GESTRA LRGT 16-1 User Manual

10 LRR 1-52, LRR 1-53, URB 55 - Installation & Operating Manual - 850645-01
Usage for the intended purpose
LRR 1-52 and LRR 1-53 conductivity controllers can be used in combination with LRG 1x-x conductivity
electrodes and LRGT 1x-x conductivity transmitters as conductivity controllers and limiters in pressurised
steam and hot-water plants and in condensate and feedwater tanks. The conductivity controller indicates
when MAX or MIN conductivity has been reached, opens or closes a continuous blowdown valve and can
actuate an intermittent blowdown valve.
Configuration, operation and visual display
The equipment is configured and operated and information is viewed via the URB 50 or URB 55 visual
display and operating unit. The URB 55 is designed for installation in a control cabinet door or switch
panel. It may only be used when correctly installed. If you are using a URB 50, please pay attention to the
information in Installation & Operating Manual “LRR1-52-LRR1-53-URB50”.
