る。 However, if you accidentally connect the detection line la to the power connection terminals 2a and 2b and the power line lb to the detection terminals 3a and 3b, the detection line la is simply connecting the detection switch. , relay 4 remains de-energized. Therefore, the NO contact r inserted into the detection signal path is maintained in an open state, and therefore no power supply voltage is applied to the detection signal processing circuit section A.
Detection signal processing circuit A is not destroyed. On the other hand, the neon tube 5 is energized through the current limiting resistor R and lights up, indicating that the connection is incorrect. On the other hand, when the power line la and the detection line lb are correctly connected to the power supply connection terminals 2a, 2b and the detection terminals 3a, 3b, respectively, the relay 4 is energized, closes the NO contact r of the detection signal path, and processes the detection signal. Connect circuit A and detection line la to detection terminal 3a,
3b and is in normal operating condition. Also, the power line lb and the power circuit section B are the power supply connection terminal 2.
They are connected via a and 2b, and power is supplied to them. The circuit in Figure 2 is a control circuit section for the motor M of an automatic door.This control circuit section 6 is comparable to the power supply circuit section B in the circuit in Figure 1, and when an AC power source is connected to the power supply connection terminals 2a and 2b. Power is supplied to the control circuit section 6, and operation becomes possible. The control circuit section 6 includes a right travel control circuit 6a, a left travel control circuit 6b, a brake circuit 6c, and a push operation control circuit 6d. On the other hand, the detection signal processing circuit A creates a signal for controlling the running of the automatic door based on the detection signal, and as described above, the detection signal processing circuit A generates a signal for controlling the movement of the automatic door.
Connect a predetermined AC power source to energize relay 4,
Detection terminal 3 with its NO contact r closed
The detection operation is started when a detection signal is connected to terminals a and 3b. It is comprised of a left/right progression circuit 7c that controls left and right progression, a brake timer 7d that controls braking time, a push timer 7e that controls push operation time, and a brake timer release circuit 7f that releases the brake timer 7d.

を開始できるという利点がある。 This invention connects a relay that is energized when a predetermined power source is connected between the power supply connection terminals, and inserts the NO contact of this relay in series between the detection signal processing circuit connected to the detection terminal and the detection terminal. In addition, a light emitting element that lights up at a predetermined power supply voltage is connected between the detection terminals, so even if the predetermined power supply is accidentally connected to the detection terminal, the relay's NO contact will connect the detection signal processing circuit and the detection terminal. This will prevent the detection signal processing circuit from being destroyed due to incorrect connection of the specified power source.Furthermore, if the connection is incorrect, the light-emitting element will light up to indicate the incorrect connection, so the user will not be aware of the incorrect connection. Furthermore, when a specified power supply is connected between the power supply connection terminals, the relay operates and closes the NO contact of the relay, connecting the detection terminal and the detection signal processing circuit, and this connection allows the detection signal to be output for the first time. This has the advantage that it can be input to the detection signal processing circuit section, and as a result, the detection operation can be started with a proper power supply connection.
