Section 7 • Alarms and Trips

Overview

The Alarms and Trips screen allows the operator to view and adjust settings for compressor safety and alarm set- tings, see Figure 7-1. Alarms and Trips Screen. Vission 20/20 uses Alarms as a way to notify the operator of running parameters that if left unchecked could result in the compressor shutting down due to a trip. Trips are the conditions that exceed the safety limits of the com- pressor or refrigeration system and stops the compres- sor. Trips are always displayed as a red banner and alarms are yellow banners on the top and bottoms status bars. Alarms and trip conditions are also logged to provide an operational history for the operator. Both alarms and trips will be logged in the event list accessible from the menu screen. Trips also trigger the input/output screen to take a snapshot of all input and output values as freeze screen. The freeze screens are available as left side tabs in the input/output screens and are very useful as a troubleshooting tool for the operator.

Alarms and Trips Setpoints

Low Suction Pressure (Alarm & Trip):

•This is the low suction pressure safety. This safety is active in both temperature and pressure control modes. An alarm or trip will be activated if the suc- tion pressure falls below the setpoint values.

High Discharge Pressure (Alarm & Trip):

•This is the high discharge pressure safety. The alarm or trip will be activated if the discharge pressure rises above the setpoint value.

High Process Temperature (Alarm only)

•This alarm is active when the process temperature is at or above the setpoint value. There is no trip setpoint.

Low Process Temperature (Alarm & Trip):

•This is the low control temperature safety. This safety is active when process temperature control has been
