Step 5:
In a closed loop configuration, move the Auto-Cal switch to the ON
position as shown in the manual to activate.
Note:
This feature operates the luminaires at full output for a period of 24 hours.
During this time, the miniZ will record the lowest foot-candle reading from the photocell
and record that value as the target illumination. The target illumination is the level that
the miniZ will maintain with the load control output as daylight is available to the
space. The lights will automatically raise or lower (dimmed models) based on how
much daylight is contributing to the overall foot-candle value present to the photocell.
Step 7:
Adjust the proportional dimming output (dimmed models only). The miniZ
has proportional dimming using only one photocell input. To optimize the
light level balance in the space, adjustment to the daylight harvesting
threshold trim pots may be necessary.
For a 2 zone application:
• The zone closest to the daylight source (zone 1) should be turned to 10 or full
clockwise. The next zone (zone 2) should be adjusted to 4 on the dial. This will
balance the dimming so that the light level across the space is more uniform.
For a 3 zone application:
• The trim pots should be zone 1 = 10, zone 2 = 7 and zone 3 = 3.
Step 6:
If the fluorescent lamps are new, move the Burn-In switch to the ON
position as shown in the manual to activate the 100 hour Burn-In feature.
This will keep the lamps from dimming until 100 hours of operating time.
After that they will operate in the dimmed mode.
Note:
Both the Auto-Cal and the Burn-In can occur at the same time.
