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 in put 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.

B

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.

D

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.

Page 6

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.

Low Voltage Switch InputsI

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 provide s control fo r

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 supp lied from
the +24V power supply to a maximum of 120 mA.

CONFIGURATION DIP SWITCH SETTINGS – BLOCK ONE

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: F

This configures the response to a signal (+24V) at the PC Disable/Force Off input terminal. If the sw itch 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 disabl ed. When th e signa l is removed , th e Powe r Pack will re tu rn to
normal operation.

ORCE OFF / PC DISABLE

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: M

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 ON switch, 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.

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

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.

to the level determined by the position of the Load
Shed pot if it is currently higher than that level. If
the Load Shed pot is adjusted above the Max pot,
no change shall occur.

Default

The default position is center.

OAD SHED (SHED) input is active.

DAYLIGHT HARVESTING THRESHOLD

5

On dimmed models, these trim pots will be used to
determine the amount of daylight control that is
applied to each zone. The full range of rotation
represents 0 – 100% of the photocell’s foot candle
range. The procedure for adjusting these trim pots
is different depending upon whether the miniZ has
been set to operate as an open- or closed-looped
system. In open loop, if daylight harvesting is not
desired, turning the pots full (100%) shall disable
the feature and the lights on the zone will stay on
at the Max level.
In closed loop, the Threshold trim pot has the
added functionality that it can be used to exclude a
zone from dimming, as it relates to daylight
harvesting operation, by setting it to a value o f less
than 5%.

TRIM POT (THRESH)

Default

The default position is full on (clockwise).

DAYLIGHT HARVESTING OFFSET TRIM POT (OFFSET)4

Dimmed Model, Open Loop

In Open Loop mode, the Offset trim pot is used to enter the desired foot candle value from 0 – 100 foot
candles, at the photocell. A setting of 0 equals 0 foot candles, a setting of 10 equals 100 foot candles.

Dimmed Model, Closed Loop

In Closed Loop mode, the Offset trim is used to set the target photocell values. The trim pots scale of 0 – 10
represents the 0 – 10 volt signal of the photocell. If, however, you are using Auto Calibration, the Offset trim
pot defines the Light Loss Factor (LLF) applied to the target level. The LLF is 20% when the trim pot is set at 0
and 0% when the trim pot is at 10. The assumption is that auto calibration occurs when the lamps are new, the
fixtures are clean, and the room is performing to the initial lumen output not the maintained lumen output.
When the Offset trim pot is set to 0, the LLF is set to 20%. When the Offset trim pot is set to 10, the LLF is 0%.

Basic Model

On the basic model this trim pot sets the point that Rel ay 1 is opened. The photocell must remain on either
side of the trip point for the time determined by the Photocell Fast/Slow DIP switch setting before changing
states.

STEP 9 NOTES: DAYLIGHTING CONFIGURATION

WEB VERSION

Setup

To setup your device in either open loop or closed loop mode, please reference Step 5, Settings,
found on page 11 of this document. This section details with specific calibration and configuration of
your miniZ device when in each of these modes.

Open-Loop Operation

Typical open-loop systems employ a photocell positioned towards the daylight source (window,
skylight, etc).

Important! For best results, the photocell should receive as little electric light as possible.

To determine the setting of each of the PC Level trim pots, light meter readings must be taken
during the day with the electric lights off and during consistent daylight (i.e. if a cloud covers the sun
during meter recording, start over or wait for the cloud to pass). Position the light meter at the
photocell, pointing it in the same direction as the photoc ell. Record the value. Next position the
light meter at the work surface in the room pointing it towards the ceiling. Record the value.

Now calculate the ratio of the zone value to the photocell value for each room. Use the chart below
to determine the PC Level setting. For ex ample, if the photocell reading is 400 foot cand les and
Zone reading is 50 foot candles, the ratio is 50/400 = 0.125 (50

chart’s x-axis (Room/Photocell Ratio) and follow a straight line up until the diagonal line it
intersected. Then follow a straight line to the left on the chart to obtain th e trim pot setting. In this
case the setting would be 7.

1.0

400 = 0.125). Find 0.125 on the

Closed-Loop Operation

Closed-loop systems position the
photocell so that it measures the amount
of light in the room being controlled. It is
important to correctly position the
photocell so that it receives either the
average amount of ambient light or if
sensing task lighting that it is directed at a
surface which will reflect an appropriate
representation of the amount of task
lighting in the room.

STEP 10NOTES: BURN IN & AUTO CAL FEATURES

WEB VERSION

BURN IN FEATURE

Set by DIP Switch: Block 1 Number 7 = ON
The Burn IN feature of the miniZ Power Pack

provides an automatic initializing cycle for new
fluorescent lamps. The Burn In feature will
maintain the fluorescent fixtures at full
illumination levels for 100 hours. At the
conclusion of the Burn IN cycle the miniZ Power

Pack will enter normal operation.

When to use it

Some manufacturers of fluorescent lamps require
the lamp to be run at the full illumination level for
a ‘burn in’ period prior to any dimming activity.
This feature provides an easy method to satisfy
that requirement.

Start

To initialize this function, move the DIP switch
labeled Burn In to the ‘ON’ position. Observe:

The LED above the DIP switch will glow red and
will remain in that state until the cycle is
complete. The fluorescent fixtures will also be
illuminated at their full level when turned on until
all zones have been on for 100 hours.

Stop

The cycle can be stopped at any time by turning

off the DIP switch.

Observe: The red LED ab ove the DIP switch will

turn off.

Restart

To restart this function, move the DIP switch
labeled Burn In to the ‘ON’ position. Observe:

The observations will be the same as the Start
step.

Burn In and the Auto Cal features can occur

at the same time.

AUTO CALIBRATION

(CLOSED LOOP OPERATION ONLY)

Set by DIP Switch: Block 1 Number 5 = On
The Auto Calibration feature of the miniZ Power

Pack provides an automatic daylight harvesting
calibration. During the 24 hour calibration

period all fluorescent fixtures will remain at

full illumination levels and cannot be turned

off. The miniZ Power Pack will monitor the
Photocell readings to determine the lowest level
during the calibration period. This reading
typically occurs at night. At the conclusion of the

Auto Calibration period the miniZ Power Pack
will enter normal operation.

Note: Auto Calibration is only applicable to
closed loop photocell operation. When the
device is configured in open loop mode, auto
calibration can be activated but the results of
such will have no effect on the configuration
or output of the miniZ.

Start

To initialize this function, move the DIP switch

labeled Auto Cal to the ‘ON’ position.

Observe: The LED above the DIP switch will
begin to flash on and off in a steady pattern until
the calibration period is complete. The
fluorescent fixtures will also be illuminated at their
full level for the duration of the cycle.

Stop

The cycle can be stopped at any time by turning

off the DIP switch.

Observe: Th e red LED above the DIP switch will

turn off.

Restart

To restart this function, move the DIP switch
labeled Auto Cal to the ‘OFF” position and then
back to the ‘ON’ position.

End of Cycle

Observe: The LED will be on steady at the end of
the calibration period and the miniZ Power Pack
will automatically enter normal operation.
