Before Installation
IMPORTANT
Expose the photocell to light for 16 hours.
The photocells develop a hysteresis (or "light memory") when
packed for shipping. Until the photocell has been exposed to
bright light for at least 16 hours, light level setpoints will shift.
Location
Locate the cadmium sulfide photocell sensor C7057A1000
(supplied with this controller) so that the lens is exposed to full
daylight. (See Fig. 2.)
NOTES:
—
Select an area which will not become shaded.
—
Mount only with light entrance facing horizontally.
—
Avoid overexposure to direct east/west sunlight.
