Primary and Secondary Location 5.1

The positions of the primary and secondary corresponding to single-lane, dual-lane and multi-lane

are shown in the figure below.

Saturn-S4000 Series User Manual

Wiring Methods 5.2

The wiring principle is to connect the main device to the sub device and communicate via the ECU-

panel connection wire. Each main device is then powered individually. The following diagram shows

how the different channels are wired.

6 Operation Process

1. POST (Power On Self Test)

When powering up the unit, wait 30 seconds for the system to perform a POST (Power On Self Test)

procedure. If no problems are detected, the unit will operate normally. If a fault is detected, the

system will display a relevant message on the LCD display so that the user can quickly understand

and solve the problem. (Reference 5.3 Power and Circuit Breaker Wiring

for connecting the air

switch and power supply.)

2. Credential Verification

After the unit's power on self test is complete, you can test the door opening by pressing the KEY 5/

KEY 6 button on the motherboard.

Saturn-S4000 Series User Manual

When the user presses the KEY 5/ KEY 6 button on the main board, it is equivalent to recognizing a

valid card. The LCD display will show success and a buzzer will give a positive audible indication to

the pedestrian that it has been successfully validated. The card reader then sends a signal to the

access controller requesting permission to pass through the channel. The access controller will send

a signal to the revolving door control panel. After receiving the signal from the card reader and the

Infrared Sensor, the Turnstile Control Board will send valid control signals to the servo motor driver.

1) Verification Success

When the verification is successful, the door is opened.

2) Validation Failure

When verification fails, the door remains closed.

Note: At this time, if the system is in forbidden passing mode, the mode indicator light will turn red,

and the Turnstile Control Board will not accept signals of card.

3. Passed Through

After the passenger passes the channel according to the opening direction of the swing arm, the

Infrared Sensor will keep detecting the movement of the pedestrian throughout the passage and

continue to deliver signals to the Turnstile Control Board until the pedestrian passes through the

passage.

If the pedestrian enters without ID or an invalid card, the system will prompt an audible alarm. The

alarm signal will not be canceled until the passenger retreats from the passage. The pedestrian can

pass through the passage only after a valid card is successfully verified.
