The Adjustable Tension Spring is used to adjust the tripod turnstile's elasticity and return speed. You can rotate it in
clockwise direction to enhance and in anticlockwise direction to weaken the elasticity and return speed of the tripod
turnstile. See Figure 5-2.
Figure 5-3 shows the mechanical and electrical structure of this equipment.

Troubleshooting
Symptom
Troubleshooting
The indicator is not lighted when the
equipment is powered on.
It may be caused by the power supply or circuit.
Check whether the connection cable and power cable between are
damaged, or the wiring is loose.
The arms of the tripod turnstile cannot be
lifted manually after the equipment is
powered on.
It may be caused by the problem of relative components or drop-arm
solenoid.
1.
Check whether the stop base and turn plate withstands each other, as
shown in Figure 6-1.
2.
Check whether the drop-arm solenoid is operating. Check the work
status of the solenoid, as shown in Figure 6-2.
The tripod turnstile does not open after
authentication.
It may be caused by lack of permission or a circuit problem.
1.
Check whether the user has the permission to open the turnstile.
2.
Use a multimeter to check whether the NO and COM ports of the
access control system has a relay signal output.
3. Short-circuit the ports "K1, GND" and "K2, GND", if the turnstile is
successfully opened, it would be the problem of controller. In this
case, please refer to Attachment 2 Connection Diagram of Mainboard
and Access Control Panel to check the cable connection of the
controller.
