CTL Diagnostic Menu
These diagnostics allow you to view car motion parameters (speed/distance) as the car moves
through the hoistway. This information in turn will help you make ride adjustments or trouble-
shoot ride issues.
The initial screen will show either METRIC or ENGLISH units.
1. To switch between Metric or English units, press N
once. (Pressing N a second time will back you out of
the menu.
2. With the desired measuring units displayed, press S
to begin diagnostics display. The initial display is for
CTL-A (Processor A on the CTL board), address zero.
This address displays the number of floors served —
two in this example.
3. To select the parameter to display, use the S button to move between digits (processor A,
or B, or address positions 0000 - 9999) — the selected digit will flash — and the Plus (+)
or Minus (-) buttons to change the value of the selected digit.
For example, to display to speed recorded by CTL Processor B the last time the car passed the
Down Normal Terminal switch S2, select CTL-B, address 0019.
• To find the address of the data you want to display, check the following tables.
• CTL-A and CTL-B independently collect information from the landing system posi-
tioning sensors. The information they display per address should usually match.
1.01 meters per second (Metric)
or
