ELECTRICAL CONNECTIONS
Figure 5.1 shows the protective plastic box of the control board. On the membrane label
located on the box, the connection diagrams of the input and output terminals and the functions of
the switches are explained. There is a reset button on the card to restart the control card. There is a
hole for access to the reset button, and you can reach the reset button by using a screwdriver to
reset the device.
The TEC-101 turnstile control card has LEDs on all inputs and outputs. It can be monitored
that the input or output related to these LEDs is working electronically.
The following figure shows the status and functions of the LEDs located on the control card.
Figure 5.1.1 Control Card LED Layout
These LEDs indicate the internal operating voltages of the turntable, that are + 5V and + 24V,
and that the turnstile works. The function of the corresponding LED is written on it. During the
breakdown, first it should be checked whether the + 24V LED is on, then the + 5V LED should be
checked. If the + 5V LED is off the control card is defective and must be changed without any
interference. The Run LED indicates that the processor of the control card is working. The Run
LED flashes during normal operation, if it is continuously on or off, the control board is faulty.
