Do not change the setting on the LSB rotary (address) switch on the module.
To reset modules back to normal operation, set MSB and LSB switches a s they were
initially.
Example of use
The analog output module can for ex ample be used to power a Panama Canal St eering
Light. The button setup on the control panel may look like the figure below.
In this group of two buttons, the upper button (Panama s teering)
will turn the output on and off.
The lower button (Light level) will increase the output level in
steps according to the table above, resetting to lowest level when
maximum is reached.
Connections and fuses
Power
There are two terminations for power; module power (24VDC) and power for the
outputs:
The 24VDC module power is connected on the module using regular screw
terminals. These are clearly marked and have double terminals for further
termination to other modules.
The powers for the outputs are split in two on the termination plug: Main power
supply and spare power supply. These shall only be fed from a common power
distribution terminal rail.
Fuses
Each output has two fuses, one for each wire. These are located adjacent to the
respective terminals on the output modules. Fuses must be as follows:
24V output modules: 4A Ceramic, Quick, 5*20mm, IEC -60127.
230V output modules: 2.5A Ceramic, Quick, 5*20mm, IEC -60127.
LED light output modules: 1.25AT, 5*20mm, IEC -60127.
RS-485 network
The network is connected on the top of the modules using RJ -45 terminals.
LEDs
There are four LEDs on each output module: Power indicates that logic power supply
(24VDC) is present to the module, Rx indicates messages received to the module, T x
indicate messages sent out from the module, while Fault indicate a failure in the module
or the main supply net is missing.
