When the equipment is back in normal mode, the continuous blowdown valve returns to the control posi- tion. An intermittent blowdown pulse is also triggered (if automatic intermittent blowdown is enabled and a blowdown interval and blowdown time have been set).

Page 9: Usage For The Intended Purpose
Usage for the intended purpose The LRR 1-60 conductivity controller can be used together with the LRG 16-60, LRG 16-61 and LRG 17-60 conductivity electrodes as a conductivity controller in steam boilers and hot water installations, 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: Basic Safety Notes
Check that the plant is not carrying live voltage before commencing work. ■ Faulty equipment jeopardises plant safety. If the LRR 1-60 conductivity controller does not behave as described on pages 23 to ■ 24, it may be faulty. Perform failure analysis. -
Page 11: Function
Function The LRR 1-60 conductivity controller is a 3-point stepping controller. It cyclically evaluates the data tele- grams 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 with operating position function, and can actuate an intermittent blowdown valve. -

= power up/green = running/red = malfunction The MIN relay is configured as the MIN alarm on the URB 60 Startup During startup, all the relays of the LRR 1-60 3-point stepping conductivity controller are de-energised and the LED lights up orange. Normal operation During normal operation, when the supply voltage is on and the measured conductivity is within the MIN and MAX switchpoints, the MIN and MAX relays of the controller are energised. -
Page 24: The Min Relay Is Configured For Automatic Intermittent Blowdown On The Urb 60
In the event of a malfunction, the LED lights up red and the MIN/MAX relays become de-energised. The OPEN/CLOSED relays behave as described in the tables on page 24. Faulty equipment jeopardises plant safety. If the LRR 1-60 conductivity controller does not behave as described on this page, it may be ■ faulty. -
