Diagnostic Messages and Input/Output Signals

To speed up final adjustment and troubleshooting, become familiar with the Status and Error
Messages (see "Status and Error Messages" on page
betized Flags/Variables and Their Locations" on page
Note
It will also be helpful to become familiar with the Motion 2000 Controller's computer
HC-MPU Main Processor Unit" on page
page 5-6).

Onboard Diagnostics

Status LEDs - The Motion 2000 controller boards (HC-CTL-2, HC-MPU, HC-DVR) are
equipped with diagnostic LED's, which provide visual information regarding the computer's
inputs and outputs. A listing of the indicators on each board can be found in PC Board Quick
References (see "PC Board Quick References" on page
LCD Display - When the Motion 2000 Hydraulic Controller's computer (HC-MPU) is in the
DIAGNOSTIC MODE, with switches F1 - F8 in the down position, the LCD display provides a
description of normal and abnormal conditions. When the LCD displays NORMAL, in the car
status field, the system is ready for normal operation. A complete listing of the status and error
messages, their meaning, probable cause and needed response are found in the Status and
Error Messages table
The computer displays abnormal conditions in the same priority that the computer evaluates
them. For example, if the safety circuit is open and the system is also on Fire Service, the com-
puter will first show that the safety circuit is open and will expect this problem to be corrected
first. When the safety circuit problem has been corrected and the computer has recognized the
safety input, the diagnostics will then show the Fire Service indication. After successfully bring-
ing in the Fire Service input and Fire Service Reset, the computer will then show NORMAL on
the LCD display, provided that the system is not on some other function such as Independent
Service or Cartop Inspection operation. The display will show NORMAL only if everything is
normal. If the LCD display is showing any other message, an abnormal condition exists.

Absolute Floor Encoding

Absolute floor encoding allows the controller to read encoding vanes or magnets at each land-
ing and thereby identify the floor. Note: Absolute floor encoding does not apply to LS-EDGE.
With absolute floor encoding, the behavior of the car when power is turned ON is as follows:
• If the car is not at a landing when power is turned ON, the controller will generate a
Down/Up direction command and the car will move toward the closest landing, provided
that all abnormal conditions have been corrected. When the car reaches a landing and is
within the Door Zone (diagnostic LED DZF is On) with leveling completed (diagnostic
LEDs ULM and DLM are Off) the controller reads the floor code vanes or magnets and
corrects the Position Indicator. If the car is on Automatic Operation, and if a home floor
has been designated, the car will move to the home landing at this time.
• If the car is at a landing, within the Door Zone (diagnostic LED DZF is On) with leveling
completed (diagnostic LEDs ULM and DLM are Off) when AC power is turned ON, the
controller will read the floor code vanes or magnets at the landing and correct the Position
Indicator. Again, if the car is on Automatic Operation and if a home floor has been desig-
nated, the car will move to this landing to park.
