Page 3: Introducton
Overview The DLC-PDC Photodiode Controller automatically switches a dry contact in response to change in natural daylight. The DLC-PDC provides a maintained single pole, double-throw relay output to drive electrically held contactors or relays, or has the ability to provide inputs to Energy Management Systems (EMS). -
Page 4: Installation
INSTALLATION The DLC-PDC controller can be mounted anywhere that 15VDC can be provided, and with a wiring distance within 500’ of the DLC-PD sensor. The sensor should be mounted per its Installation and Maintenance Manual. Power Connections The DLC-PDC 15VDC power should be connected to Terminal 5 at the bottom of the controller board;... -
Page 5: Operation
The top trimpot labeled “OFF” (see Figure 2) sets the High Level Setpoint which is the level commonly set for dawn. As the sun rises, the DLC-PDC will switch on both the relay and upper LED signifying that the lighting will be switched off. This setup is typical for most applications. Note that while the daylight is increasing the Low Level LED will illuminate, but this will be disregarded by the controller. -
Page 6: Low Level Setpoint And Led Indicator
Therefore as described above if the LED is lit the lighting connected to the DLC-PDC is off in typical dusk to dawn applications and if the LED is off the lighting connected to the DLC-PDC is on in typical dusk to dawn applications. -
Page 7: Sequence Of Operation
Sequence of Operation The DLC-PDC operating sequence will be described below referencing Figure 3. 1. At dawn the sensed light level increases approaching the High Level Setpoint through the Low Level Setpoint, the Low Level Setpoint LED will switch ON, while the High Level Setpoint LED remains OFF. -
Page 8: Calibration
This procedure has been created in such a manner as to not require any sophisticated calibration equipment. Shown below are the tools needed for Dusk-To-Dawn calibration of the DLC-PDC. SMALL FLATHEAD SCREWDRIVER 1/8”... -
Page 9: Footcandle Settings Guide
Footcandle Settings Guide The DLC-PDC has a placard attached to the front of the controller which can be used as a reference guide for a DLC-PD-IN sensor, which is the most common application. Included below is an expanded guide for the DLC-PD sensors. -
