*The TG230/TT300 compressor allows for adjustment of this setting.
Compressors which are placed in Air-Cooled applications can have this value increased up to 4.8.
NOTE
Pressure ratio must be calculated using absolute pressures. Refer to the
OEM Programming Guide
to identify the specific register
associated with the Pressure Ratio Alarm Limit.
Beyond these control limits, the Maximum Design High-Side Pressure for the compressor is
shown in Table 5-4.

NOTE
While the values here are represented in Gauge Pressure, the values in the registers will be defined in Absolute Pressure. Refer
to the
OEM Programming Guide
to identify the specific registers associated with the Discharge Pressure Alarm and Discharge
Pressure Trip Limits.
The compressor will also adjust its operation if the pressure ratio exceeds the alarm limit.
The Pressure Ratio alarm limit is defined in Table 5-3.
5.3 Maximum Discharge
Temperature
The maximum temperature that the compressor can operate is regulated directly by the Trip
Limit.
The Maximum Discharge Temperature Limits are defined in Table 5-2.
