Non-regenerative front end vacon • 187Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/11correctly and stays in run mode. If any of them is not correct, the phase monitor relay's output doesnot activate and the control unit gives an input phase fault.11.10.2 Option board settingsThe NXP control has fixed option boards A1A2BHB100. The option boards have jumpers which youmay need to set according to the external wiring and connections. See the VACON ® NX I/O BoardUser manual for settings. Required board settings for default wiring diagram and components aregiven below:Slot A, OPT-A1:• X1, AI1 mode: voltage input 0…10V• X2, AI2 mode: according to use• X3, CMA and CMB grounding: Connected to GND• X6, AO1 mode: according to useSlot B, OPT-A2:• No settingsSlot C, OPT-BH:• G7.3 parameters as shown in Table 92.Slot D, OPT-B1:• X2, DIO mode: DO1, DO2, DI3, DI4, DI5, DI6• X4: CMA grounding: Connected to GND. CMB grounding: FloatingSlot E: Reserved for optional board such as fieldbus1. "U" Green LED: Supply voltage• LED ON: Supply voltage present2. "MIN" Red LED: Lower threshold value (under voltage)• LED flashes: Set threshold value exceeded, set delaytime is running• LED ON: Set threshold value exceeded, delay timehas elapsed3. "SEQ" Red LED: Phase failure/phase sequence• LED flashing: phase has failed, set delay time isrunning• LED on: phase has failed, delay time has elapsed4. "REL" yellow LED: Output relay• LED ON: Output relay has picked up (OK)• LED OFF: Output relay has dropped out (Fail)5. "Delay" potentiometer: response delay• 400-690Vac: 0.1s6. "MIN" potentiometer: Lower threshold value• 400-500Vac: ≥360Vac• 500-690Vac: ≥450Vac11684_00156234
