a
Use wide straps or brackets to provide minimum length, maximum surface area ground conductors. If a leadwire must be
used, use 14 AWG copper wire. Make sure that all mechanically tightened joints along the ground path are free of non-
conductive coatings and protected against corrosion on mating surfaces.
b
Follow local and NEC 1 codes.
c
Implies no limitations beyond voltage (current times resistance) drop considerations versus wire size constraints.
d
Requires ground shield at controller end. See Fig. 2, 4.
e
Ground shield to digital ground terminal C at controller end and and PC or laptop end.

Control has failed, or has no power.
Control cannot run or communicate until a critical fault has been corrected. This state
occurs at each power up or reset. Control is in the Initiate State or Alarm Initiate State or
Alarm Hold State.
Check that only one fuel has been selected, or that HF and LF are not active at the same
time. If HF and LF are active at the same time, the red LED will also be on.
Control is in Postpurge or Standby State.
Control is in a low voltage condition.
Control is in the non-configured state.
Control is in the commissioning state.
Control is in the Run State.
Control is in manual mode.
