ISSUE 15
The lift on hospital service will cancel all its car calls and landing calls, and temporarily remove any floor security in
place. The lift will then travel to the floor the hospital call has been placed, if the doors are currently open then it will
close them directly using nudging (if available), DOP to be ignored.
On arriving at the recall floor, the lift will open its doors and wait for a constant pressure car call to be placed onto
the lift. The doors will close and the lift will service the call. If no call is placed the service will time out and the lift will
return to normal service. On arriving at the selected floor, the lift will return to normal service.
If at any stage the lift develops a fault condition then it will cancel Hospital service.
Lift Alert Monitor
Prevents the lift starting a new journey if the system detects unintended movement.
Inputs: "MLA ", "Lift Alert Monitor"
Lift Isolation
Lift isolation takes the lift out of normal service, parking it at the next available floor.
Inputs: "LISL ", "Lift Isolated"
Limited Floor Service
Limited floor service provides an extra security map that is activated via an input, the real time clock, or both.
Inputs: "LTD ", "Limited Service"
LISI Self-Test
Allows the lift to put calls on so that the lift status is checked. Only active if [Self-Test Enable] is set and time is
within [LISI Daytime Start] and [LISI Daytime Finish].
Once active waits until car has been idle for [Test Delay Timer] time. Then the processor will place a call and the lift
will run to floor. Homing does not operate while in self-test mode.
Lift will then return to original floor after [Test Delay Timer] time. This will continue for [Max Number of Tests].
Load Weighing / 95% Load
Lift is on 95% Bypass and will not accept any more landing calls. If the car is fitted with a load sensing switch and
this switch is closed when the doors are closing, then the by-pass feature operates so that the car cannot stop for
intermediate landing calls and will only stop at the first car call encountered. Acceleration or retardation cannot
cause inadvertent operation of the by-pass feature.
Inputs: "WS95 ", "95pc weight switch"
Load Weighing / 110% Overload
Where the input WS110 is active the MPU will record the event, cause the doors to re-open and refuse to close until
the load is reduced. The event will remain displayed while this situation continues to exist, also the OLI output (Car
Overload Indicator) will be turned on. (Not active on Car Top Inspection Control).
Inputs: "WS11 ", "110pc weight switch"
Lobby Return
When on Lobby Return, all landing calls are cancelled and the entry of further car and landing calls is inhibited, but
existing car calls remain active. When the existing car calls are answered, the lift will then return to the predefined
Lobby Return Level where it will park out of service.
Inputs: "LRET ", "Lobby Return"
Low Pressure Return (if input assigned)
Available on hydraulic lifts, if the low pressure input is activated the car will recall to the lowest floor and shutdown.
Inputs: "LPI ", "Low Pressure Input"
Milkman’s Service
Milkman’s service takes the lift out of normal service and places control to a driver of the car. The driver places
single car calls to drive the lift to its required destination. Upon arrival at the destination, the lift will park open until
either the Cancel Milkman’s Service Timer expires or entry of a further call. The Cancel Milkman’s Service Timer will
start as soon as the milkman’s input is active. Should the timer expire or the input is present for a second time, the
lift will return to normal service.
Inputs: "MILK ", "Milkman's Service"
Remote Recall
Remote recall takes the lift out of normal service and parks the lift at its recall floor. It is control by TVC’s
E-Director system. E-Director provides a method of monitoring and controlling a lift from a PC.
