SC-100-CP
Basic Control System Clock
Operator’s Manual
Introduction
The SC-100-CP is an 8-channel time
clock designed for use in The Watt
Stopper Basic Control Contactor Panels.
The clock is used to program and
operate up to eight channels in a single
contactor panel, or across several
interconnected contactor panels. A
single clock in the main panel will signal
channels in all connected panels to
operate the lighting on or off. The clock
also enables programming of override
inputs in the main panel for additional
flexibility in controlling channels.
The SC-100-CP clock is pre-installed in
HINCP series interiors containing the
letter C in the catalog number just before
the suffix. Interiors with no clock have a
letter N in the catalog number. (Example:
HINCPxx16
C-115 or HINCPxx16N-115)
In multiple-panel installations, only one
main panel should be ordered with a
clock installed. Any expansion panels to
be interconnected with the main panel
cannot have a clock.
Features
• 365-day calendar time clock
• 4-line, 16-character display
• Controls up to 8 channels
• Enables and programs up to 8
override inputs
• Up to 120 event-based schedules
• Astronomic or photocell control for

Before Starting
Before using the SC-100-CP System
Clock, all panels should be installed,
wired to appropriate loads and override
devices, powered up and tested as
detailed in document INHINCP
Basic
Control Contactor Panel Interiors
Installation and Setup
.
The SC-100-CP clock is normally pre-
installed in HINCPxxxxC-115 interiors. If
adding the clock to an exisiting panel,
simply mount the clock on the mounting
studs in the upper left side of the interior
using the screws provided.
All power to the panel should be off
while installing the clock.
Next, plug the provided ribbon cable
from the clock into the 10-pin connector
labeled J9 on the circuit board.
Do not plug the clock into the circuit
board with power applied, or you may
cause damage to the circuit board.
Make sure mounting and connections
are secure, then re-apply power to the
panel.
In addition, the
Clock Channel Sched-
uling Worksheet
(see page 12), the
Holiday/Exception Dates Worksheet
(see page 13) and the
Override Input
Worksheet
(see page 14) should be
prepared, with a control strategy for each
channel defined and schedules outlined.
If documentation has not been prepared,
review Application Information on
pages 10 and 11 for guidance on how to
proceed.
Once control strategies have been
planned, follow the instructions on the
following pages to enter the necessary
information into the SC-100-CP clock.

Input Types
Inputs may be configured as one of four possible types:
• Momentary – Simple momentary pushbutton override.
Toggles the assigned channel(s) on or off, but does not
permanently override schedules. The next scheduled event
will take priority.
• Maintain – Maintained On/Off override. Contact closure
turns the channel on, contact open turns the channel off.
The next scheduled event will take priority.
• On/Auto – Contact closure forces the assigned channel(s) on,
keeping it/them on regardless of scheduled events. Contact
opening returns the channel(s) to its/their normally automated
state. This input type allows the user to select an override
duration of from 5 minutes to 11 hours, 55 minutes. Setting
this duration to 0:00 leaves the override on indefinitely (until
the contact opens).
• Photocell – Used when photocell input and schedules must
interlock. The schedule for an associated channel enables
the photocell to turn lighting on or off, but the photocell must
also indicate that it is dark or light enough to turn the
channel on or off.

Scheduling
Entering and maintaining correct schedules is the key to
operating the Basic Control Contactor Panel System most
efficiently. Care should be given to planning lighting groups
(channels) and their associated schedules in advance, so that
programming and operation are trouble-free. A
Clock Channel
Scheduling Worksheet
is included in the back of this manual
for schedule planning (see page 12).
Schedule Types
Menu Schedule Type Description:
Selection:
왘Time On Sends an ON command, turning the selected
clock channel on at the scheduled time and day.
왘Time Off Sends an OFF command, turning the selected
clock channel off at the scheduled time and day.
왘TmOn/Dawn* Used when a clock channel is to be turned on at
a scheduled time in the early morning, then
turned off at dawn (with an option to offset this
OFF event up to 2 hours before or after dawn).
왘Dusk/TmOf* Used when a clock channel is to be turned on at
dusk, then turned off at a scheduled time (with
an option to offset the ON event up to 2 hours
before or after dusk).
왘Dusk/Dawn* Used when a clock channel is to be turned on at
dusk and off at dawn (with an option to offset the
event up to 2 hours before or after dusk or dawn).
왘Stop Rept Stops a Repeating Schedule. Repeating Sched-
ules may include Time On, Time Off, AS Blink,
AS On or AS Off, if a Repeat interval is selected.
왘AS Blink Used when AS-110 Automatic Control Switches
are connected to a clock channel. Interrupts power
to the AS-110 switch for 1-2 seconds. This blinks
the lights and signals AS-110 switches to begin
a delay-off countdown.
왘AS On Signals connected AS-110 Automatic Control
Switches to turn their controlled lights on.
Interrupts power to the AS-110 switches for 3
seconds.
왘AS Off Signals connected AS-110 Automatic Control
Switches to turn their controlled lights off.
Interrupts power to the AS-110 switches for 5
seconds. (May also be used to signal existing
Sentry Switches to turn off).

