Conductivity controllers can be combined in a circuit with conductivity electrodes or transmitters as follows: LRR 1-50 conductivity controller with LRG 12-2, LRG 16-4, LRG 16-9, LRG 17-1 and LRG 19-1 conductivity electrodes; LRR 1-51 conductivity controller with LRGT 16-1, LRGT 16-2, LRGT 16-3, LRGT 16-4, LRGT 17-3 and LRGT 17-1 conductivity transmitters.
MAX alarm is triggered and the continuous blowdown valve moves into OPERATING position. If malfunctions occur only in the LRR 1-50, LRR 1-51 conductivity controller, the MAX alarm is trig- gered, the continuous blowdown valve moves into OPERATING position and the equipment is restarted.
The name plate indicates the technical features of the equipment. Do not bring into ser- vice or operate any equipment that does not bear its own specific name plate. LRR 1-50, LRR 1-51 - Installation & Operating Manual - 819224-05...
VdTÜV Bulletin “Wasserüberwachung 100” (Water Monitoring 100) The LRR 1-50, LRR 1-51 conductivity controller, in combination with the LRG 1.-.. conductivity elec- trode and LRGT 1.-.. conductivity transmitter, has type approval in accordance with VdTÜV Bulletin “Wasserüberwachung 100”. The VdTÜV Bulletin “Wasserüberwachung 100” describes the require- ments for water monitoring equipment.
