Photocell Control Module

Installation and Setup

The HPCU8SS Photocell Control Module is a

dataline device for outdoor lighting control.

It must be used in conjunction with the HPSA

Photocell Sensor, and connects to any relay

panel in a Smartwired Switching System. The

HPCP8SS is a package combining both the

controller and the sensor.

The HPCU8SS Photocell Controller compares the

actual outdoor light level with the set point

selected by the user for each of up to 8 channels,

or lighting groups, in a Smartwired Switching

System. The Controller interacts with either the

HCLK8SS Network Clock or the HBMS8SS BMS

Interface Module, one of which must be present

in the system. Set points for each channel are

programmed at the Clock or BMS Module. The

Clock or BMS Module provides scheduling,

occupancy information and the smart scenarios

that tell the relay panels how to respond to a

“Dark” or “Not Dark” signal from the HPCU8SS

Photocell Controller.

Features:

• Tracks “Dark/Not Dark” state for each of 8

channels in the system

• Real time LCD display of actual exterior

light level up to 200 footcandles

• Choice of “Operate” or “Test” modes to

simplify setup

• Automatic deadband and 5-minute time

delay avoid nuisance switching

• Bi-color LED indicates “Dark/Not Dark”

state for each channel

• Integrates automatically with Network

Clock or BMS Interface Module

Before proceeding, read the instructions on

the following pages. Please refer to the

project documentation in the SMARTWIRED

SWITCHING SYSTEM INSTALLATION AND

OPERATION MANUAL that came with the

Clock or BMS Module. If you have questions,

call our Service Team at: 888-852-2778.

These installation instructions assume that at

least one Smartwired Lighting Control Panel

is already installed, and that a Network Clock

(HCLK8SS) or Building Management System

Interface Module (HBMS8SS) is already

connected to the system.

Basic Installation Steps

1 Install the HPSA Sensor on the roof

2 Connect the HCPU8SS Photocell

Control Module to the dataline

3 Program the channels that will use

daylighting scenarios using the Clock

or BMS module

4 Conﬁrm that the HPCU8SS has received

data

5 Test the operation of the system

Install The Photocell Sensor

(You can install the Photocell Sensor last,

but wire it to the HCPU8SS Module for

initial testing as described on page 6).

Mount the HPSA Photocell Sensor on the

outside of a weathertight junction box on

the building roof, facing toward the

northern sky as illustrated in Figure 1.

Make sure the sensor lens is not subject

to shadows or directly aimed at a light

source. In areas subject to snow, the

sensor must be mounted 12 inches above

the snow line.

Wire back to the relay panel where the

HCPU8SS Control Module will be mounted

using 3-conductor 20 AWG wire.

Install The Control Module

Refer to the callouts shown to the right.

The HPCU8SS snaps onto the DIN rail in

any Smartwired relay panel. (There is a

release clip on the bottom of the unit.)

Connect the wiring from the Photocell

Sensor to the photocell input terminals

labeled R/B/W. If using shielded cable,

which is not required, terminate the

shield at the terminal labeled S.

Plug the supplied cable into the dataline

connection at the bottom of the unit.

Then plug the cable into one of the Local

Dataline connectors in any panel.

The HCPU8SS Module will display the

Main screen as shown below:

The eight channel LED indicators on the

face of the Module should all be off.

Program The Channels

Lighting groups with similar control

functions, such as exterior security

lighting, must be smartwired to the

appropriate channels (A-H) in the system.

Relays assigned to each channel are

documented on each panel’s Relay

Schedule form (HID-SSREL). Scenarios

assigned to each channel are documented

on either the Network Clock Automation

Scenarios form (HID-SSCLK), or the

BMS Interface Automation Scenarios

form (HID-SSBMS). Sample forms are

shown below.

Note that only one Network clock or

BMS Interface Module may be connected

to the network at one time.

Determine which channels will use the

daylighting scenarios. Make sure the

appropriate relays in each panel are

Smartwired to the correct channels. See

Smartwired Switching System Interior

Installation and Setup, (document

INHINSS) page 3, “Smartwiring a Relay

Group to a Channel”.

Program each Channel using the Network

Clock or BMS Interface Module as detailed

on the following pages.

Smart Scenarios

With no Photocell Control Module in the

system, the Network Clock offers four

possible scenarios for operating channels,

or lighting groups — two for interior

lighting and two for exterior lighting. The

BMS Interface Module offers the two

interior scenarios only.

The scenarios are:

Interior Lighting:

• Manual ON / Scheduled OFF

• Scheduled ON/OFF

Exterior Lighting:

• Astro ON/OFF

• Astro ON / Scheduled OFF

The Astro scenarios provide an astronomical

timeclock function — or an approximation

of the level of darkness based on the

site’s location — when the Clock is

programmed with location information.

