2DESCRIPTION OF HMD230/IGD
The HMD230 is a drive unit intended for sliding gates of the types: Delta, uGate, SHB and Orion. The
IGD is a drive unit intended for sliding gates of the type iGate. These drive units enable gates to be
operated electrically (pulse or dead man's operation). Depending on the actual configuration, the gate
sliding speed will be 0.25 m/s (HMD230S, IGDP, IGDE) or 0.5 m/s (HMD230A, optionally for IGD).
Electrically driven Heras gates have anti-crushing safety protection devices. The type of anti-crushing
safety protection devices and the sliding speed depend on the gate motor drive used.
See the chapter on "TECHNICAL DATA" for further information.
The motor of the HMD230/IGD has a pulse generator enabling the motor control to determine the
gate position. Limit switches are not necessary anymore.
2.1 HMD230 PROFILES

3SAFETY
3.1 GENERAL SAFETY INSTRUCTIONS
The operator must read the entire user manual before the gate is used for the first time. The
instructions stated in the user manual must be observed and complied with. All other forms of
use can cause unexpected hazards and are forbidden.
It is forbidden to apply the drive unit to gates other than those stated in this manual, without
Heras' permission.
Applying a third-party drive unit and/or anti-crushing safety protection device may affect
safety and will invalidate the CE mark.
The gate must only be put into use if all safety facilities are in place and connected, and work
properly.
All faults which might present a source of danger to the user or to third persons must be
eliminated immediately.
All warnings and safety notices on the equipment must be in place and clearly legible at all
times.
The gate must be able to move freely without there being obstacles in the gate opening
passage or anywhere else on the moving trajectory of the gate.
Do not stick any objects through, over or under the gate which might block the gate. The gate
running surface must always be free from snow, ice or dirt that might affect its sliding
behavior. In the event of frost, check this before commissioning the gate. If the running
surface is blocked, the gate will not move at all or will not complete its movement. An
irregular running surface may cause damage to the drive and/or road wheels.
Climbing the gate is strictly forbidden as people climbing the gate could be hurt if the gate is
started unexpectedly.
Closing the gate infill openings in any way, such as by means of banners, advertising signs
etc, is not allowed as this may negatively affect the safe operation of the gate.
All alterations or extensions to the gate must be carried out by qualified personnel using parts
which the manufacturer has defined as suitable for such alterations or extensions. Any failure
to comply with these instructions will be considered as non-compliant behavior and will
invalidate the manufacturer's guarantee, as a result of which the risk entirely transfers to the
user.
Improper usage or servicing or ignoring the operating instructions can be a source of danger
for persons, and/or result in material damage.
If the meaning of any part of these installation and operating instructions is not clear, then
please contact your supplier before you use the equipment.

www.heras.com
English
13
3.2 SAFETY DURING INSTALLATION, DISASSEMBLY, USE AND MAINTENANCE
When work is carried out on the gate, the power supply to the system must be switched off
and it must be ensured that it cannot be switched on unexpectedly.
Interrupt the power supply while cleaning the gate.
Use the necessary personal safety equipment.
Keep a safe distance from the moving gate. Warning icons to this effect have
been installed in various locations.
The gate has safety facilities such as anti-crushing safety protection devices.
The anti-crushing safety protection devices serve as emergency facilities to immediately stop
and reverse the gate movement. Using them as a regular gate stop feature is not allowed.
Since the head stiles of the gate have anti-crushing safety protection devices that cannot
cover their full height, there is still some risk of people getting trapped by the gate here.
The gate is driven by means of a gear wheel. This is located under the beam and it
is partly screened off by the drive unit cabinet. Beware of moving parts when
carrying out maintenance under the gate at the drive unit cabinet.
To move the gate manually, first switch the automatic fuse in the drive unit cabinet to “off”
and make sure it cannot be switched on again (e.g. by locking the cabinet).
Always lock the drive unit cabinet during use. The drive unit cabinet may only be opened by
an electrical engineer.
The EN 13241-1, EN 12453 and EN 12445 standards must be taken into consideration during
installation. To achieve a good safety level, both the above standards and the national
regulations must be taken into account in non-EC countries.
The Delta, uGate and iGate have highly tensioned cables fitted in the bottom rail. If these
cables are damaged, they can snap with great force. This can lead to serious injury.
Therefore, it is prohibited to drill into or grind these rails.
!! Only people trained by Heras are allowed to disassemble the
bottom rail.
If the gate is damaged, always contact the supplier for an inspection.
4INSTALLATION
The sliding gate and the gate drive and control unit must be installed, connected, set up and tuned by
a fitter or an engineer who also connects and programs any accessories.
The gate control unit is adjusted to the options/accessories agreed with the user. The relevant options
are laid down during hand-over.
Of course, you can add optional/accessories afterwards. Contact your supplier for this.
Gates are always delivered fully tested.

