Hz Motor Selection Guide

For Rolling Shutters and Doors

R

To select a motor in this guide you need to know the following:

1. Type of Slat: Height and Width

2. Total weight of shutter

3. Diameter of the tube

Type of slat:

It is important to consider the total size of the product you plan to
produce before choosing an operator, since these variables affect the
weight of what an operator can lift. The following charts represents
some of the most common motor solutions. Choose the one that most
closely corresponds to the weight that you calculate..

Total Weight of Shutter

Total weight = Width x (Height + Height of Housing) x Weight per sq. ft.

surface

Important Note:

The choice of a motor also depends on the type of installation.

- If you use one motor for two or more shutters add 20% for the first
additional shutter to derive the total weight. Add an additional 10% for
every shutter after that.
Examples: 2 shutters/one motor = + 20% to the total weight.
3 shutters/one motor = + 20% + 10% to the total weight.

- If the shutter is over 9 feet in height, add 10% to the total weight for
every three feet beyond.

h

h

Example: 11 feet in height= total weight + an additional 10% to the
effective load to be lifted.

Diameter of Tube:

The lifting capacity of an operator decreases when the tube diameter
increases. Therefore, it is necessary to choose the smallest tube while
considering the load capacity of the tube and the optimum roll-up
diameter of the slats. Keep in mind that if tube spacer rings are used, you
have increased the tube diameter.

After choosing the chart that corresponds to the tube size being used, select the operator according to the total weight of the
shutter.

1) Identify which limit adjustment screw controls the up limit and which controls the down limit (see above diagrams). It is important
to note that the arrows by the limit adjustment screw refer to the tube's rotation. Thus if the material comes off the tube on the back
side and the limit adjustment screws face the front (as per diagram 2), the limit adjustment screw facing up controls the down limit
and vice versa.

2) Turning an adjustment screw clockwise will increase the maximum travel in the direction that it controls, and turning it
counterclockwise will decrease the maximum travel.

3) To set a limit, run the motor in the selected direction.

4) If the motor stops on its own before reaching the desired stop, turn the appropriate limit screw positive (clockwise). Every 2 to 3
turns of the limit adjustment screw will allow the motor to travel about 1 inch further. After every few turns of the limit adjustment
screw, use the control switch to move the motor to the new limit position. (If the motor does not stop on its own before reaching the
desired limit, go to step 6)

5) When you are approximately at the desired limit position, use the control switch to run the motor away from the limit 2 to 3 feet,
and then back. This will allow you to see precisely where the limit is set. Make small adjustments and repeat.

6) If the motor does not stop on its own at least 6 inches before the desired limit position, stop the motor with the control switch.
Then turn the limit adjustment screw in the negative (counterclockwise) direction. Confirm that the motor is stopped at the limit and
set the limit as per steps 4 and 5. If the motor is not stopped at the limit, continue turning the limit adjustment screw
counterclockwise (up to 120 turns may be required )

NOTE: The motor has a built in thermal cutoff. If after several minutes of use the motor will not run in either direction, allow the
motor to cool for approximately 20 minutes.

DOWN LIMIT ADJUSTMENT SCREW

1) Identify which limit adjustment screw controls the up limit and which controls the down limit (see above diagrams). It is
important to note that the arrows by the limit adjustment screw refer to the tube's rotation. Thus if the material comes off the tube
on the back side and you are adjusting the limits from the side that the motor cable is not on (as per diagram 2), the limit
adjustment screw with the arrow facing up controls the down limit and vice versa.

2) Turning an adjustment screw positive (+) will increase the maximum travel in the direction that it controls, and turning it
negative (-) will decrease the maximum travel. For the adjustment screws on the side without the motor cable, turning clockwise
is positive (+) and counterclockwise is negative (-). For the adjustment screws on the side with the motor cable, turning clockwise

For the adjustment screws on the side without the motor cable,

For the adjustment screws on the side with the motor cable,

is negative (-) and counterclockwise is positive (+)

3) To set a limit, run the motor in the selected direction.

4) If the motor stops on its own before reaching the desired stop, turn the appropriate limit screw positive. Every 2 to 3 turns of the
limit adjustment screw will allow the motor to travel about 1 inch further. After every few turns of the limit adjustment screw, use
the control switch to move the motor to the new limit position. (If the motor does not stop on its own before reaching the desired
limit, go to step 6)

5) When you are approximately at the desired limit position, use the control switch to run the motor away from the limit 2 to 3
feet, and then back. This will allow you to see precisely where the limit is set. Make small adjustments and repeat.

