Atwell International Limited
The System
Robust metal enclosure, Fail Safe Design, easy site wiring especially with plug and
socket option, where the sensors, brakes and controller will be connected via a
plug and socket arrangement to assist on site wiring.
Power feed and lift panel connections will be the responsibility of the end
customer.
Set of parts to be supplied in the full system include;
Control Box (UMD-SRB01)
Sensor Box (UMD-SP01)
Sensor Mounting Bracket and fixings
Set of 3 interconnecting cables,
32 Way interconnecting Hood,
Set of documentation (in English)
The Movement Detector (UMD-SP01)
The movement detector will be a fixed non-contact non-adjustable type.
The actual motion sensors are enclosed in a sealed enclosure to protect from
moisture, vibration and tampering. This is a non-serviceable component, any
doubt then it should be replaced.
The movement detector is sprung mounted to a bracket. The bracket is directly
mounted to the rope brake assembly. Alignment and tension to the rope can be
adjusted.
The Detector is constantly monitored, so if there is a fault with it or the
connection to it then an ALERT signal will be sent to the main lift panel. This is
to request the lift to be stopped at the next level, open doors then render itself
out of action. If the fault is detected whilst the doors are open then the brakes
will be deployed, because this is the worst case scenario and the system must
be fail safe.
The Controller (UMD-SRB01)
The controller will be enclosed in a painted steel enclosure suitably rated for the
lift control room. It is approximately 450mm long x 300mm tall x 150mm deep.
With the exception of replacing the battery and the relays every 3 years it does
not require any maintenance, other than periodical testing and inspection in
accordance with your site risk assessment and the lift regulations.
It contains a programmable safety device, display, visual and audible indicators,
key switch, battery, power supply and fuses.
The UMD-SRB01 controller has been designed and constructed to comply with all
current CE requirements, i.e. EMC, Low Voltage, RoHS, WEEE and more specifically
to meet the requirements of EN 81-80: 2003 5.9.4 Uncontrolled Movement with
doors Open.
With simple modification to the door wiring connections now also complies with
latest EN81-20/50:2014.
