2. OVERVIEW
Product description
The “HD5-B-xxx” is a three position enabling device with integrated AS-i technology. It operates in standard-
addressing mode, in accordance with the V.3.0 specification. (See “AS-i data” section)
The “HD5-B-xxx” enabling device is designed to be connected to the AS-i Safety-Bus and is available in a
range of configurations, which can be equipped with a maximum of two safe and one unsafe slaves.
There are two three-position enabling switches, which are both operated using one button providing a high
level of safety. The contacts are only closed in the middle position and are opened both when the button is
released and when it is pressed down further into the third and final position. Closing the contacts always
requires the contacts to be released. (See Functional description)
The signals from the three-position enabling switches and the emergency stop button (if the device is
equipped with this) are detected by the integrated electronics and transmitted to the AS-i safety monitor
via the safe slave.
Signals used to provide haptic or visual feedback are transmitted from additional integrated command
buttons and sensors to the AS-i logic and from the AS-i logic to the enabling device via a third, unsafe slave.
The enabling device is connected to the AS-i Bus in the usual way using a fixed spiral-cable or via a M12
connector built into the device.
If you have any questions regarding the existing configurations or the possibilities for a configuration
adapted to your needs, please contact ABB JOKAB SAFETY.
Application area
The enabling device is used in machines and facilities to provide protection to people, who, because of their
work (e.g. maintenance or installation work), move through danger zones in which other forms of
protection for users is neither possible nor practical.
Performing a risk assessment is essential for choosing protective devices. This should be done by the
manufacturer of the machine.
Caution!
Please note that failure to comply with the provisions and restrictions contained in this operating manual,
(e.g. in relation to the duty cycle, temperature etc.), may lead to loss of functionality of the enabling device
and to unintended machine stoppage.
If a shutdown has occurred, the enabling device will become functional again once the values drop below
the limits. However, there may still be damage to the electronics and a reduction in service life.

3. Functional description
Enabling button
The enabling button works in accordance with the three-position principle. This allows for
operators to be protected if the button is released or fully pressed down (e.g. if cramping).
An enabling button with three positions transmits signals, which:
•When activated, allow the machine or equipment to be initiated using a separate start
control and
•When deactivated, initiate a stop function which prevents the machine or equipment
from starting
Two three-position enabling switches are operated and analyzed redundantly to create a two-channel
architecture.
•The symbol for a three-position enabling switch identifies the three positions
(OFF, ON, OFF) using O and I, the movement direction from left to right, as well as the
possible ways to move the switch.
•An important feature of the three-position enabling switch is that when shifting back
from position 3, the ON position is not actuated, i.e. the contacts remain open.
The three positions function as follows:
•Position 1 (O): OFF mode (enabling button has not been pressed, contact is open)
•Position 2 ( I ): ON mode
(Enabling button has been pressed as far as the release position, contact is closed)
•Position 3 (O): OFF mode (enabling button has been fully pressed down, contact is open).
When released, the three-position enabling switches always go back to position 1, regardless of whether
they were in position 2 or 3.
Notice on operation
To ensure a correct and safe operation, the enabling button must be pressed in the middle
with two fingers or three fingers

2CDC172114M0201 9 www.abb.com/lowvoltage
2019-09-06 V1.3
Emergency stop button
The built-in emergency stop button is providing an emergency stop function for stopping
hazardous functions and removing power to them.
The emergency stop button has two forcibly-guided normally closed contacts.
Note on safe actuation!
To allow for the emergency stop button to operate safely, we recommend to use and assembly our holders,
designed especially for this enabling device.
Detailed description of this is to be found in the accessories section.
Attention!
Particular caution should be exercised in relation to enabling devices that are connected, as standard, using
a connector. Be aware of the following items:
•The correct function of the emergency stop must be check monthly!
•The emergency stop function must always be available and functional, and should have priority over all
other functions and operations in all operating modes of the machine without affecting any facilities
which are designed to release trapped persons.
•No start command (whether intentional, unintentional or unexpected) should be able to affect working
processes that were stopped by initiating the emergency stop function until the emergency stop
function has been reset manually.
•If it is possible to remove emergency stop buttons (e.g. portable programming devices) or shut down
sections of a machine, it must be ensured that operational and non-operational emergency stop
buttons are not mixed up.
Feedback on the functioning of the emergency stop button
•Feedback LED integrated into the push button of the emergency stop button
oRed LED can be controlled in a user-defined way via the AS-i Bus
Attention!
The controls for the feedback LED are independent from the emergency stop button function.
The programmer is solely responsible for their signaling function.
ABB JOKAB SAFETY does not accept any liability for damages of any kind caused by signaling that is not
logical, and the resulting misjudgments and errors by users.

