LOW TANK OIL

     M  

Explanation:

   E

The oil level input signal is low when the car is at the bottom landing. The oil level level sensor will detect oil loss at approximately 4.5 gallons. Oil loss is usually due to leaking cylinder or cylinder packing.

   C      N    E

Causes:

     R

•

 

Leaking Oil – Verify location of missing oil; reclaim reclaim/recover /recover if possible. If location cannot be determined, unit must remain shut down until missing oil has been conclusively located. Empty pit can. If can needs to be emptied more than once every three months, replace packing and correct leakage. Report problem to your Supervisor.

 

Check for leaking cylinder packing and check cylinder for leaks.

Door System – Something is bloc blocking king the doors or causing them not to close.

•

Door Lock – Lock is not making. Early versions of Dover ®   software will cycle doors six times then keep them open; car will not enter shutdown mode as in later versions of Dover Dover ®  software.

•

Stuck Car Button – Button is stuck in the active state.

A run was started, but the car failed to complete the run within the “INOP6 to UNOCC6” REM ®  config configuratio uration n timer. Some of the early ear ly versions of Dover ®  software did not provide down stall protection. Causes: •

Run Circuit – Check down run circuit relay contacts on relay board.

•

Valves – Valves failed; start star t with down valve.

•

Relay Board – HW2, HW3, CST, CST, DN1, DN2, VMR, or UP2 relays.

•

Switch Tree – Bottom directional limit (BDL).

LOW BATTERY - REPLACE  BATTERY Explanation:

The REM ®  main unit detected low backup battery voltage and the battery cannot be recharged. This message is indicative of future problems with the REM ®  unit failing to report problems when expected. Causes: •

Connections - Verify batter battery y termi terminals nals are clean, tight, and free from corrosion. Check for battery leakage and case swelling.

•

Batter Battery y – Replace REM ®  backup battery batter y at next regular visit or sooner (REM ®  5 battery p/n AAA718E3).

SLOWDOWN INTERRUPT FAULT Explanation:

As the car activates the SI signal, this message indicates indicates that it is time to slow down into a floor. floor. The message is sent from the selector to the CLC at the slowdown point. This 24-volt signal originates at connector CS9, pin 3, of the selector then goes to terminal block CSX2, pin 7, then to the CLC connector LCC11, pin 18. If the selector board is mounted on the side of the controller controll er where the wires are run with door signals or through the door doo r operator operator,, noise may cause intermittent faults. Causes: •

DC Power – Current setting for starter star ter may be too high, causing 24-volts to drop when car starts.

•

CLC Board – Check connector at LCC11, pin 18. Replace board.

•

Selector Board – Check wiring CS9, pin 3, through through to CLC board. board. Move wire away from door control signals if noise is indicated. If interrupt is indicated as failed, transistor Q5 on selector board may have failed.

FRONT DOOR LIMIT PROBLEM Explanation:

The doors were commanded to open or close but failed to reach the limit (DOL or DCL) within the time specified by CLC configuration parameter “door ffail ail time”. The signals that contribute to this fault are gate switch (DR), door close limit (DCL) or hoistwa hoistway y lock (HWP) for the closing direction, and door open llimit imit (DOL) for for the opening direction. The e event vent buffer and the second line of the message will be very ver y helpful. DR is the gate switch, HWP is the hoistwa hoistway y locks, DCL is the door close limit on the door motor shaft, and FDOL is the status of front door open limit. The gate switch, DR, should energize 1.5–2 inches from fully closed. The hoistwa closed. hoistway y lock should should follow DR and energ energize ize before DCL. DCL shoul should d energize about 0.375 inch from the final stop and should remain energized once the doors have stopp stopped. ed.