When a Photocell Control Module is added

to the system, the Clock automatically

detects its presence and changes the

exterior lighting scenarios from Astro to

“Dark.” The BMS Interface also detects

the presence of the Control Module and

adds the two daylighting scenarios.

Available scenarios for both the Clock

and BMS Interface Module now read:

Interior Lighting:

• Manual ON / Scheduled OFF

• Scheduled ON/OFF

Exterior Lighting:

• Dark ON/OFF

• Dark ON / Scheduled OFF

Programming Daylight Scenarios

Using the Network Clock

Both the HCLK8SS Network Clock and the HPCU8SS Photocell

Control Module must be connected to the network via the

Local Dataline connection in any of the panels. (For more detail

on how to program scenarios using the Network Clock, refer to

instructions Network Clock – Scheduling Mode Installation

and Setup, (document INHCLK-S).

Clock Example 1: Channel A – Dark ON/OFF

A At the Clock’s main Channel Status screen, advance to

Program, if necessary, using the cursor keys ( )

and press SELECT (Figure 2).

B In the Channel scheduling screen (Figure 3), SELECT

Channel A, then advance to the next ﬁeld and use the RAISE

or LOWER key to toggle through the available scenarios until

you reach Dark ON/OFF. Press SELECT. The screen shown

in Figure 4 will appear.

C The ﬂashing cursor will prompt for a darkness level to be

set. Use the RAISE or LOWER key to increase or decrease

the footcandle level in increments of 2 fc up to 200 fc.

Recommended footcande levels are:

Security and parking = 6 fc, signage = 40 fc.

D When the desired level is set, advance to SAVE and press

SELECT. The Clock will return to the main Channel Status

screen shown in Figure 2.

Clock Example 2: Channel B – Dark ON / Scheduled OFF

A At the Clock’s main Channel Status screen, SELECT

Program, as shown above in step A and Figure 2.

B In the Channel scheduling screen as shown in Figure 3,

SELECT Channel B, then advance to the next ﬁeld and use

the RAISE or LOWER key to toggle through the available

scenarios until you reach Dark ON / Sched OFF. Press

SELECT. The screen shown in Figure 5 will appear.

C Use the cursor keys ( ) and SELECT key to move

from ﬁeld to ﬁeld, and the RAISE or LOWER key to change

values. Choose the Day of the week and enter that day’s

Open (“Occupied”) times. The example shown in Figure 5

is 6 a.m. until 9 p.m.

D Advance to the next ﬁeld and the ﬂashing cursor will prompt

for a darkness level to be set. Use the RAISE or LOWER key

to increase or decrease the footcandle level in increments of

2 fc up to 200 fc.

E Setting the footcandle level to – – – means no level is

selected, so the scenario will not function. This option

allows you to clear out previous programming.

F When the desired level is set, advance to SAVE — or COPY

this schedule to another day(s) — then press SELECT. The

Clock will return to the main Channel Status screen.

Example: A restaurant needs parking lot lighting to be Unoccupied

only from 1:00 a.m. to 6:00 a.m. Parking lot lighting will turn off

after 1:00 a.m. (and dark), then on again, if still dark, at 6:00 a.m.

when the channel goes Occupied, then off again at daylight.

HPCP8SS Photocell Control Module — Installation and Setup

Test The System Operation

• Move the TEST/OPERATE switch on

the left side of the Control Module to

the TEST position. The screen will

now display a Simulated Light Level,

rather than actual light level.

• Using the UP or DOWN key, change

the Simulated Light Level to 000.

The channel LEDs for those channels

you’ve programmed for daylighting

scenarios (A and B in our example)

will be lit red. The LED color indicates

how the actual or simulated light level

compares to the channel’s programmed

set point:

Red = The actual (or simulated) light

level is less than the light level

setting for that channel. Therefore,

the relay(s) associated with that

channel should be on if the input

contact indicates Occupied.

Green = The actual (or simulated)

light level is greater than the light

level setting for that channel. The

relay(s) associated with that channel

should be off if the input contact

indicates Occupied.

Off = An unlit LED indicates there is

no light level set for that channel.

• Check the time on the Network Clock,

or the occupancy status of the channel

input to the BMS Interface Module. If it

is not within an Occupied period, reset

the Clock or BMS Module input to an

Occupied time. For the Clock, use the

Setup screen (see the Network Clock

– Scheduling Mode Installation and

Setup instructions, page 6).

• Use the UP key on the Control Module

to raise the simulated light level. As the

light level passes the lowest footcandle

setting for a channel, that channel’s

LED will change from red to green,

and that channel’s relay(s) will turn off.

