Operating Instructions
Serial Interface System (SCH 664)
1.3 Control and operation elements
For the continuous operation of the interface system special manual operations e.g. on a keyboard are not necessary.
Only for servicing and checks the inserted printed circuit boards are fitted with the green and red control LED's and
switches as described below (see also the "drawing of front panels" on the following page).
Sensor interface board - SI
LED indications:
(U1/U2) Indicates the presence of the power supply of 12 V DC for the N18-ring potentiometer of the wind sensor or
other consumers e.g. sensors to be supplied from integrated DC/DC modules of the system.
(U3) Output U3 is not in use - the LED is off
(service) Indicates that the switch is set to the service mode - please refer to the switch function as described below
Switch
(operation) Effects an event message for internal mean value calculation only in the data acquisition mode of the
system; in the service position the LED is shining.
When working as a talker of NMEA 0183 messages the function is not in use for this application
CPU board - CPU
LED indicators:
(DA) Data acquisition LED is indicating the sampling of data from the sensor. Depending on the stipulated
sampling rate it is flashing up to six times per second.
(DP) Data processing LED is indicating the generation of NMEA 0183 data protocols. Depending on the
stipulated transmission rate it is flashing at least once per second.
Remark: In case of errors the LED will shine constantly or not at all
Button Reset of the controller system
Connectors: COM1/COM2 9-pole female sub-D connectors for service and maintenance only
Power supply board - PS
LED indicators:
(AC-power) Power input is connected and switched on
(DC output) Internal DC supply is switched on
(+ 5 V) +5 V DC output of the module is present
(+12 V) +12 V DC output of the module is present
(-12 V) -12 V output of the module is present
Remark: For a proper operation of the whole system all indication LED's mentioned her have to be illuminated (on).
The remaining LED's (solar), (battery charge) and (DC-output) are not in use in this application
Switches:
(AC-power) With these items an independent switching of AC input voltage and DC output voltage is possible -
(DC-output) for operation both have to be in the "On" position.