Additional button No. 1
This button is built-in as standard and is located above the enabling button in the front area.
Its optimized ergonomic shape, as well as the tactile button beneath it, ensures it can be
operated easily and safely. This is usually done using the index finger.
Note on actuation!
The button must be actuated by pressing it down vertically, to an angle of between 0° and 15°. If the angle is
exceeded when actuating the switch, there is a possibility that the switch contact may be damaged, and the
switching cycles specified in the technical data will not be achieved.
Additional buttons No. 3 and No. 4
These buttons are installed on the grey housing. They can be controlled in a user-defined
way via the AS-i Bus.
Additional labelling of the buttons is an option for custom configurations.

2CDC172114M0201 11 www.abb.com/lowvoltage
2019-09-06 V1.3
Signal LED
The high-intensity LEDs are installed in the housing in such a way that they can easily be
perceived even in the normal ambient light in the workplace.
The controls are user-defined and can be controlled in a user-defined way via the AS-i
Bus.
Home position detector
A sensor, which can be implemented in the housing of the enabling device can recognize when the enabling
device has been hung-up in the specially-designed holder. (This holder is available as an accessory).
The signal from the sensor is transmitted via the AS-i Bus.
Attention!
This signal is not failsafe and shall never be used for safety purposes.
Assist light (flashlight)
This function acts as an assist light to illuminate work spaces for short periods in which the
ambient light is not sufficient.
The controls are user-defined and can be controlled in a user-defined way via the AS-i Bus.
When using these, you must comply with the following:
Notice on duty cycle
•On time = 60%, max. 15 min., ambient temperature ≤35°C
•On time = 40%, max. 10 min., ambient temperature > 35°C
•Calculation
oOn-time percentage = (on time/on time + off time) x 100
oOn time = (D%/100- D%) x off time
oOff time = (100-D%/D%) x duty cycle
Caution! Increased heat build-up
Compliance with the requirements is absolutely vital, due to the additional heat generated by the assist
light!
If the specified limits are exceeded, the possibility that the AS-i electronics may be damaged cannot be
ruled out.
Attention! Hazards arising from glare
Avoid looking directly into the lens of the assist light. Looking directly into the lens, and the glare effect
which may result from this, can sometimes impair vision, which may cause irritation, adverse effects, or
even accidents.

2CDC172114M0201 12 www.abb.com/lowvoltage
2019-09-06 V1.3
Vibration
A signaling device integrated into the housing of the enabling device, which can be controlled in a
user-defined way via the AS-i Bus, shall draw attention to an occurrence by causing the handheld
enabling device to vibrate.
Notice on duty cycle
•On time = 40%, max. 3 min.
•Recommended pulsed operation “On” 150 ms “Off” 250 ms “On” 150 ms....
•Calculation
oOn-time percentage = (on time/on time + off time) x 100
oOn time = (D%/100- D%) x off time
oOff time = (100-D%/D%) x duty cycle
Attention!
The user must be informed the manufacturer or operator of the system about function and if necessary,
instructed in order to detected potential hazards arising from the function.
Due to ignorance and possibly the following shock there is a risk of accident!
Status LED for AS-i Bus
One green and one red LED will inform you, about the status of the slave on the
AS-i Bus.
The LEDs are positioned in a way that means they are not directly visible when the
enabling device is placed in the holder intended for this purpose.
They are positioned in this way so that these signals are not confused with those
from the signal LEDs.