Holidays
Up to 32 specific holidays or holiday date ranges may be
defined in the SC-100-CP clock. For each holiday, the user
selects one of three holiday schedules: H1, H2, or H3.
For example, H1 might be used for holidays such as Christmas,
when the building is closed all day. H2 might be used for an
alternate holiday schedule type, such as a half-day schedule.
H3 might be set up for other types of exception schedules,

SC-100-CP Basic Control System Clock — Operator’s Manual
Application Information
A detailed look at different control strategies required for specific
applications is included in The Watt Stopper Lighting Control
Panel binder, “Applications” Section 6. The following guidelines
are provided to show how certain common applications can be
implemented using Basic Control Contactor Panels and the
SC-100-CP clock.
In order to program the SC-100-CP clock to control lighting for
a specific application, questions to ask are:
What type of lighting is to be controlled: exterior or interior?
If exterior, is it photocell control or astronomical?
If photocell, is photocell installed on roof, facing north? Wired
to an input in the contactor panel?
Security or non-security lighting?
If interior, are AS-110 Automatic Control Switches installed?
Exterior Lighting
Different types of exterior lighting require different strategies.
Security lighting (exterior night lights)
These lights need to turn on whenever it is dark outside,
whether the building is occupied or not. The control strategy is:
• Dusk to Dawn
Non-security exterior lighting
This exterior lighting may include parking lot lighting and
signage. These lights need to operate when the building is
expected to be occupied, and it is dark outside. The control
strategy is to turn on at dusk and off at a scheduled time:
• Dusk On/Time Off, and sometimes also
• Time On/Dawn Off
An example of the second type would be an early shift arriving
when it is still dark, but once dawn arrives, lights need to turn
off.
The SC-100-CP clock provides several schedule types that are
typically used for exterior lighting. They are:
• Time On
• Time Off
• Dusk On/Dawn Off
• Dusk On/Time Off
• Time On/Dawn Off
These schedule types are implemented in conjunction with
either photocell input or astronomic control as detailed in the
table at the top of the facing page.
Overriding Clock Channels
The current state of the channels may be overridden at any
time by using the clock’s Override Channels function. These
overrides are temporary and will only last until the next
scheduled event for that channel.
From the Run Screen, press The Main Menu Screen appears,

Interior Lighting
For basic control, interior lighting is often simply scheduled on
and off. Using a contactor panel for interior lighting often
means less efficient control, since zones are relatively large.
However, used in conjunction with the AS-110 Automatic
Control Switch, contactor panels can provide cost-effective and
efficient control for certain types of interior spaces.
One typical example would be a building with a series of
peripheral offices. Using one circuit to feed all the offices is
cost-effective, but individual control in each office is needed.
The AS-110 Automatic Control Switch can provide a local
override in each office, while accepting signals from the panel
to control lighting automatically.
The SC-100-CP clock provides several schedule types that are
typically used for interior lighting. They are:
• Time On
• Time Off
• AS Blink
• AS On
• AS Off
• Stop Repeat (to set an end point for a repeating schedule)
Time On and Time Off are typical schedule entries for basic
lighting control.
The three “AS” schedule types refer to the AS-110 switch. This
switch will respond to a brief power interruption from the panel
as a control signal.
A one- to two-second interruption = AS Blink
Each switch will blink its own lighting and start a 5-minute
countdown before turning the lights off. Any occupant pressing
the switch during this time will override the lights on until the
next scheduled or repeated AS Blink occurs.
A three-second interruption = AS On
The switch will turn its associated lighting on after this signal
from the panel, typically used in a common area such as a
lobby, or a small manufacturing area with a rigid schedule.
AS-110 Automatic Control Switches must be configured in
setup to respond to an AS On schedule type.
A five-second interruption = AS Off
The lighting will turn off immediately, with no blink warning
interval, and is used for applications such as HID lighting, or
retrofitting a Sentry Switch.
When scheduled to repeat, all three AS schedule types will
provide the specified power interruptions at regular intervals
until stopped by the Stop Repeat schedule type.
Example Schedule:
Interior Lighting – Peripheral offices with AS-110 switches
1st entry:
6 p.m. Monday–Friday, AS Blink, Repeat signal every 2 hours
2nd entry:
6 a.m. Monday–Friday, Stop Repeat
This simple two-step entry will meet the control requirements
for the individual office areas for the whole week, including
weekends. The AS Blink signal will continue to repeat through-
out the weekends or on any holidays not covered by another
schedule.
