Lock Screens; Multiple Dispatchers Linked For Emergency Power; Description Of Phase I Operation - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000
EMG SWITCH NORMALLY OPEN:
This parameter sets the polarity of the EMG input.

12.6.6 Lock Screens

After the dispatcher parameter menus there are additional screens to allow hall calls to be locked
and unlocked for each car by floor and direction. Car calls can be locked and unlocked through
these screens on the dispatcher for each car.
NOTE: These locks will not unlock floors that have been locked through hardware lockouts. If you
are using a remote locking system you will NOT be able to unlock these locks with the remote
system.
When setting up the dispatcher enter "Y" next to the floor to lock the floor for the up or down hall
call. If you wish to lock the car call for a particular floor then enter a "Y" in the car call column.
There is a screen for each car in the group.
After entering your selections save them to non-volatile memory by selecting the item on the main
parameter menu.

12.7 Multiple Dispatchers Linked for Emergency Power

If two or more simplexes or groups of cars are required to be inter-locked for Emergency Power
operation the inter-lock is accomplished via two inputs and two outputs per each simplex or group.
Below is a description of the inputs, outputs, and parameters that are used to link the dispatchers
together.

12.7.1 Description of Phase I Operation

The RET1 inputs and outputs are used to link the groups for Emergency Power Phase I. Each
dispatcher has an RET1 input and output. When going on Emergency Power it is assumed that all
the groups will receive the "EMG" signal simultaneously. The master dispatcher starts recalling its
cars one at a time. When the Phase I Recall is finished the dispatcher will turn on its RET1 output.
This output is wired to the RET1 input of the next dispatcher in the chain. When the next dispatcher
receives the RET1 input it will recall all of its cars. After the recall is complete it will turn on its RET1
output. This scenario will repeat itself until all the simplex cars and groups have completed the
Phase I Recall.
The last group or simplex car in the chain has its RET1 output wired to the Master dispatcher's
RET1 input. When it completes the Phase I Recall it turns on its RET1 output, turning on the RET1
input on the Master dispatcher. This will indicate to the Master dispatcher that all groups have
completed the Phase I Recall.
If a group is unable to complete the Phase I Recall it will be bypassed by turning on its RET1 output
after a user enterable amount of time as entered in the "INTERDISP EM PWR TIMES: PH I"
parameter. Losing the RET1 input after going on Emergency Power Phase I has no effect on either
the master or any subsequent dispatchers.
12.7.2 Description of Phase II Operation for the Master Dispatcher
Once the Master dispatcher sees its RET1 input turn on it will allow its cars to go back in service on
Emergency Power Phase II. It will only place a car in service if its RET2 input and output are off. If
the Master is able to place a car on Emergency Power Phase II it will turn its RET2 output off. If it is
not able to place a car in service it will turn on the RET2 output after one minute. Once the RET2
output is on the Master starts monitoring the RET2 input. If the input does not turn on in the
amount of time set via the parameter "INTERDISP EM PWR TIMERS: PH2", the Master turns off its
