Corrective Actions
1. Enable Emergency Bypass Mode: This is a temporary solution that will only allow the system to function for 24 hours. a. In the event of an alarm caused by a failure of the display module, the unit will go into shutdown. In order to temporarily bypass this shutdown state, Emergency Bypass mode can be activated, refer to Section 1.21. b. Once Emergency Bypass mode has been activated, the unit will operate normally for 24 hours, a countdown timer will be shown on the display. This 24 hour window of operation will keep the load safe, and provide enough time to contact the nearest Carrier Transicold Service Center for repair of the unit. 2. Remove and replace the Display Module, refer to Section 1.9.18