7ACCESSORIES
The gate can be fitted with several electrical accessories.
7.1 ANTI-CRUSHING SAFETY PROTECTION DEVICES
Vertical switching strips have been fitted to the stationary and/or moving part or parts of the gate.
They are not required for dead man's operation. These strips serve as safety components. The
number of anti-crushing safety protection devices depends on the situation. See appendix A
"LOCATIONS OF ANTI-CRUSHING SAFETY PROTECTION DEVICES"
Before the gate is moved, the control system checks the status of the anti-crushing safety protection
devices. If one of the anti-crushing strips is faulty, the gate can only be opened and closed in dead
man's operation.
In that case, consult a qualified engineer.
See the chapter “SERVICE /MAINTENANCE”
7.2 PHOTOCELLS (OPTIONAL)
They detect the gate passage opening. Photocells are located on the stationary part of the gate and
usually take the form of a transmitter and a receiver. If there is an obstacle, e.g. a person between
the transmitter and the receiver, the gate will not close. The photocell does not affect the opening of
the gate.
7.3 LOOP DETECTION (OPTIONAL)
Safety loops in the pavement detect the gate passage opening. If there is an obstacle, e.g. a car on
the loop, the gate will not close. Detection loops do not react to people.
7.4 TRAFFIC LIGHT (OPTIONAL)
Red/green signal lights that indicate the open/closed position statuses. People are only allowed to
pass through the gate opening when the green light is on.
7.5 FLASHING LIGHT (OPTIONAL)
A flashing beacon to ensure extra attention before and while the gate is opening/closing.
7.6 RADIO-FREQUENCY RECEIVER (OPTIONAL)
Remote control to open, stop and close the gate.
See the chapter “RF REMOTE CONTROL”

www.heras.com
English
17
7.7 LIGHTING (OPTIONAL)
Two kinds of lighting can be connected to the HMD230.
Passage lighting to enhance the visibility of the passage opening. It can be lit before and/or
while the gate is opening/closing.
Outdoor lighting to illuminate the grounds. This is activated as soon as the gate is operated
and it is switched off automatically after a certain pre-set time.
See the relevant chapter of the “HMD230 motor drive” user manual
7.8 LED LIGHTING IN TOP RAIL (OPTIONAL)
The iGate can optionally be fitted with LED lighting in the top rail.
This lighting serves as atmospheric lighting. It is only lit if the gate is closed.
See the chapter “LED LIGHTING OPERATION”
Accessories must be installed and programmed by an engineer.
This requires entering the right password.

