Page 7: The System
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... -
Page 8: Signals
In addition to this there is a small visual display showing a text interface explaining the status and warnings. The UMD-SRB01 has two switches, one is an emergency stop button which when pressed will immediately deploy the brakes. The other switch requires a key to operate it, this is because regulations require a competent person to reset the brakes in the event of them being deployed. -

Page 11: Handling, Transport And Storage
If the Brakes, Cables, Controller or Sensor has been or suspected to have been damaged or exposed to moisture, they should not be used. Please return them to Atwell International for examination and re-test. The brakes, control boxes or sensors should never be lifted or carried by their cables. -
Page 12: Installation
Specific hazards arise for inadequate lighting, untidy work area, trip hazards and poor access. The Control Box (UMD-SRB01) It is recommended that the Control box is ideally mounted at approx 1.5 metres high on to a solid wall adjacent to the main lift control panel and close to the rope brake and monitoring pulley position. -
Page 13: Wiring
The 32-way connector is fitted so as to prevent the need for access inside of the control box. If you should need access to the inside of the control box please contact Atwell International for written consent as your warranty may be invalidated if the internal seals are broken. - Page 14 UMD-SRB01 enclosure and the terminal housing even when the fuses for the enclosure have been withdrawn. Within the UMD-SRB01 enclosure the internal connecting cables are coloured orange, this is so that you can easily identify them as potentially live, check them and beware of them.
- Page 15 In addition, a connection directly to the normally closed (when not in over speed condition) over speed governor switch is required. The operation of these switches is essential to enable the UMD-SRB01 to operate safely, i.e. If a cable is broken or the lift over speeds the UMD-SB01 will be FAIL SAFE.

Page 23: Uncontrolled Movement Settings
Uncontrolled Movement The UMD-SRB01 control box has factory set coding that allows it to receive 2 types of pulse counts from the UMD-SP01, these are the slow speed count Settings and the high speed count. The reason for this is to provide 2 different types of movement detection. -
