correctly and stays in run mode. If any of them is not correct, the phase monitor relay's output does
not activate and the control unit gives an input phase fault.
11.10.2 Option board settings
The NXP control has fixed option boards A1A2BHB100. The option boards have jumpers which you
may need to set according to the external wiring and connections. See the VACON

NX I/O Board
User manual for settings. Required board settings for default wiring diagram and components are
given 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 use
Slot B, OPT-A2:
• No settings
Slot 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: Floating
Slot E: Reserved for optional board such as fieldbus
1. "U" Green LED: Supply voltage
• LED ON: Supply voltage present
2. "MIN" Red LED: Lower threshold value (under voltage)
• LED flashes: Set threshold value exceeded, set delay
time is running
• LED ON: Set threshold value exceeded, delay time
has elapsed
3. "SEQ" Red LED: Phase failure/phase sequence
• LED flashing: phase has failed, set delay time is
running
• LED on: phase has failed, delay time has elapsed
4. "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: 0.1s
6. "MIN" potentiometer: Lower threshold value
• 400-500Vac: ≥360Vac
• 500-690Vac: ≥450Vac