8COMMISSIONING
8.1 INTENDED USE
The gate is intended to control access to a specific plot, premises or site. The gate is intended for both
industrial and private use.
The gate drive and control unit is adjusted to the options agreed with the user. The relevant options
are laid down during hand-over.
Carefully read this user manual before operating the gate. You must always be familiar with
the operating mode the gate is in.
8.2 OPERATING MODES
The control software is divided into separate function modules and is available to users in three
possible operating modes:
dead man's operation
automatic mode
emergency operation (only for the Netherlands)
8.2.1 DEAD MAN'S OPERATION
The gate motor drive can be operated in dead man's mode with limited comfort. In dead man’s mode,
the gate does not require anti-crushing safety protection devices. The gate will move as long as an
OPEN or CLOSE key is pressed.
Dead man's operation is only permitted if the operator can see the entire gate system.
The drive and control unit must be fitted to the gate.
8.2.2 AUTOMATIC MODE
If the safety facilities have been installed completely, the motor drive will usually work in this
automatic mode. The user can only use all motor drive functions in automatic mode. Total safety of
the gate is guaranteed here by the activated safety facilities.
Opening or closing the gate can be initiated in automatic mode by means of the backplane and:
two command keys (OPEN, CLOSE)
one impulse input with toggle function (OPEN, STOP, CLOSE, STOP)
3x3 impulse inputs for OPEN, STOP and CLOSE commands
1 impulse input with PART OPEN function
Illustration 11: Backplane

www.heras.com
English
19
Every movement command causes the full action that has been selected to be performed (open gate,
close gate etc.). Every action is stopped immediately by a stop command or a signal from the safety
facilities.
Activating the anti-crushing safety protection devices causes the gate to immediately move in the
opposite direction. If a photocell is interrupted while the gate is closing, this will cause the gate to be
opened as far as the point where the closing movement started (OPEN or PARTLY OPEN).
A movement command for the opposite direction will gradually decelerate the gate and then cause it
to move in opposite direction.
Automatic mode if the gate has not been installed fully yet:
If the gate has not been fully installed yet, or if motor drive programming has not been
completed yet, the motor drive will work in a special safety mode (e.g.: the end positions of
the gate have not been defined yet). The gate will then only run at dead man's mode speed.
Only after the OPEN and CLOSED end positions have been set and after a measuring run at dead
man's mode speed has been performed, will the system switch over to the automatic mode speed
(depending on the type, HMD230/IGD, this will be 0.25 m/s or 0.5 m/s).
If the power supply to the drive has been interrupted, the gate will also only run at dead
man's mode speed until the first time when an end position has been reached.
8.2.3 EMERGENCY OPERATION
The gate motor drive can switch over automatically from automatic mode to emergency operation.
This automatic switch-over can only take place after a "Function emergency situation" input signal
which is generated by a fire emergency room. Only the one movement (OPEN or CLOSED, depending
on programming) that is requested will be performed at dead man's mode speed in this operating
mode. The safety facilities are also activated during this movement. The movement can be
interrupted by pressing and holding the STOP key or by a safety device being triggered. When this
interruption no longer applies, the gate will immediately continue to move. At the end of the
emergency movement and after the signal ("Function emergency situation") has been reset, the
software of the motor drive will initiate a restart to enable safe switch-over to automatic mode.
Any static active OPEN or PARTLY OPEN signals are ignored by the motor drive in this operating mode.
Just as the command triggered by an OPEN or CLOSE command key being pressed cannot be
performed when a program is started, a static active "Emergency situation" input signal will also not
be carried out when switching on the motor drive.
8.3 AUTOMATICALLY CHANGING OPERATING MODES
The gate motor drive can switch over from automatic mode to emergency operation if it has been
programmed to allow this and the HMD230/IGD recognizes a corresponding "emergency situation"
signal from a fire emergency room. This operating mode will then be performed until the motor drive
is restarted.
If electronic safety facilities on the gate are out of operation (e.g. faulty photocell), the motor drive
can automatically switch over from automatic mode to dead man's operation. This automatic switch-
over will take place only for the individual motor movement that has been started and only if the key
provided for dead man's operation is pressed. After this, the motor drive will switch over to automatic
mode again, but if a new fault occurs or if the fault is not remedied, the system can switch over to
dead man's operation again for the next movement.

www.heras.com
English
20
Changing between operating modes is possible in the following directions:
Automatic mode  Dead man's operation mode
Dead man's mode  Automatic mode (if safety has been restored)
Automatic mode  Emergency operation
Emergency operation  Automatic mode (if no emergency situation signal
is active anymore and after restarting the control
software)
