  • Summary of Contents for Carrier AQUASNAP 30RA010-055 Page 1: Features/Benefits Costs less right from the start Only Carrier’s AquaSnap chillers fea- ture a compact, all-in-one package de- sign that.
  • 15 diagnostic functions. Carrier 30 Series chillers’ ComfortLink controls provide features such as chilled water temperature reset, demand limiting, compressor wear minimization and protection, temperature and pressure displays and diagnostic functions. These controls result in higher chiller reliability, simplified training and more.
  • Carrier’s exclusive remote, hand-held diagnostic unit — the Navigator™ module — provides expanded informa-tion on virtually every aspect of the AquaSnap chiller’s operation, helping technicians to quickly diagnose prob-lems and even prevent them from occurring. The Navigator provides con-venience and powerful information in.

Carrier 30RA-200-0576 PEE Air Cooled Water Chiller The AquaSnap 30RAP chiller is an effective all-in-one package that is easy to install and own. The chiller operates quietly and efficiently under all operating conditions.

Carrier chiller alarmcodes

  • 30GX and 30HXC series
  • PRO-DIALOG Control
  • Screw-Compressor Air- and
  • Water-Cooled Liquid Chillers
  • 50 Hz

The PRO-DIALOG Plus control system has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. The test function makes it possible to run a quick test of all devices on the unit. If an operating fault is detected, an alarm is activated and an alarm code is stored in the Alarm menu.

Resetting alarms

When the cause of the alarm has been corrected the alarm can be reset, depending on the type, either automatically on return to normal, or manually when action has been taken on the unit. Alarms can be reset even if the unit is running. This means that an alarm can be reset without stopping the machine. In the event of a power supply interrupt, the unit restarts automatically without the need for an external com- mand. However, any faults active when the supply is inter- rupted are saved and may in certain cases prevent a circuit or a unit from restarting. A manual reset must be run from the main interface using the following procedure:
