Further parameterization options: 

1. “Button lock”  

Advancing the display using the LCD buttons can be blocked or enabled by telegram. 
When locked, operating the LCD buttons has not effect. 

2.  “Service loop lock”   

Calling the service loops (LOOP 1...LOOP x) can be blocked or enabled by telegram. If 
the service loop is locked, operating LCD button 1 has no effect. 

3.  “Display lock” (also known as start-up lock or NEOVAC lock)

 

 

The unit display can be locked or enabled completely by telegram. If the display is 
locked, the figure “8” and all decimal points blink.   
Note: In this state, it is no longer possible to see whether the calibration seal is set! 

 

 

Display locked (blinking) 

4.  “Power saving mode”  

Power saving mode can be locked or enabled 

(default)

 by telegram. 

 

If power saving mode is enabled – and the calibration seal is set – switchover to 

power 

saving mode

 is performed after 15 minutes if no button is pressed (and no data traffic 

takes place).    
If power saving mode is locked, the LCD display is permanently active. 

The locking functions 1 to 4 above can be combined.
