3.2.1  Switching on the LIQ-60

 

The  LIQ-

60’s  power switch is located on the  bottom  panel.  It  is a  rotating  switch that turns  through  90 

degrees between the OFF and ON positions, as indicated by  arrows. 

•

 

Rotate the switch clockwise to the ON position. In the ON position it will be in line with the 2 (red) 
fault indicating LEDs. 

•

 

When the unit is powered on the red and amber 

LED’s will start a flash sequence. The red LED 

will flash 8 times followed by 8 flashes from the amber LED. 

•

 

After the start up sequence, the red LEDs will illuminate once every second indicating that t h e  unit 
is  in  a  non-sensing  state,  awaiting  commissioning.  Prior  to  commissioning  the  amber  LED will 
flash 3 times every 30 seconds. If after one hour the LIQ-60 has not been manually commissioned, 
it will commission itself automatically. 

Refer to Table 1 on page 17 for an explanation of LED status and fault indication  sequences. 

 

4  Configuration

 

Before  the  LIQ-Gateway  and  LIQ-60s  are  mounted  and  commissioned,  they  need  to  be  configured. 
Configuration of the LIQ-60 and the LIQ-Gateway is performed using LineMan and an  LIQ-LocalLink. 

 

4.1  LIQ-60 configuration

 

The LIQ-60 is configured using LineMan software. 

Please refer to Appendix A for instruction on configuring the LIQ-60 with the LineMan software. 
Commissioning 

LIQ-60s must be commissioned after  configuration. 

 

5  Commissioning

 

 

5.1  Commissioning the LIQ-60

 

If  the  LIQ-60  is  intended  to  operate 

“stand  alone”,  without  an  associated  LIQ-Gateway,  it  needs  to  be 

commissioned directly using a laptop PC and an LIQ-LocalLink local-RF radio, with the LineMan software 
interface. If the LIQ-60 is associated  with an LIQ-Gateway, the LIQ-60 is then commissioned via the LIQ-
Gateway. 

 

5.1.1  Pre-commissioning check of the LIQ-60s

 

Using a laptop running LineMan, connect to each LIQ-60. 

Confirm that: 

•

 

The internal battery voltage exceeds 2V. 

•

 

There is some solar charge current when the solar panel is illuminated. 

•

 

Event recording is enabled if required. 

•

 

Load logging is enabled if required. 

•

 

Line currents are as expected. 

•

 

Voltage sensor values are as expected.
