4.1 Maintenance
1)
General indications
The tripod turnstile should be inspected and cleaned at regular intervals in order to maintain
the components in good working order and to check for signs of wear. The following indications
refer to the installation where the average number of transits per year is equal to two million.
When the tripod turnstile is used in a dusty area, the regular interval for inspection should be
shortened. If used in the subway or the light rail station, the inspection interval is recommended
to be 6 months. The users are also encouraged to determine the interval according to their own
situation.
To avoid the risk of electric shock, always ensure that the electrical power is disconnected
before inspecting the mechanism.

Component
Lock arms and solenoids (Operation to be carried out with the power supply

solenoid shaft and spring, and do not grease the core of the solenoid—check that the shaft/lock
arm assembly moves freely.

by the spring should match that exerted by the damper. Generally speaking, the former need to be
slightly more powerful.
