Occupancy Sensor Disabled /
Emergency Input
A
Label: OCC DISABLE / EMERGENCY
Set by DIP Switch: Block 1 Number 1
This is a +24V input signal. Function can be set to
either mode exclusively.
Occupancy Disable Mode
When the input goes high (+24V) the Power Pack
will disable the Occupancy Sensor input and there
will be no change in the current state. When the
input signal is removed, the Occupancy Sensor will
return to the normal mode.
Emergency Mode
Emergency mode is triggered when the emergency
input is connected to the common. When the signal
is received, the Power Pack will turn on all zones
by turning on all relays and raising any 0 – 10V
outputs to 10 V. The Power Pack zones will remain
fully illuminated until the Emergency signal is
removed.
Photocell Disable / Force Off Input
Label: PC DISABLE / FORCE OFF
Set by DIP Switch: Block 1 Number 2
This is a +24V input signal. Function can be set to
either mode exclusively.
Photocell Disable Mode
When the input goes high (+24V) the Power Pack
will disable the Photocell input, along with daylight
operation, and there will be no change in the
current state. The On switch functionality, when the
photocell is disabled, turns lights on to the
maximum level. When the input signal is removed,
the Photocell will return to the normal mode.
Force Off Mode
When the input goes high (+24V) the Power Pack
will turn off all zones. The Power Pack zones will
remain fully off until the Force Off signal is
removed.
B
Time Clock Input
Label: CLOCK
This signal will originate from a supervisory time
clock system and is a +24V input signal. When the
input goes high (+24V) the Power Pack will turn off
all zones. If the Blink Warn function has been
configured, the Power Pack will trigger the Blink
Warn cycle. If a switch is used to turn on the lights
during a period that the time clock has the lights
off, the system will go into a Blink Warn override
mode.
If both the Occupancy Sensor and the Time Clock
inputs are used, an active (+24 VDC) signal at the
Time Clock input only has the affect of changing
an Auto On configuration to a Manual On.
CLoad Shed Input
Label: SHED
This signal would originate from an energy
management system and is a +24V input signal.
When the input goes high (+24V) the Power Pack
will reduce the output load levels based upon the
position of the Shed trim pot.
In the event that you are in daylighting mode and
less artificial light is required to meet the target than
is required by load shed, the lights will remain at the
lower lighting level – meeting the target.

There is one Low Voltage relay output rated
for 1A @ 24V which can be switched between
HVAC and Emergency output functionality.
This terminal block is connected to the
Emergency Output / HVAC relay.
Jumper Settings
A three (3) position pin header is located
adjacent to the terminal block. The jumper
configuration of this header determines the
functionality of the relay.
HVAC
A jumper between pins 1 and 2 will result in
HVAC functionality. In this mode the relay will
change state when the room is occupied. In
occupied state NO (normally open) contact is
closed.
Emergency
A jumper between pin 2 and 3 will result in
Emergency output functionality. In this mode
the relay will change state when an
Emergency Input signal is detected. In normal,
non-emergency state the NO (normally open)
contact is closed.

STEP 6
Label: SWITCH 1; ON, OFF, +24V, PILOT
SWITCH 2**; ON, OFF, +24V, PILOT
**not available on all models
There is a maximum of two low voltage switch inputs depending on the model. Switch 1 provides control for
Zone 1 and Switch 2 provides control for Zone 2. There is only one Switch input for the three Zone model.
Switch Types
Set by DIP Switch: Block 2 Number 1
There are two general types of switch inputs; analog
and switched.
Analog
In analog mode, the input is expecting to see a 0 –
24 VDC or a 0 – 10 VDC signal which is used to dim
the light levels proportionately to the level of the
analog input.
Switched
In the switched mode, the input is expecting to see a
+24 VDC level to indicate that a switch is closed.
One Button Mode
The switch connected to these terminal blocks uses
the same button to turn on and turn off the lights.
Push the button once to turn on, push the button a
second time to turn off. The button signal wire should
be connected to the On terminal. No wire is required
at the Off terminal.
Two Button Mode
The switch connected to these terminal blocks uses
two different buttons to turn on and turn off the
lights. Push one button to turn on, push a different
button to turn off. The signal wires from each of the
buttons should be connected to their associated
terminals.
Supply
The +24V source terminal supplies the power
required to energize the Low Voltage switch circuit.
This source is shared with all circuits supplied from
the +24V power supply to a maximum of 120 mA.

does not require illumination no wire will be present.
The Pilot output connects to common to turn on the
pilot light in your control device.

