Limit Switches Learn Fault, LIMIT SW LEARN FAULT
Description: Safety Processor A experienced a failure when storing learned limit switch speed values to non-
volatile memory.
Car Reaction: Emergency stop: Motor contactor and brake contactor immediately dropped.
Troubleshooting:
1. Press the Fault Reset button to clear the fault.
2. If problem persists, consult MCE Technical Support.
Load calibration on, LOAD CALIBRATION ON
Description: Load learn calibration has been initiated.
Car Reaction: Car will start load learn process.

Lobby Peak Mode, LOBBY PEAK MODE
Description: The elevator is operating in lobby peak mode, favoring traffic coming from the lobby.
Local / Dispatcher Activated, LOCAL DISPATCHER
Description: Communication with the central or local dispatcher has been lost or not established. This car
controller is acting as the Local / Dispatcher.
Car Reaction: The car establishes communication with all of the other cars in the group and starts perform-
ing the dispatching functions.
Troubleshooting: Check the system communication related connections and parameters.
Local / Dispatcher Deactivated
Description: This car is no longer performing the dispatching functions.
Loss of Position or Speed Indicators, LOSS OF POS/SPD IND
Description: The speed feedback signal used to compare with the position feedback signal is not being seen
properly or is not properly calibrated. This can be caused by a loss of traction.
Car Reaction: Emergency Stop. Latched fault.
Troubleshooting:
1. If this is an iControl with DC Drive using an encoder for speed feedback, this fault could indicate a mal-
functioning encoder.
2. On the iView oscilloscope (or a DVM connected between STP1 and STP2), compare Pattern Command
and Speed Feedback readouts. They must match within 0.050 VDC while the car is running at steady
state speed. If not, adjust the TACH ADJ trimpot. Please refer to “Calibrating Actual Car Speed (System
12 SCR Drive)” on page 2-62.
3. Use a hand-held tachometer to verify car speed.
4. Run the car on inspection and check the speed displayed on the iBox display.
Mac Address Error, MAC ADDRESS ERROR
Description: The iBox has detected that one of its three MAC addresses has been defaulted or set to zero.
This could lead to multiple cars having the same MAC address, which will cause network problems.
Car Reaction: None.
Troubleshooting: Remove the iBox front cover. On the iBox OBD select Car > View Factory Data > MAC
Addresses. Verify that the MAC addresses displayed on the LCD match the addresses on the barcode stickers
on the ICE-IMP board. Make corrections if necessary.
