- Page 14 EVSS ELECTRONIC FAN SPEED CONTROLLER WITH TK INPUT REGISTERS (See Table 1 Modbus register maps) The input registers are read-only. Table 1 shows how the data is organized in the input register sector. The measured data starts from address 1 (30001) and ends at address 14 (30014).
- Page 15 EVSS ELECTRONIC FAN SPEED CONTROLLER WITH TK the analog input signal is below the value of the OFF level (if enabled) or when the remote control input is disabled, the output voltage of the unregulated output L1 is 0 = OFF (0 VAC). Otherwise it is 1 = On (230 VAC). Input Register 13 (30013) shows the status of the alarm LED (Fig. 10).

Page 16: Transport And Storage
EVSS ELECTRONIC FAN SPEED CONTROLLER WITH TK Holding register 15 (40015) contains the OFF level state. The default value is ‘0’ (disabled). ‘1’ is for enabled. Holding register 16 (40016) defines the OFF level. This value depends on the selected analog input type and mode. The register values vary in the ranges of 0—40 (0— 4,0 VDC) for ascending voltage signal and 60—100 (6,0— 10,0 VDC) for descending voltage signal.
