LED INDICATORS:
PWR (Power)
The green LED illuminates when 24 volts DC is supplied to the CNCS.
FULL LOAD
The red LED illuminates when FULL LOAD threshold has been exceeded.
PARTIAL LOAD
The yellow LED illuminates when PARTIAL LOAD threshold has been exceeded.
USER ADJUSTMENTS:
FULL LOAD Threshold
Clockwise (CW) rotation of the 15-turn POT increases threshold (i.e., reduces sensitivity) and changes
partial load threshold, accordingly.
partial load threshold, accordingly.
PARTIAL LOAD Threshold
Clockwise rotation of the 15-turn POT increases threshold (i.e., reduces sensitivity).
THRESHOLD ADJUSTMENTS:
Refer to figure 2 for a block diagram illustrating hookup connections for the CNCS.
NOTES
1.
Do not attempt adjustments during periods of high or low power line voltage or
voltage fluctuations.

2.
Partial power output may be used as the primary output if increased sensitivity is
required.

3.
If the partial power output is not required, the partial power adjustment may be
placed in any position which does not cause LED flashing or relay chatter.
