5 General Specifications
* The TG230/TT300 compressors, the alarm and trip settings are default to lower values of operation which are
typcially deemed appropriate for Water-Cooled condiitons.
These values allow for adjustment for compressors placed in Air-Cooled applications which can have the value
increased up to 1730 kPa(g)/250 PSIG for the Alarm and 1800 kPa(g)/260 PSIG for the Trip.

Alarm Trip
The maximum pressure that the compressor can operate is regulated directly by two control
settings: (1) Alarm Limit and (2) Trip Limit. It is also controlled by a Pressure Ratio alarm limit
monitoring the ratio between the Discharge and Suction Pressures.
