Questions on Field Devices
Q. Are the Reset Targets necessary when using a
pulsing selector?
Yes.
The reset targets are required at the terminal landings, as shown on the car top selector
installation sheet, to establish or reset the floor position at the terminal landings.
Q. Why are Two Position Indicators energized at the
same time?
With Floor Switches, if there is an overlap of the slowdown targets, or a Floor Switch
sticks on, then when the car hits a new Floor Switch, all floors that have a Floor Switch
input energized will be turned on.
If the problem happens intermittently, it is probably caused by a sticking Floor Switch. If
it happens regularly at a particular floor, there is probably an overlap between Floor
Switches. In this case, either separate the Floor Switches (or targets) so there is no
overlap, or turn on the "Short Floor" feature, described above in the features section.
Q. The doors do not operate properly on Fire Service
Check the Door Open and Door Close Limit Switches for proper operation. Most problems
with Fire Service are a result of one or both of these switches not operating properly. Also
check to make sure the correct Fire Code has been selected in the Adjustable Settings and
Features. Refer to the schematic adjustment sheet.
