2.7.6 Location of Machinery Spaces, Machine Rooms, Control Spaces, Control Rooms, and Equipment
NOTE: Inside the hoistway includes, but is not limited to, on or in the car, on the counterweight, or in the pit.
A motor controller shall be permitted to be located outside the specified spaces, provided it is enclosed in a locked cabinet. The locked cabinet shall be
(c) lit by permanently installed electric lighting with a lighting intensity of at least 200 lx (19 fc) at the floor level.
(d) located in a space that is provided with natural or mechanical means to keep the ambient air temperature and humidity in the range specified by the elevator equipment manufacturer to ensure safe and normal operation of the elevator. The temperature and humidity range shall be permanently posted on the cabinet.
(e) labeled/marked "AGP" in accordance with the requirements of CSA B44.1/ASME A17.5 (see 184.108.40.206).
(f) provided with a sign in conformance with the requirements of ANSI Z535.2 or CAN/CSA-Z321, which shall be prominently posted on the inside of the motor controller cabinet door indicating, in letters not less than 25 mm (1 in.) high, "DOOR TO BE CLOSED AND LOCKED WHEN ELEVATOR PERSONNEL ARE NOT PRESENT AT THIS CONTROLLER."
NOTE (220.127.116.11.2): For electrical clearance requirements, see NFPA 70 or CSA C22.1, whichever is applicable (see Part 9).
(a) the governor can be inspected and serviced from the top of the car or from an adjacent car, and the governor can be tripped for testing from the adjacent car or outside the hoistway; and means are furnished to prevent movement of the car when servicing the governor. A sign with the words "SECURE CAR AGAINST MOVEMENT BEFORE SERVICING THE GOVERNOR" shall be prominently posted and be visible from the governor. The sign shall conform to ANSI Z535.2 or CAN/CSA-Z321, whichever is applicable. The sign shall be of such material and construction that the letters and figures stamped, etched, cast, or otherwise applied to the face shall remain permanently and readily legible; and
(a) the direction of movement
(c) an indication of the speed
The display devices or the equivalent shall remain operable during a failure of the normal building power supply. The power source shall be capable of providing for the operation of the display devices or the equivalent for at least 4 h. Where batteries are used, a monitoring system shall be provided. In the event that during normal operation of the car, the monitoring indicates insufficient power to operate the display devices or the equivalent, the car shall not be permitted to restart after a normal stop at a landing.
(a) It shall not be dependent on the availability of normal power.
(c) It shall allow the car to move only with continuous effort.
(d) If the car is moved manually, the effort required to move the car in the direction of load imbalance shall not exceed 400 N (90 lbf). If the means used is removable, it shall be stored outside the hoistway, and access to the means shall be with a key that is Group 1 Security. The key shall be suitably marked to indicate the machine for which it is intended.
(e) Where the manual effort required to move the car exceeds 400 N (90 lbf), a means of electrical operation shall be provided to allow the car to be moved. This means of electrical operation shall require constant-pressure operating devices to move the car, and when activated, operation of the car by all other operating means shall be prevented. A failure of a single constant-pressure operating device shall not permit the elevator to move or continue to move. Where batteries are used for this electrical operation, a monitoring system shall be provided. In the event that during normal operation of the car the monitoring system indicates insufficient power to move the car, the car shall not be permitted to restart after a normal stop at a landing.
(b) the circuits of the following devices:
(1) the car-safety mechanism switch (see 18.104.22.168)
(b) have the required devices located behind a locked door or panel that does not open into the hoistway, is not self-closing, is self-locking, and shall be kept closed and locked. Keys shall be Group 1 Security (see Section 8.1).
(c) be provided with a stop switch conforming to 22.214.171.124.
(d) be lit by permanently installed electric lighting with a lighting intensity of at least 200 lx (19 fc) at the floor level. A switch placed inside or close to the enclosure shall control lighting of the enclosure.
(e) include the display devices required by 126.96.36.199.1.
(g) include the devices necessary for the manual reset of the detection means for ascending car overspeed protection [see 188.8.131.52(a)(4)] and protection against unintended car movement [see 184.108.40.206(a)(4)], where these devices are not accessible from outside the hoistway.
(h) where the circuits of the devices in 220.127.116.11.1(b) are not accessible from outside the hoistway, include landing inspection operation in conformance with 18.104.22.168.4, which shall be permitted to render ineffective the following electrical protective devices, individually or as a group or groups, in conformance with the requirements of 22.214.171.124.1(a), 126.96.36.199.2, and 188.8.131.52:
(1) the car-safety mechanism switch (see 184.108.40.206)
