IFW All Open or Short and Solid State Starter Installed.
MMR All starting a. The bearing temperature at sensor #1 exceeded 180 + or - 5F
and running (82.2 C) for 0.5 -2 seconds (Note: BT, WT, and DT may be
modes "instantaneous trip" but consistent with the analog input filtering
function.), and
b. This function is enabled at the Clear Language Display.
MMR All starting a. The bearing temperature at sensor #2 exceeded 180 + or -5 F
and running (82.2 C) for 0.5 - 2 seconds. (Note: BT, WT, and DT may be
modes "instantaneous trip" but consistent with the analog input filtering
function.), and
b. This function is enabled at the Clear Language Display.
MAR All a. The discharge temp. exceeded the trip value; 200 F + - 5 F.
The Discharge Temp Cutout is adjustable at the Clear Language
Display.
b. Time to trip from trip value exceeded shall be 0.5 to 2.0
second. (Note: BT, WT, and DT may be instantaneous trip" but
consistent with the analog input filtering function.)
c. The diag. shall reset automatically 50 F below the trippoint.
MMR Any Start The Motor winding temp. at Sensor #1 exceeded 265 F + or - 15
and Run F for 0.5 - 2 seconds. (Note: BT, WT, and DT may be
Mode "instantaneous trip" but consistent with the analog input filtering
function.)
MMR Any Start The Motor winding temp. at Sensor #2 exceeded 265 F + or - 15