STEP 5 CONFIGURATION DIP SWITCH SETTINGS – BLOCK ONE
Page 10
Emergency / Occupancy Sensor Disable
DIP Switch: Block 1 Switch 1
Label: EMERG / OCC DISABLE
This configures the response to a signal (+24V) at the OCC Disable/Emergency input terminal. If the switch
is in the off position (EMERG), the response to a connection to common will be to turn all relays on and raise
all 0 – 10V outputs to ten volts. During this condition no other control will have any effect over the outputs. If
this switch is set to on (OCC DISABLE), the Occupancy Sensor will be disabled and no change in the
current zone state will occur when +24VDC is received by the input. When the signal is removed, the Power
Pack will return to normal operation.
Force Off / Photocell Disable
DIP Switch: Block 1 Switch 2
Label: FORCE OFF / PC DISABLE
This configures the response to a signal (+24V) at the PC Disable/Force Off input terminal. If the switch is in
the off position, the response will be to turn all zones off by turning all relays off and lowering any 0 – 10V
outputs to zero volts. If the setting is on, a signal (+24V) will disable the Photocell allowing normal operation.
The load shed function, however, will be disabled. When the signal is removed, the Power Pack will return to
normal operation.
Local / Network Enabled
DIP Switch: Block 1 Switch 3
Label: LOCAL / NET ENABLED
The models covered by this manual do not have network capability. This switch should remain in the off
position.
Manual On / Auto On
DIP Switch: Block 1 Switch 4
Label: MAN ON/ AUTO ON
This switch determines the response to the Occupancy Sensor and the Time Clock signals. In the off
position (MANUAL ON) the Power Pack will turn on zones only with a switch input and the Occupancy Sensor
or the Time Clock input signal will turn the lights off. When in Manual On mode, if the lights are turned off by
the Occupancy Sensor input signal, there is a 30 second grace period in which detected movement will turn
them back on. The lights will turn on only by the MANUAL ONswitch, not by the occupancy sensor.
With this switch In the on (AUTO ON) position the Power Pack will turn on and off zones in response to
signals from the Occupancy Sensor or the Time Clock inputs.
If both the Occupancy Sensor and the Time Clock inputs are used, an active (+24 VDC) signal at the Time
Clock input only has the affect of changing an Auto On configuration to a Manual On.

Local / Auto Cal
DIP Switch: Block 1 Switch 5
Label: LOCAL / AUTO CAL
The setting activates the Auto Calibration cycle. For more information, see the discussion on the Auto
Calibration feature on page 21.
Photocell Slow Response / Fast Response
DIP Switch: Block 1 Switch 6
Label: PC SLOW / PC FAST
This setting determines the speed at which the system will respond to changes in light levels detected by
the Photocell. In the off position (PC Slow), the response time will be 30 minutes. In the on position (PC
Fast), the response time will be 30 seconds.
Burn In
DIP Switch: Block 1 Switch 7
Label: BURN IN/ OFF
This setting activates the Burn In feature. Lamp burn in may be desired for new fluorescent lamps. This
feature keeps lamps from dimming for a period of 100 run hours.
Open Loop / Closed Loop
DIP Switch: Block 1 Switch 8
Label: OPEN LOOP / CLOSED LOOP
The switch determines whether the power pack should operate in open loop or closed loop daylight
harvesting mode. In closed loop mode, the photocell should be sensing the amount of ambient or task
light in the room. In open loop mode, the photocell should be sensing the amount of light coming in
through the skylight or windows. For details on the two methods of operation, please see the discussion
on page 20.

Behavior: Tapping the ON button shall fade the lights to the daylighting level over three (3)
seconds. If daylighting is not active in the space, the ON button fades the levels to the
level of the maximum trim pot. Tapping the OFF button shall fade to off the lighting in the
zone over one (1) second. If either button is held, dimming shall continue until either
maximum or minimum is established or the button is released. While held, dimming is
three (3) seconds in both directions.
Two Button Mode (On Only)
Set by DIP Switch: Block 2 Number 1 and/or Number 4
Settings: ON
Connections: In this mode the switch should be wired so that the ON signal wire is landed on
the ON terminal. The OFF signal wire should not be connected. The switch common will
be fed from the +24 VDC terminal. Activating the ON signal input with a +24 VDC level
shall cause the associated zone to turn on.
Behavior: There are some cases when it is desirable to allow zones to be turned on manually,
but not off. The off function is controlled by an occupancy sensor or time clock. This is
accomplished by configuring the input in two button mode and only using the ON input.

ANALOG MODE BEHAVIOR (LEVITON LV230
SWITCHES)
Set by DIP Switch: Block 2 Number 3 and/or Number 6
Settings: ON = Analog
Set by DIP Switch: Block 2 Number 2 and/or Number 5
Settings: ON = 0 – 10 VDC, OFF = 0 – 24 VDC
Connections: In this mode, the ON input is connected to +0 –
10 VDC or +0 – 24 VDC varying input. The OFF input is
connected to a maintained contact, indicating whether the
lights should be on of off. Input impedance is 85k ohms.
Behavior: Analog mode allows for a dimmed override to be
applied allowing the user to set the temporary dimmed
level of the lights via a slider or other such input device. In
this mode, the miniZ expects either +0 – 10 VDC or +0 –
24 VDC at the ON input, which indicates the dimmed level,
and a maintained input to the OFF terminal indicating
whether the lights should be on or off. When using the
miniZ in a daylighting operation, the dimmed level is a
temporary override. After the override time (60 minutes)
has elapsed, the device will automatically return to
daylight harvesting mode.
The input can be set for two different voltage ranges.
When in this mode, a 0 VDC level signal represents off,
while a +24 VDC (or +10 VDC) level represents full on.
The zone is dimmed proportionally between these levels.
