Mains
Connect phase to terminal (P), neutral to terminal (N), and earth to earthing ter-
minal.
Relays
There are four relays (REL1...REL4) with voltage-free contacts. Connect their
two contacts in series with the load. The ratings of the connected load should lie
between 12...250 VAC, maximum 1 A.
The measuring electrodes should be connected to the coaxial connectors CH1
or CH2. Automatic temperature compensation and measurement are possible by
connecting a Pt1000 thermocompensator to the coaxial connectors °C1 or °C2.
Without compensator, the manual temperature compensation is automatically
switched on.
•
Avoid ground loops by immersing an earthing rod in the process liquid close to
the electrodes. Connect it to terminal (MASS)!
•
Always cover the unused input connectors with the supplied protection
hoods!
Recorder
Two recorders (4-20 mA), one for each channel, can be connected to the (+) and
(-) terminals of (OUT1) and (OUT2). Max. impedance = 300 Ω.
RS485
Only use STP cable to connect up to 31 controllers to a computer!
