Run Cmd Source
Displays the source for the Run command as XY-nn.
X: Indicates which Run source is used:
0 = OFF
1 = AUTO
2 = HAND
Y: Input power supply data
0 = HOA keypad
1 = External terminals
3 = Serial communications (APOGEE FLN, BACnet,
MEMOBUS/Modbus, or Metasys N2)
4 = Communication option card
nn: Run command limit status data
00: No limit status.
01: Run command was left on when stopped in the PRG mode
02: Run command was left on when switching from LOCAL to
REMOTE operation
03: Waiting for soft charge bypass contactor after power up (Uv
or Uv1 flashes after 10 s)
04: Waiting for “Run command prohibited” time period to end
05: Fast Stop (digital input, HOA keypad)
06: b1-17 (Run command given at power-up)
07: During baseblock while coast to stop with timer
08: Frequency reference is below minimal reference during
baseblock
