Parachute testing procedure
1. Perform the following steps to test the parachute mechanism:
Load the elevator car with 940 pounds and block its down stroke
with a 2 x 4 wood beam, 1 meter long (39-1/2 inches);
Lower the hydraulic cylinder by approximately 75mm (3inches) in
order to produce a cable slack of about 150mm (6 inches);
Standing about 1 meter away from the car and using a piece of
wood, abruptly knock the 2x4 beam away. The elevator car should
come to a sudden stop within 60mm (2-3/8 inches) and a noticeable
slack should still be present in the cables.
2. Resetting the parachute:
Use an alligator clip as a jumper between the number 58 and 59
terminals;
Reset the fault on the Zelio logic relay by pressing the no. 4 key;
Raise the elevator vehicle to restore cable tension.;
Reset the parachute switch on the right side of the tower;
REMOVE THE ALLIGATOR CLIP.

each of the chargers, perform the following steps:
Disconnect the 2 chargers from the 120 volts AC outlet;
Perform 3 to 6 platform cycles in order to partially discharge the batteries;
Make sure that each charger is correctly connected to its corresponding battery:
red connector to the positive terminal and the black connector to the negative
battery terminal;
Connect each charger to the AC outlet. Both chargers should now have the red
indicator light on;
Connect an ammeter to the red wire of the charger to be tested, in series with
the positive terminal of the battery it is connected to;
If the measured current is over 0,5 amps, the charger is working properly;
When the battery is fully charged, the indicator light should remain off.

Protection circuit (redundancy) testing procedure
The following document describes the testing of the protection circuit in case
of failure (REDUNDANCY) of the elevator platform. This information is to be
used exclusively by a qualified service technician, accredited by Atlas
Escalators Inc.
WARNING:
THE
FOLLOWING
TESTING
PROCEDURES WILL PRODUCE MOVEMENTS OF
THE APPARATUS.
MAKE SURE NO ONE IS
STANDING BELOW OR ON THE ELEVATOR
PLATFORM WHILE PERFORMING THESE TESTS.
TESTING OF THE ACTIVE SECURITY
To execute this part of the procedure, remove the front face plate of the
elevator platform (EPF), if applicable, and open the panel of the BEC01Z3
controller.
C1 contactor (Main)
To check for the proper functioning of the C1 contactor’s active security,
perform the following procedure:
1. Using a screwdriver, push in and hold the C1 contactor plunger;
2. After 1.5 seconds, the ZELIO will fall in Fault Mode (the number 8 output
indicator will switch to inverted display).
3. Reset the fault by pressing the Z4 key on the Zelio.
4. Command an UP movement of the platform. The moment the movement
begins, keep the C1 contactor plunger depressed with a screwdriver and
10
press the Emergency Stop button. The EPF should come to a stop
rapidly. Release the UP button, the contactor and the Emergency Stop
button.
5. If the ZELIO falls in Fault Mode, reset the fault by pressing the Z4 key.
6. Disconnect the wire at the IG connector on the C1 contactor.
7. Press the UP button of the EPF. The ZELIO must fall in Fault Mode.
8. Reconnect the wire at the IG connector on the C1 contactor.
9. Reset the fault by pressing the Z4 key on the Zelio.
M1 contactor (UP movement)
To check for the proper functioning of the M1 contactor’s active security,
perform the following procedure (make sure the elevator car is not at its
uppermost position):
1. Using a screwdriver, press down and hold the M1 contactor plunger.
2. Briefly press the UP button.
3. After 1.5 seconds, the ZELIO will fall in Fault Mode.
4. Reset the fault by pressing the Z4 key on the Zelio.
5. Command an UP movement of the platform. The moment the movement
begins, keep the M1 contactor plunger depressed with a screwdriver
and press the Emergency Stop button. The EPF should come to a stop
rapidly. Release the UP button, the contactor and the Emergency Stop
button.
6. If the ZELIO falls in Fault Mode, reset the fault by pressing the Z4 key.
7. Disconnect the wire from IC connector on the M1 contactor.
8. Press the UP button of the EPF. The ZELIO should fall in Fault Mode.
9. Reconnect the wire in the IC connector on the M1 contactor.
10. Reset the fault by pressing the Z4 key on the Zelio.
11
Descent solenoid.
To check for the proper functioning of the descent solenoid, perform the
following procedure:
1. Make sure the elevator car is at its uppermost position (furthest possible
position from the bottom landing door).
2. Adjust down the descent speed rate. (Adjust to initial speed after tests).
3. Install an 18 gauge (or thicker) jumper wire between the number 60 and
66 terminals (therefore applying 24 DC volts to the solenoid coil).
4. Once the elevator car begins to drop down, press on the Emergency
Button. The car should stop very quickly and the ZELIO falls in Fault
Mode.
5. Remove the jumper wire from the number 60 and 66 terminals.
6. Reset the fault by pressing the Z4 key on the ZELIO.
7. Disconnect the wire at the number 63 terminal on the ZELIO.
8. Press the DOWN button of the EPF. The down movement should start
then stop after about 0.5 seconds and the ZELIO will fall in Fault Mode
(the number 8 output indicator will switch to inverted display).
9. 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.

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

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.
