Bringing into service – start, operation and alarm
Fig. 9
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. The LED lights up green.
Alarm
If the conductivity value is below the set MIN limit or above the set MAX limit, the appropriate relay (MIN/
MAX) of the controller is de-energised and indicates that MIN/MAX conductivity has been reached. The
LED lights up green.
The output relays (CLOSED/OPEN) of the LRR 1-60 3-point stepping conductivity controller that actuate
the BAE continuous blowdown valve are energised or de-energised, as required.
