Part 1: Details of Regulated Product
The safety order is being issued in relation to a specific regulated product – specifically Richmond Elevator hydraulic elevator controllers installed to the CSA B44-M90 code edition.
The following issue was identified as the main causal factor during an incident investigation performed by Richmond Elevator and Technical Safety BC:
In the scenario where a leveling switch fails, the elevator will continue to operate but will fail to stop substantially level with the adjacent landing, creating a trip hazard to passengers loading or unloading from the elevator.
Clause 3.12.9(c)(ii) of CSA B44-M90 requires the occurrence of a single ground or the failure of any levelling switch shall not permit the car to move beyond the levelling or truck zone and clause 3.12.9(d) requires the car shall not be permitted to restart when a single ground or failure occurs.
The following models of controllers are affected:
Richmond Elevator hydraulic controllers installed between October 1, 1991 and December 31, 1994.
Non-compliances for units identified with Richmond Elevator hydraulic controllers installed between October 1, 1991 and December 31, 1995, will be automatically assigned to the associated operating permit(s).
Part 2: Requirement(s) Of This Safety Order
Verification of non-compliance and obtaining replacement parts:
Send the following information to Vladimir.Aniks@richmond-elevator.com, including the site address and (Technical Safety BC) unit identification number:
- Send the elevator to the top floor.
- Take a photograph of the Input/Output list on the front of the PLC that contains the inputs from the leveling switches (DL and UL) (see example 1).
Where required, Richmond Elevator will provide refurbished backplates with updated software for identified elevators and deliver the part to the licensed contractor performing this repair. The removed original backplates are to be returned to Richmond Elevator at the following address:
c/o Vladimir Aniks
12091 No 5 Rd, Richmond, BC V7A 4E9.
If Richmond Elevator confirms that a replacement back plate is not required, skip to Part 3: Reporting Requirements.
Repair Process
Once the replacement parts have been received, the following process is required to complete the repair:
- Place elevator on independent service operation at the lobby floor.
- Remove electrical power to the elevator at the machine room disconnect, following lockout-tagout procedures.
- Unplug the power supply to the PLC.
- Unplug all I/O cards.
- Remove the existing back plate – removing 4 connecting screws.
- Install the replacement back plate provided by Richmond Elevator – attaching with 4 screws.
- Re-plug the power supply to the PLC and re-plug the I/O cards.
- Restore electrical power at machine room disconnect to the elevator and restore elevator to normal operation to perform required testing.
Test Procedures
Test 1: UL Switch Failure – determine that a failure of the leveling switch UL does not permit the car to move beyond the leveling zone.
- While the elevator is at the floor, install a temporary a jumper from terminal 11 to terminal UL.
- Observe that the elevator starts moving in UP direction in slow speed.
- Observe that the elevator stops when it reaches the leveling switch DL.
- After 5 sec. observe two outputs on output card (1FL and TFL) start flashing.
- Remove the jumper.
- Observe that the elevator will not accept any hall or car calls.
- A manual reset is required to restore operation.
Test 2: DL Switch Failure - determine that a failure of the leveling switch DL does not permit the car to move beyond the leveling zone.
- While the elevator is at the floor, install a temporary a jumper from terminal 11 to terminal DL.
- Observe that the elevator starts moving in DOWN direction in slow speed.
- Observe that the elevator stops when it reaches the leveling switch UL.
- After 5 sec. observe two outputs on output card (1FL and TFL) start flashing.
- Remove the jumper.
- Observe that the elevator will not accept any hall or car calls.
- A manual reset is required to restore operation.
Test 3: Backplate I/O Verification - determine that the replacement backplate is functioning correctly.
- While the elevator is at the floor, place a jumper from terminal 11 to all car call terminals (1F, 2F, ..., TF).
- Observe that the outputs in the output card are activated (e.g., 1FL, 2FL, ..., TFL) and that the elevator responds to each car call appropriately.
- While the elevator is at the floor, place a jumper from terminal 11 to all hall call terminals (1U, 2U, 2D, ..., TD).
- Observe that the outputs in the output card are activated (e.g., 1UL, 2UL, 2DL, 3DL, ..., TDL) and that the elevator responds to each hall call appropriately.
Part 3: Reporting Requirements
Once the repair process and associated testing has been completed, the licensed elevating device contractor completing the repairs shall submit a report in the form of the non-compliance completion declaration form (FRM-1073). All repairs, testing and associated non-compliance completion declarations shall be completed by December 31, 2024.
Where Richmond Elevator confirms the existing backplate is compliant through the verification stage, report this by submitting a non-compliance completion declaration form (FRM-1073) with a copy of the confirmation from Richmond Elevator.
Where the Richmond Elevator hydraulic controller has been replaced with a model not referenced in this Safety Order, report this by submitting a non-compliance completion declaration form (FRM-1073) with a note in the “Date Completed” section stating “Controller replaced.
