Photocell Test (Ph)
This Setup mode is used to test photocell output.
NOTE: Auto-Discovery must be performed before the CLS-C6 recognizes a
GLS-LOL photocell. The photocell must also be installed and wired to a GLS-SIM
or C2N-CBD-P Keypad.
To test photocell output:
Enter Setup mode and scroll to the "Ph" option (using the ^ and v buttons).
•
Press and hold either the top or bottom portion of the raise/lower button.
The 2-digit display indicates the real-time output of the photocell in a
percentage (0 to 99).
• Press the Cancel button to return to Standard mode.
NOTE: When in "Ph" mode, daylight harvesting shall be disabled.
Photocell Calibration (Pc)
This Setup mode is used to calibrate the photocell response when Daylight
Harvesting is enabled. Photocell calibration is required to customize the lighting
response to changes in daylight. The CLS-C6 allows each load to be calibrated
independently for maximum performance. Typically, loads that are closest to sources
of natural light are made more sensitive to daylight, and those that are furthest from
daylight are made less sensitive. Loads that receive little or no daylight can be
disregarded by the photocell.
NOTE: Photocell calibration is best performed on a sunny day, when all loads are
above their minimum dim level, but below 80%. Performing photocell calibration
when there is insufficient daylight may cause undesired operation on a bright day.
Conversely, performing photocell calibration when there is excessive daylight may
prematurely trigger loads to reach their minimum dim level (refer to "Photocell
Lower Limit (PL)", on the following page), making calibration impossible.
NOTE: Loads configured with high sensitivity change more in response to changes
in daylight. On a bright day, these loads are lower. Loads configured with low
sensitivity respond less to changes in daylight. On a bright day, these loads are
higher.
NOTE: Internal scene levels for all loads increase to 100% for calibration purposes
while in this mode.
NOTE: Non-dim loads cannot be used with Daylight Harvesting.
To calibrate a photocell:
Enter Setup mode and scroll to the "PC" option (using the ^ and v buttons).
•
Press either the top or bottom portion of the raise/lower button. A period
appears in the 2-digit display, indicating the mode has been selected.
• If a photocell is present, Scenes 1 through 8 (plus the ON scene) are
automatically under photocell control. Scenes 9 through 16 ignore the
photocell at all times.
• To enable/disable photocell control for a given load, press and hold both
sides of its rocker button for 5 seconds. Loads that are not controlled by a
photocell display a bar graph with only the top two and bottom two LEDs
lit.
