Specifications include, but are not limited to: 1. Call-back Standards: Nominally expected four (4) per year to eight (8) excluding nuisance calls. 2. Minimum expected periodic servicing, checking and adjustments. a). Every two (2) weeks: ride the car, observe operation of control, machine, brake and motor. Clean and adjust as needed, check lubrication of machine and motor. b). Every thirteen (13) weeks: Test and record rectifier-voltages of control supply, normal landing switches and door operator. c). Every twenty-six (26) weeks: Check governor and governor tail sheave lubrication, all cables, adjust and lubricate as required. Clean and examine Saf-T-Edge, guide shoes, lubricate and adjust as needed. d). Every fifty-two (52) weeks: Clean oil and adjust all door hangers, check all control switches in hatch, including care and corridor stations. Thoroughly check all control parts in machine room, brake, machine, check gear clearance. Make sure all electrical connections are tight. e). Other: machine bearings should be drained, flushed and refilled every two (2) years and the door operator every four (4) years. 3. Doors and Door Operation: Frequency of inspections and adjustment. a). Car and Hoistway Doors: Clean and lubricate track and hangers as needed. Check backplate and hanger to door fastenings, relating devices to insure tightness. Check up-thrust adjustment and fastening (nominal 0.010” to track), should clearance exceed 0.035” it should be adjusted. Check tightness of relating devices. Door interlock adjustment to be set to permit the latch to drop within 3/8” or less of full closure. Check contact setting for pressure and contact wipe. Bottom door guides should be fastened tight and replaced when panel may be moved in and out by ¼” or more. Check and tighten non-vision wings/sight guards at each inspection. Final latch cam and spring adjustment to be set to fully close the doors to locking position when within 1” to 1 ½” of full closure. Car door contact should be set to prevent car movement unless door is 2” or less from full closure. b). Saf-T-Edge: Device should be checked semi-annual for freedom of movement to permit it to operate with even a somewhat glancing blow, but not sloppy permitting it to rub against door. Where retractable projection is used at the opening it should be slight but permit the door to be held open with a slight pressure on the edge, in closing, edge should permit door to reopen within 1-1/2” of full closure or less. Reopening action should be such that reversal of the door movement will occur at such a point or before the leading edge of the vane and door are in the same plane, i.e. at or before the complete collapse of the edge. Active contact line of the edge should be free of cuts or bulges. Control contact cable, and retracting cable, where used should be held clear of snagging on other moving parts. c). Door Operator: Check, lubricate, and adjust quarterly, where gear operators are used, gear oil level should be checked and the unit cleaned and flushed and refilled within five (5) years. Opening motions should be at design speed smooth start, slowdown and stop, with particular care being taken to avoid drag in the opening action as the door reaches full open position. Closing time should be adjusted to comply with the current requirements on kinetic energy and smooth start and stop. Closing adjustment should permit door reversal within travel of the Saf-T-Edge as above without further drift.
