2 Control System Specification General Requirements Control Cabinet A new MRL control panel shall be provided being of the enclosed steel cabinet type with finished internally and externally in powder coating or stainless steel (on request). The identity of all the contactors, relays, and other equipment in the controller shall be clearly indicated by means of permanent, heat resistant non-fade, plastic labels. The control cabinet will be of decorative design to be mounted within the architrave of the landing door frame. The depth of the control panel will be a minimum of 200m. Access will be from the front only. The cabinet door shall lockable from the outside only and will not require the use of key to lock the door. All cable entry will come from below. Within the control system cabinet a magnetic strip light with integral UK plug socket will be available. The system shall be Kollmorgen MPK400c serial based via the microprocessor controlled. Each control panel is to be provided with a visual display which is back lit showing the operating status of the Lift and incorporating LED indicators which show the following information: +5vdc & +24vdc present 6 x LED s indicating the status of the safety circuit LED to show a door reversal device has activated Display to show all control modes, in service, out of service, fire control ect Door sequencing Direction of travel Floor position 2

3 Emergency Electrical Operation The control cabinet shall be provided with a changeover switch to convert from NORMAL operation to EMERGENCY ELECTRICAL OPERATION, together with UP and DOWN buttons. When switched to EMERGENCY ELECTRICAL OPERATION the safety devices ie safety gear, buffer switches and overtravel limits will be over-ridden. If the car top INSPECTION/NORMAL is operated this will render the EMERGENCY ELECTRICAL OPERATION inoperative. Landing Control Off Switch The MPK400c will be equipped with a landing control off switch that will render the landing calls inoperative when operated and will park the lift with the doors open taking car calls only. Remote Overspeed Governor Operation The remote overspeed governor installed which cannot be accessed from outside the lift shaft will have a key switch provided within the control cabinet to operate and test the operation of the governor. A further push button will be provided to reset the governor. Fault Finding and Parameter Adjustment Interrogation and parameter adjustment must be available at all levels of access although a security password system will be available to limit the amount of access from the user. A maximum of 50 events will be stored providing full English text indicating the error entries. The floor at which the fault occurred or the nearest door side is to be indicated. The field will also indicate at what point in the travel the error occurred. The time and date to the second will also be displayed. Parameter adjustment will be made simple to all users and no special service tools or laptop computer programs will be required to change system parameters. Once the parameter is changed it will be automatically saved and in the event of a power cycle the parameter change will not be lost. The following monitoring devices will be standard within the control system: 3 Phase failure/phase reversal protection Start, journey and deceleration monitoring timers Automatic homing with door cycling and floor designation adjustment All control equipment to be protected by miniature circuit breakers not fuses Anti-nuisance features for all in car controls Earth terminals and full earth bonding Microprocessor based absolute car position reference system

4 A device shall be fitted that determines the lift machine temperature. The software will be capable of giving options to render the lift out of service at the next landing or to resume operation on reactivation of the thermal sensor. Lift alarm push button to be permanently illuminated even in the event of a power failure. The standard safety circuit control voltage will be 110vac. All internal wiring of the control system is to be colour coded to meet current standards. Information is to be provided within the control system door indicating which voltages are present according to the colour of the wires. UPS Back Up Support for the Mechanical Brake and Handwinding An Emergency Operation Panel (EOP) with UPS back up support shall be provided within the control system. On EOP will support the handwinding procedure of the lift and give audible and visual signals to assist the user in the safe release of passengers. The operation of the EOP will render the lift inoperative. The UPS battery back system will keep the MPK400c processor and absolute position encoding under power to enable feedback from the encoder to indicate position and lift speed. On brake lift the lift will move in the out of balance load direction to the nearest floor which will illuminate the zone LED and the audible warning. The system will also monitor the lift speed. In the event of an overspeed the audible warning will sound. This speed threshold will be adjustable via the MPK400c to suit the user. Controller Wiring, Terminations and Trailing Cable All control terminations will of Wago or Phoenix connector design. Each terminal will have a minimum of three possible wiring entries. All panel factory fitted wiring will have the corresponding Ferrell end to reduce any potential of stray wires. All wires are to be colour codes to suit the voltages running through them. The trailing cable will be plug and socket both ends. The trailing cable will be split into two sections of low and high voltage to reduce the likelihood of EMC radio interference and induced voltages. The option of LSF low smoke and fume cabling will be available on request. Frequency Inverter and Silent Operation 4 The frequency inverter shall be from Control Techniques SP range of drive units utilising the latest in contactor-less technology for silent operation. The frequency drive will be mounted within the lift shaft on a steel mounting plate in close proximity to the controller and motor. The drive will be accessed via a serial bus communication or DCP (Drive Control Protocol). The MPK400c processor will have the ability to access the full

