If an encoder system is not supplied through the SMX module, a supply voltage still needs to be connected to terminal X13 or X15 and configured accordingly. The encoder supply must be protected with a fuse of max. 2 A. Monitoring of the supply voltage in accordance with the chosen nominal voltage: Nominal voltage Minimum voltage Maximum voltage 5 VDC 4.4 VDC 5.6 VDC 8 VDC 7 VDC 9 VDC 10 VDC 8 VDC 12 VDC 12 VDC 10 VDC 14 VDC 24 VDC 20 VDC 29 VDC HB-37350-810-01-10E-EN SMX installation manual.doc Page 18 of 18
Installation Manual 4.6 Connection of digital inputs DI1 to DI14 The SMX has 14 secure digital inputs These are suitable for connecting single or twochannel signals with and without cycling, or without cross-shorting test. The connected signals must have a "High"-level of DC 24 V (DC +15 V...+ DC 30 V ) and a "Low"-level of (DC -3 V...DC +5 V, type 1 acc. to EN61131-2). The inputs are provided with internal input filters. A device internal diagnostic function cyclically tests the correct function of the inputs including the input filters. A detected fault will set the SMX into an alarm status. At the same time all outputs of the SMX are rendered passive. Besides the actual signal inputs DI1 to DI14 the SMX module holds two clock inputs P1 and P2 available. The clock outputs are switching-type 24 VDC outputs. The clock outputs are solely intended for monitoring the digital inputs (DI1 ... DI14) and cannot be used for any other function within the application. The switching frequency is 125 Hz for each output. In the planning stage one must bear in mind that the outputs may only be loaded with a total current of max. 250 mA. Furthermore, approved OSSD-outputs can be connected to the inputs DI1-DI4 and DI9-DI14 without limitation Note: Digital inputs DI5 to DI8 are not suitable for OSSDs, because there is no compliance with EN 61131-2 Type 2 requirements. Short circuits in the external wiring between different inputs and against the supply voltage for the SMX must be ruled out by external measures, appropriate routing of cables in particular. Each input of the SMX module can be configured individually for the following signal sources: Input assigned to pulse P1 Input assigned to pulse P2 Input assigned to continuous voltage DC 24 V The internal structure of the SMX-series corresponds with category 4 of EN 13849-1 with respect to architecture and function. Each input has the following internal architecture: HB-37350-810-01-10E-EN SMX installation manual.doc Page 19 of 19
