status: Read register 404100 to see
the status of the pump. See Appendix A, Table
6, for a description of each bit.
• Example 1: Register 404100, bit 1, reads 1 if
the pump is currently moving.
• Example 2: Register 404100, bit 2 reads 1 if
the pump has an active alarm.

deviations: Read register
404112 to 404115. Each bit in these registers
corresponds to an alarm or deviation. See
Appendix A, Table 5. I
• Example 1: Pressure falls below the minimum
setting entered on Setup Screen 2. It will show
on bit 4 of register 404113 if minimum pressure
is set to Alarm, and on bit 5 of register 404113
if minimum pressure is set to Deviation.
• Example 2: The system is set up for a
pressure transducer on Setup Screen 8, but no
transducer is detected. It will show on bit 1 of
register 404114.

Read registers 404101 to 404105. Note that
pressure is available only if a pressure transducer
is connected to the display. Register 404104
shows the pressure on transducer 1. Register
404105 shows the pressure on transducer 2. See
Appendix A, Table 7 for units for these registers.
• Example 1: If register 404101 reads 75, the
pump speed is 7.5 cycles/minute.
• Example 2: If register 404103 reads 67, the
pump is operating at 67 percent pressure.
