Programming Photocells
Photocells are essentially switches that trigger at certain
light levels. They may be programmed by selecting the pho-
tocell card from a list of switches.
Pressing ENTER takes you to a list of "Triggers." Each trig-
ger is like a switch button in that when the light point is
made it issues the same commands as a switch would. The
only difference is that a single photocell can issue up to 14
triggers at different light levels.
This may seem like an excessive amount of triggers but it
does allow some very tricky daylight harvesting scenarios.
On three input cards the 14 triggers are divided amongst
the 3 Analog (Photocell) inputs and the three enable inputs
plus one additional contact closure input which is not usual-
ly mounted on the control card.
Pressing Enter on a Trigger gets to the typical switch load
listing page. Fill in the loads that this trigger will control.
Scroll to MAINTAIN and press ENTER.

Notice that the direction of increase/ decrease is relevant.
Rising through the ON level does not trigger. Only falling
through it. The opposite is true of the OFF level.
Set the ON and OFF levels for your application. The current
reading of the sensor is shown on the bottom line. The
reading is approximately equivalent to foot candles and has
the same sensitivity as the human eye.
Time delay may be set from 1 to 30 mins or to 5 seconds
for testing.
On a 3 input card "ANALOG 1" may be scrolled through the
three analog inputs and 4 digital inputs to choose what is
doing the triggering. A Digital (Dry contact switch) does not
need trigger levels set.
Highlighting the current reading of light level and pressing
enter allows you to select the current sensor to be displayed
on the opening page of the Clock display.
