NOTES
1. Motor Connections Ensure L4 is in the ‘PWM’ position. The 930-618 can be connected
with any of the drives that Cetrek supplies. Phasing can be reversed electronically once the
system is installed. See “Installation Settings” for further details.
2. Motor Supply The Heavy Duty Motor Supply and Light Duty Supply must be run
independently. Fuse the Light Duty at 5 amps. See “Drive Units” in the Installing Section for
the Heavy Duty fuse rating.
3. Solenoid Drives Should be connected as shown in the diagram below. Links L1 & L3 must
be cut, L4 must be moved to the ‘Spool’ position. Also ensure that adequate diode
protection is fitted to the Spool Valves to prevent reverse spikes damaging the FET’s in the
930-618. A suitable diode is IN5401 or equivalent. Cetrek units 930-102, 930-112 have this
protection built in.
4. Set SW2 to OFF for 930-700, 930-770 or no console connected to Port B, otherwise to ON. If
a 930-700 or 930-770 is connected as a second station the third station is not available.
5. Set SW3 to OFF if no console connected to Port C, otherwise to ON. Neither a 930-700 nor
a 930-770 can be used as a third station and the third station is not available if either of these
is connected to the second station.
6. If the C-net Compass (930-383) is used as a Compass Repeater DO NOT connect the white
wire to this unit. It is advisable to check your C-net Compass Manual for details of the
connections into the Compass unit.
7. 930-528 General Purpose Analogue Interface, see data sheet for connection details.
8. Navigator Inputs: Set SW7 for NAV1, SW8 for NAV2, ON for single wire output, OFF for two
wire output. Connect Digital Windvane- NMEA 0183 to NAV2. See the System Description
Section for SW7 & SW8 settings.
9. Set SW5 & SW6 to ON for 930-807 and to OFF for 930-801. There is no connection for the
brown wire on the 930-801. If connecting a 930-305 Rudder Indicator, follow instructions
supplied with the unit for phasing a, regardless of the Rudder Feedback phasing.
10. See data sheet for connecting Gyro to Gyro Interface.
