Page 9: Usage For The Intended Purpose
Usage for the intended purpose The LRR 1-60 conductivity controller can be used in conjunction with LRG 16-60, LRG 16-61 and LRG 17- 60 conductivity electrodes as a conductivity controller 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. -
Page 10: Applicable Directives And Standards
Usage for the intended purpose Applicable directives and standards The LRR 1-60 conductivity controller has been tested and approved for use in the scope governed by the following directives and standards: Directives: Directive 2014/35/EU Low Voltage Directive ■ ■ Directive 2014/30/EU EMC Directive ■... -

Page 12: Function
Function The LRR 1-60 conductivity controller is a 3-point stepping controller. It periodically evaluates the data telegrams from a conductivity electrode (e.g. LRG 16-60, LRG 16-61 or LRG 17-60). 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. -
