70304G WITH mA-OUTPUT 

The controller 

70304G

 is also available with a mA-output. This output is also configurable. The output 

signal and the temperature range are adjustable. 

 

 

17.1  ADJUSTING SIGNAL TYPE AND TEMPERATURE RANGE 

To adjust the signal type and temperature range:  

 

PGM-key, 

USEr

 up to 

Conf

, PGM-key, 

 up to 

OutP

, PGM-key, 

 up to 

OutA

, PGM-key, 

Out6

PGM-key, 

Fnct

 

SiGn

, PGM-key, 

SiGn

 blinking, with 

 or 

 choose signal type:  

0 = 0-10V 

1 = 2-10V 

2 = 0-20mA 

3 = 4-20mA (factory setting) 

 

Takeover of the adjusted value takes place after 2sec. 

 

 up to 

0Pnt

 (zero point of the temperature range): PGM-key, 

0Pnt

 blinking, with 

 or 

 adjust zero 

point (0,0 = factory setting). 

 

 up to 

End

 (end point of the temperature range): PGM-key, End blinking, with 

 or 

 adjust end 

point (200,0 = factory setting).

DECOMMISSIONING 

 

 NOTE!

 

 

The place of installation of the temperature controller must be protected 

from frost also in the time in which the unit is deactivated.

 

 

No particular measures are necessary for brief decommissioning of the temperature controller.
