54 ST7001+ Autopilot Control Unit - Owner’s Handbook
5 Installing the ST7001+
5.5 Functional test – repeater units only
If you have installed the ST7001+ as an additional control unit for an
existing autopilot system, complete the following checks to make
sure you have installed the control unit correctly.
Note: If you have connected the ST7001+ as part of a new autopilot
installation, you MUST calibrate the autopilot as described in
Chapter 6: Commissioning the Autopilot.
Switch on
1. When you have installed the ST7001+ control unit, switch on the
main power breaker.
2. If the control unit is active and the system operating, the control
unit will beep and display the control unit type (
ST7001) for
2 seconds.
3. After 2 seconds, the control unit will display the
STANDBY screen.
SeaTalk and NMEA connections
If you have connected the ST7001+ to other SeaTalk instruments or
control units, check the links as follows:
1. Select display lighting level 3 (
LAMP 3) on one of the other
SeaTalk instruments or control units.
2. The ST7001+ should immediately switch on its display lighting:
• if the lighting does not switch on, there is a fault in the SeaTalk
cabling between the ST7001+ and the other units
3. If you have connected an NMEA navigator to the control unit
NMEA inputs, check the connections as described on page 57.
Troubleshooting
• If the head does not beep, check the fuse/circuit breaker.
• If the display shows the
SEATALK FAILURE or NO DATA alarm
message, check the SeaTalk connections.
