Hortitek LMU Bedienungsanleitung

LIGHT MANAGEMENT UNIT

USER GUIDE

HORTITEK® LIGHT MANAGEMENT UNITS (LMU)

Enables gardeners to safely and easily control their grow lights.

The LMU serves 3 main functions:

• Time Control: Hortitek LMU can simulate any light cycle by using the 24-Hour timer.

• Power Control: Hortitek LMU can control, distribute and protect the load by using the

circuit breakers.

• Time Delay: This feature reduces the startup current and prevents voltage drop in the

network by staggering the ignition of the load.

1- L1242: MODEL NUMBER

2- LMU24: NUMBER OF TIMED SOCKETS

LMU24 = 24 timed sockets. These timed sockets

control the light cycle of connected ballasts using

the 24-Hour Timer.

3- 4LIVE: NUMBER OF LIVE SOCKETS

4LIVE = 4 always-on LIVE sockets. These can be

used for fans, pumps, heaters or other

appliances.

4- 12ON / 12OFF: SIDE A / SIDE B OPERATION

This indicates the number of HALF ON / HALF OFF

sockets. 12ON / 12OFF = 12 times sockets are on

while 12 time sockets are off.

5- 24ON: ALL ON OPERATION

This indicates the number of ALL ON sockets.

24ON = 24 timed sockets will be on at once.

6- TIME DELAY: LMU IS EQUIPPED WITH TIME

DELAY.

7- 1 PHASE/240V: INCOMING VOLTAGE TYPE

This indicates the incoming voltage type of the

LMU, either 1 PHASE/240V or 3 PHASE/415V.

8- 100A MAX: MAXIMUM PEAK CURRENT RATING

This is the maximum load that can be safely

supported by the LMU. This maximum should

only be sustained for 4 hours.

9- 80A CONTINUOUS: MAXIMUM CONTINUOUS

CURRENT RATING

This is the maximum load that can be safely

supported by the LMU in continuous, 24-hour

operation.

10- 50Hz: INCOMING POWER FREQUENCY

Both 1 PHASE and 3 PHASE power have a

frequency of 50Hz in Australia and New Zealand.

SET UP & OPERATION

All Lamps will turn ON

Note: To prevent a voltage drop in the

network, Hortitek LMUs are equipped

with Time Delay.

This function staggers the ignition of

lights sequentially by 1-2 minutes.

IMPORTANT NOTES

• Do not cover or obstruct ventilation openings.

• Do not obstruct the Circuit Breakers with cables or other

objects.

• Do not store or operate the LMU outdoors or in a moist

environment, or near water sources.

• To prevent exposing the LMU to high ambient

temperatures (above 40°C), avoid placing the LMU in the

same room as heat sources such as ballasts or lights.

• Sudden voltage increases can cause damage to your

LMU and related appliances. If you live in an area at high

risk of lightning strikes, it is highly recommended that you

have a licensed electrician install a surge protection

device between the LMU and the Incoming Mains Supply

cables.

The surge protection device should be of the same

current rating as the Main Circuit Breaker on the

switchboard. (All LMU’s are equipped with a fuse

and MCB’s to protect the unit and attached devices

from short circuits and overloading).

• Dust build-up in unused sockets on the LMU can

lead to reliability issues. Always ensure that unused

sockets are sealed off to maximise the longevity of

your Hortitek LMU.

• Always use a licensed electrician to connect your

Hortitek LMU to the Mains Power Supply.

Turn off all Circuit Breakers (CB) by

pushing the switches downwards.

Connect and tighten the supply

Earth to the LMU Earth lug.

If applicable, set your desired LMU

function using the selector switch

(Refer to selector switch guide).

Set your desired light cycle by

adjusting the 24-hour timer (Refer

to 24-hour timer guide).

Have a licensed electrician connect

the LMU supply wires to the

incoming power supply using the

wire connectors provided.

Note: When connecting the LMU supply wires,

ensure that the incoming power supply wires

are of equal or greater size/gauge.

MAIN

Connect all lamps to their respective

ballast, then connect the ballasts to the

LMU. Refer to the Lamp Distribution

Guide provided with your LMU to prevent

Overloading.

