4.6 Error messages
In the LCD display errors from the evaluator and probes are displayed number-coded and in plain text
abbreviations.
If there is a DU present (optional), errors by evaluator and probes are displayed in the 7-segment
display number-coded and 2-digit.
For analysis and error correction see Chap. 10.
4.7 Overview of the system properties
- Up to 32 probes (minimum 2 probes) for quasi-continuous level measuring
- Can be used up to PS = 200bar // TS = 367°C
- Double power supply for high availability (redundancy) with display of failure of one power supply
- Self-monitoring electronics for high system safety during monitoring functions
- wire breakage monitoring
- Adjustable switching delay on all outputs for avoiding false signals
- 1 alarm output (SPDT) for the reaction in case of low water and/or overfilling
- 1 error output (SPDT) for the display of (electronic) system errors
- 7 user specific and programmable outputs (SPDT) enable:
* individual switch points e.g. horn when exceeding or falling below a fill level
* double switch points e.g. for a pump control
In the case of identical programming of two outputs a “DPDT output” is possible.
- 1 4mA .. 20mA output for loads up to 500Ω, not galv. isolated
- Remote indicator (DU, optional) with 4mA .. 20mA output for loads up to 500Ω, not galv. isolated,
as many as desired
