• Earthquake Reset: Press to reset earthquake fault.
• Unintended Motion Reset: With the Machine RM Inspection switch in the INSP position,
press the UIM RST button for 6 seconds to reset UIM fault and Emergency Brake.
• Fault Reset: Press to reset latching faults.
• PLD & Processor Resets: Steadily lighted indicators for the PLD and Processors indicate
proper function. Press the Reset to reboot the associated processor or PLD.
• Test/Pretest: Placing the car on Pretest causes it to service any registered car calls but not
respond to hall calls. When car calls are satisfied, the idle car will recall to the pro-
grammed floor or remain at the last floor served if no recall floor is programmed. Door
action at the capture floor is also programmable.
Placing the car on Test mode allows a technician or adjuster to exercise the car at normal
operating speed but disables doors to prevent entry. Car calls may be placed through the
touch screen.
• Machine Room Inspection: Placing the INSP/NORM switch in the INSP position puts the
car on machine room inspection operation. In this mode, the car will run at inspection
speed in response to the Enable and Up or Down switches being pressed and held. The car
will stop when the switches are released.
• Door Bypass: Placing a switch in the Bypass position will allow the car to be run in the
absence of the normal Car door and/or Hoistway door inputs (door limits, lock contacts,
position monitor).
• CPU Battery: Maintains power to clock (date and time) used by event log. If “Cell Battery
Volts Low” message is displayed, replace CPU battery with CR2032, lithium-manganese,
3.0 V, 225mAh, ANSI 5004LC. Battery can be replaced while power is on, but it is safer to
