* [LIMIT] is shown on the LID as temperature, pressu r e, voltage, etc., predef in ed or selected by the

operator as an override or an alert.

Table 10D — Prestart Alerts: These alerts only delay start-up. When alert is corrected, the start-up will continue. No reset is necessary.

if additional start is required.
Reassess start-up requ ire-
ments.
Prestart Alert High Motor Temper a-
ture MTRW VALUE exceeded limit
of [LIMIT]*. Check motor tem-
perature.
Check motor cooling line for
proper operation. C heck for
excessive starts within a short
time span.
Prestart Alert High Bearing Tempera-
ture MTRB VALUE exceeded lim it of
[LIMIT]*. Check thrust bearing
temperature.
Check oil heater fo r proper
operation, check for low oil
level, partially closed oil sup-
ply valves, etc. Check sensor
accuracy.
Prestart Alert High Discharge Temp CMPD VALUE exceeded limit of
[LIMIT]*. Check discharge tem-
perature.

discharge temperatu re to
cool. Check for excessive
starts.
Prestart Alert Low Refrigerant Temp ERT VALUE exceeded l imit of
[LIMIT]*. Check refrigerant tem-
perature.
