56 Stage's On Delay (Since Previous Stage Turned On) in Seconds (All values times 10)
57 Modbus Address (Range 1 - 247)
58 Number of Fixed Stages That Are On (Range 0 - 12)
59 0-5 VDC Input #1 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
60 0-5 VDC Input #2 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
61
0-5 VDC Input #3 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
62 0-5 VDC Input #4 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
63 0-5 VDC Input #5 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
64 0-5 VDC Input #6 Value (Temperature [°F], Pressure [PSI] or Volts [DC] (All values times 10)
65 To use secondary set points, 2ND terminal is grounded. (0 = not used, 1 = selected)
66
0-10 VDC Input Value are times 10, and rounded to nearest 0.1 VDC.
67 PWM Output Signal Value is in percent (Range 0% to 100%)
68 Relay sequencing mode (0 = FILO, 1 = FIFO, 2 = Binary Encode)
69 Pressure transducer scale (0 is temp sensor, 1 is 100 PSI, 2 is 200 PSI up to 10 is 1000 PSI.)
Modbus baud rate code (0 = 1200; 1 = 2400; 2 = 4800; 3 = 9600; 4 = 19,200; 5 = 38,400;
70
6 = 57,600 and 7 = 115,200)
71 Modbus parity code (38 is even, 54 is odd and 14 is no parity with 2 stop bits)
72 If true (non-zero), reset sequencer to factory settings.
73 High speed output (Range 0 to 100) PWM duty cycle or 0-10 VDC (100 is 10.0 VDC)
74 Low speed output (Range 0 to 100). A low speed output greater than high speed output
means as the voltage goes up, the speed goes down. (See 10 - 0 VDC Output section, page 9)
75 Output for motor off (Range 0 to 100). Example: 5 means PWM is 5% and VDC = 0.5
