Alarms
MIN SAFETY SUC SH
Minimum Safety Sucon Superheat. Provides a warning
that sucon line is low SH before triggering a crical low
SH alarm.
0.0°F to 50.0°F (0.0°C to 27.8°C) 0.0°F
MIN SUCTION SH
Minimum Sucon Superheat. The lowest acceptable
superheat for the sucon line. Turns system o when
exceeded longer than Min/Max SH Del.
5.0°F to 50.0° F (2.8°C to 27.8°C) 15.0°F
MAX SAFETY SUC TMP
Max Safety Sucon Temp. Provides a warning that suc-
on line temp is high.
5.0°F to 90.0°F (-15.0°C to 32.2°C) 90.0°F
MAX SUCTION SH
Max Sucon Superheat. Provides a warning that sucon
SH is high when exceeded longer than Min/Max SH Del.
25.0°F to 200.0°F (13.9°C to 111.1°C) 50.0°F
MAX SAFETY PRESSURE
Max Safety Discharge Pressure. Discharge pressure above
this value triggers High Safety Discharge Pressure alarm.
Group will stop loading stages, and begin to unload.
0.0 psig to 500.0 psig 400.0 psig

Min/Max Superheat Alarm Delay. Amount of me before
a Min Sucon SH or Max Sucon SH alarm is triggered
aer exceeding the threshold.
0 to 254 minutes
*Type 255 or ‘dis‘ and save to disable. Disabled
MAX DISCH TEMP
Maximum Discharge Temp. Triggers alarm and turns
system o when discharge temp exceeds this value longer
than Max Dis Tmp Del.
25.0°F to 300.0°F (-3.9°C to 148.9°C) 268.0°F
MAX DIS TMP DEL
Max Discharge Temp Delay. The amount of me before
an alarm is iniated when Max Disch Temp is exceeded.
0 to 254 minutes
*Type 255 or ‘dis‘ and save to disable. Disabled
MAX DISCH PRES
Maximum Discharge Pressure. Triggers alarm and turns
system o when discharge pressure exceeds this value
longer than Max Dis Pres Del.
100.0 to 500.0 psig 450.0 psig
MAX DIS PRS DEL
Max Discharge Pressure Delay. The amount of me
before an alarm is iniated when Max Disch Pres is
exceeded.
0 to 254 minutes
*Type 255 or ‘dis‘ and save to disable. Disabled
