Safety function
– version UB / UC with relay output
The safety function defines the operation principle of the relays.
Maximum safety:
The relay switches off, if the switching level is transgressed,
(liquid connection between measuring and reference electrode REF)
or the power supply fails.
Minimum safety:
The relay switches off, if the switching level is underrun,
(no liquid connection between measuring and reference electrode REF)
or the power supply fails.
For both channels, CH1 and CH2, the safety function can be set separately.
This can be carried out by two jumper, one per channel, inside the housing of the device.
Two-position-control
s (pump control)
– version UB / UC with relay output
The activation of the two-position-control for the output relay S1 is made by a switch inside the device.
The output relay S2* continues operation in limit value mode.
Two-position-control
– minimum safety
Two-position-control
– maximum safety
* The relay S2 is only available at the version UC (wide range power supply with 2x relay output)