6) If the motor does not stop on its own at least 6 inches before the desired limit position, stop the motor with the control switch.
Then turn the limit adjustment screw in the negative direction. Confirm that the motor is stopped at the limit and set the limit as
per steps 4 and 5. If the motor is not stopped at the limit, continue turning the limit adjustment screw (up to 120 turns may be
required )

NOTE: The motor has a built in thermal cutoff. If after several minutes of use the motor will not run in either direction, allow the
motor to cool for approximately 20 minutes.

-This device complies with part 15 of the FCC Rules. Operating is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) This device must accept any interference
received, including interference that may cause undesired operation.

-Caution: Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

2) Hz Operator Wiring

All wiring must conform to the National Electrical Code and local codes

-The Hz operator can be wired to power in parallel (unlike normal AC tubular operators)

-It is recommended that provisions be made to cut power individually when wiring Hz operators.
This can be in the form of an inline off/on switch, a disconnect plug, or access to the operator cable
for use of a installers power cable with off/on switch. The ability to cut the power to each motor
individually is required to easily program the receiver in the operator.

3) Installation

-The Hz motor uses standard T5 (not DMI) accessories.

-Use only SIMU accessories (brackets, adaptors, clips....)

-Mount Hz motor heads at least 18 inches from each other to prevent RF interference.

-Always install the power cable with a drip loop to prevent water penetration

-SIMU motors conform to IP44 requirements and as such must be protected against direct weather
elements such as rain, sleet, ...etc.

PROGRAMMING

Only power the motor you are programming. Cut power to all other motors until programming is complete.
Use a standard Hz transmitter to wake up the motor(s), check/set the direction of rotation, and program the motor.

STEP 1- Setting Direction of Rotation

Using a standard Hz transmitter, press the up and down buttons at the same time. The motor will give a small up/down bounce. This means the motor is
now awake. Press the up button. If the motor goes down instead of up, press and hold the stop button until the motor gives a short up/dn bounce. Confirm
the up button now makes the motor run up.

STEP 2 - Program the standard Hz transmitter

Note, you will not be able to program the motor until you “wake” it up. You must set the direction of rotation (step 1) before you program the motor. Press
and hold the Program Button (about 1 second) until the motor give a short up/dn bounce.

STEP 3 - Add the Hz Dry Contact Interface

To add the Dry Contact Interface transmitter press the Program Button on the transmitter that has already been memorized until the motor gives an up/dn
bounce. Press the Program Button of the Hz Dry Contact Interface transmitter until the motor gives an up/dn bounce.

transmitter.

-Motor does not respond to transmitter. Make sure the motor has been awaken by pressing the up
and down buttons on the transmitter simultaneously until the motor jogs forward and back.

A) Deleting a Transmitter

If a motor has two or more transmitters memorized it is possible to delete a transmitter from its
memory. On the transmitter you want to keep, press and hold the Program Button (about 3 seconds)
until the motor jogs forward and back. Press and hold the Program Button (about 1 second) on the
transmitter you want to delete. When the motor jogs forward and back the transmitter is deleted.
Note, if the transmitter was not in the receiver’s memory, it will be added instead of deleted.

B) Clearing the Memory of Old Transmitters and Adding a New Transmitter

If all a motors transmitters are lost or damaged, it is possible to clear the old memorized codes from
memory and add the new transmitter. Perform a double power cut in the following sequence:

1) Power off for at least 2 seconds

2) Power on for 5 to 15 seconds

3) Power off for at least 2 seconds

4) Power on
The motor is now in a Temporary Programming Mode (last for 2 minutes). The motor will attempt to
rotate in one direction for 3 seconds unless it is at a limit .
NOTE: THIS IS NOT “FACTORY MODE”. Press and hold the Program Button of any transmitter
for more than 5 seconds. When the motor jogs forward and back, release the Program Button. The
memory of the motor’s receiver is now cleared of the old transmitters and the new transmitter is added.

Solutions

If a motor or motors are entered into Temporary Programming Mode by mistake it can be canceled
by pressing on the up, stop or down button of any transmitter that the motor has memorized. The motor
will also return to normal operating mode if left for 2 minutes.

