6.3. Functions of the push-buttons during measurement

 

 

The DT4220 E is a modern type of process indicator family. The old 
type (DT4220) and this new type have same functions and same 
options but the function of buttons at menu not compatible. 
The following figure shows the push buttons: 

 

 

 

 
(1) 

 Menu

 button: Entering the menu. 

When you push this button, the instrument will ask for a password 
(code) in accordance with Chapter

 7.1. Functions of the push-

buttons during

 navigation in the menu

, when the right code has 

been given, it enters into the menu. During this time the instrument 
works continually and the outputs are refreshed. If no keys are 
pressed for a period of 5 minutes, the instrument exits from menu. 
 
(2) 

 button: displaying firmware version. 

The firmware version remains on the display as long as the button is 
being pressed. 
Format: YY.M.DD: YY = year, M = month, DD = day. 
 
(3) 

 

Esc

 button: displaying the status of the limit output and clearing 

the alarm (alarm acknowledgement). 
It's functionality depends on the operating mode of displaying the 
limits. In default factory setting this function is ‘dynamic’, therefore It 
displays the limit output state as far as this button is pressed.