5 drive parameters and monitoring functions. The drive must be able to interpret the load weighing system via DCP signals to predict the starting torque of the motor to completely remove the roll back effect of gearless operation therefore providing perfect starting characteristics for optimum passenger ride comfort. The frequency drive will be set to a minimum of 10khz switching frequency to maximising silent operation of the machine. Within the control system an Ethernet port will be positioned so full laptop access is possible utilising all the diagnostic and ride quality functions of the control techniques SP software. Load Weighing Device Depending on the mechanical arrangement of the lift car a load weighing device will be fitted the top transom of the car sling or to the underside of the car platform. The Kollmorgen KLM-D or KLM-I load weighing are to be installed together with the LMD load measuring module. The device utilises the LON bus serial communication system to provide the control system with the following information:- Minimum load Full load Overload Actual load from no load kg to max load kg in percent. This information is then provided to the drive unit to predict the starting toque of the motor. The control system MPK400c will have the ability to formulate the traffic flow within the lift car and give approximate values which can be viewed via the MPK400c. UPS Rescue System (Optional) On request a UPS based power system will support the controller and frequency drive during a total power loss shall be mounted within the lift shaft. The control system will sense loss of power and reboot the control system and frequency drive via the output from the rescue UPS. Once the control system is restored and the lift is outside the floor level with the door closed the control system will move the lift under low speed to the nearest floor level and park with the doors open rendering all car controls inoperative. The frequency drive will have the ability to sense a load condition and drive the lift in the out of balance load direction to the nearest floor level. At no point will the control system bypass any safety circuits or safety devices during this sequence. UPS Battery Support Circuit 5 The control system will have the ability to support the potential deterioration of the batteries within the UPS devices by monitoring the quality of the batteries. Each UPS device shall have an output which the control system will monitor. This output shall trigger when the UPS device detects the battery life is inadequate and potentially could fail in the immediate future. An event will be entered into the event log and a message

6 displayed on the LCD screen to indicate to the user the potential of failure. The message can be cleared via the display menu. The control system shall have the ability to instigate a simulation of battery loading to allow the batteries to work improving the life time and reduction in maintenance and replacement. The control system shall have the ability to sense when the lift is parked for long periods i.e. during the night, and start the battery loading simulation. The simulation duration can be adjusted using the display menu by the user. Landing Equipment and Wiring All landing equipment will be controller serially to reduce the shaft wiring and installation time. Each display element and push button system will be connected control system via remote modules plug and socket cables to reduce installation time. Option of LCD and dot matrix display will be available via this bus. Each LCD or dot matrix display will be mounted in a stainless steel faceplate and back box. Each unit will house the display and multi-tone gong module. The gong module will connect direct into the display module and operate one tone for up and two tones for further direction of travel. The gong will only operate on the answer of landing calls. Each display will simultaneously output a further direction arrow indicating the next direction of travel. If no further direction is present both up and down arrows will be displayed. Each landing push button with single button or fully collective will be mounted in a stainless steel faceplate and back box. Each unit will be prewired housing the push button (or buttons) plus en buzz module and network module. The push button will be dual illuminated and of anti-vandal construction but have a decorative look. 6
