Signal Patterns - Weinmann OXYMAT 3 Servicing And Repair Instructions

6.1.2 Signal patterns

The alarm signal patterns are in accordance with EN 475 (see Table of Signal Patterns). To make it possible
to distinguish the alarm sources, this standard assigns specific signal patterns to individual error situations
(see Table of Error Situations).
Since it is possible that two or more errors may occur at the same time, the alarms are weighted by the
software and the appropriate alarm pattern is output. For example: if under-pressure and overheating occur
simultaneously, the alarm pattern for overheating is output (see Table of Alarm Situations).
