Installation Instructions

HPCP8SS

Photocell Control Module for Lighting Integrator

Installation and Setup

The Photocell Control Module is a dataline device

for outdoor lighting control. The package includes a

controller that connects to a relay panel in a Lighting

Integrator system and an external Photocell Sensor.

The 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 Lighting Integrator system. The Controller

interacts with either the HCLK8SS Network Clock

or the HBMS8SS BMS Interface Module, or the

AA-BASE Automation Appliance, one of which must

be present in the system. Set points for each channel

are programmed at the Clock, BMS Module, or

the AA-BASE. 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 Lighting Integrator Installation

Manual and the installation manual that came with

the Clock or BMS Module.

Note: These installation instructions assume that at

least one Lighting Integrator lighting control panel is

already installed, and that a Network Clock (HCLK8SS),

Building Management System Interface Module

(HBMS8SS), or AA-BASE Automation Appliance is

already connected to the system.

INSTALL THE SENSOR

You can install the Photocell Sensor

before or after 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.

Connect the HPSA Photocell Sensor

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 Lighting Integrator panel. (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:

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. Scenarios assigned

to each channel are documented on

either the Network Clock Automation

Scenarios form, or the BMS Interface

Automation Scenarios form. 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 the Lighting Integrator Installation

manual section called “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

two interior scenarios only:

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

CAUTION

Once programming complete, do not disconnect the

control module from the system.

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 Installation and Setup).

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 (STWX) 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 footcandle 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.

Example 2: Channel B – Dark ON/Sched 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 (STWX) 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.

Time Spanning – Setting Occupied/Unoccupied Times

For Late Night Hours (also see the HCLK manual)

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 Photocontrol Control Module — Installation and Setup

TEST 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.

Simulated Light

Level: = 009 fc

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

Installation Instructions).

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.

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.

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:

Measured Light-

Level: = 200+(fc)

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.

A set at 008(fc)

Level: = 200+(fc)

Repeat this check for all channels.

Channels not programmed with

daylighting scenarios will show – – – (fc).

H set at ---(fc)

Level: = 200+(fc)

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.

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.

HPCP8SS Photocontrol Control Module — Installation and Setup

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

Photocell Control Module doesn’t

display any light level set for it.

Check that the current day and time

set in the Clock is consistent with the

programmed days and times. 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

Unoccupied, 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.
