4 Low Voltage Connections Note that most signals have a companion ground connection, which is assumed to be chassis ground (battery minus). In case any particular input is not used, it may be left unconnected unless specifically noted below. <strong>Girard</strong> recommends AWG20-22 wire for all low voltage connections. 4.1 Anemometer Input [Pins 4 & 5 on PL403] To enable wind speed monitoring and emergency retract function, a two-wire anemometer must be connected between this input and ground. This input enables the ACMC to measure wind speed and take the appropriate action as described below. 4.1.1 Wind speed switch settings The ACMC measures the wind speed using the two-wire anemometer, and if this exceeds the preset threshold for 10 seconds, the ACMC goes into an override retract state. When the wind speed falls below the threshold for one minute, the ACMC comes out of the override state. In the override state, the ACMC will not accept any commands from the rf Remote. The wind speed threshold is set using the dipswitches situated on the lower right corner of the ACMC, as described below.

4.2 Retract, Extend and Stop Buttons [Pins 7, 8 & 9 (signal) and 6 (ground) on PL403] These inputs can be used as an alternative to, or instead of the rf Remote Control. External normally open switches should be connected between these inputs and ground. Three separate inputs are available for extend, retract and stop operation. It should be noted however, that an rf Remote is necessary for calibration and proper operation of the current limiter function. 4.3 Retract Limit Switch [Pin 10 (signal) and Pin 2 (Ground) on PL403] This switch automatically stops a retract operation, and all subsequent retract requests at the limit of operation (closed box condition) to prevent motor stalling. This input is activated when connected to ground. 4.4 Connect Button [Pin 2 (signal) and Pin 1 (Ground) on PL404] This button is used to establish an RF communication link between the ACMC and the ACS Remote Control. It is also used to initiate the motor calibration process. The Connect button can be extended to an external location using the connect button input, and a normally open push-button connected to ground. 4.5 Status LED [Pin 4 (signal) and Pin 3 (Ground) on PL404] The Status LED is used during the ID/channel learning process. The status LED may also be placed externally using the external status LED output. This output is powered from 3V and includes a 220-ohm series resistance. This output may also be used with other devices (e.g., a buzzer); please contact <strong>Girard</strong> for further details. 4.6 Low Voltage Extend Input [Pin 6 (signal) and Pin 5 (ground) on PL404] A switch to +12V can be used to control this input. This input is asserted when a voltage between 5 and 12V DC is applied. . The ACMC will extend the awning as long as a +12V signal is available on this input, to the limits of operation as determined by the extend limit switch. ACMC Installation Guide Rev 2.08 10
