Circ A - High Con-
densing tempera-
ture out of map
compressor
The alarm will trip if discharge pres-
sure (DP_A) > 304.2 psi (2097 kPa). If
discharge pressure exceeds compres-
sor envelope for more than 60 sec-
onds, trip alarm. If SCT > 161°F
(71.7°C), trip alarm.
Circuit A will be shut
down immediately.
Manual
If this condition is encountered, check the fol-
lowing items for faults:
•
noncondensables in the refrigerant circuit
•
condenser air recirculation
•
proper refrigerant charge (undercharged)
•
EXV operation
•
operation beyond the limits of the machine
•
condenser coils for debris or restriction
•
condenser fans and motors for proper ro-
tation and operation
•
the discharge service valves to be sure
that they are open
•
check the discharge pressure transducer
for accuracy
•
confirm unit configuration

Circ B - High Con-
densing tempera-
ture out of map
compressor
The alarm will trip if discharge pres-
sure (DP_B) > 304.2 psi (2097 kPa). If
discharge pressure exceeds compres-
sor envelope for more than 60 sec-
onds, trip alarm. If SCT > 161°F
(71.7°C), trip alarm.
Circuit B will be shut
down immediately.

down.
Manual
10075
Circuit A Low Oil
Level
When the compressor is running or
off. The alarm will trip if the compres-
sor is running and the oil level switch
is opened for more than 10 seconds
NOTE:
When the units starts the oil level
switch is verified after 2 minutes.
Circuit A will be shut
down.
Automatic, first or second
occurrence in 24 hours OR
Manual, if the alarm has
occurred more than 3 times
in the previous 24 hours
If this condition is encountered, check the fol-
lowing items for faults:
•
oil level in the oil separator
•
oil level switch wiring to the SIOB
•
board for a faulty channel
•
faulty oil level switch
•
oil solenoid valve stuck open
10076
Circuit B Low Oil
Level
Circuit B will be shut
down.
10078
Circuit A High Dis-
charge Gas Tem-
perature
Tested when compressor is running:
The alarm will trip if the discharge gas
temperature is higher than 210°F
(98.89°C) for more than 90s OR
higher than 215°F (101.6°C) for any
period of time
Circuit A will be shut
down
Manual
If this condition is encountered, check the fol-
lowing items for faults:
•
noncondensables in the refrigerant circuit
•
condenser air recirculation
•
proper refrigerant charge (undercharged)
•
EXV operation
•
operation beyond the limits of the machine
•
condenser coils for debris or restriction
•
condenser fans and motors for proper ro-
tation and operation
•
the discharge service valves to be sure
that they are open
•
check the discharge pressure transducer
for accuracy
•
confirm unit configuration
10079
Circuit B High Dis-
charge Gas Tem-
perature
Circuit B will be shut
down
Manual
10081
Circuit A Suction
Valve closed
Tested when compressor is running.
The alarm will trip if economizer pres-
sure < suction pressure -14 psi (96.52
kPa) during startup
Circuit A will be shut
down
Manual
If this condition is encountered, check the fol-
lowing items for faults:
•
confirm suction service valve is fully open
(if equipped)
