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 Manual to identify the specific registers associated with the Discharge Pressure Alarm and Discharge Pressure Fault 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 Maximum Pressure Ratio Limits.

*The TGS230/TTS300 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 Manual 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
Maximum Allowable Pressure [PS].