Continue to raise the light level until it

exceeds all channel set points, and all

relays have turned off.

Conﬁrm That The Control

Module Has Received Data

Check the Control Module’s display

screen. It should register the Measured

Light Level outdoors. If it is daylight, the

screen will appear as shown:

Pressing a channel button on the face of

the Control Module will display the light

level set for that channel, compared to

the measured light level outdoors.

Releasing the button returns the screen to

the standard Measured Light Level.

Repeat this check for all channels. Channels

not programmed with daylighting scenarios

will show – – – (fc):

Simulated Light

Level: = 009 fc

Measured Light–

Level: = 200+(fc)

A set at 008(fc)

Level: = 200+(fc)

H set at ---(fc)

Level: = 200+(fc)

• Reverse the previous test, using the

DOWN key to decrease the simulated

light level. As the light level passes each

channel’s set point, that channel’s LED

should turn red, and relay(s) should

turn on. When the simulated light level

reaches 000 fc, all channels with

daylighting scenarios should be red.

• Set the time on the Clock, or the input

to the BMS Interface Module to an

Unoccupied period and repeat the test

above. First increase the simulated light

level past all channel set points, then

decrease back to 000. Depending on

the channel’s scenario, the LEDs and

relays will respond differently:

Dark ON/OFF channels will reﬂect the

state of the LED on the Control Module:

Red LED = light level is lower than the

set point – relays turn on; Green LED =

light level is higher than the set point –

relays turn off.

Dark ON / Scheduled OFF channels

will leave relays off, even when the

channel LED changes state, because

the building is Unoccupied.

Reset To OPERATE Mode

Reset the Network Clock to the correct

time, or make sure the inputs to the BMS

Interface Module’s channels are connected

and operational. Move the Control

Module’s TEST/OPERATE switch back to

OPERATE.

HPCP8SS Photocell Control Module — Installation and Setup

Deadband

In the OPERATE mode, the Control Module

uses a deadband of 6 footcandles and a

5-minute time delay to avoid nuisance

switching. As light levels increase, there is a

deadband of 6 fc above the actual set point

before the Control Module will signal

“Dark.” As light levels decrease, the actual

light level and set point are equal. In either

case, the actual measured light level must

remain at the trigger point for 5 continuous

minutes before the Control Module will

send a “Dark” signal.

Example 1: A channel’s set point is 20 fc.

As light levels increase, the channel LED

will turn green (signaling “Not Dark”)

after ﬁve minutes at or above 26 fc. As

light levels decrease, the channel LED

will turn red (signalling “Dark”) after ﬁve

minutes at or below 20 fc.

Example 2: A channel’s set point is 10 fc.

The measured light level is at 14 fc. No

change will occur until the light level

rises to 16 fc and stays there for ﬁve

continuous minutes.

Troubleshooting

I unplugged the Photocell Control Module

and now all my programming is gone.

Do not disconnect the Photocell Control

Module from the system once programming

is complete. Disconnecting the Control

Module tells the Clock or BMS Interface

Module that the Photocell is not present,

so “Dark” scenarios can no longer function.

To avoid conﬂicts, the Network Clock or

BMS Interface Module will not save the

previously programmed scenarios for

those channels using Dark ON or Dark

ON / Scheduled OFF. If the Control Module

is disconnected and then reconnected,

programming for those channels using

daylighting scenarios must be re-entered.

It is permissible to disconnect the Network

Clock (or BMS Interface Module) from

the system ﬁrst, to use the Clock as a

Switch Programmer, for example. The

Clock or BMS Module will retain the

daylighting scenarios as long as the

Photocell Control Module is connected to

the system when the Clock/BMS is

plugged back into the Local Dataline.

I programmed a channel but the Photo-

cell Control Module doesn’t display any

light level set for it.

Check that the current time and day set

in the Clock is consistent with the

programmed times and days. Make sure

that the program is copied to every day

of the week where Dark ON / Scheduled

OFF is the desired scenario.

The channel is programmed and the

correct set point displays on the Photocell

Control Module, but nothing happens

when the actual light level goes past the

set point.

Conﬁrm that the actual day and time

currently set in the Clock falls within a

time that is scheduled as Occupied. If the

scenario is Dark On / Scheduled Off, and

the Clock or BMS Module says Unoccu-

pied, then lighting should not respond to

a change in outdoor light levels.

Also conﬁrm that the actual light level

has been at least 6 footcandles above the

set point for ﬁve continuous minutes. If

not, the deadband and time delay may be

in effect (see Example 2 in the previous

section). To eliminate this possibility,

move the Photocell Control Module’s

TEST/OPERATE switch to TEST, which

will disable the deadband and time delay,

and check again.
