The signaller subsystems are turned on according to logic shown on the Figure 6.
www.atestgaz.pl Configuration Configuration of the signaller with Modbus interface is done by using dedicated software (Sigma Toolbox). This software downloaded from manufacturer's website https://www.atestgaz.pl/en/product/sigma-toolbox A computer with installed software should be connected to the SBUS port of the device (see Table 2). The device will be visible at address 1. Possible parameters to be set: device address on the ExBus port, type of communication protocol and data transmission parameters (see also Table 8).
www.atestgaz.pl Do never leave spare lengths of cables inside the device. Bare wires or wires surplus may lead to a hazard of electric shock or equipment damage. Do never leave redundant cable cores not terminated inside the device. Incorrect routing of cables may result in impairment of the equipment immunity to electromagnetic interferences.