Turn ON the Main Circuit Breaker, next

turn on all other Circuit Breakers

one-by-one with a 10-second delay

between each, by pushing the switches

upwards.

A & B

Connect the control cable to the

PowerPoint and turn the switch ON.

Hortitek LMU’s 24-hour timer has 2 modes

Automatic and Permanent

PERMANENT MODE

To override the timer, set the timer switch to

Permanent Mode, this disregards the position of

any pins and sets all LMU sockets on.

AUTOMATIC MODE

Ensure the timer switch is on Automatic Mode.

This is the default and recommended setting

when using Hortitek LMU.

Setting the time: Turn the timer clockwise and

point the arrow on the face to the current time.

The Timers on Hortitek LMU’s have 96 red pins,

with each pin representing 15 minutes (4 pins = 1

hour). Use the red pins to set your 24-hour cycle.

When pins are facing inside, the sockets

connected to the timer A and B are off; and when

the pins are facing outside, they are on. This can

be used to simulate day and night such as 12

hours on, 12 hours off continuously.

The operation of the Timer depends on which

function the Hortitek LMU selector switch is set.

SELECTOR SWITCH GUIDE 24-HOUR TIMER GUIDE

For models that include a Selector Switch, it can

be used to control how many lights are active in

each on/off cycle. That is, gardeners can choose to

have half of their lights on, while the other half

are off.

This is highly useful in situations where gardeners

have more than one grow room set up and wish to

keep them on different light cycles to prevent

excessive power draw. Other beneﬁts include

reduced heat generation, or simply to maximise

their usage of their energy supply with lights

operating all day as opposed to only half the day.

SELECTOR SWITCH - HALF ON / HALF OFF (A or B)

In the I position: The Timer will turn Side A sockets

on and Side B sockets off. When the Timer turns

Side B sockets on, Side A sockets will turn off.

SELECTOR SWITCH - ALL ON (A & B)

In the O position: The Timer will turn both Side A

sockets and Side B sockets on simultaneously. It

will also turn both Side A sockets and Side B

sockets off simultaneously.

A Selector Switch will alter the way in which the

Timer is used to control the light cycle. Further

explanation is given in the following pages.

Red pins facing outside will cause all sockets to

turn on.

Red pins facing inside will cause all sockets to turn

off.

For example, the Timer below shows 24 pins facing

Inside, and 72 pins facing Outside. When the Timer

is on the Outside pins, all sockets will be on for 18

hours. When the Timer is pointing to the Inside

pins, all sockets will be off for 6 hours.

HALF ON / HALF OFF

Red pins facing inside will cause Side A to turn off,

and Side B to turn on.

Red pins facing outside will cause Side A to turn

on, and Side B to turn off.

For example, the Timer below shows 48 pins

facing Inside, and 48 pins facing Outside. This

means that one side (Side A or Side B) is on for 12

hours, while the other side is off for 12 hours.

C- If using 800W lamps, the maximum number of

• If using 600/630W lamps, the maximum

number of lamps allowed to this LMU’s timed

sockets are 24pcs and 6A maximum for the live

sockets.

HOW TO READ THE DISTRIBUTION GUIDE

The Distribution Guides included with all Hortitek

LMU’s have been specially designed to distribute

the power evenly on the LMU and protect against

overloading. It eliminates the guesswork in setting

up your lighting system.

Each lamp has been colour-coded:

SAFETY PRECAUTIONS TROUBLE SHOOTING

• Connecting more lamps than suggested in your

model’s lamp Distribution Guide may cause

overloading.

• If faulty ballasts are connected to the LMU, this

will increase the current (Amps) drawn and will

cause overloading.

• Overloading of the LMU causes high

temperatures within the unit and puts a lot of

strain on all of the components. As a result, it will

damage the LMU and decrease its service life.

• Do not mount the LMU in an enclosed space.

• Ambient temperatures for safe operation of the

LMU must be lower than 40°C.

When connecting a ballast to its socket on the LMU,

follow these steps:

• Turn off the related Circuit Breaker (CB) by

pushing the switch downwards.

• Connect the ballast to the Socket.

• Turn on the related Circuit Breaker (CB) by pushing

the switch upwards.

Always use a licensed electrician.

about Trouble Shooting.
