Relay settings:
The relay output modes of operation is switchable via DIP switch 6 at the back side (see chapter
Back side settings and terminal connections).
DIP switch position off (bottom):
Relays drop at limit value exceedance
DIP switch position on (top): Relays are triggered at limit value exceedance
K1 Manual control of relay 1 (The buttons for the relay control invert the respective
switching state for the actuation time.)
K2 Manual control of relay 2 (The buttons for the relay control invert the respective
switching state for the actuation time.)
Limit value settings:
Push buttons F1, G1 and G2 simultaneously for 3
sec. As a result the programming mode is active and
LED F1 flashes.
Push buttons F1 and G1 simultaneously, then
limit value 1 can be changed.
Push buttons F1 and G2 simultaneously, then
limit value 2 can be changed.
Approx. 5 seconds after the last activation both limit values are being saved and the adjustment
mode will be locked.
Both limit values can be adjusted to any value between 0 % and 100 % of the measuring range.
Calibration:
Zero point and measuring range of the instrument are pre-calibrated. A correction is normally not
necessary.

Measur. range 0 – 200 without TC on off off on on ** K = 0.1
Measur. range 0 – 2000 with TC on off on on off ** K = 1.0, Pt100
Measur. range 0 – 2000 without TC on off on on on ** K = 1.0
For DIP switch position S5: ** For DIP switch position S6:
With Temp. compensation: bottom Relay triggered at conductivity < limit value: on
Without Temp. compensation: top Relay triggered at conductivity > limit value: off
Only one power supply connection is permitted; either 230 V AC or 24 V DC. The 24 V DC input
is protected against voltage reversal. AC voltage at the 24 V DC input oder DC voltage at the
230 V AC input destroy the instrument immediately and completely.
The measuring cell connection cable must be a shielded type for usage in industrial
environments at lengths above 1 meter.
The terminals ground and shield are internally connected to the common housing ground
(Voltage isolation of 1000 V to the power transformer and to the 24 V DC connection,
respectively). Under no circumstances these terminals should be bridged to another terminal
or connected to an existing ground connection. Otherwise the potential isolation of
measuring cell and electronics will be overruled.
6. Further operating conditions
The operation of the measuring instrument above the permitted measuring range and constant
short-circuit, respectively, can lead to instrument damage!
