Also confirm that the car number setting for each of the car controllers is correct. This is
the third setting under “Settings” in the set up menu, as shown on the MH
-3000 Settings
sheet in the schematic. On the Dispatcher, check that the “Number of Cars” set
ting is
correct.
If none of the communication counters listed above are increasing, then the controller is
not trying to communicate. Cycle the power to that controller (or press the “Reset” button
on that CPU) to restart the communication.
4.11.4
Car Controller Settings
Refer to the MH-3000 Settings sheet in the schematic for the settings and features
available for each job.
4.11.4.1
Dispatch Failure Calls
The “Dispatch Failure Calls” setting is unique to Group car controllers. If the
communication with the Dispatch fails, then this setting allows car calls to be registered
automatically, to provide service to the building. The default setting is to enter the Main
Landing Car Call only. This will cause the car to return to the Main Landing and wait with its
door open. It will continue to respond to car calls normally.
4.11.4.2
Car Homing
The car can be forced to home to either the Dispatch Landing or the Alternate Home
Landing. This will override the automatic homing from the Dispatcher. It is recommended
that the Dispatch be allowed to home the cars, and that forced homing be left off.
4.11.5
Dispatch Controller Settings
Settings in the Dispatcher are changed in the same way as on the car controllers, as
described in this manual in the section on Settings and Features. There are some settings
that are unique to the Dispatcher, that allow it to be tailored to the building requirements.
These settings are normally set to the optimum values in the factory, so they should not
normally need to be changed.
Refer to the MH-3000 Settings sheet in the schematic for settings and features that are
provided on each installation.
Refer to this manual under the section on Settings and Features for the normal settings
and features that are provided on Group controllers. These include parameters that affect
the selection of traffic programs.
4.11.5.1
Zone Code Settings
Each landing must be assigned to one zone only. There should be the same number of
zones as there are cars, unless there are fewer landings than cars.
It is best if the zones are contiguous, that is that they contain consecutive landings with
no breaks in between. For example, do not set Zone 1 as landings 1 and 3 with Zone 2 as
Landing 2.
