals are located on the rear panel.
Connecting to chart recorder (if used)
The external chart recorder outputs for pH and conductivity from
the monitor are 0 – 1 V. There is also a 4 – 20 mA signal available
at the same output connectors.
1 Connect the chart recorder to the DIN-socket pH or Cond using
the cable supplied:
a. For 0 - 1 V use wire 1 (+) and 2 (–). Use a recorder with
floating inputs (i.e. none of the inputs connected to ground).
b. For 4 - 20 mA use wire 5 (+) and wire 6 (–).
Note: The signal cable is delivered with protective covers on each
wire. Do not remove the protective covers from unused
connections as a short circuit may disturb the measurements.
2 Set the recorder to 0–1 V or 4 - 20 mA input, full scale.
2.6 Connecting to communication link
The monitor can be used in ÄKTAexplorer and ÄKTApurifier, and
can be controlled from a PC running UNICORN™ version 2.20 or
higher, using UniNet cables.
Connect two UniNet cables to the UniNet 1 connectors. The
instrument can be connected in series anywhere between the PC and
a termination plug. The UniNet 1 link connects, in series, the PC
with Pump P-900, Monitor pH/C-900, Monitor UV-900 and the
Frac-900. The termination plug is connected to the last instrument in
the chain.
