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.
