Reconnect the wire on the number 63 terminal. 10. Reset the fault by pressing the Z4 key on the ZELIO. Grounding check. This last test is to make sure the fuses will do their work in the event of a short circuit to any of the electrical components in the system. Attach a lead wire from an ohmmeter on the main ground terminal inside the BEC01Z3 panel, and with the other lead wire check that there is continuity (less than 0.3 ohm) between the ground terminal and all other metal surfaces near the safety switches or control buttons of the apparatus (panel back plate, near the parachute and cable slack switches, extreme limit, etc.). If neither of these checking procedures produce inconclusive results, contact ATLAS ESCALTORS’ service department for the next course of action to correct the issue. 12 Owner-performed maintenance and troubleshooting Only a qualified professional technician may install and service the technical aspects of this equipment. However, the owner is authorised to perform the following maintenance described below: Clean your ATLAS ELVOR elevator with a humid cloth and avoid scratches to the painted surfaces in order to preserve its “as new” appearance. In the event of a grid power failure, use the apparatus sparingly in order to avoid drainage of the backup batteries. The batteries will provide enough power for approximately 20 cycles (1 cycle = 1 up or 1 down movement of the platform). Any abnormalities, mainly oil leaks or unusual noise must immediately be reported to the manufacturer, its local distributor or to a qualified professional service technician. Problem The elevator platform is not responding to the control buttons. Verification In order to troubleshoot your elevator, check the probable causes listed in the table below and apply the corresponding solution(s). If none of the provided solutions solve the issue, call the manufacturer or the distributor of your unit. CAUSE Grid power failure (batteries charge depleted, if so equipped) Apparatus has no more power from any source One or more of the landing doors are not closed properly The cabin control buttons are not responding (locked). SOLUTION Wait for grid power to return. - Call an electrician - Recharge the batteries Make sure the door interlocks are properly latching the landing doors. Unlock the control buttons using the provided key. 13 Professional maintenance of the elevator 14 During the maintenance of the ELVOR-00 elevator, check the following elements and perform the necessary corrections as required. Every 6 months VEHICLE Free operation of the control buttons; Telephone working condition; Emergency lighting. By cutting off the power with the main switch, the emergency lights must come on; Alarm operating condition; Check the auto-levelling tolerances in case of an improperly closed landing door by performing the following steps: 1. Make sure the elevator car is located at any landing other than the bottom one; 2. Block the door interlock arm at the unlocked position; 3. Press the UP or DOWN button; 4. If the auto-leveller is working properly, it should bring the vehicle back flush to the landing floor before it can travel more than 100mm (4 inches). 5. If the previous step failed, adjust the levelling limit switch of the auto-leveller and repeat the test until the cabin floor and the door landing levels are flush, whether the car moves up or down. BUGGIES Tightening of the 3/8-16NC bolts; Vibration during travel; Wheel squeaking. NOTE: Inspect the parachute mechanism after performing the testing procedure described on page 7. 15 HYDRAULIC CIRCUIT General condition of the hoses; Tightness of all connectors; Perform several cycles in order to check for fluid leak from the cylinder; Cleanliness of the hydraulic pump; The oil quantity that can be seen through the translucent tank should measure between 280mm and 360mm (11 to 14 inches) for the large tank, and 180mm to 250mm (7 to 10 inches) on small tanks. Should it be necessary to refill the pump with more than 2 litres of oil, defective parts need to be replaced (use OEM parts only). Check the auto-levelling in case of oil leaks by performing the following steps: 1. Make sure the elevator car is located at any landing other than the bottom one; 2. Using the manual release mechanism to simulate an oil leakage, very slowly allow the vehicle to travel down for about 20mm (3/4 inch); 3. After stopping the manual release, if the auto-leveller is working properly, the car should be brought back up to the landing door; 4. If step 3 fails, there could be a conflict between the normal landing stop limit switch and the lower levelling switch of the auto-leveller; 5. Make sure the normal landing stop limit switch is released before the levelling limit switch of the auto-leveller is triggered; 6. If step 3 still fails, adjust the lower limit switch of the auto-leveller; 7. Repeat the same procedure for all landings except the bottom one. BATTERIES General cleanliness; Terminals free of corrosion and well tightened. PROTECTION CIRCUIT (also see annual inspection) Perform the system check according to procedures described on page 9. Cleanliness of the contactors. LANDING DOORS Lubricate the axle on the door interlock; Make sure the door closer (gas cylinder) is working properly; Door level is adequate; Clean door windows. 16 Every 12 months CABLES AND PULLEYS General condition of the pulley grooves; Tightness of the 1/2-13 eye bolt nuts; Replace both cables if either of the following conditions is found on either one of the cables: Cable diameter is less than 5.7mm (15/64) Corrosion presence More than one strand is broken NOTE: 1. Check for the lowering of the vehicle in an emergency situation such as the procedure described on page 6; 2. Use aircraft-grade, galvanized steel cable 7x19, 1/4" diameter, 7000 lbs mechanical strength. Use AOS-014 (aluminum cable clamps).
