A complete assembly the specific daylighting application. would consist of the control module and one of the • For each combination, calibration setpoints read following remotely mounted GE photodiode daylight out directly in footcandles. sensors: • Adjustable footcandle setpoints for both high- and low-trip to create a dead band. Indoor Sensor (RPSEN-IN) • Switch-enabled time-delay of 3 minutes. Outdoor Sensor (RPSEN-OUT) • Lockout switch for disabling the sensor. Atrium Sensor (RPSEN-ATR) • Three separate output channels, each capable of Skylight Sensor (RPSEN-SKY) driving up to three GE RR7 relays, or triggering the For normal installations, the sensor is wired to the input to an electronic switch (such as the RMSx control module with #20/4 ROSWIRE-4. Master Sequencer). • Master override of each channel. • Master control of all three channels. Before starting, read the Installation Instructions inside.

Reflectance of task surface… the fraction of light the OFF position. This will cause the control module which will be seen by the ceiling mounted sensor to respond immediately to changes in setting levels or compared to that measured at the workplane.

Example: 60 footcandles x 1.5 x know the target light level at the sensor, use Method 0.4 = 36 footcandles. Using the 10-100 RANGE on the A; if not, use Method B. RPCON, we would then set the LOW level scale at “4” and the HIGH level at “6”. (The HIGH level is normally Method A: Desired sensor light level known. set at least two ticks higher than the LOW level). The RPSEN-OUT, RPSEN-ATR and RPSEN-SKY: If you adjustment can be optimized upon installation. know the target light level for the sensor listed above, set the HIGH level at 1 tick higher than the target and Method B: Desired sensor light level not known. the LOW level at 1 tick less than the target. For This method can be used for all sensors, but it is example, if you wanted to set an atrium sensor at 400 typical for RPSEN-ATR and RPSEN-SKY sensors. This footcandles, the RANGE would be 100-1000, the HIGH approach requires that you wait until the time of day setting = 5, the LOW setting = 3.

The RPCON Automatic Response… Delay Enabled. This is the automatically pulses up to three lighting circuits in normal operating mode for a RPCON. The actions response to changes in natural daylight. The pulse is are the same as outlined above except that when the a 0.5 second dry contact closure compatibe with GE delay is enabled, the unit will wait 3 minutes after “RR” latching style relays or intelligent inputs. both LEDs come ON (or go OFF) to change the state of the relay. This reduces the possibility of short The RPCON has two setpoints… a high level and a duration fluctuations in light level (such as a cars low level. These dictate the ON/OFF operation of the headlights hitting an outdoor parking lot sensor) relay outputs in response to changing light levels. causing nuisane switching of the lighting circuits. The region between the high and low setting is referred to as a “dead band” because no relay Manual Override… Individual Output. Each of the actions will take place when the light level is in this three output channels is isolated allowing you to region. (The dead band eliminates the possibility of directly override the associated relay with a local low the controller going into an oscillating mode: the voltage switch (see the instructions provided with sensor sheds the lamps based on adequate lighting, your relay panel). Note, however, that this override is whereupon the new light level is so low that the not permanent. For example, if an individual uses his sensor activates the lamps ON again.) With the light local switch to turn a light back ON which the level below the dead band, both LEDs will be ON and daylight sensor has turned OFF, the next time the the relays will be ON.
