K2-1 to 2: External dimmer<br />
If the external dimmer input is used, the internal dimmer must be switched-off by<br />
removing the jumper JP4.<br />
In such case, the dimmer signal of the main <strong>Sigma</strong> 300 instrument K2-1 and K2-2 must<br />
then be connected to K2-1 and K2-2 of the <strong>Sigma</strong> 100, whereby the repeater unit gets<br />
dimmed along with the <strong>Sigma</strong> 300.<br />
Important: the device will get damaged if it is used as a repeater unit without<br />
removing the JP4.<br />
K2-3 to 8: Repeater outputs<br />
The <strong>Sigma</strong> 100 has three outputs for an analog meter or for a repeater unit. There is a<br />
separate zero and gain control system for each output. An output has been provided on the<br />
K2-1 and K2-2 to enable dimming along with the repeater units. The output voltage of this<br />
dimming signal is 15V and can control a maximum of 250 mA.<br />