C) Returning to Original Factory Mode (Deleting All Transmitters)
Note: When the motor is in Factory Mode is the only time the direction of rotation can be changed
It is also recommended that the limits be set while the motor is in factory mode as it takes
continuous pressure on the transmitter button to move the motor

To return the motor to Factory Mode, make a double power cut as described in section (B). Press and
hold the Program Button of an already recorded transmitter. The motor will jog forward and back.
Immediately release the Program Button. The motor is now in Factory Mode. All transmitters are
cleared from memory. The motor will not respond until both the up and down buttons are pressed
simultaneously on a transmitter held within 10 feet. In Factory Mode, the motor will move only as long
as the transmitter button is held down. The direction of rotation can now be changed.

Hz2Inst Rev. B

2) Hz Operator Wiring

All wiring must conform to the National Electrical Code and local codes

-The Hz operator can be wired to power in parallel (unlike normal AC tubular operators)

-It is recommended that provisions be made to cut power individually
when wiring Hz operators.
This can be in the form of an inline off/on switch, a disconnect plug, or access to the
operator cable for use of a installers power cable with off/on switch. The ability to cut
the power to each motor individually is required to easily program the receiver in the
operator.

3) Installation

-The Hz motor uses standard T5 accessories.

-Use only SIMU accessories (brackets, adaptors, clips....)

-Mount Hz motor heads at least 18 inches from each other to prevent RF interference.

-Always install the power cable with a drip loop to prevent water penetration

-SIMU motors conform to IP44 requirements and as such must be protected against
direct weather elements such as rain, sleet, ...etc.

4) Setting Direction of Rotation

The motor must be in “Factory Mode”: requires continuous pressure on the transmitter
to run. The motor will be in “Factory Mode” right out of the box when power is connected.
If the motor is not in factory mode, or if you have any problems changing the direction of
rotation, go to step (9) Returning to Original Factory Mode below and follow the procedure
to change the motor back to factory mode.

Press the up and down buttons at the same time the motor will give a small up/down bounce.
This means the motor is now awake. Press the up button. If the motor goes down instead
of up, press and hold the stop button until the motor gives a short up/dn bounce. Confirm
the up button now makes the motor run up.

5) Setting the Limits (standard Hz only, for Hz DMI limit instructions see the catalog)

1) Identify which limit adjustment screw controls the up limit and which controls the
down limit (see diagrams on right). It is important to note that the arrows by the limit
adjustment screw refer to the tube's rotation. Thus if the material comes off the tube on
the back side and the limit adjustment screws face the front (as per diagram 2), the
limit adjustment screw facing up controls the down limit and vice versa.

2) Turning an adjustment screw clockwise will increase the maximum travel in the
direction that it controls, and turning it counterclockwise will decrease the maximum travel.

3) To set a limit, run the motor in the selected direction to it’s limit. You will know the motor
is at its limit when the motor will not run further in the selected when you release the
transmitter button and press it in the selected direction again.

4) If the motor stops at its limit before reaching the desired limit stop, turn the appropriate
limit screw positive (clockwise). Every 2 to 3 turns of the limit adjustment screw will allow
the motor to travel about 1 inch further on a new signal from the transmitter.
(If the motor does not stop on its own before reaching the desired limit, go to step 6)

5) When you are approximately at the desired limit position, use the transmitter to run
the motor away from the limit 2 to 3 feet, and then back. This will allow you to see
precisely where the limit is set. Make small adjustments and repeat.

6) If the motor does not stop on its own at least 6 inches before the desired limit position,
release the transmitter button and let the motor stop. Then turn the limit adjustment screw
in the negative (counterclockwise) direction. Confirm that the motor is stopped at the limit
and set the limit as per steps 4 and 5. If the motor is not stopped at the limit, continue
turning the limit adjustment screw counterclockwise (up to 120 turns may be required )

counterclockwise

NOTE: The motor has a built in thermal cutoff. If after several minutes of use the motor
will not run in either direction, allow the motor to cool for approximately 20 minutes.

SYNCHRONIZING CONTROL

Installation and Operation Instructions

DESCRIPTION

SOMFY'S Synchronized Control is designed to control two motors simultaneously. When two Somfy
motors are mounted in a single tube, moving a single window treatment, it is important that the
motors coincide with each other. The Synchronized control actuates and stops both motors at the
same time. This helps prevent damage to the tube, motor and window treatment. The Synch Control
comes with either momentary or maintained outputs to suit various installation requirements.

Part No: 1822159 Momentary Output
